《純陽三書》Vol. 4

This scripture primarily expounds on the universality of the Dao (the Way) and the shared origin of the Three Teachings (Confucianism, Buddhism, and Daoism).

Master Lü Dongbin (one of the Eight Immortals in Daoism) states: What permeates heaven and earth in all places and exists eternally is the Dao; what continues unbroken from ancient times to the present is religious teaching. Thus, sages establish teachings through cultivating the Dao, setting the foundation for heaven and earth while guiding ordinary people. This transmission endures as long as heaven and earth themselves, yet since the cosmos remains incomplete, it requires realized beings to instruct sentient beings.

Though the Dao is singular, the Three Teachings have developed distinct cultivation paths. Regardless of one's wisdom, social status, or background, all people can comprehend the Dao's principles through sacred teachings. Unfortunately, humans often become deluded by the six sensory faculties (eyes, ears, nose, tongue, body, and mind) in daily life. They know they should follow the Three Teachings' guidance yet fail to practice; they recognize the possibility of attaining the Dao but cannot achieve realization.

Therefore, Lord Laozi (the supreme Daoist deity), compelled by necessity, incarnated in the human realm to leave behind scriptures and miraculous methods for guiding beings. All sentient creatures encountering these teachings naturally feel affinity and acceptance—how much more so for humans? Though people's innate endowments differ, all can transform through instruction. Those with superior predispositions should devote themselves even more earnestly to cultivation.

There are three paths of practice (Confucianism, Buddhism, Daoism), yet no living being exists beyond these Three Teachings. The sages of all traditions use the Dao to deliver beings, though whether one receives deliverance depends on six conditions: aspiration, conduct, destiny, opportunity, blessings, and virtue (De). Among these, destiny is innate and opportunity stems from past karma, but aspiration, conduct, blessings, and virtue can all be cultivated through personal effort.

If one perfectly fulfills all six conditions, becoming either a sage within worldly teachings or an immortal through the Daoist path becomes equally possible. The essential point lies in self-cultivation rather than excessive differentiation between religious affiliations.

In Buddhism, saints are called patriarchs or Zen masters—is such a state solely determined by heavenly decree, or is it the result of human effort? Between heaven and humanity, can one truly attain a state of no-mind and no-thought?

The human heart is like a single inch of numinous light, without fixed form or image, yet capable of merging with the transformations of heaven and earth and gathering the essential teachings of Confucianism, Buddhism, and Daoism. What cultivators cultivate is precisely this numinous light. Though the human body is composed of a hundred bones, it is like a puppet made of paper and bamboo. Only when this numinous light exists does the body have movement and perception; once the light vanishes, the flesh, skin, and hair decay, and sensory awareness disappears with it. Therefore, throughout the ages, those who understand this principle among Daoist practitioners mostly abandon the physical form to pursue the numinous light. If one becomes attached to the body and loses the light, they fail to realize that when the light dissipates, the body cannot endure alone. Confucius once lamented that the great Dao was neither understood nor practiced—the same holds true for our traditions of immortals and Buddhas.

Now we are in the midst of heaven and earth’s true kalpa (a Daoist term for the calamities of the Dharma-ending age), and the truth of Daoism must be clarified. Prophecies (chèn) were issued long ago, and those who appear later fulfill them—all for the purpose of rectifying the errors of the times, delivering people from calamity, and transmitting the Dao to save humanity. This is no ordinary matter.

This is the very moment when heaven and earth reveal the mysteries of the Dao. I must guide my disciples to fulfill the prophecy of the celestial immortals (Duxian). Regarding the essential principles of the Golden Elixir (Jindan) and the regulation of fire times (huohou, the internal alchemical control of heat and timing), I will now explain in detail. The Daoist methods I transmit are not my own invention but originate from the ancestral source of heaven and earth—the fundamental intent of the Supreme Venerable Sovereign (Taishang). Throughout countless kalpas, many realized beings have relied on this to transcend the mundane and enter sagehood. In the Jin Dynasty, the celestial immortal of Yuzhang ascended from the Western Mountains, inaugurating the lineage and leaving behind the prophecy of Longsha (a key Daoist prophecy), which foretold an opportunity 1,200 years later. Now is the time of its fulfillment—the Dao of Heaven does not begrudge the true teachings.

Out of compassion, the Supreme Venerable Sovereign appointed me as the teacher of the disciples in Yuzhang. In the year of Jiazi, I received the mandate of the Celestial Emperor and first established a lineage at the Hall of Welcoming Immortals. Now that the time is ripe, the grand assembly of the true Dao is about to flourish. Thus, I hasten to guide you first—to rescue the world from calamity and establish life for the people. This is no accident.

When I studied under Zhongli Quan (one of the Eight Immortals of Daoism), I once learned the method of visualization (cunxiang, a contemplative practice), which was originally a technique for beginners. Yet today, eight or nine out of ten Daoist students cling to visualization and end up mired in heterodox methods. For novices, it can be used to rein in scattered thoughts, but once those thoughts are stilled, one must apply true effort—generating being from non-being, stirring movement within stillness. These shifts between movement and stillness may seem without pattern, yet they secretly align with the natural cycles of waxing and waning (xingde, the interplay of Yin and Yang) and the measures of advance and retreat. It appears as if there is a predetermined law, yet it is not artificially contrived—this is the state of attaining the Dao. Only after attaining the Dao can one cultivate; only after obtaining the medicine (neidan terminology, referring to Jing, Qi, and Shen) can one form the elixir; and only after the elixir is complete can one nurture the sacred embryo (a high stage of internal alchemy).

Cultivation is actually quite simple—the key lies in relinquishing worldly attachments. If one can resolutely sever mundane ties, they will swiftly transcend the ordinary world and behold the Celestial Emperor (the supreme deity of Daoism). What people commonly refer to as the doctrine of punishment and virtue (刑德) is fundamentally the dialectical relationship between life and death. The Scripture of the Hidden Talisman (阴符经) particularly emphasizes the character "return" (返) when discussing the mechanism of life and death—a principle of profound subtlety.

Heaven and Earth operate according to their own rhythms: spring brings growth, summer nurtures, autumn harvests, and winter stores. The Five Phases (Wood, Fire, Earth, Metal, Water) inherently contain this natural cycle of life and death, as the Dao of Heaven manifests alternating phases of creation and dissolution. Ordinary people follow this cyclical pattern, living and dying in turn, while those who cultivate immortality seek to reverse the Five Phases to attain the state of neither birth nor death. This is the core meaning behind the doctrine of punishment and virtue.

Understand this: the profound mystery of transformation within the human body lies in the space between breaths—within vitality (生机) lurks the potential for destruction (杀机), and within destruction, new life is nurtured. Nourishing vitality can lead to longevity, and transforming destructive forces can also lead to immortality. This is the true essence of transcending the Five Phases and rising beyond the Three Realms (the realms of desire, form, and formlessness). The Triple Concordance (参同契) warns of the need for caution when "punishment and virtue arrive at the gate"—this "gate" indeed refers to the critical threshold in cultivation.

The method of cultivation is truly straightforward: recognize your true nature. Heaven and Earth nurture me, parents give me life, siblings and family accompany me, friends treat me kindly, and others coexist with me—yet none of these relationships fundamentally affect my true self. In life, they cannot truly help me; in death, they cannot take anything with them. If others draw close, I am not overly moved; if they drift away, I do not grieve. If you regard yourself as gold and jade, and external things as mere dust, you will naturally avoid mistaking the trivial for the essential. The Dao of Heaven naturally rewards those who do good—there is no need to worry about whether today's cultivation will bear fruit, only whether neglecting it now will deprive you of future blessings. Cultivation is a personal journey—no one can compel another, so why should I distress myself over it?

The immortal realms hold the joy of eternal life, yet the human world also offers many pleasures: high rank and generous stipends, halls filled with jewels, towering mansions, illustrious lineage, brothers accomplished in both civil and martial arts, descendants blessed with honors, the power and prestige of kings and generals, and enduring fame in history—these are the pinnacle joys pursued by worldly people. Yet those who follow the Dao choose instead to retreat to mountain forests, transcending worldly concerns, neither submitting to emperors nor befriending lords, content to abide in the Dao and follow the mandate of Heaven.

At home, one harmonizes with the seasons to savor life, experiencing the beauty of familial harmony; abroad, one mingles with like-minded friends, as free and unconstrained as heaven and earth. Making companions of the clear breeze and bright moon, roaming mountains and springs with deer amidst rocks—so carefree it’s as if one forgets the vastness of sky and earth. When body and mind are in perfect balance, and the heart sheds worldly troubles, this is the eternal joy of a true noble spirit.

Yet this speaks only of worldly happiness. To advance further in pursuit of the Dao (the Way) brings boundless joy. The key to cultivation lies in personal effort—when human affairs are perfected, the heart of heaven naturally reveals itself. The state of the world depends on whether the court has wise rulers and virtuous ministers who bring harmony to the land and peace to the people; the prosperity of a family rests on its head, but its foundation lies in self-cultivation and rectifying the heart. The heart governs the body, and thoughts are its function. Simply maintain upright thoughts and a tranquil heart, and external distractions cannot intrude—the body will naturally follow your guidance. In this way, one can resonate with the nine heavens above and penetrate the nine abysses below (symbolizing the poles of heaven and earth). Even spirits and deities will align with your will, and all things will heed your direction. Transforming misfortune into blessing, or turning auspiciousness into calamity—all depends on oneself. How could it be left to heaven’s arrangement? Even the Creator cannot constrain such a person, let alone whether spirits obey or not.

What I speak of here is the most fundamental truth. Those who study the Dao may begin here to attain immortality; those who follow Buddhism may cultivate here to become sages or worthies. It preserves both heavenly mandate and human affairs. As for the scheming and pursuit of fame and profit beyond this, I disdain to know. The teachings of the sages of Confucianism, Buddhism, and Daoism are all recorded in their scriptures. Why do later generations turn a deaf ear, acting blindly and recklessly, deceiving in secret? They feel shame in solitude yet still gloss over their faults to mislead the world. Little do they realize that with every thought arises, spirits and deities bear witness. Once good and evil are distinguished, fortune and misfortune follow immediately—how terrifying! These words are warnings for ordinary people, but practitioners must be doubly cautious.

In our Daoist tradition, we emphasize the dual cultivation of nature and life (Xing refers to the mind’s nature, Ming to the physical body). At the beginner’s stage, the focus is on regulating Shen (spirit) and Qi (vital energy); with some foundation, the priority shifts to eliminating distracting thoughts. During the foundational stage, nurturing Qi is paramount; in alchemical practice, harmonizing lead and mercury (Neidan terms for Yin and Yang energies) is key, and in forming the Golden Elixir, mastering the firing process (breath control during practice) is essential. On the path of cultivation, one must neither rush into realms yet unattained nor regress from stages already completed. The Dao is cultivated entirely by oneself—if the heart is disordered, what use is even the most profound teaching from a master?

The cultivation of spiritual practice lies in personal realization. Those who merely imitate others in search of secret formulas are like people trying to find a horse by looking at its picture—they will ultimately be laughed at by the discerning. Only when one verifies their practice through experience and aligns their inner understanding with the wisdom of ancient scriptures, achieving perfect harmony, can they be said to have truly received the master's transmission. Never patch together fragmented teachings or chase novelty while neglecting the fundamentals. Greed for quick results in the foundational stages of practice (Xiaocheng, the lesser vehicle) will only limit one's spiritual attainment. What may seem like a shortcut now will ultimately hinder higher achievements.

Many attain enlightenment before receiving the oral formulas, and even more receive the formulas before attaining enlightenment. Those who possess the formulas without realization will eventually awaken, but those with insight alone, lacking true transmission, will struggle to achieve greatness. The highest principles of the Dao were passed down to me by my master, who inherited them from our patriarch, tracing back to the primordial Dao itself. Like seven lotuses blooming—each with fewer petals—only a rare few truly grasp this wisdom. The spiritual mechanism of Heaven and Earth often begins to manifest in concealment; the deeper it is hidden, the more easily it is realized, revealing itself to the destined only when the time is ripe. This fulfills the prophecy of a thousand years and opens an eight-hundred-year opportunity. To which lineage could this belong, if not ours?

Alas, the unevenness of all things is the natural order, and the operation of the great Dao follows its own principles. Constrained by these principles and bound by circumstance, the Dao cannot fully manifest in all things—is this not the natural way? One must possess blessings, affinity, and heavenly mandate—three conditions—along with action and talent, all five combined, to become an orthodox inheritor of the immortal tradition. Those with only one or two may at most become branch followers or dependents. I elaborate on this to rectify practitioners' resolve, bolster their spirit, and urge them to advance courageously, seizing the moment to achieve the "slaying of generals and capturing of banners" (a metaphor for breaking through cultivation barriers).

The Lingbao Bifa (Complete Methods of Numinous Treasure) was personally compiled by Patriarch Zhongli Quan from the essential teachings of ancient scriptures and transmitted to me to guide later students. It is a path from the lesser vehicle (Xiaocheng) to gradual realization of the great Dao—a pure and authentic method, utterly free from falsehood. Why would I not follow this true transmission step by step in teaching sentient beings? Only because the time is urgent, and Heaven no longer begrudges the Dao, that I, bearing the heavenly mandate, directly point to the highest teachings. Merit lies not in quantity but in natural accomplishment. The lesser vehicle leads from the mundane to the sacred, cultivating from the outside in; my highest formulas are sudden transcendence, enabling direct realization from within to beyond. Those with discerning eyes will understand.

People often discuss the practices of "laying the foundation" (Zhuji) and "refining the self" (Lianji), yet they fail to realize that self-refinement is endless, while foundation-laying has its stages. Self-cultivation must be grasped firmly from the beginning and maintained in purity, with vigilant caution until the day of great accomplishment and liberation (attaining the Dao). Only then is it complete.

This scripture expounds the essential principles of cultivating the Great Dao (Dao) and the proper mindset for spiritual practitioners.

The Patriarch Lü (Lü Dongbin) first points out that the foundation of spiritual practice lies in the principle of "natural ease." True foundational cultivation requires only one hundred days of dedicated effort. Those who believe no cultivation is necessary fail to understand the natural principles by which Heaven and Earth give rise to humanity. If practitioners comprehend this truth, their spirit (Shen) will naturally consolidate, their physical form will remain healthy, and even long-standing ailments and karmic obstacles will be unable to afflict them. The most profound method is to encourage people to relinquish attachments.

The essence of Dao cultivation is constancy—those who study the Dao must maintain single-minded devotion from beginning to end, without wavering. When the mind aligns with the Dao, the Dao becomes the mind; there is no Dao outside the mind. Those who seek quick results often chase lofty but unrealistic goals, while those who pursue the miraculous tend to overlook simple methods. Thus, though countless people study the Dao, very few truly attain realization.

Now, during this extraordinary period of Heaven and Earth’s true tribulation (a major calamitous era), Patriarch Lü transmits the essential teachings of the Great Dao to enlighten sentient beings. He emphasizes that this is not a case of previously secret knowledge being suddenly revealed, but rather a transmission suited to the times and the people. Though the immortals and sages of past dynasties have left behind tens of thousands of alchemical scriptures (Danjing), none compare to direct guidance in the present moment. Those who grasp these principles can attain sagehood.

Patriarch Lü mentions that during his recent audience with the Primordial Heavenly Worthy (Yuanshi Tianzun), the assembled immortals of the Three Isles (Penglai, Fangzhang, and Yingzhou) unanimously entrusted him with conveying the "Great Prophecy of Longsha." Though celestial selection of immortals uses the year of Jiashen as a temporal marker, those who cultivate immortality must accumulate virtue across multiple lifetimes. Yet once reborn in the human realm, they are easily deluded and unaware of their true nature.

Finally, it is explained that this act of salvation (Kaidu) is carried out by the decree of the Heavenly Emperor, intended to deliver eight hundred individuals from calamity. The Great Dao encompasses the transformations of Heaven and Earth, transcending past and present. Heaven and Earth rely on the Dao to function, and the immortals of all ages have attained realization through its cultivation. Without the Dao, Heaven and humanity remain separate; with the Dao, they become one. Those who cultivate and realize the Dao can ascend beyond the celestial realms and roam the Three Isles. Though the distance between Heaven and humanity may seem vast, the moment of resonance is as immediate as a shadow following its form. Patriarch Lü has already submitted a memorial with the assembled immortals in the Golden Palace (celestial court) to the Heavenly Emperor, receiving special permission—all for the sake of propagating the Dao. The Great Dao is inherently complete; by turning inward, one attains it, without need to calculate the length of time.

Cultivation knows no bounds of age or scholarly attainment—what truly matters is maintaining steadfast resolve and an enterprising spirit without a single day of negligence. With persistent refinement and upward progress, the day of attaining the Dao and achieving immortality will be within reach. Consider Zhang Liang (styled Zifang), who comprehended this path to become both a capable minister assisting emperors and, through reclusive practice, an immortal transcendent. Zhuge Liang, though also a royal advisor, remained mired in worldly dust due to his failure to rein in his heart-mind. Practitioners should discern whom to emulate.

The essence of cultivation lies in preserving inner purity and utterly severing desires. One must abstain not only from greed for wealth and lust but also minimize even basic needs like clothing and food. The body requires only subsistence, while the heart-mind focuses inward on the spirit (Shen). When one forgets the body, attention turns to the heart; when the heart is forgotten, focus shifts to the spirit. With body and mind unified, spirit and innate primordial Qi (炁) return to their source—this naturally leads to forming an immortal embryo and coalescing divine energy.

The Celestial Court (Jade Edict) again descends its decree, revealing auspicious signs at the Golden Gate of the immortal realm. The host of perfected immortals recommends the practitioner, and the Three Realms jointly endorse them. When merit and virtue reach fulfillment, they may ascend together to Penglai, the Isle of Immortals. I shall transmit talismanic incantations (Fulu) and water-conjuring secrets to aid cultivation and vanquish demons, as well as elixir refinement to awaken to the Great Dao and liberate form and spirit. Combining these, the Great Dao will flourish, unlocking an eight-hundred-year opportunity and actualizing a once-in-a-millennium juncture. This is no ordinary matter.

The crux of practice lies in apprehending the prenatal, primordial state (before physical life)—this is most challenging. Once life forms, it becomes easier. Cultivation must progress daily, refining itself with time. While adepts may emerge successively, practitioners must remain ever-focused, with not a single thought straying from the true path, to achieve seamless unity. Mysterious states will manifest spontaneously—there is no secret beyond understanding one's internal rhythms of movement and stillness, the timing of Qi's ascent and descent, and the measure of acceptance and rejection. Thus, the work naturally abides in the profound, rendering distinctions of difficulty or ease, speed or slowness irrelevant.

True practitioners at this stage grow even more silent and steadfast, indifferent to life and death, awaiting the spontaneous emergence of the mysterious. Once realized, it is possessed eternally—is this not bliss? The elixir coalesced from the Three Yangs (Jing, Qi, Shen) can be attained within a hundred-day retreat. But first, desires must be severed, essence (Jing) accumulated, and distracting thoughts pacified—then spirit and Qi will naturally commune, and the mystery will readily reveal itself.

The Supreme Venerable Sovereign (Laozi, Daoism's highest deity) bestows teachings, traversing kalpas to deliver beings, inaugurating mysterious methods and elucidating religious truth. Thus, the study of immortality thrives, yet practitioners often treat their masters' instructions merely as provisional tools. True awakening ultimately requires self-deliverance—without it, attainment remains limited. The Golden Elixir (Jindan) is human nature itself—formless, imageless numinous awareness dwelling within the flesh.

Whether human or other living beings, once the physical body is lost, the flesh, blood, and vital essence (Jing-Qi) will decay and dissipate. Thus, the profound secret of Daoist cultivation lies in first constructing a framework of essence and Qi (Jing-Qi) within the mundane body—a skillful creation of an additional space within the four elements (earth, water, fire, and wind) that form the physical form—to serve as the dwelling place of the primordial spirit (Yuanshen).

After ten months of practice, this Jing-Qi framework takes initial shape, though the primordial spirit (the master) has yet to take residence. At this stage, the physical body and the spirit remain separate entities. Practitioners must grasp the crucial moment to guide the spirit to settle within. They must persistently seek the path into this space, refining their focus through meditative stillness until the time is ripe. Then, it will be as if seated within a crystalline ice vessel, soaring beyond the clouds in transcendent freedom—this marks the true attainment of a dwelling for the primordial spirit.

Once the spirit is settled, one naturally reaches a state beyond deliberate coming and going, unified and whole, with the six senses purified and all consciousness returning to stillness. The body relaxes as if intoxicated, the mind liberated, nearly forgetting the existence of heaven and earth, transcending natural laws—this is the state of a "spirit-person" (Shenren). Here, the primordial spirit is fully stabilized, nourished like an infant by its mother, until the Heavenly Gate (Baihui point at the crown) opens naturally, revealing the true spirit. Though a new form manifests beyond the physical, the practitioner must still anchor the mind and delve deeper into the mysteries.

Internally nurturing the spirit and externally refining the form—these two disciplines must be practiced ceaselessly, morning and night. The method of harmonizing the spirit follows specific rhythms and can proceed in tandem with refining the body. After one year of dedicated practice, the true Qi (Heche, the "River Chariot") will circulate ceaselessly within; after five years, the Qi stabilizes completely, and the body begins to transform; after seven years, form and spirit merge; and after nine years, the body fully dissolves into the spirit. At this stage, the primordial Qi (Xiantian Yiqi) gathers and disperses at will, with no hindrance to ascending to heaven or descending to earth.

The key to cultivating primordial Qi lies in returning spirit and Qi to their root in a state of utmost emptiness and stillness. When Yang energy arises from the southwest (Kun position), it resembles the moon residing in the toad palace (a metaphor for the Dantian), known as the "true seed" (Zhen Zhongzi). Once the generative Qi is abundant, it is gradually gathered and elevated, forming a state of the Tai hexagram (balance of Yin-Yang) in the abdomen. During the first quarter moon (around the seventh lunar day), metal and water mutually generate; two solar cycles yield the "medicine" (Neidan, the internal elixir), and four cycles complete the firing process (Huo Hou), alternating gentle and intense heat. In a fleeting moment, lead and mercury (symbolizing spirit and Qi) fuse, the Yang fire peaks and shifts to Yin sealing (cooling and nurturing), like the infant (spirit) and the maiden (Qi) meeting in the Yellow Court (middle Dantian). When clouds disperse and winds calm, the dragon and tiger (heart-mind and kidney-Qi) return to their positions, revealing a millet-sized luminous pearl (the inner elixir) illuminating the void. Simply maintain Wuwei (non-action) and hold to the center, harmonizing spirit and breath in walking, standing, sitting, and lying. Persist through the foundational 100-day practice and the 10-month "gestation" (inner alchemical cycles) until nature and life (Xing-Ming) are perfected, transcending the mundane. A true cultivator who reaches this stage may inscribe their name among the immortals.

This passage elucidates the core principles of Daoist cultivation and the path to immortality. The fundamental essence of internal practice lies in grasping the "Great Center" (the primordial Dao of cosmic origin), which existed prior to Heaven and Earth and gives birth to all things. Attaining this foundation allows one to comprehend the true nature of Dao, from which Yin-Yang differentiation emerges.

Cultivation requires harmonizing the Three Treasures (Jing, Qi, Shen) and blending the Five Phases (Metal, Wood, Water, Fire, Earth), while absorbing the essences of sun and moon to nurture the Mysterious Feminine (the foundation of Dantian). Through repeated opening and closing of energy portals and circulating the cosmic forces within, one refines the inner Shen (spirit) to greater purity. Transcending worldly attachments leads to becoming a Zhenren (Perfected Being). Practitioners must master "fire times" (the precise regulation of alchemical processes) - these profound principles require direct oral transmission from master to disciple.

External alchemy (Waidan) involves gathering the dual energies of Yin and Yang, a secret method transmitted between heaven and humanity. One must extract the solar and lunar essences (the crow symbolizes the sun, the hare the moon) through repeated refinement. The Flame Emperor (Shennong) possessed this knowledge. A single Golden Elixir pill (measured by ancient medicinal spoons called daogui) becomes priceless, requiring three years and nine cyclical transformations to achieve divine efficacy. This elixir exists between being and non-being, elusive to grasp. When merits reach perfection, ingesting the pill enables ascension to the Great Canopy Heaven (the highest Daoist celestial realm), where both form and spirit transcend - even enabling one's domestic animals to ascend together.

Cultivation requires balanced internal and external practice without neglect. Since ancient times, few have truly attained the Dao. Now these teachings are transmitted to destined recipients who must engrave them in their hearts.

Time and phenomena constantly transform; one must accord with celestial timing and observe the changes of all things to comprehend Qi's operational patterns. Sages thoroughly understand these principles. Ordinary people muddle through life - human existence as brief as sparks from flint or lightning, fleeting as a dream. Therefore sages sigh with compassion.

Dao practitioners must establish their resolve in self-cultivation, pursuing transcendence to sagehood. With the "square-inch heart" (the field of consciousness), they comprehend the most profound mysteries, using their bodily vessel to perceive the arcane principles of Heaven, Earth and Humanity. Those who hear the Dao in morning and attain realization by evening are true kindred spirits. If the mind lacks focus, obstructed by external conditions, even oral transmission becomes like autumn wind passing the ear. Advancing toward Dao and De (Virtue) while retreating into worldly temptations creates inner conflict that leads astray. Though claiming to study the Dao, such practitioners never truly enter the gate.

The passage concludes noting Liu Zi's profound discourse has already explained these matters with exceptional clarity, intending widespread teaching. The supreme principle takes wisdom as fire and meditative stability as water (indicating cultivation requires both wisdom and concentration).

The essence of cultivation lies in maintaining focused awareness of the True Intention (innate consciousness), with breathing that is natural and balanced—neither excessive nor insufficient. By persistently maintaining this state, the genuine Qi (Dan fire) within the body gradually circulates, refining the Jing (life essence) into a purer form. After ten months of practice, the Yang Spirit (higher form of the Original Spirit) will manifest in form, enabling ascension to the Jade Pure Realm (one of the Three Pure Heavens). However, one must never forget the fundamental roots.

The cultivation process unfolds in distinct stages: First, nourish the body with Jade Nectar (saliva) and Golden Essence (kidney Jing). Three years of dedicated practice lead to a state of inner and outer emptiness, while twelve years of complete cultivation allows one to answer the celestial summons to the heavenly realms. Specific attainments vary by individual—three years without Jing leakage results in forming the Elixir in the lower Dantian, six years in the middle Dantian, and nine years in the upper Dantian. As for the higher realm of "Spirit Returning to Emptiness," even longer cultivation is required, marking the distinction between Earth Immortals and Celestial Immortals.

Authentic Daoist practice requires the dual cultivation of Xing (spiritual nature) and Ming (physical life), with the highest attainment being the Way of the Celestial Immortal. Teaching methods vary—some begin with Xing cultivation, others with Ming—but ultimately both must be perfected. Realization of spiritual nature depends on personal awakening, with masters providing only guidance; whereas Ming cultivation requires direct transmission, including precise knowledge of acupoints, ingredients (Jing, Qi, Shen), methods, and fire regulation—otherwise errors are likely.

This path differs from ordinary religion, recognizing no hierarchy or sequence—only the practitioner's virtue (De) and skill matter. The Dao of Heaven shows no partiality, favoring only those with virtue. Those who perfect their merit are called Zhenren (Perfected Ones), those who manifest miraculous transformations are called Shenren (Divine Persons), and those fully united with the Dao are called Zhiren (Ultimate Persons).

The human heart-mind has two aspects: the desire-driven mind of fleshly senses, and the innate luminous True Mind. The True Mind requires the ordinary mind as its vessel. What the eyes see stirs thoughts; the mouth is the mind's external outlet; hearing and seeing equally arouse desires—these three are crucial in mind cultivation. Daily life demands rectified mental states and careful attention to seeing, hearing, and speaking: in action, attend to details; in stillness, guard the root. With sustained effort, the longer one practices, the purer the skill becomes—completing most of the work. Affinities for the Dao are supremely precious and must be deeply cherished.

This scripture expounds the highest state of immortal cultivation, emphasizing that true Daoist practice does not lie in pursuing worldly wealth and longevity, but in comprehending the fundamental source of the Dao.

Patriarch Lü (Lü Dongbin) points out: The most precious Daoist methods cannot be obtained through forceful seeking—they require predestined affinity. If this affinity hasn't matured, all striving will be in vain. The authentic superior cultivation method involves: steadfastly establishing one's foundation over a hundred days to stabilize Jing (essence) and Qi (vital energy), undergoing the ten-month "gestation period" (referring to the "sacred embryo" stage in Neidan/internal alchemy practice) to manifest the Yang Shen (spirit), nurturing the bodily transformation through three years of refinement, ultimately achieving a state beyond hunger and cold—one of carefree liberation. After completing the nine-year, nine-cycle celestial orbit cultivation, one may ascend to the immortal realms—this is no ordinary longevity technique comparable to minor methods.

Worldly people pursue nothing but wealth, power, longevity, descendants, and fame, yet all these are unreliable. Wealth is hard to obtain, lifespan has limits, descendants may not achieve greatness, and fame vanishes in an instant. Rather than indulging in these, one should aspire to transcend the mundane and seek the true Dao transmitted by ancient sages like Fuxi and the Yellow Emperor, becoming an immortal wandering freely through the cosmos. Though vast, heaven and earth cannot constrain those who attain the Dao—why then concern oneself with worldly honor and disgrace, the life and death of the physical body, or the vicissitudes of the age?

The key to transcending the mortal form lies in discovering the "Mysterious Pearl" (referring to the crucial acupoint in Neidan practice). This acupoint is the foundation for becoming an immortal or Buddha, the basis for forming the Golden Elixir and achieving spiritual rebirth. Without locating this pivot, cultivation becomes like viewing a needle's eye through a wall or fishing for the moon in water—mere delusions. Authentic Daoist practice requires "dual cultivation of nature and life" (xingming shuangxiu), but prioritizes cultivating one's nature. The mind is the root—where the Shen (spirit) resides manifests our primordial nature, all inseparable from this "heart aperture."

The heart aperture discussed here differs from ordinary orifices—it refers to the primordial aperture at the dawn of chaos. This aperture simultaneously exists and doesn't exist, transcending dualities of being and non-being, embodying the wondrous reality of absolute emptiness. Grasping this fundamental aperture establishes the foundation of cultivation. Understanding this principle means one can become an immortal if one wishes, or attain Zen realization if desired. The supreme method of cultivation is to transcend attachments to both spirit and physical life, returning to the original face of Wuwei (non-action) and natural spontaneity.

Note: The terms "hundred-day foundation," "ten-month gestation," and "nine-year nine-cycle" are all Neidan terminology referring to different stages of practice; the "Mysterious Pearl" indicates either the Dantian (energy center) or the mysterious gate—the crucial point in Neidan cultivation.

This scripture expounds the core methods and states of attaining immortality through Daoist cultivation. The foundation of practice lies in achieving perfect luminous clarity of mind (xing yuanming), which enables realization of the Golden Immortal (the highest celestial rank). Practitioners must undergo the ten-month retreat (shiyue juyuan), a process established by the Eastern Florescence Emperor (Donghua Dijun, a principal Daoist patriarch) that all destined achievers have followed through countless kalpas.

The crux of cultivation lies in seizing the "yang birth" moment: gathering primordial yang qi (xiantian yangqi) and continuously nurturing it (cai zhi yang zhi). After the hundred-day foundation establishment (bairi jizhu), the mysterious feminine-masculine junction (xuanpin) within the body becomes firmly established, marking the completion of the divine chamber (shenshi) - the internal space for alchemical work.

When the xuanpin stabilizes, practitioners enter a transformative state: breathing becomes suspended yet present (xi zhu yu tai), meridian activity approaches stillness (mai ju ting), and through inner vision (neishi fanzhao), one perceives with crystalline clarity the internal landscape (neijing langran). At this stage, the true cauldron and furnace (zhen dinglu) - the energetic system - manifests completely. The yang qi ascends while yin qi descends with perfect precision, accompanied by wondrous visions (white snow filling the void, golden sprouts covering the earth).

After ten months, the yang spirit (yangshen) emerges, sometimes dancing between the three passes (sanguan) or surging upward. When practice matures, it suddenly bursts through the celestial gate (baihui point), revealing an infant-like yang spirit - marking the completion stage (gong quan). Yet higher cultivation continues toward the state where form and spirit both attain subtlety. Ultimately, practitioners return to the void origin (fanxu), merging with heaven, earth and all things to transcend life and death as celestial immortals.

The scripture particularly emphasizes that the Golden Elixir (jindan) embodies the true yang concealed within the Kan trigram (one of the Eight Trigrams). Practitioners must understand Dao's essence (ti) and function (yong): empty numinosity is the essence, wondrous response the function. Although jing (essence), qi (vital energy), and shen (spirit) are crucial, one must not cling to any single aspect. Some err by indulging in empty theorizing (kuchan) or fixating solely on physical cultivation (wanqu), both deviations from the true path. When Patriarch Lü (Lü Dongbin) delivered eight hundred disciples, only those who grasped this supreme cultivation method attained celestial immortality.

This scripture expounds the core principles and progressive stages of cultivating immortality. Patriarch Lü (Lü Dongbin) reveals that the key to spiritual practice lies in balancing "method" with "essence and function." The foundation of divine cultivation resides in harmonizing the spirit (Shen) with vital energy (Qi). Human life is fundamentally composed of Yin and Yang energies – understanding how to refine these enables transcendence beyond cosmic constraints, returning to the primordial unity with all existence.

However, the path of cultivation is fraught with difficulties, primarily because most people lack sufficient spiritual merit. Only those with unwavering resolve and courageous determination can alter celestial destiny, penetrate the mysteries of Dao, and surpass the cycle of life and death – such practitioners embody the true "great person" of Daoist cultivation. All immortals were originally ordinary humans; the crucial difference lies in maintaining transcendent aspiration through all trials without losing one's original intent.

The practical cultivation process unfolds through distinct phases: the initial hundred days establish foundations through gathering medicinal energies (accumulating Jing and Qi), followed by two hundred days forming the golden elixir (condensing Neidan) and creating the spiritual embryo. After three hundred days of refinement, the practitioner achieves embryonic liberation (nurturing the Yang spirit), culminating in the Yang spirit's emergence from the body (creating a transcendent form) after ten lunar months. Yet even at this advanced stage, practitioners must continue until form and spirit completely unite with Dao to attain genuine perfection – anything less results in the "five false fruits" of incomplete attainment.

An alternative accelerated path exists: accumulating virtuous deeds and merit may invoke celestial beings to bestow an elixir of immortality, enabling immediate ascension upon ingestion. Those with extraordinary merit may even bring dozens of family members to celestial realms. Regardless of method, ultimate achievement depends wholly on the practitioner's aspiration and diligent effort.

Daily practice should follow the principle of "using spirit to command Qi, using Qi to preserve form." Ordinary cultivation employs post-heaven consciousness to regulate breathing and nurture the body, but the truly crucial "sacred work" requires achieving the void-serenity state where body-mind unifies and both spirit and energy are forgotten. In this condition, primordial Yang energy spontaneously arises – the gathering of medicinal substances and elixir refinement operate through innate instinct. Practitioners must learn to follow natural rhythms: acting without coercion when movement is required, stopping without compulsion when stillness is needed. Here, the term "intent" refers not to ordinary consciousness, but specifically to the primordial true intent described in the Mirror for Compounding the Medicine scripture.

This passage elucidates the core Neidan (internal alchemy) concepts of "True Earth" and "Heavenly Mechanism" in Daoist cultivation.

The practice holds that "True Earth" (referring to the body's innate primordial Qi) serves as the foundation of the Five Phases (Wood, Fire, Earth, Metal, Water) and the source of all things—the very ladder to immortality. The Yin-Yang transformations within the human body contain the mechanism of life and death. As the progenitor of alchemical scriptures, the Yinfu Jing particularly emphasizes the principle of the "death mechanism."

The movement of heaven and earth pivots around the Big Dipper as its axis, governing seasonal transitions and the cycle of life—hence the phrase "heaven activates the death mechanism." Similarly, the human body contains its own Dipper-like mechanism: when still, all Shen (spirit) return to their positions; when active, heaven and earth may invert. This constitutes the "human activation of the death mechanism." The emphasis on "death mechanism" rather than "life mechanism" stems from the interdependent relationship between life and death within nature's ceaseless generative cycle.

Many misinterpret the term "death mechanism," reducing it to mere Yin-Yang alternation or the coming and going of thoughts—both misunderstandings. "Waxing and waning" (referring to Yin-Yang fluctuations) represents this very mechanism of change, which cannot be simplistically equated with breathing or movement. Just as objects contain pivotal joints, so too does the human body possess such critical loci—understanding this reveals the true meaning of "waxing and waning."

Earth's operational mechanism manifests through seasonal changes, moving in accordance with heavenly patterns. Thunderclaps and the dormancy of dragons and snakes all reveal the profound workings of cosmic movement—whose essential pattern follows the Big Dipper's orbit. The human body, sharing heaven and earth's characteristics, likewise takes the Dipper as its pivot.

The author references his poetic line: "The Mysterious Pass is the single aperture of life's mechanism." When this Mysterious Pass (the body's crucial energetic cavity) reveals true intent, the Heavenly Mechanism activates. Comprehending this principle makes the dual cultivation of nature and life (Xingming Shuangxiu) as effortless as reaching into a bag to retrieve an object.

What the human mind perceives are thoughts and consciousness; what remains unseen is the original substance of Shen (spirit). Dao practitioners must seek their true mind through enlightenment—seeing this true mind constitutes seeing the Dao. What Chan Buddhism describes as "the golden countenance of the full moon," and what alchemical texts call "the blazing sun at midday," the "Golden Elixir" (Jindan), or "Vajra body," all point to this fundamental substance.

The mystery of immortals lies in using the three medicinal substances—Jing (essence), Qi (vital energy), and Shen (spirit)—to nurture the embryonic Dao. When true mind manifests and nature-life unifies, one attains the divine abilities of celestial beings: traversing heaven and earth, penetrating metal and stone—this is the realm of transcendence.

When the sun rises, those cultivating the celestial immortality path begin their practice. The foundation of cultivation lies in this single heart-mind—if one's thoughts remain pure, why cling to formal precepts or purification rituals (Zhaijiao)? Why must one renounce worldly ties? Every place can become the meditation mat for seated cultivation. Our Daoist tradition in guiding humanity originally emphasized direct mind-to-mind transmission between master and disciple, requiring little verbal explanation.

Yet the profundity of the Great Dao (Dao) remains elusive, and the gap between immortal and mortal realms resembles an impassable chasm. Without the opportune guidance of celestial beings, true attainment proves difficult. Only by necessity have these methods of salvation been established. When cultivation reaches completion and the Great Dao is realized, lineages naturally form and flourish. During the Final Kalpa (true劫), grand dharma assemblies will propagate the teachings widely—this is my aspiration and the ultimate fruition for all practitioners.

The mysteries of refining the Golden Elixir (Jindan, internal alchemy/Neidan) cannot be grasped through ordinary learning. Since the separation of heaven and earth, all patriarchs and realized beings have comprehended supreme truth by uniting the cosmic secrets of creation with the inner principles of the human body. Like Nüwa's five-colored stones that mended the heavens or the Yellow Emperor's elixirs cast in nine cauldrons (legendary alchemical feats), these embody profound subtleties. Later generations of cultivators transmitted this knowledge across ages, leaving clear traces between heaven and earth—from emperors to commoners, all sought to study this alchemical art.

But celestial treasures are extraordinary, and secret formulas are never lightly revealed. How could their complete mysteries be fully recorded in books for casual viewing? When I first established teachings for eight hundred disciples in Yuzhang (modern Nanchang, Jiangxi), I merely pointed to the Mysterious Pass (Xuanguan, a key energy point in Neidan) to illuminate the Dao's essence. Only now do I transmit concrete elixir-refining methods to fulfill this salvational opportunity. The Great Dao originates from the Primordial Beginning (Taichu)—it is no private possession. Affinities require accumulations across lifetimes, not mere chance encounters in this life.

The Immortal Du (Xu Xun, Jin Dynasty master) established his merit during the Jin era, leaving prophecies that endure today. Emerging centuries after him, I vowed before our master to deliver all destined beings. In this extraordinary era, the Celestial Emperor has entrusted me with this salvational mission, awaiting those whose virtue and practice reach completion. I shall broadly guide fellow seekers to jointly accomplish this great work. When internal and external Golden Elixirs (Neidan and Waidan) are perfected, the moment for celestial ascension arrives.

In essence, the myriad buddhas and sages share one heart-mind and one Great Dao. Purity of heart reveals the Dao; immortals and buddhas ultimately return to the Heavenly Way. Heaven selects suitable candidates—when human hearts align with the celestial mind, the elixir seed matures, and the immortal fruit naturally forms through ten months of internal refinement and one year of external work. As climbing high begins from low ground and distant journeys start nearby, once the elixir foundation (Dantou) ripens, it undergoes nine cyclical refinements (Jiuzhuan Huandan). After cinnabar purification, nine more years of nurturing follow. Merit towers like Mount Tai; grace blankets heaven and earth.

When eight hundred disciples first gathered at Longsha (legendary site of Xu Xun's ascension), three groups already ascended to the Jade Palace (celestial court). This exemplifies the great undertaking of noble beings—the blissful realm of companionship with immortals.
