《仙佛合宗語錄》Vol. 1

This dialogue records a conversation between Prince Zhu Taihe of the Ming Dynasty (Daoist name Taihe, style name Yunshui) and Master Wu Chongxu regarding doubts about cultivating the "true medicine" (referring to the essential substances needed for Neidan/internal alchemy practice). Zhu Taihe mentioned that while he had heard of the term "true medicinal substance," he didn't know how to discern which elements within oneself constituted genuine cultivation materials.

Master Wu Chongxu replied that the true medicinal substance was none other than "true Jing (essence)." He explained: Only the Jing that can be used for spiritual cultivation deserves to be called "true Jing"—what cannot be used doesn't qualify. The turbid reproductive essence produced through sexual intercourse belongs to postnatal acquired energy and cannot be considered true Jing, because this essence has already solidified into coarse material form. It cannot revert to the formless, immaterial primordial Qi (innate energy), let alone transform further into primordial Shen (higher consciousness energy). Quoting the Zhuangzi and the teachings of Master Chen and Ge Hong (Baopuzi), he pointed out that clinging to sexual cultivation techniques while neglecting the Golden Elixir practice was utterly foolish.

True Jing refers to the primordial essence innate to one's being—the original Qi that existed even before the formation of heaven and earth. This primordial energy is called Yuan Qi when in stillness and Yuan Jing when in motion, yet they are fundamentally the same. This constitutes the very foundation for attaining immortality through cultivation, the authentic and usable "true Jing."

Wu Chongxu concluded by observing that while many in the world speak of "true Jing," they invariably mistake the postnatal reproductive essence acquired through intercourse for the real substance. Having never received authentic transmission from true immortals, such people fundamentally cannot know what true Jing actually is—they merely appropriate the terminology to deceive others.

This scripture discusses the essential principles of cultivating Jing (essence) and Qi (vital energy) in Daoist practice. It points out that those entangled in worldly desires are not genuine practitioners who devote themselves to the Dao, and even when hearing profound truths of the Great Way, they fail to comprehend them. Some mistakenly identify the physical semen produced through sexual intercourse as the "true essence" required for cultivation.

Master Chongxuzi, responding to Gu Yutao's inquiry in the Hermitage of Daoist Seclusion, explains: The cycle of movement and stillness, life and death in the human body follows inevitable natural laws. Yet without authentic transmission, even when the opportunity arises to encounter the manifestation of primordial Qi (Yuanqi, the original formless energy of life), one will miss it due to inability to distinguish truth from falsehood. The key lies in understanding the "reason why" (fundamental principle) — since humans developed sexual desire and intercourse, their primordial Qi has gradually dissipated. Only by replenishing it with formless energy of the same category can longevity be achieved. The tangible sexual essence (acquired semen) belongs to a lower level and cannot replenish the higher-level primordial Qi.

The text emphasizes that gathering and supplementing primordial Qi requires seizing the correct timing. Without comprehending this principle, even attempts to replenish essence and energy will never achieve true abundance, making immortal attainment impossible. Those who genuinely understand this principle can cultivate their primordial Qi to fullness and perfection, subsequently attaining embryonic respiration, deep meditation, and spirit liberation. When ancient sages spoke of "within the vast darkness there exists essence," they precisely referred to this primordial true essence. Only by mastering this fundamental principle can one attain the Dao and achieve immortality. Superficial worldly people who only understand crude platitudes can never fathom these profound mysteries.

Finally, it clarifies that the semen produced through ordinary sexual desire (intentional essence) belongs to the category of acquired reproductive essence, completely distinct from the primordial true essence required for cultivation.

This dialogue explores how "having thoughts" and "thoughtlessness" affect spiritual cultivation. When lustful or distracting thoughts arise, the generated essence becomes post-heavenly "degenerate essence" – a depleted form of vital energy that cannot support longevity. Buddhist scriptures similarly warn that seeking enlightenment while clinging to lustful attachments only perpetuates samsaric rebirth. Authentic practice must first silence these delusional thoughts.

The state of "thoughtlessness" refers to the emergence of primordial essence (Jing), the most fundamental vital energy, during profound stillness. Ordinary people may occasionally enter this state but often miss the opportunity due to lacking proper cultivation methods. Some recognize primordial essence exists yet fail to grasp the precise timing for its application, thus squandering precious moments of potential transformation.

The text identifies two common failures in practice: First, mistaking degenerate essence produced by lust for true essence inevitably leads to failure. Second, even those who recognize true essence often lack the discernment to identify its subtle manifestations and proper utilization methods. These shortcomings typically stem from learning only mundane, worldly techniques.

The methods transmitted by such worldly practitioners are either licentious arts or hypocritical theories advocating purity while remaining impure in body and mind. Some feign purity to avoid ridicule, but these are ultimately deceptions for fame and material gain. Seekers who naively embrace such methods in hopes of immortality labor in vain. True cultivation requires understanding the profound principles behind genuine essence's emergence and mastering the exact timing and methods for its refinement.

This scripture primarily discusses the essential points of Neidan (internal alchemy) practice, pointing out that although many cultivate purity on the surface, their inability to grasp the true timing and methods ultimately prevents them from attaining immortality.

The text first observes that some practitioners, though sincerely devoted to the path of purity, never encounter authentic Daoist transmission. Lacking knowledge of the "true moment when the medicinal substance arises" (the critical juncture when Jing and Qi naturally manifest within the body) and the "true timing for gathering the medicine" (the precise moment to collect vital essences), they ultimately fail to refine the Golden Elixir. Such practitioners remain ordinary mortals bound to the cycles of birth, aging, sickness, and death.

It further explains that the "medicine" (referring to the body's primordial Qi) fails to manifest authentically because practitioners miss the crucial gathering moment, leaving their untapped primordial Qi incomplete. Without completing this foundational energy, the Golden Elixir cannot be formed. Such cultivation remains mere mortal striving rather than genuine immortal practice.

The scripture emphasizes that during the thoughtless state of empty stillness, when tranquility reaches its peak, the sudden emergence of a thread of vital energy constitutes the authentic primordial Jing. Though inherently present in all humans, this essence remains ineffective without the guidance of "primordial spirit awareness" (the innate consciousness) to activate and direct it.

Finally, citing the Jade Purity Supreme Mystery Virtue Scripture and Tianlaizi's White Tiger Songs, the text warns that improper cultivation leads to losing the fundamental method—like the moon lacking the Qi of heavenly metal, or metal without water's generative power. Even with authentic "true lead" (primordial essence), efforts prove futile. The celestial secrets are transmitted only to those of virtue, for ordinary mortals remain too distant from the Dao of Heaven.

This scripture reveals the core principles of attaining immortality through cultivation. The essential point lies in practitioners cultivating virtue (De) that aligns with the Heavenly Dao (Xiude Hetian), for only then can they receive genuine transmission of the immortal path. The primordial spirit (Yuanshen, one's innate spiritual nature) can discern the emergence of "medicinal substances" (the vital essence and energy required for cultivation) within the body. By mastering these opportune moments for cultivation practices, one may achieve longevity beyond death, enter and exit deep meditative states (Samadhi), and attain boundless spiritual powers.

The Lingbao Duren Jing (Scripture of Salvation) mentions that the cultivation method of harmonizing water and fire (referring to the practice of balancing Yin-Yang) is only transmitted to those with sagely virtue. Celestial immortals achieve the Dao through such secret methods, though ordinary people find them difficult to comprehend. If one cultivates virtue in accordance with the Heavenly Dao, they may become a "celestial human" (an enlightened being); otherwise, they remain forever an ordinary mortal.

Those who wish to learn the Dao and pursue immortality must first diligently cultivate virtue aligned with Heaven's principles. When superior immortals transmit Daoist methods, they require practitioners to make solemn vows (strict oaths), repent past transgressions, and abstain from future wrongdoing, lax cultivation, or indiscriminate transmission to the unvirtuous. Particularly regarding the critical secret of timing the emergence of "medicinal substances," the Duren Jing states this is the most guarded celestial mystery.

Receiving this true transmission enables one to achieve celestial immortality, attaining a state equal to Buddhahood. When primordial essence (Yuanjing) transforms into Qi (a higher-level energy), one accomplishes the spiritual power of ending all defilements, with the yang spirit (cultivated spiritual body) transcending the cycle of rebirth. Without this authentic transmission, all discussions of Zen or Dao remain empty theorizing.

The scripture concludes by stating that only through this clear revelation can practitioners understand the true nature of the primordial essence (Zhenjing) employed in the immortal path.

The true elixirs of cultivation (referring to Jing, Qi, and Shen in Neidan practice) alone can lead to the attainment of the "leak-free transcendence" (freedom from afflictions) and the emergence of the "yang spirit" (the primordial spirit leaving the body). Only then does one realize how utterly different this is from all worldly methods learned before. What worldly methods discuss is merely the turbid postnatal Jing and Qi.

If one's cultivation aligns with the Dao from the very beginning—as the ancients said, "If the start doesn't meet the true master, in the end it becomes mere antique junk"—then with authentic transmission, the practice will remain in harmony with the Dao throughout, from initial cultivation to final realization. This is the meaning behind the ancient saying: "The ninefold refinement process is ultimately the same."

With each step of understanding comes corresponding practice; with each step of practice comes deeper realization; with each step of realization comes tangible attainment. Thus one experiences the unspoken secrets, the efficacy of realization, and the swiftness of attaining the Dao. Once one comprehends the emergence of the true medicine (primordial Qi) and the timing for gathering it—when the timing is correct, the medicine is genuine, the Jing and Qi are authentic—then the work of gathering the medicine can begin.

When the gathering practice becomes proficient, causing Jing and Qi to follow the primordial Shen and condense into the Qi cavity (lower Dantian), and through celestial circulation they are refined through steaming and tempering, then over time the work of refining Jing reaches completion. This transforms Qi into abundant potency, yielding the "great medicine" (Golden Elixir), achieving leak-free transcendence and attaining the preliminary fruit of immortality. Only then does one understand the profound mysteries the celestial immortals rarely transmit, and how remarkably efficacious the fruit of longevity truly is.

In summary: the hundred-day foundation establishes longevity; the ten-month "gestation" (internal elixir formation) leads to samadhi and spirit emergence; after the yang spirit is perfected, spiritual powers become limitless. As the ancients said, "Attainment requires only a year or two"—unlike those heterodox paths that spend years on misguided sexual practices, only to face regret at deathbed in sickness and suffering. This is not a realm worldly people can comprehend or realize. How lamentable that people are deceived by false teachers!

Seeking the immortal path without accumulating immortal virtue (De), while remaining ignorant of where the true principles of immortality lie—how can such people ever understand or realize it? Worse still, when false teachers twist the orthodox teachings from immortal scriptures to justify their heresies, generation after generation falls prey to deception without suspicion, with none able to reform. Alas, the victims lose both the immortal path and their inherent worldly life.

Someone asked: The ancients spoke of distinguishing clear and turbid water sources—how does one differentiate? The answer: Water symbolizes true Jing; clarity refers to primordial Qi, while turbidity belongs to postnatal Jing and Qi. The "source" denotes the origin from which Jing and Qi arise—this is what the immortal sages...

Daoist scriptures clearly state that the teachings left by immortals and sages exist to enlighten those with destined affinity—only genuine practitioners can comprehend their true meaning. Yet worldly people often misinterpret the words of sages, misleading later students. These individuals, still unenlightened themselves, rely on mundane understanding or even bypass proper doctrinal texts, drawing instead from erroneous commentaries by misguided thinkers while imagining themselves awakened. This transmission of confusion has caused immeasurable harm throughout history.

Regarding the crucial cultivation concept of "primordial essence" (original life energy), it cannot be simplistically categorized as "having form or formless." True primordial essence is formless Yuanqi (primordial Qi) that transcends physical judgment. What appears with visible form is actually the turbid essence of the acquired world. This post-heaven essence, governed by ordinary consciousness, dissipates even before manifesting physically, making return to the origin impossible. If essence doesn't combine with lustful thoughts, it won't condense into turbid form; once form appears, it signifies the true Qi has been exhausted through indulgence—a heretical view completely alien to orthodox Daoist practice. Such theories plant seeds of spiritual ruin, echoing the ancient warning: "When Qi exhausts, death follows."

Authentic Daoist cultivation involves apprehending the primordial essence (life's foundational source). When stillness reaches its peak, this essence spontaneously stirs—a moment of abundant Qi movement and pure origin, constituting the true "medicine" (alchemical ingredient). This natural activation follows cosmic rhythms, distinct from artificial agitation through deluded thoughts. As Yuanshi Tianzun (Celestial Worthy of Primordial Beginning) reveals in the Liberation of Body Scripture: "How can one attain Dao without understanding the true mechanism of movement/stillness or comprehending the wondrous principle of eternal truth?"

When primordial spirit (original awareness) awakens, it naturally unites with primordial essence—this is called "awakened joining awakened." Here, practitioners follow spontaneous gathering and refinement processes, free from worldly distractions. Each moment of proper practice cultivates another moment's "yellow sprout" (elixir seedling), making the Golden Elixir attainable and immortality possible. These discernments about pure versus turbid energy sources share fundamental principles with the previous chapter's dialogue, though presented from different perspectives for complementary elaboration.

Daoist cultivation emphasizes the harmonious interaction of Original Jing (primordial life essence), Original Qi (primordial vital energy), and Original Shen (primordial consciousness). When practitioners reach a certain level of attainment, their Original Shen can naturally perceive the optimal moments for cultivation, achieving a union as inseparable as husband and wife. The Perfected Xu Xun (Xu Jingyang) taught that internal Qi circulation must synchronize with breathing patterns, while Yu Yan (Yu Yuwu) revealed that the profound mechanism of cultivation lies in entering deep meditative stillness.

During the winter solstice practice, one should first seal the lips in silence ("closing the openings"), calm the mind in stillness, allowing the Gold (Original Shen) and Mercury (Original Jing) to merge within the Dantian (furnace), like the sun and moon conjoining. Only through such concentrated unification of spirit and energy can the Golden Elixir (Neidan) be formed. Restless thoughts and dissipated Qi will instead cause self-harm.

The term "cultivation effort" here refers to the work of gathering medicinal essences (collecting Jing-Qi), harmonizing Yin-Yang, and refining the internal elixir; "a moment" signifies the microcosmic orbit circulation; while "Yellow Sprout" denotes the genuine Qi formed through internal refinement of Shen and Qi. When Lü Dongbin (Immortal of Pure Yang) asked Zhongli Quan (Perfected Zhongli) about the nature of Yellow Sprout, he received the answer: the union of True Dragon (Yang Qi within the Li Palace's true water) and True Tiger (Yin Qi within the Kan Palace's hidden fire).

The Golden Elixir (Jindan) is the numinous energy formed when Original Shen refines Original Jing, also called Yellow Sprout or Great Medicine. Ingesting this elixir assists in forming the spiritual embryo (internal elixir) and nourishing the spirit, ultimately leading to immortal attainment. The completion of the Golden Elixir represents fulfillment of life cultivation (ming gong), while mental serenity signifies completion of nature cultivation (xing gong) - hence the saying that perfected elixir brings immortality within reach.

When the mind becomes entangled in worldly distractions, the generated Jing-Qi belongs to the realm of post-heaven conceptual thinking. This turbid vital essence cannot be used for cultivation because it lacks genuine Qi and cannot produce Yellow Sprout, ultimately failing to escape the cycle of life and death.

Though many pay lip service to Daoist practice, most remain mired in mundane emotions and desires. The arousal of passions produces post-heaven essence - not born from meditative stillness but accidentally triggered by external stimuli. This turbid energy source proves useless for internal cultivation. Thus Guang Chengzi warned against dissipating vital essence, and Perfected Chen Tuan declared that insufficient essence prevents elixir formation. These failures stem from unresolved worldly attachments and unextinguished lust, keeping practitioners trapped in the lowest realms of the desire world.

This scripture primarily discusses the importance of maintaining mental purity during spiritual cultivation. Though practitioners may appear to live ordinary lives externally, if their inner selves are tainted by desires, even surface-level practice will fail to attain the Dao (the Way).

The text explains that the human primordial spirit (Shen, or innate consciousness) is originally pure but easily polluted by mundane thoughts. Just as turbid water cannot yield purity, a mind disturbed by desires renders cultivation futile. Multiple Daoist masters emphasize this point: Lady Wei warned that practicing with lustful intentions invites divine punishment; Bai Yuchan observed that transcending worldly desires is the greatest challenge; Master Wang Yuyang cautioned that following desires inevitably leads to failure.

The crux of cultivation lies in understanding the true meaning of the character "source" (源)—just as a water source symbolizes the mind's origin. Pure thoughts make practice effective, while turbid thoughts render it fruitless. During meditation, the spirit (Shen) and vital energy (Qi) must remain synchronized: stillness in stillness, movement in movement. True practitioners achieve unity in motion and stillness, undisturbed by external influences.

When the mind chases delusions outward, it dissipates vital essence (Jing) and energy (Qi). Conversely, maintaining inner purity enables union with the Dao. Guang Chengzi taught that stillness must reside in spiritual intent, while movement arises from spiritual mechanism. Yu Yu further noted that Golden Elixir (Jindan) cultivation depends on harmonizing spirit and energy. These teachings all emphasize the fundamental principle: cultivation requires preserving mental purity, free from desire's interference.

The essence of cultivation lies in returning the mind to its original purity. Just as alchemical refinement requires precise control of furnace fire, a practitioner achieves the state of serene unity through returning to the fundamental source in a single thought—this is the foundational principle of the immortal path (Xiandao). Failure in this leads to the entanglement of the six senses (liugen) with external phenomena (liuchen), resulting in turbid unity and inability to return to one's true nature.

Yuanshi Tianzun (Celestial Worthy of Primordial Beginning) states in the Scripture of Attaining the Dao and Realizing the Body: "When thoughts are tranquil, the Shen (spirit) remains complete, like clear water; when thoughts are agitated, the Shen scatters, like turbid water." Chen Xubai similarly observed: "A restless mind prevents the Shen from uniting with Qi (vital energy), and bodily agitation prevents Qi from nourishing the Shen." Thus, Patriarch Qiu Chuji emphasized working at the "ground of the heart" (xindi)—the root of the mind—by completely relinquishing worldly attachments. The Śūraṅgama Sūtra likewise teaches: "When the senses no longer grasp at external dust (objective phenomena), the six roots lose their objects, enabling return to the source."

These four principles confirm the cultivation truth of unifying the dynamic and quiescent states of Shen and Qi. Here, the immortal path and Buddhism converge. The Chan (Zen) maxim "a single stirring thought is already wrong" expresses the same idea. Qiu Zu's instruction to "work at the ground of the heart" means maintaining both awareness and stillness, ultimately realizing the mind's true nature. The Chan mind is free of thoughts; Chan nature is unborn—this stands in complete opposition to worldly pursuits. Even the Dharma must be relinquished, let alone mundane affairs. Total letting-go leads to awakening one's true nature.

In the Śūraṅgama Sūtra, "dust" refers to the six external objects (form, sound, smell, taste, touch, and mental phenomena); "grasping" (yuan) means clinging; "roots" are the six sense faculties (eyes, ears, nose, tongue, body, and mind); and "pairing" (ou) denotes the interaction between roots and dust. The meaning is this: when the mind does not cling to external dust, the eye faculty no longer engages with form, the ear no longer engages with sound, and so forth. "Counterflow" (fanliu) describes water flowing upstream, akin to Dongshan Liangjie's phrase "cave waters flow backward"—precisely what Daoist immortals call returning to the True Unity's waters. When this stream of True Unity reverses, the root of birth and death is severed, revealing the pure original nature alone. With the six roots no longer grasping outward, the work at the ground of the heart is perfected.

Question: Why distinguish pure Qi (qingqi)?

Answer: Pure Qi is heaven's intrinsic quality. To achieve celestial immortality (tianxian), one must make one's Qi identical with heaven's to merge with the Dao. Thus, Lü Dongbin declared: "Only by refining the medicine of pure Yang can one ascend as celestial immortal." Master Tan Chuduan similarly wrote in Water-Cloud Anthology: "To tread the cloud-path in this life, without merging with emptiness, no immortality is attained." These all confirm that only by obtaining Qi of heavenly quality can one assuredly realize the celestial immortal fruition.

During cultivation practice, if even the slightest aspect of one's physical form fails to attain the profound mystical state, one remains bound to the heavy, turbid substance of earthly existence, only able to harmonize with the De (Virtue/Power) of the earth. Ultimately, this leads only to the attainment of terrestrial immortality (earth-bound transcendence).

The reason such practitioners are called terrestrial immortals is precisely because they cannot break free from earthly constraints. As Lü Dongbin (the Immortal of Pure Yang) stated, this level of cultivation merely allows the physical form to endure in the mundane world—though one may live for millennia, celestial ascension remains impossible. Those seeking to achieve celestial immortality must clearly recognize this distinction and continue their upward cultivation journey.

Regarding the question of "original essence" (Yuanjing): Essence (Jing) exists in two forms—the primordial essence (innate vital energy) and lustful essence (acquired essence tied to desire). Their fundamental difference lies in what governs them. Yuanjing represents the formless quintessence present when the human body reaches profound stillness—this is the original Qi (primordial life force). As Guangchengzi explained to the Yellow Emperor, the highest Dao essence is profoundly mysterious and unfathomable.

Though Yuanjing can transform into acquired physical substances, without the guidance of consciousness (Shen), it remains in its original formless state. Even if left uncollected and uncultivated for extended periods, it merely persists as scattered primordial Qi. The common misconception that semen must be promptly "harvested" or it solidifies into form is entirely erroneous—such notions stem from the baseless theories of bedroom arts. The Yuanjing discussed in Daoist immortality practice is fundamentally different.

Only when consciousness directs it toward generative functions does Yuanjing transform into acquired essence—this is not a spontaneous process. When hidden in stillness and naturally activated at the extreme point of quiescence, the resulting "essence" actually represents the physiological manifestation of heaven-earth-humanity's natural cycles. Therefore, Neidan (internal alchemy) practitioners call this stillness-born substance "essence"—though it's not ordinary semen, hence termed Yuanjing.

When Yuanjing remains undisturbed, primordial Qi (Yuanqi) remains inherently abundant. With sufficient Yuanqi, one can form the inner elixir (Neidan), circulate it through the cosmic orbits, and ultimately nurture the yang spirit (advanced spiritual form). The so-called "using essence to replenish essence" refers to how ordinary semen loss through desire depletes Yuanqi. Immortal sages teach practitioners to preserve the internally generated Yuanjing, cease its dissipation, and return it to replenish the unactivated Yuanqi—thereby restoring its fullness.

This passage primarily discusses the essential importance of replenishing Jing (essence) and Qi (vital energy), the innate life force, in the cultivation of longevity. Just as a sixteen-year-old youth possesses abundant essence and vitality, this forms the foundation for achieving immortality. Without replenishing these fundamental energies, one can never attain the Daoist path of eternal life.

Both the Jade Clarity Supreme Merit Scripture (Yuqing Shangmiao Gongde Jing) and the Great Return Heart Mirror (Dahuan Xinjian) emphasize that without proper cultivation, or if one fails to practice when Yang energy arises, true longevity cannot be attained. In internal alchemy (Neidan), one must not use "interactive essence" (the acquired essence produced by lustful desires), as this kind of essence is often generated through the eyes seeing beauty, the ears hearing seductive sounds, or the mind dwelling on impure thoughts. Such essence, stimulated by external influences, lacks purity and sufficient energy, making it unsuitable as the foundational material for alchemical refinement.

The ancient immortal Guangchengzi once warned the Yellow Emperor: "Do not disturb your essence, and you shall attain longevity." Similarly, Chen Niwan stated: "If the roots of a tree are rotten, how can its leaves remain green? If the Qi Sea (lower Dantian) churns like waves, death comes swiftly as an arrow." Once essence has been corrupted, how can it possibly return to its original, formless, innate state? Thus, the distinction between the immortal path and heretical practices lies in the absolute rejection of essence produced through lustful desires.

Master Wang Chongyang taught that to recognize the "subtle and imperceptible" (the profound state of the Dao), one must extinguish all desires and act contrary to worldly habits. Zhang Ziyang pointed out that those who rush their cultivation and use Yang energy generated by lustful thoughts to refine the elixir will only produce illusory medicine—this acquired essence dissipates quickly, not only failing to prolong life but actually shortening it.

The Commentary on the Yellow Court Scripture (Huangting Jing Zhu) warns practitioners that a single act of sexual indulgence can deplete a year’s worth of accumulated medicinal energy (essence), while two acts can erase two years’ worth—all prior cultivation efforts will be wasted. Therefore, genuine immortals are extremely cautious in this regard.

Wu Shouyang (Daoist name Chongxuzi) further elucidates the key points of cultivation in his Recorded Sayings on the Immortal-Buddha Unity:

When cultivating the Daoist path, one must maintain the concentrated accumulation of Jing (essence) and Qi (vital energy). If one indulges in sexual dissipation, the hard-earned condensed essence will be greatly depleted. While it's commonly said that such indulgence wastes medicinal potency equivalent to a year's cultivation (referring to alchemical achievements), the actual loss may be even greater. Since transforming essence into the Golden Elixir (the refined substance of Neidan practice) is inherently extremely difficult, if one is fortunate enough to achieve this alchemical refinement, even greater caution must be exercised to guard it against depletion through sensual desires.

Zhang Sanfeng (also known as Zhang Ziyang) spoke of the "Primordial Master" as referring to the fundamental source that generates pre-heaven essence. If post-heaven essence (referring to physical semen) is not dissipated, pre-heaven essence will not be lost; when post-heaven essence is abundant, the pre-heaven essence it transforms will also flourish. If physical semen is exhausted through lust, pre-heaven essence loses its foundation for transformation, leading to conditions of severed yang energy—this is the meaning behind "the Primordial having no master."

Zhang Ziyang particularly emphasized: The refinement of the Great Medicine (advanced Neidan) cannot be separated from the Three Treasures of Jing, Qi, and Shen (essence, vital energy, and spirit). However, one must understand that the true medicinal materials (cultivation ingredients) are the refined products derived from these three, not their ordinary forms used directly.

To summarize the essential method: To refine primordial essence (pre-heaven essence), one must first grasp the timing of its emergence. Only by timely intervention during its genuine moment of activation can one obtain the cultivatable primordial essence. Missing this critical moment yields only insubstantial, useless energy unsuitable for cultivation.

The text illustrates this principle poetically: Primordial essence is called "pre-heaven" because it exists in the undifferentiated chaos before heaven and earth took form, having no concrete manifestation. Just as the Taiji (cosmic origin) spontaneously stirs within supreme stillness, this initial movement of spiritual mechanism represents the opportunity for immortal cultivation. Practitioners must apply their methods during the subtle moment when essence appears between movement and stillness—if one waits until it fully manifests as post-heaven physical essence, the optimal timing is lost. This mastery of the mysterious firing process that "generates being from non-being" constitutes the core secret of immortal and Buddhist cultivation.

The key to obtaining Primordial Qi (the purest vital energy within the human body) during cultivation lies in maintaining clear awareness while entering the mysterious state of subtle perception, for only then can one truly touch the profound realm of authentic mystery.

The "subtle perception" mentioned here refers to a special state of awareness that perceives the delicate transformations of Qi movement within the body. Ordinary people often mistakenly believe awareness means perceiving external phenomena, when in truth, genuine awareness involves observing internal states—a practice only truly understood and implemented by celestial immortals (Tianxian) in their cultivation. Precisely because this method can only be transmitted by celestial immortals, worldly beings remain ignorant of it. Therefore, those seeking immortality must comprehend this internal subtle perception to truly enter the gate of cultivation.

The poem particularly emphasizes "perceiving the true mystery," reiterating that this subtle perception resembles the awareness during the initial stirring of Qi movement. This serves as crucial guidance for future practitioners—without grasping this point, so-called immortality cultivation remains mere empty talk. The poem fully reveals the esoteric mechanism of cultivation; genuine practitioners must contemplate and practice this truth, or they won't even find the gate to enter.

Regarding four specific questions about cultivation steps:

First question: "Recognizing and gathering the medicinal substance" (referring to methods for collecting and refining the nascent genuine Qi when it arises)—When the pure Yang Qi (Primordial Jing-Qi) emerges within the body, it awakens practitioners from worldly delusions. This stirring of Yang energy constitutes the "medicinal substance" (material for cultivation). Lü Dongbin's phrase "the first stirring of Yang" describes the early cultivation stage when practitioners haven't fully transcended worldly desires and sleep disturbances. At this stage, one should follow Buddhist teachings by distancing from the six sensory disturbances (sights, sounds, etc.) and maintaining wakefulness. Dreaming and wakefulness form a cyclical continuum; dreams actually signal the impending movement after extreme stillness.

Second question: "Methods of gathering"—By restraining desires and returning to one's original nature, one guides the Shen (spirit) back to the Dantian (Golden Cauldron). As Bai Yuchan taught, sitting upright in stillness serves as the method for gathering and refining.

Third question: "Applying fire to refine the elixir" (referring to circulating the celestial cycle's firing times)—Completing three hundred celestial cycles allows the genuine Qi to return to stillness through seasonal rhythms. Originally, the celestial cycle comprises 365.25 degrees; the mention of three hundred cycles here indicates pausing the fire (temporarily suspending intentional guidance) during the Mao (5-7 AM) and You (5-7 PM) periods for purification baths.

Fourth question: "Obtaining and ingesting the elixir" (referring to employing the perfected Golden Elixir)—Through stabilizing breath and harmonizing with the four seasons' rhythms, one attains tranquil stability.

This scripture primarily elucidates several key stages and considerations in Daoist Neidan (internal alchemy) practice.

Regarding the regulation of "fire times" (methods for controlling internal energy), ancient masters taught that longevity requires breath modulation. The mentioned "four seasons" refer both to critical daily periods and annual seasonal changes. As the Cantongqi (Kinship of the Three) states, one must carefully adjust practices in harmony with temporal cycles. When cultivation reaches subtle stages, maintaining meditative stillness becomes essential—this addresses how to properly apply these energetic controls during alchemical refinement.

During initial practice, when first establishing the foundation over one hundred days, only faint Yang energy manifests. After completing this foundational period, during the subsequent seven-day phase, the Golden Elixir (cultivation achievement) gathers sufficient "great Yang medicine." If this Yang energy fails to arrive, it indicates either impure "alchemical ingredients" or improper fire regulation.

Upon successful elixir formation, practitioners must guide it using the "Five Dragons" (symbolizing five cultivation energies) through the "Three Passes" (critical anatomical regions) upward to the crown before descending it for ingestion. This explains the post-refinement elixir consumption method.

After ingesting the elixir, it requires ten months of incubation in the Yellow Court (Dantian region) to gestate the Yang Spirit (refined spiritual consciousness). When matured, this spirit can transcend physical form, riding celestial cranes to roam heavenly realms freely, attaining omniscient abilities that penetrate cosmic and temporal dimensions.

The text addresses divergent views on breath regulation: some practitioners obsess over breath control, hindering progress; others completely neglect it, equally deviating from the Dao. The former fail to understand the transition from deliberate methods to Wuwei (non-action) states, while the latter miss how purposeful action emerges from non-action. Both extremes prove misguided—the former resembling Buddhism's "obstruction of phenomena," the latter akin to "indiscriminate voidness" (meaningless emptiness).

Through personal verification, the author discovered these extreme approaches not only prove ineffective but harmful, representing ordinary outsiders' partial views. The questioner ultimately inquires: what breath regulation method truly constitutes the celestial immortality path?

The matter of breath regulation (tiaoxi) cannot be fully explained in just a few simple words. For beginners, one must start with the most fundamental and elementary principles, gradually progressing to deeper understanding. Only by first grasping these basic concepts can one advance to comprehend the profound and subtle cultivation methods. All practitioners follow this same path—from shallow to deep, from coarse to refined.

Since you've already gained some insight, I can now explain in detail. Breath regulation is the foundational method for applying "fire timing" (huohou, the coordination of intention and breath) during the practice of the Lesser Celestial Circuit (xiaozhoutian, a basic Neidan technique). It encompasses key principles such as "advancing the fire" (jinhuo, guiding intention during inhalation), "retreating the talisman" (tuifu, relaxing intention during exhalation), "bathing" (muyu, the natural pause between breaths), and "nourishing warmth" (wenyang, maintaining a balanced state).

One complete cycle of exhalation and inhalation is called a "breath" (xi). In Daoism, this is likened to the circular symbol of Taiji (○), which Buddhist patriarchs also refer to as the "circle symbol" (○). The pause between breaths is also considered part of the breath—Daoism calls it the Wuji (丶) within Taiji, while Chan Buddhism refers to it as the "dot within the circle" (丶), akin to the natural pause when an ox grazes.

If the mind (shen) fails to synchronize with the breath during respiration, this is called "unregulated" (butiao). It occurs when the primordial spirit (yuanshen) cannot command the primordial qi (yuanqi), causing spirit and qi to separate. Only when the mind and breath are fully integrated can it be considered true breath regulation. The commentary on the Huangting Jing (Scripture of the Yellow Court) states: "Exhalation is release, inhalation is intake—awareness must be maintained between breaths." Buddhism similarly speaks of "following along" (suishun), allowing the breath to flow naturally. Both emphasize the need for harmony between mind and breath. However, forcibly controlling the breath against its natural rhythm does not qualify as true regulation.

Even if the mind and breath are synchronized, if the practice proceeds arbitrarily without following the path of "true breath" (zhenxi, the innate respiratory rhythm), it still cannot be called proper regulation. Authentic breath regulation requires that the mind and breath move in unison—advancing together when it's time to advance, pausing together when it's time to pause, and traveling along the correct meridian pathways. These pathways are the Conception Vessel (renmai, the "Yellow Path") and the Governing Vessel (dumai, the "Red Path"). The primordial spirit and qi must circulate along these two vessels. Only then can one gather primordial qi, refine the Golden Elixir (jindan), enter the state of "embryonic breathing" (taixi, an advanced respiratory state), and attain great stillness (dading). This is what the ancients meant when they spoke of "insufficient refinement in cultivation."

Once, a disciple asked Master Dan Yang (a patriarch of the Quanzhen tradition): "I've practiced for many years—why do I still fail to perceive the great Dao?" The master replied, "Because your cultivation lacks refinement." Similarly, if one progresses too hastily along the path of true breath, the practice becomes restless and uncoordinated.

In cultivation practice, movement should be swift but not excessively so—moving too quickly is like floating on water without taking root. If thoughts and breath fluctuate like duckweed, the original spirit (Shen, innate consciousness) and Qi mechanisms will scatter and fail to coalesce. Though it may appear as if mind and breath are in harmony, true coordination has not yet been achieved.

Practicing too slowly also poses problems. Excessive slowness causes stagnation of Shen and Qi, either making their movement imperceptible or forcing reliance on tangible breathing to propel them. However, deliberately controlling the breath is even more inadvisable—once fixated on breathing rhythms, one easily incites "perverse fire" (disordered internal energy) and invites illness. As the ancients said, "It is not the breath that is refined," just as the Avatamsaka Sutra teaches that cultivation should proceed "neither too slow nor too fast," striking the perfect balance.

Lü Dongbin (the Pure Yang Perfected Being) described this natural, flowing state as "lightning piercing clouds, sun and moon racing, dragons soaring and tigers leaping." Yu Yu’wu emphasized that the "fire timing" (Huohou, energy regulation during cultivation) must be precise down to the finest degree to avoid errors in the "ninefold reversion of the Golden Elixir" (Neidan alchemical process).

On the essence of true breath (innate respiration): one must neither deliberately foster it—for sensing the breath means clinging to form—nor completely forget it—for total neglect loses its true nature. Fixating on "presence" or "absence" are both biases that disrupt the natural state. Authentic cultivation transcends the duality of being and nonbeing, wholly aligning with the patterns of the Dao. Each inhalation and exhalation may seem ordinary, but if not attuned to celestial timing (natural law), the Golden Elixir (cultivation attainment) cannot be perfected.

Perfected Being Ma Danyang revealed the crux: regulating breath is not about controlling nasal respiration—"regulation" (Tiao) is active adjustment, while "breath" (Xi) occurs spontaneously. In the higher state of neither inhaling nor exhaling lies a profound and deeper mystery.

This passage discusses the essential principles of breath regulation (tiaoxi) in spiritual cultivation, emphasizing the need to avoid two extreme approaches.

First, it clarifies that "fixed breathing" (dingxi) does not mean forcibly holding one's breath. Liu Haichan (a patriarch of Daoist internal alchemy, Neidan) stated that one should not mistake breath suppression for genuine breath regulation—counting breaths or mechanically following prescribed methods are not the correct approaches. Forcibly restraining the breath leads to agitation and disharmony, a practice associated with heterodox methods that violate the natural Dao. The true profound state is achieving a natural breathing rhythm that extends infinitely into the "boundless" (wuji).

The Chan (Zen) Buddhist saying, "Only when you can turn your body and exhale freely," conveys a similar meaning—only then can one truly grasp the essence of meditation. The term "Chan" (dhyana) consists of two characters: "Chan" (stillness of mind) and "Na" (regulation of breath), together signifying breath within stillness. Using the analogy of a walking stick: just as one relies on a cane to walk, cultivation relies on breath regulation to transcend worldly attachments and realize one's true nature. Without breath regulation, any claim of achieving meditative stability is merely empty talk of outsiders and ordinary people.

On the other hand, one must not neglect breath entirely. Liu Haichan said, "Focus the Qi to attain softness, and the spirit will long remain; the true breath comes and goes in natural ease," meaning one should not indulge in uncontrolled breathing like ordinary people. While the previous extreme was excessive control, this one is complete neglect. Unrestrained breathing leads to loss of awareness, making it equally impossible to harmonize Qi. The Chan saying, "Before reaching the end of water and mountains, one must first pass the time with companions," also conveys this—one must first master breath regulation before attaining the extinction of discursive thought.

So, what is the truly skillful method of cultivation? The ancients said, "There is a natural, innate fire (internal rhythm of practice); no need for firewood, charcoal, or forced effort." The Scripture of Ascension to Heaven and Attaining the Dao describes: When a practitioner turns inward in contemplation (neiguan), the true Qi naturally becomes pure and luminous, entering a state of indistinct chaos—where the six senses (eyes, ears, nose, tongue, body, and mind) are purified, the eight consciousnesses (Buddhist concept of mental functions) are empty and still, and the five aggregates (form, sensation, perception, mental formations, and consciousness) are all void. In this state, one attains the wondrous realm of the three primordial energies (Jing, Qi, Shen) and realizes the Dao. This aligns perfectly with Buddhist teachings.

After reaching this natural and stable state, one must continue refining it, advancing further even at the pinnacle of achievement. Buddhists call this "serene ease" (qing'an), where "ease" actually signifies harmony. The Buddhist terms "Dharma joy" (delight in the teachings) and "meditative bliss" (joy of absorption) both refer to this state of harmony brimming with infinite vitality. To grasp the principle of "harmonious emptiness" (chonghe)—the unity of stillness and harmony—is to grasp the true essence of cultivation.

This scripture expounds the "principle of harmonious interaction" (chonghe zhi li) in cultivation, which refers to the method of harmonizing innate Qi (the primordial life energy we're born with) and acquired Qi (the breath of daily life). When these two energies perfectly merge, practitioners enter a wondrous state resembling mild intoxication.

Multiple adepts have described this state: The Lingguang Ji (Collection of Spiritual Light) likens it to the disoriented yet cyclical awareness of a drunkard; the Cuixu Pian (Treatise of Emerald Emptiness) portrays it as a dissolution of flesh and bones into complete obliviousness; while Master Wang Chongyang describes it as the process of seeking carefree liberation and gradually entering meditative absorption. This realm resonates with Buddhist teachings such as the Avatamsaka Sutra's "subduing delusions through meditative power" and the Brahmajala Sutra's "practicing the unborn Dharma in unmoving suchness," demonstrating the ultimate convergence of Daoist and Buddhist highest realizations.

In genuine meditative absorption, though practitioners maintain subtle breathing (zhenxi, true breath), they perceive it as complete respiratory cessation. This "true breath" differs fundamentally from ordinary respiration: outwardly appearing as void yet inwardly circulating, it becomes the necessary passage to nirvanic stillness. By contrast, ordinary breathing binds beings to the cycle of birth and death.

When beginners first practice absorption, though aspiring to breathless stillness, they cannot yet achieve complete respiratory cessation. Only through prolonged cultivation can mundane breathing be fully transcended to enter authentic "great absorption" (dading). At this stage, one must relinquish attachment to both "being" and "non-being," even abandoning concepts of "emptiness" and "non-emptiness," to attain genuine voidness.

This realm surpasses all dualities of existence/non-existence and emptiness/non-emptiness. As the Zhonghe Ji (Anthology of Central Harmony) states: "Maintaining what seems present yet appears absent" reveals the profound mystery of true breath's operation. Only through this absolute voidness can practitioners ultimately return to their primordial true nature.

Master Wang Chongyang's teaching of "contemplating emptiness to return to emptiness" refers to attaining genuine emptiness through meditation, yet this emptiness is not lifeless void ("non-empty emptiness"). This principle aligns perfectly with the Buddhist concept of "the Tathāgatagarbha that is empty yet not empty."

If one clings to the "non-empty" state, one falls into the eternalist view (the mistaken belief in permanent existence). Conversely, if one clings to the "empty" state, one falls into the nihilist view (the mistaken belief in utter nothingness). True wisdom lies in maintaining awareness of emptiness within non-emptiness (illumination within stillness), and awareness of non-emptiness within emptiness (stillness within illumination). As the Buddhist sutra states, "The self-luminous radiance shines through past and present"—this state of empty-yet-non-empty is the genuine Tathāgatagarbha.

The essential point is "dual cultivation of stillness and illumination"—one must practice both tranquility and contemplation, ultimately transcending their duality. When immortals and buddhas discuss emptiness/existence or being/non-being, they're actually describing the meditative state where mind and breath become one: discussing mind-nature inherently includes breath, and discussing breath inherently includes mind-nature. Without mind-nature, breath cannot be pacified; without breath, mind-nature cannot be stabilized. Practitioners who cling to literal interpretations will fall into nihilism without attaining realization. Those who understand this principle grasp the unified essence of immortal and Buddhist cultivation.

Only those who awaken to true emptiness can genuinely regulate their breath. Without breath regulation, one can never enter profound stillness (da ding). This process is fundamentally about using the mind to pacify the breath—unstable breath reveals unsettled mind-nature. How then can one unite with the Dao? The lay Buddhist master Fu Dashi (of the Southern Dynasties) said: "Why six years snow-mountain austerity? Great stillness harmonizes qi and shen. When every moment holds one breath, the Great Dao reveals three vehicles." This precisely illustrates the principle.

Authentic practice requires both utilizing breath and transcending it—a state equivalent to "all dharmas return to One, yet the One returns to nowhere." The "cessation-contemplation samadhi" refers to true stillness where mental fluctuations cease and breath transcends inhalation/exhalation.

Crucially, one must fully attain cessation-contemplation before emerging from meditation. Premature emergence is called "elixir leakage" (zou dan) in Daoism and "demonic possession" (ru mo) in Buddhism—neither constitutes true emergence. Not only does this fail to manifest spiritual powers (shentong), but risks regression and downfall. Beyond the realm of spiritual powers lies the higher stage of returning to emptiness and merging with the Dao.

This passage discusses the supreme state of "extinguishing all life and death" in spiritual cultivation. When practitioners attain complete transcendence beyond life and death, entering and exiting meditative states at will, their spirit (Shen) becomes utterly unimpeded. No longer obstructed by the Six Dusts (form, sound, scent, taste, touch, and mental phenomena), such genuine spiritual powers enable one to traverse heaven and earth, possessing six penetrations, ten penetrations, or even countless billions of spiritual abilities—omniscient and omnipresent. This represents the ultimate state of returning to emptiness and merging with the Dao.

Regarding the concept of "medicine and fire," various interpretations exist: The first view holds that spirit (consciousness) is fire while Qi (vital energy) is medicine—using spirit to harness Qi constitutes refining medicine with fire. The second considers fire and medicine as fundamentally identical, where spirit and Qi are originally one. The third states that during collection it's called medicine, while during refinement it's called fire—both spirit and Qi may be referred to as either. In essence, these three interpretations share the same principle: using spirit to govern Qi. During collection, Qi returns to merge with spirit, their unified ascent and descent termed medicine; during refinement, spirit returns to the Qi cavity (Dantian), their blended circulation termed fire.

In cultivation terminology: "True lead" refers to the essential Qi (Jing-Qi) gathered and returned to the root within the body, while "true mercury" denotes the guiding spirit in the heart that coordinates this process. When mercury (spirit) contains lead (Qi), it's called true lead; when lead contains mercury, it's called true mercury. Most people fail to comprehend these subtle principles, hence Master Qiu Chuji's poetic instruction: "Travel together by day, rest together by night," illustrating the inseparability of spirit and Qi. Ultimately, all these teachings point to the harmonious fusion of these two substances.

Li Yuxi remarked: "Using spirit to harness Qi constitutes gathering medicine; making Qi unite with the talisman (spirit) constitutes applying fire"—both describing the principle of spirit-Qi unity moving and dwelling together. Therefore, whether describing medicine and fire as one substance or two remains equally valid. As the Primordial Heavenly Sovereign (Yuanshi Tianzun) declares in the Lingbao Duren Jing: "When this wondrous fusion of spirit and Qi merges with emptiness, the body of emptiness spontaneously manifests"—precisely conveying this truth.

This passage elucidates the profound mysteries of Shen (spiritual consciousness) and Qi (vital energy) in Daoist cultivation. The original text employs numerous metaphors to convey essential practice principles:

Practitioners must transcend the limitations of Yin-Yang's cycles of birth and dissolution, attaining the formless and imageless state to truly realize the Dao. Terms like "mercury," "fire," and "medicine" in the verses are not literal but represent ancient alchemical metaphors describing the subtle relationship between Shen and Qi. These two are fundamentally unified, hence their frequent pairing in cultivation texts.

The scripture uses celestial imagery: the sun symbolizes Shen while the moon represents Qi. Just as the sun and moon sometimes move in tandem, Shen and Qi follow interdependent rhythms. Shen itself is formless, yet seems to manifest during mental activity; Qi possesses form yet appears absent in its imageless state. Their union requires regulated breathing techniques - a process traditionally called "refining medicine with fire" in classical texts, without which their harmonization remains impossible.

Master Qiu Chuji emphasized: The celestial cycle follows specific pathways that cannot circulate without the mediating Qi. The text mentions the "Zi hour" (11 PM - 1 AM) when Shen-Qi ascends along the spine, and the "Wu hour" (11 AM - 1 PM) when they descend through the front, completing the circuit. Throughout the twelve two-hour periods (a full day), Shen and Qi move and rest in perfect synchrony.

"Empowering the crown" refers to raising original Jing (primordial essence) through the Governing Vessel to nourish the crown - the method of gathering medicinal energy. Interestingly, Buddhist bodhisattvas perform similar crown empowerments before teaching, revealing shared underlying principles. Yet many monks misunderstand this cultivation essence, reducing Buddhist teachings to superficial doctrine because they fail to truly transcend desire and attain pure detachment.

The "three pairs" denote the three key passes - Wei Lü, Yu Zhen, and Jia Ji - each having dual channels (the Yellow and Red Pathways), hence the name. "Silent transition" describes Shen-Qi's unobtrusive movement through these strategic junctures.

This passage explains the method of focused concentration in spiritual cultivation. Ancient practitioners likened this state to the relationship between "fire and medicine," which essentially refers to the harmonious interplay between spirit (Shen) and vital energy (Qi). Simply put, mastering the key principle of "gathering the spirit in the Dantian (energy center)" is the essence of both Daoist and Buddhist cultivation.

Someone might ask: Why did the ancients use the metaphor of a cat stalking a mouse to describe cultivation? The answer is that this analogy vividly illustrates using one's innate nature to control emotions and guiding Qi with focused awareness. Just as a cat remains perfectly still with all four paws grounded while watching its prey, this represents the state of single-minded concentration—what Lü Dongbin called "fasting and waiting for the rise of Yang energy." The cat's intense gaze at the mouse serves as a reminder for practitioners to maintain unwavering focus and not miss the crucial moment.

The Yinfu Jing states that "the key lies in the eyes," while the Śūraṅgama Sūtra records the Buddha telling Ānanda, "If one does not understand the functions of mind and eyes, one cannot subdue afflictions." The Buddhist concept of the "Treasury of the True Dharma Eye" conveys the same meaning—both traditions emphasize the importance of focused observation. In this regard, the cultivation methods of Daoist immortals and Buddhist practitioners converge.

The state of "profound stillness and immobility" is like knowing that whiteness (Yang energy) will emerge from blackness (Yin energy), hence one guards the darkness while awaiting the appearance of Yang. Here, the "masculine" represents the original essence (Jing) and Qi within kidney water, while the "feminine" symbolizes kidney water itself. This condition resembles the Buddha's six years of snow mountain asceticism, where he sat in stillness day and night to eliminate the "six thieves" (desires arising from the six senses—eyes, ears, nose, tongue, body, and mind). One must maintain uninterrupted right mindfulness, immediately dispelling any distracting thoughts when they arise.

Such focused concentration is particularly crucial during the Daoist "Ten-Month Pass" (the critical phase of refining Qi into Shen). The Sūtra of Perfect Enlightenment similarly teaches to "constantly maintain right mindfulness while sitting in meditation." Thus, both Daoist and Buddhist traditions employ the cat-and-mouse analogy to underscore the vital importance of single-pointed attention in cultivation.

This scripture employs the metaphor of a cat catching mice to elucidate the cultivation of true Yang elixir. The cat represents the practitioner, while the mice symbolize the true Yang (primordial Qi) within the human body. In the initial stages of practice, it resembles the cat actively pursuing mice—this corresponds to the stage of "deliberate effort" (youwei gongfu). However, after passing this phase, one must attain the state where both cat and mice are forgotten: neither deliberately gathering the elixir nor forcefully capturing it. Only then can one truly attain the Dao.

It further explains that just as mice appear at specific moments, the emergence of true Yang follows its natural rhythm. If one fails to recognize the signs of true Yang's manifestation, it's like a cat guarding an empty mouse hole. Even if one recognizes these signs but doesn't understand the proper timing for gathering the elixir, they'll merely sit in vain—again resembling a cat watching an empty hole. These are the states of "deluded cat" that practitioners must avoid in cultivation.

Regarding "harmonious emptiness" (chonghe): This refers to the profound state contained within the breath. When primordial Qi (the innate energy) harmoniously merges with acquired Qi, it generates a misty vitality that fills heaven and earth. This state transcends the limitations of ordinary breathing—neither obstructed by respiration nor bound by the rising and falling of breath. True harmonious emptiness manifests as a subtle equilibrium where breathing seems both present and absent.

There are two crucial stages in cultivation: During the lesser celestial cycle (initial foundation-building), it's called "bathing" (muyu), while in the greater celestial cycle (advanced practice), it's termed "guarding the center" (shouzhong). The essence of "guarding the center" lies in neither clinging to tangible methods nor sinking into nihilistic emptiness, but maintaining the natural Middle Way. The wondrous application of this harmonious emptiness requires transmission from a true master. As Perfected Liu Changsheng taught: "Nourish the spirit (Shen) by harmonizing the breath." Ordinary people don't comprehend the true principle of breath regulation—it fundamentally means achieving this state of harmonious fusion in breathing.

Master Wang Chongyang (founder of the Quanzhen tradition) said: To fully master breath regulation and stabilize Qi is not inherently difficult—the essential point lies in understanding how to nurture Jing (essence), Qi (vital energy), and Shen (spirit) into harmonious equilibrium. He further taught: When spirit and breath achieve perfect harmony, one may refine the Golden Elixir (Jindan). Ordinary people often fail to grasp this principle, unaware of the dangers to guard against in cultivation. The peril to avoid is precisely "disharmony"—for where disharmony arises, one risks straying into forceful manipulation through heterodox methods, thereby violating the true meaning of "wondrous being within sublime emptiness" (zhenkong miaoyou), making genuine harmony unattainable.

Harmony enables fusion; disharmony prevents it. These two phrases encapsulate the essence of the previous four statements. Whether gathering the medicinal ingredients (referring to internal Jing and Qi), refining the elixir, or navigating cultivation's intense phases ("battleground practice"), this harmonious state must be maintained—this constitutes the shared gateway of Daoist and Buddhist cultivation. Similarly, during quiescent practice ("guarding the city"), crystallizing the Golden Elixir ("forming the embryo"), and nurturing the sacred embryo ("gestating the embryo"), such harmonious balance remains indispensable.

Master Liu Changsheng (one of the Quanzhen Seven Masters) observed: During the hundred-day foundation phase (refining Jing into Qi), seek the harmony of Kan (Water) and Li (Fire) coupling; in the ten-month embryo-nurturing phase (refining Qi into Shen), maintain the harmony of breath and spirit.

Someone asked: What state constitutes true harmony? The answer: It must be perfectly centered—partiality toward form and appearance deviates from the Middle Way. It must be precisely measured—neither excessively forceful nor overly lax in intention. It must be neither rushed nor sluggish—haste breeds agitation, while delay causes stagnation. It must resemble both presence and absence—neither indulging in utter emptiness nor clinging to concrete existence. This is the realm of "empty yet not empty, not empty yet empty." Only by avoiding these eight deviations can true harmony be achieved.

Regarding how to realize this harmonious state: The mind and breath must accompany each other like husband and wife walking side by side ("heart-breath mutual reliance"), with Yin and Yang energies perfectly fused ("the subtle convergence of the Two Fives"). During daytime practice, intention and breath must synchronize—neither leading nor lagging. Leading risks straying into Daoist gymnastics (daoyin) techniques; lagging fails to guide Qi's movement. This subtle calibration is most challenging and demands utmost care—hence Buddhism likewise emphasizes "accordance" with natural flow. During nighttime stillness, maintain an appropriate distance of "intimacy without attachment."

The passage discusses essential points and potential dangers in cultivation practice.

During practice, breathing should remain natural and balanced—neither too forced (constrained) nor too lax (scattered). Maintaining this perfect equilibrium is the true state of meditative absorption (samadhi). As the Avatamsaka Sutra states, "the genuine experience within right concentration" refers precisely to this ideal harmonious state.

Throughout cultivation, one must remain vigilant against various hazards. Here are some common ones:

First is the timing of "gathering the medicine." Authentic "medicine" (referring to the vital Jing and Qi required for cultivation) emerges at specific moments. Missing this window means failing to collect genuine vital energy—completely distinct from the baseless claims about gathering medicine made by worldly people. If the timing is wrong, any so-called medicine collected will be false and utterly useless for alchemical refinement. One must act precisely when the vital energy manifests.

Next is the firing process (huohou) during the celestial cycle (zhoutian) circulation. The movement of true Qi must follow specific meridian pathways (the Yellow and Red Paths). If the Qi is recklessly directed without adhering to the correct routes, it cannot be refined in the dantian (the alchemical furnace and cauldron), which poses grave danger.

Equally crucial is mastering the firing intensity. Applying fire (increasing mental focus) requires perfect balance—neither stopping short of the required position nor exceeding the proper measure. Withdrawing fire (reducing focus) likewise demands precise moderation. As the Huangting Jing Commentary states, "both inhalation and exhalation must return to the dantian." Insufficient firing fails to nurture true Qi, while excessive firing risks losing control of the energy. As Chen Niwan warned: "The gathering has its method, the application its measure; the dosage must be exact."

These are critical junctures requiring utmost attention in cultivation. The slightest misstep can undo all previous efforts.

The cultivation process contains numerous dangers that require careful vigilance. Subtle methods like balancing water and fire (regulating Yin-Yang energies within the body), the techniques of extraction-addition and advance-retreat (referring to methods of adjusting internal Yin-Yang energies), and the states of "bathing and intertwining" (describing the fusion of Yin and Yang during practice) all demand constant awareness of potential risks.

The venerable Bai Yuchan warned: During the warming-nourishing phase (the later stage of cultivation where refinement occurs), lack of proper caution may lead to the loss of Mercury (symbolizing the original spirit, Shen) and dispersal of Lead (symbolizing the original essence, Jing). Continuing the fire-timing (control of internal energy) after it has reached completion will damage the internal elixir (Neidan). Master Cui Xifan stated in the Mirror for Compounding the Medicine: When the fire-timing is sufficient, one must stop—persisting further harms the elixir. Zhongli Quan also emphasized: Once the elixir is formed, further application of fire-timing is unnecessary; forcing it will inevitably damage the medicine. Zhang Boduan gave even graver counsel: In alchemical practice, one must know when to stop—greed for progress will ultimately lead to failure.

When gathering the elixir (the refined essence obtained through cultivation) to break through the passes, if the energy gates (key points in the body's meridian system) are not truly open, the medicinal potency will dissipate. This occurs when the initial gathering was mistimed—though the elixir may appear complete, its power remains weak. Unable to grant longevity or penetrate the barriers, its energy scatters, leaving the practitioner no different from ordinary people.

When first opening these energy gates, hesitation in swiftly passing through the Three Barriers (critical junctures in cultivation) will undo all previous efforts. This demands total concentration and vigorous advancement—the slightest delay causes the fire-timing to regress.

Even after traversing the Three Barriers, danger persists at the Magpie Bridge (symbolizing the connection between the Governing and Conception Vessels, represented by the southern Vermilion Bird as the guiding mind). Here, success depends entirely on the mind's ability to guide primordial Qi (vital energy)—the slightest misstep brings complete failure.

After crossing the Magpie Bridge, the process of "ingesting" and returning the elixir to the Yellow Court (storing it in the Dantian, the energy center) becomes like treading on thin ice. Wang Chongyang described this as walking atop a slender pole—the slightest error plunges one into emptiness.

When cultivating the Yang spirit, any remaining traces of Yin impurity or demonic obstructions during the nascent spirit-embryo stage pose extreme peril. Forcibly projecting the spirit before reaching the proper stage of spiritual liberation is dangerous, but failing to emerge successfully when the time comes is equally hazardous. The transitions between meditative absorption and emergence are fraught with crisis. Only by overcoming these successive barriers can one transcend the cycle of life and death.

This passage elucidates the crucial concept of "bathing" (muyu) in Daoist cultivation and the underlying principles of immortality practice.

The method for cultivating immortality must align with the Dao (the Way), ultimately reaching the realm of emptiness to avoid peril. While all worldly phenomena are subject to destruction, only emptiness remains eternally indestructible.

Regarding the meaning of "bathing," this represents the core method for refining essence and vital energy (Jing and Qi), belonging to the secret transmission of fire regulation techniques in internal alchemy (Neidan). Due to its supreme importance that cannot be explicitly stated, the metaphor of "bathing" is employed. Within the twelve earthly branches, the positions of mao (卯) and you (酉) symbolize critical moments of life-death transition, thus serving as analogies for pivotal junctures in cultivation. The Buddha also used bathing metaphors in his teachings, demonstrating the shared principles between immortals and buddhas in their cultivation practices.

During the lesser celestial cycle (xiaozhoutian) practice, this is called "hidden correspondence" (yinfu) – secretly aligning with celestial mechanisms. At this stage, one doesn't forcibly control the fire phases but allows natural fire regulation to harmonize with cultivation rhythms. In the greater celestial cycle (dazhoutian) stage, it's termed "body-refining samadhi fire" – using the samadhi true fire to refine the physical form.

The text employs the twelve life stages of the Five Phases (wuxing) – birth, bathing, capping, etc. – to illustrate the cyclical nature of life and death. For instance, fire is born in the yin position while metal is born in the si position, demonstrating how yin-yang life-death transformations operate – where one element dies, another is born; where one is born, another dies. Practitioners precisely grasp these mysteries of life-death transition, using the bathing method to symbolize crucial cultivation points.

The conclusion reveals that heaven, earth, and yin-yang follow the same principles as humans – where there is birth, there must be death, and within death emerges new life. Golden Elixir (jindan) cultivation applies these natural patterns to oneself: just as fire's birth position is yin and its second stage is bathing, so too does cultivation progress through these corresponding critical junctures.

This scripture reveals the profound mystery of the "Mao-You Bathing" (卯酉沐浴) practice in Daoist Neidan (internal alchemy) cultivation. The term "bathing" here does not refer to literal washing, but rather to a special phase for regulating the fire intensity during cultivation.

The Mao period (5-7 AM) and You period (5-7 PM) correspond respectively to due east and due west in directional alignment, forming the "Four Cardinal Points" (四正) together with Zi (due north at midnight) and Wu (due south at noon). Ancient adepts discovered that Metal (corresponding to the western You position) and Wood (corresponding to the eastern Mao position) in the Five Phases (五行) follow special growth patterns during these periods. Metal reaches its growth peak during the Si period (9-11 AM) and undergoes bathing at noon, while Wood peaks during the Hai period (9-11 PM) with bathing at midnight.

Master Cui (a renowned Tang dynasty Daoist) disclosed this thousand-year secret in his work Mirror for Entering the Medicine (入药镜). Wang Chongyang (founder of Quanzhen Daoism) also spoke of the cultivation formula "harmonizing Zi-Wu while connecting Mao-You," and Bodhidharma's teaching of "six periods in one session" both point to this same principle.

Many mistakenly believe "Mao-You Bathing" means completely ceasing cultivation—this is a misunderstanding. In truth, it represents an esoteric method for fire regulation that requires authentic transmission from a genuine master. Ordinary observers see only surface phenomena and rashly conclude that cultivation should stop during these periods. Only truly realized adepts understand these moments conceal profound mysteries requiring special methods to adjust the fire intensity.

When sages speak of "suspending fire regulation," they actually mean applying special numerical principles to control the fire—not truly stopping cultivation. These are deliberately veiled teachings transmitted through coded language, requiring guidance from an enlightened master to comprehend their true meaning.

The Record of the United School of Immortals and Buddhas primarily discusses the true meaning of "muyu" (bathing) in Daoist cultivation—referring to the quiet nurturing phase where intentional practices are temporarily suspended—while refuting certain misconceptions.

The Perfected Wei Boyang states in the Cantong Qi that during cultivation, one should seal the three apertures (ears, eyes, and mouth) to allow the internal Qi to circulate naturally. The Perfected Chen Niwan and Master Lu Ziye, in their commentaries on the Wuzhen Pian, both mention that during the mao (5-7 AM) and you (5-7 PM) periods, one should refrain from deliberately "stoking the fire" (consciously guiding Qi) and instead let the true Qi naturally permeate—this reveals the profound mystery of "muyu." These teachings all hint at the esoteric methods of cultivation.

The text points out that some practitioners have misinterpreted the cryptic language of past sages, mistakenly believing that the mao and you periods require complete cessation of fire-tending (cultivation techniques). Some have even fabricated spurious texts to mislead others. In truth, "muyu" does not mean entirely abandoning fire-tending but rather temporarily suspending deliberate methods in favor of more subtle practices. The author cites the words of revered masters like Wang Chongyang (Chongyang Zhenren), Bai Yuchan, Zhongli Quan, and Xue Daoguang to demonstrate that authentic "muyu" refers to the vigilant, quiet-nurturing skill of guarding against dangers throughout the entire cultivation process—not merely during specific months in spring and autumn.

Finally, the text emphasizes that genuine cultivators should understand the "ten-month gestation period" (a metaphor for the complete cultivation cycle) requires maintaining the "muyu" state throughout. This is the orthodox transmission. Those who rigidly adhere to practicing "muyu" only during two seasonal months hold a partial and erroneous view.

This passage primarily discusses the timing of "muyu" (a special phase in Daoist cultivation referring to regulating the firing process and relaxing body-mind) in Daoist practice. Ancient practitioners often designated the second and eighth lunar months as periods for muyu, but the author clarifies this is actually metaphorical.

When practicing the Grand Celestial Circuit (advanced Neidan/internal alchemy techniques), the application of firing process doesn't require strict hourly divisions like in the Lesser Celestial Circuit (basic techniques). Authentic cultivation should be continuous without interruption during these months. The text cites Master Ziyang (the renowned Northern Song Daoist Zhang Boduan) and Shi Xinglin (a Song dynasty Neidan master) to illustrate that muyu timing shouldn't be rigidly tied to specific months or hours.

The author employs the metaphor of pregnancy: just as a mother-to-be cannot neglect fetal nourishment for two months, practitioners shouldn't suspend cultivation during these months. Such interruption would lead to dissipation of Shen (spirit) and Qi (vital energy), violating Daoist principles. Throughout the "Ten-Month Barrier" (metaphor for the gestation-like cultivation period), continuous firing process is essential to transform Qi into Shen, ultimately achieving the Yang Spirit (advanced realization in cultivation).

This passage emphasizes the flexibility required in managing the firing process, warning against rigid adherence to superficial temporal regulations that could mislead future practitioners and even destroy nearly accomplished Neidan work.

This passage elucidates the core principles and concrete methods of Daoist cultivation, integrating the wisdom of immortal Dao (Xiandao) and Buddhist teachings.

It first emphasizes that these teachings dispel ancient confusions and reveal timeless mysteries, directly connecting to the orthodox principles of celestial immortality (Tianxian Zhengli). Later practitioners who receive transmission from celestial masters or divine teachers—particularly those inheriting the lineage of Qiu Chuji (the Eternal Spring Master, Changchun Zhenren)—must validate these truths to truly comprehend the immortal path. Quoting Zhang Ziyang, it states that those who propagate the true Dao (Zhengdao) will not fall into hell, as the teachings preserved in scriptures can liberate the Three Masters (referring to the masters of transmission, protection, and realization).

The text then elaborates through two poems:

The first poem explains that the foundation of the Dao (Dao) lies in the character "One" (Yi). The Dao originates from the formless and imageless "Wuji" (Non-Ultimate), from which emerges the manifest "Taiji" (Supreme Ultimate, represented by "One"). From "One" arise the two energies of Yin-Yang, which then transform into the Three Treasures (Jing, Qi, Shen)—essence, vital energy, and spirit—further giving rise to the myriad transformations of existence. In cultivation, the "mind" (Xin) is the guiding force: refining essence into Qi (Lianjing Huaqi) and refining Qi into spirit (Lianqi Huashen) both require the mind's direction. At the stage of refining spirit to return to emptiness (Lianshen Huanxu), one must attain the wondrous state of effortless action (Wuwei), yet fundamentally, all stages rely on the mind's function.

The second poem employs metaphors to illustrate the cultivation process: Metal (symbolizing true Yang-Qi) arises from the Kidney-Water (Black Lead, Heiqian); the Wood-nature (symbolizing the primordial spirit, Yuanshen) returns from the Heart-Fire (Bing-Ding). The elixir (Neidan, internal alchemy) forms when spirit and Qi condense in the Dantian (Mysterious Valley, Xuangu). The final state is described as "the stars encircling the Northern Dipper (Gangtai) illuminating the Jade Stream (Bixi)," depicting the internal Qi circulation resembling the rotation of the Big Dipper and the fusion of spirit and Qi. Ultimately, one must cultivate to the boundless, undifferentiated highest realm—the "Infinite Primordial North" (Wuyin Yangbei Jing).

The text frequently employs Neidan terminology: "Mysterious Valley" (Xuangu) refers to the lower Dantian; "Jade Stream" (Bixi) signifies the saliva in the mouth; "Northern Dipper Platform" (Gangtai) symbolizes the Big Dipper, all corresponding to internal bodily loci and metaphors in cultivation. The core of practice lies in the union of spirit and Qi, refining Jing, Qi, and Shen to ultimately return to the Dao’s formless emptiness.

This scripture elucidates several key concepts and states of attainment in Daoist cultivation, employing metaphors and classical allusions to illustrate the practice process.

The terms "boundless expanse" and "primordial chaos" describe states of infinite vastness and the undifferentiated beginning, referring to the cultivated state of empty clarity—akin to the Buddhist notion of Nirvana that transcends birth and death. Sitting alone in the "Yellow Court" (referring to the middle Dantian, the body's energy center) while accompanied by "formless subtlety" signifies the practitioner entering a realm of absolute independence beyond dualistic distinctions, resonating with the Buddhist pursuit of stillness and cessation.

The text then employs the allegory of Xu Jingyang (a renowned Jin Dynasty Daoist) slaying the flood dragon. Centuries ago, Xu subdued demonic forces in Changsha, and now, twelve hundred years later, the practitioner returns to this symbolic stage—not to vanquish a river serpent, but to sever the "flood dragon essence" (representing base desires or turbid Yin energies) within the kidney water. The "subtle aperture" denotes the Mysterious Pass (a crucial point in cultivation), while "Qi reopens" signifies the ceaseless generation and circulation of primordial energy.

"Alchemical coagulation in the jade cauldron" depicts the Golden Elixir solidifying in the Dantian, mirroring the golden furnace and jade vessel of ancient alchemy. When True Yang (primordial Yang energy) merges with True Nature (inherent essence) to form the elixir, a rushing wind sound arises behind the ears—a portent of the Great Medicine's maturation. "Fire subdued in the golden furnace, breath settles like an embryo" describes the practice of stabilizing spirit and breath; when the breath becomes as tranquil as an unborn child, the practitioner attains abiding spirit-breath unity, ultimately reaching the extinction samadhi (a profound meditative absorption).

The passage concludes by revealing that this method ultimately transcends distinctions between "utility" and "futility." Through the "ten-month gestation" (symbolizing prolonged cultivation), one progresses from being to non-being, realizing the deathless realm of absolute stillness. The closing lines carry double meaning: they urge seekers to faithfully uphold orthodox teachings while emphasizing that true realization depends solely on personal practice and verification.

The path of cultivation requires unwavering faith and a pure mind, with each step practiced meticulously—no one else can do the work for you. Wu Taichu (religious name Taichu, sobriquet Jianchu, younger brother of Wu Zhenyang) posed six essential questions.

The first question: Where does genuine cultivation truly begin? The answer lies in the immortal tradition’s core practice of refining yang essence (the body’s innate energy) into primordial qi (original vital energy). Daoist cultivation first gathers scattered primordial jing (essence) and returns it to its original state as primordial qi, while Buddhism generally emphasizes transcending the realm of desire through abstinence. Both traditions fundamentally start with severing lust—without this foundation, cultivation becomes empty, and upon death, one risks falling into endless cycles of rebirth, unable to escape the six realms (the six forms of existence in Buddhist cosmology).

Those who steadfastly cultivate detachment are called "pure practitioners of Brahmacarya"; the attainment of this state is called "pure Brahma-virtue," the true basis for transforming consciousness and entering meditative absorption. Notably, among Buddhist traditions, only monks in the Zhejiang region occasionally discuss severing lust, a teaching passed down from the Tiantai master Zhiyi (whose elder brother Chen Zhen once studied under Zhang Guolao).

Young people, with their vigorous qi and blood, possess abundant yin-yang energies (lead and mercury, symbolic of vital forces), allowing rapid vitality and swift progress in cultivation. When yang energy arises, it must be gathered (collecting energy) and refined (transforming energy) at the right moment—this critical juncture is called "the birth of the single yang," occurring at midnight (11 PM–1 AM), when yang energy first stirs. This principle is summarized as "only when there is medicine can the fire be kindled" (cultivation requires sufficient internal energy).

Zhongli Quan, the immortal master, once said: The rarest and most precious opportunity is to begin cultivation in youth, as the foundation remains intact and results come quickly—perseverance for three years can lead to great attainment. Next is middle age, where one must first replenish deficiencies before cultivation, reversing aging to transcend the ordinary. For the elderly, whose essence and qi are depleted—like lead and mercury running low—cultivation becomes far more difficult.

History records many eminent Daoists who encountered enlightened masters at age sixty-four: Lü Dongbin met Zhongli Quan at sixty-four, Bai Yuchan met Chen Niwan at sixty-four, and Ma Ziran met Liu Haichan at sixty-four. Liu Langranzi also met his master at sixty-four. Even more remarkably, during Emperor Ling of Han’s reign, Liu Kuan abandoned his high-ranking position as Minister at seventy-three to study under Master Qinggu and succeeded. The Cuixu Pian states that cultivation’s challenges differ for young and old, while Ma Danyang (one of the Quanzhen Seven Masters) emphasized that sincere devotion to the Dao transcends age.

When one reaches the age of sixty, it is time to promptly engage in the dual cultivation of nature and life (referring to physical and spiritual refinement), not waiting until the body has completely declined to begin. The key to cultivation lies in grasping the cyclical patterns of movement and stillness. If one's actions are sluggish, one should actively guide them like striking bamboo to play the qin (a metaphor for cultivation methods), employing the method of "summoning the turtle and calling the phoenix" (a Daoist term denoting the mobilization of Yin and Yang Qi within the body). When Yin Qi reaches its extreme, it naturally transforms into Yang Qi, at which point one can gather the precious energy needed for cultivation.

The core teaching of Wuzhen Pian (Awakening to Reality) is this: if the mind is unsettled, it cannot produce the "medicine" (a Neidan term referring to the transformative energy of Jing, Qi, and Shen). Yuqing Jinsi Miwen (Secret Text of the Golden Casket from the Jade Purity) also emphasizes this principle. Master Wang Chongyang (founder of Quanzhen Daoism) taught that in a state of pure Yin, one must use "fire timing" (a cultivation term for the regulation of intention) to refine and stimulate Yang Qi, allowing the "divine illumination" (the numinous awareness of one's true essence and primordial Yang) to manifest naturally.

Long Meizi (a Song Dynasty Daoist) similarly proposed that just as a windwheel's rotation generates "true lead" (a Neidan term for innate primordial Qi), movement arises only after extreme stillness. These teachings all point to the necessity of preparation before the opportune moment arrives, enabling the production of "medicine" for cultivation.

In Lingbao Bifa (Complete Methods of the Numinous Treasure), Zhongli Quan (one of the Eight Immortals) explains that cultivation in later years must first rescue the weakened body before proceeding to replenish it. From small achievements, one accumulates medium successes, ultimately reaching the state of rejuvenation and prolonged earthly existence. These profound celestial mechanisms for beginning cultivation are largely unknown to the world. Nowadays, people often claim that aging precludes cultivation because they fail to understand this truth.

Master Wang Chongyang said: "If one can fully comprehend this principle, they may turn to cultivation immediately—the path to Penglai, the Isle of Immortals, awaits amidst the colored clouds for those destined to find it." I hold that as long as one still breathes, cultivation remains possible. Each breath is transformed from primordial Qi; the presence of breath signifies the persistence of primordial Qi, which is the fundamental basis for longevity. Ma Danyang (one of the Quanzhen Seven Masters) also taught: "As long as the breath continues, the spirit can stabilize. First, one must subdue the 'monkey of the mind and horse of the will' (a metaphor for distracting thoughts), and naturally, nature and life will take root."

Huangting Jing (Yellow Court Scripture) records that even at 120 years, one may still reverse aging. Patriarch Wang Chongyang stated: "Even starting at a hundred years is not too late—the crucial factor is the transformation of the heart." Chen Niwan (a Song Dynasty Daoist) pointed out: "To prolong life and rescue the body from decline, one must sever lust and other heterodox paths." There are ancient examples of individuals cultivating the Golden Elixir at eighty. Chen Niwan further said: "For true earthly immortality, one must employ fire timing to refine the divine elixir." Even Laozi (Lord Lao the Most High) declared that he continued cultivating even with white hair.

This scripture conveys through the words of numerous Daoist perfected beings the principle that cultivation knows no age and one should practice diligently without delay.

The Celestial Worthy of Primordial Beginning (Yuanshi Tianzun, the supreme Daoist deity) first created heaven and earth, establishing the kalpic cycles. After enduring and surviving each cosmic destruction, he would initiate a new creation. The Great Lord of the Dao (a high-ranking Daoist divinity) manifested during the fourth kalpa, and by the fifth kalpa had differentiated into Lord Lao (Taishang Laojun, one of the Three Pure Ones). Having traversed five kalpas, he became known as "the Elder," appearing with white hair as his emblem. When Lord Lao descended to be born into the Li family, he similarly manifested with white hair, demonstrating that cultivation is never too late to begin—even in advanced age one can achieve perfection, provided one practices with diligence.

Master Ma Danyang (a Quanzhen patriarch) only began cultivation at age sixty-nine. When others said it was too late, he replied that it's never too late to practice. At eighty-four, when asked why he started so old, he answered that cultivation remains possible as long as breath continues—the key lies in calming the heart. Bai Yuchan (a Southern Song dynasty Daoist) maintained a youthful countenance even at ninety, further proving that advanced age is no barrier to practice.

Immortal Elder Ge (Ge Xuan) at sixty worried about falling into the three evil rebirth paths. Wang Chongyang (founder of Quanzhen) lamented at fifty-two how swiftly time passes—even living to seventy would grant but few days, and losing human form means eons of suffering. Liu Langran warned against waiting until old age to cultivate, while Ma Danyang emphasized the urgency—our vital existence hangs by a breath; should it cease, we return to dust. One must awaken quickly to safeguard Jing (essence), Qi (vital energy), and Shen (spirit).

The scripture admonishes the elderly not to use age as excuse, nor the young to presume they can indulge now and cultivate later. Zhongli Quan (one of the Eight Immortals) observed that each year diminishes what remains; Ma Danyang calculated that seventy years amounts to merely twenty-five thousand days—each passing day like the setting sun. He added that few throughout history reached seventy, while Zhang Ziyang (a Northern Song Daoist) warned against letting life's candle be extinguished by the wind, for falling into the six rebirth paths leaves no room to blame heaven.

These are the earnest exhortations from immortals throughout the ages urging people to practice without delay. Those who encounter such teachings of cultivation should understand this profound truth.

This passage discusses the timing and methods of practicing Neidan (internal alchemy), a Daoist cultivation technique. Ordinary people experience active Jing (essence), Qi (vital energy), and Shen (spirit) during daytime while resting naturally at night. Practitioners should follow this rhythm, choosing nighttime as their primary cultivation period.

The accomplished adept Yu Yuwu observed that after prolonged practice, the distinction between dreaming and wakefulness disappears—consciousness remains alert even during sleep. Xia Yunfeng similarly noted that when the appointed cultivation hour arrives, practitioners naturally awaken even from dreams. Patriarch Lü Dongbin (the Pure Yang Ancestor) taught: "When Jing and Qi stir, cultivate; when stillness prevails, rest."

The author shares his personal experience during a hundred-day retreat in the spring of the Wanli Renyin year (1602): The first month served as an adjustment period, while the second month saw intensive practice. When internal Jing and Qi became active, his Shen naturally became aware, initiating Zhou Tian circulation (a Neidan term referring to the cyclical movement of essence and energy through the body). This confirmed the Buddha's enlightenment upon seeing the morning star, aligning with ancient immortals' descriptions like "gazing southward from the Northern Dipper" and Chan masters' sayings about "dwelling within the Big Dipper."

As practice deepened, nightly Zhou Tian cycles increased gradually from three to five times, eventually reaching over ten continuous circulations throughout the night. This continued until Jing fully transformed into Qi, at which point sufficient "fire phasing" (cultivation intensity) would produce clear signals to cease practice. Ma Danyang (a Quanzhen patriarch) advised conducting such cultivation secretly, unknown to others.

Within approximately two months (totaling three months including preparation), the "Great Medicine" (a Neidan term for cultivation achievement) could be refined. Wang Chongyang (founder of Quanzhen Daoism) taught: "During sleep, control the monkey-mind and horse-will (restless thoughts); while awake, continue gathering primordial Qi (jade mushrooms)." This hundred-day work can only be understood through personal experience.

The author mentions his teacher Cao Huanyang, who cultivated diligently at age thirty with vigorous spirit and nightly practice, unburdened by worldly affairs. He completed the fire phasing in under fifty days and harvested the Great Medicine within five—an example of dedicated practice yielding swift results. At advanced stages, extraordinary sensations manifest: golden light flashing from the eyes, nasal twitching, wind sounds behind the ears, and bird calls at the back of the head.

This passage discusses the crucial signs and key points in cultivating the Golden Elixir (Jindan), the core energy of Daoist internal alchemy (Neidan) practice.

When practitioners hear the clamorous cries of white egrets in the void behind their heads during meditation, this signals the imminent emergence of the Great Medicine. Similar spiritual experiences are described in Buddhist scriptures as the "Vulture Peak" or "Magpie Nest Crown Pouring." The body manifests six distinct reactions: the movement of a fiery pearl (representing condensed Jing-Qi energy) ascending and descending in the Dantian (energy center), corresponding to the six types of vibrational responses mentioned in Buddhist texts.

When this fiery pearl naturally surges through the Three Passes (key acupoints at the coccyx, thoracic spine, and jade pillow), it flows as effortlessly as a horse following a familiar path. Ancient adepts documented sensations like bladder warmth and kidneys bubbling like boiling water - all signs of attaining the Golden Elixir. This demonstrates that while the celestial immortality path of the Golden Elixir is unique, it shares common ground with Buddhist cultivation.

The text emphasizes the critical importance of precisely timing the practice's commencement and acquiring authentic Yang Jing (essential yang), Yang Qi (yang energy), and Yang Shen (yang spirit) - pure yang energies. Failure to do so risks straying into heterodox paths of Yin Shen (impure spiritual forms). Special attention is given to mastering the initial stages.

Regarding the pivotal "fire cessation" (Zhi huo) technique - when the Small Heavenly Cycle (foundational practice) completes and the elixir matures, conscious guidance must cease. This doesn't mean abandoning practice altogether, but rather transitioning from deliberate methods (youwei) to the natural spontaneity (Wuwei) of the Grand Heavenly Cycle (advanced practice). When the Great Medicine no longer dissipates, forceful mental guidance becomes unnecessary, and the practitioner should employ the Wuwei firing process of the Grand Cycle to refine true Qi.

This scripture discusses the critical timing and importance of "zhi huo" (ceasing the fire) during Neidan (internal alchemy) practice. The concept of "zhi huo" (stopping the intentional guidance of cultivation heat) has different requirements in the microcosmic and macrocosmic orbit practices. One must maintain the "fire" until the elixir (internal alixir) matures, only stopping when signs of "huo zu zhi hou" (the omen of sufficient Qi) appear—this marks the successful refinement of the elixir.

The immortal Ge Hong (a renowned Daoist of the Eastern Jin Dynasty) once said: To preserve the physical form and nurture the Shen (spirit), the most crucial practice is safeguarding the Jing (essence). However, if one fails to cease the fire after the elixir is complete, though they may attain longevity by maintaining the Jing in the Dantian (energy center), they will remain bound to the mortal body, unable to transcend the cycle of life and death.

Those who truly refine the "da yao" (supreme internal elixir) could become transcendent sages. Yet some, due to insufficient cultivation in past lives, only seek longevity, wealth, and worldly comfort in this life. Thus, the immortal masters can only fulfill their desire for longevity. As Chen Tuan (styled Xiyi, a famous Song Dynasty Daoist) remarked: Retaining the Yang essence determines longevity. However, ordinary people's Jing leaks from the Dantian (the lower abdominal sea of Qi)—this is both a place to guard and a point of leakage, the very crux of life and death. If one merely temporarily preserves the Jing without leakage, they will ultimately remain trapped in the cycle of birth and death like ordinary mortals.

True transcendence lies in continuing cultivation after "zhi huo": through the "seven days of chaos" (a state of deep meditation), one gathers the Golden Elixir. In the initial stage of "cai yao" (gathering the primordial Qi), it takes only a moment, as Bodhidharma said: "In two breaths, gather the mani pearl" (capturing the true Yang in two inhalations). When the primordial Qi is abundant and the Yang energy fully formed, one must further refine it through "peng lian" (circulating Qi with intention). The entire process hinges on precisely grasping the timing of "zhi huo"—this is the most profound secret in the transition from mortal to sage.

This passage explains the crucial Neidan (internal alchemy) cultivation processes of "herb gathering" (caiyao) and "fire cessation" (zhihuo) in Daoist practice.

The text clarifies that the heat felt in the Dantian (the lower abdominal energy center) isn't physical warmth, but rather an intangible fiery energy. Ancient practitioners described this state as "Dantian ablaze with fire" or "kidneys boiling like soup," akin to a blazing pearl. Only by cultivating this energetic manifestation can one advance to the realm of "spiritual transformation," forming a body beyond the physical. This energy is gathered from nothingness through dedicated practice, typically requiring seven days to manifest successfully.

During the first three days, tangible effects are often elusive. Between the fourth and seventh days, practitioners may experience the Dantian's fiery heat and a sensation of their kidneys churning like boiling water. Internally, this manifests as intense warmth; externally, it resembles turbulent boiling. Concurrently, wind-like sounds may arise behind the ears, while the Jade Pillow Pass (an acupoint at the back of the skull) resonates with bird-like calls—all signs of Qi circulation.

At advanced stages, a perfected golden light appears in one's vision, signaling abundant Yang energy. Within the Dantian, the "Great Medicine" (cultivated essence) coalesces like a luminous pearl. This process parallels the Buddhist concept of "retrieving relics after cremation," termed in Daoism as "gathering the Great Medicine to obtain the Mysterious Pearl."

This refined essence is called the "Mysterious Pearl from Water." The Yellow Emperor once acquired it through "formless means" (wangxiang). Others harvest it via the "Azure Dragon and Crimson Maiden" method (harmonizing Yin-Yang), succinctly termed "the Dragon Maiden presenting the pearl." Attaining this enables transcendence of mortality and calamity. Thus, the scripture emphasizes discerning the precise timing and method of "fire cessation"—failure to do so impedes accomplishment.

This passage discusses the importance of "guarding the Jing" (preserving essential energy without leakage) in Daoist cultivation. Multiple patriarchs emphasize that retaining the body's Yang Qi (original essence) forms the foundation of longevity.

The text points out that although many immortality seekers have read sacred texts, they fail to grasp the crucial principle of "stopping the fire" (preventing the dissipation of Jing and Qi). Those who can truly preserve their essence for even one day extend their life by one day, attaining the preliminary immortal fruit of "Human Immortality." When abundant Yang essence returns to the Dantian (the lower abdominal energy center), it establishes the basis for prolonged life. Lü Dongbin (Patriarch of Pure Yang) taught that cultivators can transcend worldly time—within their own vessel lies an entire cosmos.

Multiple patriarchs uphold this view: Wang Guozhai advocates constant vigilance against leakage, while Haike Lun stresses abstaining from sensual pleasures to preserve primordial Qi. The specific method involves using "Small Heavenly Circuit" (internal energy circulation) techniques to gently nurture gathered Yang essence in the lower Dantian. The Classic of Embryonic Breathing states that maintaining a state of emptiness cultivates Shen (spirit) and Qi—like a turtle holding water vapor in its mouth to safeguard the root of life. Zhongli Quan (Patriarch Zhongli) teaches that the fusion of water (Yin) and fire (Yang) refines the "Great Medicine" to eternally dwell in the Dantian, while Wang Chongyang asserts that treasuring true Qi in the energy center prevents death.

A final warning: without sustained guardianship of the lower Dantian, true Qi may still scatter due to desires, destroying the foundation of practice. All patriarchs agree: when true Qi does not disperse, life cannot perish; when life remains, the form does not vanish—this is the key to boundless longevity.

Xiao Zixu (Patriarch of the Southern Daoist School) said: Contemporary practitioners who fail to regulate their essence (Jing) and vital energy (Qi) labor in vain. One must understand the precise moment to cease the firing process (huohou, the energy regulation in Neidan practice), for only after proper cessation can the Great Medicine (dayao, the refined energy) be gathered, enabling transcendental liberation. At this stage, one attains the spiritual penetration of "exhaustion of outflows" (loujin tong), one of the six supernatural powers.

The penetration of exhausted outflows refers to the spiritual ability achieved when yang essence no longer dissipates—it forms the foundation of all six penetrations. When reaching this state, the male organ retracts like an infant's, fulfilling what the Avatamsaka Sutra describes as "possessing complete masculine form while achieving the Tathagata's concealed horse-genital mark"—even in old age, one regains youthful vitality. Those formerly prone to essence leakage cease such dissipation; those with depleted essence recover fullness. This resembles the thirty-second mark of the Buddha's physical perfection—"genitals withdrawn like a horse's"—indicating retractile capacity akin to a leech's contraction. This corresponds exactly to the realized state of authentic Daoist immortals, unattainable by those pseudo-Buddhist heterodox practitioners.

Those ignorant of proper firing cessation cannot proceed to the medicine-gathering (caiyao) stage, making true transcendence impossible. Adepts who truly comprehend cessation timing gather medicine with sufficient energy to open all passes, for they obtain pure energy from its source through precise firing regulation and impeccable cessation timing.

These five principles reveal cultivation's essence: With correct methods and authentic verification, immortality becomes inevitable. If energy fails to arrive during medicine gathering, as Qiu Chuji (the Daoist master) warned, "Insufficient firing prevents the golden essence (jinjing) from ascending." Some practitioners, unaware of cessation's proper signs, halt prematurely—resulting in inadequate firing, deficient true energy, and unformed Great Medicine. Thus no medicine can be gathered—a stern reminder to recognize cessation's true indicators.

Occasionally, gathered medicine proves too weak to open the passes. Though knowing energy's source, such practitioners lack refinement skill and miss optimal gathering moments. The harvested energy remains feeble, incapable of breaching barriers toward the Great Dao (Dao). Premature gathering yields impure, weak energy—as the I Ching's "Initial Nine: Do not employ" advises. Misusing such immature energy absolutely precludes significant attainment.

This scripture primarily discusses the various stages and effects of achieving immortality through Neidan (internal alchemy) cultivation.

The text states that persistently guarding the Dantian (the lower abdominal energy center) can lead one to become a "human immortal" with extended longevity. When the body's primordial Qi (vital energy) is abundant—as if preserving the Yang Jing (essential life force)—this constitutes a minor achievement in the pursuit of immortality. Those with sufficient Qi attain far greater results than ordinary people who carelessly deplete their essence and energy.

Several examples of longevity are cited: Peng Zu (Jian Keng) lived for 800 years, but this was merely a minor accomplishment achieved through "cai bu" (a cultivation technique of replenishment). Because he did not master the complete method of accessing innate primordial Qi (the inborn life energy), he could only prolong his life to 800 years without transcending the cycle of birth and death.

The scripture also mentions the Buddhist disciple Kasyapa, who lived for 700 years, and the monk Baotai, who lived for 1,072 years. Yet neither could reach the state of sharing the lifespan of heaven and earth or surpassing kalpic cycles (cosmic epochs). Only those who understand "zhi huo" (controlling the intensity of cultivation), obtain the elixir, unblock their meridians, ingest the perfected medicine, and enter deep meditative states (samadhi and spirit travel) can achieve such heights.

The Lingbao Duren Jing (Scripture of Salvation) states: The Dao’s lifespan is boundless, heaven’s lifespan is finite, and humanity’s lifespan is uncertain. Only the Zhenren (Perfected Ones) who merge with the Dao can attain immeasurable longevity. The immortal Lü Dongbin said: By refining the body into Qi through the cultivation of primordial Yang (innate vital Yang), one transcends the ordinary and enters sainthood—where 36,000 years count as a single year, 36,000 such years as a single kalpa, and 36,000 kalpas as a grand kalpa—ultimately reaching a lifespan equal to heaven and earth.

Finally, the teachings of Zhongli Quan and Zhang Ziyang are referenced: Once Neidan cultivation succeeds, one must cease further application of "fire phases" (adjusting cultivation intensity), or else the inner elixir will be damaged. Before achieving the perfected Golden Elixir, one must diligently cultivate; but once it is attained, one must know when to stop.

This scripture primarily discusses the concept of "Zhou Tian Huohou" (celestial cycle fire times) in Daoist cultivation, using celestial phenomena as metaphors for the circulation of Qi (vital energy) within the human body.

It first emphasizes the importance of knowing when to stop in cultivation practice. As Maitreya Buddha said, without moderation, even eighty thousand kalpas of practice would be in vain. Here, "zhi huo" (stopping the fire) refers to the need to conclude the practice appropriately when reaching a certain stage.

Regarding the explanation of Zhou Tian Huohou: Just as the sun completes a full celestial cycle (360 degrees) in one day and night, the genuine Qi within the human body follows a similar circulation pattern. During cultivation, Qi begins its movement from the lower Dantian (the Kun abdomen), ascends counterflow to the crown of the head (the Qian crown), then descends back to the lower Dantian, completing one full cycle. Ancient practitioners described this Qi movement as "the Yellow River flowing backward," "Cao Creek flowing backward," or "cave water flowing backward."

Xu Jingyang noted that this Qi circulation resembles the vertical and horizontal weaving of warp and weft threads in cloth-making. Completing one cycle per day, accumulating 360 cycles equals one year. In Golden Elixir (Jindan) cultivation, Qi circulates precisely in this daily pattern.

Yu Yuwu further explained that if one achieves harmonious upward-downward resonance with smooth Qi flow, a single breath can complete one Zhou Tian cycle. Han Xiaoyao used the metaphor of a "Dharma wheel" to describe this circulation, emphasizing the need for continuous and unbroken Qi movement.

The text concludes by stating that through 360 cycles (symbolizing one year), the human body can replenish the Qi depleted during that year. This represents crucial experiential wisdom summarized by ancient practitioners. The entire cultivation process mirrors a microcosm, regulating the self by emulating celestial movements.

This passage reveals the mysteries of the "Zhou Tian Gongfa" (Celestial Cycle Method) in Daoist cultivation. The Perfected Lord Xu Jingyang (a renowned Daoist of the Eastern Jin Dynasty) observed that the body's internal rhythms correspond to celestial patterns, highlighting two key numbers: 216 and 144.

From midnight (Zi hour) to mid-morning (Si hour), the six Yang periods are calculated using the Yang number "nine" – four nines making thirty-six degrees per period, totaling 216 degrees across six periods. Conversely, from noon (Wu hour) to late night (Hai hour), the six Yin periods employ the Yin number "six" – four sixes making twenty-four degrees per period, totaling 144 degrees. Combined, these perfectly complete the 360-degree celestial cycle.

Regarding the distinction between Grand Celestial Cycle (Da Zhou Tian) and Lesser Celestial Cycle (Xiao Zhou Tian): The Lesser Cycle refers to the daily 360-degree cultivation method used during the "refining essence into Qi (Lian Jing Hua Qi)" stage (the foundational hundred-day process of transforming Jing into vital energy). This involves six Yang periods for "advancing Yang fire" (strengthening Yang energy) and six Yin periods for "retreating Yin talisman" (harmonizing Yin energy) between midnight and late night.

The Grand Cycle differs significantly. As Patriarch Zhongli Quan (one of the Eight Immortals) stated, "A year of purification guards against peril," indicating an advanced stage beyond fixed degrees. The Perfected Being Zhang Ziyang (Northern Song Neidan master) particularly emphasized the inherent dangers of Grand Cycle practice, which cannot follow the systematic approach of the Lesser Cycle. While the Lesser Cycle requires precise timing and degree coordination, the Grand Cycle emphasizes Wuwei (non-action) and natural spontaneity.

The text also recounts how Master Wu (likely referring to the Perfected Being Wu Shouyang) received secret transmission from the Perfected Being Cao, with special emphasis on applying "Yang fire and Yin talisman": all Yang-strengthening techniques are called "advancing Yang fire," while all Yin-harmonizing methods are termed "retreating Yin talisman." When Wu sought further clarification, Perfected Being Cao solemnly declared this knowledge was heaven-mandated, requiring reverent acceptance without questioning.

The hours of Mao (5-7 AM) and You (5-7 PM) are crucial periods for "muyu" (special meditation sessions for calming the mind and regulating breath) in cultivation practice. The Avatamsaka Sutra similarly notes that all things follow natural rhythms, just as the wondrous wheel of Buddhist Dharma turns in accordance with time.

Huangfu Lüdao (a Daoist master) taught that cultivation should continue uninterrupted through all twelve two-hour periods of the day. Yu Yuwo (a Song dynasty Daoist) observed: Just as the Dao of Heaven operates without pause, so too must the path of alchemical refinement continue without cessation.

The Grand Celestial Cycle (advanced cultivation stage) is employed during the "transforming Shen (spirit)" phase - the ten-month cultivation period where innate Qi (vital energy) is refined into primordial spirit. Its profound secret lies in this paradox: while appearing as continuous operation, one actually enters a breathless state, naturally transitioning from conscious breathing to breathless absorption.

Xu Jingyang (renowned Jin dynasty Daoist) stated: The "fire times" (mindful regulation during practice) must adjust according to the transformations of the hexagram lines - without this fire regulation, vital energy cannot be generated. These teachings outline the essential principles of celestial cycle fire regulation.

Mastery of elementary fire regulation requires studying both the direct explanations in the Fire Times Scripture and the dialectical discussions in question-answer records. Yet the truly celestial mysteries that align with cosmic patterns can only be grasped through actual practice. When sitting on the meditation mat for personal verification, one naturally understands - oral transmission ultimately cannot exhaust these profundities.

Question: If one recognizes true Jing (essential vitality), why can't it be employed? Answer: This occurs when "regulating the medicinal agent" (adjusting primordial essence) hasn't been properly prepared. One must first regulate the timing of its emergence during that liminal state before manifestation, so it can be naturally gathered when emerging. This "regulation" constitutes preparatory work prior to collection, distinct from the adjustments made during fire application.

Follow-up: Since ancient times, only breath regulation was considered fire timing - why emphasize medicinal regulation now? Answer: This constitutes the celestial secret strictly guarded by immortals through the ages. As Daoist precepts forbid casual transmission, later practitioners must master this method to achieve the Dao. Without this essential formula, we cultivators cannot obtain the deathless primordial Qi, making immortal attainment impossible.

This scripture reveals the core secrets of cultivating the Golden Elixir (Jindan) path. The essential teachings transmitted by Masters Cao Huanyang and Li Xu'an emphasize seizing opportunities for practice amidst worldly busyness, obtaining the primordial Qi (Xiantian Qi, known as "external medicine") from the void. This is not a solitary practice for personal benefit alone, but a crucial method that must be passed down to future generations.

The text stresses that the Dao of the Golden Elixir fundamentally differs from common worldly understanding. What ordinary people consider as "medicine arising at fixed times" (referring to cultivation timing) is actually heretical doctrine—the true celestial immortality path has its own unique methods and timings for refining the medicinal essence. Those obsessed with debauchery cannot believe in the orthodox path of spiritual cultivation, mistaking licentious acts for practice, and thus remain ignorant of authentic medicine-refining techniques.

The author warns skeptics to observe practitioners of heterodox methods: despite years of arduous cultivation, they achieve nothing, and even past masters of these ways ultimately meet their demise. This proves only the celestial immortality path holds true methods. The genuine medicinal substances (Jing, Qi, and Shen required for cultivation) demand special refinement—ordinary people neither know nor can perform this process. Without proper medicine refinement, the vital energies remain "either too aged or too tender" (indicating impure energy), failing to provide nourishing effects.

Finally, quoting Bai Yuchan's wisdom: if the medicinal substances (cultivation materials) lack purity, the resulting Golden Elixir will prove ineffective. This reveals the exacting quality requirements for materials in Golden Elixir cultivation.

The key to Neidan (internal alchemy) practice lies in mastering the proper method of "regulating the medicinal ingredients." This refers to adjusting the body's Jing (essence) and Qi (vital energy) through specific techniques until they reach a state of sufficient abundance for harvesting and refinement. Without understanding this regulation method, one cannot obtain truly sufficient primordial Qi (Yuanqi). This leads not only to the instability of essence-energy—manifesting as irregular growth and unpredictable fluctuations—but also renders the harvesting process ineffective, thwarting the pursuit of immortality. Persisting in such errors despite knowing better is tantamount to courting death.

Timing is crucial in medicinal regulation. Harvesting at improper moments either yields insufficient essence-energy or misses the optimal window entirely. Such misguided attempts not only fail to replenish vital resources but degenerate into blind practice. True masters of regulation can identify the natural moment of essence-energy emergence for proper harvesting—what is called "True Yang"—which alone qualifies as the genuine "Great Medicine." Each cultivation session demands such precision; the slightest deviation results in inadequate essence-energy, preventing the formation of Great Medicine and making celestial immortality impossible.

Perception forms the core of medicinal regulation. Authentic awareness yields genuine Qi, while its absence precludes success. Beginners often err by hastily harvesting newly emerged essence-energy when it remains too tender and weak for elixir formation. One must wait until the essence-energy reaches full vigor before harvesting for effective nourishment. When essence-energy accumulates to a certain threshold, it signals the formation of Great Medicine—this abundant vital force can break through the Three Passes (critical junctures in cultivation) to assist in achieving immortal states. Insufficient essence-energy naturally prevents both the emergence of Great Medicine and the breakthrough of these passes.

Regarding timing, worldly practitioners often debate the "ripeness" of essence-energy's emergence (referring to its developmental maturity). The celestial path discerns this through perceiving the energy's natural rhythms, while heterodox methods rely on external bodily signs—this distinction marks the divide between orthodox and unorthodox practice. Authentic regulation requires apprehending the "pure and primordial" pre-physical state of essence-energy, rather than clinging to the "turbid and subsequent" manifested forms. The axiom "true awareness comes from authentic perception" emphasizes this very principle of regulation through genuine insight.

This scripture primarily discusses how to properly approach Jing (essence), Qi (vital energy), and Shen (spirit) in the cultivation of immortality, emphasizing the importance of pure practice while criticizing heterodox methods that seek to obtain vital essence through sexual intercourse.

The text first establishes that complete freedom from delusional thoughts forms the foundation of pure cultivation. If one practices with lustful intentions, they will only obtain defiled substances—a grave taboo in spiritual cultivation. Only those who truly understand this principle can acquire authentic Jing as the foundation for their practice.

Drawing from Buddhist perspectives, the text explains that sexual desire represents worldly obstacles, and lustful thoughts constitute delusional cognition. Following these mundane attachments leads one to fall into demonic paths and the cycle of rebirth, while transcending them aligns with the true Dao. Here, the text points out the initial convergence between Buddhist and Daoist paths at the entry level.

Wu Taiyi raises a question: It's said that Daoist cultivation involves three key elements—the medicinal substance (yaowu), the firing process (huohou), and the crucible (dingqi). However, some mistakenly regard women as their crucible, seeking to obtain essence through intercourse as their medicinal substance—a practice entirely condemned as heretical and demonic.

The text cites multiple masters to refute such heterodox views:

• Chen Niwan states authentic cultivation lies in harmonizing Yin-Yang within one's own body (the "inner husband and wife")
• Bai Yuchan criticizes ignorant practitioners who indulge their lusts, mistakenly closing the coccygeal pass (a cultivation term) while attempting to harvest Yin energy from others, mistaking ordinary semen for the Golden Elixir (Jindan)
• Ge Hong (Baopuzi) explicitly declares that sexual techniques for achieving immortality are pure demonic falsehoods—deceptive tools used by charlatans to mislead people. Such practices not only fail to bring immortality but hasten death
• The "Gushen Pian" states that although heterodox methods appear numerous, none escape impermanence
• The "Jade Emperor's Essential Conduct Scripture" observes that while countless mixed methods exist in the world, only by purging these adulterated energies can true Daoist practice be implemented

Finally, the text explains why some essence, though seemingly authentic, cannot serve as true Jing: This occurs because practitioners of pure immortality cultivation encounter both "known" and "unknown" conditions. Some may recognize the timing of true Jing's emergence, but due to insufficient mental clarity, their Shen (spirit) cannot properly guide the process, preventing retention of authentic essence. This illustrates the crucial importance of mental cultivation in spiritual practice.

The true Jing (essence), referring to the pure life energy within the human body, naturally arises when one reaches a state of profound stillness and tranquility, even without lustful thoughts or actions. This Jing that stirs during deep meditation is the purest form, innate to every person from birth. However, practitioners who haven't received authentic Daoist transmission often fail to recognize the precise moment when true Jing emerges—because their Shen (spirit) lacks awareness.

When the Shen loses its acute perception, one cannot properly execute the cultivation techniques of "gathering the medicine" (collecting vital essence) and "harmonizing Yin-Yang," making it difficult to retain this genuine Jing and return to stillness. Thus, they miss the crucial opportunity for sustained nourishment and growth of their vital energy. There are two primary reasons why such practitioners fail to utilize true Jing effectively:

First, though they may have heard theories about the emergence of true Jing, they never personally verify its actual manifestation within themselves. This resembles the Confucian saying, "Mere speculation without practice leads to confusion." Unable to synchronize their Shen with the optimal moment for gathering, they either collect the Jing too early—when it's still immature and weak—or too late, when it has already dissipated. Consequently, they cannot condense the Golden Elixir (the highest achievement in Daoist Neidan/internal alchemy) or complete the "Great Medicine" (the refined substance essential for cultivation).

Second, the emergence of true Jing naturally manifests discernible signs. Yet worldly deluded practitioners, following heterodox methods, mistake false arts for the immortal path, content with superficial knowledge while neglecting genuine techniques. Others who follow the path of purity, though devoted to scriptures, lack authentic transmission. They understand the principle that "purity reveals truth" but fail to recognize the precise "fire timing" (the critical moment when Jing is neither too young nor too old) for gathering and refining. As a result, they either miss the true Jing entirely or mistakenly collect false energy, ultimately failing to complete the process of "replenishing essence to transform Qi" (refining Jing into higher energy).

This isn't entirely the fault of ordinary people—the Daoist path contains celestial secrets rarely revealed in the mortal realm. Only true immortals comprehend these heavenly mysteries; common folk may occasionally hear of them but find them impractical to apply. Should anyone truly master this method, it must be due to accumulated wisdom from past-life cultivation and lifelong diligence from youth to adulthood, culminating in a celestial immortal personally transmitting the esoteric teachings.

This scripture elucidates the essential points for attaining immortality through cultivation, emphasizing that enlightenment of the Dao can only be achieved through sincere and earnest practice. The author admonishes future practitioners to contemplate these teachings carefully, as those who cultivate blindly often achieve nothing.

Through a dialogue format, the text reveals the mysteries of cultivation: When the authentic Jing-Qi (essence and vital energy, fundamental life forces in Daoist practice) arises within the body, the Shen (spirit) naturally perceives its profound mechanism. However, practitioners must pay special attention to discerning when to employ and when to refrain from using this vital essence. The secret of recognizing true Jing is not easily known by ordinary people—it can only be comprehended through diligent practice.

The scripture particularly emphasizes that this path of cultivation differs from worldly methods. It is the way of celestial immortals and sacred beings, attainable only through transcending mundane concerns and committing to ascetic practice. Even the Three Pure Ones (Yuanshi Tianzun, Lingbao Tianzun, and Daode Tianzun) of the Great Luo Heaven (the highest Daoist celestial realm), the Four Min Heavens (four cultivation states), and the thirty-six Celestial Venerables and Imperial Sages within and beyond the Three Realms collectively safeguard these mysteries, never revealing them lightly.

The text subsequently details the Daoist celestial hierarchy: from the lowest Six Heavens of the Realm of Desire (including Huangzeng Tian and Yuwan Tian), through the intermediate Eighteen Heavens of the Realm of Form (including Yueheng Tian and Mengyi Tian), up to the highest Four Heavens of the Formless Realm (including Xiaodu Tian and Yuandong Tian)—totaling twenty-eight celestial tiers. Beyond these lies the Great Luo Heaven of the Three Pure Ones, situated above the Four Min Heavens and outside the Three Realms, representing the ultimate state of cultivation.

This scripture describes the celestial hierarchy in Daoism. It first explains the "Three Realms" (Desire Realm, Form Realm, and Formless Realm) comprising twenty-eight heavens, with the final four being the Formless Realm's Miaocheng Heaven, Jinshang Heaven, and others. Above these Three Realms exist four "Seed-People Heavens" (Changrong Heaven, Tengsheng Heaven, Fandu Heaven, and Jiayi Heaven), beyond which lie the supreme Three Pure Heavens (Sanqing): the lowest is Taiqing Great Crimson Heaven (Dongshen), the middle is Shangqing Yuyu Heaven (Dongxuan), and the highest is Yuqing Qingwei Heaven (Dongzhen). The "Three Caverns" (Dongzhen/Dongxuan/Dongshen) signify realms of infinite transcendence. Above the Three Pure Heavens is the all-encompassing Great Net Heaven (Daluo Heaven), collectively forming a thirty-six-layered celestial system.

The scripture particularly emphasizes that this celestial knowledge represents profoundly precious mysteries, entirely distinct from mundane understanding. According to celestial law, reckless disclosure of these secrets incurs the "Trial of Wind-Blade" (celestial punishment) and the "Three Torments" (suffering in hell). Even those with immortal destiny who receive such teachings will invite calamity if they divulge them carelessly or allow the unworthy to hear them. The text cites examples like Ye, Mo, and Xu, who died suddenly after heedlessly listening, and a case where a divulger suffered illness for three years—demonstrating how these celestial secrets demand utmost reverence.

Finally, it explains that the rarity of Golden Elixir (Jindan) attainment and transcendent longevity in the mortal world stems precisely from the lack of such pure and authentic transmission. The revelation of these celestial mysteries requires practitioners to possess profound karmic merit and unwavering devotion to the Dao (Dao-xin).

This dialogue explores how the cultivation of the Golden Elixir (Jindan, the core concept of Daoist Neidan practice referring to the crystallized life energy formed through the transformation of Jing, Qi, and Shen) fundamentally depends on obtaining the "purest and truest" primordial Qi (the innate vital energy). Master Chen Niwan emphasizes that the Golden Elixir represents the only true path to immortality, and its essential secret lies in acquiring this perfectly pure and abundant primordial Qi.

Wu Zi explains that without obtaining this purest primordial Qi, it would be like trying to cook rice with an empty pot—no matter how long one boils water, no rice will materialize. This explains why many practitioners fail to achieve results despite years of cultivation. Conversely, by accessing this pristine Qi, each cultivation session replenishes one's vital essence, enabling completion of the foundational stage (Zhuji) within a hundred days—a relatively accessible method of practice.

The purest primordial Yang essence (the fundamental life energy) emerges from a state of profound stillness and emptiness. This energy, being utterly pure and authentic, marks the usable moment for cultivation. However, practitioners must note that when initially sensing insufficient energy, they shouldn't rush to employ it. Only when it becomes truly abundant can it be used to "replenish essence and transform Qi" (the process of refining acquired essence into innate Qi through practice), thereby restoring the original abundant state of one's innate foundation.

In truth, every person is born with abundant primordial Qi, which only becomes depleted through desires. Therefore, the practice involves rediscovering this inherent plenitude for replenishment. This replenishment requires no external seeking—simply through tranquil awareness can one perceive it. When practitioners learn to clearly discern and access this pure, abundant energy, they can refine the supreme medicine of the Golden Elixir (the highest achievement in cultivation) and attain the immortal state of longevity. The key lies in the practitioner's ability to accurately recognize what constitutes genuinely pure and sufficient energetic states.

This passage reveals the core principles of attaining immortality through cultivation and the solemn attitude required when transmitting celestial secrets. Practitioners can refine their Jing (essence) and Qi (vital energy) to replenish life force without relying on complex external methods—by laying the foundation in just one hundred days, they can forge the Golden Elixir (Jindan). These are genuine secrets of immortal Dao, but if imparted to those who lack proper understanding or are unworthy of the celestial opportunity, they will fail to manifest their true power.

The author acknowledges writing this at the risk of divine retribution, intending only for destined individuals to comprehend that following the correct path leads swiftly to the Great Dao (Dadao), ascending to the highest celestial realm of the Three Pure Ones (Sanqing). Yet he sternly warns future recipients to guard these teachings carefully. While he outlines the essential framework, the actual practice requires personal realization.

For those with shallow roots or wavering faith, even direct inquiries will not elicit the core mysteries. Celestial secrets (Tianji) may only be transmitted to diligent practitioners who uphold precepts and accumulate merit—and only after petitioning the heavenly courts for approval. Quoting multiple patriarchs, the text emphasizes: Ma Danyang declared celestial secrets must not be lightly shared, but matched to the recipient’s wisdom; Xue Daoguang cautioned against revealing the Great Dao to the unworthy; Chan masters would rather face hell than indiscriminately spread Buddhist teachings; and Lü Dongbin (one of the Eight Immortals) stressed that the Three Pure Ones’ esoteric methods demand silent, imageless absorption—if seekers lack focused resolve, all questions and answers are futile.

A final warning: those who rashly disclose or pry into celestial secrets will incur heaven’s punishment, both speaker and listener alike. The core message underscores the preciousness of genuine immortal teachings and the rigorous conditions for their transmission.

Those who disclose celestial secrets violate heavenly laws, and listeners lacking sufficient virtue will likewise incur punishment. To cultivate the Dao, one must first uphold purification practices (referring to practices that cleanse body and mind, abstain from meat, and other ascetic disciplines), diligently contemplate its principles, and petition the heavens for permission. Only with celestial approval and guidance from an immortal can one succeed in cultivation.

If someone privately transmits Daoist methods without first petitioning the heavens, they commit the grave offenses of leaking and stealing celestial secrets—retribution will swiftly follow. The Scripture of the Three Primes' Precepts and Admonitions records that crimes such as recklessly teaching sacred scriptures to unworthy individuals, transmitting methods without proper ritual petitions to the celestial realms, or distorting scripture to contradict the sages' intent are punished with thirty-six forms of excruciating wind-blade torture by the celestial officials. Disclosing divine secrets, forging scriptures to slander the Dao, and similar offenses are judged by the Three Primes' Spiritual Courts (Daoist deities overseeing karmic reckoning).

History offers many cautionary tales: Hua Qiao’s reckless discussion of celestial secrets led to his father and son being punished by the Water Official; Zhang Ziyang, a realized master, mistakenly transmitted teachings to unworthy recipients three times and suffered heavenly retribution; Li Xu’an rashly imparted methods to Ye and Mo, resulting in three years of bloody flux for himself and both disciples dying of dysentery. These cases demonstrate the stern and inviolable nature of celestial law.

Yet, considering that sincere later practitioners may struggle to discern truth from falsehood, and compassionate teachers fear no one will believe them, these warnings must remain as guiding principles for future cultivators.

Regarding Xue Daoguang’s verse, "The sage transmits the medicine but not the fire," and the saying, "The immortals conceal not the difficult but the easy": the "untransmitted medicine" spoken of today differs entirely from worldly teachings. That I alone received the true transmission is due to blessings accumulated over past kalpas of cultivation. Otherwise, among so many seekers in the world, why would I alone hear it? This shows that true transmission requires karmic affinity from past lives.

The discussion here revolves around the mystery of why the fire times (a crucial stage in Neidan/internal alchemy practice) cannot be casually transmitted. The response clarifies that mastering fire times fundamentally depends on personal realization. This concept of self-realization implies both the reluctance to transmit it indiscriminately and the understanding that mere verbal explanation or passive listening is insufficient. Only through single-minded dedication and diligent effort can one truly grasp the subtleties of fire times, ensuring the practice aligns perfectly with its exquisite timing and yields genuine experiential results. Failure to do so risks straying into heterodox methods, such as those overly focused on breathing techniques alone.

The text recounts how Ma Ziran (a Song dynasty Neidan practitioner), after meeting Zhang Ziyang (patriarch of the Southern Lineage of internal alchemy), lamented: "Those Daoists spend their days performing countless prostrations, engaging only in breathing exercises, swallowing saliva, and shaking their bones and sinews. Practicing until midnight, drenched in sweat—such cultivation involves both life and death, making them no different from ordinary people."

At the time, scholars like Zhou Nanyu and military examination candidate Hu Maoyuan inquired at the Daoyin Studio: "Practicing fire times resembles breathing exercises, and descending the 'heavy tower' (the process of primordial Qi descending) seems like swallowing saliva. How does one distinguish the immortal path from heterodox methods?" The reply was: "The immortal path uses tangible breathing as a means to circulate the intangible primordial Qi. Ultimately, even the tangible breathing returns to the intangible—this is the subtle and natural state. Heterodox methods, however, fixate solely on the physical act of breathing, inevitably leading to various ailments. For instance, if the ascent is too slow or forceful, it transforms into perverse fire, causing dizziness, red swollen eyes, phlegm-fire coughs, or abscesses. If the descent is too slow or heavy, coarse and turbid Qi sinks into the kidneys, resulting in testicular pain, hernias, or abdominal distension. These upper and lower disorders can swiftly prove fatal, bearing no resemblance to the immortal path."

In the immortal path, descending the "heavy tower" refers to the process of primordial Qi returning to its root—it is not about swallowing saliva. Saliva is a tangible secretion from the mouth, incomparable to intangible primordial Qi. When Qi descends to the Qi cavity (Dantian), it replenishes Qi and nourishes Shen (spirit), whereas swallowed saliva merely enters the spleen and stomach, eventually becoming urine, with no experiential effects. This is the fundamental distinction between orthodox and heterodox methods.

Finally, the text emphasizes the importance of comprehending and aligning with celestial timing. This timing encompasses: the four daily periods of Zi, Wu, Mao, and You; the four seasons of spring, summer, autumn, and winter; and the specific hours crucial to cultivation.

This passage discusses the coordinated application of "fire timing" (huohou) and "medicinal substances" (yaowu) in Daoist cultivation. "Harmonious blending" (chonghe) refers to the balanced state of Yin and Yang energies, where cultivation must align with seasonal changes (the four seasons corresponding to Wood, Fire, Metal, and Water phases) to regulate Qi. The Cantongqi (参同契) states that only by following these seasonal rhythms can one unite with primordial Qi (Yuanqi) — this being the fundamental principle of cultivation.

The author emphasizes that genuine experiential realization in cultivation cannot be fully conveyed through language, as words originate from the mouth and tongue, while true understanding arises from heartfelt realization. A key explanation concerns the application of "fire timing": the "Zi hour" in cultivation does not refer to midnight in ordinary timekeeping, but rather to the moment when vital energy stirs within the body (known as "living Zi hour"). Fire timing must be activated precisely when the "medicinal substances" (the Jing-essence and Qi within the body) emerge — forcibly applying fire without the presence of these substances proves harmful. The emergence of medicinal substances and the activation of fire timing occur simultaneously, both termed as manifestations of the "living Zi hour."

The crux of cultivation lies in the coordinated interaction between "Shen" (consciousness) and "Qi" (vital energy): Shen directs the movement of Qi, and the two must remain mutually aware and harmoniously aligned. If Shen fails to perceive Qi, or if Qi doesn't follow Shen's guidance, this leads to disharmony between the Metal (lungs) and Wood (liver) energies. When Qi can move according to Shen's direction, it establishes the foundation for longevity; when Shen can operate in accordance with Qi's flow, it manifests spiritual transformations. Such subtle coordination requires dedicated experiential understanding from practitioners — a depth of realization that transcends verbal description.

This scripture elucidates the crucial principles of coordinating Shen (spirit) and Qi (vital energy) in Neidan (internal alchemy) practice. To transcend the cycle of birth and death, practitioners must achieve perfect harmony between their Yuanshen (primordial spiritual consciousness) and Yuanqi (primordial life energy). Without this synchronization, one remains bound to the samsaric existence of ordinary beings.

True coordination manifests when Shen and Qi become mutually perceptive and merge into unity. When consciousness focuses on the Qixue (Dantian, energy center), Qi naturally follows. Conversely, if consciousness moves while Qi remains stagnant, or Qi flows while consciousness becomes inert, these imbalances lead to the separation of Shen and Qi, preventing completion of foundational practices like "building the foundation," "nurturing the embryo," and "transforming the spirit."

The practice requires mastery of "civil and martial fires" - the intensity of mental focus. Wenhuo (civil fire, gentle attention) is employed during ascending phases, while Wuhuo (martial fire, intense concentration) is used during descending phases. Master Yu Yuwu taught that alchemical practice should begin with civil fire before transitioning to martial fire. However, the application must be precisely balanced - excessive gentleness lacks potency, while excessive force becomes strained. The transition between firmness and softness should mirror the natural progression of seasons.

During the ascent of Shen-Qi, congenital Yuanqi (innate energy) must coordinate with acquired respiratory Qi; during descent, practitioners must align with seasonal qi transformations, allowing spirit-energy to return to its origin. This cultivation follows natural rhythms as surely as the cycle of spring, summer, autumn and winter.

The text particularly emphasizes that while ancient sages often used metaphors to describe Taixi (embryonic breathing, the quiescent breath state in deep meditation), this teaching directly reveals the mysteries of Shen-Qi coordination. These essential principles contain previously undisclosed精髓 (essence) unlike other classics that rely on layered analogies. Given the supreme importance of the Great Celestial Cycle (advanced practice stage), celestial immortals never transmit these teachings lightly, earthly masters dare not explain them carelessly, and later practitioners must never treat these principles with disrespect.

This scripture elucidates the mysteries of "embryonic breathing" (taixi) in Daoist cultivation. Embryonic breathing—an advanced respiratory state resembling a fetus's breathing in the womb—comprises two levels: the lesser celestial cycle (xiao zhoutian) and the greater celestial cycle (da zhoutian).

In the initial stages of practicing embryonic breathing, one transitions from a state of "non-breathing" (wuxi) to "breathing" (youxi), yet the actual sensation resembles the absence of breath. This is a phase where the states of "being" (you) and "non-being" (wu) alternate in application. The so-called "formation of the embryo" refers to the initial consolidation of the original spirit (yuanshen), which guides the primal qi (yuanqi) and the breath's qi to return to the dantian (qi cavity), establishing a stable condition. However, it is crucial to note that the original qi and breath qi in the dantian naturally tend to disperse outward; the practice aims to reverse this tendency and gather them back.

In authentic immortal Dao cultivation, even when entering the "breathing" state, one does not cling to the breath—hence the description "seemingly present yet detached." This differs from heterodox methods that forcibly control respiration. The highest state of embryonic breathing is as described by Master Dao Yi: "There is no stillness that does not move," where "being" and "non-being" mutually transform.

At the final stage of cultivation, embryonic breathing transitions from "being" to complete "non-being"—a total cessation of breath, attaining the realm of quiescent nirvana. Here, "being" refers to a stable state of internal breathing, distinct from ordinary respiration. As mentioned earlier, it appears as "seemingly non-existent" before ultimately achieving true "non-being." At this point, breathing ceases entirely, and one enters the state of extinction (jimie).

This scripture discusses the state of "extinction samadhi" (a profound meditative absorption). In true great stillness, although breathing nearly ceases, if even the faintest breath remains unbroken, one has not yet fully attained "nirvana without residue" (complete liberation). Only by fully entering the quiescent state of extinction and maintaining this great stillness can the yang spirit (the cultivated primordial spirit) truly manifest. This is the authentic emergence from meditation, equivalent to what the Avatamsaka Sutra calls the "appearance of the Tathagata."

Through uninterrupted cultivation, practitioners form the "embryo" (referring to the sacred embryo in Neidan practice), embodying the principle of "all dharmas returning to One." As long as this "One" exists, it remains perceptible to the eyes, tangible to the mind, and expressible in words—just as the Diamond Sutra states: "Thus should one abide"—a bodhisattva should dwell according to the methods taught by the Buddha.

The phrase "non-cessation as the embryo" refers to attaining the breathless state through regulating embryonic respiration (a profound internal breathing technique). Master Xiao Zixu, a patriarch of Daoist Neidan, once said: "By preserving the Qi of true Oneness, breathing naturally ceases. When the mind returns to singularity, respiration settles." True embryonic respiration is this "One" to which all dharmas return—the ultimate refuge for practitioners.

The Shurangama Sutra teaches that without understanding the functions of mind and eye, one cannot subdue worldly afflictions. The Diamond Sutra's instruction to "abide" means anchoring the mind in respiration, the foundation for cultivating the Dao embryo (Neidan). Meditators must grasp this principle: the mind relies on true respiration (innate breathing) to enter samadhi (deep absorption), undisturbed by the six dusts (sights, sounds, smells, tastes, touches, and mental objects). Only when the six roots (eyes, ears, nose, tongue, body, and mind) abide in right concentration can awakening occur.

The Buddha attained enlightenment through this method of abiding and taught it to the world. The Avatamsaka Sutra describes bodhisattvas dwelling in the Buddha's abode, while the Diamond Sutra similarly instructs bodhisattvas to abide according to the Buddha's teachings—only thus can they reach the Buddha's state. Ultimately, through the breathless great samadhi, the sacred embryo is perfected, and even this "One" returns to emptiness, achieving true transcendent stillness.

This passage discusses the realization of "the extinction samādhi" (a profound meditative state) in Daoist cultivation. Chen Niwan (a renowned Neidan master of the Song Dynasty) states that when practitioners reach a state of mental emptiness and complete cessation of breath movement, it is called "Great Stability." Master Zhao (a Neidan patriarch of the Song Dynasty) similarly emphasizes that true cultivation requires no deliberate calculation of "fire times" (huohou, the stages of alchemical process); the key lies in comprehending the state of "neither coming nor going."

The term "extinction" first refers to the quiescence of both primordial qi (original vital energy) and postnatal breathing. When both types of qi completely stabilize, one attains the Great Stability. Secondly, it signifies the cessation of the cyclical arising and ceasing of mental activity. Ordinary people experience endless thought fluctuations, but when adepts achieve Great Stability, these cycles vanish entirely, and one's true nature realizes quiescence.

Chen Niwan shares his personal experience: After a year of practice, the six pulses (three pulse positions on each wrist) cease their movement as qi returns to its root. This verifies the actual attainment of the "Ten-Month Barrier" (a critical phase in Neidan practice). Pulse cessation occurs only after breath has stopped—complete stillness manifests only upon reaching the extinction samādhi. The Avataṃsaka Sūtra describes how breath ceases in the second dhyāna, pulse stops in the third dhyāna, and the fourth dhyāna enters the extinction samādhi where both breath and pulse become utterly still.

Wang Chongyang (founder of the Quanzhen tradition) characterizes this state as "neither increasing nor decreasing, neither arising nor ceasing, without rising." "Without rising" denotes the complete stillness of qi, akin to the Buddha's samādhi of unmoving absorption. The Diamond Sūtra advises bodhisattvas to "practice generosity without abiding"—meaning the mind must first dwell in Dharma, yet clinging to Dharma becomes another fetter, just as attachment to the six dusts (sights, sounds, smells, tastes, touches, and mental objects) binds ordinary beings. Only by transcending attachment to Dharma can one realize the liberated state of eternal bliss, true self, and purity.

As Buddhist scriptures state: "Dwell in supreme awakening with purified thought." "Purified thought" refers to non-arising, non-ceasing awareness—untouched by worldly delusions yet free from clinging to Dharma appearances. "Supreme awakening" is the ultimate perfect Buddhahood; abiding here attains the highest fruition, achieving the ultimate realization of all-pervading spiritual light. This embodies the true meaning of "dwelling serenely in all samādhis, with wisdom entering the deathless path."

This passage elucidates the shared principles between Buddhist meditation practice and Daoist Neidan (internal alchemy) cultivation. It begins by explaining the state of "abiding in stillness," referring to practitioners attaining the Great Stability (Dading), permanently dwelling in Nirvana Without Remainder (the liberated state beyond the cycle of birth and death), thereby naturally obtaining eternal peace and joy.

Authentic meditative wisdom arises from genuine awakening within the state of concentration. By entering the state of Right Enlightenment (complete awakening) through proper meditation practice, one can realize the Dao of immortality. This truth was personally verified by the Buddha, yet later generations of monks failed to comprehend it—they neither believed the Buddha had attained the deathless state nor persisted in meditative practice, instead resigning themselves to mortality and falling into the "view of annihilation" (the erroneous belief that everything becomes void after death).

The text mentions "wondrous vision" and "wondrous knowing": wondrous vision means neither clinging to form nor emptiness, transcending all appearances while seemingly perceiving; wondrous knowing means cognition beyond conceptual discrimination, transcending knowledge while seemingly knowing. Realizing this state leads to a realm beyond both ordinary knowledge and Buddha-forms—this constitutes true return to "non-being" (Wu).

However, this "non-being" should not be mistaken for a dark, obscure void. It refers instead to the genuine emptiness free from artificial constructs and clinging discriminations. Here, "knowing and seeing" denote the Right Knowledge and Right View of enlightenment, distinct from worldly opinions or heretical nihilistic misconceptions. Practitioners must enter meditation guided by the Right Knowledge of Dharma to realize authentic "non-being." Without such guidance, the Shen (spirit) cannot concentrate, Qi (vital energy) cannot return to the Dantian (energy center), and one becomes unable to fully nurture the "embryonic spirit" (a Neidan term referring to the cultivated primordial spirit), ultimately falling into a dark, ignorant void state that obstructs enlightenment.

As Chen Niwan (a renowned Song dynasty Neidan master) wisely stated: If the mind becomes completely blank and consciousness dull, how could one possibly gather Jing (essence) and Qi to accomplish the immortal embryo? Therefore, "absence of knowledge and vision" is also incorrect, as it prevents recognition of the true nature of original being. Authentic awakening constitutes a complete process from initial realization to full enlightenment, which must be cultivated through the Right Knowledge of immortals and Buddhas.

This scripture discusses the realm of "non-being" (wu) in spiritual practice and the importance of correct awareness and understanding.

The so-called "non-being" refers to a state where the mind is free from arising and ceasing thoughts, and breathing reaches its ultimate state of neither entering nor exiting. Without arising and ceasing thoughts, one avoids false perceptions and maintains proper awareness; without the movement of breath, one avoids deluded activity and enters true meditative stillness. This is the genuine realm of "non-being."

Only those who have attained the enlightened awareness of a Buddha can comprehend this state, which transcends verbal expression. Some misguided individuals in the world claim to understand the Dao of immortals and Buddhas, yet they fail to grasp the true meaning of "tranquility that is ever illuminating." Genuine correct awareness is inherent in our original nature—everyone possesses it. Only through correct awareness can one perceive this original nature, which is none other than the immortal or Buddha. Those who deny correct awareness fall into the error of "stubborn emptiness" (a mistaken view of emptiness)—how could they ever recover their original nature and become immortals or Buddhas?

The Neimi Zhenzang Jing (Scripture of the Inner Secret True Treasury) states: The Great Vehicle (Mahayana) Dao transcends all forms and actions, awakening to the fundamental emptiness and stillness of all phenomena. Awakening means realizing there is nothing to awaken to; stillness means reaching a state where there is nothing to still. This state of "awakening without awakening" and "stillness without stillness" is the supreme Great Dao.

These are profound states that require deep realization and secret cultivation to attain. The Miaofa Lianhua Zhenjing (True Scripture of the Lotus of Wonderful Dharma) says: Those who neither cling to existence nor non-existence and forever transcend arising and ceasing can be called "true persons" (zhenren).

The author notes that these words are merely superficial descriptions, capturing less than one ten-thousandth of the actual state. Language can only approximate the meaning—true understanding must wondrously merge with the Dao. Readers are cautioned not to cling to these teachings, mistaking hearing for attainment or knowledge for realization. Hearing teachings yields only shallow understanding; genuine insight comes from inner awakening.

Finally, it is emphasized that the most crucial thing is to resolve with determination, practice diligently, and genuinely embody and realize these truths.

This passage explains the method of coordinating breathing with the rising and descending of fire times (huohou) in Daoist Neidan (internal alchemy) practice. The breathing process consists of two phases—inhalation and exhalation—each corresponding to distinct cultivation principles.

During inhalation, the Qi (vital energy) should follow the breath's upward movement to the crown of the head (the Qian position, symbolizing Heaven). The emphasis here is on ascension without descent—not that descent is entirely absent, but that rising dominates to such an extent that it appears as pure ascent without decline. During exhalation, the Qi follows the breath's downward flow to the abdomen (the Kun position, symbolizing Earth), where the focus shifts to descent without ascent, creating the impression of pure downward movement.

Zhongli Quan (one of the Eight Immortals) instructed Lü Dongbin with this principle: "When it's time to rise, one must not descend—this is the subtle function of inhalation; when it's time to descend, one must not rise—this is the subtle function of exhalation." For instance, during the "living midnight" (huo zishi, the moment of initial Yang energy movement within the body), when the primordial Jing (essence) arises and naturally flows downward, the practitioner must use ascending methods to "gather" (cai) it back to the Dantian (energy center)—this constitutes the "harvesting" technique.

From the Zi hour (11 PM-1 AM) to the Si hour (9-11 AM)—the six Yang hours (Zi, Chou, Yin, Mao, Chen, Si)—the practice should emphasize ascension, using upward movement to deliver the "medicine Qi" (cultivated energy) to the crown, thereby completing the work of "returning the essence to replenish the brain" (huan jing bu nao). From the Wu hour (11 AM-1 PM) onward through the Hai hour (9-11 PM)—the six Yin hours (Wu, Wei, Shen, You, Xu, Hai)—the focus shifts to descent for the process of "refinement" (penglian, gentle tempering). This essential method is subtly indicated in the preface to Zhang Boduan (Ziyang Zhenren)'s Four Hundred Words on the Golden Elixir (Jindan sibai zi).

In the practice of Neidan (internal alchemy), one must utilize the "cauldron vessel" (referring to the Qi cavities within the Dantian). When encountering specific timing conditions where the Qi mechanism lacks the prerequisite for ascension, one should not force its upward movement. In this non-ascending state, though the internal Qi mechanism continues its cyclical movement of rising and falling—much like the rotation of the Big Dipper—the essential focus lies in subduing and refining through descent.

Disciple Hu Taizhen inquired: "Why must the ascending method be employed during the six Yang periods, while the descending method is used during the six Yin periods?" The answer explains: The application of fire phases (cultivation methods) must commence at the Zi hour (midnight). From Zi hour through the six Yang periods (the phase of Yang Qi generation), one must first initiate action. Because true Jing (primordial essence) tends to descend easily, it must be returned upward—hence the need for ascension. The so-called "universal ascent" refers to directing the Qi mechanism's upward movement. After the Wu hour (noon), when Yang Qi has completely returned, one need only gently nurture and maintain its flourishing state. Since the work occurs within the Qi root cavity (Dantian), while replenishing the Qi cavity to fullness, the energy will naturally descend and return to the Qi cavity—this is an inevitable principle.

The profound mystery of cultivation lies in understanding the inverted application of ascent and descent. During ascent, descent is subtly implied yet not manifested; during descent, ascent is subtly implied yet not manifested—this constitutes its essential subtlety. "Inversion" refers precisely to this reverse operation of ascending and descending movements. This has been a celestial secret closely guarded through the ages, which practitioners must comprehend. Master Chongyang (Wang Chongyang) once said: "After the Zi hour, daylight feels shorter; during Wu hour meditation, night seems prolonged"—this verifies the principle.

The fourth question: The Direct Treatise mentions the cauldron vessel referring to the lower and middle Dantian, yet we also hear of "using Qian (Heaven) and Kun (Earth) as the cauldron vessel." Are these two distinct concepts or essentially the same? The response clarifies: These are not separate concepts but different applications according to timing phases. The timing distinctions refer to: during the hundred-day foundation establishment phase for refining Jing into Qi, and the ten-month gestation phase for refining Qi into Shen (spirit) and achieving the Yang spirit. The present discussion of the cauldron vessel—where Kun (Earth/yin) refers to the hundred-day Jing-to-Qi refinement—requires gathering lower-region Qi (the true Yang essence from the kidneys) and elevating it to the Baihui point at the crown. Earth Qi inherently does not ascend spontaneously; it is through the descent of Heaven Qi (celestial Yang energy) to mix with it that, upon reaching culmination, Earth Qi is carried upward to the highest point at the crown.

This scripture expounds the methods and principles of "gathering Qi" (acquiring primordial energy) in Daoist cultivation. The so-called "upper Qi" refers to celestial energy, metaphorically representing the power of the original spirit (Shen) within the human heart. Master Xiao Zixu reveals that while the sun and moon appear in the sky, their true movement occurs beneath the earth - just as the energy from the "sea floor" (the lower Dantian in the human body) ascends upward. The mysteries of heaven-earth circulation all originate from the pivotal function of the Northern Dipper.

The Southern Song dynasty master Bai Yuchan similarly taught: Qi circulates continuously between the "Celestial Valley" (upper Dantian) at the crown and the "Yin Origin" (lower Dantian) at the perineum. When these two energies meet, they fuse into unity. This process constitutes the "return to the root and restoration of life" - the crucial point where energy reverts to its source.

Immortal Lü Dongbin (Pure Yang) emphasized that cultivation requires mastering the principles of "inverting Kan and Li" (water-fire interaction) and "the floating-sinking of metal-wood" (the ascending-descending of Yin-Yang). Here we find detailed explanations of the operational principles involving the "cauldron" (Dantian) and the movement patterns of the "medicinal substances" (Jing-Qi).

The primordial essence (Yuanjing) in the kidneys belongs to water (Kan trigram). Though fundamentally primordial Qi, it tends to flow downward and degenerate into sexual essence. During meditation it remains stored in the "Qi cavity" (Dantian), but during arousal flows toward the reproductive organs. The essential Qi of all five organs travels through spinal channels, particularly near the 24th vertebra. During intercourse, the body's energy concentrates at the waist where the five organs' Qi coalesces into semen - explaining why excessive indulgence causes lumbar pain.

The key to cultivation lies in reversing this process: making the essence ascend retrograde along the spine. This liberation from carnal habits allows recovery of primordial true Qi. The Buddhist metaphor of "pouring seawater over the crown prince's head" corresponds to the Daoist practices called "returning essence to replenish the brain" or "the nectar initiation" - both describing methods to elevate lower Dantian energy to the upper Dantian.

The teachings of bodhisattvas and Buddhas are often likened to "pouring the finest ghee on one's head" (symbolizing the most sublime Dharma revelation). Interestingly, the starting point of both Daoist and Buddhist cultivation employs this exquisite metaphor. When a person's primordial Shen (innate consciousness) becomes active, it always functions through sensory organs like eyes, ears, nose and tongue. Our intrinsic nature, like fire, tends to blaze upward, easily dissipating through these senses. Spiritual practice requires reversing this process—directing consciousness downward to unite with Jing (essence) and Qi (vital energy), collectively returning to the Dantian (the lower abdominal energy center).

The concept of "transcending the four temptations" means: when eyes aren't deluded by forms, the mind won't generate demons of material attachment; when ears aren't captivated by sounds, the mind avoids demons of auditory fixation; when the nose isn't seduced by fragrances, the heart escapes demons of olfactory craving; when the tongue isn't enslaved by flavors, the mind overcomes demons of gustatory desire. This is the state of liberation from external temptations of form, sound, smell and taste.

Buddhist scriptures record how the World-Honored One (Śākyamuni) once expounded Dharma in the Sāgara Dragon Palace—this corresponds to Daoist cultivation of the lower Dantian. Later, he entered seven-day samādhi in the Kāla Dragon Palace, mirroring the middle Dantian (heart region) cultivation stage.

Regarding Dantian cultivation principles: The lower Dantian primarily facilitates "refining essence into qi" practice. As the Thirty-Six Sacred Scriptures state, true Jing resides in the kidneys while remaining vital essences naturally gather in the lower Dantian; true Qi dwells in the heart while other energy currents converge at the middle Dantian. The Avataṃsaka Sūtra similarly describes how Buddhas emit wisdom light from their navels (corresponding to lower Dantian). Zhang Ziyang (renowned Northern Song dynasty Daoist) identified the Yellow Court (middle Dantian region) as the cauldron and energy cavities as the furnace; Wang Chongyang (Quanzhen School founder) described the navel Dantian containing a Yellow Court Palace—the ancient phrase "one point descends to the Yellow Court" refers precisely to this pivotal location.

The middle Dantian mainly serves "refining qi into shen" cultivation. Wang Chongyang metaphorically depicted this process in his Complete Perfection Anthology: like a maiden and infant playing in the middle Dantian, with energy ascending through the Hall of Light (third eye). Daoist adept Tan Changsheng emphasized that discovering our真空本性 (true empty nature) requires complete stillness of Nanshan (symbolizing the body) during deep meditation.

This scripture primarily discusses the application methods of the "Three Dantians" (upper, middle, and lower cultivation energy centers) in Daoist practice.

In the initial stage of cultivation, one must transform Jing (essence) into Yuanqi (primordial Qi), focusing mainly on the upper Dantian (head) and lower Dantian (abdomen). As Master Ziyang described, the head is likened to a cauldron while the abdomen serves as the furnace. When Jing fills the brain, proper fire regulation in cultivation will form the Golden Elixir. Bai Yuchan similarly stated that alchemical practice requires Heaven and Earth (Qian-Kun) as the cauldron-furnace, with the essence of sun and moon (the Crow and Rabbit) as the medicinal ingredients.

During the intermediate stage, the focus shifts to the middle Dantian (heart region). Master Ma Danyang emphasized that only by preventing leakage of Jing from the lower Dantian can one elevate the energy to the Crimson Palace (the heart, named for its fiery red nature) to refine the middle elixir. At this phase, the practitioner's Shen (spirit) should maintain perfect equilibrium, much like the Buddha establishing the Seven-Treasure Terrace between the realms of desire and form.

In the advanced stage of supreme attainment, attention concentrates solely on the upper Dantian (Mud Ball Palace, called Nirvana in Buddhism). Here, primordial Qi becomes fully transformed as consciousness enters a state of emptiness. The scripture stresses that the entire cultivation process follows the "Three-Field Cycle" principle: dwelling in the lower field initially, the middle field intermediately, and the upper field ultimately—just like walking, each stage requires staying precisely where one should be.

The text cites multiple masters' teachings: Lü Dongbin (Pure Yang Master) mentioned how stabilizing the middle Dantian wards off demonic obstructions; Bodhidharma taught that the key to fetal breathing (deep respiration) lies in calming the mind; the World-Honored One (Buddha) instructed practitioners to stabilize like Mount Sumeru. All these illustrate the crucial importance of properly applying the Three Dantians in spiritual cultivation.

When one reaches this stage of cultivation, the practices of "returning" (bringing Shen and Qi back to the Dantian) and "transforming spirit into Qi" (refining consciousness into vital energy) are no longer necessary. At this level, the upper, middle, and lower Dantian each fulfill distinct functional phases—a truth consistently verified by adepts across generations. Those fortunate enough to encounter this teaching should recognize it as definitive wisdom.

Someone once asked: "The cultivation method mentions 'Five Dragons Holding Up the Sage'—is this an esoteric teaching inaccessible to ordinary people, or did ancient sages never speak of it?" In truth, such metaphorical terminology has existed since antiquity. Immortals and enlightened beings frequently employed analogies when transmitting methods, driven by their profound desire to guide humanity. Directly revealing the true techniques was impractical—not only would most lack the capacity to practice them, but celestial secrets cannot be lightly disclosed. Thus, suggestive parallels were used.

For instance, the Buddha Śākyamuni described cultivation as "a reed shoot piercing through the knee." Similarly, the Quanzhen patriarch Wang Chongyang taught that when gathering the Three Treasures (Jing, Qi, and Shen), one must first circulate primordial energy via this "reed shoot" method to complete the Sevenfold Return of the Golden Elixir. Such teachings demonstrate the fundamental unity between Daoist and Buddhist cultivation. Yet later generations, misunderstanding these as literal instructions, absurdly assumed physical reeds must penetrate the knees—as if sitting in meditation could sprout actual plants!

The same principle applies to Bodhidharma’s famous allegory of "snapping a reed to cross the river." When Emperor Wu of Liang established his capital at Jinling, and Bodhidharma journeyed to Shaolin Temple in the eleventh month, no reeds remained by the riverbank to "snap." These metaphors—reeds representing spiritual methods, rivers symbolizing the turbulent sea of human desires—extend to other phrases like "the Western River flowing backward" or "the Yellow River reversing its course." Do we truly believe some foreign monk could cross oceans on reeds, or that Bodhidharma literally floated across the Yangtze on one?

Originally perceiving the "great vehicle’s aura" emanating from the East, Bodhidharma left South India to transmit the Dharma in China. Such parables guide practitioners to see beyond appearances and grasp the inner reality of cultivation. Though terminology differs, the essence remains identical.

This scripture recounts the story of how the Great Emperor Zhenwu (also known as the Mysterious Heavenly Emperor) attained the Dao. The king of Jingyue Kingdom and his virtuous Queen Shansheng dreamed of swallowing sunlight before conceiving. After fourteen months of pregnancy, Zhenwu was born at noon on the third day of the third lunar month during the first year of the Kaihuang cosmic cycle. Though born with divine prowess, Zhenwu renounced the throne to devote himself to spiritual cultivation, later receiving Daoist teachings from the Purple Void Primordial Lord, a sacred ancestor from the Jade Clarity realm.

On the ninth day of the ninth lunar month during the 57th year of the Yellow Emperor's reign (a jiazi cyclical year), Zhenwu achieved daylight ascension. The scripture specifies that Jingyue Kingdom lay beyond the seas beneath the constellation Kui-Lou, while Mount Wudang (where Zhenwu cultivated) was situated under the constellation Yi-Zhen. The term "kalpa" mentioned here refers to an immense cosmic time cycle in Daoist cosmology.

The text recounts the ancient tradition of "Five Dragons Upholding the Saint" dating back to primordial times—even during the Yellow Emperor's era, practitioners used this method to transcend worldly existence. Mount Wudang's Cliff of Body Abandonment and the Five Dragons site serve as enduring symbols for later cultivators: the cliff represents shedding the mortal form, while the Five Dragons symbolize attaining sainthood.

However, the scripture observes that ordinary people in this turbid, degenerate age often dismiss such spiritual attainments as deluded fantasies. Mired in worldly attachments and lacking cultivation resolve, they remain deaf to the true teachings of immortality. The "Five Dragons Upholding the Saint" actually represents the secret method of "piercing through the Three Passes" (a Neidan practice involving three critical energy gates in the body), entirely distinct from mundane understanding.

The text concludes by emphasizing that these cultivation methods represent the universal path to transcendence shared by all immortals and buddhas throughout history. Yet in this corrupt age, most beings remain addicted to unwholesome karma—neither possessing the will to cultivate nor the karmic fortune to encounter true immortals—thus remaining utterly ignorant of these profound mysteries.

This passage discusses the transmission lineage of the "Three Passes Secret Method" in Daoist Neidan (internal alchemy) practice. Many find this concept perplexing, yet it embodies the truth expressed by Master Chen Niwan: "The most esoteric cultivation methods are hidden in the Nine-Bend Bay."

The lineage begins with Master Zhang Jingxu, a practitioner of the Longmen (Dragon Gate) branch's "Jing" generation from the Northern School. Born during the Xuande era in Pizhou, he attained the Dao at Biyang Cave in Sichuan. Known as "Tiger-Skin Zhang" for his habitual use of tiger pelts as meditation mats, he repeatedly declined Emperor Jiajing's invitations before retiring to a stone cave at Tiger Ear Cliff on Wudang Mountain. There, he only transmitted the essential methods of reclusive cultivation to destined disciples.

Master Zhang orally transmitted these secrets to Li Xu'an (Dharma name Zhenyuan) of Lujiang County. From age 19 to 55, Li devoted himself to Daoist practice until receiving teachings on both Waidan (external alchemy) and Neidan Golden Elixirs, along with the Great Way of Celestial Immortality, ultimately achieving spiritual realization.

Li Xu'an then instructed Cao Huanyang (Dharma name Changhua) of Nanchang. After relinquishing his family wealth for spiritual pursuit, Cao attained the state of "transforming consciousness into samadhi" while practicing the "Five Dragons Upholding the Sage" method, finally achieving the Yang Spirit realization during wall-gazing meditation at Western Mountain in Xinjian County.

Ultimately, Master Cao Huanyang transmitted this complete method to me and your father, Zhenyangzi (Dharma name Shouxu). Any cultivation practitioner who comprehends and implements this method can verify the state of deathless longevity, transcend the cycle of rebirth, and attain boundless spiritual powers. Without understanding this principle, one remains forever bound to the mundane world.

This scripture recounts the miraculous deeds and spiritual attainments of several Ming Dynasty Daoist practitioners.

First, it mentions several cultivators from the Western Mountains region, including Xiong Xiu'an (Daoist name Shouxu) and Deng Shaoyuan (Daoist name Shoukong). After hearing the essential cultivation secret of "birth, death, and reincarnation," they all attained supernatural abilities to aid the world and save others. Among them, the story of Master Li stands out: during a severe drought, he merely smeared ink on his palm, silently recited incantations toward the sun, and summoned dark clouds and heavy rain, relieving the drought across six counties. He could also effortlessly lift massive boulders weighing five or six thousand jin.

Later, a greedy county magistrate sought the secret of immortality from Master Li. When refused, he harbored resentment and sent men to capture him. Master Li then feigned death (known in Daoism as "shijie," or liberation from the corpse), lying in a coffin for seven days before mysteriously vanishing. In truth, he had long attained the state of "marvelous union of form and spirit" (xingshen shuangmiao) and was simply living in seclusion at a relative's home. When the new magistrate heard of this, he praised Master Li as a "bodhisattva in the flesh."

Finally, another practitioner named "Huanyang" is mentioned. After hearing this secret, he achieved immortality, reaching the state of "embracing the radiance of the great void, wondrously awakening to the infinite" (han guang taixu, miao jue wuji). He could "project his yang spirit" (chu yangshen), allowing his primordial spirit to leave his body and enter the eternal stillness of the "infinite void" (wuji).

Through these stories of cultivators, the scripture illustrates how genuine practitioners often conceal their supernatural abilities rather than flaunt them. It also satirizes local officials who abuse their power, covet immortality without understanding the cultivation of the mind.

This passage documents the transmission lineage of the Daoist cultivation method known as "Five Dragons Presenting the Sacred" (Wulong Pengsheng). During the Tianqi era of the Ming dynasty (1621-1627), a recluse dwelling in the Western Mountains first recorded the term "Five Dragons" in writing. On his deathbed, his master Cao specifically transmitted the secret formula: "Five Dragons Presenting the Sacred, the Priceless Mechanism of Ten Thousand Gold," emphasizing this as the supreme method for achieving immortality, requiring purification rituals, incense offerings, and sacred oaths before transmission.

While ancient traditions held that celestial methods shouldn't be committed to paper, the author explains that since his master had already recorded it in writing, he continued this textual transmission. This method is considered the crucial watershed in mortal cultivation—without understanding it, practitioners might cultivate for lifetimes without transcending samsara. Addressing skeptics questioning the "Five Dragons" concept, the author cites two evidences: the legend of Five Dragons Presenting the Sacred at Wudang Mountain's Shentian Cliff, and the Buddhist account of Bodhidharma "crossing the Yangtze on a reed." The text further notes that Quanzhen patriarch Wang Chongyang's works already contained references to similar practices like "Reed Sprouts Piercing Knees" (Luya Chuanxi) and "Dual Cultivation of Water and Fire" (Shuihuo Shuangxing), all verifiable in the Daoist Canon (Daozang).

(Note: "Five Dragons Presenting the Sacred" is a Neidan (internal alchemy) term describing the method of gathering Qi from the five viscera to the Dantian (energy center); "Reed Sprouts Piercing Knees" metaphorically describes the meditative experience of Qi penetrating the knee joints during seated practice.)

This passage primarily discusses the concept of "nurturing the embryo" (养胎) and meditative practice in Daoist cultivation. It first mentions the Buddhist scripture Five Dragons Sutra (《五龙经》), which distinguishes between wordless scriptures and those with words, indicating these classics are not empty fabrications but contain genuine substance.

Regarding the question of "nurturing the embryo," it explains this is actually a metaphor referring to the stage of refining Qi into Shen (炼气化神) during cultivation—there isn't an actual fetus involved. As stated in the Supreme Lingbao Great Vehicle Wonderful Dharma Lotus True Scripture (《太上灵宝大乘妙法莲花真经》), maintaining mental clarity undisturbed by external phenomena constitutes "purity" (清), while stabilizing the Shen and Qi in stillness represents "tranquility" (静).

Though termed "nurturing the embryo," it essentially describes the initial cultivation stage of achieving a breathless state resembling a fetus in the womb. Beginners cannot immediately attain complete breathlessness but must gradually practice entering meditative absorption (入定). This parallels how fetuses only begin breathing just before birth—similarly, when practitioners first meditate, both the arising/ceasing of thoughts and the movement of breath remain present.

When deluded thoughts arise, this constitutes the "arising phase" (生相); their elimination forms the "cessation phase" (灭相). As Master Anguo remarked while reading the Śūraṅgama Sūtra (《楞严经》): "The establishment of perception is the manifestation of arising and cessation." Beginners cannot immediately transcend these phases. Since mental arising/cessation affects breathing, practitioners must stabilize their Shen and Qi through methods like "preserving Shen to gather Qi" (存神摄气) and "retaining Qi to sustain Shen" (存气留神).

This practice is termed the "Two Vehicles" (二乘, referring to Hīnayāna and Mahāyāna Buddhism) or "Tathāgata" (如来, Buddhist term meaning "thus come"), implying "coming according to principle and departing according to principle." Here, "coming and going" refers to the inhalation and exhalation of breath—the fundamental principle of meditative cultivation.

The Avatamsaka Sutra states that the great immortal path of the Tathagata (a title of the Buddha) is subtle and profound, difficult for ordinary people to comprehend. Dipamkara Buddha (one of the past Buddhas) also taught: All phenomena in the world are subject to impermanent change—where there is birth, there must be cessation. This expresses the same principle.

When one enters nirvana (the state transcending the cycle of birth and death) but has not yet attained complete enlightenment, the Buddha calls this "nirvana with remainder." Practitioners gradually deepen their realization from this stage onward, a method known as the gradual cultivation approach.

Immortals and sages use the metaphor of "nurturing the embryo" to describe this cultivation process. The Embryonic Breathing method (a type of breath cultivation) teaches that when the mind is tranquil and settled, the spirit (Shen) gathers, and the breath stabilizes—only then can the "embryo" grow. The embryo's development relies on the steadiness of breath; without breath, there is no embryo, and without the embryo, breath cultivation cannot be discussed.

The Treatise on Embryonic Breathing points out: If distracting thoughts arise in the mind, true Qi will dissipate, causing the embryonic breathing practice to fail—how then can one attain the Dao? To reach the breathless state of the Cessation of Perception and Feeling (the highest meditative absorption), it is like when male and female first unite—though Yin and Yang Qi merge, the embryo has not yet formed, existing in a state of undifferentiated emptiness. At this stage, the phenomena of birth and cessation vanish.

Only through prolonged cultivation across the Four Dhyanas (four meditative states) can one reach the realm where "birth and cessation themselves cease" (transcending the cycle of life and death). This is what the Sixth Patriarch Huineng called "the meditative mind is without thought, the meditative nature is without birth." When all signs of inhalation and exhalation completely subside, one attains the Cessation of Perception and Feeling. At this point, the mind reaches the state of neither arising nor ceasing, the body becomes the deathless form, and both spirit and form enter the mysterious realm. The Sixth Patriarch also said: The mind is the land, the nature is the king—the king dwells upon the land of the mind. When nature is present, body and mind endure; when nature departs, body and mind decay.

Upon reaching this state, the practitioner suddenly merges with emptiness. Zhang Ziyang (a renowned Daoist master of the Northern Song dynasty) taught: One should feel as though the body exists within emptiness—maintaining this state consistently is true meditation. Thus, immortals and sages call this "the embryo matures," while the Buddha calls it "nirvana without remainder" (complete liberation). "Without remainder" means both mind and breath have utterly ceased.

Thereafter, one may shed the embryo and manifest the spirit (the Yang spirit leaves the physical body)—this is the natural emergence from absorption after meditative attainment, which the Buddha calls "the appearance of the Tathagata." The Shurangama Sutra states: It is like wandering within the womb of the Dao—this parallels the immortal tradition’s metaphor of pregnancy. Just as a fetus develops into a complete human form, this symbolizes the perfection of meditative attainment, the completeness of consciousness, and the profundity of spiritual wisdom. As body and mind increasingly fuse and grow, ultimately, form and spirit both reach sublimity, and one sheds the embryo to emerge as a true awakened being. The immortals call the pure Yang spirit cultivated to the point of transcending the body a "divine immortal," while Buddhists refer to it as the attainment of great absorption.

This scripture discusses the realm of "sudden enlightenment" (顿悟) in the cultivation of immortals and buddhas. Practitioners Shi Taisu and Hu Taizhen raised the question: When Daoist cultivators achieve "yang-shen liberation" (出阳神, the spirit leaving the body) and Buddhist practitioners attain "emergence from samadhi" (出定), can this be considered complete perfection? Why do the classics mention an even higher state called the "Genuine Sudden Enlightenment Gate" (真圆顿门)?

The response clarifies that many contemporary practitioners misunderstand "sudden enlightenment," mistakenly believing it can be attained at the initial stage of cultivation. This is incorrect. The authentic Sudden Teaching of the Great Vehicle (顿教大乘), as described in the Avatamsaka Sutra (《华严经》), manifests only when the Tathagata reveals the Sambhogakaya (卢舍那身, Buddha's reward body) in the field of perfect stillness while expounding the complete Dharma. Similarly, the Sutra of Perfect Enlightenment (《圆觉经》) explains that the Tathagata's state—attained through gradual cultivation until Buddhahood—is what truly constitutes the Sudden Teaching.

The text particularly emphasizes the sequential stages of cultivation: from the First Ground (初地) to the Seventh Ground Bodhisattva (七地菩萨), diligent practice is essential. Only upon reaching the Eighth Ground (八地) and beyond does intentional effort become unnecessary. Those who abandon practice before reaching the Seventh Ground risk falling into the heterodox view of "annihilationist emptiness" (断见空亡), while those who forcibly continue cultivation after the Eighth Ground err like those who leave the feast prematurely. Many practitioners stumble into these two deviations and consequently fall into demonic paths.

Authentic complete cultivation must traverse the full progression from the First Ground to the Eleventh Ground (等觉, equal enlightenment), ultimately reaching absolute perfection. This constitutes the genuine Sudden Teaching. Contemporary ordinary people who claim sudden enlightenment without having attained the state of perfect stillness are merely indulging in self-aggrandizement and worldly fame—behaviors characteristic of demonic paths.

This passage addresses common misconceptions about "embryo formation" and "external bodies" in Daoist cultivation practices. It first critiques the naive belief that practitioners physically grow an infant in their abdomen during meditation, which eventually becomes a separate physical body—a notion deemed utterly foolish. The text clarifies that the "embryo" in cultivation refers not to a biological fetus but to the state of "embryonic spirit" (taishen) achieved through refining one's innate nature.

Regarding the concept of "a body beyond the body," the author explains: Human true nature is formless and spiritually dynamic, without fixed physicality. The supernatural abilities attained through deep meditation (samadhi) fundamentally represent unity with the void, not the literal creation of a tangible double. Those who attain the Dao merge with emptiness itself, gaining infinite transformative capacities. However, the spiritual manifestations during initial meditative states remain relatively weak, requiring a nurturing phase called "lactation" (continued cultivation) to achieve full metamorphic potential.

The text distinguishes two cultivation outcomes: The "yang spirit" arises when primordial essence (yuanjing) harmonizes with genuine nature cultivation, enabling miraculous manifestations. By contrast, the "yin spirit" results from meditative attainment alone without vital essence integration. The yang spirit possesses transcendent capacities—perceiving the imperceptible and creating the unimaginable—far beyond ordinary human limits.

Quoting the Divine Mirror of the Cavernous Numinous (Dongling Shenjian), the passage concludes: Spiritual manifestations correlate with mental activity—appearing wherever intention flows, withdrawing when stillness returns. Like Buddhism's skillful means (upaya), their purpose is guiding seekers toward the Dao rather than fixating on concrete "external body" forms. Authentic cultivation lies in returning to the formless origin, not pursuing external marvels.

The spiritual powers that ordinary people can visibly manifest in the physical world are called Yang Shen (the luminous spirit). If one cannot manifest a concrete form in the material realm—remaining invisible and intangible to others, unable to make the nonexistent appear or the existent disappear—this indicates a deficiency of primordial Yang Qi (innate pure Yang energy). Merely possessing foresight beyond ordinary people or occasionally manifesting in shadowy places constitutes what is called Yin Shen (the shadow spirit). Yin Shen is entirely opposite to Yang Shen in nature, and thus its spiritual powers are inferior to those of Yang Shen.

The foundation for achieving Yang Shen lies in Yuan Jing (primordial essence, the pure Yang energy) and Zhen Yang Qi (true Yang energy). Yuan Jing is formless, qualityless pure Yang energy capable of transforming and replenishing Zhen Qi (true energy), nourishing Yuan Shen (primordial spirit), and ultimately forming the Golden Elixir (the supreme achievement of Neidan practice). This leads to attaining the Dao of immortality and manifesting miraculous transformations—this is the genuine Yang Shen. If the cultivated Qi lacks the pure, formless Yang quality, it becomes turbid Yin energy, devoid of dynamic transformative capacity. Even if one reaches the realm of emptiness, it remains merely Yin Shen, for without the fundamental pure Yang energy, the result cannot be Yang Shen.

Sun Buer (a female Daoist master and disciple of Quanzhen founder Wang Chongyang) once said: "If one emphasizes only Xing cultivation (spiritual nature) while neglecting Ming cultivation (vital essence), nine out of ten practitioners will fall into stagnant emptiness (a mistaken state of vacuous nothingness)." One must practice the dual cultivation of nature and life (Xing and Ming simultaneously), where the "foundation of life" refers precisely to the true Yang primordial essence. It's like using wheat flour to make baked cakes—this is the fundamental principle.

Xu Fuyang, a lineage holder of Qiu Chuji (another of Wang Chongyang's disciples), cautioned: "Before achieving the returned elixir (the process of refining primordial essence into the Golden Elixir), one must never force inner observation (Neiguan meditation), lest one develop Yin Shen and stray from the true path." The so-called returned elixir requires seizing the moment when primordial essence stirs, using reversal methods to transform it into the Golden Elixir. Only after the Golden Elixir coalesces can it nourish the primordial spirit, enabling one to enter meditative absorption and ultimately transform into Yang Shen. Forcing inner observation without first achieving the Golden Elixir is like building a house without foundations—it inevitably leads to the perilous state of empty extinction (a dangerous deviation in practice).

Yin Shen is essentially the residual consciousness after physical death, similar to a ghost. "Taking residence" refers to this consciousness reincarnating after the body's death, like moving to a new dwelling. "Losing the true Dao" means straying from the orthodox path of achieving immortality through Yang Shen.

Practicing only dry meditation (sitting without alchemical cultivation) may bring temporary insights, and immediately applying inner observation methods might enable relinquishing all attachments, even to the point where breathing seems to cease (reaching the extinction samadhi state). Yet the arising and ceasing of thoughts never truly stops.

When the mind attains meditative absorption, all delusive thoughts are extinguished (this state is called "nirodha-samapatti"). The Huangjing Jizhu states: When delusions arise, hell manifests; when delusions cease, hell vanishes.

Only by reaching genuine emptiness and clarity can one cultivate the Yin Spirit (a preliminary form of spiritual consciousness). Both the mind and breath must enter a state of true emptiness to achieve this, which is why Master Changchun said: Without attaining true emptiness, even the Yin Spirit cannot be realized. This shows that cultivating the Yin Spirit is no simple feat.

Yet the Yin Spirit remains a minor achievement—still bound by birth and death, unable to escape the cycle of reincarnation. Where there is death, there is rebirth; without immortality, one remains trapped in samsara, possibly falling into the three lower realms: hell, hungry ghosts, or animals. Even rebirth as a human or ascent to heaven is ultimately just another turn in the wheel of rebirth.

Those who only reach the Four Fruits (the four stages of Hinayana practice) may ascend to heaven or be reborn as humans, but once their heavenly blessings are exhausted, they will still fall. The Huangjing Jizhu notes: Those who ascend through accumulated merit will inevitably decline when their merit runs out. Thus, Master Zhang (Zhang the Tiger-Skin Seated) compared this state to a "false flower"—one that blooms but bears no fruit, far inferior to the substantial achievement of cultivating the Yang Spirit (the higher spiritual consciousness).

When Master Li Xu'an learned the inner observation method (neiguan) from Liu Baozhu of Shandong and practiced it continuously for forty-nine days, he indeed experienced the light of wisdom (a luminous state attained in practice), even seeing through city walls as if they were transparent crystal. He mistook this for the wondrous proof of harmonizing mind and breath, yet upon exiting meditation, he remained an ordinary man, seeing nothing. Master Zhang called this the classic example of a "false flower bearing no fruit."

When the Yin Spirit exits the body, the light of wisdom does appear, allowing one to perceive distant things as if they were right before the eyes—a rudimentary form of the divine eye (one of the six supernatural powers). Walls and buildings pose no obstruction; mountains, rivers, and city walls cannot block the vision. Though the body remains in one place, the luminous awareness extends far. But take care: this is not about leaving the body to chase external phenomena, or one risks falling into a deluded, dreamlike demonic state, mistaking illusions for Yin Spirit attainment. Clinging to this will lead to demonic paths.

The Shurangama Sutra warns: If one falsely claims to have attained enlightenment, it disrupts meditative purity, turning one into a demon of love and views (a demonic hindrance obsessed with illusory states), losing the root of Buddhahood. Like a poor man claiming to be an emperor, this act of declaring attainment without realization is a grave taboo in practice.

Some claim to be able to project their yin-shen (astral spirit) to wander marketplaces, attracting admiration and belief from others. In truth, a genuine yin-shen radiates luminous wisdom, perceiving all things without obstruction—how could it only see market streets while failing to penetrate the walls of adjacent buildings? Such experiences are nothing but spring dreams, certainly not authentic yin-shen manifestations. Those who boast of such abilities are deliberately deceiving the world to gain fame, conduct utterly unworthy of virtuous practitioners. This behavior violates both the precepts of the Dongxuan Lingbao scriptures and the four Vinaya rules of the Śūraṅgama Sūtra, requiring utmost caution from cultivators. Transgressors face punishment by the Female Blue-Law Wind Blades (a Daoist underworld torment) or descent into the Tongue-Extraction Hell of Fengdu Mountain (a Buddhist infernal retribution).

Those who exploit others' credulity to boast of yin-shen abilities are truly shameless. A genuine yin-shen possesses only five supernatural powers: divine mobility (free transformation), knowledge of past lives, mind-reading, celestial hearing (perceiving all sounds), and celestial vision (unobstructed perception). The yang-shen (pure yang spirit) of immortals and buddhas possesses all six powers, while yin-shen—being yin-energy dominant—always lacks the sixth power of cessation (extinguishing lustful desires). The so-called "five-power ghosts" in worldly parlance precisely refer to such beings, who often harm women due to unresolved lust, eventually exhausting their jing (vital essence) to become hungry ghosts.

The Tai Xiao Lang Shu records: The Great Ultimate Master explicitly states that those possessing only five powers remain within the Triple Realm's cycle of rebirth, not yet true immortals. Authentic Daoist transcendence surpasses the boundaries of "being" and "non-being," dwelling freely in the in-between state beyond all constraints, thereby escaping the Triple Realm. Those yin-shen still bound by birth and death are ultimately neither immortals nor buddhas.

Some individuals nowadays claim to be able to project their Yin-spirit (referring to soul projection) to deceive others, yet they are far from attaining the five supernatural powers of the Yang-spirit (the pure, undefiled primordial spirit). Most critically, they lack the supreme ability of "exhaustion-free transcendence" (the power to sever all afflictions and permanently transcend the cycle of life and death).

Only by preserving one's Yang-essence (primordial Qi) without leakage can one achieve exhaustion-free transcendence. Once this power is attained, it forms the foundation for immortality and becoming either a celestial immortal or a Buddha. If one cannot control the leakage of essential vitality, exhaustion-free transcendence remains unattainable, making it impossible to achieve eternal life and inevitably trapping one in the cycle of rebirth. Ignorant people fail to understand the truth that life inevitably leads to death, and death inevitably leads to rebirth. Instead, they foolishly believe in deceptions and pursue mortality—this is the folly of actively throwing oneself into the cycle of reincarnation.

Authentic Buddhas like Śākyamuni first attained exhaustion-free transcendence before achieving immortality and liberation from rebirth. As stated in the Scripture of the Supreme Secret True Treasury: "Cultivation requires single-minded focus." Sentient beings afflicted by worldly attachments within the Three Realms can never attain awakening without proper methods.

Practitioners like Asita and Kātyāyana mentioned in Buddhist texts, though they achieved the four meditative absorptions and five supernatural powers, lacked exhaustion-free transcendence precisely because they failed to purify sexual desire and allowed their Yang-essence to leak. Consequently, they only cultivated Yin-spirit (consciousness tainted by Yin-energy). The Yin-spirit is the product of failed Yang-essence cultivation—when Yang-essence remains unspent, one does not die; when it leaks, death is inevitable, and the deceased becomes a Yin-ghost. As Confucianism states, "Ghosts are the numinous manifestations of Yin-energy," and the Scripture of the Primordial Nine Elders similarly warns: "Those who cannot preserve their vital life force will degenerate into lower ghostly beings."

Those who attain clairvoyance or clairaudience may perceive worldly phenomena but cannot access celestial realms beyond the Form Realm, precisely because they lack genuine Yang-essence and Qi, preventing their union with the purely Yang Heavenly Dao. As the Jade Instructions of the Three Sovereigns declare: "Yang represents the Heavenly Dao. Only when spirit and Qi unite with the Dao can one become a divine immortal." The crucial method for cultivating the path of celestial immortality lies in refining essence into Qi to achieve a body of pure Yang.

This scripture expounds the essential principles for attaining immortality and Buddhahood, focusing primarily on the transformative relationship between Jing (essence), Qi (vital energy), and Shen (spirit).

It first clarifies that yang essence (the body's innate primordial Qi) constitutes the foundation of longevity. Without understanding the method to obtain yang essence, one cannot establish the basis for celestial immortality. The text emphasizes the necessity of genuine comprehension regarding the timing, location, and techniques for "gathering the medicine" (collecting primordial Qi) and "refining the medicine" (transforming Qi), with each step requiring authentic practice. Those obsessed with debauchery or solely cultivating yin spirit (while neglecting yang energy cultivation) can never achieve immortality or Buddhahood.

The crux of cultivation lies in transforming essence into energy and energy into spirit. When practitioners refine Qi to its ultimate state of stillness, it transforms into Shen, enabling transcendence beyond life and death. However, if Qi remains incompletely refined, one still belongs to the realm of form (the material world). True enlightenment requires complete transformation of essence into energy, and energy into spirit, reaching the state where "energy stabilizes and spirit becomes unobstructed."

The Dao of yin-yang union refers to the cultivation method of unifying spirit and energy into oneness. When energy reaches the state of extinction (nirvana-like stillness) and spirit enters profound tranquility, their union leads to the attainment of spiritual fruition. During deep meditation, the mind merges with the Great Void (cosmic origin), where the nature-body achieves perfect luminosity, unbound by any dharma realms or worldly constraints. Yet only those who have cultivated yang spirit (pure yang consciousness) can attain this state—those who haven't must still rely on foundational practices like embryonic breathing.

When yang spirit manifests, one gains supernatural powers encompassing heaven and earth. After yang spirit emerges from the body, it transcends material form, surpassing the meditative states of the form realm. At this stage, all active cultivation practices are complete, entering the phase of wuwei (non-action) governance characteristic of immortal and Buddhist fruition. "Penetrating heaven" signifies ascending through the twenty-four heavens of the desire and form realms—like the Buddha's white curl light reaching Akanistha Heaven (highest form realm), representing the divine eye's power. "Piercing earth" denotes omniscient awareness of all lower worlds.

This scripture describes the supernatural abilities attained by those who reach profound levels of cultivation. Practitioners can clearly perceive the underworld realms—including the twenty-four hells, eighteen hells, and eight great hells—and hear the voices of beings suffering there, much like how the Buddha's white curl between his eyebrows illuminated the eighteen hells. This ability is called "divine realm penetration" (shenjing tong), enabling unobstructed perception of all phenomena.

Cultivators also gain insight into cosmic space-time: spatially ("yu"), they observe multiple dimensions like the Desire Realm, Form Realm heavens, and hells; temporally ("zhou"), they comprehend past and future events, known as "knowledge of past lives" (suming tong). More remarkably, they can alter celestial movements, as demonstrated by these historical examples:

• During the Han Dynasty, Luan Ba sprayed wine at court that transformed into rain, extinguishing a great fire in Chengdu.
• The Tang Dynasty monk Yixing captured seven pigs in a cloth bag, causing the Big Dipper to vanish (as the Dipper Deities had taken porcine forms).
• When Mars threatened disaster during Qiu Chuji's stay in Beijing, the Quanzhen patriarch's prayers made the planet retreat.
• Ming Dynasty adept Zhang Jinghe (Iron-Crowned Daoist) altered wind directions to help Zhu Yuanzhang's warships sail upstream.
• Zhang Sanfeng extended his disciple Li Xuan's lifespan by twelve years by modifying the celestial records of the Dipper Deities.
• Li Xuan ended a drought by shading the sun with ink-blackened palms, summoning rain that saved six counties.

These miracles of bending natural laws demonstrate the marvelous functions of "true yang-spirit" (zhen yangshen)—the supreme state of unity with cosmic emptiness. At this stage, practitioners become one with the Dao (the Way), wielding the creative forces of heaven and earth at will.

Master Wang Yuyang (one of the patriarchs of the Quanzhen school) said: Once one comprehends the realm of true emptiness, one fully understands the principles of attaining immortality. Master Wang Chongyang (founder of Quanzhen Daoism) also pointed out: Only those with thoroughly awakened spiritual nature can become Great Luo Golden Immortals - those who fail to realize their original mind and true nature cannot attain genuine emptiness.

What we call "seeing one's true nature" refers to the fundamental stillness of human nature, free from the cycles of birth and death. When practitioners achieve constant stability through mind cultivation, they realize the true face of their original nature - this is precisely the state of becoming immortals or buddhas. Master Yu Qingfeng emphasized: Without realizing true emptiness, the yang-spirit (cultivated primordial spirit) cannot manifest. Master Tan Changzhen wrote in his Water-Cloud Collection: "To ascend the immortal path in this lifetime, one must align with the Dao of emptiness - otherwise, immortal attainment is impossible."

The phrase "failing to achieve yang-spirit" refers to what the Sixth Patriarch Huineng described as "cultivating to the state of unmoving suchness, eternally still like inanimate objects - this is true yang-spirit attainment." Without realizing the true emptiness of one's nature, it's absolutely impossible to refine the yang-spirit. When cultivation reaches the stage of mind-realization and nature-awakening, this original nature manifests as yang-spirit during post-meditation states, displaying spiritual powers. If one hasn't achieved buddhahood through nature-realization, it means the yang-spirit remains unformed and cannot manifest. Forcing spiritual projection while residual thoughts remain is merely mental distraction, indicating insufficient meditative stability.

Someone asked: How to discern genuine realization of true emptiness and authentic yang-spirit manifestation? The answer: When mind-nature completely merges with emptiness without attachment to spiritual powers or wondrous functions. The Primordial Heavenly Virtue Scripture states: "The supreme wondrous Dharma has no cause; the mysterious state requires no external conditions." The Sixth Patriarch also said: "Meditative mind has no distractions; meditative nature is originally unborn." Here, not a single dust-mote remains, not a single thought arises - complete transcendence beyond the cycles of coming and going, birth and death. The Primordial Virtue Scripture notes: "Only by transcending life and death can one attain eternal life" - this is the true manifestation of the emptiness realization.

If the mind-nature still harbors wandering thoughts, attachments or external disturbances, one cannot maintain embryonic respiration (the state of primordial breathing). Breathing that still involves inhalation and exhalation belongs to ordinary people, indicating unsettled original nature. Only by extinguishing all external conditions and worldly thoughts, completely returning to the constant abode of embryonic respiration in samadhi, thoroughly transcending the movements of breath and transformations of birth-death - this is the fundamental principle of immortal-buddha meditation. Genuine true emptiness means the original mind no longer produces wandering thoughts, true breath becomes completely still, with no more movement of coming and going - therefore called "true." If thoughts aren't fully settled and breathing not completely ceased, the cycle of birth and death remains - this cannot be considered genuine realization. The "solid ground" isn't empty talk but tangible cultivation achievement.

This passage primarily discusses the importance of achieving "true emptiness" (a state of complete stillness) in spiritual cultivation, as well as the principle that celestial secrets in the transmission of immortal and Buddhist teachings should not be lightly revealed.

Master Chongyang (Wang Chongyang, founder of the Quanzhen tradition) taught that to perceive true emptiness, one must trace back to the fundamental state of primordial nothingness (the most original condition of the universe). When cultivation reaches its ultimate stage, the phenomenon of "celestial flowers scattering in profusion" will manifest. At this point, the original spirit (Shen, the higher form of life attained through cultivation) will emerge from the crown of the head, transcending physical limitations to enter more advanced stages of practice, ultimately merging with the Great Dao.

The Wushang Neimi Zhenzang Jing (Scripture of the True Treasury of Supreme Secret Inner Teachings) states that the true Dao transcends all concepts and severs all attachments—it is without thought, without consciousness, without perception, without observation. This is the genuine Dao. The true Dao is utterly quiescent, to the extent that even the notion of "quiescence" must be relinquished.

Some may ask why ancient sages rarely mentioned states like "celestial flowers scattering in profusion." This is because celestial law strictly forbids the casual disclosure of core cultivation secrets. The true essence of orthodox immortal and Buddhist methods is rigorously guarded by cosmic principles and cannot be recklessly revealed to the arrogant and ignorant. However, for the salvation of sentient beings, celestial mandate may occasionally permit slight revelations—the wise may thereby attain enlightenment, while the foolish might fabricate false teachings to mislead others.

This resembles the common saying: "Establishing one method breeds one abuse." Out of compassion for the multitudes being misled, the "Five Dragons Method" (an advanced cultivation technique) has now been disclosed. Yet there remains concern that wicked individuals may later devise false methods to deceive people. Thus, lineage patriarchs like Bodhidharma, Shenguang, Chongyang Zhenren, and Qiu Chuji (Changchun Zhenren) all transmitted these true teachings only after careful deliberation.

Future seekers of the Dao should have faith in these clearly recorded truths—those capable of understanding will naturally comprehend. Those who cannot immediately grasp them should await personal transmission from immortal masters, never heeding the lies of charlatans. Some fail to understand due to shallow spiritual roots and lack of immortal karmic connection. For instance, the Song Dynasty Daoist Lan Yangsu practiced at Mount Heng for ten months with initial success but remained stagnant long-term due to lacking authentic transmission.

This passage particularly emphasizes that genuine cultivation requires complete relinquishment of all attachments—even the notion of "relinquishment" must be released. It also clarifies that authentic cultivation methods require orthodox transmission; one must not lightly believe in heterodox paths, lest they stray onto wrong roads.

This passage discusses the critical state of "emerging yang spirit" (the primordial spirit leaving the physical body) in Daoist cultivation, along with the core perspective that the practices of immortals and Buddhas share the same essence.

When Patriarch Liu Haichan received Li Yuxi's ten contemplative poems, he laughed heartily and manifested his transcendence. Like the celestial flowers scattering when the Buddha preached—this phenomenon actually serves as crucial guidance for practitioners. When the Second Patriarch Shenguang (Chan Patriarch Huike) expounded the Dharma, celestial flowers also descended, yet he still worried about not having truly transcended the bonds of life and death.

The descent of celestial flowers marks the pivotal moment distinguishing sages from ordinary beings: those who immediately emerge from meditation upon seeing the flowers transcend life and death to become realized sages; those who remain in meditation despite witnessing them remain ordinary beings bound by mortality. Sages master their own life and death, while ordinary people remain subject to Yama's (Lord of the Underworld) control.

This was precisely the transcendent state Patriarch Bodhidharma sought when severing his arm for the Dharma. When Zhongli Quan (one of the Eight Immortals) spoke of "thunder shaking the celestial gate startling ghosts and deities," he described the experience of the primordial spirit exiting—when the heavenly gate (crown point) vibrates like thunder. "Overturning the cosmos to fly with white snow" depicts the omen preceding the yang spirit's emergence—one must witness this vision before the spirit can properly depart, otherwise no rash action should be taken.

Lü Dongbin (the Pure Yang Perfected) used "cold clouds dispersing to reveal the waning moon" to symbolize the meditative state where embryonic respiration (innate breathing) completely ceases; "when the year's end arrives, return to the Great Void" means that upon seeing snowflakes fall, one must abandon the illusory physical form and return to emptiness.

Wang Chongyang (founder of the Quanzhen school) described sudden tremors accompanied by showering celestial flowers as heralding a Perfected Being's manifestation. Qiu Chuji (the Eternal Spring Perfected) clarified that only when celestial flowers dance across the heavenly court does it signify the yang spirit's emergence and attainment of the initial fruition (preliminary accomplishment in cultivation).

All practitioners initially attaining immortal or Buddhist fruition experience identical visions, proving their practices share the same essence: both require refining jing into qi, transforming qi into shen, and returning shen to emptiness. Buddhism's emphasis on observing celibacy and cultivating pure conduct to transcend the desire realm corresponds to Daoism's preservation of jing for nurturing life; Buddhism's four dhyanas extinguishing afflictions parallel Daoist embryonic respiration stabilizing the spirit; the seventh bhumi bodhisattva state equals Daoism's supreme realm of refining spirit to return to emptiness.

When Shi Taisu and Hu Taizhen asked: "If immortal and Buddhist cultivation are identical, why does Buddhism emphasize cultivating samadhi by leaving the 'palace' (mundane world), while Daoism focuses on seeking the mysterious in the 'water palace' (kidney jing)?" The response clarifies this distinction stems from ordinary understanding—all truly realized sages know their fundamental unity.

This scripture primarily discusses the common ground between Daoist cultivation and Buddhist practice, as well as common misconceptions about them.

When practitioners progress from the eighth bhūmi (bodhisattva stage) to Buddhahood, they receive empowerment (divine protection) that gradually elevates them through the ninth and tenth bhūmis until reaching the eleventh stage of "equal enlightenment" (approaching Buddhahood), which already transcends the formless realm (highest of the three realms). Whether cultivating the Dao or pursuing Buddhahood, following this method can lead to corresponding attainments. The key lies in whether practitioners can hear, believe, and comprehend this principle—otherwise, there can be no talk of achieving immortality or Buddhahood.

Currently, two erroneous views prevail in the world: One claims "instant attainment," which actually only refers to avoiding evil realms at death's door, not genuine realization of the immortal or Buddhist path. The other speaks of "immediate karmic redirection," meaning rapid rebirth after death to avoid falling into evil paths. These belong to the most elementary levels of cultivation—the cycle of seven heavenly and seven human rebirths that represent the initial stages for both immortals and buddhas.

People often divide immortals and buddhas into opposing schools, when in truth their cultivation methods, spiritual states, and realized fruits are identical. Superficial observers know only that Daoism speaks of "emptiness" while Buddhism discusses "extinction," unaware that the Daode Jing (Classic of Dao and Virtue) already expounded the principle of extinction. They recognize Daoism's dual cultivation of nature and life (xingming shuangxiu), while Buddhism emphasizes seeing one's nature, yet fail to understand that without seeing one's nature, no one can become an immortal. These misunderstandings stem from ignorance of the truth.

Since the Sixth Patriarch of Chan Buddhism ceased transmitting the robe and bowl, Buddhist teachings on mind-nature (xingxue) lost their purity. Many monks discuss only the coarse principles of rebirth and transmigration without investigating the Tathāgata's true nature that transcends samsara, thus artificially dividing immortals and buddhas into separate schools. Although Buddhism...

This scripture primarily discusses the similarities and differences between Daoist and Buddhist cultivation methods, as well as the relationship between the two paths of "gradual cultivation" and "sudden enlightenment."

Under the Fifth Patriarch Hongren, the tradition split into two schools: Shenxiu advocated the "Northern Gradual Method" (step-by-step practice), while Huineng (Lu Neng) founded the "Southern Sudden Method" (instantaneous awakening to Buddhahood). Just as Buddhism developed different schools in China, it's natural that Eastern Daoism and Western Buddhism would have distinctions. Yet practitioners often cultivate blindly, falsely claim enlightenment, and forcefully divide traditions to promote themselves.

The author, Great Unity Zhenren (Taiji Zhenren), raises a question: Ancient immortals all emphasized "unity" to dispel worldly confusion, while Buddhist monks constantly divide into sects and mislead followers. Why didn't the ancients correct this mistaken categorization? Why wasn't the principle of "unity" clearly explained in Buddhist scriptures? This has led modern people to doubt both ancient and contemporary teachings.

The response explains: Cultivation must begin with "conditioned methods" (specific practices) before ultimately reaching the "unconditioned" (Wuwei, natural perfection) state. Daoist master Zhang Boduan (Zhang Ziyang) states in Awakening to Reality (Wuzhen Pian) that practitioners should work silently in the beginning—only at the unconditioned stage will others recognize their attainment. The Buddhist monk Sengzhao also said that while conditioned methods are provisional, abandoning them completely makes Buddhahood impossible; though the unconditioned is ultimate, clinging to it obscures wisdom. Chan master Jing similarly taught that conditioned methods shouldn't be entirely discarded, or realization becomes unattainable. These parallel teachings from Daoist and Buddhist masters could mutually verify each other, but were unfortunately concealed by human bias.

The conclusion clarifies: Daoist attainment requires actual realization, but ultimately transcends all realized states. Just as immortals nurture the spiritual embryo to form the spirit (Shen), they must further refine spirit into emptiness—even after attaining the Dao, they don't cling to the concept of attainment.

This scripture primarily discusses how the cultivation of immortality (Xian) and Buddhist practice share the same fundamental principles. True attainment of the Dao is not about clinging to a state of "having attained something." If one constantly dwells on what they have gained, they become bound by such thoughts and fail to achieve genuine liberation. As the Wushang Neimi Zhenzang Jing (Supreme Inner Secret Treasury Scripture) states, the true Dao is the state of cessation (a transcendent realm of purity beyond birth and death), yet this cessation is not something to be deliberately pursued. Similarly, the Buddhist Yuanjue Jing (Perfect Enlightenment Sutra) teaches that true cessation follows natural spontaneity—there is no "cessation" to cling to. This demonstrates the essential unity between the paths of immortality and Buddhism.

Not only is this true for immortals and Buddhas, but even the Buddhist practitioners' teaching that "all dharmas return to One, and the One returns to Nothingness" shares this same principle. The immortal master Lü Dongbin (Lü Chunyang) taught that whether cultivating immortality or Buddhism, the key lies in "illuminating awareness" (the practice of clear, wakeful consciousness). One must maintain this illuminating awareness during seated meditation and stillness, as well as when entering the realms of emptiness and cessation. From beginning to end, the cultivation of immortals and Buddhas cannot be separated from this awakened awareness—this is true enlightenment. Without genuine illuminating awareness, mere verbal claims are false practice.

Some immortality seekers, upon hearing Lü Dongbin's teaching on the unity of immortals and Buddhas, fabricated stories claiming that Lü once sought instruction from Chan Master Huanglong. Historical research, however, shows that Chan Master Huanglong (Huitang) lived during the Song Dynasty and was a neighbor and close friend of the literary figure Huang Tingjian, while Lü Dongbin lived during the Tang Dynasty's Zhenyuan era and attained ascension as early as the Kaicheng era. The two could never have met—this is purely a slanderous rumor against the Daoist path. Historical records confirm that Lü Dongbin passed the imperial examination at age 42 and served as magistrate of Dehua County. At Mount Lu, he met Zhongli Quan (one of the Eight Immortals), resigned from office to follow him in cultivation, attained the Dao after seven or eight years, and ascended as an immortal at age 64 from Yellow Crane Tower. How could an immortal who had already achieved the Yang Spirit (a supreme attainment in Daoist practice) and transcended life and death for over five centuries possibly seek guidance from a later Buddhist monk? This illustrates that while immortals and Buddhas share the same principles, they each have their own lineages and need not disparage one another.

This passage primarily discusses the relationship between immortal cultivation and the cycle of birth and death. It mentions that some Buddhist monks, even after five hundred years of practice, still fail to attain the state of "Great Stability" (a profound meditative state) and ultimately cannot escape the wheel of reincarnation. This is because they have only mastered the "method of death" (referring to mere seated meditation without understanding the dual cultivation of nature and life [xingming shuangxiu]).

The author cites Lü Dongbin (Master Lü) as an example, illustrating that those who have truly attained the Dao can freely enter and exit meditative states, transcend the cycle of birth and death, and repeatedly manifest their sacred presence to deliver beings. In contrast, monks like Huanglong Chan Master, who never reappeared with spiritual powers after death, demonstrate that they have fallen back into reincarnation. The phrase "ultimately ending in emptiness" spoken by Maitreya Buddha refers precisely to this kind of cultivation that fails to grasp the essential method.

The author argues that the paths of immortals and Buddhas are fundamentally one and criticizes practitioners who arbitrarily separate the two traditions and engage in disputes, as this only leads them astray. He traces the lineage of Daoism's Northern and Southern Schools: from Laozi (Taishang Laojun) transmitting to Zhongli Quan, who then passed the teachings to Lü Dongbin (Chunyang) and Liu Cao (Haichan). These later divided into the Northern and Southern Schools. The Northern School is represented by Wang Chongyang and the Seven Masters of Quanzhen (including Qiu Chuji), while the Southern School is represented by Zhang Boduan (Ziyang) and the Five Patriarchs of the Southern School. All these patriarchs transmitted cultivation methods that unified the paths of immortals and Buddhas.

Finally, the text emphasizes grasping the root of cultivation, particularly pointing out that refining True Essence (primordial Qi [qi]) is the crucial gateway. Only by encountering a true immortal who imparts the method to discern the "True Medicine" (referring to the Primordial One Qi [xian tian yi qi]) can one achieve genuine success in cultivation. Otherwise, the methods circulating in the mundane world will ultimately prove ineffective. The author reminds later practitioners to cultivate earnestly, as only through self-realization and dedicated practice can one attain true accomplishment and preserve the precious gift of human existence.

In the Daoist cultivation system, all classics that discuss alchemical methods repeatedly emphasize one core principle—this is merely the foundational practice at the initial stage. The first phase of cultivation is called the "Hundred Days Barrier," where practitioners must transform their vital essence (Jing) into abundant Qi through the method of "refining essence into Qi (Lianjing Huaqi)." When cultivators achieve a state of abundant essence and Qi, akin to that of a child, they attain the preliminary accomplishment of immortality, known as "minor attainment" (the elementary stage in Zhongli Quan's three-stage cultivation theory).

Without mastering this foundation, one cannot obtain genuine essence and Qi, let alone achieve the great Dao. True realization of the Dao requires progressing through more advanced stages: during the "Ten Months of Gestation" phase, the original spirit (Yuanshen) is nurtured to maturity, ultimately attaining the status of a "middle-level immortal"; then, through the "Nine Years of Facing the Wall" cultivation in emptiness, one may become a "celestial immortal of the highest purity," completing the highest level of "great attainment."

Some mistakenly believe cultivation stops at the initial stage, thus belittling the "minor attainment" realm without realizing there are far grander stages beyond. Buddhists have borrowed the Daoist concept of "minor attainment" to disparage Daoist cultivation, unaware that Buddhist practice follows similar stages. The Buddha explicitly states in the Śūraṅgama Sūtra: attempting to cultivate meditation without abstaining from sexual desire is like trying to cook sand into rice—even after a hundred years, one would only end up with hot sand, for sand is fundamentally not the material for making rice.

This analogy reveals the essential principle that cultivation requires abstaining from sexual desire. Just as rice is needed to cook a meal, cultivation demands a foundation of purified body and mind. What Buddhism calls the "Vajrāsana" (Diamond Throne) corresponds to the pure Yang energy achieved through Daoist "refining essence into Qi"—both serve as the foundation for spiritual cultivation. The Buddha used this foundation to practice meditation and realize Nirvāṇa, ultimately attaining Buddhahood; Daoism, through ten months of concentrated spirit and meditative stillness, achieves the Yang spirit. Both follow the same fundamental principle, akin to using rice to cook a meal.

Claiming to cultivate without abstaining from sexual desire is like trying to cook with sand—genuine attainment is impossible. Sexual desire depletes the root of life, rapidly corrupting body and mind, making it impossible to abide in one's true nature or realize Nirvāṇa. These teachings of the Buddha are absolute and unchanging truths. Notably, Buddhism's "renunciation of desire" belongs to the Hīnayāna teachings, while "meditation" pertains to the Mahāyāna and other advanced vehicles. Yet later generations abandoned these foundational practices of renunciation and meditation, proclaiming themselves "instantly awakened Buddhas." This is not only as absurd as cooking sand but even more outrageous than trying to cook without water—it amounts to slandering the Dharma itself.

Without firewood and rice yet speaking of cooking a meal—I must admonish the wise to carefully consider this principle.

You use bodies steeped in lust to seek the wondrous fruit of Buddhahood. Even if you attain some mystical insights, these still stem from the root of desire. Thus, cycling through the three wretched paths of beasts, hungry ghosts, and hell-beings, you will certainly find no liberation. If one wishes to realize the nirvana of the Tathāgata (Buddha), by what path should one cultivate?

Severing desire is the fundamental path of the Tathāgata’s initial cultivation. The so-called "lustful body" refers to the bodies of ordinary beings drowning in sensual craving. As long as the body still leaks desire (referring to the loss of Jing and Qi), one cannot achieve the "exhaustion of outflows" (one of the six supernatural powers, referring to the state of complete severance of afflictions). Only by attaining the exhaustion of outflows can one reach the true state of no leakage, where Jing and Qi are complete and abundant, enabling one to attain longevity. If the exhaustion of outflows is not achieved, and Jing and Qi continue to leak, one will inevitably exhaust one’s essence and deplete one’s Qi, leading to death and subsequent sinking into the three wretched paths to endure the suffering of samsara. All this stems from not following the Tathāgata’s teaching of severing desire as the path of cultivation.

If the root of desire is not thoroughly severed, lustful acts will gradually multiply. Even if one occasionally awakens to Buddha-nature and attains some insight, ultimately the habit-energy of desire will dominate, and the meager mystical insights mixed within will hardly bear true fruit. Know that the Sixth Patriarch Huineng said, "The nature of desire is precisely the nature of purity," meaning that only by severing desire can one reveal the pure nature. How can later generations fail to first sever desire yet deceive others by claiming to meditate and awaken to the Dao?

One must completely sever the mechanisms of body and mind that give rise to desire, without even clinging to the notion of "severing." The so-called "mechanisms of desire in body and mind" mean physically abstaining from lustful acts and mentally extinguishing lustful thoughts—this is called severing both body and mind. At first, one must forcibly restrain oneself, but later, one can truly realize the state of severance.

In the stage of forced severance, it is like the six heavens of the desire realm (the six celestial realms in Buddhism), where consorts still exist, but practitioners firmly uphold the precept against lustful conduct, gradually severing the bodily mechanisms of desire through pure cultivation. Upon reaching this stage, the body will naturally no longer give rise to desire, like the "concealed male organ" among the Buddha’s thirty-two marks (where the genitals are hidden like a horse’s) or the "rejuvenated" childlike body spoken of in Daoism—this is the true realization of physical severance. Only at this level can one truly transcend the desire realm.

Ascending further into the form realm (a higher celestial realm), though traces of desire may not yet be entirely extinguished, since great practitioners have resolved to transcend the world, why would residual thoughts remain? This is because while awake, they may maintain correct awareness free of distractions, but in the dullness of sleep, they may be disturbed by sleep demons or temptations of feminine allure. Those with insufficient meditative power may sink along with these thoughts.

The obstacles to cultivating Dao power during practice stem entirely from the failure to completely eliminate distracting thoughts. If practitioners can develop steadfast concentration (focusing power), they can subdue these wandering thoughts, returning the mind to the correct path of awakening and thoroughly severing demonic obstructions and deviant notions. This describes the initial stage of entering meditative absorption (chan ding), where one forcibly cuts off distracting thoughts. One must persist until every thought is severed, reaching a state where no distracting thoughts remain to be cut—only then can it be called the natural and genuine realm of thought-severing.

This state can only be attained through the meditative skill of "thought-stilling" (nian zhu, where thoughts come to rest). As the Sixth Patriarch Huineng said, "The meditative mind is without thought." Only when one truly realizes the complete severance of the root of lustful desires can this be considered the innate threefold training of precepts, concentration, and wisdom. From here, one enters the great state of absorption (da ding), maintaining constant concentration until even the notion of "severing thoughts" itself dissolves. Only then can one aspire to realize the fruit of Buddhahood.

For practitioners to use body and mind to sever the root of lustful desires is the correct initial resolve for cultivating the path of immortals and Buddhas. For the body to cease lustful actions and the mind to become still is the correct result of realizing the state of immortals and Buddhas. Only by practicing according to this method can one hope to attain Buddhahood. Those who do not practice this way yet foolishly claim they will become Buddhas are like those seeking fire from the ocean or ice from a furnace—utterly absurd. These are nothing but the deceptive teachings of heretics who borrow Buddhist terminology to mislead people. They should be shown this passage from the Śūraṅgama Sūtra to awaken their deluded minds.

Understand that lust is fundamentally not the root of the Buddhist path. One must sever lust and preserve vital essence (jing qi)—this is the true foundation of pure spiritual practice (brahmacarya). It is also said that those who practice meditation without uprooting lust will inevitably fall into the demonic path. What is called meditation is precisely the settling of the mind in meditative stillness. The World-Honored One (the Buddha) cultivated austerities for six years in the Himalayas, attaining the four dhyānas and eight samādhis before realizing the path to Buddhahood. Here, the "demonic path" refers to lustful matters—the demon king once tempted the Buddha with demon maidens, but because the Buddha had already severed the root of lust, he remained unmoved. Ordinary people in the world, deluded by beauty, follow lust and thus fall into the demonic path—this is not the Buddhist path. Know that demons and Buddhas are diametrically opposed.

It is also said that if the mind remains untainted by lust, one will not follow the cycle of birth and death. Practitioners who have not yet attained the first dhyāna in the form realm (material world), whose minds are not yet settled, may suddenly give rise to lustful thoughts and attachments during absorption, causing them to fall into rebirth. Some ancient meditators clearly entered absorption yet still took rebirth—all due to this reason. Or when beings in the desire realm reach life's end, at the transition between this life and the next, if their breathing ceases but lustful thoughts remain unsevered, even seeing others engage in lust can arouse such thoughts, leading them to follow these lustful thoughts and actions into rebirth.

This scripture primarily explores the relationship between lustful desires and the cycle of birth and death (samsara), as well as how practitioners can transcend this cycle by abstaining from sexual desire.

When a deceased person enters a mother's womb for rebirth, if lustful thoughts remain unbroken, they will continue trapped in the cycle of reincarnation. The key lies in eradicating sexual desire from the heart—reaching a state where one sees beauty without arousal, or even perceives attractive forms as if they weren't there. Achieving this means no longer being reborn after death, attaining the status of a celestial being. Advanced practitioners may achieve arhatship, becoming like the Buddha who preached Dharma for eight thousand kalpas and entered meditation for eighty-four thousand kalpas to attain immortal life.

The Buddha once said he was most reluctant to admit women into the monastic order, because even if they didn't actively disrupt practice, they might arouse lust in others—precisely the crux of samsara. Therefore, the moment a practitioner entertains lustful thoughts marks the beginning of their reincarnation cycle. This is why Buddhist precepts strictly forbid novice monks (shramanas) from keeping young attendants—to sever the root of sexual desire.

Quanzhen (Complete Perfection) patriarch Ma Danyang similarly warned disciples: True cultivation doesn't require young attendants; one or two mature assistants in their forties or fifties suffice to maintain pure practice.

Lust originates from consciousness arising through the six senses (eyes, ears, nose, tongue, body, and mind)—these defiled thoughts represent the dust clinging to sensory perception. Indulgence without renunciation means flowing with worldly dust while turning away from enlightenment, hence the saying "without eliminating lust, one cannot transcend the dusty world."

Someone might ask: "Though I've heard many sublime Buddhist teachings, how exactly does one abstain from lust to transcend demonic paths?" The answer: This teaching addresses ordinary people and false scholars—true sages naturally maintain strict precepts and pure practice. Having resolved to study Buddhism, how could we violate the Tathagata's most important prohibition?

The text cites the example of Venerable Kātyāyana: Through meditation practice in the Himalayas, he attained the four dhyanas and five supernatural powers (abhijñā), becoming leader of eight hundred flying immortals. This demonstrates how meditation can lead to supreme spiritual attainment.

This passage discusses the six supernatural powers attained through cultivation: divine hearing (ability to hear distant sounds), divine vision (ability to see distant things), miraculous mobility (ability to transform freely), mind-reading (ability to know others' thoughts), and knowledge of past lives (understanding karmic causes from previous existences). However, to achieve true liberation, one must practice Buddhist teachings and cultivate purity to attain the sixth power—"cessation of defilements" (extinguishing all afflictions). Only through abstaining from sexual desire can one transcend demonic paths, rise above the world of desires, and break free from the cycle of birth and death.

Maintaining purity in conduct generates the power of precepts, which in turn gives rise to the power of meditation and wisdom. Thus, among the five basic Buddhist precepts, the foremost is abstaining from sexual desire. Without sexual desire, there are no worldly attachments, no demonic obstructions, and one can transcend the realm of desires and the cycle of rebirth. Therefore, all cultivation methods must prioritize abstaining from sexual desire.

Nowadays, some claim to practice Buddhism without truly understanding its teachings, dismissing the importance of abstaining from sexual desire as emphasized in the scriptures. In truth, the scriptures do not neglect this point—they simply address it concisely. These individuals slander Buddhism, thinking abstaining from sexual desire is not essential to cultivation. Because the scriptures only mention the term "abstaining from sexual desire" without elaborating on specific methods, they mistakenly assume it is unimportant. If it were truly unimportant, why would the Buddha repeatedly emphasize it as the foundation of practice? For example, the Śūraṅgama Sūtra repeatedly stresses the importance of abstaining from sexual desire, though it does not detail the method as explicitly as Daoism's "refining Jing into Qi" (transforming vital essence into higher energy).

Monastics who fail to grasp this principle and cannot practice it claim the Buddha did not value this method. How lamentable! It is precisely because they overlook this foundation that Buddhist cultivation struggles to attain fruition. Cultivating the six supernatural powers leads to Buddhahood, but without faith in and acceptance of abstaining from sexual desire, one cannot achieve these powers and thus cannot attain Buddhahood. So, by what path can one realize the nirvana of the Tathāgata?

Daoist cultivation similarly addresses the ultimate state concisely. This is not because Daoism refuses to elaborate but because a single phrase can encapsulate the entirety. Thus, it is said, "Half a word can penetrate the profound." When one reaches the stage of "refining Shen to return to emptiness" (returning spirit to the void) and unites with the Dao, one attains absolute nothingness. The ultimate nothingness has no form; the ultimate emptiness cannot be described—what need is there for excessive words?

The Wuji (Ultimate Non-Being) is the state of absolute nothingness, beyond verbal expression. Originally, nothing need be said, but to guide later practitioners, four lines are reluctantly offered: "Only emptiness is seen; the emptiness itself is empty; even 'emptiness' is empty; serene and eternally still." These lines come from the Scripture of Purity and Tranquility, meaning: one perceives only emptiness; the emptiness perceived is itself nonexistent; even the concept of "emptiness" vanishes; ultimately, one abides in eternal stillness.

Later generations who fail to comprehend the true essence of cultivation remain utterly ignorant of how the state of "enlightenment through a single word" is fundamentally no different from Buddhism's Nirvana (the liberation from the cycle of birth and death). Like cold ashes devoid of even a spark, they completely miss the truth proclaimed by the Celestial Worthy of Primordial Beginning (Tianshi, the supreme deity of Daoism) in the Supreme Secret Treasury Scripture: genuine extinction transcends even the very concept of "extinction."

Some, finding Daoist scriptures comparatively terse, slander Daoism as inferior to Buddhism's Nirvana. Yet the Secret Treasury Scripture long ago clarified: when the mind attains stillness, it becomes wondrous cause; when consciousness remains utterly unmoved, it becomes wondrous fruit. These critics equally fail to understand that Buddhism's detailed discourses on Nirvana ultimately describe a meditative state where breath neither enters nor exits, and thoughts neither arise nor cease. The Secret Treasury Scripture states that "neither birth nor extinction, neither cause nor fruit" constitutes true attainment—perfectly aligning with the immortal scriptures' teaching of "neither existence nor non-existence, eternally quiescent." Countless words expounding the mind's original nature ultimately distill to the latter half of the alchemical process: "refining self and spirit, returning to emptiness and entering stillness."

Buddhism and Daoism differ in terminology but converge in principle. Yet during Buddhism's degenerate age, some stubbornly emphasize distinctions like a dwarf carrying a plank—seeing only one side. Pitifully, certain Buddhists compete in self-aggrandizement, unaware that the Buddha's greatness precisely intersects with the Daoist path. Both transcend cosmic cycles (kalpas), existing before heaven and earth—that solitary spiritual radiance shines independently, unchanged by cosmic creation or dissolution. This is true "greatness."

Meanwhile, some cultivators dismiss Buddhism as illusory emptiness, ignorant that Daoism and Buddhism share the same essence of "true emptiness" (absolute reality beyond being and non-being). What is genuine "emptiness"? It is Buddhism's "empty yet not empty, not empty yet empty": when the mind is quiescent yet maintains right awareness, this is "emptiness containing non-emptiness." Mere stillness without awareness sinks into inert emptiness. Similarly, while abiding in meditation appears "non-empty," higher wisdom lies in not clinging to meditative states—remaining unattached like open sky. This is "non-emptiness containing emptiness." Clinging to meditative forms binds one to lesser vehicles, far from true Buddhahood.

Alas, scholars of both schools—claiming to study immortality yet missing Daoism's essence—how could they comprehend Buddhism? Their self-proclaimed Buddhist learning amounts to empty reputation.

When Buddhist practitioners criticize the Daoist cultivation system without understanding it, this reflects the folly of scholars in the Dharma-Ending Age (the Buddhist concept of spiritual decline). If they didn't exalt themselves while disparaging others, how could they prevail in competing for followers and resources?

In truth, the fundamental cultivation paths of Buddhism and Daoism share the same essence, differing only in terminology. Both emphasize: first severing sexual desire to transcend the Realm of Desire (one of the Three Realms), then using meditative practice to transcend the Realm of Form (material world), ultimately attaining the Four Formless Absorptions to transcend the Formless Realm. This is their shared foundational principle—the differences lie merely in expression.

Yet upon deeper examination, elaborate explanations don't necessarily indicate superiority, nor does conciseness imply inferiority. The term "bearing failure" in the Transmission of the Lamp (a Chan Buddhist text) originally referred to failing to reach ultimate realization in practice.

Today I lament for Buddhism but rejoice for the Daoist path. Many Buddhist practitioners lose their way from the outset while obstinately pursuing erroneous results. They verbally pledge to uphold the Brahmajala Sutra's precepts, yet their conduct remains thoroughly worldly, completely neglecting the initial diligent effort required in cultivation. Some mimic the Four Formless Absorptions without any foundation in actual practice—they reject the Buddha's gradual path through the Four Dhyanas and Eight Concentrations, presumptuously attempting to leap directly to the Nine Great Absorptions (highest meditative states) without traversing the Five Pure Abodes (highest heaven of the Form Realm) or the Four Formless Absorptions. These ordinary people claim sudden enlightenment without practice, indulging in empty talk while refusing earnest cultivation—this is true delusion.

Those who comprehend this truth and return to authentic practice, progressing step-by-step until complete realization and ultimate liberation, become true dragons and elephants of Buddhism (eminent practitioners). But if they resent my clarifying the truth on the Buddha's behalf and instead slander me, then the true Dharma will never flourish, and the correct methods of the Four Dhyanas and Nine Absorptions will remain unpracticed.

Those who abandon the dual cultivation of nature and life (xingming shuangxiu, a key Daoist theory) while idly discussing mind and nature may claim universal salvation, but actually lead beings astray. Without solid cultivation foundations, it's like expecting harvest without plowing—they'll ultimately starve.

This scripture discusses the common pitfalls in spiritual practice and the key to transcending the cycle of rebirth.

Some practitioners engage in empty theorizing, discussing Chan (Zen) principles without actual cultivation, even mistaking "all humans must die" as enlightenment and passively awaiting death. This completely contradicts Buddhism’s true aim of transcending life and death. Others may practice meditation but remain stuck at the stage of attaining supernatural powers (the four dhyanas and five psychic abilities), failing to reach the highest liberation of "cessation of outflows" (the sixth and supreme psychic power), which prevents them from overcoming death. This, too, violates Buddhism’s fundamental aspiration for agelessness, deathlessness, perpetual youth, and freedom from illness.

The text uses the metaphor of "rolling a mustard seed onto a needle’s point" to illustrate the difficulty of cultivation: just as it is nearly impossible for a mustard seed rolled from the peak of Mount Sumeru to land precisely on the tip of a needle below, so too is human life rare, turning one’s mind toward the Dao even rarer, and encountering the true Dharma rarer still. Even if one is fortunate enough to encounter Buddhist teachings, mastering the method to transcend life and death is as difficult as "rolling a mustard seed onto a needle’s point."

To escape the cycle of rebirth, one must eliminate internal and external distractions: externally, one must resist the temptations of the six dusts (form, sound, smell, taste, touch, and mental objects), and internally, one must pacify the delusions of the six sense faculties (eyes, ears, nose, tongue, body, and mind). Only then can cultivation align with the Buddhist path. The methods taught by Bodhidharma, such as the "Ten Faiths of Returning to Emptiness," and Śākyamuni’s practice of "self-selecting parents" are crucial for transcending the three lower realms (hell, hungry ghosts, and animals).

Finally, the text emphasizes that if one does not cultivate and awaken in this lifetime, liberation in future lives will be even harder to attain. As Maitreya Buddha said, even after eighty thousand kalpas of practice, without genuine cultivation, all efforts remain futile. One must practice diligently, allowing wisdom to blossom in the mind (symbolized by the golden lotus) and realizing the true meaning of the Dharma (turning the Dharma wheel), ultimately attaining the indestructible vajra state to truly transcend calamities. Those who only talk without practicing—the so-called "lip-service Chan"—will inevitably fall into the pitfall of "empty annihilation" (failed cultivation).

Those who cultivate the path of immortality often become complacent upon achieving minor initial accomplishments, failing to persevere to the ultimate goal. Some practitioners, having just entered the gate of practice and obtained modest results like prolonged lifespan, grow arrogant and cease striving for deeper realization.

The Inner Secrets of the True Treasury Scripture (Neimi Zhenzang Jing) states: "Those content with minor vehicle (xiaocheng) cultivation can never attain the Dao." Similarly, the Jade Clarity Scripture of Dao and Virtue (Yuqing Daode Jing) observes: "Some fail to comprehend the true nature of practice, never completing the six stages of cultivation (liucheng). With wisdom unopened, they ultimately regress."

The "complete process" mentioned here refers to the full attainment of divine immortality (shenxian), not yet the higher celestial immortality (tianxian) realm. During the ten-month meditation for refining the embryonic spirit (taishen, an advanced Neidan stage), practitioners often experience mental restlessness, unable to enter deep samadhi. While they may develop some internal spiritual powers, failure to unite spirit (shen) and qi in sublime emptiness prevents the awakening of wisdom and transcendence of life and death.

If cultivators cannot reach the supreme state of "great stability" (dading), with minds constantly fluctuating, they merely indulge in deluded thoughts. Though they may wish to display external spiritual powers, these remain unrealized. This constitutes what is called "failure to persevere to the end."

The highest cultivation (shangshang cheng) involves refining the primordial spirit (yuanshen) to merge with emptiness, becoming one with the Great Dao. Maintaining this ultimate state without regression while preserving the incorruptible form leads to deathless longevity, establishing an enduring foundation for Dao-realization.

The "solid ground" mentioned refers to the genuine attainment of immortal foundation—not illusory or insubstantial. With this foundation, one can continue cultivation to ultimately realize the supreme state, achieving parity with Buddhist practitioners. However, regarding discipline observance, Buddhists indeed perform better.

While Buddhism has its mediocrities, it consistently produces truly disciplined monks. Daoism, though possessing profound adepts, often sees them mingling with vulgar practitioners who disregard precepts. This constitutes Daoism's inferiority to Buddhism in this aspect. Buddhism preserves specialized vinaya scriptures, with "vinaya masters" (lüshi) dedicated to expounding precept essentials for public understanding and practice. When robed monks beg for alms, laypeople—regardless of authenticity—address them as "precept-keeping monks" and gladly offer donations. In contrast, while Daoism possesses numerous celestial codes and immortal precepts, few maintain them completely.

(Note: "Six stages" refers to six cultivation levels; "embryonic spirit" denotes the nurtured primordial spirit in Neidan practice; "vinaya masters" are Buddhist monks specializing in discipline studies)

This passage primarily examines the transmission of Daoist precepts while comparing the essential nature of Buddhist and Daoist cultivation practices. The original text conveys the following key points:

Many precept regulations found in Daoist scriptures are secretly guarded by temple abbots, kept from ordinary practitioners. Compounded by the lack of masters specializing in precept transmission, this has led to the misconception that Daoist immortals need not uphold precepts. Consequently, when Daoist priests go seeking alms (requesting donations), the absence of visible markers of precept-keeping (such as Buddhist monastic robes) means laypeople don't show them the same respect accorded to precept-holding monks. This drives many to choose Buddhist ordination for easier alms-seeking. A vivid Hangzhou proverb illustrates this: "Monks collecting alms are like cats catching mice—success every time; nuns like dogs catching mice—occasional success; but Daoist priests are like horses trying to catch mice—lucky to succeed once in a lifetime."

The author emphasizes that whether cultivating immortality or Buddhahood, practitioners are fundamentally the same. Our physical bodies all originate from parental Jing (essence) and Qi (vital energy), while our minds all possess that pure, unclouded innate nature. Buddhist practitioners should not abandon foundational cultivation methods—all Buddhas and bodhisattvas practiced according to the Dharma, as the ancient saying goes: "Lacking even one method, Buddhahood cannot be attained." Nor should they sever connection with the Daoist path due to discriminatory thinking, since human nature is ultimately one. The Avatamsaka Sutra states: "Protect all Buddhist teachings while embracing the Great Immortal's Dao"—even the Buddha simultaneously cultivated the Daoist path, so ordinary people should understand how Buddhist and Daoist cultivation share identical essence.

(Note: "Kalpic cycles" refers to cyclical cosmic destruction and renewal; "World-Honored One" is an honorific title for Śākyamuni Buddha; the Avatamsaka Sutra is a foundational Mahayana Buddhist scripture)

This scripture primarily discusses the fundamental unity between the Daoist immortal path and Buddhist Dharma, emphasizing that practitioners should not become attached to superficial differences in form.

The text points out that whether it's the Daoist emphasis on precepts, forbearance, diligence, meditation, and wisdom, or the Buddhist advocacy of expedient means, compassion, and pure vows, these methods are essentially interconnected. When encountering Daoist methods, one practices the immortal path; when encountering Buddhist teachings, one cultivates the Dharma—both ultimately seek transcendence. Immortals and Buddhas are fundamentally one, merely manifesting differently in appearance—Daoists retain hair and beard while monks shave their heads, yet these are only surface distinctions, as the inner truth of cultivation remains identical.

The crux of practice lies in genuine cultivation and actual realization. Though the paths of Daoist and Buddhist practice are expressed differently, both combine "methods of action" (youwei) and "non-action" (wuwei). In Daoism, "action" refers to concrete cultivation techniques like the Lesser Celestial Circuit (refining essence into qi) and Greater Celestial Circuit (refining qi into spirit), while "non-action" denotes attaining a state of tranquil qi and awakened spirit, merging with the Dao. In Buddhism, "action" involves expounding scriptures and liberating sentient beings, while "non-action" means deepening meditation to realize emptiness.

The author specifically cautions practitioners: avoid clinging to sectarian views, neither fixating solely on Daoist methods of action nor exclusively on Buddhist non-action. True cultivation requires both—concrete practice methods alongside awakened realization. Partiality leads either to sterile emptiness (hollow theory) or superficial formality (shallow practice), neither yielding genuine realization.

Finally, it emphasizes that practitioners should aim for the "right awakening" of sudden enlightenment to original nature. Whether choosing the immortal path or Buddhist Dharma, one must diligently persevere. The depth of realization depends entirely on the practitioner's diligence and sincerity, not on distinctions between schools.

This passage explores the fundamental unity between the Immortal Path (Xiandao) and Buddhist Dharma, emphasizing the importance of avoiding extremes in spiritual practice.

Regarding cultivation methods, Chan masters teach that "conditioned methods" (youwei fa, active cultivation) serve as the path to unify all dharmas, while "unconditioned methods" (wuwei fa, natural spontaneity) represent the ultimate return to the source. The eminent monk Sengzhao from the Western Regions cautioned that complete abandonment of active practice makes Buddhist realization impossible, yet obsessive attachment to wuwei obscures wisdom. Authentic cultivation requires upholding precepts to develop concentration and insight—progressing through youwei practice to ultimately realize wuwei. Without this balance, practitioners risk falling into nihilistic emptiness.

Concerning the identity of Śakra Devānām Indra (the Buddhist guardian deity), scriptures record he was originally the ruler of Trāyastriṃśa Heaven (the second desire-realm heaven) who, after exhausting his celestial merits, incarnated as a human. Through encountering Śākyamuni Buddha's teachings, he attained realization. Notably, the Buddha himself referred to himself as the "Seventh Immortal" or "Indra," demonstrating the inherent unity of Immortal Dao and Buddhist Dharma. Thus, we should neither oppose these paths nor claim that immortality cultivation requires no Chan practice.

Those with great wisdom comprehend this common origin, yet later generations often fail to accept this truth due to shallow foundations, insufficient merit, or distorted views. The text laments how contemporary Daoist deviations have abandoned genuine Xiandao practice—obsessing over therapeutic massage techniques, sexual alchemy, or profit-seeking through elixir consumption. Such reckless conduct utterly betrays cultivation's true purpose.

The author concludes sorrowfully: observing both traditions today, few truly grasp this profound unity—a consequence of sentient beings' diminished merit and deep karmic obstructions. This passage seeks to dismantle prejudices dividing Immortals and Buddhas, calling for a return to orthodox cultivation.

This passage from The Combined Discourse of Immortals and Buddhas delivers a stern critique of the prevalent social phenomena where people exploited the name of spiritual cultivation to engage in licentious and deviant practices. The Celestial Worthy of Primordial Beginning (the supreme deity in Daoism) points out that many have strayed into heretical paths, indulging in so-called "battle techniques of harvesting" (a false method claiming to cultivate through sexual intercourse), which in reality corrupts the true Daoist practice. These individuals, driven by hedonism and burdened with heavy sins, suffer numerous hardships in life and, after death, will fall into hell to endure eternal torment.

The scripture emphasizes that those truly aspiring to become immortals must have cultivated the right path in their past lives. They would never resort to unorthodox methods, much less deceive and harm others, but instead devote themselves sincerely to cultivating virtue (De). Sadly, in this turbid mundane world, the authentic path of immortality has long been obscured. What people encounter are mostly licentious techniques masquerading as cultivation, leading many astray. These individuals exhaust their vital essence (Jing) and spirit (Shen), lose their lives, and still refuse to repent.

Master Qiu Chuji (a patriarch of the Quanzhen tradition) clarifies that true adepts attain realization through "pointing and awakening in emptiness" (direct celestial initiation). The key to cultivation lies in the internal refinement of spiritual Qi (primordial energy) and the external alchemical transformation of mercury (Golden Elixir practice), along with the secret oral transmissions. Yet some ignorant mortals dare to deceive the world without understanding either internal or external cultivation, causing immense harm.

The text also criticizes the degeneration within certain Buddhist circles: some neglect genuine Buddhist teachings, instead using scriptures as tools for profit. Outwardly, they advocate merit-making while secretly enriching themselves. Under the guise of protecting the Dharma, they resort to violence, mistaking victory in fights as "transcending sectarian boundaries" (a distorted notion of spiritual supremacy).

Finally, invoking the warnings of Master Chen (possibly Chen Tuan) and The Supreme Secret Treasury of Inner Truth Scripture, the passage cautions that even eloquent rhetoric can become an accomplice to demonic influence. The actions of ordinary heretics are all illusory, bearing no relation to the Buddhist teachings of non-arising, non-ceasing, and nirvana. These critiques directly address the religious chaos of the time, stressing that authentic practice must reject deceptive and deviant methods, grounding itself in virtuous conduct (De) and genuine realization of the Dao.

This passage critiques two erroneous tendencies in spiritual practice. The first refers to those who put on pretentious airs and seek novelty for its own sake, failing to pursue genuine Dharma (Buddhist teachings) while paradoxically taking pride in not learning from the Buddhas. Such individuals are in fact offenders against Shakyamuni Buddha and the thirty-three patriarchs of Zen, acting as demons who lead devout men and women astray into the cycle of rebirth.

Quoting the Buddha's warning from the Śūraṅgama Sūtra: "If one does not sever lustful desires, one will inevitably fall into the path of demons." These demonic multitudes falsely claim to have attained supreme enlightenment. The Buddha prophesied that after his parinirvana (final passing), many such demonic beings would arise—outwardly posing as virtuous teachers (good spiritual friends), yet secretly indulging in greed and lust, trapping sentient beings in the deep pit of emotional attachment and causing them to lose the true path of bodhisattva practice.

These practitioners harm both others and themselves while competing to pose as Dharma experts. How is this any different from selling counterfeit medicine with authentic prescriptions? They contribute less to society than those who simply encourage virtuous conduct. Alas, those who aspire to cultivate immortality or study Buddhism must guard against falling into these two heterodox paths (erroneous practices), for only then can there be hope for spiritual progress. Otherwise, allowing such delusions to take root in the mind—when will one ever realize the need to eradicate these false thoughts, truly cultivate one's inherent nature, and manifest the yang-spirit (the advanced life-form achieved through cultivation) to return to the void?
