《還丹眾仙論》

Preface to the Fifth Chapter of "Discussions on the Golden Elixir by Various Immortals"

Compiled by Yang Zai, the Mountain Hermit Embracing Simplicity

The so-called Golden Elixir (Jindan in Daoist alchemy) originally refers to the Black Gold (wujin, an alchemical ingredient) within the Hua Pool (huachi, an alchemical term denoting either the Dantian or a specific refining vessel). Within this Hua Pool emerges Divine Water (shenshui, a technical term for specially prepared alchemical material) - a crystalline liquid that transforms into frost-white purity, known as "White Gold Yellow Sprouts" (baijin huangya, the initial product of alchemical process). When combined with the essence of Triple Yang (sanyang zhi jing, pure Yang Qi) and subjected to repeated refinement through water and fire, this substance undergoes nine transformations to become violet powder called "Purple River Chariot" (ziheche, the intermediate product).

Adding mercury to the Purple River Chariot and subjecting it to another nine transformations yields True Gold (jingong). When this True Gold merges with mercury in perfect fusion and undergoes nine final refinements, the ultimate Golden Elixir is achieved. Ingesting this elixir grants longevity beyond aging, rejuvenates the elderly, cures all ailments, transforms mortals into immortals, and confers natural immortality. However, the true understanding of lead and mercury (qianhong, fundamental alchemical ingredients) requires oral transmission from a master. The lead mentioned here isn't common black tin, nor is the mercury ordinary quicksilver - they refer specifically to Lead Essence (qianjing) and Cinnabar Mercury (zhuhong), specialized alchemical materials.

In alchemical theory: The Kan trigram (one of the Bagua) represents Lunar Lead containing the True Tiger; the Li trigram symbolizes Solar Mercury housing the True Dragon. When Dragon and Tiger unite, they naturally form the Wuji (central position in the heavenly stems). Kan water generates metal while Li fire generates wood - thus completing the Five Phases (Wood, Fire, Earth, Metal, Water). The Golden Elixir embodies this Five Phase synthesis: metal as the White Tiger, wood as the Azure Dragon, fire as the Vermilion Bird, water as the Black Tortoise, with earth unifying all four manifestations. These are not mundane metals like gold or silver.

The authentic Golden Elixir emerges from lead-mercury fusion: lead loses its fixed form in water while mercury gains fluidity in fire. From nothingness comes True Lead through water transformation and True Mercury through fire refinement. To comprehend these concepts - True Lead, True Mercury, Divine Water, Hua Pool, Azure Dragon, White Tiger, Yellow Sprouts, White Snow, River Chariot, and Divine Chamber - oral instruction from a master has always been essential.

I, a native of Xihe in Fenyang, began my Daoist practice at twenty. After thirty years of seeking, I finally encountered an enlightened master who imparted the essential formulas, allowing me to penetrate the principles of alchemical scriptures, decipher their profound language, witness creation's true workings, and comprehend the mysteries of ascending and descending energies. On the eighth day of the eleventh month during Emperor Renzong's fourth year of the Huangyou era (1052 CE), I compiled this volume "Discussions on the Golden Elixir by Various Immortals" by synthesizing essential teachings from multiple alchemical classics, offering it to fellow seekers of the Dao.

The Celestial Worthy of Primordial Beginning (the supreme deity in Daoism) states: Within the profound darkness and serene state of Wuwei (non-action) lies the root of the great Dao. This realm is formless in its primordial chaos, pure and untainted in essence, transcending the constraints of material form to attain the realm of absolute emptiness. He further explains: Before the separation of heaven and earth, there existed the pure, undifferentiated primordial Qi (vital energy). When this unified Qi divided, the clear and light energy ascended to form heaven, while the turbid and heavy energy descended to form earth. This primordial Qi circulates ceaselessly between heaven and earth. From this Qi emerged essential essences: the celestial essences manifest as the sun, moon, and stars, while the terrestrial essences manifest as lead and mercury (the two crucial substances in alchemy). Here, lead represents the essence of the moon, and mercury embodies the spirit of the sun.

The Dao Lord (a high-ranking Daoist deity) declares: The union of the sun’s spirit and the moon’s essence is the core of refining the Elixir of Return (the Daoist elixir of immortality). Obtaining Yin energy produces white cinnabar, while obtaining Yang energy yields golden cinnabar. When the golden cinnabar enters the five viscera, it spreads like wind and rain, permeating the limbs and entire body.

Laozi (venerated as the progenitor of Daoism) teaches: Waidan (external alchemy, using minerals to refine elixirs) arises from the Divine Water (a special liquid used in alchemy), while Neidan (internal alchemy, cultivating the body’s essence) emerges when the Dharma Water (the body’s vital energy) converges. He further states: Red lead (Yang alchemical material) and black lead (Yin alchemical material) form the foundation of the Great Elixir (the supreme alchemical medicine). Fusing red lead into black lead refines an elixir as pure as true gold. Red lead captures the essence, while black lead captures the marrow—their combined use yields extraordinary effects. Infusing red into black extends life, while infusing black into red leads to celestial immortality. Both methods are called the "Elixir of Return." The black material transforms its form, while the red material governs the medicinal properties. These secrets were inscribed by Laozi on the stone cliffs of Hangu Pass and Mount Liang.

Shennong (the legendary progenitor of medicine) explains: Cinnabar and mercury are the crystallized essences of the sun and moon. The solar essence is called Bright Cinnabar, while the lunar essence is called Mercury.

The Yellow Emperor’s Scripture of the Nine Cauldrons records: Lead cannot be used alone—it must be combined with other materials. Careful study reveals that lead and mercury share the same origin, generating a golden essence known as "Beautiful Golden Radiance."

The Supreme Sovereign (a high-ranking Daoist deity) states: White substances are light and floating, while golden substances are heavy and dense. They must be combined in precise proportions, tempered and harmonized through smelting, to produce the highest-grade elixir. The efficacy of an elixir balanced in hardness and softness surpasses all other methods.

Immortal Mao Jun sings: Within Yin lies Yang, and within Yang lies Yin—just as the seasons alternate and the tiger roars while the dragon chants. Azure, black, red, and white each hold their rightful positions; any disruption leads to the loss of order. Yang energy serves as the minister, while Yin energy acts as the ruler. Grasping this principle ensures the natural flourishing of the Dao. He adds: The Elixir of Return appears to contain no elixir, yet within it lies the path of return. Without lead, no elixir can be refined—the true Elixir of Return originates from lead. He further states: Powders white as snow and golden sprouts like tender shoots—without mastering the secret, one should not boast in vain. Ordinary people fail to recognize the true Yellow Sprout (an alchemical term for the essence of medicine), mistaking mere lead for golden blossoms.

The Discourse of Immortals on the Reverted Elixir presents essential teachings on Daoist alchemical practice. Here's a modern interpretation:

1. Foundational Principles of Alchemy

The "flowers" used in elixir crafting (referring to raw materials) are inanimate substances that can be transformed into immortal medicine through specific methods. The "divine chamber" (alchemical furnace) mirrors heaven and earth, where black (mysterious yellow) lead and white substances intermingle vertically. The key lies in harmonizing six elemental forces to generate substantiality from emptiness. Just as the Three Terraces and Five Peaks (symbolizing cosmic structures) transform with firing temperatures, comprehending this principle ensures success—failure leads to deviation.

2. Practical Alchemical Methods

• The Dragon-Tree Verses state: Thirty jin of "Yellow Dragon's Black Essence" (lead-mercury compound) requires slow refinement over gentle fire. The furnace base should narrow (two fen), while the top maintains ventilation. Through complete cycles, the White Tiger (lead) and Yellow Sprout (proto-elixir) transmute into "yellow silver" (preliminary elixir).
• Master Yin Ye advises: Ninefold refinement of "Golden Splendor" (elixir essence) forges the crucible. Perfecting this vessel yields ascension elixirs.
• Cultivating Yellow Sprout (elixir foundation) begins with lead refinement. Yang-phase Ren-water resists direct firing, while Yin-phase Gui-water sublimates like mist. As hens brood eggs to term, cicadas shed husks naturally.

3. Essential Formulae

• Ma Mingsheng's Golden Tiger Formula: Black lead transforms into Yellow Sprout over eighty-one days through three material metamorphoses. At Purple Sun Palace (supreme state), even gold pales in comparison.
• Golden-Blue Resolved Doubts: Mercury-gold union mirrors dragon-tiger coupling, producing the Reverted Elixir. Gold-silver fusion creates supreme treasures, though both are rare. Golden Splendor denotes Yellow Sprout.
• Hundred Questions Treatise: Metal refinement requires no matrix-material, yet quality ingredients help. Beyond Yellow Sprout, few agents control mercury. True mercury lacks impurities like pure asafoetida. Absorbing Five Phases' essence and solar qi, decade-long refinement enables metamorphosis.

4. Alchemical Mind-Techniques

The Elixir-Heart Mirror reveals: Lead holds five hues, mercury generates three blossoms (elixir phenomena)—their union forms the "River Chariot" (pivotal alchemical process). Mundane practitioners bankrupt themselves unknowingly, while adepts master ascension through these secrets. Mercury's sinking nature requires true lead's essence for balance. Without recognizing genuine lead, prolonged practice brings scant success.

(Note: Terms like "Yellow Sprout" and "River Chariot" are Daoist alchemical concepts denoting preliminary elixir forms and Yin-Yang energy cycles; "dragon-tiger" symbolizes the complementary attributes of lead-mercury materials.)

Yuanyangzi (a Daoist alchemist) explains in his commentary: To induce transformation in refined metal essence (known as "white gold" in alchemical terminology), the key lies in mastering the subtle variations of fire regulation. These techniques require oral transmission and are difficult to fully express in writing.

Wei Boyang (Eastern Han dynasty alchemist) states in Wu Xiang Lei: The essence of Golden Elixir (Jindan) refinement lies in handling the relationship between lead and mercury (fundamental alchemical materials). The essence of lead resembles plant roots—from these roots sprouts emerge, and when these sprouts mature, they can subdue mercury. Once mercury is subdued, the Golden Elixir is achieved—this is purely an internal transformation process requiring no external additives. Practitioners must never use mundane gold or silver in their alchemical work.

The Secret Record of Golden Elixir documents: Simply place nine-times refined lead essence within the divine chamber (alchemical vessel) to nurture metallic water, temporarily borrowing the power of lead's Qi. Master Hu Gangzi remarks: Other immortals never mentioned this crucial material—without it, true transformation cannot be completed. Just as nine-cycled lead essence would prove instantly fatal if ingested without proper processing.

Ge Hong emphasizes in Baopuzi: Immortals refine golden medicine for personal consumption, not worldly wealth. The silver medicine they produce is equally ingestible—this is no fraudulent deception.

The Unified Triad Treatise observes: The Golden Elixir requires multiple medicinal substances cooperating through ten thousand refinements, yet all must undergo the crucial "fire-subduing" process. Scriptures state cinnabar can refine gold while "river chariot" (lead) can refine silver—once achieved, these become true gold and silver. Mastering this method leads to immortality.

The Secret Record explains: Lead appears white externally but conceals redness within, while cinnabar appears red externally hiding whiteness within—like frost forming from water vapor, both are manifestations of heaven-earth's natural Qi. Alchemically produced gold/silver is indistinguishable from naturally occurring metals.

The Three Emissaries of Supreme Unity reveals this secret: Lead inherently contains essence without requiring auxiliary materials like the "three yellows" (sulfur, orpiment, realgar). More vital is cultivating "yellow sprouts" (alchemical intermediate product), which in turn generate new essence. This mother-child generative cycle is called the "gushing spring treasury"—a genuine transmission. While remembering the three yellows' usage, never neglect the crucial "one black" (possibly lead or mysterious essence).

Master Rihuazi poetically describes: Yellow lead subdues black lead, white mercury penetrates mysteries. The four directions each have their correspondences—like the eastern palace maiden (symbolizing mercury) following lunar cycles, ultimately attaining the immortal path. Nine refinements produce radiant elixir light, transcending time through longevity. He adds that numinous lead and mercury share ruler-minister dynamics, their proper pairing being essential for metallic refinement.

The Supreme Unity Alchemical Manual records specific methods: Using eight taels of true lead to fashion a "divine chamber" vessel. Coated with borax and heated, one adds sixteen taels of mercury—refined through water-fire interaction without additional containers. During this水火相济 process, jade-bamboo-shaped crystals of five colors will emerge.

This passage from the Huan Dan Zhong Xian Lun (Discourse of Immortals on Reverted Elixir) explains key materials and procedures in alchemical practice. Here's the essence in modern terms:

Concerning purple-crystal cinnabar (a premium grade of mercury sulfide), it manifests in twenty-four forms, but the grave-mound shaped variety is of poor quality and should be discarded in east-flowing waters.

Master Hu Gangzi states in the Shen Gong Lun (Treatise on Divine Mercury): Refine lead essence into yellow earth to form a vessel. Within this, cultivate "flying frost" to create alchemical earth—this constitutes the so-called "River Chariot" (a key alchemical medium for transporting elixir). This River Chariot serves to encapsulate other elixirs, but applying it prematurely renders it ineffective.

Immortal Yin Zhenjun explains in Wu Xiang Lei (Five Corresponding Categories): When lead undergoes "blossom extraction" (refining its quintessence), it loses its Qi; when subjected to "essence extraction," it loses its skeletal structure. Yet the "Yellow Sprout" (nascent elixir form) preserves the triad of Heaven, Earth and Humanity, maintaining the inseparability of bone and flesh.

A subsequent verse declares: The single ingredient of mercury contains no other elements—first manifesting as "black flesh" before transforming into bone. Only through this sequential transformation of flesh and bone can permanence be achieved. Like the ceaseless revolution of the River Chariot or human procreation where parental traits endure, this reveals the true nature of golden perfection. Those who fail to comprehend this principle will never attain the ultimate truth.

The Hua Chi Jing (Scripture of Blossoming Pool) states: Combining gold and silver follows fixed methods. Mastery over metallic transformations allows immediate mercury subjugation when ingredients enter the "Blossoming Pool" (alchemical vessel). What difficulty lies in completing the process within a single day? By meticulously studying the waxing and waning cycles across twelve Blossoming Pools, even the single ingredient of "dissolved brine" can control mercury—how much more effective are gold, silver, and the twelve celestial stems? Gold-vinegar, silver-vinegar and the River Chariot all subdue mercury.

The Yin Fu Jing Zhu (Commentary on the Hidden Talisman Scripture) notes: True lead contains mercury—called "tiger-mercury" or "dead mercury." Ancient immortals taught: To deactivate mercury, one must first possess "dead mercury." Thus lead-contained dead mercury forms the foundation, while cinnabar mercury constitutes "living mercury." Alchemists must recognize three simultaneous mercury states—without this knowledge, even myriad techniques cannot reveal the transcendent path. These three mercurial states are: mercury, mercury, and mercury (representing distinct transformative phases).

Immortal Yin Zhenjun clarifies in San Dan Shi Li Lun (Explanation of Three Elixirs Theory): Boiling refinement requires no complex procedures, nor does purification follow fixed methods. The crucial knowledge lies in crucible placement and fire regulation. While chaotic Qi resists differentiation, proper management through embryonic respiration and Blossoming Pool practices ensures success. Mastery over fire phases without error cultivates the embryonic respiration body.

The Can Tong Lun (Congruent Unity Treatise) states: Cinnabar undergoes five transformations—first becoming mercury, then snow, then sand, then earth, and finally lead, which is fundamentally gold.

The scripture concludes: A single substance embodies five colors; water accomplishes immortal blessings. This illustrates how simple alchemical materials, through transformative processes, produce miraculous effects.

Master Yin Zhenjun (a renowned Daoist alchemist) explains in his "Treatise on the Three Elixirs":

When cinnabar undergoes special refinement by practitioners, it manifests a crimson halo. First, the practitioner must subdue its fiery nature with yin energy to preserve its essential purity. At this stage, the cinnabar turns white and is called "White Horse Teeth." When this material is combined with the "Four Symbols of Primordial Chaos" (the four fundamental states of cosmic inception), it yields the "Non-Dual Water" (an alchemical term referring to water harmonizing yin and yang).

The alchemical process mirrors fetal development in the womb: the Qi of primordial chaos is nurtured in the "Purple Palace" (another name for the Dantian) until it forms a miraculous elixir. Just as human gestation naturally completes in ten months, mastering the Purple Palace refinement method qualifies one for immortality.

There are three temporal scales for elixir refinement in the Purple Palace: the fastest completes in one day, the moderate in one month, and the longest in one year. Specific methods include:

1. Precise fire regulation using mercury and sulfur

2. The "Golden Cauldron Method" (an alchemical apparatus) for processing lead powder over a year

The movement of Primordial Qi (fundamental life energy) follows this pattern: Wood generates Fire, which then returns to Wood. The color green represents Wood, whose Qi generates Water. When Water and Fire achieve balance, the essential Qi of Wood condenses into a substance resembling "Zengqing" (a mineral used in alchemy).

The optimal time for refining Zengqing is during the third month of spring, when yang harmony energy can be gathered in resonance with musical pitch variations (ancient cosmology held that musical tones corresponded with celestial movements). Achieving the precision of yin-yang tonal harmony in Zengqing refinement leads to the "Three Elixirs of Original Spirit" (the perfected cultivation of upper, middle, and lower Dantian).

The oral formula states: Primordial chaos is the source of the Five Phases. Zengqing gathered on Jia days (celestial stem calendar) embodies the essence of Wood. When essence and Qi circulate to form energy channels, this manifests yin containing yang. Yang Qi resembles the sun's spiritual core—father of all things. When yang transforms into white liquid that congeals like solid ice, it forms yang within yin.

The "Yang Crow Bone" (an alchemical term) generates white liquid through Qi transformation, undergoing four natural stages of metamorphosis. Common misunderstanding identifies Zengqing with the Fire phase, which is incorrect. Another interpretation suggests: mercury corresponds to bodily Qi; Qi transforms into blood; blood generates hair; hair forms skin; contours develop in three months; full formation completes in ten months; the final two months constitute the "Bathing" stage (alchemical term for gentle nurturing).

The "Lead Participation Formula" records: When lead is refined into cakes, it generates golden crystals. After nine transformations, combined with "sand-gold water" (alchemical solution) and clam powder, it yields mercurial yellow fluid (a crucial intermediate product). Authentic alchemical materials descend like celestial water, whereas common lead ore often causes errors. The fundamental principle lies in the mutual generation of water and earth.

The "Yellow Sprout Song" advises: Seekers of immortality must recognize true "Yellow Sprouts" (nascent elixir forms) by discerning genuine "lead blossoms" (essential lead). Only naturally formed true lead qualifies as alchemical material.

This scripture expounds the essential principles of alchemical practice, employing symbolic language to describe the process and rationale of inner alchemy (Neidan):

On Elixir Refinement:

Ingesting a single Golden Elixir (Jindan) enables one to ascend beyond heaven and earth, where every place becomes an immortal realm. Naturally occurring "yellow sprouts" (essence of lead) blossom into "red flowers" (essence of mercury), transforming through the mediating power of Earth (Wuji) into golden sand (the elixir). These essences are all contained within the "autumn stone" (lead-mercury compound) between the primordial darkness (Xuanhuang), yet ordinary people fail to recognize their value.

On Mercury Processing:

To stabilize mercury ("kill" its volatility), one must first neutralize its active nature. Mercury possesses self-restraining properties that grant it spiritual potency. If refined with impurities, it can never achieve true elixir status.

On Four Symbols Coordination:

The Azure Dragon (Wood), White Tiger (Metal), Vermilion Bird (Fire), and Black Tortoise (Water) each occupy their respective directions but must coordinate harmoniously. Their perpetual interdependence creates constant mutual reinforcement. The Purple River Chariot (Jindan) refined through this process enables daylight ascension.

On Five Phases (Wuxing) Circulation:

Heaven-born spiritual substances comprehend profound mysteries, circulating through the Three Dantian energy centers while radiating five-colored light. They conceal themselves in fire yet transform through earth. True fire isn't necessarily red, nor is genuine lead necessarily black. Though people prize gold and silver, few grasp their subtle principles. The "four yellows" (including realgar) and "eight minerals" ultimately lack sufficient Qi.

On Alchemical Process:

When refining with the Five Spirits (essences of the Five Phases), extraordinary phenomena appear—like blocking a flowing river with a sword. When Wood Qi (Azure Dragon) attempts to escape, Earth Qi (Yellow Hound) subdues it. As energies fuse into unity, they gradually condense into the elixir. The perfected Purple River Chariot, after removing metallic toxicity, can cure illnesses and reverse aging.

On Mental Cultivation:

Maintain mental serenity and sever desires. Merely ingesting a minuscule amount (one "knife-point measure") can summon rainbow clouds to lift one heavenward.

On Lead-Mercury Harmony:

Lead and mercury must harmonize like conjugal union. When the Purple River Chariot reaches completion, auspicious clouds and immortal cranes arrive. The coupling of Dragon (mercury) and Tiger (lead) gestates for ten months (a complete alchemical cycle) before maturing into true "lead sprouts" (elixir embryo)—the authentic secret.

On Common Misunderstandings:

The streets overflow with unrecognized "yellow sprouts"—precious materials discarded as dust. Though powerful men recognize spiritual medicines, greed obscures their vision.

Supplement by Master Yuanyang:

The Five Phases' profundity is unfathomable; Dragon (mercury) and Tiger (lead) hide within Water (Kan) and Fire (Li). Though hundreds of alchemical methods exist, the Golden Flower Crucible technique reigns supreme. Lead and mercury share common origins yet must never intermix—even sages cannot fully comprehend the Golden Elixir's mysteries.

This scripture primarily discusses the application of lead and mercury (fundamental materials in alchemy) and the principles of Yin-Yang harmony in Daoist alchemy, along with specific alchemical methods. Here's a modern interpretation:

On the fundamental principles of alchemy:

The true Dao of Yin-Yang is actually right before our eyes—there's no need to seek it afar. Ordinary people refine elixirs year after year, mistaking the blue and yellow transformations in the furnace for success. In truth, only when opening the furnace after completing the Ninefold Reversion (the highest level of refinement) can one see the medicinal flowers turn crimson. The interaction of water and fire ultimately returns to earth (referring to material transformation during alchemy), but how could ordinary people ever find the true Golden Elixir?

Master Peng's alchemical verses state:

Place black lead (alchemical material) into the Crescent Moon Furnace (a type of alchemical vessel)—by the Hour of Zi (11pm-1am), the white color will dissipate, revealing blue on the surface. After golden flowers appear below, repeatedly alternate the firing technique between east and west positions. Through continuous operation, black lead transforms into blue sand. Stir-fry vigorously over fierce fire, and soon it will become yellow flowers. When blue sand is tempered into lead powder, and yellow flowers become yellow dan (lead oxide), the world has witnessed these transformations yet remains ignorant of how to refine the Golden Elixir. Ten thousand temperings are inherently difficult—consumption requires even greater caution.

Master Yin's received verses on the Blue Elixir say:

Nüwa's five-colored stones that mended the heavens ascended to form a celestial canopy in the Great Luo Heaven. Within the azure sky, Yin energy circulates—sulfur (Yang) must pair with wood essence (Yin). The Human Emperor refined silver to attain longevity, as fire entering thunder accords with the Five Phases. The twelve-month celestial cycle operates—the Ninefold Golden Elixir's essence is ultimately the quintessence of wood. The term "Golden Elder" represents the water of the Kan trigram; when it flies into the Gen palace (northeast position), it becomes fixed. Yin and Yang take form in the east, with the entire process returning to the central earth positions (Wu-Ji). The supreme Dao of heaven and earth cannot be lightly transmitted—gold and silver are my ingredients for the Blue Elixir. To comprehend Laozi's profound mysteries is like Yin Xi receiving Nüwa's true transmission.

Supplementary Golden Elixir verses:

Though dragon and tiger (metaphors for lead and mercury) have two names, their root lies in the single primordial Qi. To learn alchemical methods, the key is using metal essence (lead) to nurture wood essence (mercury). The wondrous principle of true emptiness actually hides within lead, though not visibly. Those who discern the Yellow Sprout (initial manifestation of the elixir) can transcend the mundane; understanding the White Tiger's (lead) principle ensures longevity. Silver vessels contain three substances (likely referring to Jing-Qi-Shen), while golden embankments hold the Five Phases. The oral formula for Divine Water in the Hua Pool (saliva) is crucial—pity that worldly people remain ignorant, hence their difficulty succeeding.

Celestial Master Zhang points out:

The hard, toxic nature of mountain metals makes direct refinement into golden fluid impossible—consuming such paste-like substances would damage bone marrow. However, when metals are refined into liquid using medicinal processes, the effects become excellent. When refined to yellow-red liquid like water, ingestion enables soaring to heaven (ascension).

Tao Zhi's Three Records state:

White gold (likely true lead) transforms from northern water, altering its original form.

(Note: The text extensively uses alchemical terminology—lead and mercury, dragon and tiger all metaphorically represent Yin-Yang elements; Ninefold Reversion and Yellow Sprout describe different alchemical stages; directions and time periods reference firing techniques).

This scripture primarily elucidates the principles of Five Phases mutual generation and the mysteries of elixir formation in alchemical practice.

Regarding the refinement of the Great Elixir (Golden Elixir), the text states: During the refinement process, one must maintain continuous water flow to properly dissolve substances. As recorded in the jade texts of metal vessels: when encountering "divine water" (a technical alchemical term denoting special liquids), black and white components will separate.

The text employs the Five Phases and celestial phenomena to explain the origins of elixir components:

1. The Great White Star (Venus) embodies metal's essence, absorbing the moon's yin soul and Saturn's Qi, manifesting yellow internally. It corresponds with the Northern Chen Star (Mercury) to produce lead.

2. The Year Star (Jupiter) embodies wood's essence, absorbing the sun's yang spirit and water's vital energy. It corresponds with Mars to produce cinnabar. Since cinnabar contains wood's yin energy, it generates mercury (called the Azure Dragon).

3. The Chen Star (Mercury) absorbs Venus's Qi and combines with the moon's yin soul to produce lead. The lead generates "golden splendor" displaying five colors, known as yellow sprouts.

4. The Sparkling Deluder Star (Mars) absorbs Jupiter's Qi and the sun's yang spirit, entering earth to produce cinnabar. Fire generates earth, and earth containing yang energy produces realgar.

5. The Town Star (Saturn) absorbs Mars's energy and earth constellation's Qi, containing pure yang energy to produce realgar.

The text concludes by explaining that the five major planets mutually transmit the essence of sun and moon, rotating and generating each other, thus naturally synthesizing the elixir. These celestial energies transform through specific methods during alchemical practice (such as bellows operation and fire regulation), transitioning from form to formlessness, then regenerating form from formlessness, creating the wondrous transformations of elixir formation.

This scripture elucidates core concepts and cultivation methods in Daoist alchemy, explained in modern terms:

The sun is formally called the "Dao Father," while the moon is named the "Dao Mother." The five planets each bear symbolic titles: Venus is the White Tiger, Saturn is Gouchen (a star in the Big Dipper constellation), Mercury is the Black Tortoise, Jupiter is the Azure Dragon, and Mars is the Vermilion Bird. These five planetary energies circulate ceaselessly.

The key to alchemy lies in "Yellow Sprouts" (the initial medicinal substance produced during refinement), where lead and mercury (fundamental alchemical materials) are originally of the same source. Cultivation must follow sequential stages to ultimately forge the "Golden Flower" (an alternate name for the Golden Elixir). The Golden Flower must be refined within the Gen Cauldron (a specific alchemical furnace), with the crucial step being the subduing of Yellow Sprouts—a secret method transmitted by the Great Mysterious Perfected Being.

Master Mingdao explains the "Flower Pool" (an alchemical term denoting the body's energy convergence point): Yin and Yang mutually generate each other, with both "lead-water" (symbolizing yin energy) and "mercury-water" (symbolizing yang energy) originating from lead. Understanding these four profound principles allows one to witness the intermingling of crimson and black within the Flower Pool.

An alchemical verse states: True lead (purified energy) is extracted from crude lead and blended with cinnabar (an alchemical material) from the East. Using the Golden Flower to subdue mercury (symbolizing yang energy) resembles an eagle taming sparrows, ultimately yielding the Reverted Elixir (an advanced alchemical substance). Genuine alchemical fire (refining energy) manifests as smokeless deep purple—yet ordinary practitioners often mistake Yellow Sprouts (the primary medicinal substance) as having dual forms.

Perfected Being Mengcan remarks: Dao cultivation emphasizes penetrating the mysterious origin; after comprehending celestial mechanisms, one finds them paradoxically ordinary. The Golden Elixir not only aids transcendence but also manifests supernatural powers in the mundane world. Life is fleeting—one must grasp the principles of cosmic creation. Though practitioners seek to subdue dragons and tigers (symbolizing yin-yang energies), few prevail against time's erosion.

He further states: First refine lead and mercury into granular form (an intermediate product), with prolonged nurturing occurring within the same furnace. Without forming white liquid in the "ash pool" (an alchemical vessel), how could crimson matter transform into Yellow Sprouts? The radiant Golden Elixir is precious, while the "jade stamens" (crystalline medicinal formations) inspire even greater awe. Sealing the elixir requires returning it to the cauldron to protect its essence from yin contamination.

The Yuanjun's Elbow-Back Formulas record: The Reverted Elixir has internal and external forms, each following "Three-One" methods (an alchemical principle). The internal Three-One refers to the elixir itself, while the external Three-One denotes auxiliary materials.

Elder Changbai supplements: The "Autumn Stone" (an elixir name) refined by the Huainanzi and the "Golden Flower" forged by the Yellow Emperor—the Autumn Stone is no ordinary mineral, nor is the Golden Flower literal flora. The Golden Flower refines in autumn, while the Autumn Stone blossoms in spring. A verse clarifies: Autumn Stone is true lead; the Golden Flower is Yellow Sprouts. Yellow Sprouts cannot exist without lead—essential energy must be extracted from it. Mother and son share one origin, akin to immortal realms.

The Orthodox Hidden Armor Scripture notes: Refining these two elixirs sometimes requires vessels, sometimes not; sometimes emphasizes materials, sometimes disregards them.

This scripture compiles the insights of numerous Daoist masters on alchemical practice, primarily expounding the core techniques of Neidan (internal alchemy, the Daoist practice of refining Jing, Qi, and Shen) and the ethical requirements for practitioners.

On the Essentials of Alchemy:

1. Authentic alchemical ingredients (lead and mercury) possess specific forms—understanding this prevents confusion. Sun Simiao (the renowned Tang dynasty physician and alchemist) recorded on stone tablets that true alchemical material, "black gold" (referring to lead), is right before one's eyes, but improper collection methods will lead to failure.

2. Refining the essence of lead ore swiftly reveals the "River Chariot" (a Neidan term denoting the pathway of Qi circulation). The genuine Golden Elixir requires no ordinary lead or mercury; using incorrect materials is futile.

3. As inscribed on Huashan's stone walls: while various minerals have efficacy, "Mysterious Essence" (referring to primordial Qi) is fundamental. When Yang energy is sufficiently refined, the body's Yin-Yang balance (with "Charming Maiden" symbolizing Yin essence) naturally stabilizes.

Master Yin Zhenjun (a Daoist adept) emphasizes ethical cultivation:

1. Practitioners must be grateful for all conditions: heaven's grace, divine guidance, the master's teachings, and even the nourishment of mountains, forests, water, and soil.

2. Sincerity and virtuous intent are essential. Those who betray heaven's kindness, deceive the deities, or disregard their master's instructions will suffer organ decay even if they ingest the Golden Elixir, with calamity extending to descendants.

3. The human foundation lies in the "Dharma Body" (the eternal form attained through cultivation), rooted in the Qi of the four seasons, yet this foundation originates from the innate heart-mind. The true foundation is the "Ninefold Divine Elixir" (the highest stage of Neidan).

Lü Dongbin (one of the Eight Immortals) adds:

Cultivation requires harmonizing Yin and Yang. Though the southern direction belongs to Fire (with "Charming Maiden" representing Yin energy), one must nurture Yang energy. Methods like refining the "Jade Nectar" (saliva) and tempering the essence of the Kidney region (the Water position) have been verified by ancient immortals.

(Note: Terms like "River Chariot," "Charming Maiden," and "Mysterious Essence" are retained as they carry specific meanings in Daoist alchemy that would be lost in translation.)

The Plain Interpretation of Huan Dan Zhong Xian Lun (Discourse of Immortals on the Reverted Elixir):

The immortals who cultivate the Golden Elixir (Jindan) say: Drinking a single cup of this elixir can extend life for ten thousand years, enabling one to transcend worldly constraints and wander freely. They also state: Once one comprehends the mystery of "yellow sprouts" (the embryonic symbol of the Golden Elixir), the cyclical movement of Yin-Yang occurs naturally. Refined within the furnace-cauldron representing heaven and earth, the process resembles simmering within a cauldron where sun and moon converge. The Wood phase generates longevity mercury, while the Metal phase tempers life-prolonging lead. Those who understand this principle can immediately reverse aging and regain youth.

Master Yi Xuan remarks: True lead (primordial essence) differs completely from mundane lead, just as heaven and earth distinguish purity from turbidity. If adulterated with impurities, it becomes difficult to achieve complete Dao-body realization. The deluded descend into ghostly paths, while the awakened ascend as immortals. If asked about its form, profound mystery contains yet deeper mysteries. He further states: The "charming maiden" (alchemical mercury) resembles a beauty adorned with luminous pearls, deeply concealed within the elixir chamber. During cultivation, one may hear the tiger's roar within water (symbolizing lead) and witness the dragon's radiance within fire (manifestation of mercury). Those attaining this Dao become noble, while even those merely hearing of it prosper. The ancestral masters taught: This represents the most joyful state in cultivation.

Master Hai Chan observes: It's like comprehending the golden vessel's secret amidst turbulent ocean waves. The meeting of lead and mercury resembles the intimate reunion of mother and child, while Yin-Yang harmonization parallels the joyful gathering of ruler and minister. The eight directions circulate like fire-dragons in motion, while the four celestial creatures arrange themselves as fierce tigers descending to springs. To later cultivators he advises: Elixir refinement must employ "water-region lead" (primordial true lead). He continues: The Golden Elixir resembles white lotuses in clear water, their pistils containing purple cinnabar. Nothing in the mundane world compares, nor does any higher state exist between heaven and earth. When the golden tiger (lead) first appears, it conceals dark hues; when the fire-dragon (mercury) initially submits, it transforms into yellow sprouts. Divine illumination penetrates to return to true reality, yet none but destined individuals may glimpse this wonder.

[Essential Instructions for Well Examination]

After purifying a well for elixir preparation, absolutely avoid stirring or contaminating it. Wait until water veins stabilize, then repeatedly replace water to eliminate impurities. Expose the well water to stellar and lunar radiance, and only draw water after the liquid stabilizes and earthly qi fully dissipates. If the well bottom consists of bluish-white stone layers, this indicates yang-vein water, most suitable for elixir preparation. Should you encounter blue clay, black earth, yellow springs with red veins, or water bearing metallic astringency, these signify mixed Yin-Yang - such water cannot be used. A new well must be dug elsewhere.

[Immortal Scripture Method for Mountain Dwelling]

Those wishing to practice in mountains or select dwellings must first investigate geomancy's auspicious and inauspicious signs. On Wuji days (earth-element peak days), write the Thirty-Six Celestial Sigils of Nine Earths with yellow ink on white paper. Place this at the dwelling's center, covered with a pure basin. After three days and nights, examine: if the paper shows bluish moisture stains, this indicates subterranean remains; if white stains appear...

The Discourse of Immortals on Reverted Elixir primarily discusses the observation of omens and specific operational protocols during alchemical practices. I will explain this in two parts:

I. Interpretation of Omens

During alchemical operations, pay attention to the following color changes in the paper talismans:

• A fierce red hue indicates impending frightful changes
• Black coloration with moisture suggests hidden treasures beneath the furnace
• Yellow coloration with moisture signifies great fortune
• Purple coloration with moisture guarantees successful elixir formation

If no abnormal color changes occur, the maximum period of peace is three years—beyond this timeframe, harm is inevitable.

II. Specific Alchemical Methods

1. Furnace Construction Standards

On the Wushen day (the fifth day) within the Jiazi cycle (a ten-day celestial stem-branch period), collect pure soil from the Shen (southwest) direction on the compass. First build a three-tiered earthen platform, then construct an octagonal furnace with one gate on each side. Each gate must have an upper compartment housing the cauldrons: the water cauldron above and the medicine cauldron below. The water cauldron should have an exposed opening for water replenishment, which must be sealed after filling.

Furnace specifications:

• Total height: 2 chi 1 cun (~70cm)
• Width: 1 chi 6 cun (~53cm)
• Inner chamber diameter: 1 chi 3 cun (~43cm)
• Wall thickness: 3 cun (~10cm)
• Front fire gate: 5 cun (~16cm) high, 4 cun (~13cm) wide
• Rear vent for fire Qi emission, resembling a stove's chimney

2. Fire Regulation (six five-day phases per month)

Documents precise fire intensity modulation across monthly phases:

• Phase 1: 1 liang (tael) of fire initially, increasing to 2 liang after 2.5 days, maintained for 30 shichen (60 hours)
• Phase 2: Increase to 3 liang, then 4 liang after 2.5 days
• Phase 3: Increase to 5 liang, then 6 liang
• Phase 4: Maintain 6 liang without reduction
• Phase 5: Begin decreasing from 4 liang to 3 liang
• Phase 6: Reduce from 2 liang to 1 liang

This cycle repeats monthly. From the second month onward, increase initial fire by 1 liang monthly until reaching the ninth month's fixed 9 liang (the "Yang Nine Yin Nine" fire limit). No further increases occur between three to nine years thereafter.

Critical considerations:

• Ignition must commence on a Jiazi day
• Solar fire follows celestial progression
• Temporal fire operates inversely to mundane rhythms
• Optimal operation period: Zi (23-1h) to Wu (11-13h) hours
• Monthly fire adjustments at month's end
• Annual fire increase by 1 liang
• Mercury-ruled days require fire intensification
• Mars-ruled days demand water reduction

(Note: The term "Ju days" in the original text likely refers to planetary rulership periods)

Methods for Identifying True Lead and Mercury:

True lead (referring to the essential lead used in alchemy) should be selected from the first refinement of premium silver ore, using one jin per alchemical furnace. For mercury (quicksilver), choose large pieces of cinnabar shaped like hibiscus flower arrowheads, using half a jin each time. In alchemical terminology, lead is called the White Tiger while mercury is called the Azure Dragon - this constitutes the fundamental principle for distinguishing these substances.

Preparation of the Hua Chi (Alchemical Vessel):

When blending lead, mercury, and cinnabar in the Hua Chi vessel, they must fuse with fire and harmonize with vinegar. The ancient perfected beings (Daoist adepts) used vinegar for integration and fire for refinement. The specific method involves boiling lead-mercury-cinnabar with rice vinegar that has been clarified and stored for a thousand days - this yields optimal refining results.

Key Techniques for Subduing Lead and Mercury:

Lead can subdue cinnabar, but cannot succeed without the fusion process; cinnabar can subdue silver, but cannot transform without silver's participation; mercury can fuse with lead, but cannot combine without proper fire control; fire can refine substances, but cannot achieve harmony without vinegar's catalytic action.

Essential Alchemical Furnace Techniques:

Take lead as the earth (base material) in three portions; mercury as the marsh (liquid medium) where one portion equals three; cinnabar as the seed in two standard portions; vinegar as the plow (catalyst) in ten measured portions; fire as the tool (energy source) with half portion being the essence; and the vessel as the storehouse that must be tightly sealed for success. When cinnabar combines with lead, mercury will naturally circulate - this is the spontaneous principle of the method, requiring no forced effort. Persist in this practice for one hundred days to attain the realm of immortals.

Method for Extracting Mercury from Cinnabar:

Grind one jin of lustrous cinnabar into powder. Select bamboo sections with tight nodes from tendon bamboo, keeping three segments: bore a pellet-sized hole in the top section, and a chopstick-tip sized hole in the middle section (as mercury's passage). Place two layers of wax paper over the middle hole, add cinnabar powder, then bind the bamboo tightly with hemp cord. Steam the bamboo vessel for one day, then coat with three-tenths thickness of Liu Yi mud (a specialized alchemical sealing compound). Bury it level with the ground, compacting the surroundings to prevent qi leakage. Apply continuous heat above the vessel's mouth for one full day - when the fire's influence penetrates, mercury will flow into the lower section with minimal loss. If insufficient heat leaves mercury unextracted (evident by remaining black-purple cinnabar), continue heating until complete extraction. Typically yields fourteen liang of mercury. This method suits both red horse-tooth cinnabar and white horse-tooth cinnabar (two premium varieties).

This scripture discusses the methods of ingesting the Golden Elixir (Jindan) in Daoist alchemy and the bodily reactions that follow. The content is divided into three main sections:

First, it details the correct method for refining "Purple Numinous Cinnabar" to extract mercury. The text emphasizes that the elixir must be placed in a thin porcelain vessel sealed with yellow wax, coated with oil, and securely wrapped in alchemical silk. The vessel should then be submerged in cold spring water for fourteen days. After retrieval, it must be steamed over water for one day to dispel cold energy before being ground into powder and formed into mung bean-sized pills using mulberry bark juice or jujube pulp.

The second section outlines the protocols for ingestion: Begin with one pill daily taken at dawn with well water. After fifteen days, increase to two pills, and after thirty days to three pills—this being the maximum dosage. Before consumption, twenty-one pills must be offered in ritual to heaven, earth, and the stars, accompanied by ritual purification (Zhaijiao), fasting, and mental clarity. The pills should be ingested while facing east, either standing or seated.

Finally, the scripture meticulously describes the physiological reactions: Initial stages may bring limb weakness, heavy knees and waist, foul breath, loose teeth, blood-spitting, thirst, vomiting, diarrhea, loss of appetite, and gradual emaciation. Subsequent phases may involve eye discomfort, mental haziness, skin ulcers with pain, sensations of insects crawling, and mouth sores—all signs of the elixir expelling pathogenic factors. The text further notes possible throat pain, chest tightness, shortness of breath, or diarrhea discharging blue-yellow foul liquids or flesh clumps, indicating the elixir's attack on latent illnesses. If hunger arises, light wheat-based foods may be consumed, or the detoxifying "Elixir-Harnessing Powder" (comprising ophiopogon root, asparagus root, rehmannia, licorice, and over ten other herbs) can be taken.

Interpretation of Huan Dan Zhong Xian Lun (Discourse on the Elixir-Gathering Immortals):

Signs of the Three Corpses Spirits (the three harmful spirits believed to reside in the human body according to Daoist tradition) beginning to dissipate:

One may experience restlessness resembling madness, with mental disorientation. Possible symptoms include sudden fright, heart palpitations, or dreams of being bitten by venomous snakes/tigers/wolves, falling from cliffs, encountering enemies, or being separated from loved ones. These all indicate the imminent departure of the Three Corpses Spirits. During this phase, maintain an open-hearted disposition and restrain anger. Brew strong licorice root tea and drink one or two bowls until slight perspiration occurs—this alleviates abnormal reactions.

Manifestations after the Three Corpses Spirits leave the body:

One experiences diminished ego-attachment, carefree joy, reduced desires, and spiritual serenity. This marks the initial activation of the elixir's efficacy and divine protection.

Physical transformations following elixir ingestion:

1. Bone-renewal and skin reactions: Old ailments may resurface temporarily, with possible boils or swelling that discharge small amounts of foul-smelling blood, leaving visible scars. These phenomena demonstrate the elixir vaporizing accumulated toxins and expelling them through the skin.

2. Facial and dental changes: After a thousand days of elixir consumption, one's appearance gradually rejuvenates. Teeth may loosen and jaw tension occurs—signs of new teeth emerging. Some experience intense itching sensations penetrating to the bone marrow, with new hair growth in eyebrows and ears indicating medicinal potency reaching hair follicles. After three years, all chronic illnesses vanish completely. The skin becomes delicate, beard darkens, Qi-blood circulation improves, complexion transforms, lost teeth regenerate, hearing/vision sharpen, and bones/tendons strengthen. Upon completing the three-year cycle, marrow and Qi-blood reach full abundance—one's countenance becomes childlike. The Southern Palace (governed by the Southern Dipper deity) registers this immortal attainment, while the Northern Dipper inscribes one's name in the celestial register. All divine beings reverence such an adept, whose internal Dragon-Tiger Qi (symbolizing Yin-Yang energies) achieves perfect harmony. Internal organs become pure as gold-jade, the physical constitution transforms into an immortal body capable of communing with divine consciousness. Natural weightlessness manifests, with immunity to temperature extremes and alignment with heaven-earth longevity.

Method for removing elixir toxicity:

Formula: 1 jin each of Acanthopanax bark, Sanguisorba root, and Phyllanthus emblica; 4 liang each of saltpeter and licorice root.

Preparation: Pound ingredients into powder and sieve. Simmer with the elixir in water for seven days and nights. After extraction, soak in cold spring water for one month, then boil in cow's milk for one day. Finally, steam the bottle in a double boiler for seven days and nights. Sun-dry the result and grind into ultra-fine powder, mixing with jujube pulp to form pills.

(Note: "Southern Palace registration" refers to the Southern Dipper's jurisdiction over mortal lifespans, while "Northern Dipper delisting" indicates enrollment in the immortal registry. "Dragon-Tiger" symbolizes the harmonization of Yin-Yang energies within the body.)

This passage describes several methods for preparing medicinal elixirs:

The first method:

Roast licorice root over fire, then hold it in the mouth to slowly dissolve while swallowing the saliva. Alternatively, decoct the licorice into a broth, cool it, and drink it to counteract toxins.

The second method (collecting snow water before Spring Begins):

Before the solar term of Lichun (Spring Begins), collect clean snow water in ceramic urns or similar containers (avoid using snow from rooftops). Boil the snow water for later use.

The third method (bamboo tube decoction):

1. Take fresh bamboo tubes and scrape off the outer green layer

2. Wrap the tube opening with multiple layers of raw silk cloth

3. Place the medicinal herbs inside the tube, then position it in a pot filled with black beans (ensuring the beans don't submerge the tube opening)

4. Slowly add water for boiling. During the dog days of summer, add honeyed water inside the bamboo tube

5. Continuously replenish water to maintain the level, taking care not to tilt the tube

6. After sufficient boiling, remove and process using the "water flying" method (a Daoist purification technique involving repeated washing and sedimentation)

7. Finally, mix with jujube pulp and roll into pills the size of hemp seeds. Take two pills on an empty stomach, swallowed with saliva.

(Note: These are specific alchemical procedures from ancient times - do not attempt modern replication. The "water flying" technique refers to a traditional Daoist pharmaceutical process of repeated aqueous washing and sedimentation.)
