《會真集》

Taiji (the Supreme Ultimate, representing the primordial chaos of the universe) is another expression of Wuji (the Limitless), beyond definition by concrete names. It exists in an undifferentiated state of chaos, containing within it the mystical number fifty-five, while already encompassing the two polarities of Yin-Yang, the three luminaries (sun, moon, and stars), the four phases (Lesser Yang, Greater Yang, Lesser Yin, Greater Yin), and the Five Phases (Metal, Wood, Water, Fire, Earth). Though possessing essence, it has no concrete form—this is what Laozi described as "there was something formless yet complete." The Jade Strategy scripture records: Before heaven and earth separated, the Qi (vital energy) was turbid and indistinct. Practitioners of the Dao must understand this primordial Qi as the source from which all things emerge.

When the Five Ultimates (Taiyi, Taichu, Taishi, Taisu, and Taiji) differentiated and Yin-Yang separated, the four phases gradually took shape in the unseen, while the Five Phases subtly manifested. The colors of Qi transformed continuously: the original chaotic Qi turned black after a million years, representing the Water phase with the generative number one. This "one" is the origin of the Qian (Heaven) trigram and the foundation of the Bagua (Eight Trigrams), giving rise to "Jia," the first of the Heavenly Stems and the beginning of the Five Phases and the ten Heavenly Stems. Ancient sages observed these transformations, mapping celestial patterns to record astronomical phenomena. Later sages followed these principles to establish the calendar, making the cyclical patterns of time discernible.

After another million years, the black Qi turned red, representing the Fire phase with the generative number two, marking the start of the Xun (Wind) trigram and producing the Heavenly Stem "Xin." The red Qi, after another million years, transformed into a bluish-green hue, representing the Wood phase with the generative number three, initiating the Gen (Mountain) trigram and producing the Heavenly Stem "Gui." The bluish-green Qi, after another million years, shifted to white, representing the Metal phase with the generative number four, forming the basis of the Kun (Earth) trigram and again producing "Gui." Finally, after another million years, the white Qi turned yellow, representing the Earth phase with the generative number five, initiating the Li (Fire) trigram and producing the Heavenly Stem "Ji."

The evolution of the Five Phases from generative to completion numbers follows this pattern: The odd numbers one, three, and five combine to form the Yang number nine, governed by the Heavenly Stems Jia and Bing, acting as the "guest." The central Earth number five, combined with the Li trigram's Ji (Earth) and Jia (Wood), and the Water number one plus its completion number six descending, gives rise to the Kun trigram's Yi (Wood)—thus, movement begins with the "guest." The even numbers two and four combine to form the Yin number six, governed by Xin and Gui, acting as the "host." The Earth number five plus the Fire number two yields the completion number seven, ascending to produce the Zhen (Thunder) trigram's Geng (Metal). Yi (Wood) and Geng (Metal) combine, creating the north-south alternation—hence, movement follows with the "host."

This scripture elucidates the principles of correlating the Five Phases (Wuxing) and Eight Trigrams (Bagua) with celestial stems and earthly branches in Daoist Neidan (internal alchemy) practice, using numerical symbolism to represent Yin-Yang transformations. Let me explain layer by layer:

In the Five Phases system, Water corresponds to the number one, Fire to two, and Earth—as the source of all things—to ten. This combination forms the pairing of the Kan trigram (representing Water) with Wu Earth. The numbers generated by Fire correspond to the Xun trigram (Wind) and Xin Metal. When Earth combines with Wood's number three through the Gen trigram (Mountain) and Bing Fire, it forms the number eight, generating the Dui trigram (Marsh) with Ding Fire. The numbers derived from Water correspond to the Qian trigram (Heaven) and Jia Wood, which then combines with the central Earth number five and Metal's number four through the Kun trigram (Earth) and Gui Water, completing the number nine and generating Qian trigram with Ren Water. Thus Ding and Ren harmonize, enabling the mutual transformation of Qi between eastern and western directions.

Through numerical calculations of Yin-Yang (Yang numbers nine, Yin numbers six) and the cyclical matching of stems and branches, the Na-Jia system (correlating celestial stems with trigrams) reveals patterns of ascent and descent. When Water and Fire achieve equilibrium, three Yang aspects manifest while four Yin aspects remain latent; when Wood and Metal intersect, emptiness and form exchange positions. These are the fundamental laws through which the Dao generates all things. By mastering these principles, practitioners can attune themselves to celestial auspicious signs.

The specific calculation method proceeds as follows: Central Earth five plus Water one yields six, generating Kun trigram with Yi Wood; Earth five plus Fire two yields seven, generating Zhen trigram with Geng Metal; Earth five plus Wood three yields eight, generating Dui trigram with Ding Fire; Earth five plus Metal four yields nine, generating Qian trigram with Ren Water; Earth five plus Earth five yields ten, generating Kan trigram with Wu Earth. Thus the Eight Trigrams perfectly match the Ten Celestial Stems, embodying the undifferentiated chaos where mother and child embrace before Yin-Yang separation.

The pairing of Qian (Heaven) and Kun (Earth) forms complete numerical patterns: Yang descends while Yin ascends, rotating left and right while connecting above and below. This manifests concretely as: one and nine combining to make ten (Ren meeting Jia), where Qian paired with Kun generates Kan trigram containing Jia and Yi; four and six combining to make ten (Yi transitioning with Gui), where Kun paired with Qian generates Dui trigram containing Gui and Ren; three and seven combining to make ten (Geng meeting Bing), where Qian paired with Kun generates Zhen trigram containing Bing and Ding; two and eight combining to make ten (Ding meeting Xin), where Kun paired with Qian generates Li trigram containing Geng and Xin. The Li trigram incorporates Ji Earth to obtain number five, while Kan trigram incorporates Wu Earth to obtain number ten—together making fifteen, the central numerical harmony between Heaven and Earth.

Finally, the text explains how the Two Polarities (Yin-Yang) generate the Four Symbols (Lesser Yang, Greater Yang, Lesser Yin, Greater Yin). Here the Kan trigram's complete number six retains its original three while adding another three to generate Qian trigram incorporating Ren but not Gui, demonstrating the generative patterns of Qian-Kun pairing. The entire system reveals the precise numerical relationships of mutual rooting between Yin-Yang and the generative-conquest cycles of the Five Phases.

This scripture primarily discusses the relationship between the Eight Trigrams (Bagua), Five Phases (Wuxing), and the Heavenly Stems and Earthly Branches in Daoist internal alchemy (Neidan) practice, as well as the principles of Yin-Yang's ascending and descending transformations.

The text explains the correspondences between the Eight Trigrams (Qian, Kun, Zhen, Xun, Kan, Li, Gen, Dui) and the Heavenly Stems (Jia, Yi, Bing, Ding, etc.). For instance, the Kun trigram corresponds to Yi but not Jia, while the Qian trigram corresponds to Jia. The Li trigram is associated with the number seven, retaining three internally and manifesting four externally, while the Zhen trigram is associated with the number eight, retaining three internally and manifesting five externally. These numerical relationships form the mutual generation and restraint cycles of the Five Phases, giving rise to the various transformations of the Eight Trigrams.

It particularly emphasizes the principle of Yin-Yang inversion: metal (金) arises from water (水), earth (土) emerges from metal, and wood (木) is born from fire (火). Additionally, it highlights the unique nature of the Heavenly Stems Wu and Ji—they lack direct trigram correspondences. Wu, being Yang, is attributed to the Kan trigram (representing the middle son), while Ji, being Yin, is attributed to the Li trigram (representing the middle daughter). This completes the full integration of the ten Heavenly Stems with the Eight Trigrams.

Practitioners must deeply comprehend these patterns of Yin-Yang movement and trigram transformations. By observing the natural laws of celestial motion and the alternation of sun and moon, they can grasp the essential techniques of internal alchemy. When cultivation reaches the stage where essence (Jing) and vital energy (Qi) coalesce and the "gold-mercury" (a Neidan term referring to the refined union of Jing, Qi, and Shen) takes form, the divine elixir (Shen Dan) can be achieved. The key lies in meticulously studying the trigrams and their line statements, mastering the cyclical patterns of Yin-Yang waxing and waning, and maintaining unwavering mental focus to attain the highest state of cultivation.

Finally, it underscores that the ten Heavenly Stems and Eight Trigrams embody the transformations of the Five Phases and Four Symbols (Sixiang), as well as the cyclical shifts among the cardinal directions—north, south, east, and west. Among them, the Kan and Li trigrams serve as the crucial gateways of practice, while the Qian and Kun trigrams function as the cauldron and furnace of alchemy. Practitioners must internalize the laws of cosmic creation, aligning their cultivation with the movements of the sun and moon—this is the true Dao of spiritual refinement.

Between inhalation and exhalation lies a complete Zhou Tian cycle (referring to the full circulation path of Qi within the body), where the gathering and dispersing of breath determines the fundamental state of life. What Laozi called the "Mysterious Feminine Gate" (the root of Yin-Yang interaction) is precisely the foundation of all things in heaven and earth. When Yang Qi circulates (Yang Fu), Kun (Yin) follows Qian (Yang) ascending from the left; when Yin Qi dominates (Yin Zhi), Qian (Yang) harmonizes with Kun (Yin) responding from the right. This ceaseless coming and going of Yin and Yang perfectly corresponds with the transformational principles of the Bagua (Eight Trigrams).

The cultivation formula states: During exhalation, the number seven forms (Li trigram belonging to Fire), where true water within fire descends, Ji Earth combines with Jia Wood, and Jia Wood joyfully ascends into the Shen palace. During inhalation, the number six forms (Kan trigram belonging to Water), where true fire within water rises, Wu Earth combines with Gui Water, and Gui Water willingly descends into the Dantian. The pairing of Ding Fire and Ren Water resembles the Li trigram, while Ji Earth enables the communication of mountain and marsh Qi. Yi Wood and Geng Metal's mutual attraction returns to the Kan trigram, with Wu Earth stimulating wind and thunder. Thus the Four Symbols (Lesser Yang, Greater Yang, Lesser Yin, Greater Yin) return to the Golden Cauldron, the Five Phases (Metal, Wood, Water, Fire, Earth) gather in the Jade Furnace, Bing Fire meets Xin Metal, and Qian-Kun unite as one. The movement of Wu-Ji returns the ten heavenly stems to their origin—gathered together like clenched fingers, dispersing again to their respective positions.

The so-called "inversion of the Five Phases" means: The Kan trigram belongs to Water yet generates Metal (Qian Metal conceals Jia-Yi Wood, with Wood's growth peak at Hai hour); the Dui trigram belongs to Metal yet generates Earth (Kun Earth conceals Ren-Gui Water, with Water's growth peak at Shen hour); the Li trigram belongs to Fire yet generates Wood (Xun Wood conceals Geng-Xin Metal, with Metal's growth peak at Si hour); the Zhen trigram belongs to Wood yet generates Earth (Gen Earth conceals Ding-Bing Fire, with Fire's growth peak at Yin hour). Wu-Ji Earth alone resides at the center, flourishing simultaneously in all four seasons, dwelling in the southwest Kun position (where Earth Qi is strongest), with its growth peak at Shen hour. During exhalation, Yang stems move sequentially; during inhalation, Yin stems reverse. The sequential and reverse movements of Yin-Yang, their gathering and dispersing, are all concealed within the completion numbers (seven, six, etc.), which represent the dynamic energy of Heavenly Origin.

When heaven and earth first separated, Yin and Yang each occupied their positions: Heaven divided into Five Qi (the Qi of Five Phases), Earth arranged the Five Phases. The Five Phases established directions, distributed among the four quarters; the Five Qi flowed separately, dispersed among the ten heavenly stems. The celestial spirits shifted positions, mutually combining to generate forms—clearly defined with corresponding pairs, giving rise to the Five Qi of Heavenly Origin that form the true Five Phases. Those cultivating truth must first comprehend the mechanism of heavenly stem rotation, then understand the principles of harmonious generation.

This scripture elucidates the principles of Five Phase mutual generation and harmonization in Daoist Neidan (internal alchemy) practice, and how to cultivate the Golden Elixir through Five Phase regulation.

It first establishes that the foundation of cultivating nature and life (xingming shuangxiu) lies in creating the basis for Five Phase mutual generation. When this foundation is properly established, the Great Dao will naturally manifest. The text then details the process whereby harmonized Five Phases form "True Five Phases":

The Wood phase of the east (represented by celestial stems Jia and Yi) combines with the central Yin Earth (Ji stem) to form "True Earth"; the Metal phase of the west (Geng and Xin) combines with eastern Yi Wood to form "True Metal"; the Fire phase of the south (Bing and Ding) combines with western Xin Metal to form "True Water"; the Water phase of the north (Ren and Gui) combines with southern Ding Fire to form "True Wood"; while the central Earth (Wu and Ji) combines with northern Gui Water to form "True Fire." This cyclical interaction constitutes the fundamental principle of cultivation.

Particular attention is given to explaining the "Wood-Metal obstruction" phenomenon: within the human body, the liver (yanghun, positive ethereal soul) belongs to Wood while the lungs (yinpo, negative corporeal soul) belong to Metal. Normally liver qi should ascend, but because the Metal-phase lungs reside above the Wood-phase liver, the Metal-overcoming-Wood relationship inhibits this upward movement. This resembles how the Zhen trigram (representing Wood) in the east, though structurally composed of one yang line below two yin lines and thus naturally yang-ascending, becomes suppressed by yin forces.

The key to cultivation lies in prolonged practice of the "Zhou Tian Fire Talisman" technique (a Neidan method), through which the Metal nature (Geng Metal) mixed within the liver is refined away, restoring the liver qi to pure Wood nature and enabling its natural ascent. The text concludes by citing Master Lingran's explanation: when liver qi sinks upon entering water, this occurs precisely because of adulterated Metal nature within the liver—Metal's heavy quality causes sinking, while the Wood-Metal mixture manifests as bluish-white coloration.

This scripture primarily elucidates the principles of mutual generation and restraint among metal, wood, water, and fire in Daoist Neidan (internal alchemy) practice. Purple represents metallic nature—metal inherently sinks downward, yet undergoes transformation through fiery refinement. The liver belongs to the wood phase, naturally displaying an upward-floating blue hue; through cultivation, one can stabilize the ethereal soul (hun), embodying the principle of "metal concealed within wood."

The Dui trigram (one of the Eight Trigrams/Bagua) in the western direction corresponds to metal and stores the yin soul (po). Though inherently inclined to sink, it floats upward because Dui—being the youngest daughter of the Qian trigram—contains one yin and two yang lines; the yin cannot subdue the yang, hence the upward movement. When Geng metal (lung metal) combines with Yi wood (liver wood), it resembles a wife following her husband—metal acts as host while wood serves as guest. Through the cyclical fire-times (breath regulation in Neidan) practiced unceasingly for a thousand days, the wood nature within the lungs can be eliminated, allowing pure metal's essence to naturally descend.

The red and white portions within the lungs represent wood nature, which floats when encountering water. Through fiery refinement, they transform into sinking purple, returning to their innate true po, thereby stabilizing the spirit (shen) and extending longevity. In the fiery crucible, the host-guest relationship between metal and wood must be clearly distinguished: removing metal from wood preserves wood's nature by eliminating metallic attributes, while removing wood from metal retains metal's strength by discarding wood's pliancy. Practitioners must comprehend this principle, master the precise degree of fire-times, and properly balance lead and mercury (yin and yang qi)—only then can the Golden Elixir be naturally forged.

Pingshu (likely referring to the Neidan master Zhang Boduan) comments: Nurturing the elixir resembles pregnancy—without proper fire-times, it's like a fetus losing its mother, rendering all effort futile. This parallels how metal and wood require fire to distinguish their host-guest relationship. The concluding reference to "water and fire's completion and incompletion" points to the hexagrams in the Yijing where water and fire interact: the Jiji hexagram signifies accomplishment, while Weiji indicates unfinished business—hinting that cultivation requires mastering the fire-times of yin-yang harmonization.

Water and fire inherently contain and nurture each other—water holds fire within it, and fire holds water within it.

Why does water contain fire? Because water corresponds to the Kan trigram (one of the Eight Trigrams, symbolizing water) in the north, representing yang within yin. Water reflects objects, and this reflective capacity is the true fire latent within water. In the human body's five organs, water corresponds to the kidneys, which store Jing (essence), and Jing is the manifestation of fire.

Why does fire contain water? Because fire corresponds to the Li trigram (one of the Eight Trigrams, symbolizing fire) in the south, representing yin within yang. The core of a flame appears black, which is the true water latent within fire. In the five organs, fire corresponds to the heart, which governs blood, and blood is the manifestation of water. The Book of Changes states that "water above fire" forms the Ji Ji hexagram (symbolizing harmonious union), while "fire above water" forms the Wei Ji hexagram (symbolizing disharmony). Master Ping (a Neidan practitioner) explains: Water gathers the Samadhi True Fire, while fire refines true water through tempering. Practitioners must follow this natural principle to harmonize yin and yang. The key lies in subtle transformation, allowing water and fire to ascend and descend in mutual integration, just as the Ji Ji and Wei Ji hexagrams transform into each other. This naturally enables the congealing of lead and mercury (Neidan terms symbolizing yin and yang qi) in the Dantian, and when the Golden Elixir is perfected, golden light fills the chamber.

The ascending and descending movements of water and fire rely on the role of earth. The Book of Changes states that water flows downward to moisten, while fire rises to dry—this is the unconscious resonance of nature. Though water's nature is to descend and moisten, and fire's nature is to ascend and blaze, why does the Ji Ji hexagram place water above fire? Because Kan water contains fire (the Kan trigram absorbs the yang of Wu earth), allowing the clear and light Jing qi to rise and transform into true water. Li fire contains water (the Li trigram absorbs the yin of Ji earth), enabling the heavy and turbid blood qi to descend and transform into true fire. What we call water and fire are, in truth, the genuine qi born from the primordial qi of heaven and earth, originating from the spleen. The spleen spirit governs creation, residing at the center and overseeing the four directions, driving the qi's upward and downward movements with each breath. The primordial qi of heaven and earth moves in harmony with the Five Phases in each inhalation and exhalation. The Book of Changes speaks of heaven's number five and earth's number six—these are the balancing numbers of yin and yang, referring to earth. The Cantong Qi states that earth flourishes in all seasons, permeating everything, while the four colors—green, red, white, and black—each occupy their directions, with the central palace relying entirely on the function of Wu and Ji earth. Master Ping also notes that the Four Symbols and Five Phases all depend on earth. Without the harmonizing qi of Wu and Ji earth to regulate the ascent and descent in the Kan and Li trigrams, the divine elixir can never be perfected.

Regarding how the mercury (symbolizing the original spirit) hidden in the heart and the lead (symbolizing the original essence) concealed in the kidneys are employed: the five organs...

This passage elucidates the Daoist Neidan (internal alchemy) practice of "reversal technique" and the mysteries of Qi circulation within the human body. Practitioners achieve Yin-Yang equilibrium by regulating breath and intention to facilitate the mutual transformation between water and fire (representing the dual energies of Yin and Yang).

Specifically, when the primordial Qi from the kidneys (represented by the Kan trigram) activates, the Yang energy of Wu-earth flows with exhalation. When the primordial Qi from the heart (represented by the Li trigram) activates, the Yin energy of Ji-earth flows with inhalation. These dual energies each possess Five Phase attributes, combining to form the complete numerical principle of "nine heavens and ten earths." Through refining mercury (representing Shen/spirit) from the heart and extracting lead (representing kidney Qi) from the kidneys, the Jing (essence) and Qi coalesce into the "knife-shaped measure" (a Neidan term denoting the embryonic form of elixir).

When mental clarity is achieved, it resembles the Li trigram shedding its Yin line to become the purely Yang Qian trigram—maintaining this state naturally dissolves emotional attachments. When kidney Qi becomes abundant, it mirrors the Kan trigram shedding its Yang line to become the purely Yin Kun trigram, enabling a state of crystal-clear consciousness.

The text then cites the perspective of Guangchengzi (legendary teacher of the Yellow Emperor): the human body mirrors the cosmos, with the head corresponding to heaven. Just as the Big Dipper revolves around Polaris, the seven orifices ("seven administrators") must operate in harmony. The ears correspond to the stars of Greedy Wolf and Giant Gate, requiring purity; the eyes relate to the stars of Storehouse and Cultural Curve, needing measured opening and closing to preserve spiritual vitality; the nose (associated with Pure and Military stars) serves as the gateway connecting to the Mysterious Feminine (Dantian), requiring continuous, subtle breath regulation. Finally, practitioners must guard the lower Dantian ("golden pass and earthly door") to prevent essence leakage, thereby stoking the inner true fire to achieve the alchemical state of "water and fire in perfect balance."

The entire cultivation process emphasizes harmonizing and transforming the body's Yin-Yang energies through breath control and intentional guidance, ultimately coalescing into the internal elixir. Practitioners must precisely time these processes and harmonize the five viscera's spiritual functions to attain the perfected state of fully formed elixir with perfected firing times.

The primordial Qi (Yuanqi) in the human body flows through the three Dantian (energy centers): the upper Dantian (between the eyebrows), middle Dantian (solar plexus), and lower Dantian (below the navel), mirroring how the Bagua (Eight Trigrams) permeates the entire body. The Crimson Palace (what Daoism calls the heart) serves as the convergence point of Yin-Yang, where Jia Wood (Yang) meets Ji Earth (Yin), creating the dynamic interplay between Tiger (Metal) and Dragon (Wood). This sacred space functions as the hall where all spirits reside.

The kidneys (corresponding to the Kan trigram) secretly harbor both Yin and Yang Qi, capable of gathering the Five Phases (Wood, Fire, Earth, Metal, Water) and harmonizing the Four Symbols (Azure Dragon, White Tiger, Vermilion Bird, Black Tortoise). When Jing (essence), Qi (vital energy), and Shen (spirit) coalesce into radiant light, and Wu Earth and Gui Water return to their root, the Palace of the Supreme One (the Dantian) takes form. The lungs store the Po (corporeal soul, associated with Ding Fire), and when settled, they remain undisturbed. The liver houses the Hun (ethereal soul, linked to Geng Metal), and when free from emotional turmoil, it maintains perpetual serenity.

The large intestine (Ren Water and Jia Wood) governs transmission, while the gallbladder (Xun trigram, Xin Metal) preserves emotional equilibrium. The spleen and stomach (Kun Earth) function like the meandering Qu River, cycling endlessly to nourish Yin and Yang. Kidney Yang (Gen Mountain) generates the source of water, transforming into pure and refined Qi. These seven organ functions correspond to the Bagua, embodying the foundation of Yin-Yang and the profound mystery of refining the Golden Elixir (Neidan practice, the cultivation of Jing, Qi, and Shen).

The Yinfu Jing states: When the Seven Administrations (the functions of the five viscera and six bowels) operate in harmony, "Yellow Sprouts" (the nascent Yang energy in Neidan) emerge within the body. When the Bagua circulates throughout the body, the divine light turns inward, becoming subtle and restrained. The Yijing also teaches: The sages used trigrams to reveal profound truths and established the Bagua to exhaustively explore the principles of all things.

This scripture primarily elucidates the dynamic interaction between "Wood" and "Metal" in Daoist Neidan (internal alchemy) practice. "Wood" represents the liver's Hun (ethereal soul) with its attributes of benevolence and pliability, while "Metal" embodies the lungs' Po (corporeal soul) with qualities of firmness and rigidity. The practitioner must harmonize these two complementary yet opposing energies.

The first passage describes the fusion process of Wood and Metal: Wood's gentle benevolence and Metal's unyielding nature repeatedly rise and submerge. Through cultivation, one extracts Metal from Wood until Metal dissolves and Wood vanishes—ultimately allowing the refined soul to wander the void, entering meditative absorption. In this state, the Hun and Po stabilize (with Hun dominant and Po subdued), commanding reverence even from spirits and deities.

The second passage employs the imagery of "Zhen trigram concealing Geng Metal" to symbolize yin-yang union. Like thunder (Zhen's elemental association) harboring metallic essence, the coupling of Yi Wood (yin Wood) and Geng Metal (yang Metal) resembles thunderclaps with lightning—a dragon's roar meeting a tiger's roar. Practitioners must maintain clarity amidst misty rain, hiding their true nature like an eternal flame in Mount Min, ultimately attaining the undifferentiated state of pure yang.

The third passage continues exploring Wood-Metal harmonization: Tender Yi Wood deeply embraces steadfast Geng Metal, creating musical harmony. The "wooden man clapping hands" and "stone maiden playing the qin" symbolize yin-yang interplay. Through refinement, the two energies interpenetrate, tempered by alchemical fire until one recognizes the true self.

Subsequent passages detail the cultivated states of "Wood yielding to Metal" and "Metal dissolving Wood": Either Wood recedes as golden light emerges, or metallic firmness dominates while wooden pliability submits. Both require guidance by the true fire (Neidan's firing process) to restore host and guest to their proper positions, transcending worldly attachments.

The final passage discusses "water and fire complementing": The Kan trigram (Water) contains a single yang line—its nature inherently pure. When the true fire (heart fire) reaches fullness and merges with kidney water (Kan Water), it generates misty vapor. At this stage, the spirit's power awakens; the alchemical "medicine" completes its refinement, exuding fragrance like orchids in bloom.

The Huizhen Ji elucidates the core principle of water-fire interaction and the union of Kan (Water) and Li (Fire) in Neidan (internal alchemy) practice. Through harmonizing the yin and yang energies (Kan-Water and Li-Fire) within the body, the adept refines Jing (essence), Qi (vital energy), and Shen (spirit) into the Golden Elixir.

The first passage depicts the inner landscape during cultivation: The heart fire (six yin lines) blazes like burning coal, while the kidney water (true water) remains clear and cold as ice. These two forces circulate through the mediation of the Central Palace (Yellow Court, representing Earth). When yin and yang energies unite, they produce thunderous vibrations, with the Big Dipper manifesting amidst swirling mist—signifying the microcosm of the human body merging with the macrocosm. The practitioner's mind becomes empty as ashes yet encompasses the entire cosmos.

The second passage emphasizes the pivotal role of Earth (spleen intention, represented by Wu-Ji). Through breath regulation, the yin and yang energies—symbolized by silver-lead and cinnabar-mercury (Neidan terms for vital essences)—circulate and transform within the Yellow Court (Dantian). When the true yin within Li-Fire (heart fire) combines with the true yang within Kan-Water (kidney water), the physical form (Kun-body) achieves pure yang perfection, forging the elixir of immortality (internal alchemy) that transcends ordinary existence.

The third passage allegorically describes the alchemical process: The water palace (kidneys) and fire cage (heart) resemble a mist-enshrouded lunar palace where qi dynamics shift like wind. The Central Yellow Court coalesces into the "knife-and-square" (prototype of the elixir), revealing the yang within Kan (true yang of the kidneys). From this stillness emerges primordial qi (primal true energy), ultimately crystallizing as jade frost (the internal elixir) within the alchemical furnace (lower Dantian).

The final sections employ the Seven Stars of the Big Dipper as symbolic representations of cultivation elements. The union of the Wolf Star (symbolizing original spirit) and Gate Star (symbolizing original qi) penetrates the five aggregates (form, sensation, perception, mental formations, consciousness). The Fortune and Literary Stars (representing consciousness) must withdraw their outward radiance, allowing the immortal child (true intention) in the Hall of Light (upper Dantian) to capture the true yang (primordial qi), achieving a state of cosmic integration. Ultimately, the practitioner attains the freedom of the Northern Dipper's pivot, dwelling in companionship with the bright moon.

These poems from the Huizhen Ji (Anthology of Meeting the True) employ symbolic language to describe the process of Neidan (internal alchemy) cultivation. The first poem, "Drunk in Peach Blossom Spring," elucidates the essentials of breath regulation during practice: in stillness, one's breathing should become as subtle and enduring as the earth's deepest energies, maintaining perfect rhythm. Through breath control, the practitioner stabilizes the Shen (spirit), much like maintaining the ideal temperature in an alchemical furnace. The crux lies in guarding the lower Dantian (elixir field) - the Mysterious Feminine Gate - which represents the root of vital energy.

The second poem, "Drunken Decline," depicts the dynamic interplay of Yin-Yang energies within the body. These primal forces intertwine according to the transformative patterns of the Bagua (Eight Trigrams) hexagrams. Practitioners must harmonize these energies through natural respiratory rhythms, where inhalation and exhalation mirror cosmic cycles. Upon reaching advanced stages, one's internal Qi (vital energy) becomes vast as the ocean, while consciousness attains crystalline clarity.

"Magnolia Blossom Slow" employs the Kun (Earth) hexagram as metaphor for the "empty valley" state in cultivation. Representing the receptive earth that nurtures all things, this hexagram teaches practitioners to maintain profound stillness, allowing internal energies to circulate naturally. Through coordinated breath and intention, Qi flows through the Governing and Conception vessels, ultimately realizing the dual cultivation of nature and life (Xingming Shuangxiu).

The final "Magnolia Blossom Slow" uses the Qian (Heaven) hexagram to symbolize the pinnacle of alchemical achievement. Embodying celestial purity and dynamic vigor, this stage manifests as primordial Qi expanding like the boundless sky, culminating in the union of heaven and humanity. At this transcendent juncture, the practitioner undergoes qualitative transformation of body and mind, surpassing ordinary human limitations.

All things in heaven and earth are arranged according to natural laws, with the harmonious progression of four seasons. The Dao (the Way) is supremely simple yet permeates everything. Once the mechanism of cosmic operation is set in motion, it continues endlessly—the rising and setting of sun and moon are all manifestations of Qi (vital energy) in motion.

The stars are arrayed in orderly patterns, cycling through the vast void. Their nature is light and pure, their transformations unfathomable. Within the profound mystery of the Dao lies subtle truth, nurturing the foundation of life. The light of innate nature merges with the Great Void (cosmic origin), revealing majestic visions and attaining complete liberation in the realm of true suchness—a mystery beyond words.

First Poem of "Wind Through Pines":

The Qian and Kun hexagrams (symbolizing heaven and earth) form a ladder to the skies, with firm and yielding lines alternating in height. Through the changes of six lines, we deduce celestial patterns, like turning an armillary sphere to track the sun and moon. Skillfully gathering heaven-earth essences transforms them into jade nectar; through breath regulation, we ingest the knife-guide (minute elixir). Gold and water mingle, flowing through Caoxi (symbolizing meridians), and after nine cycles of refinement, the elixir body is perfected. Its fragrance scatters on the wind, delighting even the Wooden Boy (inner spirit). Attaining immortality reveals primordial Yang Qi—a broad mind like a rainbow spanning the sky.

Second Poem of "Wind Through Pines":

Heaven-earth's order is like the cords of a great net; the Big Dipper's rotation guides the stars. Following waxing and waning of Yin-Yang, fortune and decline alternate in celestial cycles. Guard Kan and Li (water and fire in balance) with care—only then can the elixir open the Mysterious Feminine (life's origin), merging with the realm of Xiyi (tranquil non-action). In profound mystery, enter Wuwei (non-action), awaiting the convergence of Jing (essence), Qi, and Shen (spirit). Refine according to the hours, follow fire phases strictly, until the golden elixir shines complete—revealing sacred transformations that penetrate heaven-earth, manifesting majestic forms beyond the body.

Third Poem of "Wind Through Pines":

The changing lines of Qian and Kun conceal heaven's heart—simple pivots hold truths of rise and fall. Through ascent and descent, sweet dew forms, nurturing Yellow Sprouts (primordial Qi) that take deep root. Golden flowers flourish brilliantly; elixir radiance illuminates, revered by ten thousand spirits. When clouds clear and skies calm, it's like drinking fine wine, with celestial music in the ears. Intoxicated, dance upon the wind, singing freely with clapped rhythms. Enter the pure stillness of grotto-heavens, finding true joy like meeting kindred souls.

Fourth Poem of "Wind Through Pines":

Yin-Yang lines open heaven-earth; the single Qi surges upward. Through movement, stillness, rise, and fall, grasp the roots of floating and sinking. Nourish the Valley Spirit (primordial Shen) for eternal life—crucial is sealing the Duikou (guarding speech). The Seven Stars circle Kunlun (crown Dantian); discernment is needed. Persist in Wuwei daily, until golden light manifests. Skillfully condense essence into jade dew; through mystical practice, attain the pure Yang body.

This passage depicts the mystical visions encountered during Daoist Neidan (internal alchemy) practice. The first paragraph describes the circulation of vital Qi within the practitioner's body: Jade-like essences (Qiongying) surge like a fountain, their fragrant forms interweaving with radiant clouds while celestial harmonies resound clearly. Within this seemingly void creation, true mechanisms manifest as the yang energy of the Xu Huang (personified Dao) moves freely through the Dharma realm (meditative states), displaying miraculous transformations that remain seamlessly unified.

The second section illustrates the alchemical process: Heaven and Earth become like a boiling cauldron refining the divine elixir. The Tiger (kidney yang) converges with the Dragon (heart yin) like a toad mating with a phoenix. Auspicious Qi fills the emptiness as sweet dew (inner alchemical term for saliva) overflows. Through this refining process emerges golden nectar (refined vital essence), exuding fragrance surpassing that of pepper and orchids. After drinking this jade liquor, one rides phoenixes in ecstatic dance, revealing transcendent grace amidst clear winds and bright moonlight.

The third passage portrays yin-yang transformations: Heaven and Earth divide into spring and autumn seasons as yang's nine and yin's six numbers alternate. Rising yang energy regenerates yin while primordial Qi nourishes the spiritual terrace (upper Dantian). Firmness and yielding balance perfectly, advance and retreat follow proper measure, ultimately returning to pure stillness. Those who attain the true Dao experience jade nectar (inner elixir) flowing through channels like irrigation ditches, with all meridians unobstructed. The sovereign (mind) rests peacefully while the people (internal organs) prosper, wandering freely in the divine continent (microcosmic body). Such wuwei (non-action) perfection surpasses even Heaven and Earth's creative power.

The fourth section discusses yao transformations (yin-yang changes): Heaven's yang and Earth's yin energies intertwine, governing creation's mechanisms. The interplay of firmness and yielding generates all things in harmony with celestial cycles. Sun and moon's yin-yang pairing concentrates in the Wu chamber (middle Dantian) to form the rounded elixir seed. These dual energies nurture the jade field (Dantian), producing inner elixirs pure as jade and snow. Attaining the way of longevity, one becomes like Caoxi's waters (symbolizing the essential path) reaching all seas, comprehending supreme meditation principles.

The fifth paragraph describes alchemical firing times: Heaven and Earth's rotation produces Xuanhuang Qi (primordial chaos energy), regulating yin-yang's advance and retreat. Creation's numbers accord with celestial firing phases as clear breezes turn the Heavenly Pivot (Big Dipper, representing internal Qi movement). Simplicity reveals the dance of floating and sinking, while breath incubates jade nectar. Immortal youths (symbolizing vital energy) raise cups in musical celebration, their songs and dances lingering gracefully. Slightly intoxicated beneath bright moonlight, they laugh proudly with honored guests (internal deities) in the Yellow Court, subduing all demons (distracting thoughts) to enter refreshing clarity.

The sixth section elucidates golden elixir essentials: Refining heaven-earth's essence into yang spirit through the alchemy of Li (heart fire) and Kan (kidney water). Through nine returns and seven reversals (internal alchemical cycles), the harmonious interplay of yin-yang energies circulates naturally. Sun and moon (yin-yang) illuminate the entire chamber as their union generates jade blossoms (inner elixir). The perfected elixir remains eternally tranquil and upright, brimming with vast clear Qi. The inner true spirit reveals its original face—this state of perfect clarity transcends cosmic laws, embodying absolute freedom.

This scripture elucidates the four crucial stages of Daoist Neidan (internal alchemy) cultivation—symbolized by the hexagrams Fu (Return), Lin (Approach), Tai (Peace), and Dazhuang (Great Strength)—using cosmological imagery to depict the transformative process of body and mind.

The first stage, corresponding to the Fu hexagram, portrays the initial emergence of Yang energy. Like underground springs stirring at the winter solstice (marked by the "Yellow Bell tuning pitch," a seasonal reference), the practitioner's vital Qi (Huangzhong yinglü) begins to awaken. Through regulated breathing ("softening the breath into subtle continuity"), the dual forces of Yin and Yang (symbolized by lead and mercury, representing Jing, Qi, and Shen) harmonize, eventually coalescing into the elixir within the Dantian (spiritual crucible). While initial results may appear within a hundred days, the practitioner must learn timely restraint (as hinted by the "completed ninth line yielding to the sixth").

The second stage, aligned with the Lin hexagram, signifies the gradual flourishing of Yang energy. Mirroring the earth's rising vitality in spring, the practitioner's Qi ascends along the Governing Vessel (metaphorically described as the "Yellow River's converging waters," representing the Du and Ren meridians). Guided by specialized breathing techniques ("mystically circulating the Jade Nectar"), the Qi circulates, demanding particular vigilance against distractions ("not releasing the Three Corpses' spirits" refers to subduing desires). When the Qi fully saturates the Dantian ("the great capital where dragons leap"), this phase culminates.

The third stage, embodied by the Tai hexagram, reflects the harmonious interplay of Heaven and Earth's Yin-Yang forces. Within the practitioner, the White Tiger (lung Qi) and Azure Dragon (liver Qi) harmonize, generating mist-like vital energy. Here, body and mind enter bliss ("serenely immersed in celestial joy"), the physical form is deeply nourished, and a state of tranquil Wuwei (non-action) is achieved ("all worldly attachments swept away for eons").

The final stage, represented by the Dazhuang hexagram, marks the zenith of Yang energy—like thunder shaking the heavens. The practitioner's Qi becomes supremely abundant ("gentle winds arise"), the spirit intensely concentrated ("the ethereal soul solidifies in radiance"), and all malevolent thoughts vanish ("the corporeal soul disperses, demons cease"). The body and mind attain a refreshing liberation, reaching the ultimate state of "spiritual perfection and joyful communion with the Dao."

The text employs specialized Daoist terminology: "knife and spoon" (Daoist alchemical substances), "River Chariot" (Qi circulation), "Cao Stream" (the Ren meridian), and "clay ox" (vital energy)—all metaphorical references to Neidan practice. These four hexagrams correspond to progressive stages of cultivation, embodying the Daoist ideal of "reversing the ordinary to attain immortality."

This scripture describes the various states and experiences encountered during Daoist Neidan (internal alchemy) practice. The opening reference to "blossoming heart flowers" metaphorically depicts the practitioner's purified mind, where the true nature emerges upon reaching profound understanding of cosmic principles. "The dissipation of amorous desires" signifies the cessation of carnal passions as the Five Qi (energies of the five organs) circulate vigorously within the body, continuously performing their divine work day and night.

Transcending worldly dust, the adept attains the immortal path, standing aloof like flowers blooming atop a wall. The imagery of "leaping flying dragons" symbolizes the rising Yang energy ascending to the Muddy Pellet Palace (upper Dantian) at the crown, connecting with heaven and earth. Within the practitioner's body, Yin and Yang energies intermingle and transform, creating a misty vapor that fortifies the physique like golden axles, enabling free flight to the Penglai fairy mountains.

The passage about "the zenith of the celestial dome" describes Yang energy reaching its apex as the practitioner ascends Mount Kunlun (sacred Daoist mountain), harmonizing Yin-Yang to stabilize and circulate the vital essence (symbolized by mercury). The revolving "jade dragon" (representing genuine Qi) moves with cloud-and-thunder swiftness, crystallizing into jade pearls and golden grains (the internal elixir). Returning to original purity, the adept dispels distractions ("expelling the white, retaining the blue") to attain unwavering stillness.

The "heaven-earth interaction" section explains the harmonious union of Yin-Yang, where the celestial life force (Tian Gui) returns to its source. Riding dragons through the cosmos, the practitioner experiences true joy and bliss. Through concentrated serenity, the light of innate nature blazes forth, transcending the Three Realms to reach the state where self and objects are forgotten.

Finally, the "great vision of wind and earth" portrays the practitioner with purified senses, manifesting primordial nature as brilliantly as rainbows. After refining spirit to merge with Dao, the dharma body moves effortlessly with emptiness, responding infinitely to changes. The white ox (symbolizing pure Yang energy) crosses the heavenly river as the true self vanishes without trace. Form and shadow both dissolved, the adept roams alone with the freedom of breeze and moonlight, ultimately achieving the perfected state where a single river sand contains the entire cosmos.

This passage describes the process of Neidan (internal alchemy) cultivation in Daoism, using symbolic language to depict the harmonious interaction of Yin-Yang and the coagulation of the Golden Elixir.

The first section, "Flowers tumbling on the wall," speaks of the practitioner reaching a state where self and objects are both forgotten. Like peeling away layers to reveal crystalline true nature, when all worldly distractions are eliminated, one beholds the pure luminous true self. At this stage, the practitioner's Shen (spirit) can penetrate heaven and earth ("three heavens" refers to the Three Pure Ones' realms, "nine earths" to the underworld domains), achieving serene mental equilibrium. This state neither increases nor decreases—it is perfectly balanced, ultimately merging with emptiness to manifest the sublime realm of the Dao.

The second section, "Kun returns to its origin," describes the harmonization of Yin-Yang. Kun (the Yin principle) returns to its source while Qian (the Yang principle) manifests its true position—the two Qi (energies) separate and reunite. The practitioner attains awakened consciousness that is neither empty nor existent, with all boundaries between self and objects dissolving into primordial chaos ("Xiyi" refers to the Daoist void state). Here the Golden Elixir takes form, transcending the cycles of life and death.

The subsequent "Ninefold Yang Elixir Advances the Way," composed in the style of a truncated Magnolia Flower poem, details the alchemical process:

On the first day, cultivation resembles thunder and wind (Zhen trigram representing thunder, Xun trigram representing wind)—the furnace fire blazes fiercely until the Golden Crow (symbolizing the sun) returns to the Cassia Palace (moon palace, indicating Yin-Yang harmony).

On the second day, lead (representing Yuanjing, original essence) and mercury (representing Yuanshen, original spirit) blend within the cauldron (Kan trigram for water, Li trigram for fire)—like a divine turtle emerging from the sea in dazzling colors.

On the third day, mountains and marshes exchange breath (Gen trigram for mountain, Dui trigram for marsh)—the furnace fire blooms like a lotus.

On the fourth day, heaven and earth unite harmoniously (Qian trigram for heaven, Kun trigram for earth)—the six directions (space) and three powers (heaven-earth-humanity) become complete. The Golden Elixir is finally forged, and the practitioner achieves the state of cosmic unity.

This scripture describes the nine stages of Daoist Neidan (internal alchemy) practice, each corresponding to different phases of Yin-Yang interaction and cultivation states. The text employs rich symbolic language to express the energetic transformations during practice.

The first stage (5th day) depicts the union of Xun (Wind) and Zhen (Thunder). It describes spring waters nourishing valley trees, symbolizing the flow of Jing (essence) and Qi (vital energy) within the body. Practitioners at this stage experience clouds and thunder harmonizing—their internal energy becomes luminous like moonlight flowing through the meridians.

The second stage (6th day) illustrates the interaction between Li (Fire) and Kan (Water). Using alchemical metaphors, it describes how repeated refinement purifies internal energy until it becomes jade-like in purity. The practitioner perceives radiant light filling the Dantian (energy center), maintaining vigorous Shen (spirit) while emitting subtle fragrance from the body.

The third stage (7th day) presents the union of Dui (Lake) and Gen (Mountain). It describes the condensation of essential substances within, akin to the arrival of Tiankui (primordial essence). After seven refinement cycles, the Golden Elixir manifests with auroral light—the mind stabilizes, afflictions dissolve, and consciousness becomes limpid as the full moon.

The fourth stage (8th day) shows the perfect harmony of Kun (Earth) and Qian (Heaven). Here Yin-Yang achieves perfect equilibrium as the Bagua (Eight Trigrams) cycles naturally. The practitioner enters unity with cosmic forces—pure Yang Qi crystallizes within, granting bodily lightness and extraordinary fragrance.

The final passage reveals the consummate state of cultivation. After nine refinement cycles culminating in "nine returning to one," the Golden Elixir is perfected. Returning to primordial origins, golden light permeates the body, filling the chamber with celestial fragrance. This represents the ultimate achievement—returning to the source and merging with the Dao.

This scripture elucidates three crucial stages of Daoist cultivation: "Ninefold Transformation to Completion," "Refining Spirit to Merge with the Dao," and "The Great Ocean of Perfect Enlightenment."

The "Ninefold Transformation to Completion" section describes achieving primordial purity through repeated refinement (numbers like seven returns, three-times-three, and nine-times-nine symbolize cyclical cultivation). Practitioners must silently harmonize with true essence, uniting Jing (essence), Qi (vital energy), and Shen (spirit) into an enduring unity. Regardless of external changes, adepts maintain their fundamental nature, attaining indestructible permanence.

"Refining Spirit to Merge with the Dao" employs two poetic verses: The first depicts the transformative interplay of Yin-Yang energies (Taiyin representing lunar Yin, pure Qian symbolizing solar Yang), urging transcendence of worldly forms to return to original authenticity. The second verse portrays the Yang soul (original spirit) soaring beyond physical constraints, surpassing life-death dichotomies and worldly attachments to manifest its true form—a state of formless perfection brimming with subtle function.

"The Great Ocean of Perfect Enlightenment" depicts the supreme realm: like an boundless sea of awakened wisdom where luminous pearls of insight emerge. This paradoxical state simultaneously encompasses all existence yet remains utterly empty ("presence within absence, absence within presence"), transcending movement and stillness to reveal everywhere the radiant original nature. Unchanging (neither increasing nor decreasing), it embraces all phenomena (containing the ten thousand things), permeating all dimensions of space-time (filling the four seas and three temporal realms), ultimately returning to the deathless primordial source.

Technical terms explained: "Seven Returns" (qifan) and "Nine Restorations" (jiuhuan) denote alchemical cycles of refinement; "Huaxu" refers to the Daoist utopian paradise; "Ocean of Perfect Enlightenment" (yuanjue hai)—originally a Buddhist concept—demonstrates the characteristic Three Teachings syncretism during Song-Yuan period Daoist practice.

This passage elucidates the profound states and concrete methods of Daoist Neidan (internal alchemy) practice.

The first section describes the supreme state of unity between the practitioner and the Dao. The adept's form merges with the profound mystery of the Dao, manifesting boundless dharma appearances. Upon realizing eternal truth, the luminous function surpasses all worldly treasures (the legendary pearl of the Black Dragon), shining alone in the depths. True sages can penetrate mountains and walls, displaying majestic presence—equally capable of descending into earth and ascending to heaven in endless transformations. When spiritual powers reach their zenith, they become like a full moon: radiant, complete, pure and transparent yet elusive. This state is crystal clear, characterized by Wuwei (non-action) and formlessness, transcending measurements of height or distance—neither emptiness nor form, revealing the originally pure causes and conditions. The entire cosmos presents no obstruction; enlightenment of the "square-inch heart" (the Dantian) encompasses heaven and earth. Ultimately achieving perfect, unobstructed realization—neither separate from all phenomena nor attached to them—vast and magnificent, transcendent yet at ease, with wisdom illuminating all realms. Upon awakening to this supreme truth, one masters mysterious authority, transcends past and present, and accomplishes formless merit.

The second section explains the relationship between the generative and completion numbers of the Five Phases (Wood, Fire, Earth, Metal, Water), a crucial theory in Neidan practice. The Five Phase energies converge at the Mysterious Feminine (the Dantian), while the Valley Spirit (the body's primordial Qi) follows the natural rhythm of breathing. Respiration should be smooth and prolonged, harmonizing the protective and nutritive Qi (blood and energy) to balance the meridians. When "fire timing" (the regulation of cultivation intensity) reaches perfect equilibrium, the vital energy naturally becomes abundant, permeating all bones and joints, opening the nine orifices, with breath circulating freely between upper and lower regions. When practice aligns with cosmic rhythms, Yin-Yang achieves equilibrium, vital energy rises and descends orderly, hardness and softness complement each other, and regulated breathing follows natural patterns—ultimately refining a single divine elixir. This elixir can transform the Yang spirit, manifesting boundless dharma realms and enabling cloud-riding flight.

The third section details the transformative process of Golden Elixir refinement. The mystery of the Golden Elixir lies in the "advancing fire" technique (regulating breath and intention), requiring precise adjustments. The unbroken breath must synchronize with celestial movements, utilizing the "cauldron and furnace" (the body) and "lead and mercury" (spirit and energy). Drawing down the Golden Crow (solar essence) and Rainbow Phoenix (lunar essence), they unite in the Yellow Court (middle Dantian) where Yin and Yang energies meet and merge. At advanced stages, visions appear—the Moon Maiden (lunar fairy) presenting wine, immortal music playing ceaselessly, and celestial youths dancing upon clouds. Finally, the perfected Golden Elixir radiates five-colored light, with the nine-times refined elixir becoming supremely precious.

The fourth section continues with the completion stage of elixir refinement. One must study the methods of advancing and retreating fire, practicing during the "six Yang" periods (peak Yang energy hours). When the Dragon and Tiger (mind and kidney energy) unite, pure breezes swirl as Yin and Yang energies combine with exquisite precision, resonating like thunder through the cosmos. The spiritual medicine (jade stamens and divine mushrooms) manifests—when the "medicine cauldron" (Dantian) reaches perfect fire timing and the "ice congeals while fire cools," it refines into snow-pure immortal flesh.

This scripture describes the process and states of attainment in Daoist Neidan (internal alchemy) practice, using poetic language to depict the wondrous experiences of an adept through "drinking the knife-guǐ" (ingesting the inner elixir).

The first passage portrays the practitioner's body emitting extraordinary fragrances and radiating golden light, illuminating the night as bright as day. This illustrates the physiological transformations that occur when Neidan cultivation reaches an advanced stage. "Chōngxū dé mào" (flourishing virtue in soaring emptiness) refers to the practitioner attaining a state of perfect void, where virtue is complete, purity is flawless, and the distinctions between form and emptiness are transcended—both the hún (ethereal soul) and pò (corporeal soul) are sublimated.

The repeated mention of "drinking the knife-guǐ" in subsequent passages signifies ingesting the inner elixir. The practitioner regulates breathing (wù-jǐ refers to respiration) to harmonize the ascent and descent of Yin and Yang energies (lí-kǎn, representing fire and water), refining the elixir within the Dantian (energy center). After consuming the elixir, miraculous experiences arise: soaring to the lunar palace, beholding the jade rabbit (symbolizing the moon), and manifesting rainbows and other celestial phenomena. It also mentions the "fire date" (another name for the inner elixir) being carried by the jade youth (symbolizing the body's true Qi).

The scripture further describes the mental and physical state during cultivation: the "heart-monkey and mind-horse" (restless thoughts) must be tightly restrained, maintaining harmonious Qi circulation; one must cultivate in silent obscurity, allowing Yin and Yang energies to merge; and expansive Qi must flow freely to stabilize the spirit. Ultimately, one attains the serene and empty state of "condensed dew's chill" and "the moon's empty splendor," even "steadily treading the path of clouds and mist"—a metaphor for the ability to traverse the heavens.

The final passage, "cultivating truth, severing all ties," emphasizes the necessity of relinquishing worldly attachments, forging an iron will, and cutting off distracting thoughts (the "horse and monkey" symbolize the restless mind), so that the "four elements" (earth, water, fire, and wind—representing the body) may rest in ease. This serves as a summation of the mental discipline required in Neidan practice.

This scripture elucidates the essential principles of Daoist Neidan (internal alchemy) cultivation, outlining several progressive stages of practice:

The initial stage describes how practitioners must gather their scattered Shen (spirit) to achieve a state of unified stillness throughout all bodily orifices and internal organs. When the Qi (vital energy) flows unimpeded within, the "ten thousand spirits" (referring to consciousness permeating every part of the body) experience profound joy. At this stage, breathing becomes as subtle as a tortoise's respiration, reaching a mysterious and penetrating state. Practitioners must maintain crystal-clear mental clarity, enabling the primordial Qi (the "mother") and postnatal Jing (essence, the "child") to intermingle, allowing the natural harmonization of Yin-Yang energies. When Yang energy manifests and the Golden Elixir is forged, one attains the ability to traverse realms freely—a state requiring mind as pure as ice and snow.

The text then reveals that authentic Daoist practice must transcend material attachments, appearing complete yet maintaining humility. When the radiance of one's true nature ("the moon of innate nature") fully emerges, it connects heaven and earth. It criticizes those who blindly pursue mystical states without grasping fundamentals—practitioners obsessed with formal sitting meditation ("false sitting") who consequently lose their original heart-mind. Emphasis is placed on mastering the ascending and descending Qi movements among the Three Dantian (three palaces), warning that fixation on any single location causes loss of true essence.

Subsequent passages detail breathing techniques: respiration must synchronize with the operations of the "valley spirit" (Dantian) to create an unbroken flow of Qi. Disrupted breathing violates natural rhythms, preventing Qi from returning to its source. Common cultivation errors include rigid adherence to singular methods, Qi dissipation, and physical restlessness. Proper practice fills the Primordial Palace (Dantian) with vast righteous Qi, penetrating the Three Passes (coccyx, thoracic spine, and jade pillow) until the distinction between self and objects dissolves.

The conclusion warns against allowing limb Qi to scatter, which generates illusory visions ("empty flowers"). Authentic cultivation requires returning Shen and Qi to their roots to reveal sagely accomplishments. Throughout the text, the philosophy of "dual cultivation of nature and life" (Xingming Shuangxiu) permeates, emphasizing body-spirit unity, Yin-Yang balance, and the Wuwei (non-action) approach to the Dao.

This passage is a Daoist cultivation poem describing the practitioner's journey of Neidan (internal alchemy) practice toward transcendence. Here's a modern interpretation of its core concepts:

When practitioners harbor deluded thoughts without awareness, it's like boasting while suffering from spiritual sickness. True cultivation requires understanding the boundless nature of all phenomena. But when worldly dust clouds one's vision of the Dao, one falls into illusory demonic realms, disrupting the Yin-Yang balance. At this stage, refining the inner elixir (symbolized by jade sand) becomes essential for harmonization.

During practice, maintain a mind pure as snow, untainted by worldly defilements. Beneath an outwardly simple appearance lies inner serenity. When the primordial Qi (Yiqi) harmonizes within, the spirit enters a blissful state akin to mild intoxication, as if golden youths and jade maidens were supporting you. Through diligent practice of these profound methods, one ultimately transcends mortal limitations to reach the realm of emptiness. Here, the enlightened mind shines full and bright like the moon, with body and mind cooled in perfect clarity.

When all attachments and emotional entanglements are released, the Dao-mind naturally flows freely. Regulate the breath (shenxi) with gentle steadiness, maintaining mental stillness like an unmoving mountain. In this state, one perceives the primordial Dao realm—more wondrous than the legendary paradise of Huaxu. Here, complete freedom reigns, unrestrained like the ancient ecstatic sage Jieyu singing wildly.

At the pinnacle of cultivation, countless scattered thoughts merge into a single radiant spirit. This indescribable state resembles perfectly clear water without impurities—a purified form capable of penetrating mountains. Like wild ducks soaring freely through the sky, the luminous inner elixir (symbolized by the "round brightness") becomes completely unbound. This jade-like inner treasure requires no pursuit of external validation.

The poem concludes with the crucial principle of "host and guest reversal": initial practice treats the original spirit (yuanshen) as guest and primordial Qi (yuanqi) as host; upon accomplishment, their roles invert. By harmonizing Kan and Li (water and fire) and balancing the Five Phases (wuxing), pure Yang Qi coalesces to ultimately refine Yin substances. When spirit fully merges with the Dao, one's true nature manifests beyond triple-world constraints. This ineffable state transcends form yet responds freely to all transformations, completing the work of virtue.

This modern interpretation elucidates the cultivation states described in the Huizhen Ji (Anthology of Meeting the True):

When the Northern Dipper and Southern Star (Daoist astral deities) rotate with radiant brilliance, the practitioner's authentic Qi begins stirring in the depths of the Dantian (energy center) like the "Wooden Youth" (symbolizing pure Yang energy). At the zenith of Yang's ascent, it naturally reverts while Yin descends—this marks the crucial juncture in cultivation. When genuine practice manifests, one's fundamental state becomes pristine as moonlight, penetrating all three realms and ten directions (the entire cosmos), reaching the supreme state of apparent emptiness yet non-emptiness, beyond birth and extinction.

During the "Desire Realm" cultivation phase, the Valley Spirit (Dantian's authentic Qi) begins differentiating, as tranquil emotions merge with the Great Unity (cosmic origin energy). Within the body, clouds and rain rise metaphorically while the eight extraordinary meridians open, allowing one to hear the melodic flow of Qi resembling zither music. When the Primordial Qi emerges from chaos, it circulates through the body's Bagua (Eight Trigrams) and Nine Palaces (acupuncture point matrix), with Kan (Water) and Li (Fire) coupling to fill the entire form. Here, practitioners must calm the mind and regulate breath to harmonize the Dragon and Tiger (Yin-Yang energies), inducing wondrous transformations in the three Dantian that gradually lead to the realm of emptiness.

At advanced stages, worldly desires naturally fade as wisdom manifests. When heart and Shen (spirit) commune, one experiences a trance-like clarity while the Yellow Court (middle Dantian) gathers primordial energy. The energies of the Nine Heavens resonate within, circulating ceaselessly until the spirit can transcend physical form, displaying numinous abilities.

In the higher "Form Realm," the mind becomes mirror-clear as Yin-Yang energies naturally unite within, like winds rising from the ocean floor to nourish internal organs. The Dipper constellations follow Qi's movement while the Heavenly Gate (Baihui point) receives the outbound spirit—all anxieties dissolve as De (virtue/power) reaches perfection. This state seems within reach yet vast as the roc's wingspan.

Upon attaining the wondrous circularity state, dignified bearing and serene meditation arise. The "pot's interior" (body) reveals celestial scenery—clouds and auroras come and go amid the Tiger's roar and Dragon's chant (Qi circulation metaphors). The heart-mind expands as if drinking sweet dew, moving freely amidst "phoenix dances and immortal music" (internal visions). Everywhere glows with auspicious light like crimson snow, while the mind becomes crystalline as winter moonlight, thoroughly penetrating the Dao to transcend worldly pleasures for supreme bliss.

At the ultimate stage, though the physical form remains, transcendence is complete—the sacred spirit purified, all afflictions severed. After breaking through meditation's barriers, the body becomes like a spring-filled vessel, achieving the most perfected state of cultivation.

This passage describes the different realms and common pitfalls in Daoist Neidan (internal alchemy) practice. It begins by depicting the sublime state achieved by advanced practitioners: the Big Dipper encircles them, the Milky Way revolves, while moonlight pierces through clouds to merge with the azure sky. The cultivator attains a body of pure Yang (Chunyang, representing primordial Qi), supported by auspicious clouds and caressed by gentle breezes, experiencing boundless joy—sometimes bursting into resonant songs that echo like rolling thunder.

The text then identifies three misconceptions in cultivation: "Stubborn Emptiness" (Wankong) refers to clinging to sheer nothingness while failing to comprehend the dynamic interplay of Yin-Yang, thereby obscuring one's true nature. "Severed Emptiness" (Duankong) emphasizes the need to investigate the "Three Thefts" (the depletion of Jing, Qi, and Shen by external influences) and the "Four Symbols" (lesser Yin, lesser Yang, greater Yin, and greater Yang) to master the creative transformations of heaven and earth. Only "True Emptiness" (Zhenkong) represents the correct path, requiring the harmonization of Shen (spirit) with breath, the balancing of the Five Essences (corresponding to the viscera), and the pacification of the Six Consciousnesses (sight, hearing, smell, taste, touch, and thought), ultimately culminating in the formation of the Golden Elixir.

The crux of cultivation lies in the dual cultivation of nature and life (Xingming Shuangxiu) and the harmonization of Yin-Yang. Those who obsess over mere emptiness without refining the Golden Elixir will never attain the Great Dao. But practitioners who skillfully regulate the "firing times" (the critical phases of practice), achieve the union of Water and Fire (the interaction between heart and kidneys), and facilitate the fusion of Lead and Mercury (the blending of vital essences) through prolonged cultivation may eventually manifest the Yang Spirit, enabling celestial wanderings. The term "Gourd Heaven" (Hutian) refers to Daoist grotto-heavens and blessed realms, while the "Three Fields" (Santian) denote the upper, middle, and lower Dantian (energy centers).

This scripture describes the profound states and inner experiences of Daoist cultivation. Through harmonizing Yin-Yang and circulating the Zhou Tian (the pathways of Qi circulation within the body), practitioners attain a state where form and spirit (Shen) both reach sublime perfection. The text mentions "golden wells" (referring to the Dantian) producing radiant jade blossoms, symbolizing the successful cultivation of internal alchemy (Neidan).

The practitioner enters a state of ethereal wholeness, where the mind becomes pure and flawless, capable of penetrating heaven and earth. In this state, the "square inch" (the heart-mind) can encompass worlds as vast as river sands, freely enjoying the breeze and moonlight while reclining amidst mist and rosy clouds. Such realms can only be truly comprehended by genuine Dao cultivators.

The second passage further elaborates on the practitioner's state of unified form and spirit, where spiritual awareness flows without obstruction. Transcending the bonds of desire and sensory illusions, the mind becomes empty and luminous, with wisdom penetrating all. This state of purity can induce miraculous transformations, shattering the limitations of time (transcending kalpic cycles) and smashing the fetters of rebirth.

The "Laojun's Chant" section details specific cultivation methods: through breath regulation (collecting "crow's blood" refers to breath control), the six Yang energies circulate within, while the five Qi (energies of the five organs) flow unimpeded. Practitioners experience inner visions of clouds, thunder, wind, and snow within their bodies, while their inner light (Xingguang) shines with penetrating clarity. Ultimately, they complete three thousand meritorious deeds and transcend the cycle of life and death.

The final passage emphasizes maintaining the purity of the spiritual source (one's innate nature), harmonizing Yin-Yang, and entering the state of Chongxu (empty nothingness). The practitioner's mind-mirror becomes perfectly bright, capable of illuminating all illusions, attaining the state of Nirvana (liberation), and manifesting infinite wondrous spiritual powers. The fulfillment of eight hundred virtuous practices demonstrates the perfection of true cultivation.

The Huizhen Ji (Anthology of Gathering Truth) presents the core concepts and states of Daoist cultivation through progressive stages:

The foundation of practice lies in nurturing compassion (considered the essence of the Dao in Daoism), maintaining a peaceful and non-contentious mind, benefiting all beings extensively, and taking humble virtue (De) as the guiding principle. Through cultivation, one may perfect eight hundred kinds of flawless merits (referring to pure and uncontaminated attainments), ultimately transcending worldly dust, walking steadily upon clouds, and ascending from ordinary human state to sagehood.

The scripture describes the rejuvenating state of cultivation: the human body, composed of the four elements (earth, water, fire, wind), inevitably decays. Yet through the wondrous application of cultivation, one may shed the old form like a cicada molting its shell. Aligning with the cosmic interplay of Yin-Yang, the spiritual embryo (original spirit, Yuanshen) separates from primordial chaos, forming a saintly body as light and vigorous as a child's. At the highest attainment, practitioners maintain the profound state of "thusness unmoved" (a Buddhist term denoting the eternal state of true suchness), connecting with the Ultimate Void (the source of Dao), where their Dharma forms (achieved states of practice) become spiritually unimpeded.

Accomplished adepts can command vast primordial Qi (vital energy), manifesting infinite transformations that mirror the primal origin of the cosmos. Riding phoenixes and cranes through celestial palaces, they roam in carefree spontaneity, manifesting transcendent sagehood and becoming immortal exemplars of purity through the ages.

The second passage explains how through "the mystic work of unified Qi" (practices of primordial energy) and "the true refinement of three wonders" (cultivation of the three treasures: essence/Jing, Qi, and spirit/Shen), one may restore the original jade-like countenance (primordial purity) and store cultivation achievements as precious treasures. After nine cycles of golden elixir (Jindan) refinement, the Yang spirit body is perfected—dwelling in true realms with a mind expansive as heaven. Though the external four-element body decays with time's passage, practitioners preserve within an icy clarity (symbolizing pristine nature), achieving divine metamorphosis.

The third section emphasizes precise fire regulation (control during practice): the celestial cycle's firing process (Qi circulation in internal alchemy/Neidan) must balance ascent and descent, with Qi movement accurately traversing meridians. Improper regulation causes ailments like difficulty opening eyes, while prolonged errors lead to demonic states. Practitioners must harmonize the six spirits (senses of eyes, ears, nose, tongue, body, and mind), subdue the three corpses (Taoist malevolent spirits within the body), and conquer the five thieves (desires of sight, sound, smell, taste, and touch), directing fierce flames onto the jade path (proper course). By cycling water and fire within the spirit palace, the elixir is ultimately forged.

The final passages conclude: When Yin-Yang reaches perfection, the Dao's wind becomes pure; through essential refinement, heavenly truth is preserved intact. Discerning hardness and softness, movement and stillness, practitioners cultivate the ninefold returned elixir (highest internal alchemy) to refresh bodily states. At the ultimate stage, one's original nature (Xing) merges with the divine—everywhere revealing the complete body (manifestation of Dharma body), thoroughly comprehending the three emptinesses (self, phenomena, and emptiness itself) without obstruction, uniting with the Supreme Void beyond worldly dust. Their aspiration penetrates heaven and earth; spirit and essence couple (Yin-Yang harmonization); within waxing and waning (cosmic rhythms), true nature is preserved—fully realizing the profound mysteries of creation's primordial chaos (Xuanhuang).

This passage elucidates the essential techniques for cultivating the Way of Pure Yang. "The wondrous refinement of the Nine Yangs" refers to the profound alchemical process through which one's hun and po (the spiritual essences) undergo qualitative transformation, reaching a state of "unrestrained circulation" where they flow freely throughout the being. "The profound meaning coming from the West" subtly alludes to the Buddhist truth transmitted from the West, which shares fundamental principles with Daoist practice—both leading to a state of serene mental expansiveness.

Practitioners must personally realize the "unobstructed Dharma gate"—a universal path to awakening as omnipresent as the sands of the Ganges River—through which the "marvelously perfect" truth becomes manifest. By discarding the dross (distracting thoughts) and preserving the pure essence, one attains the "thusness" of complete enlightenment, allowing one's intrinsic nature to shine in perfect radiance.

Through deep study of the profound principles of "samadhi" (meditative absorption), one becomes effortlessly adaptable to all phenomena, recognizing them as manifestations of the "Primordial Spirit." Special emphasis is placed on harmonizing the "yin soul" (the receptive spiritual aspect) with the "yang spirit" (the active luminous consciousness).

The crucial insight lies in comprehending the "mysterious mechanism" of practice while maintaining crystal-clear mental clarity. Through the process of "cauldron refinement in the elixir field" (a metaphor for Neidan internal alchemy, where the body becomes the crucible for transformation), one ultimately forges the "pure yang dharma form"—an achievement of cultivation where yin elements are completely transmuted. This leads to the complete unification of xing (spiritual nature) and ming (vital life), culminating in the "birthless" realm that transcends the cycle of life and death.

This poem depicts the realm of Daoist cultivators transcending worldly dust and returning to original purity. The first stanza opens with "spring descends from beyond heaven," seeing through the rise and fall of dynasties as fleeting dreams, while time flows unnoticed. The awakened choose seclusion amidst misty mountains and waters, cloaked in raincoats and leaning on staffs in carefree wandering, nurturing their Shen (spirit) and Qi to refine body and mind.

The cultivator's life brims with authentic joy: at home they keep immortal delicacies (snow plums and fire dates), golden waves rippling in jade pitchers, their spirit roaming beyond clouds in drunken ecstasy. Chanting verses to clear winds and bright moon, dancing freely in celestial realms, they comprehend the primordial chaos of Hongmeng, surpassing worldly fetters (the "waves of波罗" representing afflictions).

The second stanza's "returning to origin to cultivate truth" reveals essential techniques: awaiting Yang energy's first stirring (the winter solstice's one Yang birth), harmonizing the Five Phases' Qi. The golden youth (original Shen) enacts righteousness, the jade maiden (original Jing) embodies benevolence—Yin and Yang, firm and gentle perfectly balanced. Within the Huangting (Dantian) immortal lodge, winds of wisdom gather divine assemblies. In jasper vessels wreathed with auspicious smoke, elixirs brew (lead and silver symbolizing alchemical substances), the cultivator's ice-pure flesh and jade bones glowing with rosy light as the Three Marvels (Jing-Qi-Shen) radiate fresh brilliance.

The cultivator's soul becomes light as flying feathers, accompanied by Dao and De (Virtue), proudly roaming the vast void. Their true serene nature remains unchanging as the icy moon illuminating all ten directions. The "Water Melody Prelude" continues depicting cultivation scenes: harmonizing Qi nourishes true life, divine light dispels delusion. Within luminous mountains and waters hides the Mystic Pearl (Neidan), the Northern Dipper's seven stars (Seven Luminaries) as pivot, golden splendor (Golden Elixir) reviving withered wood. Organs settle like stilled wind and smoke, solitary moon atop peaks piercing the Three Realms to nourish the Nine Cauldrons (Dantian).

Intoxicated in the Hua Xu paradise (ideal immortal realm), jade youths support them, riding herb-carriages (píng) through the skies. The pure Yang sacred realm transcends cosmic limits, primal nature manifesting in stillness, appearing and vanishing at will. The sword of wisdom severs demonic obstructions, breaking samsaric cycles. Guarding inner breath, sweet dew (true Qi) moistens the spirit terrace. Four Symbols and Five Phases return to the Three-in-One (Dao), cauldron smoke condensing like bellows (tuóyuè) stirring clouds and thunder (celestial cycle). Golden flowers bloom in water (kidney's true Qi), jade lotuses blossom in fire (heart's original Shen).

Cultivation follows heaven-earth's numbers (nine-six as Yin-Yang extremes, three as heaven-earth-human), forging robust Dao-bodies to companion clear winds and bright moon eternally. In profound mystery, Jing transforms to Qi, Qi to Shen, finally merging with the formless Xi Yi (Dao's original state). The Dao's transformative power is boundless as returning to ultimate joy, playing leisurely in Penglai nearby. Through alchemical imagery, the entire poem expresses liberation from sorrow and realization of Dao's truth.

The Huizhen Ji (Collected Writings on Meeting the True) scripture passage primarily discusses how Daoist practitioners can transcend worldly attachments to pursue longevity and liberation.

The first section, Manjiang Hong Man (Slow Song of the Full River Red), explains that cultivators must see through the illusions of wealth and status, wielding the sword of wisdom to sever worldly ties and break free from the cycle of life and death. Practitioners should abandon cleverness and cunning, focusing instead on quiet contemplation in serene surroundings, finding companionship in green waters and blue mountains, with the clear breeze and bright moon as intimate friends, content in their solitary joy. Maintaining a tranquil heart and joyful spirit, they roam freely like lone clouds and wild cranes. Diligently cultivating the Dharma, they purify all obstacles to attain the wisdom of Bodhi.

The second section emphasizes the need for unwavering determination in spiritual practice, breaking through worldly constraints. Keeping the heart-mind harmonious and unimpeded, they refine their innate purity. The internal Qi (vital energy) circulates, penetrating the Nine Palaces (a Daoist term referring to key energy centers in the body) and transforming the Three Lights (sun, moon, and stars). The mind becomes radiant and luminous, utterly clear and untainted. One reaches the true state of neither within nor without—neither arising nor ceasing—transcending the cycle of rebirth.

The segment Zhu Ying Yao Hong (Flickering Red Shadows), dedicated to Gao Yingchan, describes the methods of cultivation: the heart must remain calm, following the master’s guidance. Mastering the secret methods of Heaven, one purifies the internal Qi until it becomes as clear as ice and snow. Balancing Yin-Yang, practicing at the proper hours, and absorbing the Three Lights through breath regulation, one engages in the dual cultivation of nature and life (Xingming Shuangxiu, a core Daoist practice integrating spiritual and physical refinement), harmonizing Heaven and Earth. Devotion is essential—neither treating the path lightly nor clinging to external distractions. Upon achieving success, one ascends to the immortal realms.

Finally, Jing Shan E (Admonition on Good and Evil) points out that the gate of the Great Dao (the Way) is now open, coinciding with the celestial cycle of the Jiazi era (a significant temporal concept in Daoism). Among the ranks of the immortals in the Sanqing (Three Pure Ones) celestial realms, one surpasses past and present. The passage as a whole underscores the necessity of transcending worldly concerns, focusing on inner cultivation, and ultimately attaining the state of eternal transcendence.

This scripture describes the process of Daoist practitioners transcending worldly concerns to cultivate the inner elixir (Neidan), using poetic language to depict the stages of spiritual refinement.

The first passage explains how adepts must transcend the darkness of mundane existence, abandoning wealth and honor to break through the constraints of illusion like chiseling open the realm of perfect enlightenment. Ordinary people drown in the sea of desire, lost in the cycles of rebirth, helplessly trapped in the underworld (Fengdu). Only by attaining the true state of cultivation can one ride the clear wind to liberation, though such opportunities are exceedingly rare.

The "embroidered needle" metaphor in the second passage illustrates the focused concentration required in cultivation. Practitioners see through the illusions of fame, profit, and material concerns—only with purified mind can they comprehend the mysteries of heaven and earth. Through refining the "three thefts" (Jing, Qi, and Shen), they circulate the celestial bodies, cooking the primordial energies (Xuanhuang) in the alchemical furnace (Dantian) to crystallize the essence of heaven and earth. In the state of profound stillness, the body merges with the mysterious state of Xiyi (the subtle Dao), a wondrous realm incomprehensible to ordinary people.

The third passage details the cultivation of the inner elixir (Golden Elixir) by nourishing the three Dantian energy centers and cleansing worldly defilements. Like Mencius who found joy in poverty while upholding the Dao, practitioners maintain minds clear as lakes. By refining the essences of sun and moon (toad essence and crow marrow), they fill their chambers with jade frost (Neidan radiance), forging a mystical yang-spirit capable of soaring beyond the nine heavens.

The final "Water Dragon Chant" sections depict the energetic transformations during cultivation: the yin and yang energies (Chonghe) move in celestial rhythm as wind, thunder, and lightning condense into spiritual rain nourishing body and mind. When the winding river (Dantian) becomes crystalline, the crow (solar essence) captures the jade rabbit (lunar essence), while the cassia tree (inner landscape) exhales crimson mist. The swirling dual energies coalesce into golden light, forging a youthful countenance and robust health, ultimately revealing the pure true form. The last passage describes how heaven (Qian) and earth (Kun) divide yin and yang, with misty energies transforming into vessels—through the cultivation process of the mother (Kun) nurturing the child (Qian), the spirit chamber becomes purified, manifesting wondrous visions of clear breezes, bright moons, and the golden child (yang-spirit) dancing in flight.

This passage describes the mystical experiences encountered during Daoist Neidan (internal alchemy) cultivation. Through Neidan practices, the practitioner attains transcendent states and perceives wondrous transformations of Jing (essence), Qi (vital energy), and Shen (spirit) within the body.

The first paragraph depicts the practitioner entering deep meditative absorption, as if returning intoxicated from the legendary paradise of Huaxu. The body's vital gateways (jade passes) naturally close and reopen. Here, the practitioner experiences a state of pure clarity and boundlessness, merging with the void, free from all constraints.

The second passage illustrates specific visions of Neidan practice: wisdom illuminates the heart-mind as the three treasures (Jing, Qi, and Shen) gather in the Dantian (energy center). Like flames in a cauldron igniting alchemical blossoms, a fragrant energy rises from the "sea bottom" (lower Dantian). The practitioner feels light as a marionette yet moves with effortless flight, their radiant aura intermingling with celestial hues.

The third section portrays the profound cooling stage of cultivation: the chest expands like frost-covered plains as internal heat dissolves and clouds disperse, achieving the supreme harmony of Yin-Yang. Returning to the primordial state of innate purity, one attains the fruition of Bodhi (awakening).

The fourth passage explains how perfected beings master cultivation's essence—regulating breath and nurturing nature to harmonize the five organ energies (representing Yin-Yang dynamics). Maintaining centered equilibrium, they ultimately reach the ageless realm of Eternal Spring, roaming freely through the pure Dharma realm.

The Ruì Hè Xiān verses emphasize the Daoist's detachment from worldly fame and wealth. By refining the "valley spirit" (Dantian Qi), the true energy circulates like a bellows' natural rhythm. Within the jade furnace and golden cauldron (metaphors for the body), the elixir is forged—purifying spirit to realize the truth of luminous emptiness.

The Yǒng Yù Lè section correlates celestial movements with Neidan: the body rotates like heavenly orbs (the Seven Stars of the Dipper). Refining "turtle essence and toad marrow" (vital substances) and "phoenix dew with crow blood" (essential fluids), the mystic pearl (inner elixir) coalesces in the cauldron. When the Golden Elixir crystallizes, its radiance erupts like nine dragons soaring through the skies.

First Stanza:

A flash of lightning pierces the golden hall (the Dantian), as the Maiden of Spirit (Shen, the divine consciousness) returns to the silver palace (the upper Dantian). Celestial music resounds, and a pure banquet is held amid a joyous crowd. Emerald curtains hang low, pearl blinds are gently rolled up, and auspicious energy glows like radiant clouds. The vast, frosty sky stretches endlessly, where the clear breeze and bright moon illuminate the practitioner’s true original face. This realm of perfect emptiness knows no obstruction—its divine power pervades all, boundless as the Taixu (the primal void).

Second Stanza:

Seeing through the petty pursuits of fame and profit—tiny as a snail’s horn or a fly’s head—one decisively severs these worldly entanglements. Raising the sword of wisdom in an instant, it points directly to the vital pass of cultivation, revealing the profound truth of the Dao (the Xuan Yuan, the primordial origin). Delusion scatters like clouds; the meditative mind shines like ice, suddenly manifesting the awakening of moonlight and breeze. A thousand streams of clear water reveal their depths; a single moon illuminates all directions. Standing alone between heaven and earth, one embodies the flawless, unimpeded zhenru (true suchness). Far and near merge into one; coming and going are distinct yet undisturbed. Severing the dualistic attachments, auspicious signs manifest as the yang spirit emerges. Reaching the cool shore of liberation, one awakens to the lively essence of practice. Whether sitting or reclining, it is as if surrounded by jade trees and celestial blossoms—majestically attaining the wulou (flawless) sage-fruit, perfectly penetrating the profound mysteries of all awakened ones.

Third Stanza:

The sword of wisdom is razor-sharp, scattering a hundred demonic obstructions. Subduing wild thoughts fierce as tigers and dragons, one wields divine transformations. Thunder roars like iron drums; golden serpents dart like lightning as chaotic clouds surge forth. Rivers and seas churn with towering waves—two mighty beasts locked in mortal combat. The true fire of the Three Mountains (the three Dantian) erupts; the nine heavens blaze with radiant clouds, enveloping the luminous inner landscape like precious jewels. Amid a thousand auspicious rays, a fleck of golden light (the Golden Elixir) appears, refined repeatedly in the crucible (the alchemical cauldron). Forged into jade nectar and crystalline blossoms, the skin becomes snow-pure, revealing the true form of the Jade Person (the yang spirit). The Wooden Youth (the liver spirit) joyously greets it, filling the courtyard with rare fragrance upon its return.

Fourth Stanza:

The Primordial Qi (Xiantian Yiqi) swirls and revolves, turning the cosmos and manifesting infinite divine transformations. Creation ascends and descends; east and west invert as Metal (the lungs) and Wood (the liver) unite in harmony. A thousand crimson clouds intertwine with golden radiance—surely the sun has returned to the moon’s palace (Yin-Yang in perfect balance). Exotic fragrances vie with the glow of cinnamon blossoms; Six Yin and Nine Yang (the harmony of Yin-Yang) resonate together. Only when clouds disperse and mists clear, when winds are fresh and the moon bright, does the original face appear. In stillness, serenity deepens; in leisure, contemplation grows profound—freely roaming the Dharma Realm. The celestial net, sparse as the Milky Way, and the iron-like Mysterious Pass (the crucial juncture of practice) suddenly swing open. Hidden and manifest, shifting and unfathomable—within emptiness lies wondrous existence, merging with countless sublime states as vast as the Ganges’ sands, uniquely mastering the boundless work of the Dao.

Final Passage:

Divine light blazes brilliantly; sorrow and joy, delusion and thought, all cease. In the wilds of no-man’s land (the realm of purity), majestic and refined energies merge into one. Like wind and thunder nourishing all things, it unfolds the wondrous function of heaven and earth in harmony. Transforming into sweet dew to nurture the seeds of wisdom, lotuses bloom to reveal auspicious signs. Facing the brocade canopy of the Yellow Court (the middle Dantian), the sacred embryo (the Inner Elixir) is wondrously conceived.

This passage depicts the realms and phenomena of Daoist Neidan (internal alchemy) cultivation. The first paragraph describes the state of accomplished practice: the body enveloped in auspicious light, as if bathed by nine dragons spouting water, ascending to the jade platform of immortal realms, roaming freely in the state of eternal life. Amid golden goblets of fine wine and celestial music, dancing upon radiant jade flowers carried by the wind, one experiences true joy and sees through the cycle of worldly life and death.

The second paragraph illustrates the internal Qi circulation during cultivation: using spiritual power to rotate the celestial wheel (referring to the microcosmic orbit), comprehending the true Dao in stillness. The three lights (sun, moon, stars) circulate within the body, the five Qi (energies of the five organs) harmonize, while the Northern Dipper and Southern Star (acupoints) revolve like a flowing Milky Way. When the jade gate (Dantian) opens, the three chariots (Jing, Qi, Shen) advance together like golden oxen. Suddenly, thunderous vibrations arise within, red light illuminates everywhere, ultimately coalescing into the priceless Golden Elixir (round pearl), securely stored by the Wooden Child (original spirit), ultimately realizing the great Dao of emptiness.

The six "Southern Songs" are all cultivation mantras:

The first describes stillness practice: the heart settles like a caged monkey, the mind reins in like a wild horse no longer galloping. Concentrating spirit and gathering Qi to merge with emptiness, transcending temporal constraints. Beneath the bright moon and clear breeze, enveloped in auspicious light over sacred lotuses, the practitioner (symbolized by the wooden man and stone woman representing quiescent body-mind) jointly contemplates the mysteries, ultimately achieving golden immortality.

The second focuses on foundational cultivation: stabilizing the root of life (solid stem), mastering the pivot of creation. Eliminating distractions (plucking flowers and leaves), harmonizing Yin-Yang energies to penetrate the three Dantian. Using the riverbanks (Governor and Conception vessels) to balance Yin-Yang (crow and hare), refining lead and mercury (essence and energy) in the alchemical furnace until nine cycles complete and golden light permeates the body.

The third details self-refinement: severing distractions, purifying mental currents. Internal breath flows continuously like bellows (tuoyue), Qi circulating through the three palaces (upper, middle, lower Dantian) in accord with celestial cycles. Using gentle fire to warm the golden cauldron (lower Dantian), following firing rules until yang light subtly appears in the perfected pure yang body.

The fourth describes nature attainment: the mind shines like candlelight, original nature clear as the bright moon. Within the body, transparent as an ice jar yet containing thunder's might, interconnected with all celestial phenomena. Upon realizing the great Dao of Wuwei (non-action) and aligning with heavenly mechanisms, spiritual powers manifest freely, pacing the void to return to the dharma realm.

The fifth explains meridian cultivation: purified organs generate primordial Qi (the people's mountain denoting Dantian). Iron oxen (true Qi) plow the three fields day and night, wind and thunder surge through golden wells (channels). Mastering firing regulation, when the ice-flesh jade-bones (pure yang body) gradually form, the square-inch heart (Dantian) radiates complete illumination. After ingesting the Golden Elixir, one roams freely in celestial flight.

This scripture elucidates the profound states and cultivation methods of Daoist practice, employing poetic language to depict the vision of attaining perfection through spiritual refinement.

The first section describes how practitioners transcend worldly riches and honors by cultivating the primordial yang qi (the body's innate vital energy). After completing the eighty-one celestial revolutions of practice, they ascend effortlessly to the immortal palaces of Penglai. The "fire dragon and water tiger" symbolize the yin and yang energies within the body, while the "pivotal mechanism of the seven regulators" refers to the circulation through vital acupoints.

The second passage portrays the wondrous experiences during cultivation: the internal qi flows as cool and clear as autumn light, while the chest harbors magnificent vistas, allowing transformations as agile as a dragon. The practitioner rides a tiger and commands birds under the moonlight (symbolizing mastery over yin and yang), perfecting the alchemical work to attain a state of divine freedom.

The "Plum Blossoms by the River" section uses metaphorical imagery to depict the refinement of the Mysterious Pearl (the inner elixir): flashes of lightning and the Yellow River flowing backward symbolize the majestic momentum of qi circulation. "Six yin lines returning" refers to the cyclical interplay of yin and yang, while the "sevenfold reversion" denotes the seven stages of inner alchemy, culminating in union with the Dao.

The fourth passage emphasizes the arduous nature of true cultivation, requiring severance of worldly attachments and grievances to wander freely like clouds and water. "Kan and Li" represent the water and fire trigrams from the Bagua, symbolizing the harmonization of yin and yang. "Winding River" metaphorically describes the pathways of qi circulation—once the inner elixir is perfected, one can bring peace to the world and aid the people.

The fifth section employs autumnal imagery to illustrate the cultivated state, where all things return to their roots, symbolizing the return to primordial simplicity. "Yellow Robe" derives from the Yijing, embodying the beauty of harmony, while the "Golden Elder" signifies a realized adept, whose gatherings with immortal youths reveal a carefree and liberated nature.

The final passage describes the genuine state of cultivation where ignorance and afflictions are severed, with moonlight illuminating all—a metaphor for luminous wisdom. "Eyebrows trimmed in perfect alignment" is a physical marker of accomplished Daoist adepts, signifying the attainment of the supreme state of purity and wuwei (non-action).

The Huizhen Ji collection of poems describes the realms and experiences of Daoist Neidan (internal alchemy) practice.

The first poem Caisangzi portrays an adept achieving the state where nature and life merge into one, with the spirit roaming freely. The True Void (the purest primordial state in Daoism) expands like heaven and earth, while primordial Qi floats in the Great Emptiness. Through the cultivation of meditative stillness and wisdom, the practitioner realizes their true nature, uniting with the cosmos while maintaining a body of pure Yang.

The second poem depicts the Light of Nature (the innate spiritual radiance) shining like the bright moon upon the Three Realms. During practice, the interaction of Shen (spirit) and Qi produces "jade frost" (a Neidan term for condensed vital essence). When the "golden flowers" (symbolizing alchemical attainment) bloom, their pure fragrance fills the air, manifesting the transmission of the Great Dao.

The third poem explains how the Light of Wisdom dispels distracting thoughts, purifying both form and spirit. The adept masters the "divine mechanism" (profound principles), and though the ultimate reality transcends verbal expression, its radiance illuminates all directions.

The fourth poem emphasizes persistent cultivation to comprehend the transformations of Yin-Yang. Through breath regulation (the "bellows" metaphor for breathing) harmonized with cosmic rhythms, one refines the body to pure Yang, ultimately mastering the creative transformations of the universe.

The two Lü Tou Ya poems provide more detailed descriptions of Neidan processes:

The first stanza describes the movement of true Qi like celestial steeds, following seasonal energy shifts. When "water and fire interact harmoniously" (Yin-Yang balance), the six Yin aspects disperse while three Yang aspects gather, revealing the golden elixir's radiant light. The practitioner experiences sudden awakening to their true nature, attaining spiritual freedom.

The second stanza takes "Xiyi" (emptiness and stillness) as foundation for Qi circulation through the cosmic orbit. Using symbolic terms like "clay ox and wooden horse" (representing alchemical methods), the poem describes the "seven returns and nine restorations" (complete alchemical cycles) that ultimately forge the sacred embryo. The entire work abounds with vivid Neidan imagery and descriptions of spiritual states.

This passage describes the state attained by Daoist practitioners through cultivation, where they transcend worldly existence. Through prajñā (wisdom) practice without delusion, practitioners enter samādhi (meditative absorption) and ultimately realize Wuwei (the state of natural non-action), surpassing mundane reality to reach authentic realms. During cultivation, their bodies radiate crimson and pristine lights, with internal and external energies harmoniously aligned.

The celestial grotto (immortal realm) where cultivators dwell is crystalline and translucent, their yang souls light and swift as the wind, with divine radiance shining boundlessly across eternity. At this stage, body and mind become purified, merging with the void, while the vast righteous Qi remains complete and undiminished. Upon achieving spiritual fruition, they manifest sage-like transformations, penetrating heaven and earth like luminous pearls revealed—utterly unobstructed, with every place becoming the Jasper Pool of immortality.

The second part details the inner experiences during cultivation. When all karmic conditions (distracting thoughts) cease, the spirit becomes serene and harmonious, with old ailments dissolving into the state of pure emptiness. Within the body, the "Seven Luminaries" (sun, moon and five planets) welcome the True Qi (primordial energy), the "empty chamber" (Dantian) becomes pure as ice, guarding the Nine Heavens. Before the "Twelve-Storied Tower" (referring to the twelve meridians), the "Five Qi" (energies of the five organs) soar skyward, while the Golden Portal (upper Dantian) suspends the Sword of Wisdom, where the "Immortal Child" (a Neidan term for the original spirit) manifests its cold radiance—its edge sharp enough to lift the sun and moon.

Practitioners concentrate their essence within the "gourd crucible" (Dantian), stimulating the "Mystic Frost" (a Neidan term for primordial Qi) to generate the supreme marvel (Golden Elixir). Ultimately returning to the "dimly discernible" (undifferentiated chaos), the Ocean of Nature becomes immersed in non-action, transcending the "Three Emptinesses" (emptiness of self, phenomena, and emptiness itself). This section further describes how "Qian's Origin" (heavenly virtue's beginning) merges with "Kun's Softness" (earthly virtue's pliancy), as Yin and Yang harmonize to produce "Heavenly Waters" (primordial essence), setting creation in motion. Through the "Three Essentials" (Jing, Qi, Shen) and mutual generation of the Five Phases, the "Divine Water" (original essence) and "Nine Qi" ascend while the "Six Yins" subside quietly, generating purple mist (a Neidan vision), before finally returning to the source. Within the "Jade Grotto" (Dantian), the Three Flowers (of Jing, Qi, and Shen) blossom with golden pistils, attaining resonance with the Void Sovereign (the source of Dao).

In the fifth volume of the Collected Works on Realizing Truth, Chao Ranzi Wang Jichang writes:

Human nature is originally pure and untainted, without distinctions of birth or death. Yet as it flows with external phenomena, it is shaped by the transformative forces of Yin-Yang. The human body cycles through the five turbidities (kalpa-turbidity, view-turbidity, affliction-turbidity, beings-turbidity, and lifespan-turbidity) in this degenerate world, repeatedly tormented by the eight sufferings of birth, aging, sickness, and death. In this endless cycle of birth and death, when can one attain liberation? I urge you to awaken and resolve to grasp the profound mysteries of heaven and earth.

The seven luminaries (sun, moon, and five planets) penetrate the three wonders (heaven, earth, and humanity), revolving the celestial mechanism. Following the flow of Qi, through the practice of the "nine returns and seven reversions" (a Neidan term referring to the circulation of essence and vital energy), one refines the elixir in accordance with the proper timing. Within the golden cavern (Dantian), jade blossoms bloom, while the five Qi (of the organs) swirl like crimson snow.

Cultivate the vast righteous Qi in stillness, reversing the creative transformations of the Five Phases. The spiritual wind circulates up and down within the body, connecting with the three isles (upper, middle, and lower Dantian). Aligning one's practice with the celestial cycles, embrace the pure and singular Qi. The physical form requires nourishment from the formless Dao, and the unfeeling transformations give birth to the treasures of sentience. Maintain bodily health and eternal spirit, dwelling alone in the Zen heavens with a mind bright as the full moon.

Restrain the restless mind and enter deep tranquility. The mysterious mechanism operates between the southern fire position and the northern water palace. Open the mercury cauldron (alchemical furnace), where the tiger's roar and dragon's chant nurture the nine Yang Qi, dispelling Yin impurities. Savor fine wine and play the wind zither, sending the wood child (the liver spirit) to drink freely. The six viscera are at ease, the five spirits rejoice—transcending the mundane to enter the sacred realm, where the purified body commands reverence from ghosts and deities.

Nourish the innate true nature, cultivate the original spirit (Shen), and harmonize the two Qi of Yin and Yang. Follow the celestial movements and regulate the "extraction and replenishment" (fire control in alchemy) according to the proper hours, especially on the Geng-Shen day (a key date for Daoist practice). Refine the mercury blossom and lead silver (inner alchemical substances)—eight kinds of jade nectar pure as new snow, with skin glowing like rosy clouds. Fragrant winds sweep the land, and the western guest (metal Qi) embodies pure intent. Like the dreamland of Huaxu, the spirit roams spring scenes beyond the material world, revealing the true self.

Knock at the mysterious gate (a key point in cultivation) and wander the cloud-capped mountains. Flower light glows on moist stones, pine breezes soften, and zither melodies dissolve worries while fine wine opens the heart. The mind transcends in leisure—all realms vanish, leaving only the self. The nine Yang return, the six Yin recede, and the eight treasures (inner essences) are gathered, their golden light perfected. The entire body radiates like rosy clouds, form and spirit merging seamlessly with the Great Void, welcoming immortal guests beyond the dust of the world.

Sever worldly ties, and the wind of wisdom arises. With the celestial pivot and earthly axis as the hinge, turn the mysterious mechanism—the Dipper's handle moves like the essence of the toad and rabbit (sun and moon). The kidney palace (water element) gathers vital essence for refinement in the jade furnace. Essence manifests, ten thousand spirits are clarified, and the three platforms and six ministers (celestial officials) celebrate in the heavenly palace. Drink the jade nectar to nurture true essence, returning to the sea of awareness in perfect fusion. Observe the state of perfect freedom—its majesty towering beyond all.

This passage depicts the transcendent spiritual state and essential cultivation methods of a Daoist practitioner. The adept dwells in a thatched cottage enveloped by emerald mountain mists, quietly playing chess beneath pine-framed windows and leisurely strumming the zither in song, finding profound joy in simple poverty—a state of mind surpassing that of nobles and princes. Untroubled by worldly favor or disgrace, he nurtures subtle Qi (vital energy) within the Lingtai (the seat of consciousness), achieving more than through forced meditation. When the mind becomes as clear as the bright moon, one comprehends samadhi (meditative absorption) and the six supernatural powers, ultimately attaining the supreme and perfect fruit of Dao.

The "Drunk in Penglai" section reveals the cosmic origin: from the primordial Hunyuan Qi (Chaotic Origin Energy) emerged Heaven and Earth, a mysterious creation enduring since antiquity. The cultivator must understand the cyclical principles of Yin-Yang, harmonizing Metal and Wood, Kan and Li (alchemical terms representing different energy attributes), and forging the Danji (foundation of internal alchemy) amid storms and perils. Through nine revolutions and three returns of refinement, when the Yin and Yang lines complete their numbers, the Valley Spirit (Qi of the Dantian) transcends physical constraints, ascending directly to Kunlun (the sacred Daoist mountain) to roam freely with the clear wind and white clouds.

"Libation to the River Moon" portrays cosmic operation: when primordial chaos first parted, the Big Dipper regulated celestial phenomena; the sun and moon moved along their orbits, the four seasons cycled, and Yin-Yang harmonized—all manifestations of supreme creative power. As divine work divided Heaven and Earth, the Dragon and Tiger (Yin and Yang energies) spiraled within the Dantian. The practitioner must nourish the Divine Embryo (original spirit) until the Mysterious Pearl (internal elixir) manifests, illuminating boundless Dharma realms.

The second passage explains Neidan (internal alchemy) cultivation: the square-inch true heart contains Taiji (Supreme Ultimate), cultivated where the Mysterious and Yellow (Heaven and Earth) intersect. One must align with the solar and lunar rhythms, refining Dragon and Tiger (Water and Fire) within the alchemical cauldron. When civil and martial fires are perfectly balanced, golden stamen-like elixir forms, achieving a state pure as ice and flawless as jade. In this harmonious equilibrium, the practitioner silently unites with the Heavenly Root (cosmic origin), shining like a luminous pearl upon the constellations, transcending worldly dust across eons to reach an ineffable state of radiant clarity.

"Song of the Southern Country" describes cultivation methods: drifting like duckweed according to circumstance, shedding worldly burdens, a simple life using stones as pillows and stream water for rinsing nourishes vast righteous Qi. Master the coupling of Turtle and Snake (Water and Fire), refining golden pearls (Golden Elixir) from Black Water (kidney Qi). When the pill-sized elixir is complete, one freely wanders within the Sun-Moon Pot (the inner cosmos).

This cultivation formula elucidates the essential principles of Daoist Neidan (internal alchemy) practice. During cultivation, one must regulate the rhythm of advancing and withdrawing the fire phases (huohou) like harmonizing the movements of the sun (represented by the crow) and moon (represented by the hare). The essence (Jing), vital energy (Qi), and spirit (Shen) are refined within the Dantian (energy center), envisioned as the cosmic crucible of creation (Qian-Kun furnace). Skillful adjustment of practice intensity coupled with a joyful mental state allows the perfected Golden Elixir (Jindan) to bestow perpetual vitality upon the physical form.

Mental cultivation should reach a state of pristine purity—the heart-mind becomes as clear as a translucent jade vessel. When encountering external phenomena, maintain transcendent detachment, remaining unbound by any worldly attachments. Though the physical appearance may resemble ordinary people, within resides an eternal radiance akin to luminous night pearls.

The third passage emphasizes precise fire-phase regulation during the celestial cycle (Zhou Tian) practice. Through prolonged cultivation (symbolized by the metaphor of "nurturing an iron ox"), when the practice reaches completion, one achieves the transformation of "changing bones and returning to yang" (a metaphor for physical transcendence). Upon attaining prajñā wisdom (the "other shore" of enlightenment), one transcends the cycle of rebirth, peacefully steering the boat of primordial spirit (Yuanshen) back to the source (ultimate bliss), washing away worldly ties until the mind becomes as pure as a lotus blossom.

The fourth passage describes meditative absorption (Ding). While outwardly appearing dull, internally the true Qi circulates within the Dantian (the sun-moon furnace). By harmonizing yin-yang (Xuanpin, the mysterious feminine-masculine) to balance the three vital substances (Jing-Qi-Shen), one reaches a blissful state resembling mild inebriation. This state remains undisturbed by external phenomena, as naturally ordered as the rotation of the Northern Dipper. Within these mysterious transformations, one comprehends the Dao—body and mind suffused with crimson light, merging with the Supreme Void (cosmic origin).

The fifth passage reveals the Dao resides within the three Dantian of the human body. Recognize all phenomena as fundamentally unified, avoiding partial attachments. When cosmic principles permeate the "inch-square heart" (mind), one apprehends the profound mysteries of the Dao. The Dao resembles an entity that grows more indestructible the deeper one drills, more exalted the higher one gazes—transcending sensory perception yet surpassing temporal boundaries, perfectly integrating substance and function.

The concluding section emphasizes sudden awakening to the nature of life and death, subduing the "mind-monkey and thought-horse" (discursive thoughts). Only by relinquishing all attachments can one receive the true transmission of heaven and earth. Through purifying body-mind and harmonizing yin-yang, one absorbs celestial-terrestrial essences to nourish the spirit. At the pinnacle where spirit and Qi interpenetrate and subject-object distinctions dissolve, all sounds transform into celestial harmonies, yang energy crystallizes into immortal realms, and body-mind becomes pure as jade-ice. The spirit soars freely beyond material constraints, ultimately uniting with the central earth phase (symbolizing the middle Dantian) to "steal the creative mechanisms of heaven and earth," thereby completing the Golden Elixir cultivation.

This passage describes the realms and experiences of Daoist cultivation. Through purifying the heart-mind (Shen) and harmonizing Yin-Yang, practitioners transcend worldly existence to attain sublime states.

The first section explains how adepts achieve lightness and freedom by clarifying their spiritual vision (mysterious perception with purified Shen). When wisdom's radiance shines forth after dispelling delusions, the heart becomes pure as ice, ultimately enabling ascension to the immortal realms (Jade Pool). In these celestial domains, they joyfully commune with immortals amid fragrant mists and ethereal music, roaming in carefree liberation beyond the cycles of life and death, finally merging with the Dao in supreme unity (the undifferentiated state of Xi and Yi).

The second section elucidates profound cultivation principles. When the heart-mind attains stillness, union with heaven and earth occurs. Harmonizing the Five Qi (energies of the Five Phases) preserves one's primordial true nature. During alchemical refinement in the golden cauldron, the "medicinal substances" boil vigorously. Successful completion forges an unimpeded Dharma-body, awakening one's fundamental nature and transcending samsara.

The third section depicts meditative stillness. Through prolonged mental purification (clarifying the Shen), one enters Wuwei (non-action) like an infant's natural innocence. No deliberate distinction between truth and illusion is needed—simply remaining untainted by worldly dust allows one's intrinsic nature to shine with the purity of a luminous pearl.

The fourth section details Neidan (internal alchemy) practice. Like a hidden dragon accumulating vitality (firm and strong), energy circulates through the three passes and nine curves within the body. Refining the Golden Elixir in the jade cauldron eventually fills the bodily vessel with radiant energy, illuminating the entire form to achieve the authentic state of heaven-human unity.

The three "Spring in Wuling" poems further expound Neidan techniques:

The first poem discusses harmonizing the Yin-Yang energies of water-fire and metal-wood (north-south and west-east positions), forming the elixir in the Dantian (Palace of Imperial Flourishing). Success enables spiritual journeys to the three immortal islands.

The second poem describes gathering medicinal ingredients (the two-eight medicinal sprouts and snow-gold essence), using Wuwei methods in the four-legged cauldron to coalesce the three treasures of Jing, Qi, and Shen (the crystalline gathering of three natures).

The third poem explains refining with gentle fire at the ocean-floor Dantian, forging the pure Yang body (jade-like muscles glowing with white splendor) to accomplish the sage's perfected form.

The path of cultivation remains unchanged through the ages—it is only human hearts that lose their way. Many lament that the Dao of heaven seems distant and unattainable, yet the ladder to the celestial realms stands merely three inches away (a metaphor for the accessible threshold of practice). Regrettably, nine out of ten fail to reach it, as vast as the gap between clouds and mud. But with sincere understanding of its mysteries, accumulated merit (De) can rise to heaven's heights.

Life drifts like a boat on the boundless sea of suffering, with sentient beings swirling like schools of fish. Most drown contentedly in the currents, while a rare few transform like the Kun fish becoming a Peng bird (from the Zhuangzi)—spreading wings to soar beyond the nine heavens, transcending worldly fetters.

Observe the sun and moon cycling through seasons: dynasties rise and fall like the Tang palaces and Han towers, Chu gardens and Qin pavilions, all adrift in the ocean of desire. Only the awakened pierce through worldly attachments to reflect on their original nature. Understanding the truth that "three begets all things" (Dao gives birth to One, One to Two, Two to Three), they harmonize Yin-Yang (Kan and Li) to condense the Mysterious Pearl (a Neidan term) within violet radiance. Forging a body of pure Yang as translucent as mica, they finally shed their mortal shell like a cicada, freely traversing the Three Realms (Desire, Form, and Formless).

Cold winters and hot summers hasten aging—no chests of gold can halt impermanence. Having seen through samsara's truth, one must nurture primordial Qi (Yuan Yang), using the body as a crucible to refine heaven and earth, escaping the net of life and death. The enlightened mind becomes cool and lucid, piercing past, present, and future.

This spark of spiritual light (Ling Guang) wanders through the six realms of rebirth, changing forms while drowning in suffering's sea. Recognize the physical body as a temporary coalescence of the Four Elements (earth, water, fire, wind), and see through glory and decay as fleeting as lightning. Awaken like Zhuang Zhou dreaming of a butterfly, single-mindedly cultivating to break through the Mysterious Pass (a vital Dantian point). Through relentless refinement, return to original purity—only then can one comprehend heaven and earth, wielding spiritual powers as freely as the autumn breeze.

Study heaven and earth's cyclical patterns, sensing the wondrous transformations of the Five Phases (Metal, Wood, Water, Fire). Move with the natural ease of orioles weaving through willow branches, merging with the spiritual energy of the Three Sacred Mountains (Penglai, Fangzhang, Yingzhou) and Four Seas.

This passage describes the realms and methods of Daoist cultivation. The general meaning is as follows:

Through the practice of Neidan (internal alchemy, a Daoist method of achieving longevity by regulating Jing (essence), Qi (vital energy), and Shen (spirit)), the practitioner harmonizes Yin-Yang like clouds gathering around the six lines of the hexagrams (symbolizing cosmic transformations in the Book of Changes), progressing step by step as with the "fire phases" (a Neidan term referring to the gradual refinement process). The "sevenfold return" (a cyclical process of Qi circulation) must be diligently cultivated—the resulting Golden Elixir will be as fragrant as orchids, commanding reverence even from spirits, and capable of expelling the "Three Corpses" (malevolent spirits believed to reside in the human body according to Daoist belief).

The cultivator must shatter worldly desires, extinguish the flames of ignorance (a Buddhist term referring to delusion and afflictions), and transform them into the light of wisdom. When the mind awakens, one may ascend to the Shangqing (Upper Clarity) celestial realm (one of the highest Daoist heavens) and be inscribed among the ranks of immortals. The true nature manifests like the radiance of the "Nine Yang" (symbolizing pure Yang energy), transcending the mundane world.

Cultivation requires the leisurely detachment of drifting clouds and flowing water, the steadfast integrity of pines and bamboo, the pursuit of the true Dao, and the sweeping away of delusions. One's will must be as unyielding as iron, content with simple sustenance (a humble diet), and maintain the open-hearted humility of the "Valley of Folly." Through meditative practice, spiritual clarity emerges, luminous as moonlight illuminating past and present. One attains the state of "Primordial Unity" (the original source of the Dao), connecting all directions, where the true nature knows no distinction.

The subsequent lyrics to the tune of "Calming Wind and Waves" and "Groping for Fish" further elaborate on the realms of cultivation: practice illuminates the mind, freeing one from the cycle of rebirth; enlightenment brings detachment from fame and wealth, preserving the primordial Shen (innate spiritual nature); internally observing the "Threefold Pure Precepts" (Buddhist ethical codes), while externally manifesting the "Six Perfections" (Buddhist virtues). Ultimately, one must relinquish worldly entanglements, maintain a serene heart, and roam freely beyond the azure heavens (the realm of immortals).

Overall, this depicts how Daoist practitioners, through inner refinement and meditation, attain a state transcending the mundane world, blending cultivation concepts from both Buddhist and Daoist traditions.

The fifth volume of the Huizhen Ji (Anthology of Gathering Truth) presents several passages describing the states and experiences of Daoist Neidan (internal alchemy) practice.

The first passage depicts the practitioner's condition upon reaching advanced stages: The mind becomes like a calm sea, with spiritual clarity shining brightly ("the heart-pearl luminous and pure"), transcending worldly troubles to enter a realm of serene emptiness. At this stage, the Golden Elixir gestates within ("auspiciously nurturing the elixir foundation"), radiating miraculous light ("the rainbow-hued divine radiance") capable of dispelling millennia of delusions, while the soul roams freely through Dharma realms like Qingwei Tian (one of the Three Pure Ones' celestial realms).

The Zhuan Diao Mu Lan Hua section describes the circulation of Qi within the body: The interaction of Yin-Yang energies ("coiling dragon and entwining tiger" symbolizing Yin-Yang) merges in the Dantian ("Wu Court" referring to the energy center), warming the entire body like spring snow. The practitioner's spiritual light illuminates the nine heavens like moonlight, capable of breaking through delusions and demonic obstructions. When the three Dantians ("Three Terraces"), six viscera, and eight meridians ("Eight Passes") all become purified, one attains the body of pure Yang, reaching the state of Wuwei (non-action), and freely traversing the Dharma realms.

Liu Yao Ling portrays the practitioner observing cosmic creation while pursuing the realm of Xiyi (the formless Dao), maintaining balance between firmness and gentleness. The five viscera ("five aggregates") achieve harmony, nurturing the nine Yang Qi. It describes the union of Yin-Yang ("Kun palace, Kan exchanging with Li" representing Yin-Yang interaction) as resembling a phoenix soaring or searching for a turtle in water (symbolizing the quest for true Yang). The practitioner develops jade-like bones and icy skin, with an expansive, cool form where the six spirits (sensory faculties) rest comfortably, bathed in the light of the three luminaries (sun, moon, stars), dwelling freely between cloud and sea.

Ailu Hua describes even more profound cultivation states: The mind opens completely, transcending the five senses ("five pairs") and six emotions (joy, anger, sorrow, pleasure, love, and hate). Form and spirit transform, with the head entering emptiness ("the crown becomes void"). When merit reaches perfection, the Yang spirit manifests ("birthing the Yang soul"), revealing unchanging truth that penetrates all distinctions between inner and outer. Transcending life and death in pristine formlessness, one attains the true Dharma eye (eye of wisdom), dispelling all delusions to reveal eternal pure light—perfectly bright and universally illuminating, seemingly incomplete yet wholly perfected.

These scriptures employ poetic language to describe the experiential stages of Neidan practice from foundation-building to Yang spirit liberation, embodying the Daoist pursuit of transcendental states beyond worldly existence.
