《純陽三書》Vol. 9

Heaven, Earth, and Humanity stand as the Three Powers, yet comprehending their fundamental principle is paramount. Within the human body resides an innate spiritual luminosity (lingming) capable of illuminating the void. To truly recognize and firmly grasp the existence of the Primordial True Qi (the foundational energy of life), the key lies in steadfastly upholding the cosmic law within one's heart.

Though methods for cultivating inner nature (xinggong) are numerous, their essence invariably revolves around the Primordial Nature—pure True Qi itself, concealed within the body's form and breath. Yet obscured by physical form and postnatal breath, compounded by the delusional thoughts (yi mo) of consciousness, depleted by the Six Desires (of eyes, ears, nose, tongue, body, and mind), and disturbed by the Seven Emotions (joy, anger, sorrow, fear, love, hate, and desire), the originally complete Primordial Qi (the pure Yang energy represented by the Qian trigram in the Bagua) gradually dissipates. As years pass, Yang energy exhausts leaving only Yin, until the Primordial True Qi vanishes completely—whereupon form and breath shall perish accordingly.

This Primordial Nature exists within the human body by virtue of True Qi—this is the cardinal principle. Speaking purely theoretically, Primordial Nature does not refer to concrete Qi. After birth, the physical body engages in various movements—gestures, interactions—all following natural patterns. Those who live peacefully by adhering to these daily patterns embody the principle of innate nature. Yet while Qi governs life and death, principle discerns right from wrong. Though seemingly distinct, principle can only be discussed where Qi exists, and Qi can only be nourished by following principle—thus the agency over life, death, and moral judgment rests within oneself, free from external dominion.

Therefore, if Dao cultivators fail to distinguish right from wrong and act contrary to cosmic principle, the Primordial Qi will naturally dissipate. Once Qi is lost, only death remains without vitality. Hence the foundational practice must begin with discerning principle—examining the right and wrong in all matters, aligning with cosmic law while avoiding its violation. Thus the heart gains mastery: the Six Desires cease arising, the Seven Emotions naturally dissolve, and the Primordial Qi requires no forced retention to be nourished within the Central Yellow (middle Dantian).

The second verse states: The Primordial (cosmic origin) and the Postnatal (material world) must be clearly distinguished, for True Qi (Primordial energy) and ordinary breath (postnatal respiration) differ fundamentally in nature.

The path of cultivation requires understanding the balance between "active practice" (youwei) and "non-action" (wuwei), as these two are interdependent and mutually supportive. Humans are born with innate Qi (referring to the fundamental energy of life)—without this Qi, life cannot exist. Acquired Qi (referring to the breath) arises from life activities, yet without the support of innate Qi, acquired Qi cannot transform or function. Innate Qi sustains acquired Qi, while acquired Qi in turn relies on innate Qi.

After birth, if one's Qi mechanism is exhausted through excessive labor or dissipation, innate Qi will scatter. But if one maintains calm breathing, innate Qi can coalesce. From this, we understand that to subdue innate Qi, one must first regulate acquired Qi—without regulating acquired Qi, innate Qi cannot gather, and acquired Qi will gradually dissipate. Acquired Qi requires active cultivation (youwei), while innate Qi requires natural stillness (wuwei). When acquired Qi is deeply nurtured, the breath becomes calm, and with calm breath, innate Qi is preserved. This illustrates that innate Qi is like the commander-in-chief, while acquired Qi serves as the assisting minister.

Furthermore, acquired Qi is governed by the spirit (shen), which in turn is directed by the mind. When the mind is focused, the spirit does not scatter; when the spirit is stable, the breath remains steady and does not stray, allowing innate Qi to fill the body and circulate endlessly. When the mind is at peace, the restoration of innate Qi is not difficult. In summary, Qi (innate and acquired), spirit, and mind are interconnected like the mechanism of a crossbow: the mind is the one who operates the mechanism, the spirit is the force that moves it, the breath is the bowstring that responds to the mechanism, and innate Qi is the arrow that is ultimately released.

A practitioner must first discern right from wrong to ensure the direction of cultivation is not misguided. With the correct direction, the mind gains mastery, the spirit finds its anchor, and the breath has its foundation. Innate Qi can then gradually return to its original state. When true nature manifests, all desires and distracting thoughts naturally dissolve, revealing a state of pure harmony. Cultivating the body in this way illuminates the Three Realms; refining the Golden Elixir (jindan) in this way leaves the spirit untainted by dust; applying this in transformation yields efficacious results; and accumulating virtue (de) in this way brings blessings for generations. Thus, all efforts in Daoist cultivation begin with refining one's nature, while subduing Qi and nurturing breath serve as the foundational entry points—this principle is clear.

Regarding the relationship between the innate and the acquired, one must carefully discern: they sometimes separate and sometimes merge, yet in essence, they are naturally unified. The key lies in grasping the pivotal "central cavity" (referring to vital acupoints or the core of cultivation). If one becomes attached to distinguishing or forcibly seeking the separation or union of the innate and acquired, they will deviate from the true path. Cultivation should follow nature, neither leaning to one side nor the other.

The distinction between "Qi" (primordial vital energy) and "breath" (postnatal respiratory energy) can generally be understood, but requires more nuanced explanation.

How do primordial Qi and postnatal breath interact yet remain distinct? Though belonging to different realms of existence, both are natural life energies bestowed upon us. Primordial Qi is exquisitely refined, concealed within the body's central axis (the "Yellow Center," referring to the Dantian region), taking root through deep respiration. Though it undergoes subtle transformations of ebb and flow, it never truly dissipates—like an endlessly murmuring stream, supremely tranquil yet vibrantly alive, akin to tree roots buried so deep that even an axe cannot harm them.

Postnatal breath governs the body's kinetic functions, transformed from the essence of food and drink, circulating through the body with each respiration. It can expand or contract, enter or exit, appear or vanish, move or rest—much like soldiers in an army: they act when the commander (primordial Qi) gives orders and stand by when uncommanded. Here we see Qi as the sovereign and breath as the subordinate. Yet a commander without troops cannot manifest authority, just as troops without command remain disorganized—this illustrates why Qi and breath must cooperate.

Why then are they considered distinct? Primordial Qi manifests differently in each person's constitution: some receive heaven's generous endowment, others a meager portion, with further variations of excess or deficiency. These disparities are determined during parental union, resulting in varying postnatal physical endowments. Postnatal breath, however, responds to circumstance: a life of ease or toil nurtures or depletes it. Those living comfortably, eating properly, with tranquil minds see their breath grow abundant daily. Conversely, those frustrated in aspirations, malnourished, physically exhausted, or indulgent in desires will gradually deplete their breath until their form withers and vitality exhausts.

This reveals the simultaneous unity and duality of Qi and breath. Only by grasping both their interconnectedness and separateness can one truly comprehend the subtle distinctions between these two life energies.

This scripture primarily discusses the relationship between "deliberate action" (youwei) and "non-action" (wuwei) in cultivation practice, as well as how to attain the natural state of true nature through breath regulation and Qi nourishment.

In the path of cultivation, deliberate effort and natural non-action may appear contradictory but are actually unified. Within the human body exist two types of Qi: postnatal Qi (the Qi of deliberate action) and prenatal Qi (the Qi of non-action). In the initial stages of practice, one must rely on the regulation of postnatal Qi to nurture prenatal Qi. When prenatal Qi becomes abundant within the body (specifically in the "Yellow Center," referring to the Dantian region), it in turn nourishes postnatal Qi. When the three treasures of Jing (essence), Qi, and Shen (spirit) are sufficient, postnatal Qi naturally becomes plentiful.

Although cultivators ultimately aim for the state of wuwei, they must first employ the deliberate practice of "calming Qi and concentrating Shen" to guide their vital energy. Through persistent meditation, stabilizing Qi in the middle Dantian allows the transition from youwei to wuwei. Upon reaching the wuwei state, when internal Qi becomes abundant, heaven and earth appear clear and bright, the seven emotions and six desires naturally subside, and one's true nature manifests—this is when one becomes a genuine Dao-realized being.

The key to cultivation lies in understanding the cyclical process of "progressing from youwei to wuwei, then generating youwei from wuwei." Through careful contemplation and persistent practice, one can ultimately attain the state of illuminating the mind and perceiving true nature.

The text ultimately emphasizes that all cultivation methods fundamentally revolve around mastering the primordial Qi. Beginners should start from a state of non-attachment, then learn the methods of youwei, until finally achieving the harmonious integration of prenatal and postnatal Qi—this constitutes the essential secret of successful cultivation.

This passage elucidates the principles of self-cultivation. First, one must comprehend the nature of things—when encountering situations, calmly analyze right and wrong, discerning the true principles beneath apparent correctness and the valuable aspects within seeming errors. Upon discovering the most balanced and unchanging truth that aligns with the Middle Way (Zhongzheng zhi Dao), one must resolutely uphold it regardless of gains or losses, life or death, poverty or wealth. Only through such steadfastness can the spirit (Shen) find peace and the vital energy (Qi) return to its source.

Achieving this requires both discerning judgment and unyielding willpower, which together cultivate a state of selfless impartiality. Through daily practice in this manner, one's true nature will naturally manifest, and internal Qi will gather at the Central Yellow Court (Zhonghuang, the Dantian). Unfortunately, most people fail to distinguish right from wrong, relying instead on brute courage to compete for superiority, completely ignorant of the principles of quiet cultivation—like blind men unable to discern direction. Thus, those pursuing spiritual refinement (Xiuzhen) must clearly differentiate heavenly principles from human desires, eliminating selfish cravings to nurture innate nature and return to the true path (Zhengdao). Only then can one genuinely grasp the essence of tranquilizing the Qi.

The subsequent poetic line, "Qi subdued at the Central Yellow also bears merit," means that when internal Qi gathers in the Dantian, it connects heaven and earth. Though one may traverse all directions, the key lies in allowing the primordial spirit (Yuanshen) to dwell peacefully in the central palace (the heart). Once the principle of tranquilizing Qi is understood, the next step is the practice of subduing Qi (Fuqi, restraining internal energy). Innate Qi (Xiantian zhi Qi) originally lies latent in the Central Yellow. Though individuals differ in endowment, this energy flows continuously. If one could preserve primordial Yang (Yuanyang) from being damaged by the seven emotions and six desires after birth, the true Qi would naturally remain stable without deliberate restraint.

Yet, from the moment physical form is acquired, the desires of the eyes, ears, nose, tongue, body, and mind burden the heart-mind (Xinshen), preventing it from settling and causing internal Qi to scatter. From the age of sixteen, primordial Yang begins to deplete—year by year, it diminishes without conscious preservation. Whether through major or minor dissipation, the loss accumulates, which is why so many die prematurely. This is not because heaven denies us longevity, but because we fail to nurture what we have been given.

This scripture primarily explains the methods and principles for cultivating true Qi (primordial vital energy). The author points out that humans do inherit this Qi from their parents, but subsequently dissipate it through their own actions. The key to cultivation lies in gathering and preserving this spark of primordial yang energy without letting it scatter.

The specific practice method involves: using the heart-mind as the guide, employing the spirit (Shen) as the active force, and utilizing breath as the supporting element. It requires daily accumulated effort, following the cyclical patterns of the sun and moon, maintaining a state of purity and wuwei (non-action), while adhering to the principle of unwavering sincerity. Starting from the most basic measure called "one zhu" (an ancient unit of weight), accumulating up to 360 zhu restores complete true yang energy. The ultimate goal is to achieve the state symbolized by the Qian hexagram (representing pure yang) and transform into a body of pure yang.

The text particularly emphasizes that when first cultivating heart-mind nature, one cannot immediately reach this state—progress must be gradual. While the practice appears to involve conscious effort on the surface, it actually follows the principle of wuwei; what seems like non-action secretly contains purposeful action. Postnatal breathing energy is also crucial, hence the author proposes the cultivation method of "harnessing breath to subdue Qi."

The poetic section concisely summarizes the essential teachings: the crux lies in heart-mind and spirit. Through persistent diligent practice, one naturally ascends to the celestial realm (referring to higher spiritual states). The key to concentrating the spirit lies in gathering mental focus—when the mind becomes still, the Qi becomes calm, and when Qi calms, the spirit naturally returns to unity.

Finally, the meaning of "concentrating the spirit" is explained: spirit acts like the commander of Qi and the soldier of the heart-mind, being actually condensed from primordial essence (Jing). The human body consists of three components—essence, Qi and spirit. Spirit originates from essence, and essence derives from Qi. When Qi is abundant, essence becomes full; when essence is full, spirit becomes concentrated. Failure to concentrate the spirit stems from two causes: first, insufficient innate true Qi (like a starving person lacking limb strength), and second, uncontrolled movement of postnatal blood Qi (like an impulsive person lacking self-restraint).

This passage discusses the relationship between Qi (vital energy) and Shen (spirit) in Neidan (internal alchemy) practice. Within the human body, there exist two types of Qi: the innate primordial "Qi" (the foundational life energy in Daoism) and the acquired postnatal "Qi." When primordial Qi is deficient, it affects postnatal Qi; similarly, the inability to concentrate one's spirit stems from this same root cause.

The key to cultivation lies in this: replenishing primordial Qi requires Wuwei (non-action) cultivation (natural practice), while regulating postnatal Qi demands "youwei" methods (active practice). The so-called youwei methods involve refining one's nature through stillness practices, with regulating the spirit being the most essential technique.

When the breath becomes tranquil, one proceeds to "the copulation of water and fire" (a practice method involving the interaction of heart and kidney energies). The practitioner gathers their spiritual intention at the "Court of Two Soils" (referring to the middle Dantian area). By persisting in this daily practice, the spirit gradually concentrates at the "Central Yellow" (the energetic core at the body's center). Through prolonged practice, one attains a state of mental serenity, where primordial true Qi naturally returns to its source and true nature spontaneously manifests. At this stage, one no longer needs deliberate efforts to calm the breath—it becomes tranquil naturally; no conscious concentration is required—the spirit gathers effortlessly. This embodies the principle of "calming Qi to concentrate the spirit, concentrating the spirit to subdue Qi."

The subsequent poetic lines depict the visionary experiences during practice: "Water north and fire south, two Qi take precedence" refers to the interaction between kidney-water and heart-fire energies; "The whole body's movement fills the central heaven" describes true Qi permeating the entire body; "Forming a perfected being to face the Heavenly Emperor" symbolizes the achievement of cultivation; "The harmonious fusion of four images creates graceful movement" portrays the wondrous state of balanced Yin-Yang and the four phases in harmonious operation.

The deeper meaning of water-fire copulation fundamentally relates to blood-Qi circulation, which in turn cannot be separated from the Dao of Yin-Yang. In nature, water (Yin) and fire (Yang) naturally interact without human intervention. However, to attain genuine realization through cultivation, one must master methods of conscious guidance. These guided approaches divide into two types: cultivation that follows natural patterns (the ordinary person's way) and cultivation that reverses conventional order (the immortal's path).

Reverse cultivation further divides into two forms: the minor internal copulation and the major external copulation. The minor copulation involves the ascent of kidney Yang energy to the heart palace and the descent of heart Yin energy to the kidney position—this ascending-descending convergence occurs at the site of central yellow true Qi, which can nurture the primordial single Qi. Although this constitutes postnatal youwei practice, it requires spirit-consciousness as the guide and breath as the support. While the principle advocates "calming Qi to concentrate spirit," the true crux lies in maintaining the subtle state where the spirit dwells between "non-attachment" and "focused attention." In this state, wherever spiritual intention reaches becomes the site where water-fire, Kan-Li unite.

This passage discusses the practice of "water-fire copulation" (shuihuo jiaogou) in Daoist Neidan (internal alchemy), which operates at two levels: minor copulation and major copulation.

The minor copulation involves merging the Wu earth (spleen's yang qi) and Ji earth (spleen's yin qi) in the Yellow Court (middle Dantian), generating the radiant light of true nature. This requires prolonged cultivation until one's true nature spontaneously manifests.

The major copulation represents a more advanced stage where celestial yang (Qian, heaven) and earthly yin (Kun, earth) unite within the body. During practice, qi must circulate through the five organs and penetrate the Three Passes (Weilu, Jiaji, and Yuzhen—three crucial acupoints along the spine), moving back and forth like a turning wheel that mirrors the sun-moon cycles and seasonal transitions. This process dispels yin demons and restores the pure yang body. The authentic qi must permeate the Three Flowers (Jing, Qi, and Shen), flow through the five organs, pass the Storied Tower (trachea), and finally return to the Dantian (earthen cauldron). When qi circulates smoothly, practitioners experience physical ease and mental clarity, as if ascending azure clouds to survey heaven and earth, ultimately reaching the state of self-forgetfulness and unity with the Dao.

Practice must progress step-by-step—major copulation always begins with minor copulation. The specific method involves daily seated meditation, regulating breath while attentively listening to internal sounds. The upper body (head region) requires lifting the perineum to secure qi, while the lower body (Dantian) demands concentrated focus on essence and spirit. Using intention to guide qi, one harmonizes the innate and acquired water-fire energies in the Yellow Court. Initial practice requires deliberate effort, but gradual refinement leads to spontaneous circulation, culminating in an unbroken, continuous state.

The concluding verse emphasizes fire's pivotal role in Five Phases cultivation. Here "fire" refers to heart-fire, which must be subdued and submerged into the ocean floor (lower Dantian), like a hidden dragon reigning supreme in deep waters. This constitutes the crucial "heart-kidney interaction" (xin-shen xiangjiao) in Neidan practice.

This scripture elucidates the Daoist cultivation principle of "subduing fire" (controlling yang qi within the body) and its methods. Fire (yang qi) inherently tends to rise and flare upward, yet during cultivation it must be guided downward. This is because when yang qi reaches its peak intensity (at the end of the noon hour), yin qi naturally begins to emerge within, causing the true nature (one's innate primordial essence) to descend accordingly. Though yang qi descends, its fundamental yang nature remains unchanged, so it will ultimately rise again.

This alternation between yin and yang mirrors the natural order: after noon, yang qi descends, only to rise anew after midnight. Ordinary people, drifting with these currents, remain trapped in the cycle of life and death. Daoist practitioners, however, employ specialized methods to sink yang qi into the dantian (the "ocean floor" energy center), accumulating energy through years of sustained practice. The specific technique involves using the heart-mind (shen) as the commander and focused intention as the vanguard, regulating the "fire times" (energy control during cultivation) through concentrated stillness. With prolonged practice, water and fire harmonize, forming a pure cluster of primordial nature.

The tenth section further explains that the ascent of water (the movement of yin qi) likewise requires the merging of spirit and intention. When the heart-mind fully integrates with both water and fire qi, a state of yin-yang equilibrium in cultivation is achieved. This practice ultimately leads to the Daoist immortal realm—transcending life and death while sharing longevity with heaven and earth.

This passage elucidates the core principle of "water and fire in perfect balance" (水火既济) within Daoist Neidan (internal alchemy) practice. The essence of cultivation lies in regulating the directional flow of water (kidney essence) and fire (heart fire) within the body.

In their natural state, the body's water (seminal essence and Qi) follows a forward cycle: it originates from the kidneys (Kun position), flourishes in the lungs (Dui marsh), weakens upon reaching the heart (Li fire), is nourished by the liver (Zhen wood), and finally returns to the spleen and stomach (central earth). This natural circulation resembles water flowing from southwest to northeast, completing a daily cycle before returning to the kidneys (Kan position), moving according to Qi's rising and descending rhythms.

However, practitioners must master the reverse cycle: elevating kidney essence from below upward, shifting from left to right, ultimately gathering it in the central palace (Dantian). The specific method involves guiding essence-Qi from the feet (Lidui acupoint), passing through Zhongwan point, traversing the three passes (Weilü, Jiaji, and Yuzhen), before concentrating in the Yellow Court (left side of middle Dantian). This reverse cycle enables postnatal water (acquired essence-Qi) to nourish prenatal water (primordial Qi).

When primordial Qi becomes abundant, acquired essence-Qi flourishes in turn; this flourishing then further nourishes primordial Qi. Thus essence never depletes, Qi remains sufficient, and Shen (spirit) becomes full. At this stage, neither heart fire (sovereign fire), life-gate fire (ministerial fire), nor kidney fire (people's fire) will cause internal heat, achieving perfect water-fire equilibrium where the "true person" (internal elixir) naturally crystallizes.

The core of cultivation lies in concentrated Shen: when spirit focuses on the central palace, Qi flows naturally, blood follows Qi, and essence-water springs forth endlessly. Like a fountain bubbling from its source, water rises while fire descends—seemingly separate yet fundamentally united. Practitioners must thoroughly comprehend these dual principles of water-fire movement.

The concluding quatrain reveals: all immortals and sages throughout history have guarded this crucial practice secret, simply because ordinary people cannot maintain steadfast cultivation. With unwavering dedication, one may penetrate its mysteries and behold the Dao's true source. The essential method of nature cultivation (性功) involves nothing beyond concentrated spirit and quieted Qi to subdue wandering thoughts, yet the key lies in mastering this bodily foundation.

The crux of cultivation lies in locating and maintaining the body's most essential cavity (referring to key energetic nodes in neidan practice). This cavity sits precisely at the body's center—neither high nor low, neither left nor right—as expounded in the doctrine of the Central Yellow (Zhonghuang, the Daoist term for the body's core energy hub). Above, it connects with the Qian position (the heavenly trigram in the Bagua system) at the crown; below, it links with the Kun position (the earthly trigram) at the perineum, maintaining perfect equilibrium in all directions.

This cavity resembles a spacious hall where Qi circulates freely. When Shen (consciousness) dwells here peacefully, it's like an emperor presiding over his court, with all internal organs obeying its commands. Its color corresponds to earthen yellow, enveloped by the dual currents of Yin and Yang above and below. Every inhalation and exhalation revolves around this primordial Qi (the foundational life energy in Daoism), which constitutes a person's true vitality.

Physically located near the kidney region, this six-inch-long cavity resembles a lotus root with interconnecting passages at both ends, facilitating Qi circulation. This "Golden City" simultaneously harbors primordial Qi and nurtures postnatal Jing (essence). Every person possesses this cavity—the key lies in recognizing and focusing upon it. When practitioners concentrate their Shen here, primordial Qi will naturally suffuse the entire body from within.

This cavity's significance parallels the golden throne in the Purple Tenuity Palace (the Daoist metaphor for the body's supreme energetic center), determining life and death. Both the Yin spirit and Yang spirit must emerge from here, ascending through the Niwan Palace (the crown energy center) to meet the Jade Emperor and Perfected Ones in celestial realms.

The cultivation essentials can be summarized in four verses:

To subdue the heart's fire (dragon) and kidney's water (tiger),

Balance is needed like two earths forming the medicinal spoon (an alchemical metaphor for harmony).

If unable to self-regulate,

Rely on that spark of primordial divine light.

Practitioners who miss this essential cavity

Drift endlessly like a boat lost at sea,

Never reaching the other shore.

This scripture primarily discusses the relationship between Yin-Yang, Qi-blood, and the dragon-tiger symbolism within the human body, as well as methods to achieve harmony between Yin-Yang and the return of Qi-blood to their primordial state through cultivation.

The human body contains the division of Yin and Yang, symbolized by the dragon and tiger. Yin represents blood, generated by the liver located in the east, corresponding to the Zhen trigram (symbolizing thunder) in the Bagua (Eight Trigrams). Yang represents Qi, generated by the lungs in the west, corresponding to the Dui trigram (symbolizing marsh). The dragon belongs to Yang and symbolizes Qi, while the tiger belongs to Yin and symbolizes blood. The dragon (Qi) tends to ascend, and the tiger (blood) tends to descend. The key to cultivation lies in making the Yang Qi descend and the Yin blood rise, allowing them to mutually constrain each other and achieve balance.

If practitioners fail to harmonize the Azure Dragon (Yang Qi) and White Tiger (Yin blood), it will lead to Yin-Yang imbalance and obstructed Qi-blood flow, making it difficult to condense the "Wu earth" and "Ji earth" (Neidan terminology referring to the refined essence after the union of Yin and Yang), let alone attain the state of pure Yang (the highest realm of cultivation). Only by returning the dragon to the ocean floor (Qi sinking to the Dantian) and subduing the tiger at the western mountain (blood returning to the primordial sea) can the true form of a realized being manifest in Neidan (internal alchemy) practice, achieving the immortal state where Yang Shen (spirit) and Yin Shen unite.

The text then emphasizes the importance of the "heart." The heart governs the body like an emperor ruling over all. However, the heart is often disturbed by desires and selfish thoughts, fluctuating between movement and stillness, plagued by distractions. If the heart can maintain its fundamental nature, it can sever the six desires (of the eyes, ears, nose, tongue, body, and mind) and eliminate the seven emotions (joy, anger, sorrow, contemplation, grief, fear, and shock), preventing the senses from being tempted by external objects and attaining a state of purity and Wuwei (non-action). The key to cultivation lies in observing the inner heart to discover the "true seed" (original heart or primordial Qi), which is the fundamental method for cultivating one's nature.

This scripture primarily explains how to cultivate body and mind by regulating the six desires and seven emotions, while emphasizing the vital importance of kidney essence (Jing) and Qi.

The text first describes the need to control six types of sensory desires during practice: the nose shouldn't crave smells, the mouth must avoid idle speech, the tongue shouldn't indulge tastes, and thoughts must remain free from fixation. Seven emotions should also be moderated - joy without excess, anger without harm, measured sorrow, tempered fear, love without obsession, dislike without prejudice, and restrained desire. When neither the six desires nor seven emotions disturb the Shen (spirit), the internal Jing-Qi-Shen triad becomes abundant, with these Three Treasures gathering in the central palace (Dantian). This allows natural communion between the water (kidneys) and fire (heart), and harmonious union of metal (lungs) and wood (liver).

The crux lies in focused mental stillness. The heart-mind acts as sovereign while the Shen serves as function. When heart-mind stabilizes, it returns to the central yellow court (middle Dantian), causing Qi to naturally condense and Jing to circulate fully. Practitioners must maintain constant vigilance, preserving their fundamental mind unwavering through all seasons and throughout life. This constitutes the essential method for observing the mind, calming thoughts, and concentrating the spirit.

The fourteenth verse reveals that the foundation of primordial Qi (Yuanqi) resides in kidney water. "Heaven generates water first, earth completes it in sixfold." Most sagehood cultivation originates here, through securing essence in the lower Dantian (lower abdomen). The kidneys divide into left (storing Jing) and right (preserving Qi) - seemingly separate yet fundamentally interconnected. Though Qi and Jing mutually depend, Jing remains primary. Kidneys belong to the water phase, yin in nature yet containing yang energy, like the Kan trigram (two yin lines embracing a yang line). Kidney water activity begins stirring between late Wu hour (11am-1pm) and early Wei hour (1-3pm), strengthens during Shen hour (3-5pm), peaks at You hour (5-7pm), then declines during Xu hour (7-9pm).

During the pivotal transition between Hai hour (9-11 PM) and Zi hour (11 PM-1 AM) when Yin and Yang alternate, this cyclical rhythm never errs. When water manifests as the body's vital essence (Jing), it embodies Yang within Yin; as blood, it becomes Yin within Yang—what postnatal existence calls blood corresponds to prenatal origin as essence, yet both are fundamentally "water." Practitioners seeking to raise water's Qi must essentially elevate the Yang energy within kidney water (Kan trigram), enabling it to merge at the body's center with the Yang energy surrounding heart fire (Li trigram). Simultaneously, the Yin energy surrounding kidney water balances with the Yin energy within heart fire at the central palace (spleen-stomach region). Thus when water ascends, fire descends; when fire descends, water rises. Through this mutual ascent and descent, the natural alchemical effect of metal-wood union and the convergence of the four celestial creatures (Azure Dragon, White Tiger, Vermilion Bird, Black Tortoise) is achieved.

(Section 15)

Mere discourse on heart-mind cultivation without addressing western metal Qi can never reveal the profound mystery of four-phase convergence. The Qi generated in the lungs corresponds to the Dui trigram of the west—only thus can essence accumulate to create the harmonious interaction of Qian (Heaven) and Kun (Earth).

The human body's four directions have distinct correspondences: the east belongs to wood governing the liver, the west to metal governing the lungs. The lungs' position in the upper body perfectly reflects metal's nature—Yang in essence yet Yin in form. Precisely because its form is Yin, it possesses heavy turbid descending qualities; because its essence is Yang, it holds light pure ascending attributes. Heavy matter naturally sinks, light matter inherently rises—this is fundamental principle. Metal Qi occupies the median between lightness and heaviness, lung Qi straddles ascent and descent: remove turbidity and it won't descend; eliminate levity and it won't ascend. Without ascent, Yang cannot manifest; without descent, Yin cannot persist—no Yang means no preciousness, no Yin means no substantiality. We treasure Yang Qi by preserving its lightness, value Yin Qi by retaining its turbid descent. Thus both floating and turbid Qi serve purposes, with Yin and Yang mutually complementing.

Turbid Qi naturally descends through rightward rotation, pure Qi naturally ascends leftward—this is Heaven's Dao in forward motion. Making pure Qi descend leftward and turbid Qi ascend rightward constitutes the reverse practice of cultivation. Forward motion follows natural law, reverse motion embodies active regulation through practice—thereby Yang within metal perpetually gathers at the central palace (Dantian) while Yin turbidity returns to the kidneys (Kun position). The essential method involves removing Yin turbidity to preserve Yang, with the core principle remaining heart fire's descent and kidney water's ascent. Thus metal's lightness naturally returns to the Dantian while turbid matter flows to the kidney region, fundamentally achieved through breath regulation (Shen absorption).

This passage explains the coordinated application of the Five Phases (Wood, Fire, Earth, Metal, Water) and the two energies of Yin-Yang in Daoist Neidan (internal alchemy) practice. The first poetic line, "water above and fire below link the two Qi (vital energies)," describes the meditative state where kidney water (associated with the North and Kan trigram) ascends while heart fire (associated with the South and Li trigram) descends. This state of "water and fire complementing each other" enables the complete harmony of the four symbolic animals (Azure Dragon, White Tiger, Vermilion Bird, Black Tortoise) representing Metal (West, Dui trigram) and Wood (East, Zhen trigram).

"The alternating use of two earths forms Wu-Ji" refers to the pivotal role of spleen earth (central Wu-Ji earth) in cultivation. By harmonizing Yin and Yang, practitioners ultimately attain the "purely Yang state where Yin recedes and Yang remains." Here, Wu earth belongs to Yang while Ji earth belongs to Yin—their union symbolizes the balance of Yin-Yang.

The text then details the characteristics of Wood nature (associated with the liver and East): while Wood's essence is inherently upright (Yang), its practical application requires flexibility (Yin). This interplay of firmness and pliability perfectly embodies the cultivation principle of Yin-Yang interdependence. The description of Wood following Yang Qi's leftward rotation and Yin Qi's leftward movement illustrates the importance of tracking the directional flow of these energies during practice.

The core process involves the "fusion of Metal and Wood": when heart fire descends from the South and kidney water rises from the North, true Qi condenses in the central palace (Middle Yellow), allowing Western Metal energy and Eastern Wood energy to naturally merge. This fusion requires conscious regulation by the Shen (spirit). Practitioners who master this principle of fire descending and water ascending can forge a purely Yang body—symbolized by the image of a perfected being seated upon the purple throne (representing the Niwan Palace in the head).

The second poem concludes that while the relationship between Middle Yellow (middle Dantian) and the four symbols has been clarified, the Yin-Yang application of Wu-Ji earth demands further explanation. The "knife-measure method" refers to ancient alchemical terminology denoting subtle cultivation techniques. The final line suggests that only through genuine comprehension of these essentials can one fully grasp the profound meaning of the Yellow Court Scripture.

In the theory of the Five Phases (Wuxing), the Earth phase occupies the central position yet divides into two natures: Wu Earth (Yang Earth) and Ji Earth (Yin Earth). This differentiation occurs because Earth Qi (vital energy) undergoes transformation under the influence of seasonal climatic changes—spring belongs to Lesser Yang, summer to Greater Yang, autumn to Lesser Yin, and winter to Greater Yin. Precisely through these seasonal variations, the Earth phase manifests both Yin and Yang attributes.

Heaven manifests the four seasons of spring, summer, autumn, and winter, while Earth embodies the four directions of east, south, west, and north. Spring Qi resides in the east, summer Qi in the south, autumn Qi in the west, and winter Qi in the north. The dual forces of Yin and Yang circulate ceaselessly between Heaven and Earth, driving the movement of the Five Phases. Among the four phases of Wood, Fire, Metal, and Water, the Earth phase remains indispensable. The celestial stems and earthly branches correspond with the seasons: spring and summer align with Lesser Yang and Greater Yang, while autumn and winter correspond to Lesser Yin and Greater Yin. When Earth Qi flows through spring and summer, it exhibits Yang Earth (Wu Earth) characteristics; when circulating through autumn and winter, it manifests Yin Earth (Ji Earth) properties.

Yang Earth governs growth and germination, whereas Yin Earth oversees maturation and storage. However, the function of storage proves less visibly potent than that of growth, making Yang Earth more prominent while Yin Earth remains secondary. Yet without Yang Earth, growth becomes impossible, and without Yin Earth, storage cannot occur—the two complement each other in indispensable harmony. Practitioners of the Dao must guide the Four Symbols (Azure Dragon, White Tiger, Vermilion Bird, and Black Tortoise) to return to the central palace of Earth, enabling the four phases of Wood, Fire, Metal, and Water to flourish within Earth. When Earth prospers, all four phases thrive. Initially, both Wu and Ji Earth work in concert, ultimately merging into pure Yang Earth—transforming Ji Earth into Wu Earth, whereby the Kun hexagram (pure Yin) becomes the Qian hexagram (pure Yang).

At this stage, the Yang Spirit (Yang Shen) can ascend to Heaven. In practical cultivation, the palms serve as crucial regulators of these two Earth energies, while the Original Spirit (Yuan Shen) acts as their sovereign commander. The Four Symbols submit to Earth's governance, Original Essence (Yuan Jing) nourishes Earth, and Original Qi (Yuan Qi) circulates through it. Thus, the vital importance of Earth phase in the human body becomes self-evident.

The eighteenth passage discusses the cultivation of spiritual work (Xing Gong): human Shen (spirit) and Qi perpetually circulate within the body. Their movement follows distinct pathways—leftward rotation belongs to Yang, rightward to Yin, creating dual trajectories of Yin-Yang circulation. This dynamic interplay of Shen and Qi operates ceaselessly, manifesting concretely as 3,250 distinct transformations (this numerical reference likely holds specific significance in cultivation practices).

Between breaths lies Qi (vital energy), within which resides Shen (primordial consciousness). The Shen governs the movement of Qi, while Qi propels the manifestation of Shen. There exists both the perceptible interplay of Shen and Qi that we can sense, and the imperceptible workings of these forces beyond our awareness.

The perceptible activities of Shen-Qi are driven by acquired consciousness (postnatal mind), while the imperceptible operations stem from innate Qi (primordial life energy). This innate Qi circulates with clockwork precision throughout the body—from 11 PM to 11 AM (the Yang phase), it spirals upward in leftward rotation; from 11 AM to 11 PM (the Yin phase), it ascends in rightward rotation. This Yin-Yang Qi cycles continuously within us. When Qi is abundant, the flow of Shen-Qi remains unobstructed; when deficient, blockages occur—unimpeded flow dispels all ailments, while stagnation breeds countless diseases. The innate Qi serves as both the master and pathway for Shen-Qi circulation.

After age sixteen, our innate Qi gradually diminishes, and the channels for Shen-Qi begin clogging. Initially manifesting as subtle disruptions, these progress to partial blockages, eventually causing illness or death. Daoist practitioners (cultivators of the Dao) must employ acquired consciousness to guide Shen-Qi, reopening these channels to restore circulation—top to bottom, back to front, interior to exterior—mirroring the natural rhythms of sun and moon, the turning of seasons. Through cultivation that follows Yin's waning and Yang's waxing, one returns from the Bo hexagram (Yin dominance) to the Fu hexagram (Yang rebirth), progressing to the Qian hexagram (pure Yang), ultimately refining a body of pure Yang to attain longevity.

Truthfully, innate Qi possesses fixed left-right circulatory pathways, though restoring their original state proves challenging. By directing Shen-Qi through focused intention, its movement naturally achieves ideal patterns. Therefore, during Zi hour (11 PM-1 AM) cultivation, one must seize the pivotal moment when Yin exhausts and Yang births, applying leftward rotation; at Wu hour (11 AM-1 PM), capture the transition from exhausted Yang to nascent Yin using rightward rotation. During practice, simply maintain awareness at the central palace (Dantian), and the left-right rotations will form spontaneously with impeccable timing.

(Background note: The described "Zi-Wu practice" represents a core Neidan (internal alchemy) method in Daoism. Through breath guidance and mental focus during specific celestial hours, it mimics cosmic Yin-Yang cycles to replenish primordial Qi. The "left-right rotations" refer to the spiral trajectories of internal Qi movement, corresponding to Earth's rotation and celestial motions.)

This passage explains the specific methods of the "extraction and replenishment" (choutian) practice in Daoist cultivation. "Extraction and replenishment" is a technique for regulating the yin and yang energies (Qi) within the body, primarily performed during the mao hour (5-7 AM) and you hour (5-7 PM).

During practice, when the yin and yang energies reach their peak vitality, they must be promptly regulated. The key is to gather and store the Qi in the "Yellow Palace" (referring to the Dantian, the energy center). The specific method involves using intention to guide the Qi to accumulate in the middle Dantian, after which it naturally circulates through the limbs. This continuous flow of Qi marks the beginning of the extraction and replenishment practice.

The method of "extraction" is as follows: First, gather the Qi in the middle Dantian until it becomes abundant, then allow it to circulate naturally from west to east. Visualize this circulation occurring 36 times, corresponding to the celestial cycles. This constitutes one "extraction." Next, guide the Qi downward from the navel to the coccyx, then upward to the Kunlun point at the crown of the head, entering the Mingtang point, descending to the throat, and finally returning to the upper Dantian. This east-to-west circulation is repeated 36 times, completing the second "extraction." Following this sequence seven times achieves the full "extraction" process, resulting in the harmonious interaction of water and fire (yin and yang) and the union of metal and wood (the Five Phases).

The method of "replenishment" is accomplished through breath regulation: Begin by exhaling once and inhaling twice, then exhaling twice and inhaling three times, gradually increasing the number of exhalations until reaching a state of inhalation without exhalation. When both inhalation and exhalation cease, the mind (Shen) settles peacefully in the middle Dantian. The number of replenishments matches the extractions—seven repetitions.

Upon completing these steps, guide the Qi downward from the navel to the perineum, passing through the Yin Qiao meridian, the Wuli point, and the Lidui point, then circling to the Yongquan point. From there, it ascends through the popliteal fossa behind the knee, traversing the Three Passes, Nine Palaces, and Six Chambers, before returning to the middle Dantian. This cycle is repeated seven times in each direction, then the Qi returns below the navel, continuing to circulate along this pathway.

This passage elucidates the essential techniques of "extraction and replenishment" (choutian) and temporal cultivation in Daoist practice. "Extraction and replenishment" are Neidan (internal alchemy) terms where "extraction" refers to drawing forth essential energies while "replenishment" denotes supplementing vital forces. The practice must align with specific temporal phases: the "extraction" method should follow the Zi hour (11 PM-1 AM), while "replenishment" is performed after the Wu hour (11 AM-1 PM), thereby enhancing cultivation efficacy. Among the four cardinal hours (Zi, Wu, Mao, You), Zi and Wu are primary while Mao and You serve complementary functions.

The cultivation process unfolds in three stages: initial maintenance of Wuwei (non-action), followed by conscious application of extraction-replenishment techniques, culminating in a return to non-action. After completing these operations, practitioners should sit quietly to nurture Qi (vital energy), gathering breath in the central palace (Dantian region) to allow natural Shen (spirit) condensation. When the spirit concentrates in the Yellow Court (middle Dantian), vital energy naturally becomes abundant. The four cardinal hours form an interconnected system where none can be neglected.

The verse mentions "Zi-Wu-Mao-You achieve complete merit, while Chen-Xu-Chou-Hai mark eight empty periods," indicating these four hours yield optimal cultivation results while other periods remain secondary. The crux lies in mastering Shen condensation methods and meticulously perceiving the movement patterns of true Qi within the body.

The fundamental operation of heaven and earth rests upon Yin-Yang alternation. Daytime belongs to Yang through solar motion, while nighttime pertains to Yin via lunar movement. The sun embodies Yang's essence, the moon contains Yin's quintessence. Their revolutions create day-night cycles divided into twelve two-hour periods, each bearing distinct Yin-Yang attributes: Yang energy initially emerges at the fourth mark of Zi hour, peaks at Wu hour's fourth mark before transitioning to Yin, cycling endlessly. Practitioners must harmonize with these natural rhythms, harvesting Yang during its ascendance and nurturing Yin during its growth.

This scripture emphasizes aligning cultivation with celestial timing, comprehending the natural laws of Yin-Yang waxing and waning. Through temporal-specific cultivation methods, practitioners achieve the effects of spirit condensation and energy accumulation.

All things between heaven and earth embody the dual attributes of Yin and Yang. Though divided into Yin and Yang, they are fundamentally interdependent. The moon belongs to Yin yet relies on the sun's Yang Qi (vital energy), while the sun belongs to Yang yet requires the moon's Yin softness. Yin and Yang serve as each other's foundation, like dance partners eternally accompanying and generating one another.

The human body similarly inherits the Yin-Yang energies of heaven and earth. The circulation of Qi and blood ebbs and flows like the alternation of sun and moon. During the Zi hour (11 PM - 1 AM), Yang Qi begins to stir as Qi and blood rotate leftward; during the Wu hour (11 AM - 1 PM), Yin energy emerges as Qi and blood rotate rightward. This cyclical movement perfectly mirrors the rhythms of heaven, earth, sun and moon.

Practitioners must seize the pivotal moments of Yin-Yang transformation: during the Zi-Wu periods when Yin and Yang first stir, they engage in the cultivation of "water and fire intermingling" (regulating the Qi of heart and kidneys); during the Mao-You periods (5-7 AM and 5-7 PM) when Yin and Yang reach peak activity, they practice "metal and wood merging" (harmonizing the Qi of lungs and liver). The remaining eight two-hour periods must not be neglected either, requiring eight methods of regulation:

First, comprehending principles when encountering affairs; second, maintaining serene awareness without attachment; third, regulating the rhythm of breathing; fourth, speaking with careful restraint; fifth, carrying oneself with dignified composure; sixth, keeping thoughts free from agitation; seventh, shielding against external temptations; eighth, moderating sleep and nourishment. Persisting in these eight cultivation methods ensures the abundant flow of water-fire Qi during Zi-Wu periods and the smooth merging of metal-wood Qi during Mao-You periods. This constitutes the marvelous method for self-cultivation to enter the Dao and the secret for attaining immortal authenticity.

Regarding the profound principles of dual cultivation of nature and life (Xingming Shuangxiu), the Daoist patriarchs have already revealed complete teachings. We who are fortunate to receive these great truths should carefully contemplate and investigate them, preparing the altar at midnight to burn incense and invite the patriarchs' guidance. The venerable Liu Haichan (famous Northern Song dynasty Daoist master) once personally descended to the altar to expound these mysterious principles in detail for his disciples.

Patriarch Lü (Lü Dongbin) said: The profound mysteries of Dao cultivation require both internal and external practice. External efforts must harmonize with internal refinement—when one's Dao attainment reaches a certain level, celestial assistance will naturally follow. In cultivation, one should proceed with composed ease, maintaining stability as if standing atop a jade rooster's head.

The crux of Neidan (internal alchemy) practice lies in the "One Qi" (primordial vital energy), whose foundation resides in breath regulation. The essence of breathing lies in nurturing Qi, the core of Qi regulation is maintaining equilibrium (central harmony), the basis of equilibrium is concentrated Shen (spirit), and the key to concentration is comprehending the Dao's principles. Taking the enlightenment of humanity as my mission, I now elucidate these profound truths.

What we call "profound" (xuan) refers to Yang Qi, while "foundation" (ji) denotes the root. To achieve the true Dao, one must first establish this Yang Qi foundation. To build this foundation, discern truth from falsehood. By adhering to this fundamental principle, one's Shen naturally stabilizes, Qi naturally harmonizes, and breathing naturally follows its rhythm. When mundane Qi dissipates and true Qi manifests, employ the "Qi Subduing Method": first exhale once and inhale twice, then exhale twice and inhale thrice—repeat this seven times, allowing Qi to circulate the Central Palace (Dantian) while drawing and rotating it.

Five Qi circulations constitute one drawing cycle, after which Qi returns to the Qi Sea, passes through the Tail Lü (coccyx region), ascends through the Three Passes (key points along the Governing Vessel), enters the Mud Ball Palace (Baihui point at the crown), descends from the Bright Hall (mid-brow area), crosses the Sparrow Bridge (tongue touching palate), enters the Multi-Storied Tower (throat), and finally returns to the Earth Cauldron (lower Dantian). Five such circulations complete the second drawing. Seven full drawing cycles accomplish the Six Yang (celestial orbit) circulation.

At this stage of cultivation, the heart-mind dwells peacefully in the Yellow Court (middle Dantian). In deepest stillness, one enters Wuwei (non-action), becoming unaware even of one's physical form—let alone the vastness of heaven and earth, the movements of sun and moon, or the multitude of creations. The mind becomes empty yet expansive, utterly unconstrained and freely wandering.

Regarding the "Replenishment" practice, it too fundamentally involves breath techniques. This "Replenishment" should be performed during the You hour (5-7 PM, when Yin Qi peaks), as the body's Yang Qi may then be insufficient, requiring postnatal breathing to supplement prenatal Qi. Begin by maintaining Wuwei stillness, calmly regulating breath until Shen and Qi flow naturally, then commence Replenishment:

First rotate seven circles leftward around the navel's exterior, then five circles rightward—repeat this left-right sequence three times. Coordinate with special breathing patterns: exhale 1-inhale 2, exhale 2-inhale 4, exhale 1-inhale 3, exhale 2-inhale 5, exhale 1-inhale 1. Then rotate seven leftward circles around the navel as Qi descends to the perineum, dividing into two pathways along the arms, passing through the Five Li point, Yin Crossing point to the Severe Exchange point, turning toward the Bubbling Spring point, then ascending behind the knees to the popliteal center.

This passage elucidates the essential techniques of breath circulation in Daoist Neidan (internal alchemy) practice. During cultivation, the internal Qi flows from the coccyx (tailbone) through the spinal column, ascends past nine key cavities and six vital palaces (important acupoints in the body), reaches the Mingtang (third eye point between eyebrows), proceeds to Xuanying (throat), then moves to Qimen (chest acupoint) before entering the Huangting (Dantian region).

The practice method involves circulating the breath clockwise through this pathway twenty-one times, repeating this cycle three times to complete one session. Initially, the practitioner must consciously guide the Qi flow, but later stages should follow natural spontaneity. When the Qi stabilizes within the body and the Shen (spirit) peacefully resides in the Dantian, entering a state of profound stillness, one experiences bodily lightness like floating clouds, a transcendent sensation with complete physical ease. This constitutes the crucial technique for Mao-You period practice (5-7am and 5-7pm).

The Zi-Wu period practice (midnight and noon) differs significantly: during Zi hour (midnight) when Yang Qi first emerges, and Wu hour (noon) when Yin Qi begins to arise, the Qi remains extremely subtle. Here one must avoid forceful guidance, maintaining serene patience to preserve the innate Qi (prenatal vitality), nurturing the Shen without distraction, allowing spirit to guard Qi without dissipation. This Wuwei (non-action) approach represents exquisite subtlety—only during Mao-You periods can active cultivation methods be implemented.

The principle applies similarly to seasonal cultivation: without Zi-Wu period practice, Mao-You period Qi cannot strengthen; without Mao-You practice, Zi-Wu period Qi cannot stabilize. Just as seasons alternate without conflict and sun-moon cycles don't interfere, practitioners following this method establish Yang Qi foundations that gradually strengthen while Yin Qi transforms. This process mirrors the hexagram transitions from Bo (Yin dominance) returning to Qian (pure Yang), then transforming to Kun (pure Yin), ultimately achieving perfect Yang state. Thus one's true nature manifests spontaneously, establishing the dual cultivation of Xing (nature) and Ming (life), forming the Yin-Shen (a spiritual form of original spirit) to become a Perfected Being with spiritual awareness.

Later, the Perfected Master Shi (a Daoist immortal) through planchette writing (a spirit communication method) instructed: "The Dao of breathing appears simple yet contains profound depths. Humans begin autonomous breathing only after birth, yet respiratory activity exists in the womb. Fetal breathing synchronizes with the mother's respiration—while apparently connected to the mother, it actually communicates with Heaven-Earth Qi. That pre-natal state, undisturbed by emotional desires, maintains naturally elongated breath—this is the 'embryonic respiration' state. This prenatal breathing represents the primordial Yang Qi inherited from our parents: its preservation means life, its loss brings death. After birth, visual and auditory capacities develop first, followed by speech and cognition—all these represent acquired functions."

This scripture expounds the vital importance of breath control in Neidan (internal alchemy) cultivation. When humans are disturbed by the six desires (of eyes, ears, nose, tongue, body, and mind) and seven emotions (joy, anger, sorrow, fear, love, hate, and desire), their breathing becomes disordered. External disturbances cause uneven Qi flow and unsettled Shen (spirit), leading to irregular respiration characterized by shallow inhalation and excessive exhalation. Prolonged imbalance results in insufficient absorption of heaven-earth essence while one's primordial Qi continually dissipates, ultimately leading to the exhaustion of Jing (essence) and physical demise.

The Daoist practice hinges on "Qi accumulation" — gathering primordial energy through breath regulation. The method involves first calming the mind to achieve even, rhythmic breathing. Once stabilized, practitioners employ the "breath absorption" technique: beginning with equal inhalation and exhalation, then gradually increasing inhalation until reaching a state of predominant inhalation over exhalation. Sustained practice causes Qi to circulate internally — rotating swiftly like a wheel from the central palace (Dantian region) to the navel, ascending along the spine to the Muddy Pellet (Baihui point at the crown), then descending through the Jade Pillow (throat) to return to the Earth Cauldron (lower Dantian).

Through prolonged internal respiration, true Qi gathers in the Central Yellow (middle Dantian), permeating the entire body to transform Yin Qi into Yang Qi, converting crimson blood-energy into luminous white Qi, and purging turbid Yin energies. Ultimately, this manifests the Yang Shen (pure Yang spirit), forging an indestructible diamond body. The text distinguishes ordinary breath (Qi) from internal respiration (primordial Qi), emphasizing Shen's role in regulating breath.

Patriarch Liu Haichan ultimately reveals: Dao cultivators who fathom breath regulation's mysteries attain Dao and longevity. Moved by the seeker's sincerity, he descended specifically to impart this essential teaching. This scripture highlights breath cultivation as foundational Neidan practice for physical-spiritual transformation.

This scripture elucidates the core principles and concrete methods of Daoist Neidan (internal alchemy) practice.

Regarding the essential technique of "absorbing the One and returning to the Three": Here the "One" refers to the primordial Qi of the universe (cosmic source energy), while the "Three" denotes the three vital life elements - Jing (essence), Qi (vital energy), and Shen (spirit). The primordial Qi represents the origin of all things, from which Qi emerges, then transforms into Jing, and finally manifests as Shen. The key to cultivation lies in anchoring this primordial Qi in the lower Dantian (the golden palace within the yellow court). Through focused concentration and single-minded devotion, one can achieve abundant Qi, flourishing Jing, and freely circulating Shen. The specific practice involves seizing the subtle opportunities of Yin-Yang transformation during the four cardinal hours (Zi, Wu, Mao, You - crucial moments of daily cosmic transitions).

The twelve-stage method for cultivating spiritual nature transmitted by Master Xi Baipeng:

1. Develop clear discernment when encountering affairs

2. Harmonize with seasonal changes

3. Regulate breathing patterns

4. Gather primordial Qi through seated meditation

5. Withdraw visual focus inward

6. Guide inhaled breath to the middle Dantian

7. Contain exhaled breath without dispersion

8. Circulate Qi along the central channel

9. Direct Qi flow from back to front

10. Guide Qi movement from upper to lower regions

11. Enter the state of hazy oblivion

12. Attain awakening of the primordial Shen

Progressive effects of sustained practice: From one day to nine years, each phase yields distinct advancements. The first year establishes foundations, the fourth year eliminates distracting thoughts, the sixth year manifests great illumination, the seventh year achieves the Golden Elixir, and by the ninth year the Yin-spirit can leave the body, becoming a Perfected Being of spiritual awareness. Thereafter, one must gather primordial cosmic Qi to harmonize Yin and Yang.

This passage presents two main themes: the author's personal journey of cultivation in pursuit of the Dao, and the strict precepts governing the transmission of Daoist teachings.

Originally a Confucian scholar studying the ways of Confucius and Mencius, the author understood the principles of self-cultivation yet never grasped the true method for perfecting body and mind. After suffering from an illness for ten years without cure, everything changed in the autumn of the Gengwu year when he sought remedies at the ancestral altar (a Daoist Patriarch's shrine). Through the Patriarch's compassion, he received a prescription that finally healed his chronic condition, leading to his full conversion to Daoism. After fourteen years of devoted study into profound mysteries, during the winter of the Guiwei year, he received divine revelation through spirit writing (a Daoist mediumistic practice). Together with fellow practitioners Cheng Dezhen and Pan Shengzhen, they completed this scripture. The author deeply feels the weight of responsibility, fearing any failure to honor the Patriarch's grace.

The text particularly emphasizes strict transmission rules: seven types of people must never receive these teachings casually—the disloyal and unfilial, the unkind and unmerciful, those incapable of comprehension, those who disregard rules, those unable to maintain secrecy, non-Daoist practitioners, and anyone lacking the Patriarch's permission. Indiscriminate transmission to unworthy recipients constitutes a grave offense against the Patriarch.

The latter section employs Yi Jing (Book of Changes) hexagrams to explain the growth patterns of primordial Qi in the human body: infancy (ages 1-3) corresponds to the Kun hexagram (pure Yin), when primordial Qi begins developing; by age 5, the first Yang emerges (Fu hexagram); at 8, the second Yang (Lin hexagram); at 10, the third Yang (Tai hexagram); and by 13, the fourth Yang (Dazhuang hexagram). Here, the ancient weight measurement of sixty-four zhu serves as a metaphor for the gradual accumulation of primordial Qi.

This passage describes the process of primordial Qi (the innate vital energy) being gradually depleted with age, using the twelve "growth and decline hexagrams" from the I Ching's sixty-four hexagrams (representing the waxing and waning of Yin-Yang) as metaphors for cultivation opportunities at different life stages.

At sixteen years old, the accumulated primordial Qi in the body reaches 384 zhu (an ancient unit of weight symbolizing the celestial cycle number), corresponding to the pure Yang state of the Qian hexagram (䷀). At this stage, with abundant Jing (essence) and Qi, one can easily achieve success in cultivating both nature (spiritual refinement) and life (vital energy) under proper guidance. However, every eight years thereafter, sixty-four zhu of primordial Qi is consumed:

From sixteen to twenty-four corresponds to the Gou hexagram (䷫), where the first Yin line emerges—desires begin stirring but depletion remains slight, making recovery through timely cultivation still achievable. At thirty-two, the Dun hexagram (䷠) appears as Yang Qi further declines, yet with vigorous vitality, laying the foundation (Zhuji) for practice is still feasible. Forty years old aligns with the Pi hexagram (䷋), where Yin and Yang cease interaction, requiring cultivation to reverse the decline. Forty-eight corresponds to the Guan hexagram (䷓), with Yin Qi dominant—one must nurture the faint remaining Yang energy. At fifty-six, the Bo hexagram (䷖) shows only a single Yang line remaining, like a dying ember. By sixty-four, primordial Qi is exhausted, returning to the pure Yin state of the Kun hexagram (䷁).

Yet the scripture emphasizes that even in advanced age, through persistent practices like "gathering the medicine" (harvesting heaven-earth spiritual energy) and "transplanting and connecting" (replenishing primordial Qi through specific methods), one can reverse the Yin-Yang decline. This embodies the Daoist cultivation philosophy that "my destiny lies with me, not heaven."

This scripture primarily elucidates the laws of birth-death cycles and the cultivation path to transcend them.

The text states that without encountering a true spiritual teacher (zhiren, perfected person) and diligently practicing, one can only sustain life through post-heaven nourishment of food essence (Jing), never accessing the pre-heaven primordial Qi (Yuanqi), and thus failing to attain immortality. It describes the cyclical process of life: from emptiness transforming into spirit (Shen), spirit into Qi, Qi into blood, blood into physical form, form into infancy, then childhood, adolescence, prime years, old age, and finally death returning to emptiness—an endless repetition. All beings are bound to this cycle of birth and death, endlessly adrift in the sea of suffering.

The author urges contemplation of two fundamental questions: Before my parents conceived me, where did life originate? After the dispersal of my soul, where does death lead? Life and death are interdependent—without life there is no death, and without death there is no life. Ordinary people are trapped by birth and death, while true cultivators (zhiren) transcend them. What is subject to birth and death is the body; what is deathless is the original mind. When awakened, the mind lives; when deluded, the mind dies.

Immortals and Buddhas, compassionate toward sentient beings, reveal that all life inherently possesses spiritual awareness, merely obscured by delusion. Without awakening, one endlessly degenerates through reincarnation, even reborn as lower creatures. By cultivating the sacred path, one can permanently sever delusions, attaining the Daoist immortality or the Buddhist deathless state.

Finally, The Orthodox Lineage of the Mysterious Origin presents three essential cultivation stages: First, comprehend the Dao’s principles and stabilize the mind, reaching a state where understanding and reality merge—this is called the "wise person" (zhiren). Next, guide the mind into the Qi ocean (Qi chamber), achieving harmony of heart and Qi with concentrated spirit—this is called the "true person" (zhenren). Ultimately, lead Qi into the spirit chamber, dissolving subject-object duality and transcending even sagely wisdom to attain divine marvels—this alone is called the "perfected person" (zhiren). These three stages, progressing step by step, serve as vital guidance for cultivation.

This passage elucidates the essential principles for cultivating mind and nature. The opening line speaks of "the light of wisdom illuminating the ten directions," describing how "in emptiness, transformation occurs through wuwei (non-action)," reaching the state of uncontrived naturalness. The subsequent verse explains: the heart serves as the luminous sovereign of the body, while shen (spirit) governs the Three Treasures (jing/essence, qi/vital energy, and shen/spirit).

For Daoist practitioners, comprehending this principle brings the same profound understanding as studying ten thousand volumes of scripture. The crux lies in recognizing the true nature of heart-mind and apprehending the mystery of spiritual consciousness, ultimately returning to the natural state of emptiness. This teaching emphasizes that the core of cultivation resides in regulating the heart and nurturing shen, achieving unity with the Dao through inner contemplation and self-reflection to realize one's original mind.
