《許真君石函記》

The "Treatise on the Primordial Radiance of the Great Yang" from the first volume of True Lord Xu's Stone Casket Records primarily elucidates the generative principles of the cosmos. The Mysterious Origin of the Great Dao (referring to the cosmic source) has no fixed form in itself; it gives rise to movement and stillness through natural resonance. The manifestation of "movement" is Primordial Yang (the pre-celestial Yang Qi), which is identical to Primordial Jing (the pre-celestial refined energy). This Primordial Jing generates True Fire (pure Yang energy) that gathers and disperses within unfathomable dimensions of time and space, forming the hun and po souls. This represents the initial separation of the Great Yang.

When illumination rises from the east (Fusang denotes the place of sunrise), the nine types of pre-celestial Qi (energies) clarify and shimmer, their radiance shining upon the earth—this is the splendor of Yang brightness, manifesting as crimson light penetrating all things. Crystalline luminosity emerges in dragon-like radiance, condensing into golden clouds and jade-hued mists, while pearl-like hues and auspicious vapors fill the heavens. The scripture enumerates nine sacred lights concealed within the clouds: the Sage-Concealing Cloud Radiance, the Worthy-Concealing Cloud Radiance, and so forth up to the Fire-Concealing Cloud Radiance. These illuminations brighten heaven and earth, differentiating into various colors that nurture life.

Life originates from the primordial One (Taiji), which generates the Two (Yin-Yang), the Two generates the Three (heaven, earth, and humanity), and the Three transforms into the myriad beings. Whether in waters or on land, even in dark and filthy places, within solid stones, or among cliffs and vegetation—all creatures that run or fly, including fierce demons, arise from this process. From massive camels, oxen, and horses down to mustard-seed-sized insects, whether born through decay, gestation, or eggs—all life follows this same principle.

All beings receive distinct attributes, forming diverse appearances. They acquire different colors according to their spatial orientations: red, black, blue, white, and yellow. These emerge through the natural transformations and resonances of the Five Phases (Metal, Wood, Water, Fire, Earth), not through any post-celestial dyeing. For instance, when stones resonate with numinous Qi to generate life (transmutation through containment), they display marvelous hues like pale white, light yellow, or faint red (nurtured colors)—all formed through the wondrous operations of Qi transformation. The varying depths of an object's coloration reflect the differing intensities of heaven-and-earth Qi it has received, all being natural manifestations of the Great Dao's operations. Thus, this formless transformation and mystical metamorphosis are precisely the embodiment of the Dao.

This scripture expounds the profound principles of Daoist alchemy. It conveys how the essential energies of heaven and earth can condense into treasures, with the key lying in the harmonious transformation of yin and yang energies.

Celestial phenomena manifest corresponding forms on earth—when essences coalesce within stones, they become precious jewels. The nature of these treasures is luminous, embodying the mysteries of the Dao (the Way). Just as metal (representing the Metal phase) melts in fierce fire (Fire overcoming Metal), and forged metal tools can fell trees (Metal subduing Wood's vitality), the flourishing trees display yang energy in their outward branches (yang manifesting in spreading limbs) while harboring yin energy within (yin expressing through blossoming).

Master Xu's saying "When golden efflorescence arises, it becomes heaven-and-earth's treasure" means that the generation of metallic essence produces the supreme treasure of creation. The alchemical process mirrors natural transformations: as constellations revolve, fullness brings lush, sturdy trees (Wood's vigor manifesting as solid verdure), while waning causes blossoms to wither (flowers fading with decline). This interplay of mutual conquest between yin and yang (yin-yang interaction) reflects the Dao's natural order (the Dao's unfolding).

During alchemical practice, the phenomenon of "floating crimson powder" appears—this signifies the activation of spiritual energy (hun, the yang soul). The powder varies in crimson shades (differing red hues) and weight (varying densities). The deeper-colored, lighter particles ascend (rising like flames), forming purple frost and dark canopies that condense in the cauldron, becoming terrestrial gold. The lighter-colored, heavier particles settle, transforming through fire cultivation into golden-yellow material (fire-nurtured gossamer), representing the process of "cinnabar yang transmuting bones."

The yang soul (hun) and yin corporeal soul (po) exist in mutual dependence (hun accompanies po's dwelling, po follows hun's vitality). The hun radiates purple brilliance (hun's luminous purple splendor), while the po absorbs yang energy (gathering yang's soul-energy). When hun energy enters the po's domain (stored within po's belly), it resembles sun and moon illuminating each other, with the dragon (yang) and tiger (yin) energies devouring and merging (two energies swallowing and combining), enveloping the four directions before harmonizing at the center (uniting the four symbols, energy concentrating in the central axis).

The alchemical matter undergoes five transformations: first becoming water, then cinnabar sand, then mercury, then gold, finally forming the elixir (five changes completing the elixir). This elixir gathers heaven-and-earth's spiritual crystals (collecting creation's luminous essence), seizing the sun and moon's radiance (capturing celestial light), harnessing water and fire's energies (drawing Kan and Li's opposing forces), uniting earth's po with heaven's hun (combining earthly substance with celestial spirit). The dragon-tiger energies transform into cinnabar sand (dragon-tiger becoming alchemical cinnabar), while the sun (flying crow) and moon (running hare) incorporate their brilliance into the elixir.

True alchemical materia (the Nine-Five household's ingredients) requires understanding yin-yang harmony (symbolized by white tiger and azure dragon). Golden roots and silver stems produce yellow sprouts (yellow sprouts indicating the elixir's initial formation), filling the household with metallic radiance. This elixir prolongs life (human lifespan enduring through the ages), enabling adepts to fly through skies, traverse waters, and ride dragons or cranes (soaring through heavens, crossing waters, mounting dragons and cranes)—all manifestations of the elixir's miraculous transformations (all being its metamorphic expressions).

Finally, the text discusses harmonizing alchemical vessels (tripod and cauldron), requiring absorption of nine dragons' and red sun's vital essences (drawing nine dragons' solar marrow). Lead serves as the divine vessel (lead as numinous instrument), communicating with spirits (vessel uniting with spirit), the vessel transforming through spiritual influence (instrument changing through numinous power), until divine vessel and spirit merge into singular rest (sacred instrument and spirit harmonizing into unified repose). When natural respiration resonates (breath naturally corresponding), spirits arrive with each inhalation (spirit following inhalation's call), radiance manifesting with spiritual brilliance (light pursuing spirit's multicolored glow).

This scripture describes the mystical state of "sun and moon exchanging radiance" in Daoist Neidan (internal alchemy) practice. Through specialized breathing techniques (circulating the Wu-Ji energies throughout the twelve double-hours) and precise fire regulation (divided into the four cardinal directions and two solstices/equinoxes), the practitioner's authentic Qi (primordial energy) undergoes qualitative transformation.

During cultivation, the true Qi within the body (dragon light) undergoes wondrous metamorphosis: initially appearing as the essence within fire (the essence within flame), gradually manifesting luminosity (radiance emerging from crystalline clarity), until finally forming a blazing golden-jade circular light (the azure void's golden-jade orb light). This luminous flame can penetrate ninety thousand layers of emptiness, symbolizing the perfect fusion of yang energy (the light of Solar Majesty Yu Yi) and yin energy (the light of Lunar Grace Jie Lin).

The text employs solar and lunar movements as metaphors for cultivation principles: the sun (yang energy) rises in the east while the moon (yin energy) appears in the west, their mutual resonance between north and south (north-south correspondence) achieving the harmony of water and fire. Just as the moon itself emits no light (the Mysterious Darkness of the Great Abyss is pure black substance) but reflects solar radiance, the practitioner must also achieve elixir formation through yin-yang union (the merging of Heaven and Earth).

It particularly emphasizes that the formation of the Great Elixir (Golden Elixir) absolutely requires this state of solar-lunar radiance exchange (not the mundane mercury or cinnabar), stressing this as an energy transformation transcending material levels. Those who attain and cultivate this state (obtaining and refining it) may become "pure and authentic spiritually wondrous immortals." Yet the text laments how few truly grasp this arcane method (this Dao's true secret), with most practitioners consequently remaining adrift in the cycle of life and death (wandering through birth and death, far removed from the Dao of immortality).

This scripture elucidates the principles of Yin-Yang transformation in Daoist alchemical practice and its geographical requirements. The subtle interplay between the Great Yang (positive energy) and Great Yin (negative energy) enables the soul to ascend and the physical form to transform, achieving the most refined and numinous state. When Yin and Yang interact harmoniously, one attains sacred communion—a realm far surpassing the superficial radiance of the sun and moon.

The celestial movements of the sun and moon create seasonal cycles: at winter solstice, the sun reaches its southernmost point (Southern Lu), then gradually moves northward; at summer solstice, it arrives at its northernmost position (Northern Lu) before returning south. This north-south oscillation mirrors the Dao of life and death—after summer solstice, Yin energy grows as all things trend toward decay, while after winter solstice, Yang energy expands as renewal begins. The four pivotal junctures of the solar year (solstices and equinoxes) govern heaven-earth dynamics, with spring's birth, summer's growth, autumn's harvest, and winter's storage all following Yin-Yang's generative principles.

The refinement of the Great Return Elixir (the supreme alchemical medicine) emulates these cosmic patterns. The furnace for alchemical work must be constructed in geomantically potent land: select extraordinary mountain peaks with sun-facing slopes, where topography resembles crouching tigers and coiling dragons, embraced by layered waterways, frequented by rare birds and beasts, yet distant from graveyards and human settlements. Only such locations gather auspicious Qi (vital energy) suitable for elixir refinement.

Practitioners must mirror celestial movements to harness solar-lunar essences. Like Fuxi (the legendary emperor) who established calendars through celestial observation, alchemy requires first gentle then fierce fire control (regulating heating rhythms), adhering to the Yi Jing's (Book of Changes) wisdom. By balancing water and fire (the two fundamental alchemical elements) within the golden crucible chamber (Jinshi), Yang energy spontaneously arises.

Specifically: Yang energy stirs at the Zi hour (11pm-1am), corresponding to the Huangzhong pitch (the foundational Yang tone in ancient music theory). As Yang circulates through the Lin and Tai hexagrams (symbolizing progressive advancement), it peaks at the Si hour (9-11am). Yin energy emerges at the Wu hour (11am-1pm) with the Gou hexagram, progressing through Pi and Bo hexagrams until concluding at the Hai hour (9-11pm). This cyclical process ultimately matures the elixir like an infant completing its metamorphosis beyond the womb. The Li fire (representing heart-fire) at noon generates mercury (symbolizing spirit), while the Kan water (representing kidney-essence) at midnight produces lead (symbolizing primordial essence). Their mutual attraction and coagulation mirror the interdependent mother-child relationship.

This scripture reveals the mysteries of alchemical practice (Neidan, or internal alchemy), emphasizing that one must receive authentic oral instructions to comprehend its profound principles. The author explains that by observing the movements of the sun and moon, they penetrated the subtle transformations of heaven and earth. This cultivation method is vast and boundless—those who truly master it attain longevity equal to the cosmos itself. Thus, it must never be carelessly transmitted to unworthy individuals.

On the interplay of sun and moon (Yin-Yang): In the southernmost reaches lies a golden palace (referring to the Dantian, the body’s energy center), vast and luminous, eternally undiminished. Here, Mount Sumeru (a sacred mountain in Buddhism) serves as a metaphor for the precision of Qi circulation during cultivation, alternating between light and dark like day and night. During practice, the true Qi (vital energy) cycles through 90 trillion celestial revolutions (hyperbolically emphasizing the countless microcosmic orbits), nourishing the body’s vitality. The radiance of sun and moon shines like dragon light; fiery bright auroras connect with the divine, elevating the practitioner’s spirit (Shen) until their entire body becomes crystalline and translucent. At the peak of illumination, this light penetrates 90,000 layers of golden citadels (symbolizing the body’s meridians).

Within the Yang cavern (upper Dantian) grows a forest of blue-green trees (representing the body’s vital energy), where the divine dragon (the primordial spirit, Yuan Shen) must manifest. Hidden within is the diamond-strong golden spirit (essence, Jing), wreathed in purple mist. This purple haze signifies longevity and divine connection—a subtle resonance with the practitioner. The highest-grade purple ultimate Qi (innate primordial energy) is supremely authentic and numinous, endlessly generative. The primal crystalline Qi (Yuan Jing) is the source of all things, giving rise to the myriad energies. Qi itself is formless, guided by the spirit’s intent, weaving between heaven and earth like warp and weft in ceaseless cycles.

The text deciphers celestial motion: When the sun moves south, all things wane; when it returns north, life stirs anew. The moon’s dark path intersects the sun’s crimson orbit, while the ecliptic (earth’s path) runs between them. Practitioners must emulate this cosmic order, employing specialized methods to gather dragon crystal (innate vital essence) and tiger auroras (postnatal energy). This demands true mastery—harmonizing Yin-Yang within the body’s cauldron (Dantian), transmuting emptiness into substance. Though emptiness has no form, cultivation generates a darkness containing lead and mercury (essence and spirit); when Yang fire stirs, outward radiance appears. Once 80,000 zhang of victorious light (depicting inner luminosity) illuminates the Dantian, flowing auroras stabilize, allowing entry into the realm of absolute void.

A final warning: These are secret oral teachings of alchemy. They must be treated with utmost care—reckless transmission invites calamity.

This scripture elucidates the profound process of Five Phases transformation and Yin-Yang interaction in Daoist Neidan (internal alchemy) practice, employing symbolic language to reveal the operational principles of energy in alchemical cultivation.

The five-colored aurora circulates within the Bright Hall (referring to the upper Dantian), transforming ordinary earth into azure essence. When the firing process (huohou) is activated, it manifests as scorching red lotus radiance. As Yin qi condenses and sinks, the True Lead (referring to primordial Jing) descends into darkness; when Yang qi expands, the True Mercury (referring to primordial Shen) surfaces like shimmering silver. This purified energy can be refined into the golden-hued Golden Elixir.

When the hun and po souls stabilize and coalesce, they manifest as layers of fresh auroral light. At advanced stages of cultivation, even liquid mercury can transform into frost-like powder, demonstrating the miraculous ability to revive corpses and summon departed souls. These mysterious transformations surpass the comprehension of spirits and deities, while the subtleties of the firing process remain beyond complete mastery even by sages.

The text details the mutual engendering of the Five Phases: the qi of Bing (Fire) and Xin (Metal) transforms into True Water that nourishes the Yi-Geng Metal; the qi of Ding (Fire) and Ren (Water) transforms into True Wood that nourishes the Wu-Gui Fire; the qi of Jia (Wood) and Ji (Earth) transforms into True Earth. Serving as the "Elixir Mother," True Earth gives birth to all things, much like parents begetting offspring. These energies circulate according to the ninefold numerical patterns, mirroring the generational continuity of family lineages.

Celestial phenomena metaphorically illustrate the firing process: the Zhen trigram (representing thunder) in the East corresponds to withering elm blossoms in spring; the Dui trigram (representing metal) in the West aligns with shriveled wheat ears in autumn; the Li trigram (representing fire) in the South peaks at noon before declining, while the Kan trigram (representing water) in the North witnesses the nascent Yang qi at midnight. The sun and moon follow their respective paths—the ecliptic (solar trajectory) and lunar ninefold orbit—until their energies ultimately converge in the Divine Chamber (Dantian), completing the Golden Elixir refinement. Throughout this process, the waxing and waning of Yin-Yang and the mutual conquest among the Five Phases strictly adhere to the natural laws of the cosmos.

In ancient times, the Yellow Emperor (Huangdi) subdued rival warlords and ascended to the Purple Tenuity Star Palace (considered the celestial abode of the Heavenly Emperor in Daoism) riding a dragon. His seventy-two ministers transformed into feathered immortals, stepping upon rosy clouds to rise into the celestial realm, entering the golden city of immortals where they roamed freely through the cinnabar skies (Danxiao, the heavenly firmament of the immortal world). Thus they became true transcendents, having received elixirs from divine lords and followed phoenix-drawn chariots past Mount Emei.

The path of cultivation is never easy: thatched huts appear crude without trimming, mountain trails choked with thorns pierce the clouds, and Emei's perilous ridges defy climbing. They reverently invited the August One (referring to the Yellow Emperor) to return at dusk, never practicing those petty heterodox arts—never believing saliva could be refined into golden elixirs, never distilling urine into autumn stones (a pseudo-Waidan substance), never promoting starvation techniques, never practicing shoulder-shaking breath-counting exercises, never engaging in eye-closing mental tricks, never boasting that hand-grasping techniques could capture demons, never discussing shadow-nourished spiritual entities, and certainly never teaching licentious arts. The true Great Dao of immortality is the supreme path, yet worldly seekers refuse to follow it, and ordinary people disbelieve when told—all becomes clear after reading the biography of Xu Jingyang (the perfected lord Xu Xun).

Regarding the "Medicine Mother": the alchemical path doesn't use ordinary metals, minerals, cinnabar or mercury—these tangible substances. It's formless, merging with emptiness to ultimately achieve the realm of true void. This authentic void-body constitutes the foundation of returned elixir (Neidan) and the root of the great medicine (Golden Elixir). What is the essence of the Medicine Mother? It originates from the numinous quality within primordial chaos, existing even before the Heavenly Emperor. The innate true void harmonizes with nature, manifesting as material forms (sexiang) transformed through divine operation. Though the true void operates, it never falls into emptiness—this profound mystery connects with divine intelligence, manifesting as mysterious black hues representing the hidden virtue (De) of the Dao's origin (Xuan Yuan). The Dao's profound virtue resembles an abyss—this vast depth is called the Northern Ming (dark northern sea), whose boundlessness corresponds to the limitless Great Dao. From this Wuji (Ultimateless) Dao emerges Taiyi (Supreme Unity), the primordial essence that after six million years generated all things, which ultimately return to the Dao's governance. That which generates all things is the Elixir Mother, appearing as lead-black. Why does blackness achieve true water? Because the six primordial qi of the north (innate water essence) align with celestial rulers above, while below they manifest as five-colored lead essence—these colors transforming into blue, yellow, white, red and black, with black being the foundation of Xuan Yuan's true water. Water is the pivot of the Dao, its essence being the true unitary qi within the Kan trigram (water symbol of the Bagua), this energy resonating with the dazed chaos of the primordial state.

This passage elucidates the principle of Yin-Yang interaction in alchemical practice, focusing on the profound process of water (Kan trigram) and fire (Li trigram) energies interacting.

Initially, when Yin and Yang energies stimulate and resonate with each other, they appear formless and intangible (Xu, "emptiness"). Yet, it is precisely within this emptiness that substantial reality emerges. This is symbolized by the sun and moon in a gourd: water’s nature is moist and descending, while fire’s nature is scorching and ascending. When these two forces collide—water extinguishing fire—the extinguished fire transforms into earth, from which metal (metal phase) is born. Metal then generates water, creating a cyclical process of mutual production.

The text particularly emphasizes the mystery of metal-water mutual generation: metal produces water, and water nourishes metal in return. This cycle refines the practitioner’s skin until it becomes jade-like in radiance. The key to alchemy lies in mastering the "measure of one jin" (an ancient unit of weight), perfectly balancing the Yin and Yang energies of the waxing and waning moons (eight liang each, totaling sixteen liang—one jin). This harmony mirrors the cosmic structure formed by the interaction of the Qian (Heaven) and Kun (Earth) trigrams.

The alchemical process unfolds through six transformations of the Qian (three solid Yang lines) and Kun (three broken Yin lines) trigrams, where Yang (white) and Yin (black) energies mutually convert. Within Yin, the Yang "yellow sprout" (an early-stage alchemical product) is cultivated. From this sprout emerges mercury (quicksilver), which then exhales the "Three Flowers" (manifestations of Jing, Qi, and Shen). These ultimately condense into cinnabar. Consuming this Golden Elixir (Jindan) for a hundred days refines the body, transforming mortal flesh into indestructible metal and stone, achieving the state where form and spirit are sublimated—a realm of immortality.

Ultimately, the mystery of the Golden Elixir lies in "generating being from non-being." Its transformative principle corresponds to the convergence of the Zhen (thunder), Dui (lake), Kan (water), and Li (fire) trigrams. Yet these subtle workings of primordial essence (Yuanjing) defy visual depiction, as they embody the fusion of formless Qi and the Dao’s boundless emptiness.

This passage explains the core principles and life transformation process in Daoist alchemy. The natural transformations of cinnabar (the primary material for alchemy) contain the profound mysteries of cosmic creation. Here, the Dui trigram (representing the youngest daughter) from the Bagua symbolizes the spiritual nature of cinnabar. Dui corresponds to the western metal position in the Five Phases, where metal serves as the father of all things and water as their mother.

The key to alchemy lies in balancing water and fire: excessive fire will melt metal, which then transforms into water and flows northward, nourishing the eastern wood energy (represented by the Zhen trigram). This creates the symbolic meeting of dragon and tiger. The western metal position (Geng and Xin) corresponds to the White Tiger, requiring the harmonization of Yin and Yang so that Yang is contained within Yin—much like moonlight reflecting sunlight to produce a violet radiance. This luminous energy connects the three realms of heaven, earth, and humanity, just as the rising and falling of water and fire create seasonal changes, and the cyclical movements of sun and moon sustain cosmic order.

The materials used in alchemy—cinnabar, mercury, and lead—share the same origin, all being transformations of the same "spiritual seedling" (primordial Qi). Through twenty-four refining cycles (symbolizing the twenty-four solar terms) in the alchemical cauldron, the process culminates in the "Flower Pool" (the alchemical vessel) producing snow-white elixirs (Divine Talisman White Snow), said to revive the dead. Yet people often doubt: how can life return once the soul has scattered after death?

In truth, "soul retrieval" does not mean reviving a decomposed corpse but rather recovering the innate "celestial soul" (original spirit) through cultivation. Just as all beings—humans, animals, birds, and insects—are born from their parents' primal essence (innate Jing and Qi), each endowed with distinct nature and life. The soul, composed of metal essence, forms the foundation of life, while the corporeal soul, belonging to Yin's obscurity, sustains physical form. Only when nature and life are interconnected does complete existence emerge. Alchemy replicates this very process of life generation.

This passage elucidates the core principles and states of attainment in Daoist Neidan (internal alchemy) practice. The opening describes the primordial life energies of Hun (ethereal soul) and Po (corporeal soul) merging in a state of profound subtlety, where the refined energies of Yin and Yang (the Two Qi) give birth to all things, harmonizing with Heaven and Earth (Qian and Kun).

The grand creativity of Heaven and Earth hinges upon the gateway where Yin and Yang intersect. Just as the essences of sun (crow essence representing the sun) and moon (hare marrow representing the moon) nourish each other, human Hun and Po connect like roots and branches. Through the dual cultivation of nature and life (where "nature" refers to the innate Shen/spirit and "life" to acquired Jing/essence and Qi), refining the Hun and Po coalesces into the divine elixir (Neidan).

Authentic cultivation doesn't rely on talismans (shenfu) or Waidan (external alchemy, symbolized by "white snow"). Merely using cinnabar (a Waidan ingredient) proves ineffective. Only Neidan practice enables true transformation (returning yang and replacing bones) to achieve genuine immortality. The text particularly emphasizes the profound mystery of "divine talismans with white snow," pointing to the supreme method combining internal and external practices.

The passage then depicts inner alchemical phenomena: lead and mercury (true lead representing original essence, true mercury representing original spirit) interact like dragons and tigers, their radiance resembling the primal separation of chaos during Pangu's creation. The luminous essences of the Green Dragon (liver Qi) and White Tiger (lung Qi) mutually stimulate, gathered into the Dantian (Peng Hu, the alchemical cauldron) to form a radiant energy core. This core shines like a precious moonstone, with five-colored light circulating, water and fire (Kan and Li) merging like conjoined sun and moon, and the Five Phases (five stars) aligning like strung pearls.

At the pinnacle of cultivation, various auspicious signs manifest: the Southern Pole Elder Star (star of longevity) appears amid purple vapors (auspicious Qi). Within the cauldron (Dantian), energy crystallizes like frost and snow, forming coral-like meridian networks. As Yang energy expands and Yin diminishes (completely stripping away all Yin), the ultimate Ninefold Purple-Gold Elixir (highest grade Neidan) is forged.

Finally, five types of auroras (morning glow, evening glow, setting glow, flying glow, and fiery glow) symbolize different cultivation stages, while five sacred cinnabars (auspicious cinnabar, vast spirit cinnabar, purple spirit cinnabar, myriad spirit cinnabar, and treasure cinnabar) demonstrate miraculous effects—including turning stone to gold and universal salvation—depicting the various supernatural abilities attained through perfected Neidan.

This passage primarily elucidates the methods and principles of refining the "Five Numinous Cinnabars" in Daoist alchemy, along with the fundamental principles of Heaven-Earth and Yin-Yang interaction.

Regarding the refinement of the Five Numinous Cinnabars: The Purple Divine Cinnabar transmitted by the Supreme Mysterious Primordial Sage (a revered Daoist deity) requires five refinement stages across twenty-four cauldrons. Through continuous addition of water and fire elements, combined with twelve divine talismans (fulu) and ninefold refined white snow (an alchemical term denoting pure elixir essence), nine years of repeated refinement are necessary for success. The elixir's preparation must strictly follow the transformations of Yin-Yang without the slightest deviation. The process must align with 8,640 hexagram transformations, particularly the application of the Qian (Heaven), Kun (Earth), Kan (Water), and Li (Fire) trigrams—where Li represents fiery ascension and Kan represents watery descent, requiring their harmonious interaction.

The scripture emphasizes this elixir's supreme efficacy: a single pellet can manifest infinite transformations, capable of prolonging life while blessing entire households. Through diligent practice, adepts may ultimately receive divine summons to ascend to the Great Canopy Heaven (Da Luo Tian, the highest Daoist celestial realm).

The second part discusses alchemy's foundational principles: the way Heaven (Qian) and Earth (Kun) interact to generate all things. Should Heaven-Earth's operation fail to maintain the complete cycle of Yuan (Origination), Heng (Prosperity), Li (Advantage), and Zhen (Perseverance) — the Four Virtues from the Yijing — it would violate natural law. Yang qi cannot expand, Yin qi cannot germinate, and the qi of Heaven and Earth cannot commingle, depriving all beings of their growth foundation. This mirrors alchemical failure when impure ingredients or improper firing temperatures are used—even with fire application, success remains unattainable.

This passage elucidates the profound relationship between material transformations and Yin-Yang dynamics in alchemical practice. If the alchemical method is incorrect, the talismans (Fulu) lose efficacy, the medicinal substances become impure, and even wind and clouds refuse to harmonize. Without the assistance of tiger-like forms and dragon radiance, how could cinnabar—the primary alchemical ingredient—naturally manifest?

Authentic elixirs require mutual transformation among substances, which in turn generate new materials during refinement. The Golden Azure Scripture (Jinbi Jing) states: Eggshells can transform into golden essence (Jing), and water can revert to yellow liquid—such are the wondrous metamorphoses of alchemical ingredients. During these transformations, flames leap with radiant light, revealing extraordinary phenomena: the "flowing pearls" (mercury droplets) coalescing like solar essence, dewdrops merging into streams, then crystallizing into frost, ultimately forming coral-like structures or osmanthus-like branches.

This process is called the "Reclining Moon Spirit Fungus" (Yanyue Lingzhi), born from the mutual nourishment of Yin and Yang. Like the moon's waxing and waning, when light diminishes to its extreme (the ninth exhaustion), new brilliance emerges; when darkness peaks (the sixth birth), it heralds the beginning of Yin's resonance. This mirrors the transformations of the second and third Yin lines (Liu’er, Liusan) in the Book of Changes (Yijing), symbolizing the fundamental cycles of heaven and earth.

During alchemical refinement, substances naturally attract radiant clouds and auroras, as if summoning solar essence to nurture divine medicine. When the five tones harmonize and the six pitch-standards alternate, cinnabar glows vermilion like agate. This demands precise fire regulation: the Vermilion Bird (southern fire) governs the process, allowing Wood Qi (Jia-Yi) to nourish Fire Qi (Bing-Ding), while Western Dui-metal transforms into golden essence. Metal begets water, water regenerates metal—forming an endless cycle of mutual engenderment.

The most mysterious state is the "Golden Embryo and Water Mother" (Jintai Shuimu)—where metal and water gestate in the crucible like a womb. During the fiery-water refinement, substances alternately float (appearing as white mercury-sand) or sink (precipitating as black lead-water), their fluctuations unfathomably profound. As the Supreme Dao Ancestor (Taishang Daozu) proclaimed: True creation often lies beyond form, manifesting only at appointed hours—at midnight (Zi), shimmering like fish scales; at noon (Wu), congealing like hoarfrost; at dawn (Mao), glowing like flawless jade.

This scripture primarily expounds on the cosmological framework and alchemical principles in Daoist Neidan (internal alchemy), integrating celestial phenomena, the Five Phases (Wood, Fire, Earth, Metal, Water), and the Bagua (Eight Trigrams) with practical alchemical cultivation.

It begins by delineating the correspondence between the Four Symbols (Azure Dragon, Vermilion Bird, White Tiger, Black Tortoise) and the Twenty-Eight Lunar Mansions: the eastern direction (associated with the Heavenly Stems Jiǎ and Yǐ and the Wood phase) aligns with the Azure Dragon's seven mansions (Jiǎo, Kàng, Dī, Fáng, Xīn, Wěi, Jī); the southern direction (Bǐng, Dīng, Fire) with the Vermilion Bird's seven mansions (Jǐng, Guǐ, Liǔ, Xīng, Zhāng, Yì, Zhěn); the western direction (Gēng, Xīn, Metal) with the White Tiger's seven mansions (Kuí, Lóu, Wèi, Mǎo, Bì, Zī, Shēn); and the northern direction (Rén, Guǐ, Water) with the Black Tortoise's seven mansions (Dǒu, Niú, Nǚ, Xū, Wēi, Shì, Bì), each symbolically represented by the hybrid turtle-serpent imagery.

The text then explains the harmonization patterns between the Bagua (Qián, Kūn, Zhèn, Duì, Xùn, Gèn, Lí, Kǎn) and the Heavenly Stems (Jiǎ, Yǐ, Bǐng, Dīng, etc.). For instance, Qián trigram corresponds to Rén and Jiǎ, while Kǎn encompasses six Wù stems. Within the transformations of celestial Yin-Yang, Kūn gives rise to Zhèn and Duì, Qián generates Xùn and Gèn, with the Eight Trigrams evolving from Qián as their origin, while the Ten Heavenly Stems unite with celestial primordiality.

The essence of alchemy lies in mastering these cosmic patterns. The text describes refining cinnabar in the cauldron to transmute mercury into gold, ultimately producing the Great Return Elixir (the supreme alchemical medicine in Daoism). Ingesting this elixir not only benefits humanity but enables ascension to immortality, liberating practitioners from the Three Realms (Desire, Form, and Formlessness) and transcending the constraints of the Five Phases, achieving the autonomous state of "my destiny rests with me, not Heaven."

Particular emphasis is placed on the fundamental unity of alchemical materials like cinnabar, mercury, and lead-silver despite their differing forms. Comprehending their profound mysteries to refine the priceless elixir grants longevity equal to Heaven and Earth. The text concludes by urging students to treasure these principles, contemplate them deeply, and regard this knowledge as a guiding mirror for alchemical practice.

The appended Cinnabar Path Attestation Verse succinctly summarizes: "The nameless is the origin of Heaven-Earth; the named is the mother of all things." By gathering Yin Qi to form the earth and accumulating Yang Qi to create the heavens, one masters the patterns of the Three Powers (Heaven, Earth, Humanity), aligning cinnabar refinement with the natural Dao. This constitutes the wondrous formula transmitted to truth-seekers.

This scripture expounds the core principles of Daoist alchemy, detailing the process and rationale behind refining the Golden Elixir (Jindan). The opening term "Kunzhen" refers to the pure Yin energy of the earth, while "Zhengde" represents the pure Yang vital force—their fusion generates spiritually potent substances. In alchemical practice, cinnabar (known as "Taiyi gold") serves as the primary ingredient, combined with mercury (the "mother of mercury"), and refined through the essence of solar Li fire (symbolizing pure Yang energy) within the mystical space called the "Xiyi Mansion" (referring either to the Dantian or the esoteric dimension of the alchemical furnace).

Five extraordinary phenomena manifest during the refinement process: purple-gold radiance, snow-like white crystals, celestial valley azure, lead-black liquid, and central yellow essence. The successfully forged Golden Elixir enables complete bodily transformation—curing all ailments, restoring youth, turning white hair black, making teeth shine like silver, and granting night vision. However, practitioners must not covet these marvels but maintain reclusive cultivation while accumulating hidden virtue (Yinde). The text particularly emphasizes aiding the needy: healing the sick, providing material assistance to the poor ("yellow-white" denoting gold and silver), and imparting alchemical secrets to sincere students.

The latter section focuses on timing in alchemical practice. One must strictly follow natural rhythms: the interplay of water and fire must accord with celestial cycles (Tianfu), and seasonal temperatures must harmonize. If winter becomes summer-hot, summer brings unseasonal frost, or if the water-clock's rhythm and day-night cycles become disordered, these signal disrupted Yin-Yang balance. When "Kun fire" (earth fire) weakens, Yin energy invades while Yang qi diminishes—like overlogged forests where Yin and Yang fail to mutually generate and restrain, or like the misaligned celestial mechanism (Xuanji referring to the Big Dipper). Under such conditions, alchemy inevitably fails.

The text concludes with an admonition: these principles require ten thousand contemplations ("ascending the celestial ladder" metaphorically represents spiritual progress), yet true understanding lies not in empty theorizing but diligent practice. Through this "Stone Casket Record," the Perfected Lord Xu Xun (revered Jin dynasty Daoist and founder of the Jingming tradition) condensed profound alchemical wisdom into practical instructions, emphasizing the unity of knowledge and action as essential to Daoist cultivation.

This scripture elucidates the core principles and miraculous effects of Daoist Neidan (internal alchemy) practice. It begins by revealing that all transformations in the phenomenal world originate from the interaction of "cinnabar and mercury" (fundamental alchemical substances), just as the rising sun (golden crow) emanates light from the Fusang tree in the east. This solar fire is called "hun" (ethereal soul), symbolizing the vital life force.

The text describes the cyclical patterns of alchemical practice: like the sun's daily ascent and descent or the moon's waxing and waning phases, practitioners must circulate their Qi (vital energy) as if steering the "Chariot of Solar Radiance" (metaphor for internal energy movement). Upon reaching advanced stages, "true jing" (primordial essence) manifests—an energy capable of penetrating stone, melting metal, and illuminating heaven and earth with its brilliance.

The authentic Golden Elixir isn't produced by smelting metals and minerals (Waidan/external alchemy), but emerges from emptiness as "returned elixir" (Neidan), luminous like a night-shining pearl. Using Bagua (Eight Trigrams) symbols—Kun (earth), Zhen (thunder), Dui (lake), Qian (heaven)—the text illustrates the cyclical transformations of Yin-Yang energies within the body, with this alchemical achievement called "purple-gold ointment" (supreme elixir).

Five miraculous powers of the Golden Elixir are then enumerated: restoring sight to the blind, regenerating flesh on dry bones, transforming ordinary stones into gold, converting rivers into milk, and preserving eternal youth. It can even transmute common tiles into gold and cure incurable diseases. Yet ignorant seekers mistakenly search for elixir ingredients within their physical bodies, failing to understand the true elixir emerges from the harmonious union of Yin-Yang energies. When essence and Qi dissipate, the hundred spirits scatter and the body decays.

The conclusion emphasizes that authentic practice involves refining "golden liquid" (liquid form of the elixir), revealing this as the fundamental Dao existing since Pangu created heaven and earth. Using Wuxing (Five Phases—Wood/Jia-Yi, Metal/Geng-Xin) and Sixiang (Four Symbols including Vermilion Bird), the text explains how alchemy requires the harmonious interaction of Yin-Yang and the perfect balance of water-fire. The "Three-Five-One" formula refers to the crucial unity of the three Dantian (energy centers) with the Five Phases, highlighting the generative principle of heaven-earth-human triad.

Practitioners must first recognize "true lead" (primordial essence), the foundational material for alchemy. The phrase "heaven contains five thieves" refers to the mutual conquest principle of the Five Phases, while authentic lead (primordial essence) radiates five-colored light—the celestial essence born from primordial emptiness.

This scripture describes the mystical transformation process of "lead" (a Neidan term referring to primordial Qi) in Daoist alchemy, and how to refine it into an elixir of immortality through cultivation.

In the beginning, the origin of all things (Xuan Yuan) was concealed within chaos. When the most refined Qi activates Yang energy, it produces lightning-like radiance. This light spirals and divides into five colors, within which lies lead essence unrecognizable to ordinary people. It thrives like spring vegetation, pure as summer ice, never forming frost in autumn nor accumulating snow in winter. Nourished in harmony, it gradually attains spiritual potency. This substance, called "Yellow Sprout" (a Neidan term for true primordial lead), is entirely distinct from worldly lead.

After eight hundred years of gestation, the Yellow Sprout transforms into "blue mercury" (a term for the initially refined essence), and after another eight hundred years, it becomes "blue gold" (a higher-stage alchemical product). Blue gold is fundamentally the bone of the Azure Dragon. After undergoing specific cycles of transformation, it eventually ascends to the celestial realm as luminous dust, becoming the blessing and fortune of immortals. When it rises into the heavenly palaces (such as Qingdu, Ziyang Palace, and Zhaoyang Hall—sacred Daoist realms), it emits boundless crimson light, with lead Qi splitting into five-colored flames.

Immortals nourish themselves by inhaling this lead Qi, while jade boys and maidens consume its radiance, granting the celestial host endless longevity. This divine lead differs from ordinary lead—it floats in the air, shining brilliantly, capable of penetrating crystal palaces, within which resides the true form of the "golden rooster" (symbolizing pure Yang). When wind and clouds converge, and dragon and tiger unite (representing the fusion of Yin and Yang Qi), it condenses into the true elixir of immortality.

Ingesting this elixir enables instantaneous ascension, transforming one's physical form until the countenance resembles that of the Celestial Worthy of Primordial Beginning (Yuanshi Tianzun, the supreme deity of Daoism), sharing the same origin as heaven and earth. The scripture emphasizes that this cultivation method is entirely distinct from ordinary gold-and-cinnabar alchemy. In the mundane world, lead essence is the foremost of the five metals and the mother of seventy-two minerals. Practitioners must first purge its Yin turbidity, refining lead sand into earthen lumps sealed with "Six-One Mud" (a material used in alchemical sealing). After a day and night of smelting, the lead melts into "divine water" (the refined essence of alchemy).

This scripture elucidates the mysteries and taboos of Daoist alchemy, divided into two sections: "The Primordial Origin of Divine Water" and "The Perfect Illumination of the Divine Chamber."

The first half explains that the key alchemical ingredient, "Divine Water" (a technical term referring to the essence of mercury), originates from white gold. This white gold is not ordinary metal but rather mercury in its essential state. Through specialized methods that return mercury to its primordial source, one can refine the Great Elixir of immortality. However, it sternly warns that this cannot be achieved with common mercury—it requires unique refinement techniques. Those who covet wealth, indulge in sensual pleasures, or violate precepts will face divine punishment, condemned to endless suffering in Fengdu (the Daoist underworld). These alchemical secrets must never be casually disclosed to unworthy individuals, lest it bring calamities beyond redemption.

The latter half details the protocols for constructing an alchemical altar. To refine the Great Elixir, one must select an auspicious site with favorable feng shui and build a three-tiered ritual platform according to strict specifications:

• The upper tier stands twelve chi (an ancient unit of measurement) high, arranged according to the Nine Palaces (the Daoist cosmological model of nine cardinal directions).
• The middle tier measures fifteen chi high, divided according to the Bagua (Eight Trigrams representing directional energies).
• The lower tier is twelve chi high, featuring eight gates (entry points).

The altar must be fortified with swords hung to guard the four directions, bronze mirrors to ward off malevolent forces, and five-colored banners. At its center stands the "Divine Furnace" (alchemical crucible), where the "Divine Chamber" (alchemical vessel) is nurtured through precise fire control. This egg-shaped Divine Chamber fluctuates with lunar phases and operates in tandem with the golden cauldron (alchemical apparatus). The text concludes by emphasizing that placing the cauldron and preparing the ingredients demand extraordinary skill.

This passage describes the chaotic state caused by the imbalance of Yin and Yang in Daoist Neidan (internal alchemy) practice, and how to restore harmony by adjusting the "cauldron" (referring to key energy centers in the body). When cultivation methods deviate from the proper path—like a tilted cauldron or misaligned Mingtang (upper Dantian)—the interplay of Yin and Yang energies (represented by Kan and Li, the water of the kidneys and fire of the heart) becomes disrupted. This is likened to the sun and moon failing to meet, the exhaustion of metal and water (lung and kidney energies), and practitioners missing their optimal timing.

The text employs rich symbolism to depict this imbalance: the Dragon and Tiger (Shen/spirit and Jing/essence) vanish, the "killing qi" (purging energy) dissipates, and the golden embryo (nascent Golden Elixir) cannot form. To rectify this, one must act like a master craftsman by reestablishing the positions of Qian (Heaven) and Kun (Earth), regulating Yin and Yang within the cauldron (Dantian) to realign the "sun and moon" (Yin-Yang). When metal and wood (lung and liver energies) interact, and water-fire (kidney and heart qi) achieve mutual nourishment, the energies of the four directions converge in the golden cauldron (lower Dantian), allowing the auspicious meeting of Dragon and Tiger in the profound darkness (the state of primordial chaos).

The latter section vividly portrays the signs of successful practice: light emerges from chaos as the refining of Geng metal (western metal qi) and the "young maiden" (pure energy symbolized by the Dui trigram) forms the "divine chamber" (abode of the spirit). When this chamber brightens, the Shen moves freely, uniting with primordial qi. This alchemical process ultimately merges spirit with the Dao, requiring adherence to the principles of the Yinfu Jing (Scripture of the Hidden Talisman) and observation of celestial patterns—such as the alignment of the Milky Way, the movements of the Twenty-Eight Lunar Mansions, the convergence of fire and water constellations (Southern and Northern Dippers), and the呼应 of the White Tiger and Azure Dragon (western and eastern asterisms).

The conclusion paints a poetic vision of the Golden Elixir's completion: like a tiger's roar summoning wind or a dragon exhaling clouds, radiant hues condense into pearl-like particles. The "Golden Duke" (lead, symbolizing primordial Jing) unites with "yellow sprouts" (the elixir's first manifestation), refining into "white snow" (pure Yang qi) and "purple sand" (materialized elixir), circulating endlessly like "Azure Dragon ointment" (a metaphor for the perfected elixir). The entire process emphasizes the harmonious interplay of Yin and Yang and the integration of the Five Phases, culminating in the sacred union of spirit and Dao.

This alchemical formula describes the mystical process of refining the "Dragon's Marrow and Tiger's Brain" elixir of immortality. During the alchemical process, "red powder" (cinnabar) must be combined with "White Tiger" (lead and mercury) in precise ratios under controlled heating, ultimately forming a radiant golden elixir. This elixir not only possesses the power to transmute stone into gold but can restore youth to the aged.

Within the crucible (the "Hall of Eternal Life"), the medicinal substances undergo refinement through the essence of sun and moon. When the "Celestial Pillar" (the furnace's central axis) shines brightly, the two Qi of Yin and Yang (hun and po souls) intermingle like the toad and jade rabbit spirits merging within the moon palace. The mercury (personified as Heng'e, the moon goddess) flows like moonlight within the vessel, ultimately transforming into the resplendent Golden Elixir.

Perfecting the Golden Elixir requires precise control of water-fire interaction: cinnabar (Li fire) and lead-mercury (Kan water) dance like soaring dragons and leaping tigers within the crucible—sometimes manifesting as violet-golden mists, other times condensing into translucent golden crystals. When complete transformation occurs, the substance emits an azure-jade luminescence, at which point the "Spiritual Cinnabar" (elixir essence) sheds its impurities, revealing its numinous transformative power—condensing into form or dispersing into nothingness.

The formula particularly emphasizes the principle of "lead-mercury communion": lead (true lead) acts as the father while mercury (true mercury) serves as mother—their union within the crucible gestates the Golden Elixir. As the Dao De Jing states, "The universe had a beginning, which is the mother of all things"—alchemy must follow this fundamental law. At the furnace's most intense stage, the substances produce extraordinary sounds as water and fire interact, separating and purifying lead from mercury until black impurities fade, revealing pure white elixir radiance.

Most wondrous is the elixir's numinous transformations: it can shine like the sun yet remain formless as primordial Qi; it penetrates metal and stone yet traverses the Celestial Gate (indicating the elixir's energy connecting heaven and earth). This Golden Elixir is both material crystallization and cosmic essence condensation, thus possessing the miraculous efficacy of "ten-thousand-year sacred flame."

This passage elucidates the profound process of Yin-Yang interaction and Five Phases transformation in Daoist Neidan (internal alchemy) practice, using the interplay between celestial hun (heavenly soul, representing Yang Qi) and earthly po (earthly spirit, representing Yin Qi) as metaphors for alchemical principles.

The celestial hun belongs to Yang while the earthly po belongs to Yin, interdependent like ancestral lineages. The Zi hour (midnight) corresponds to Water and the Wu hour (noon) to Fire—when these opposing forces interact, they generate the central Earth element. The union of two Earth elements produces "guiding silver" (an alchemical term denoting purified metallic essence), which further transforms into the Golden Elixir (Jindan). The central lines of the Li trigram (symbolizing Fire) and Kan trigram (symbolizing Water) resonate with each other, their respective brilliance and essence mutually concealing yet illuminating one another.

This state of Yin-Yang fusion facilitates an energetic exchange between Metal and Fire, mirroring how the sun (Li as feminine) and moon (Kan as masculine) illuminate each other. When feminine energy enters masculine energy, infinite transformations become possible. The "sacred sun and sacred moon" mentioned refer to the Yin-Yang energies generated within the practitioner's body during cultivation—these energies circulate subtly until ultimately refining into the purple spiritual medicine (Neidan). This numinous substance possesses supernatural potency, resonating with Yang Fire (the primordial Qi during practice) to transform into radiant light that permeates the entire body.

During the alchemical process, the jade mushroom (incipient form of the elixir) manifests crimson hues through rosy light—the deeper the firing process, the more intense the red coloration. The "two luminaries" denote the Wood and Metal elements: the Zhen trigram (symbolizing Thunder) in the East belongs to Wood which generates Fire, while Zhen also represents the dragon (Yang Qi); the Dui trigram (symbolizing Marsh) in the West belongs to Metal and contains the generative properties of Metal-Water interaction, with Dui representing the tiger (Yin Qi). When dragon and tiger (Yin-Yang) meet, they merge as swiftly as wind and rain, ultimately forming the golden essence (quintessence of the Golden Elixir).

This supreme Golden Elixir medicine embodies the mystery of Five Phases mutual generation: the sacred water (kidney essence) and sacred fire (heart fire) interpenetrate, containing water within fire and metal within water. The Yang mercury (original spirit) absorbs metal Qi (original essence), while the Zhen trigram (Wood) combines with the Geng-Xin (Metal) in the You position (West). Practitioners employ the Yang Dun method (celestial circuit cultivation) through sixty Jiazi cycles (five days constituting one phase), commencing from the Zhen trigram and concluding with the Dui trigram to complete the Yin-Yang transformation. Just as the moon manifests its half-circle when reaching the Ding position (South), during the Metal-Fire interaction, the Dui trigram (Metal) combines with the six Ding (Fire), following the generative sequence of Fire begetting Earth and Earth begetting Metal, ultimately refining the Golden Elixir.

This scripture elucidates the principles of "trigram fire celestial cycle" (guahuozhoutian) in Daoist Neidan (internal alchemy) practice, using the Bagua (Eight Trigrams) from the Yijing (Book of Changes) to symbolize the operational patterns of Yin-Yang energies.

The text begins with the natural transformation between Qian (pure Yang) and Kun (pure Yin) trigrams: when Yang energy reaches its zenith, it transitions into Yin, and when Yin energy culminates, it reverts to Yang. Qian is represented by the number nine, signifying the ultimate Yang number, while Kun is denoted by six, the ultimate Yin number. Through the changes of the second and third Yin lines (six-two and six-three), after three stages, the third Yang line (nine-three) is formed—akin to maintaining vigilance at dusk ("xi ti"), which ultimately achieves the perfected state of the Qian trigram.

Next, it describes the cyclical movement of Yang energy: the eastern direction and the Jia Wood phase correspond to the six Jia (a Daoist temporal unit), with the Qian trigram governing five Yang days to form a climatic cycle. After sixty double-hours (shichen) of Yang energy circulation, it transitions into the Yin retreat phase (a period dominated by Yin energy). The first thirty-five cycles accumulate one hundred and eighty shichen, symbolizing the progress of half a year’s cultivation.

The text then explains the Yin-Yang transformation: when Qian energy peaks, Yin energy begins to emerge, and Yang recedes, transforming into the Xun trigram (Wind trigram). Xun governs the Yin talismans (Yinfu), and Kun’s first Yin line (six-one) starts to form. From the sixteenth to the twenty-sixth shichen, Xun energy gradually shifts into the Gen trigram (Mountain trigram). Xun also operates in five-day climatic cycles, and after sixty shichen, it enters the upper Yin retreat phase.

Subsequently, the transformation from Gen to Kun is described: Gen corresponds to the six Bing days, inheriting Xun’s energy. As Yin energy grows stronger, the interplay of Water and Fire energies shifts. On the twenty-third day, the waning moon phase begins, and Gen’s Fire naturally diminishes. After sixty shichen of Gen’s operation, it transitions into the middle Yin retreat phase, ultimately forming the pure Yin Kun trigram, corresponding to the Yi and Gui days, symbolizing the completion of a thirty-day cycle.

The text concludes by summarizing the entire cultivation cycle: through six phases (thirty days) of Yin-Yang alternation, it mirrors the annual cycle of seasonal changes. The one hundred and eighty shichen of Yin-Yang circulation represent half a year, while the waxing and waning moons symbolize a complete annual cycle. A year is divided into twelve solar terms, with each month’s six phases completing a minor celestial cycle. The innate primordial Qi (Xiantian Yuanqi) merges with acquired cultivation, and after approximately thirteen thousand refinements of fire phases (about three years), the "Flowing Pearl Elixir" (Liuzhu Dan) is achieved. At this stage, the alchemical cauldron (the human body) gathers Yang energy like a luminous mirror, with radiant light within the cauldron resembling dawn’s glow. The spirit (Shen) and the cauldron unite, attaining the supreme state of "divine intoxication in luminous rapture."

Note: In this text, "talisman fire" (Fuhuo) refers to the regulation of fire phases in Neidan practice; "Flowing Pearl Cauldron" (Liuzhu Ding) metaphorically represents the human body as an alchemical furnace; and "spirit chamber" (Shenshi) denotes the upper Dantian (the cranial region for cultivation).

This scripture describes the profound states of Daoist Neidan (internal alchemy) practice, using lunar phases as metaphors for the elixir refinement process. Practitioners harmonize their Shen (spirit) and Qi (vital energy) to enter a trance-like state ("spiritual intoxication"), during which inner radiance circulates like a polished mirror, while the firing process resembles golden millet grains scattering across a crystal plate (alchemical terminology referring to the nascent form of the Golden Elixir). The waxing and waning moon symbolizes the ebb and flow of Yin-Yang energies within the alchemical cauldron: the full white moon represents the flourishing of Yang energy, while the dark new moon signifies Yin's dominance.

Particular emphasis is placed on the mystery of "primordial chaos energy" (Hongmeng, the pre-celestial Yuanqi), ingestion of which enables bodily levitation. The author stresses that true cultivation transcends worldly understanding, revealing the philosophical insight that "emptiness is form," while comparing the fusion of solar essence (Yangjing) and lunar effulgence (Yinhua) to the supreme grade of elixir. The text ultimately clarifies that the essence of practice lies in liberation from the constraints of the Five Phases to attain ultimate freedom.

The "Treatise on the Golden Cauldron's Non-Being" section records ancient alchemical secrets, noting that heaven and earth's spiritual nature originates from the primordial interaction of yellow and black energies (the foundational Yin-Yang). The "primordial chaos" (Mingxing) constitutes the root of Dao cultivation. The golden cauldron (core alchemical vessel) emerges from the nameless, formless state of the Great Beginning. Practitioners establish their life foundation by gathering "golden essence" (pre-celestial metal energy), which manifests as the "jade pond" (an alternate name for the Dantian) containing divine water. Through poetic alchemical metaphors, the entire text reveals the isomorphic relationship between internal alchemy and cosmic generation.

This scripture elucidates the core principles of Daoist Neidan (internal alchemy) practice, using metal (gold) along with water and fire as symbols to describe the alchemical process of Yin-Yang transformation. The "golden essence" (jinjing) emerging from the "Great Abyss" (the cosmic origin) serves as the mother of all things, transcending all living beings. Ancient sages used the "golden cauldron" (alchemical vessel) to refine the elixir, though this gold is not ordinary metal but a spiritual substance capable of connecting heaven and earth.

During the alchemical process, the golden cauldron absorbs cinnabar and mercury (alchemical ingredients), generating the Qi of emptiness. This void-energy can transform into all phenomena, then return from existence to non-existence, forming a pivotal cycle of transformation. Practitioners need not fear the mutual conquest of water and fire, for when water nourishes below while fire blazes above, they paradoxically nurture each other. Water represents yin energy (the corporeal soul, po), while fire embodies yang energy (the ethereal soul, hun)—these two transform each other through "flowing pearls" (a Neidan term denoting the circulation of Jing and Qi).

The text employs the Four Symbols—Azure Dragon, White Tiger, Black Tortoise—to symbolize different cultivation stages: when metallic nature weakens and watery nature strengthens, the White Tiger transforms into the Black Tortoise (northern water deity), entering the realm of Gui-water (yin energy). The mutual generation of metal and water resembles a mother-child relationship, with yin and yang energies circulating according to temporal cycles (midnight and noon), combining strength with flexibility. The fire phases ultimately transform into earth nature (balanced state), where water and fire harmoniously coexist within the golden cauldron, forming a "four-dimensional" stable structure.

Practitioners must master the principle of "knowing whiteness yet guarding blackness" (understanding yang while preserving yin), circulating through the 365-degree celestial orbit to open the gate of life and close the door of death. When water and fire energies achieve precise balance in the cauldron, the elixir manifests its spiritual efficacy—water dissolves while fire vaporizes, their union attracting the "solar soul" (pure yang energy). The souls mutually attract: the hun (yang) stabilizes the cauldron vessel, while the po (yin) condenses the hun's energy, ultimately forming "flowing soul" (sublimated life energy) as precious as "horse teeth" (an epithet for elixir sprouts). The scripture concludes with an incantation emphasizing the gathering of souls, harmonizing wind (Qi) and clouds (Shen) through breath, causing water and fire energies to roar and refine each other within the cauldron, achieving the supreme state of soul fusion.

This scripture describes the process and principles of refining mercury (mercurial essence) in Daoist alchemy. At its core, it explains how the coordinated use of the "Hun Cauldron" (soul crucible) and "Po Cauldron" (corporeal crucible) stabilizes volatile mercury, ultimately transforming it into precious elixir.

The firing must be precisely controlled—excessive heat causes the mercury to disperse, while steady temperatures allow the elixir to take form. Here, "Hun" represents the Yang alchemical principle and "Po" the Yin principle; their mutual attraction mirrors the cyclical generation of Metal begetting Water and Water begetting Metal. The true Golden Elixir (Jindan) is not ordinary cinnabar or mercury, but a substance refined through the mutual engendering of the Five Phases (Wood, Fire, Earth, Metal, Water) within the alchemical vessel.

The process follows the rhythm of the 24 solar terms, requiring nine cycles of reversion ("nine returns") and seven stages of refinement ("seven refinements"). When complete, the elixir manifests in hues of violet-gold or ruby-jade, signaling the perfect fusion of Hun and Po. Vivid metaphors like "purple-gold crisp and ruby-jade powder" depict its ideal state.

Later passages reveal the elixir's miraculous potency: when cast skyward, it generates heaven-reversing power; when ingested, it enables "yang-reversion and bone-renewal" (rejuvenation), even ascending the practitioner into celestial realms. Imagery like the "Golden Crow" (sun) and "azure-crimson auroras" illustrates the radiant splendor within the cauldron during refinement.

This passage describes the interplay between "yang radiance" (the primordial pure yang qi) and "true fire" (heart fire) in Daoist Neidan (internal alchemy) practice, along with the profound cyclical process of cosmic kalpas.

Through breath regulation (known as "absorbing breaths"), the practitioner elevates the primordial purple splendor (primordial qi) to the solar region (upper Dantian). At this stage, the true water (kidney jing) and true fire (heart fire) within the body engage in mutual conquest and generation. When water and fire harmonize, they transform into the central earth of wu-ji (the yellow court), where illumination turns inward (concealed brightness and subdued fire), with energy latent in emptiness. This emptiness-generated qi circulates between the upper and lower Dantian, while the firing process (huohou) rises and declines according to trigram transformations (fire following the hexagrams). When yang energy reaches fullness, crystalline yang essence chases the true fire, which in turn attracts more yang energy—like sunlight focused through a yangsui (ancient burning mirror).

This light-fire generative process produces boundless radiance, as fiery qi in motion gives birth to all things. The text employs "golden chamber" as a metaphor for the body's alchemical furnace—when yang light penetrates, golden sand (embryonic form of the Golden Elixir) erupts with fiery radiance. The entire cosmos (Buddhist "three thousandfold world system") is contained within these microscopic grains of sand, each representing a kalpic cycle. Should yang light (primordial qi) be lost, the world enters kalpic periods like Longhan, Yankang, or Chiming (stages of cosmic dissolution in Daoist cosmology), where the three powers (heaven-earth-humanity) descend into chaos as earth, water, fire, and wind (the four elements) sweep through existence, returning all to primordial undifferentiation.

Yet at the extreme of darkness comes the return to origin (reversion to the source), where heaven and earth differentiate anew. This primordial qi (primal yellow upright energy) constitutes the foundation of all creation and alchemical practice. By summoning the Azure-Waisted Emissary (an inner deity) to the Hall of Lingering Light (alternative name for upper Dantian), light is refined into window dust (minute luminous particles). When the inner sun (heart-mind) undergoes qualitative transformation, water and fire naturally circulate through the twelve double-hours, with the zi-noon-mao-you periods (four key temporal nodes) corresponding to the four-nines rhythm (thirty-six firing stages) to complete the celestial cycle.

This scripture primarily discusses the application of fire phases (huohou) and the principles of Yin-Yang transformation in Daoist Neidan (internal alchemy) practice, along with the origin of the "Bright Hall" (mingtang).

Regarding the cultivation of fire phases: The hours of Wu (noon), Mao (dawn), and You (dusk) correspond to the southern and northern directions respectively. The Wu hour embodies the fire phase of Yang containing Yin. The four earthly branches Chen, Xu, Chou, and Wei (representing the four seasons when Earth energy peaks) are divided into four groups, each accumulating eight phases of fire timing—totaling thirty-two periods of water-fire harmony (the balancing of Yin and Yang). The Zi hour (midnight) embodies the fire phase of Yin containing Yang, while the hours of Yin, Shen, Si, and Hai are similarly grouped into four sets, also accumulating thirty-two fire phases.

A day is divided into one hundred ke (an ancient time unit), alternating between day and night. Daylight belongs to summer heat (Yang), while night belongs to winter cold (Yin)—their distinction follows natural Yin-Yang transformations. The division of Yin and Yang resembles an egg's shape (symbolizing Taiji), with the cycle of life and death recurring through the number seven (considered a cyclical number in Daoism). On the third day when Geng Metal energy arises, it vibrates the western direction, called "soul birth"; the Kun position in the northeast marks the decline of Yi Wood, called "soul death." Life and death perpetually intertwine—Wood's number three combines with Metal's number four to make seven (3+4=7).

The division of Yin and Yang resembles the waxing and waning moon (referring to lunar phases on the 7th and 23rd of the lunar month), merging to form the Golden Embryo (a Neidan term). Kun (Earth) combines with Qian (Heaven) to envelop the cosmos, requiring strict containment. Grasping the sun and moon (symbolizing Yin-Yang regulation) with one's hands forms the Divine Chamber (Dantian). The radiance from the Kan palace (kidneys) illuminates, filling the Divine Chamber with perfect brightness. Within the principle of "Three-Five-One" (Three-Five representing the Five Phases, One representing the Dao), Geng Metal's emergence vibrates the Dui and Qian positions, while the Kun palace envelops the Yin of Yi and Gui, with Yi Wood concealed within. The moon's phases—crescent, full, dark, and new (referring to the 7th, 15th, 1st, and 23rd lunar days)—determine fortune through the palace positions' brightness or obscurity: fullness brings auspiciousness, deficiency brings misfortune.

If the Qi of divine transformation loses its rhythm, the Golden Embryo and Divine Chamber will wax and wane like the moon (Taiyin). Skeptics need only observe the moon—yellow and white hues manifest its essence within. White represents the Hun (ethereal soul), yellow the Po (corporeal soul), mutually transforming one another. White reverts to yellow essence; black returns to yellow, their essences mingling. When the black Po is fully refined, yellow and white radiance appears. United in perfect harmony, they generate celestial Yang and earthly Yin. The White Tiger (Metal) absorbs the Azure Dragon's (Wood) light, revealing the golden elixir (Jindan) born internally. Gold and white gold divide into two eighths (symbolizing balanced Yin-Yang)—this truth has endured eternally, though rarely disclosed. Ordinary listeners disbelieve; let them witness flowers blooming and withering (symbolizing natural law). Tracing upward reveals a primordial root—the true medicine (innate Qi) that births heaven and earth. This medicine creates cosmos and humanity alike. Noble seekers must contemplate deeply—finding it grants ascent to the Jade Capital (celestial realm), mounting phoenixes and cranes to transcend the heavens.

On the "Bright Hall": It bears three names—"Shishi" in Xia dynasty, "Chongshi" in Shang, and "Mingtang" in Zhou. It served as the emperor's palace for virtuous governance and the court's hierarchical assembly. The Bright Hall venerates the sun, its gate aligned with true Yang—since antiquity, it has honored divine truth. Its name originates from the Yellow Emperor's alchemical practice at Mount Jing, where he refined golden elixirs in the Mysterious Unity Chamber. This room, near fire, generated sunlight—accumulating Yang energy to become luminous, hence "Bright Hall."

This passage elucidates the Dao of balancing Yin-Yang and the Five Phases (Wuxing) in Daoist Neidan (internal alchemy) practice, along with the calamities arising from their imbalance. The core teachings are as follows:

The celestial abode of deities (Cangjing Shenshe) corresponds to the movements of the sun and moon, requiring unimpeded circulation through the four directions (Sitong) to commune with natural forces (Lingshen, referring to water, fire, wind, and clouds). Water, belonging to the Kan trigram, is stored in the northern direction, while fire, associated with the Li trigram, resides in the south. Wind and clouds symbolize the harmonious interaction of dragon and tiger (representing east and west). The revolutions of the twenty-eight lunar mansions influence the generative and destructive cycles of the Five Phases (Wood, Fire, Earth, Metal, Water) — destructive cycles invite misfortune, while generative cycles bring blessings.

When Yin-Yang falls into disharmony, ominous signs manifest: Excessive joy triggers thunder (Yangming fire agitation), damaging Metal Qi (Jinye dissipation); unchecked anger incites warfare (Bingge), akin to flying sand, rolling stones, and comet appearances. Overly intense fire (Huohou) burns the elixir (Xuanzhu), while excessive water allows Yin to suppress Yang. Like the conflict between dragon and tiger (Yin-Yang energies), if Wood Qi becomes impaired (ailing divine dragon), it disrupts the celestial rhythms of sun and moon (Binghuo imbalance), causing Yin-Yang disorder.

The crux of Golden Elixir (Jindan) cultivation lies in mastering the "two crescents" (the Yin-Yang equilibrium of lunar phases), allowing lead and mercury (Qianhong) to transform naturally within emptiness. The true elixir (Huandan) emerges from the interplay of being and non-being — seemingly formless (Wuzhi) energies of water, wood, and metal conceal the profound mysteries of the Dao (Daocang qizhong). Form arises from formlessness; without comprehending this principle, one cannot accomplish the Golden Elixir.

This passage elucidates the subtle principles of Daoist alchemy and its correlation with astronomical calendrical patterns. It first emphasizes that the refined energies (jingling) between heaven and earth should not be carelessly disturbed, but must be refined through specific methods. Alchemical practice requires special vessels made of earthen and metallic materials (the mysterious yellow vessels of tu-jin), which undergo transformative changes when exposed to fire, generating subtle resonances. Initially faint and indistinct, these energies gradually form a misty Qi field (referring to the energy field generated during alchemical processes), resembling the bellows (tuoyue) in motion as they begin nurturing the foundation of the elixir.

The text then describes the energetic transformations during the alchemical process: the movement of the Great Yin (the moon) triggers energy conversion, where the wondrous flow of Qi coalesces into form, ultimately crystallizing into luminous elixirs. These elixirs emit crimson radiance (jinghong toupo), gradually condensing into higher states known as Jade Heaven and Crimson Heaven (referring to advanced stages of the elixir). The dancing five-colored brilliance (lihong xie) signifies the elixir's attainment of divine qualities.

The latter section details astronomical principles: the movement patterns of the solar ecliptic (the sun's orbital path), particularly highlighting the central importance of yellow occupying the middle position. It specifically describes seasonal transitions beginning from the winter solstice: at winter solstice, yang energy first emerges with the shortest daylight, thereafter increasing by one ke (an ancient time unit) every nine days until reaching spring equinox after forty-five days. The same nine-day/one-ke progression continues through spring equinox and summer solstice. After summer solstice, the pattern reverses with daylight decreasing one ke every nine days through autumn equinox, completing the full cycle of yin-yang waxing and waning. Notably, it mentions the summer solstice noon having the longest shadow (sixty ke at midday), after which daylight gradually shortens. These astronomical observations served as crucial references for ancient alchemists in determining firing times and celestial hours.

This scripture describes the principles of Yin-Yang energy circulation in Daoist Neidan (internal alchemy) practice and the process of achieving divine radiance through cultivation.

Forty-five days after the winter solstice marks the beginning of winter, followed by nine-day cycles. During each nine-day period, Yang energy diminishes by one ke (an ancient unit of time). After five such cycles totaling forty-five days, the eight solar terms (major divisions of the twenty-four solar terms) complete their cycle. The 360 days of a year are divided into 36,000 ke, corresponding to 36,000 shichen (two-hour periods). On the winter solstice, the day is shortest, with shadows moving swiftly like lightning as the sun moves ceaselessly, and the Yang energy of nature gradually withdraws and hides.

The waxing and waning of Yin and Yang energies form an endless cycle. After sixty ke, Yang energy rises again, manifesting as nine rays of glorious light. Among these nine-colored divine lights, emerald green is the most revered, symbolizing the presence of the divine. The radiant lights of the Five Thearchs (Red Emperor, Green Emperor, White Emperor, Black Emperor, and Yellow Emperor) intermingle, generating boundless divine power. Among them, yellow represents the Golden Spirit, while black symbolizes the Water essence of the north—these two energies are the most potent and enduring.

The Supreme Dao Ancestor (Taishang Dao Zu) states that this essence-energy is the purest and truest, containing the patterns of the celestial order (Tianfu). When the divine talismans circulate, they produce violet spiritual light, which transforms into the essence of the elixir. When spirit (Shen) and primordial Qi unite, they ascend as violet mist. The movement of Qi follows the celestial stems: Geng and Ren represent the mutual generation of metal and water, while Jia and Bing symbolize the fusion of fire and water. Just as two fires form flames and two woods form a forest, Yin and Yang energies are as close as siblings.

The trigrams Kan (Water), Li (Fire), Zhen (Thunder), and Dui (Lake) symbolize the pairing of male and female and the harmony of Yin and Yang. The numbers seven and eight represent Yin-Yang balance, while nine and six symbolize Qian (Heaven) and Kun (Earth) as father and mother. This relationship mirrors the human world, where fathers and sons pass down traditions through generations. The union of lead and mercury (Neidan terms for Yin and Yang energies) follows the same principle as human relationships. When Yin and Yang merge perfectly, they produce pure essence-energy. In the practitioner’s Dantian (Palace of Luminous Spirit), phenomena such as tiger roars and dragon chants emerge, the five tones and six pitches resonate in harmony, and divine light shines brilliantly in all directions.

This scripture elucidates the profound process of Daoist Neidan (internal alchemy) cultivation, employing symbolic language to reveal the natural principles of Yin-Yang mutual generation and the Five Phases' cyclical interactions.

The text begins with the governance principle of "illuminated hall and upright De (Virtue)," emphasizing harmonious ruler-minister relations, benevolent governance, and balanced civil-military affairs. This mirrors the Neidan practice of maintaining Yin-Yang equilibrium and Five Phases harmonization. During cultivation, when the body's Shen (spirit) and Qi (vital energy) become abundant, the five energies (Metal, Wood, Water, Fire, Earth) intermingle like swirling mist. Practitioners must align with nature's Qi rhythms, following the cosmic dance of Yin-Yang through day-night and seasonal cycles.

The text employs poetic imagery like "forming cinnabar in the Moon Palace" to symbolize the condensation of Jing (essence) within the body. "Horse teeth" represent the initial manifestation of the Golden Elixir, while "golden crow bones" signify solar essence. These refined substances merge with lunar radiance in the "lunar grotto" (Yin energy convergence point), creating the metal-water mutual generation state within the "illumined hall" (Dantian). As practice deepens, yellow liquid (refined Jing-Qi) emerges internally, with cauldron boiling and mercury flow (Qi circulation) eventually congealing like ice.

The dragon (heart's Shen) and tiger (kidney's Jing) pursue each other, flickering within luminous manifestations. The cinnabar's (Neidan) spiritual quality originates from divine consciousness, requiring perfect Yin-Yang attunement. The text emphasizes "three solar illuminations and three lunar movements," referencing the operational laws of dual energies. Water and fire interaction (one water, two fires) generates the Three Powers (heaven-earth-human), which then give birth to all phenomena. Mercury (original spirit) undergoes triple transformation before finally crystallizing into numinous essence (Golden Elixir).

This cultivation embodies the natural laws of Five Phases generation and restraint, mysteries inaccessible to ordinary perception. Only sincere Dao practitioners can comprehend the wondrous applications of elemental interactions. Sages observe gnomon shadows, listen to water clocks, examine the cosmic diagrams above while responding to cauldron transformations below, thus mastering heaven-earth operational patterns.

The final passage depicts visionary experiences: the spirit turtle (northern water essence) moving with fire, the black tiger (kidney's true essence) meeting the white tiger (lung's metal energy), the crimson dragon (heart's original spirit) leaping into the azure dragon's (liver's wood energy) cavern. Lead and mercury (refined Jing-Shen) unite, the Golden Elixir merges with the golden chamber (Dantian), completing the cosmic union within the radiant mystery palace.

This scripture elucidates the transformative process of mutual generation and restraint between Yin-Yang and the Five Phases (Wood, Fire, Earth, Metal, Water) in alchemical practice, along with the miraculous effects of refining the Golden Elixir (Jindan). The resonating sounds from the cauldron and tripod (alchemical vessels) symbolize the circulation of Yin and Yang energies within the furnace. Though Metal (associated with heavenly stems Geng and Xin) normally restrains Wood, under specific conditions it paradoxically fosters its growth.

When the moon reaches the Ding position (celestial stem orientation) and Metal enters Fire's domain, the flourishing Fire melts Metal, which after refinement in turn nourishes Wood's vitality. Subsequently, Fire extinguishes into Earth, Earth generates Metal, Metal produces Water, and Water regenerates Wood—thus the Five Phases engage in cyclical generation and restraint like parents bearing children. The Kun trigram (representing Earth) gives birth to the Zhen trigram (Thunder), while the Dui trigram (Lake) regenerates Kun. When the energies of Three Yang and Five Yin reach fullness, the Three Luminaries (sun, moon, stars) harmoniously revolve.

The moon waxes as it rises in the east, becoming full before beginning to wane after sixteen days as Yin energy grows. Through twenty-three or thirty-five day cycles, Metal enters Water's domain while Kun's energy disperses. Water returns northward to congeal into Metal, transforming again into Water-Fire duality. These metamorphoses follow hexagram mutations, mirroring human life's fluctuations. Within the alchemical furnace lies hidden power—like a crescent moon (Yanyue) nurturing the golden embryo (elixir precursor)—which eventually liquefies into golden fluid, first coagulating like yellow butter before fragmenting into golden granules. Their hue shifts from yellow to crimson, glowing brilliantly to form the Returned Elixir (Huandan).

At furnace opening, radiant clouds burst forth as golden sand appears powder-fine. After evenly blending and kneading these granules into millet-sized pellets, their sacrificial offering to heaven and earth renders them priceless—a single grain enabling ascension to immortality. The adept gains power to summon winds and rains, command myriad spirits, even alter seasons: turning winter scorching, summoning summer frost, making autumn bloom with spring flowers, or bringing yellow leaves in springtime. This embodies the realm where "the cosmos rests in one's palm, and all creation springs from one's body."

Mighty rivers may curdle into cream, and metal-transmutation surpasses the North Dipper's might. These are no empty words—the crux lies in comprehending the mystery of "generating being from non-being": how heaven and earth emerge from void, enabling cultivators to share the cosmos' longevity. But remember: such secrets must never be lightly revealed to mortals, lest calamity strike. Only through prudent practice and accumulated hidden virtue (Yinde, meritorious deeds done in secret) can divine protection be secured, ultimately accomplishing the immortal path.
