《陰符玄解》

Preface to The Profound Interpretation of the Hidden Talisman – A Vernacular Explanation:

During the Bingzi year while studying ritual practices in Qingxi Mountain, I consulted Master Songshan about this classic: "Tradition attributes this text to the Yellow Emperor, though some claim it originates from the Spring and Autumn period, while Zhu Xi believed it was composed by a Daoist adept of the Warring States era. Some regard it as a manual for nurturing life, others as a treatise on statecraft and military strategy—which interpretation holds truth?" The master replied: "This is a scripture transcending worldly concerns, stemming from the Yellow Emperor's lineage at Mount Kongtong (the sacred site where he received teachings from Guangchengzi). It stands as the source of all classics across Confucianism, Buddhism, Daoism, and the Hundred Schools. It reveals the ultimate truth of life's origin, elucidates the mysteries preceding and following human birth, and contains exquisite methods for harnessing the creative forces of heaven and earth. Though concise in wording, it encompasses all phenomena; profound in principle yet simple in practice."

The master continued: "Its opening passages teach discernment of natural patterns, then mastery of temporal transformations, consistently emphasizing vigilance against subtle dangers. The core practice lies in stillness through Wuwei (non-action), using celestial movements as the standard. With the resolve to 'bite through an iron bun' (metaphor for unwavering dedication), one may penetrate the mystery of 'emerging from nothingness into being, and returning from being to nothingness.' Cultivated to the stage of spiritual transformation, even emptiness may be shattered. Claims about its composition during the Spring and Autumn or Warring States periods lack foundation, while interpretations as health cultivation or military tactics all miss its essence."

This classic was transmitted to me by Master Erwu (his Daoist name), and now I pass it to you. Through study, I discovered that though comprising merely 447 characters, it illuminates the fundamental principles of cosmic operation and Yin-Yang transformations, resonating with the Book of Changes. Buddhist teachings on "neither emptiness nor form," Daoist concepts of "neither being nor non-being," and Confucian theories of "Wuji and Taiji (Supreme Ultimate)" all find convergence here. Yet its peculiar phrasing and unconventional terminology often led commentators to subjective misinterpretations, obscuring its true meaning.

This spring, my nephew Baoxiang brought from Sichuan The Secret Revelation of the Hidden Talisman by Zhang Qingye, the self-cultivated Daoist of Ziyang Cave. Reading it, I found his commentary perfectly aligned with my own realizations, striking my desk in delight. This master of Nangong School techniques (a Daoist tradition emphasizing Fulu talismans) ultimately attained the Dao through Neidan (internal alchemy) practice. That his work reached me fulfills the ancient saying: "When a nobleman speaks truth within his chamber, its echo carries a thousand miles"—though my nephew's assistance certainly helped this auspicious encounter.

Interpretation of the Hidden Talisman Scripture

This precious Daoist scripture was left to me by a cultivator who has since attained immortality (through liberation from the corpse). It is deeply regrettable that I could not consult him in person. While the hidden cultivation secrets within have been partially revealed, I will elucidate their deeper meanings to make the text fully coherent. The applications of the "Five Thieves and Three Robbers," the mysteries of the "Killing Mechanism and Marvelous Vessel"—these can only be truly grasped through personal practice. I have distilled their essence into this commentary, titled Profound Interpretation. Readers must possess the wisdom to see beyond the words to truly comprehend its teachings.

My reason for disclosing these secret transmissions is not fear of criticism, but concern that those who misunderstand the true principles might dismiss them as absurd, thereby defiling the great path to immortality. May readers bear this in mind.

[Annotation on the Hidden Talisman Scripture]

"Hidden" (Yin) refers to the moon (Great Yin), while "Talisman" (Fu) denotes the twelve monthly cycles of conjunction and opposition between the moon and sun (Great Yang). This moment of celestial alignment is called the "Talisman's Sign." The moon itself does not emit light but reflects the sun's radiance—yet within it lies the True Fire (Primordial Qi), hence it is also called the "Fire Talisman." "Scripture" (Jing) refers to the moon's precise, tide-like movements. Previous interpretations of "Hidden" as darkness or the passage of time are mistaken. In truth, it explicitly describes how the moon (Great Yin) contains the sun's True Fire. Cultivating according to this principle—"stealing" the Qi of Heaven and Earth—is the profound method of Daoist practice. These three characters hold the scripture's entire secret.

[Interpretation of the Upper Chapter]

Observing the operations of Heaven's Dao and grasping the laws of nature form the foundation of cultivation. The character for "Dao" (道) originally meant "to walk downward" (comprising "head" 首 and "walking" 辶), yet the key to cultivation lies in the human body acting like the sun, embodying pure Yang. However, pure Yang cannot be achieved alone—it requires the cooperation of two. The character "two" (二) represents Yin, and through the union of Yin and Yang (two people)...

This scripture elucidates the profound meaning of the character "观" (observation/contemplation) in Daoist practice and the application methods of the "Five Thieves" (referring to the five senses of eyes, ears, nose, tongue, and body).

The structure of the character "观" conceals esoteric wisdom—the two "口" radicals at the top symbolize the dual qi of Yin and Yang, while the "见" component below represents the practitioner using their eyes to observe the patterns of celestial and terrestrial movements. The opening and closing of Yin-Yang manifests as naturally as the luminous interplay in the heavens. Practitioners must emulate the Dao's counter-rotating movement, maintaining the Middle Way while relying on the "one pill" (referring to the genuine qi in the Dantian) as the pivot of creation. Through cultivation following this principle, one may comprehend the mysteries of the "Yin Talisman" (the cosmic covenant that secretly aligns with heavenly mechanisms).

The scripture introduces the concept of "Five Thieves in Heaven": when the five senses become deluded by external phenomena, they transform into "Five Burdens," yet when recognized and mastered, they become tools for cultivation. The key lies in letting these thieves disturb others (external conditions) rather than allowing them to disturb oneself. Like straw dogs used in rituals, one must hold Yin-Yang in one's grasp—directing the Five Thieves to unsettle others while remaining adaptable oneself. Thus, myriad transformations will manifest within.

Human nature inherently contains the mechanism of the Five Thieves, which manifests within the human heart. Those who understand this principle pacify cunning intentions internally while employing this mechanism externally to establish their cultivation foundation. This foundation cannot be separated from primordial qi (the "six-one lead"). By harmonizing heart-nature with celestial nature, and aligning the Dao of Heaven with the Dao of Humanity, one attains a state beyond distance or doubt.

Finally, the scripture describes how the Three Powers (Heaven, Earth, and Humanity) activate their killing mechanisms: celestial killing manifests as shifting constellations, terrestrial killing as leaping dragons and snakes, while human killing shakes heaven and earth. When the killing mechanisms of all Three Powers activate simultaneously, it marks the moment when all things reestablish their foundations. The descending yang qi of stellar radiance represents Heaven's activation, while the ascending yin qi of leaping creatures represents Earth's activation. Described separately, they show distinct manifestations; described together, they form the complete cycle of terrestrial qi ascending and celestial qi descending.

The Xuanjie of the Yin Fu Jing (Secret Talisman Scripture) elucidates the profound interaction between heaven and humanity and the mysteries of cultivation, centering on comprehending the cyclical patterns of Yin and Yang energies.

When the Qi of heaven and earth intermingle, celestial radiance manifests, and as terrestrial Qi ascends, humans can perceive the unity of heaven and earth. This mechanism of resonance enables the reversal and circulation of Yin and Yang, with the key lying in the practitioner’s ability to merge with the cosmos. When a cultivator attains this state of oneness, they may access the purest "Qi of True Oneness" (Zhen Yi Zhi Qi) within the universe, mastering the profound workings of Yin and Yang transformation. Such a state transcends ordinary growth and change, returning to the primordial mystery of Qian Yuan (the cosmic origin).

The scripture particularly emphasizes the concept of "Heaven and Humanity Acting in Unison" (Tian Ren He Fa), which constitutes the core secret of the entire text. Human nature varies in intelligence and dullness, but the key lies in restraining the disturbances of the nine orifices (eyes, ears, nose, tongue, body, etc.), with special emphasis on controlling the three most critical senses: the eyes, ears, and mouth. The genuine "Qi of True Oneness" arises from subtlety and requires specific cultivation methods to obtain. This skill is entirely governed by the mind—if one is led astray by habitual tendencies, apparent cleverness may lead to failure; but if one transcends these tendencies, seeming dullness conceals great wisdom.

In practice, cultivators should adopt a method that appears "clumsy yet profoundly skillful": extracting True Yang from within Yin, deeply storing it within the body, and allowing the genuine Qi to circulate unhindered along the Conception (Ren) and Governing (Du) meridians. Only then can vitality be preserved long-term. Ordinary people, unaware of this mystery of storing Qi and failing to restrain the reckless movements of the nine orifices, inevitably lose their life force.

The text employs the metaphor "fire is born from wood": just as wood generates fire only to be consumed by it, if humans fail to uphold discipline and tranquility, they will be driven by deluded thoughts and lose their innate authenticity. The later reference to "three women conspiring" is a metaphor for the eyes, ears, and mouth—if these senses act recklessly, they will disrupt the state of heaven-human unity at critical moments in cultivation. Only those who understand this principle and refine it through practice can attain sagehood.

This passage primarily teaches that cultivation requires restraining the senses, maintaining balance between movement and stillness, and employing seemingly simple methods to achieve true wisdom—ultimately realizing the state of unity between heaven and humanity.

This passage elucidates the principles of Yin-Yang interaction and the transformation of Jing (essence) and Qi (vital energy) in Daoist cultivation. Let me explain it section by section:

The profound meaning of the character "Sheng" (圣):

This character secretly encodes the essential technique of uniting Kan (Water) and Li (Fire) in cultivation. When kidney water (Kan) and heart fire (Li) interact, one attains the primordial True One Qi, which returns to the Central Palace (Yellow Court in the middle Dantian). This constitutes the true royal path of cultivation. Never underestimate the profound meaning contained within this single character.

The mystery of celestial birth and celestial slaying:

"Celestial birth" refers to following the natural forward course of ordinary Dao, while "celestial slaying" denotes the reverse course of cultivation practice. Practitioners must use this naturally grown physical body to engage in reverse cultivation, applying the wondrous principle of inverting Yin-Yang to achieve the Great Dao of sages.

The balance of three appropriations:

1. Heaven and Earth appropriate the vitality of all things (all beings flourish and wither according to celestial cycles)

2. All things appropriate humanity's true nature (people become deluded by external objects)

3. Humans can also appropriate the essence of all things (through cultivation and energy gathering)

Only when these three "appropriations" reach equilibrium can the triad of Heaven-Earth-Humanity be stabilized. This resembles alchemical practice requiring nine stages of Yin-Yang energy gathering (corresponding to the nine lines of the Qian hexagram), all depending on the practitioner's precise timing of breath through mouth and nose.

Essential cultivation techniques:

• "Eating at the proper time": Gathering the medicinal energy (primordial Qi) at precisely the right moment, when the entire body feels comfortable and turbid Yin transforms into clear Yang
• One must practice the microcosmic orbit work of withdrawing the Yin tally and advancing the Yang fire, repeatedly refining Jing, Qi and Shen (essence, energy and spirit)
• All these transformations depend on Yin-Yang interaction ("how could one find peace without the feminine" indicates the necessity of Yin-Yang cooperation)

Discernment of spiritual illumination:

What ordinary people recognize as "Shen" (spirit) represents the manifest function of Yang (Yang within Yang). Yet more profound is the "spirit of non-spirit" - the primordial substance that appears non-manifest yet contains wondrous functions. This resembles how the moon itself emits no light (non-spirit) yet reflects solar illumination (thus appearing spiritual). Cultivation emphasizes grasping this seemingly invisible primordial substance.

This scripture primarily elucidates the methods and principles for obtaining "True Yang Qi" in Daoist Neidan (internal alchemy) practice:

The core teaching reveals that True Yang Qi lies concealed within True Yin, requiring specific oral transmission and mind techniques ("direct utterance") to access. Patriarch Lü (Lü Dongbin)'s reference to "mouth to mouth" transmission points precisely to this esoteric mental cultivation. Though appearing ordinary and natural, this practice contains profound mysteries—Wuwei (non-action) harbors purposeful action, while deliberate action resembles non-action.

Acquiring this prenatal Yang Qi (the primordial energy existing before one's physical conception) demands specialized cultivation methods. The text employs celestial imagery to allegorize the "firing times" of practice:

• The sun, though Yang in nature, contains Yin (represented by the Li trigram)
• The moon, though Yin in nature, harbors Yang (represented by the Kan trigram)
• Solar cycles complete in sixteen, lunar cycles in 5,048 (symbolizing cultivation periods)
• "Three before and three after" refers to the coordinated application of celestial stems Jia-Geng and Ding-Ren
• Specific numerical arrangements (like reverse counting by three) symbolize cultivation stages
• Nine such complete cycles are required to attain the state of Pure Yang

When these "firing times" (crucial moments in cultivation) align perfectly, the Qi of the Five Phases converges in the Central Palace (Dantian), producing miraculous effects. Patriarch Pure Yang (Lü Dongbin) and Cui Xifan employed poetic imagery like "heaven's horizon sun-moon" and "ocean-tide bright moon" to encode these alchemical methods.

Key principles:

1. Cultivation requires precise timing in harmonizing Yin-Yang (firing times)

2. Specific mind techniques and sequences gather prenatal Qi

3. Apparently simple practices conceal profound mysteries

The Profound Explanation of the Yin Talisman scripture elucidates the mystery of "stealing celestial mechanisms" in cultivation practice. What is termed "stealing mechanisms" actually refers to borrowing the operational principles of heaven and earth to refine one's own being. Virtuous practitioners who attain this method can stabilize body and mind, while those with unwholesome intentions will instead endanger their vital life—for "stealing" is none other than the "Dao (the Way)," with the crucial distinction lying in its application.

The upper section emphasizes:

Practitioners must concentrate their Shen (spirit) to a single point like a deaf person focusing on sight or a blind person sharpening hearing ("cutting off distractions to unify the source"). This approach can multiply cultivation efficacy tenfold. If one can repeatedly return to the origin three times during day and night practice ("three returns between day and night"), the effect becomes ten thousandfold stronger. Using military strategy as metaphor, this underscores the importance of single-pointed focus and repetitive practice.

Regarding concrete methods:

One must skillfully employ the three senses of mouth, ears, and eyes. First, use ears to listen and eyes to observe celestial timing ("capturing the mechanism"), then coordinate the mouth with specific breathing techniques ("the method of large and small cross-shaped mouth openings") to harvest the true Yang Qi (vital energy) between heaven and earth. Throughout this process, the heart-mind must remain pristine and unmoved by external phenomena ("the heart-mind dies to objects"), like a corpse undisturbed by worldly matters.

The lower section particularly notes:

The life-or-death of the heart-mind depends on mastering external phenomena. If the heart-mind becomes enslaved by objects ("the heart-mind gets dragged by material mechanisms"), though physically alive, one is actually marching toward death. Conversely, if one can harness objects ("using objects as heart-mind's instruments"), the seemingly dead heart-mind attains rebirth. This state of "neither death nor life" must be achieved through observing celestial mechanisms with the eyes, serving as the critical bridge in Dao cultivation.

The Yinfu Xuanjie scripture primarily expounds the Daoist cultivation principles of "Yin-Yang mutual generation" and "reverse cultivation for immortality." Here's a modern interpretation:

The first passage reveals that while Heaven appears emotionless (without grace), it actually contains profound virtue. Sudden thunderstorms and fierce winds may seem violent, yet they manifest the vibrant vitality of Heaven and Earth. The ultimate joy (zhi le) appears deceptively plain (xing yu), while the deepest tranquility (zhi jing) seems bland (xing lian). The Dao of Heaven appears supremely selfish (zhi si), yet functions with perfect impartiality (zhi gong).

The second passage explains the cultivation key: When practitioners transcend worldly attachments (chen qing) and conventional life-death cycles (the ordinary Dao's natural progression), the "Great Medicine" (a Neidan term for refined essence) emerges at the opportune moment (shi zhi ji xian). Here one must distinguish between "Ren-Gui" (Water phase) and "Geng-Jia" (Metal phase), facilitating Metal-Wood fusion before guiding this energy into the Dantian (abdominal energy center). This process returns practitioners to pure Yang constitution (Qian body) for longevity. Lü Dongbin's verse "gaining roots within thunderclaps" describes this moment of sudden awakening.

The third passage employs metaphors: Like cranes mating through song, cultivation emphasizes using Qi (primordial energy) rather than physical form. Without proper technique to circulate energy through the Governing and Conception Vessels, even acquired Qi dissipates. Humans embody half-Yin, half-Yang—cultivation means reducing Yin to augment Yang. Modern people drowning in sensory indulgence (realm of distractions) and depleting vital essence (field of desires) particularly need this Qi-resonance method to return to primordial purity.

The conclusion reveals the core principle: Life-death share common roots; grace-harm mutually transform. Following nature (ordinary Dao) leads to death; reverse cultivation (ni dao) transcends mortality. Ordinary people (sheng ren) lost in passions perish, while cultivators applying these methods reverse conventions to achieve longevity.

This passage thoroughly explains Neidan's "reverse cultivation" principle, emphasizing timely harmonization of Yin-Yang through breath regulation and Qi refinement for spiritual ascension. Terms like Ren-Gui, Geng-Jia, and the Governing/Conception Vessels are all specialized Neidan terminology.

This passage from Profound Explanations of the Hidden Talisman elucidates the mysteries of "life-death transformation" and "fire timing regulation" in Daoist cultivation:

On Life-Death Transformation:

Excessive indulgence in desires depletes Jing (essence), Qi (vital energy), and Shen (spirit) — the three fundamental energies of the human body — ultimately leading to death. Thus, desires are the root of demise. Conversely, overcoming passions and preserving these three treasures brings renewal, making the seemingly negative "death" actually the foundation of life. As Master Ziyang taught: "Treat the gate of death as the gate of life, and never mistake the gate of life for the gate of death." The key to cultivation lies in "moving against the current" — comprehending the Dao of death before bodily decay sets in, thereby attaining true longevity.

On Fire Timing (energy regulation during cultivation):

Just as dragons and serpents must hibernate before soaring, thunderstorms emerge from accumulated Yin-Yang energies. During practice, when internal Qi and blood reach fullness and the Dantian (energy center) shines like the bright moon, seemingly harmful processes paradoxically generate vitality; while outwardly flourishing states may conceal imminent decline. This mirrors lunar phases — extreme Yin births Yang, extreme Yang births Yin — requiring mastery of subtle Xing-De (restraint and generation) balance.

On Observing Celestial Mechanisms:

Ordinary people mistake surface patterns of heaven-earth for divinity, while sages discern celestial secrets through solar-lunar cycles and natural transformations. True mysteries lie not in stellar or geographical appearances, but in grasping nature's laws where "sun-moon follow fixed measures, all things have determined proportions," achieving Tian-Ren Hefa (resonance between human and cosmic energies). Practitioners must perceive these principles within mundane daily life — the crucial pivot between ordinary and sagehood.

Final Warning:

Fools interpret sacred truths with shallow understanding and seek miracles with novelty-seeking minds. Genuine cultivators maintain equanimity, lest they drown yet expect dryness, or enter fire yet hope to escape burning — courting certain ruin. Here "foolishness" refers to the sage's Great Wisdom that appears simple, not actual ignorance.

The Yinfu Xuanjie scripture primarily expounds on how Daoist cultivation must accord with natural laws, opposing artificial striving. Its core message is:

The key to cultivating the Dao lies in grasping the "True One" (primordial Qi). The text employs character analysis to explain this: the character "不" (bu) is interpreted as "one," "奇" (qi) as "standing ready," and "期" (qi) as "its moon"—together signifying that one must quietly stand to receive the Qi of True One during specific celestial hours (its moon). Those who fail to comprehend this essential method and instead pursue the 3,600 heterodox paths or the Three Peaks harvesting techniques (sexual practices) are like those casting themselves into water or fire, courting destruction.

The natural Dao is fundamentally still; in utmost stillness, heaven and earth give birth to all things. When Yin and Yang energies interact, all beings spontaneously transform. This process unfolds on two levels:

1. The pre-heaven phase: The Taiji (Supreme Ultimate), in extreme stillness, generates movement, dividing into the two modes of Yin-Yang, which then transform into myriad beings.

2. The post-heaven phase: The cyclical flow of Yin-Yang energies reaches moments of mutual balance at opportune times, facilitating the growth of all things.

The text particularly emphasizes the importance of "timing," including celestial-human correspondences and the cycles of sun and moon—all fundamental to mastering the firing process (huohou) in cultivation.

Thus, sages understand never to violate natural laws but to align with them. The most sublime cultivation method (qiqi, "marvelous instrument") is concealed within the Bagua (Eight Trigrams) and the sexagenary cycle (temporal-spatial patterns), while the mysteries of Yin-Yang mutual conquest manifest in celestial phenomena.

Finally, it clarifies that authentic embryonic breathing (the foundation of Neidan practice) is not the vulgar understanding of concentrating on the Dantian or forcibly circulating Qi. Rather, one must first experience the harmonious interaction of heaven and earth, then practice the union of water and fire (heart-kidney communion). This consistently reinforces that Daoist cultivation must follow natural temporal sequences without forced striving.

The Profound Interpretation of the Hidden Talisman elucidates the core principles of Neidan (internal alchemy) cultivation:

The essence of practice lies in returning to the primordial state of life within the mother's womb. By unblocking the Ren and Du meridians (the body's front and back energy channels), one enables the circulation of Qi (vital energy) to nourish life. The "ten-mouthed reversed script" mentioned here refers to a specific breathing technique that guides Yang energy downward.

Throughout history, those who achieved immortality and realized the Dao followed this unchanging cultivation principle of Wuwei (non-action). This cannot be mastered through calendrical calculations but requires the "marvelous instrument" (referring to the body's innate alchemical mechanism)—the source of the Great Dao, the root of true Qi, the foundation of all transformations, and the progenitor of the hidden talismans (esoteric cultivation methods). Sages cultivate precisely through this "marvelous instrument."

This "marvelous instrument" is, in essence, the dynamic interplay of Yin-Yang. Its application demands mastery of the "knife and measure" (referring to precise timing and intensity in practice) to manifest its effects. Descriptions like "round, three by five inches and one part" metaphorically depict the instrument's form, yet one should not fixate on literal measurements—it actually signifies specific correspondences among the body's energy cavities.

The Essential Discourse on the Divine Elixir systematically outlines the stages of the Golden Elixir path:

1. Initial stage: Refining Jing (essence) into Qi—Following the principles of the Yijing and the Hetu-Luoshu diagrams, transforming postnatal essence into prenatal primordial energy.

2. Intermediate stage: Refining Qi into Shen (spirit)—Uniting primordial energy with the heart-mind to complete the gathering of medicinal ingredients and forming the elixir.

3. Advanced stage: Refining Shen to return to emptiness—Nurturing the sacred embryo to ultimately attain transcendent spiritual transformation.

Throughout this process, one must skillfully alternate between "Yang fire" (intense heat) and "Yin talisman" (gentle heat). The scripture concludes with an impassioned reminder: The classics and methods of immortality lie plainly before us; the mysteries of cosmic creation are clearly revealed—how can practitioners not diligently apply themselves?

This passage elucidates the Daoist Neidan (internal alchemy) practice of "Embryonic Breathing" (Taixi), which centers on cultivating prenatal Qi (vital energy) through specialized breathing techniques and mental guidance. The method unfolds as follows:

First, one must unblock the Conception and Governing Vessels (Ren and Du meridians)—the body's primary energy channels running along the front and back—allowing true Qi to circulate like a revolving wheel. Practitioners should sit cross-legged with eyes slightly closed ("lowered blinds"), fists gently clenched, withdrawing sensory engagement to gradually enter a self-forgetting state. Through "ingesting golden energy at the fifth watch and consuming celestial fruits at three appointed hours" (specific temporal energy-gathering techniques), one establishes the foundation and clears meridian pathways.

Authentic Embryonic Breathing transcends ordinary nasal respiration, requiring return to the prenatal state of "before one's parents conceived us"—the primordial energetic condition of life. The practice involves mastering the mysterious process of "emerging from nothingness into being, then returning from being to nothingness," focusing on the Dantian (lower abdominal energy center) without forceful attachment.

The text particularly emphasizes receiving authentic oral instructions to avoid misinterpretation. Practitioners must maintain "emptied mind and fulfilled abdomen" (humility with abdominal relaxation), allowing Qi to flow naturally without artificial manipulation. As for alchemical techniques like metallurgical transmutation (Huangbai methods), these belong to more advanced esoterica—yet without mastering Embryonic Breathing and opening the primary meridians, ultimate success remains unattainable.

Cultivators must preserve mental purity: abstaining from deceit, envy, delusion, and doubt to reach a state beyond self and objects. Success or failure should follow natural course without coercion.

This scripture expounds on the Daoist practice of "embryonic breathing" (taixi), revealing that while Confucianism, Buddhism, and Daoism use different terminology ("walking courtyard" in Confucianism, "celestial cycle" in Daoism, "dharma wheel" in Buddhism), their core cultivation principles are fundamentally aligned. All alchemical scriptures point to the same truth, while the other 3,600 heterodox paths deviate from the fundamental principle of Yin-Yang harmony and cannot achieve the genuine Golden Elixir (jindan).

Authentic cultivation requires dual cultivation of nature and life (xingming shuangxiu) — the simultaneous refinement of body and mind. This method traces back to the Yellow Emperor and was transmitted by Laozi to the Buddha when he departed westward through Hangu Pass. Notably, both Laozi and the Buddha maintained household lives, as clearly recorded in historical texts, demonstrating that spiritual practice need not be bound by formalities. Regrettably, later generations artificially divided these three teachings, fostering mutual criticism despite their shared origin.

Embryonic breathing unfolds in three stages:

1. Elementary "refining essence" (lianjing): As gentle and natural as a deer swaying its tail

2. Intermediate "refining qi" (lianqi): As deep and slow as a tortoise's breathing

3. Advanced "refining spirit" (lianshen): As focused and tranquil as a crane incubating its egg

The scripture critiques two erroneous practices: the deviant technique of harvesting yin to supplement yang (the "three peaks" method of exploiting others), and the mineral-based elixir concoctions. It clarifies that true cultivation requires no external substances, relying instead on the internal fusion of shen (spirit) and qi. Finally, practitioners are admonished to uphold loyalty and filial piety as foundations, avoiding deception by charlatans who lead seekers astray.

This scripture elucidates the fundamental principles and proper mindset for Daoist cultivation and alchemical practice.

The text first addresses essential aspects of self-cultivation: practicing benevolence and righteousness, abstaining from lust and violent emotions, moderating food intake, avoiding exposure to wind and cold, eliminating greedy desires and delusional thoughts, and freeing oneself from worldly attachments. When one attains such mental clarity, external objects appear nonexistent, even one's own body feels illusory. Maintaining this state naturally leads to comprehension of true principles and profound mysteries. In this condition, cultivation can be practiced anytime—whether walking, standing, sitting, or lying down.

The crux of practice lies in: minimizing distracting thoughts, speaking sparingly, and focusing on nurturing Qi (vital energy). Cultivating one's nature (spiritual refinement) must be paired with cultivating life (physical practices), which in turn requires the practice of the Golden Elixir (Neidan/internal alchemy). One should persist like the deer, turtle, and crane—animals symbolizing longevity—employing the "Sea Bottom Boat" technique (a specialized Neidan method) to achieve transcendence. This approach not only leads to mastery of metaphysical arts but also grasps the fundamental laws of Daoist cultivation.

The author modestly states he is no exalted master, merely recording essential knowledge to clarify orthodox alchemical methods and guide future practitioners away from erroneous paths. Whether others agree or disagree with these views brings him neither joy nor anger, as those truly comprehending the profound principles will naturally discern their validity.

A concluding commentary praises this exegesis for profoundly illuminating alchemical mysteries, with some insights surpassing earlier masters. The commentator notes having known the interpreter twenty years prior—while not achieving supreme attainment, the author was nevertheless a genuine Daoist practitioner. Thus this commentary was included in the Daoist Canon (Daozang) for future inheritors of authentic transmission to verify. This demonstrates that the Southern and Northern Lineages' transmissions (two major Neidan traditions) cannot be comprehended through empty metaphysical speculation alone.

(Note: "Lifu Mountain Hermit" is the author's self-reference, with "Yuanting Retreat" denoting his practice site. "Sea Bottom Boat" is a Neidan term referring to a specific cultivation technique. "Southern and Northern Schools" indicate the two major transmission systems within Daoist internal alchemy.)
