《伍真人丹道九篇》

The "Origins" section of The Nine Chapters on Alchemy by Master Wu recounts the transmission process of this classic:

Master Chongxu (the Daoist name of Wu Shouyang) first transmitted the oral formula for "Refining Jing (Essence) in One Hundred Days" to Prince Ji Taihe in the year 1615 (Wanli reign, Yimao year). Seven years later (1622, Tianqi reign, Renxu year), he taught the formula for "Gathering the Great Medicine." After another six years (1628, Chongzhen reign, Wuchen year), he imparted the method of "Five Dragons Holding the Sacred." Later, Taihe requested the complete teachings of "The Unified School of Immortals and Buddhas," but permission was initially denied. Only four years later (1632, Chongzhen reign, Renshen year) did Chongxu agree to transmit it, fully revealing the profound principles of "The Unified School of Immortals and Buddhas" through a question-and-answer format. He also passed on the symbolic talisman (a Daoist transmission token) of the orthodox lineage from Patriarch Qiu (Qiu Chuji, the Eternal Spring Master). Due to Taihe's meticulous questioning and Chongxu's detailed responses, the teachings were eventually compiled into nine chapters. Chongxu specifically instructed that these methods, being the supreme treasures of Heaven, should only be transmitted to virtuous and worthy individuals with shared aspirations and ancestral merit, and must never be casually given to those of dubious character. This classic was completed in the spring of 1640 (Chongzhen reign, 13th year) and recorded by Chongxu Wu Shouyang, the eighth-generation lineage holder under Patriarch Qiu.

The preface clarifies the book's purpose:

The highest achievement in Daoist cultivation is attaining eternal life, while in Buddhism it is realizing the state of non-birth (transcending the cycle of life and death). However, to achieve non-birth, one must first attain eternal life; and to truly attain eternal life, one must ultimately realize non-birth. This is the principle of "dual cultivation of nature and life (Xingming Shuangxiu)." While the book primarily expounds Daoist practices, it also uses Buddhist principles for verification—hence the title "Unified School," aiming to help future generations understand the importance of dual cultivation. Earlier, The Straightforward Discourse on the True Principles of Celestial Immortals in nine chapters had already detailed Daoist theories. Now, these nine dialogues further reveal the secret methods not explained in the Discourse, as well as the orally transmitted celestial mysteries never before disclosed. With this classic, the most profound principles of cultivation become as clear as the sun, moon, and stars. Those who obtain it should treasure it eternally.

The first chapter, "Initial Return to Emptiness," records the dialogue between Taihe and Chongxu:

Taihe asked: The Straightforward Discourse has already explained in detail the prohibitions during the foundational stage (refining the self) and the consequences of failing to establish this foundation. Yesterday, I also heard that initial foundation-building is merely preparatory guidance, and to truly enter the core of practice, one must "return to emptiness." May I ask what exactly is the principle of "returning to emptiness"?

The Confucian tradition emphasizes the method of "holding the center" (zhizhong), while Daoist immortals cultivate the practice of "returning to emptiness" (huanxu). In truth, the "middle way" is the essence of emptiness itself, and "holding the center" is the practical method for "returning to emptiness." Only those with the innate capacity of immortals or buddhas can thoroughly return to their original nature through this practice, attaining the state of pure unity.

Ordinary people's minds constantly deviate from this empty nature, restless and agitated, drifting through cycles of birth and death without finding liberation. Therefore, to cultivate immortality and attain the Dao, one must first forge a vessel capable of containing the great Dao. To perfect this "Dao-vessel," one must complete the work of returning to emptiness. This "emptiness" refers to the state of Wuji (the Limitless) before the separation of heaven and earth—when there were no mountains and rivers, no distinction between self and others, no insects or plants, and all phenomena were formless and silent. This is our original nature. "Returning to emptiness" means returning to this primordial Wuji and restoring our fundamental nature.

How, then, is this practice accomplished? The key lies in maintaining a mind free of attachment when facing external phenomena. See heaven and earth without clinging to their forms, observe mountains and rivers without lingering on their traces, encounter others without generating distinctions, and interact with insects and plants without being deluded by their appearances. When all phenomena arise before you yet no thought stirs in your mind, and when the six roots (eyes, ears, nose, tongue, body, and intellect) remain undisturbed and untainted—this is the complete return to original nature. In this state of emptiness, past, present, and future thoughts are all ungraspable, and one awakens instantly to the highest teaching. Why then practice gradual cultivation? As the Buddhists say, "In the formless light, there is constant freedom," and "When not a single thought arises, the whole reality appears; when the six roots stir, clouds obscure it." This is precisely the principle.

Regarding "turning the gaze inward" (fan’guan neizhao): This is the wondrous function of "true intent" (zhenyi). The original spirit (yuanshen, innate consciousness) abides unmoving as its essence, while true intent (zhenyi, innate awareness) resonates with all things as its function. The original spirit and true intent are fundamentally one—whether called "spirit" or "true intent" makes no difference. True intent is the correct awareness arising from emptiness; that subtle perception is the act of turning inward—withdrawing the outwardly scattered mind to illuminate the inner self.

This scripture elucidates the essential method of "true intention observation" in Neidan (internal alchemy) practice. In essence:

The three stages of cultivating Jing (essence), Qi (vital energy), and Shen (spirit) all require focused awareness through true intention: refining Jing demands one hundred days of observation, transforming Qi requires ten months, and sublimating Shen takes three years.

The practice involves four key phases:

1. During the active phase (gathering essence-energy), coordinate breathing to unite Shen and Qi

2. In the resting phase (sealing and nurturing), suspend breathing to stabilize Shen-Qi

3. When initiating practice (beginning refinement), kindle the fire at the midnight hour (Zi time)

4. Upon completion (concluding a stage), return to emptiness and cease the fire

The application of true intention manifests in two modes:

1. Dynamic-quiescent interplay: In early Jing refinement, gathering essence represents movement while sealed nurturing embodies stillness; during the later three-year "nursing" phase, the emergence and withdrawal of Shen-Qi constitute movement while returning to emptiness signifies stillness

2. Pure quiescence: During the intermediate Qi transformation stage, maintain unwavering mental focus in the Dantian's (energy center) empty realm without deliberately tracking Qi movements along the Governing and Conception vessels

The scripture specifically warns: improper use of true intention leads to cultivation deviations. For instance, incorrect intention during Jing refinement jeopardizes subsequent practice. Throughout the entire process, appropriate application of true intention—balancing movement and stillness—is essential to align with the profound mechanics of alchemical cultivation.

The Nine Chapters on the Alchemical Dao by Master Wu primarily discusses the importance of "true intention" (zhenyi) in Neidan (internal alchemy) practice, as well as the distinction between "true elixir" (zhendan) and "illusory elixir" (huandan), which hinges on the purity or turbidity of the "water source" (shuiyuan). Here’s a modern interpretation:

If true intention—the pure, undistracted state of mind—is lost during cultivation, it becomes impossible to guide the Yin and Yang energies back to the Dantian (the lower energy center in Daoist practice), making it difficult to harness the subtle workings of Yang energy. Without true intention during the Qi-refining stage, one cannot protect the primordial energy and return it to fetal breathing (taixi). Similarly, during the Shen-refining stage, the loss of true intention prevents the spirit (shen) from stabilizing in the Niwan Palace (the upper Dantian), let alone completing the "nursing" (rubu) process of refining the spirit.

A poem in the text summarizes the cultivation process:

When Yang energy arises, it feels like awakening from a deep dream;

Desires are subdued and gathered into the golden cauldron (Dantian).

Three hundred celestial cycles are completed,

As the four seasons of breath harmonize into stillness.

After seven days, Yang energy revives;

The Five Dragons (energies of the five organs) lift it to the crown.

Ten months of refinement nurture the spiritual embryo,

And three years of practice allow the spirit to leave the body.

All these stages rely on true intention as the guiding principle;

Nine years of cultivation reveal the wondrous realm of true emptiness.

Crucially, true intention must not involve deliberate thought—the moment one forces it, its authentic nature is lost. As the Buddhists say, "To think about it is already a mistake."

Regarding the distinction between "clear and turbid water sources" and true versus illusory elixirs:

A state of scattered thoughts and heightened sensory perception belongs to the turbid, post-heavenly source. Even if refined, the Jing (essence) produced in this state cannot form a true elixir. Only when the mind is free of thought and reaches a state of utmost stillness—the clear, pre-heavenly source—can the Jing, combined with proper cultivation methods, yield a true elixir. In short, the mental state (clarity or turbidity) during practice directly determines whether the results are genuine or illusory.

This passage emphasizes the need to grasp the "intention without intention" (wuyi zhi yi) of true intention while refining essence in a state of inner purity. Otherwise, one risks straying onto the wrong path.

The Nine Chapters on the Alchemical Dao by Master Wu elucidates crucial points regarding "fire timing" (huohou) in Neidan (internal alchemy) practice:

When cultivating, if Yang energy arises from turbid sources, such energy should be discarded. The truly refined method begins from the primordial state of emptiness (xu) — only the Yang energy gathered this way can forge the authentic elixir, avoiding the formation of illusory false elixirs. The ancients taught that refining medicine first requires refining the heart, emphasizing mental purity during practice. Buddhists similarly warn that an impure mind obstructs the seed of bodhi (awakening), reflecting the same principle.

Criteria for determining "sufficient fire timing":

1. Internal standard: Completion of 300 full microcosmic orbit cycles. Two scenarios exist:

• Proper practice: Maintaining mental clarity, collecting medicinal energy (caiyao) and sealing (fenggu) according to method, with undistracted spirit and completed 300-breath cycles — only such orbits count as valid.
• Improper practice: Mental distraction or operational errors causing discontinuous qi flow and spirit-energy separation invalidate the cycles.

Only after accumulating 300 valid cycles is the fire timing deemed sufficient to cease firing.

2. External signs:

• Genital retraction (termed "horse-yin hidden form" in Buddhist texts)
• Illumination at the Mingtang acupoint between eyebrows (Buddhist "radiance shaking the earth" refers precisely to this forehead light)

These constitute definitive signals to terminate firing. Buddhist phrases like "overturning the temple gate's flagpole" and "achieving the Tathagata's horse-yin hidden form" all describe these physiological transformations during cultivation.

This scripture describes the "Three Appearances of Yang Light" phenomenon in Daoist Neidan (internal alchemy) practice:

When cultivation reaches a certain stage, three distinct manifestations of yang light will appear. During the first appearance, practitioners suddenly perceive flashes of lightning before their eyes, illuminating the entire chamber with brightness. At this stage, the "fire timing" (cultivation energy) remains insufficient, requiring continued microcosmic orbit circulation until completing three hundred full cycles.

Upon completing these cycles, practitioners should enter meditative stillness to nurture true yang (primordial qi) while awaiting the second appearance of yang light. This manifests as renewed flashes of lightning between the eyebrows, whitening the chamber's interior—a clear sign to cease applying the "fire" technique. Externally, this stage produces the "turtle withdrawing" phenomenon (complete retraction of male genitalia).

When the third yang light appears, though qi (energy) fluctuations persist internally, practitioners must completely stop applying fire and enter deeper stillness. The third appearance of inter-eyebrow lightning confirms yang qi has fully stabilized at the qi root (lower Dantian).

The scripture specifically warns: after the second yang light appears, despite ongoing qi movements, practitioners must absolutely refrain from further gathering and refining, as this poses serious danger. Only upon witnessing the third yang light manifestation—indicating successful cultivation—may practitioners advance to the next stage. Throughout this process, the three signs (completed microcosmic cycles, turtle withdrawal, and triple yang light) appear sequentially, serving as crucial markers for assessing cultivation progress.

This passage explains the crucial steps and precautions for "gathering the great medicine" (cai da yao) in Daoist Neidan (internal alchemy) practice, containing several key points:

When a practitioner's Yang Qi accumulates to a certain degree, they will experience the phenomenon of "three manifestations of sunlight" (yang guang san xian) - three distinct experiences of luminous perception. During the first and second manifestations, one should begin "stilling the fire" (zhi huo, ceasing active guidance of internal Qi), and completely stop by the third manifestation. These three luminous appearances all serve as markers for fire-stilling.

Particular attention must be paid to the third manifestation, which not only signals fire-stilling but also indicates the proper timing to begin "gathering the great medicine" (collecting the pure Yang Qi within the body). If one fails to stop at this point according to method and continues circulating the fire, causing a fourth luminous appearance, the painstakingly accumulated pure Yang Qi will dissipate outward, transforming into postnatal substantial essence (jing), rendering all previous efforts void. This resembles the Buddhist principle that "the Tathagata wisely guards the precious pearl, naturally emitting light with restraint."

Regarding why the great medicine must be gathered within seven days: when the three manifestations of sunlight appear, the pure Yang Qi has already condensed in the Dantian (elixir field/cauldron), yet remains concealed. Only through seven days of specialized gathering practice can the "fiery pearl" (huo zhu) take form within the Dantian. At this stage, the Qi circulates only internally without external dispersion, hence called "true lead internal medicine" (zhen qian nei yao), also known as "golden liquid returned elixir" (jin ye huan dan) or "great golden elixir medicine" (jin dan da yao).

The specific method for gathering the medicine: initially, breathing should flow naturally - neither forcibly guiding the fire phases nor completely letting it go unchecked. Enter a state of tranquil concentration, focusing intently with the light of the eyes' Shen (spirit) (not physical vision). During daytime, concentrate the dual eyes' spiritual light on the middle Dantian position, maintaining this focused attention unwaveringly at night as well. This embodies the principle stated in the Yin Fu Jing (Scripture of the Hidden Accord) that "the mechanism lies in the eyes" (ji zai mu).

The great medicine's production follows four fundamental principles, including through Yin-Yang interaction and Qi induction. This passage particularly emphasizes seizing the right timing in practice, heeding the signals of the "three manifestations of sunlight," and properly stilling the fire to gather the medicine at the correct moment, thereby successfully consolidating the golden elixir.

This scripture elucidates the four crucial stages of "generating vitality through stillness" in Neidan (internal alchemy) practice:

The first principle describes "conception through coupling": When the formless fire of the heart-mind (original spirit, or Shen) is concentrated in the upper Dantian (energy center) through focused vision, the formless water Qi (original energy, or Yuanqi) from the kidneys naturally rises to merge with it. Like the cosmic intercourse of Yin and Yang that generates all things, this fusion of intangible energies ultimately crystallizes into the Great Medicine of pure Yang (the embryonic form of the internal elixir) in the lower Dantian.

The second principle explains "manifestation through guidance": The divine light of both eyes carries true intention (symbolized as the Yellow Matron, representing the spleen-earth energy of the central palace). Through the directing power of vision—acting like a matchmaker—this facilitates the spontaneous emergence of the Great Medicine. This is the meaning behind the ancient saying "The fetal breath in the central palace is called the Yellow Matron."

The third principle reveals "generation through stillness": When the original spirit becomes stabilized in the upper Dantian through focused concentration, the original Qi naturally settles in the lower Dantian. As both enter this stable state, the Qi spontaneously activates within extreme stillness, embodying the classical teaching "gathering true lead within absolute stillness."

The fourth principle details "creation through settled breath": After the primordial spirit-Qi stabilizes, the postnatal breathing fire also quiets and returns to its root in the Qi foundation (the Dantian). Only when respiration truly stabilizes does the Great Medicine emerge. This is the essence of "gathering true lead through settled breath."

This method, transmitted by Patriarch Qiu Chuji (founder of the Longmen lineage of Quanzhen Daoism), particularly emphasizes using the eyes' power to summon energy. All four stages demonstrate that the "generative vitality" produced through ocular concentration constitutes the core mechanism of internal alchemy cultivation.

The Nine Chapters on the Alchemical Dao by Master Wu describes the crucial process and phenomena in cultivating the Golden Elixir (the core energy of Daoist Neidan practice).

The verse states that the Golden Elixir is not difficult to attain—it manifests in the middle Dantian (the heart region) during daytime and can be preserved through nocturnal stillness. When water (kidney energy) and fire (heart energy) naturally merge without distinction of upper or lower, vital force concentrates between the eyes. This verse reveals that when the Great Medicine emerges, practitioners first experience vibrations of the six senses (eyes, ears, nose, tongue, body, and mind): the Dantian grows hot as if scorched by fire, both kidneys boil like water, golden light flashes in the eyes, wind seems to rise behind the ears, bird calls seem to echo at the back of the head, the whole body surges with energy, and the nose twitches involuntarily. These are all signs of obtaining the Medicine.

Typically, during the third or fourth day of "gathering the Medicine" (collecting Jing-Qi within the body), these signs appear sequentially in a state between stability and instability. If cultivation continues for five or six days until mental focus becomes completely settled, the Great Medicine is produced. Thus, the saying "the elixir completes in seven days" is merely a general expression, akin to the Buddhist descriptions of "celestial maidens offering flowers" or "dragon maidens presenting pearls."

Regarding the mystery of the Great Medicine passing through the Three Barriers (along the Governing Vessel): the metaphor of "Five Dragons Upholding the Sage" (where five represents the spleen-earth symbolizing true breath; dragons represent the Shen-spirit; and the sage denotes the Great Medicine) illustrates using true intention to guide the Medicine through the barriers. Two types of practitioners are mentioned: those with intact primordial essence (who've never lost Jing) and those who've only leaked essence once may use supplementary methods, while those with significant essence loss must employ the orthodox method directly.

When the Great Medicine first emerges, it takes the form of a fiery pearl—this is the pure Yang Qi of primordial origin that generates the postnatal true breath-fire. Since Medicine and fire share the same root, mentioning the Medicine inherently includes the fire. The Great Medicine doesn't manifest externally upon generation but moves solely within the body's Qi cavity (lower Dantian). Special attention should be paid to the four pathways beneath this cavity near the coccyx, as they are crucial channels for Jing-Qi circulation.

This scripture elucidates the crucial methods for preventing the leakage of Jing (essence) and Qi (vital energy) during Neidan (internal alchemy) practice.

It first explains several key energy gateways in the human body: the heart region (located at the solar plexus) connects anteriorly to the Yang Pass (Huiyin point at the perineum), posteriorly to the Tailbone Gate (coccyx), and inferiorly to the Valley Passage (anus). The three apertures of the Tailbone Gate are filled with marrow substance, blocking energy flow, while the Valley Passage remains hollow and unobstructed, serving as the familiar pathway for energy and fluid circulation. This structural contrast between the solid Tailbone Gate and hollow Valley Passage forms what's called the "Lower Magpie Bridge" - the channel connecting the upper and lower Dantian (energy centers).

Moving upward, the three energy gates from Tailbone Pass to Jiaji (mid-back) and Yuzhen (occipital bone), along with the Yintang point (third eye region) between the eyebrows, are all marrow-filled and energy-impermeable. Only the two nasal passages below remain open as breathing channels. This configuration between the sealed Yintang and open nasal cavities constitutes the "Upper Magpie Bridge."

When the Great Medicine (refined Jing-Qi) is about to form, six physiological reactions (in the eyes, ears, nose, tongue, body, and mind) will manifest. Practitioners must maintain sixfold containment:

1. Using a wooden seat to press against the Valley Passage below

2. Sealing nostrils with wooden clamps

3. Closing the eyes to block visual stimuli

4. Concentrating the Shen (spirit) to ignore sounds

5. Keeping lips closed with the tongue touching the palate

6. Maintaining mental purity free from external distractions

Even with such precautions, dangers persist during the internal circulation of the formed Great Medicine. When Jing-Qi emerges from the Qi cavity (Dantian), it may surge upward to the heart region - instability here causes downward collapse. If the Yang Pass is closed, energy diverts to the Tailbone Gate; if blocked there, it rushes toward the Valley Passage. Since the Valley Passage opens easily, any leakage here nullifies previous efforts. This peril at the Lower Magpie Bridge famously caused cultivation failures for both Qiu Chuji and Master Cao.

Preventive measures include: preparing a cotton-padded, bun-shaped wooden seat to support and lift the Valley Passage (external reinforcement), combined with internal reinforcement through focused mind control.

This scripture describes the crucial process of the "Great Medicine" (the condensed energy of vital essence and Qi within the body) circulating through the Governing Vessel (the spinal channel) during Neidan (internal alchemy) practice:

When the Great Medicine energy reaches the coccyx (the lowest point of the spine), there is a risk of downward leakage if it cannot pass through. At this stage, one should gently contract the anus to prevent leakage while maintaining internal stability. Avoid forceful mental guidance—instead, keep the Shen (spirit) tranquil and wait for the Great Medicine to activate spontaneously. Only when you feel it beginning to surge upward naturally should you guide it with the subtlest intention.

The Great Medicine passes through three critical barriers in sequence:

1. Tailbone Pass (Weilü Guan): When encountering initial resistance, maintain quiet observation. After it breaks through spontaneously, gently guide it upward to the Spine Pass (Jiaji Guan).

2. Spine Pass (Jiaji Guan): Again, preserve stillness and stability. When the energy activates on its own, direct it toward the Jade Pillow Pass (Yuzhen Guan).

3. Jade Pillow Pass (Yuzhen Guan): Remain calm until the energy naturally surges through, then guide it lightly to the Crown Point (Baihui), located at the top of the head.

Upon reaching the Hall of Impression (Yintang, between the eyebrows), the Great Medicine may face obstruction and risk leaking through the nasal passages. Here, a wooden clamp (an auxiliary tool) should be used to gently pinch the nose to prevent leakage. Maintain mental serenity, and once the Great Medicine breaks through spontaneously, guide it softly through the Twelve-Storied Tower (throat region) before finally descending into the Middle Dantian (heart center). This completes the vital process of Yin-Yang union and the transformation of the Yin-spirit.

The entire process emphasizes the principle of "non-forced guidance"—one must wait for the energy to activate naturally before assisting its movement, akin to a harmonious dance partnership. At each barrier, measures to prevent leakage are essential, as this determines the success or failure of the cultivation practice.

This passage explains the crucial stages of "passing the barriers and ingesting the elixir" (guoguan fushi) and "refining Qi into spirit" (lianqi huashen) in Daoist Neidan (internal alchemy) practice:

Regarding "passing the barriers and ingesting the elixir" (referring to the process of genuine Qi traversing the three gates along the Governing Vessel):

Master Wu cites Patriarch Qiu's verse stating that when the Golden Elixir (jindan) energy ascends to the crown, simply maintaining focused awareness and purity of the six senses (eyes, ears, nose, tongue, body, and mind free from external distractions) allows natural circulation like the movement of the Celestial Pivot (Tiangang, the handle of the Big Dipper). Here the Celestial Pivot symbolizes the body's "Heavenly Heart" (tianxin, corresponding to the Niwan Palace at the crown's Baihui point area). During practice, the Great Medicine (da yao, concentrated essence-energy) is guided by true intention (zhenyi, pure undistracted consciousness) in its ascent and descent, mirroring celestial bodies orbiting the Heavenly Heart. Practically, a wooden seat may be used to press against the perineum to prevent energy leakage, but if energy naturally remains contained, forceful contraction is unnecessary—the key lies in following natural principles.

Concerning "refining Qi into spirit" (transforming vital energy into higher spiritual consciousness):

After obtaining the Golden Elixir's Great Medicine, it must be circulated through the "River Chariot" (heche, microcosmic orbit) to the "spirit chamber" (shinshi, upper Dantian). Lack of mental focus at this stage causes the Great Medicine to dissipate. The original spirit (yuanshen, primordial nature) and Great Medicine must become interdependent: the spirit provides a foundation for the medicine, while the medicine illuminates the spirit. In the state of "silent illumination" (jizhao, tranquil observation), yang energy spontaneously arises and circulates with true breath (zhenxi, prenatal respiration) within the spirit chamber, thereby refining the spirit. This manifests as the Great Medicine dissolving the yin-spirit (postnatal scattered thoughts) while strengthening the yang-spirit (primordial wisdom-light), eliminating mental dullness and distraction—the essential process of "refining Qi into spirit."

The text further clarifies Dantian locations: the Qi cavity (qixue) resides in the lower Dantian (three inches below the navel, at the Qihai point), while the Yellow Court (huangting, middle Dantian) surrounds the Danzhong point. During practice, the Great Medicine ascends from the lower to middle Dantian to form the "embryo" (internal elixir).

In the practice of forming the Golden Elixir (Neidan terminology referring to the condensation of Jing, Qi, and Shen into a "pill"), two key areas are crucial: the middle Dantian (the region of the Shanzhong point) and the lower Dantian (three inches below the navel). When initially circulating the Grand Heavenly Cycle (an advanced Qi circulation), though the primordial spirit (Shen) primarily resides in the middle Dantian, it must harmonize with the Qi movement of the lower Dantian. The essential point is to allow the Shen to quietly observe these two regions, gradually merging them into a state of emptiness (Xu). By utilizing the Qi dynamics of both areas to assist the Shen in forming the elixir, both Dantians must be attended to. Fixating rigidly on just one area will obstruct the integrated wisdom of spiritual awareness.

The principle of "guarding the center" (a core cultivation method) does not mean rigidly focusing on the physical center of the body but maintaining a state of emptiness. "Guarding" is not forced retention but a natural abiding in stillness and emptiness. The specific method involves neither fixating entirely on the two Dantians nor neglecting them—instead, the Shen calmly observes, allowing both regions to naturally dissolve into emptiness. While maintaining this state, one must achieve the following:

• In stillness, no thoughts arise; even when cultivation reaches the point where breathing ceases and all drowsiness disappears, one remains inseparable from silence.
• In activity, awareness remains lucid, transcending sensory constraints, until Qi movement halts and thoughts extinguish—yet observation never departs.

This unity of stillness and movement, where silence and awareness are inseparable, is the key to the "Ten-Month Fetal Nourishment" (the prolonged refinement of the internal elixir).

Regarding the distinctions between the "fetus," "fetal breathing," and "true fetal breathing":

• During the "Ten-Month Barrier" (a long-term cultivation phase), the Shen's silent observation guiding Qi movement is called the "fetus."
• The circulation of Qi nourishing the Shen is termed "fetal breathing."
• Only when all traces of Qi movement are forgotten, and the Shen returns to profound stillness (deep meditation), does it become "true fetal breathing."

Detailed explanation of the Grand Heavenly Cycle's "fire timing" (cultivation rhythm):

After ingesting the "Great Medicine" (advanced energy), once the Three Passes and Nine Orifices (key meridian nodes) are fully open, Qi thereafter arises and circulates naturally, flowing through the cleared channels to nourish the empty states of both Dantians and cultivate the Shen. At this stage, the ascent and descent of Qi occur entirely spontaneously, requiring no artificial guidance. Since no intentional effort is needed to regulate the fire timing, one must avoid forcibly controlling it, lest it disrupt the Shen's natural transformation.

This passage explains the key points of practicing the "Grand Celestial Cycle" (Dazhoutian) fire timing (a technical term referring to the specific state of Qi circulation in Neidan/internal alchemy practice). To attain the "Great Stability" (Dading) state—a profound meditative absorption—the practitioner must maintain a subtle balance: neither fixating on fire timing nor completely abandoning it.

The cultivation process unfolds as follows: During the initial three months of meditation, while maintaining stillness, the movements of Yin-Yang energies (Yuanqi, primordial Qi) within the body remain faint, manifesting as subtle activity primarily around the navel area. By the fourth or fifth month, through the tranquil observation of primordial spirit (Yuanshen, innate consciousness), turbid Qi gradually dissipates, leading to deeper absorption. At this stage, the primordial spirit becomes nourished by primordial Qi—remaining lucid without dullness—and realizes the state of "True Emptiness" (Zhenkong).

Between the sixth and seventh months, not only are distracting thoughts completely absent, but even the sensation of drowsiness vanishes entirely. By the eighth or ninth month, the stillness deepens further as all meridians throughout the body settle into perfect calm. Persisting through the full ten-month period culminates in attaining pure Yang state, where the primordial spirit achieves complete stability. This brings forth six spiritual penetrations: 1) the penetration of ending outflows (liberation from afflictions), 2) divine sight, 3) divine hearing, 4) knowledge of past lives, 5) understanding others' thoughts, and 6) mastery over spiritual realms.

A crucial warning: The penetration of spiritual realms particularly risks triggering attachment (the mischief of acquired consciousness/Shenshi). Becoming engrossed in foreseeing the future or discussing fortunes and misfortunes may instead invite calamity. Authentic practice requires maintaining wisdom without misuse—transforming ordinary cognition into true wisdom—to ultimately accomplish "Fetal Completion" (Taiyuan, the supreme achievement in internal alchemy).

The annotation mentions "Mao-You-Zi-Wu" referring to four crucial daily periods (Mao 5-7am, You 5-7pm, Zi 11pm-1am, Wu 11am-1pm) requiring "bathing" (adjustment and relaxation). The entire ten-month fetal nurturing process hinges on continuously sustaining the work of serene observation and absorption.

This passage elucidates the Daoist Neidan (internal alchemy) practices of "bathing" (沐浴) and the state of "embryonic completion and spirit emergence" (胎圆出神). Regarding the practice of "bathing":

In cultivation, "bathing" refers not only to the resting phase during the metaphorical "ten-month gestation period" of practice, but more crucially serves as a safeguard against potential dangers. Each of the Five Phases (Wood, Fire, Earth, Metal, Water) has its own cycles of growth, bathing (rest), and decline. For instance, the Fire phase grows during the Yin hour (3-5am), bathes during the Mao hour (5-7am), and declines during the You hour (5-7pm). Similarly, the Water and Earth phases grow during the Shen hour (3-5pm), bathe during the You hour, and decline during the Mao hour. These transitional hours (Mao, You, Zi, Wu) represent both opportunities for restorative bathing and potential stagnation points.

Authentic "bathing" practice encompasses three dimensions: Primarily, it involves cleansing mental distractions; at its core, it maintains the balance of Yin-Yang Qi (primordial energy) within the body; and at its deepest level, it purifies body and mind through the steaming process of genuine Qi. Without proper mental purification, one cannot achieve the balanced circulation of energies or the transformative steaming effect. Thus, true "bathing" is essentially achieved through sustained, focused cultivation.

Concerning the state of "embryonic completion and spirit emergence":

Months before reaching embryonic completion (maturation of the inner elixir), practitioners may experience near cessation of breath and pulse. Whether during or beyond the "ten-month barrier" (primary cultivation period), any lingering mental dullness or distraction indicates incomplete purification of Yin energies and impure Shen (spirit). Only when all mental turbidity and distraction are completely absent can one achieve the pure Yang embryonic spirit and enter the immortal realm. This process corresponds to the four stages of Buddhist meditation (initial concentration, breath cessation, pulse cessation, and complete stillness).

Regarding spirit emergence cultivation:

When Neidan practice reaches complete spiritual purity and perfect embryonic completion, the Yang spirit must no longer dwell in the middle or lower Dantian (energy centers in the chest and abdomen). Practitioners must employ the "transfer method" to move the Yang spirit to the upper Dantian (Niwan Palace at the crown of the head). At this stage, the Yang spirit remains as delicate as a newborn infant, requiring tender "nursing" care—hence the term "nursing" practice. This phase typically requires three years of careful nurturing, during which one must avoid prematurely confining the Yang spirit within the limited realm of the upper Dantian.

This passage explains the Daoist practice of "nourishing the yang spirit" (the nurturing stage after the initial formation of the yang spirit) and its key considerations. The main points are:

During cultivation, one must maintain mental stillness—neither forcibly focusing on the upper dantian (the head's energy center) nor neglecting it entirely. Instead, allow the yang spirit to naturally settle in the upper dantian, merging with the void. This is the primary task of the nurturing stage. When cultivation reaches a certain level, signs of "spirit excursion" (the yang spirit temporarily leaving the body) may appear. At this point, the yang spirit should be allowed to venture out but must be promptly recalled.

Spirit excursions should progress gradually: initially venturing only a short distance before returning, then slowly extending further—never rushing the process. Like an infant, the yang spirit is prone to becoming lost and may encounter interference from celestial demons (illusory trials in cultivation). Thus, utmost caution is required. As the ancients said, "For every foot the Dao rises, demons rise ten feet." Practitioners must guard against both external demons and internal distractions.

The foundation lies in perfecting the practice of "returning to the void" (reintegrating with the formless realm). If one can fully merge with the void from the outset, maintaining a mind pure and untainted, demonic obstructions will naturally dissipate. Only after three years of careful nurturing can the yang spirit mature, attaining the unimpeded freedom to traverse realms. This parallels the Buddhist concepts of "attaining perfect enlightenment" and "becoming a Buddha's child."

Ultimately, the passage emphasizes that the root of cultivation lies in reaching the supreme state of "returning to the void."

Someone asked: The Direct Discourse mentions "nine years of wall-facing" and "returning to emptiness" in the final stage of cultivation, but the exact meaning of "refining the spirit" remains unclear. Could the master elaborate?

The master replied: What we call refining the spirit (Lianshen) actually reaches the stage where "deliberate concentration is no longer needed." During the phases of "guarding the center" (an intermediate Neidan stage) and "nursing the infant" (a Neidan term referring to the nurturing stage of spirit-Qi fusion), one still needed to maintain conscious stillness and observation. But at this ultimate stage, consciousness operates spontaneously, returning to the Wuji origin (the Daoist ultimate source) and merging with the void. This state requires prolonged cultivation to perfect one's nature—far more than just nine years. The "nine years" reference simply helps newly realized immortals understand that returning to emptiness is the prerequisite for becoming celestial immortals (Tianxian).

During these nine years, practitioners neither perceive the Great Dao they're cultivating nor the immortal/Buddha realms they're realizing. Mind and method completely dissolve into naturalness—so still that even the concept of stillness disappears, so observant that even the thought of observation vanishes. Why then would we need to deliberately speak of "spirit"? The term "returning to emptiness" is merely a provisional designation for this practice. As Buddhism also states: "To realize the void-nature, be equal to the void itself; when truly realizing the void, neither 'is' nor 'isn't' remains." Our Daoist essence resonates with this truth.

[Postscript]

When the Collected Sayings on Immortals and Buddhas was first completed, Suzhou disciple Wu Chengchuan asked whether it should be published. Chongxuzi (the Daoist name of Wu Shouyang) replied: Absolutely not. This text records the oral instructions and celestial secrets of the Dragon Gate lineage, continuing the dharma transmission of Patriarch Qiu (Qiu Chuji, founder of the Longmen branch of Quanzhen). It should only be taught to three types of people: first, those who have completed the "hundred-day foundation" (basic Neidan training); second, families with three generations of virtue who can support the master's cultivation; third, those without means who can assist in fundraising. This embodies the ancient principle of "dharma and resources aiding each other"—requiring both spiritual affinity and material support.

[Patriarch Qiu's Secret Zhou Tian Verse]

(These verses describe the crucial fire-phases in Neidan practice:)

When stillness reaches its peak, Yang energy naturally stirs (the return of primal Yang). As the "medicine" (condensed essence-Qi-spirit energy) emerges, the original spirit (Yuanshen) intuitively knows—this is the spiritual secret. The nascent Yang remains fragile initially; don't hastily gather it. Wait until the medicine solidifies like the full moon on the fifteenth day, then harvest without delay. Procrastination makes the medicine spoil. When Qi scatters outward, the spirit follows; when the spirit returns to the Dantian, Qi naturally roots. Seal the gathered medicine between breaths—not too late, not too soon. The Zi hour (11pm-1am, Yang's birth) begins the fire-phase... (Specific fire-phase techniques omitted hereafter)

This scripture explains the method of applying "fire timing" (huohou) in Daoist Neidan (internal alchemy) practice, specifically the cultivation techniques involving the coordination of breath and intention.

The text states that during cultivation, one must master the rising and descending rhythm of the breath, while the fire timing (the control of intention during practice) should be subtle—neither too strong nor absent. When refining within the Dantian (the "cauldron of fire"), the breath should be natural yet effective. A true practitioner must grasp the proper timing of fire application, counting breaths (ke lou) to measure time and determine the appropriate cultivation periods.

The specific method is as follows: From the Zi hour (midnight) to the Si hour (late morning), these six Yang hours employ the "nine revolutions" method, totaling thirty-six breaths, to gather Jing (essence) and Qi (vital energy) for ascension. From the Wu hour (noon) to the Hai hour (late night), these six Yin hours use the "six revolutions" method, totaling twenty-four breaths, to refine and descend. During the Mao hour (early morning), when Yang Qi is at its peak, one should "bathe" (rest and adjust), reducing the Yang fire. Similarly, during the You hour (evening), when Yin Qi is strong, one should also "bathe," halting the Yin methods (Yin fu). During these bathing periods, there is neither ascension nor descent—a state somewhat resembling the phenomena observed in Grand Celestial Cycle (Da Zhoutian) practice.

A complete Celestial Cycle consists of three hundred breaths, excluding the bathing periods of Mao and You. If the bathing periods are included, it totals three hundred and sixty breaths. Adding five du (approximately a quarter-breath) symbolizes the "intercalary surplus" (extra time), completing the cycle before returning to a state of quiet cultivation. At this point, the mind should concentrate on the Qi cavity (Dantian), awaiting the resurgence of Yang Qi.

With prolonged practice, Jing (essence) will transform into Qi (higher-level energy). When one perceives the "returning wind" (internal Qi movement), it is time to stop—persisting in this way for a hundred days will yield results. If the "six roots tremble" (six sensory faculties manifest unusual reactions), one should proceed according to the "seven-day oral formula" (a specialized method). To advance to Grand Celestial Cycle cultivation, one must seek further instruction in more profound techniques.
