《諸家神品丹法》

The Inner Chapters of Baopuzi record that ancient practitioners collectively referred to the secret arts of refining gold and silver as the "Yellow and White Techniques" (a Daoist alchemical term where "yellow" signifies gold and "white" signifies silver). These methods spanned twenty-five scrolls of profoundly abstruse content. The ancients held these arts in such reverence that they avoided direct terminology, instead using coded language like "Gengxin" (the heavenly stems representing metal) to denote gold and silver.

Many dismiss these techniques as fabrications, just as they doubt the existence of immortals. In my youth, under the guidance of Masters Zheng and Zuo on Mount Lu, I successfully practiced these methods. However, the process demanded rigorous purification rituals (zhaijiao) and numerous taboos—its difficulty rivaled even the refinement of the Nine-Cycle Elixir (jiuzhuan dan).

Worldly people often mock my devotion to these "heterodox" pursuits, accusing me of forcing insight into heaven and earth's inscrutable mysteries. Yet why would I do so? To chase literary fame for posterity? My Outer Chapters of Baopuzi and other writings already fill over two hundred scrolls—more than enough to secure my legacy. Moreover, the Inner Chapters are plain records without embellishment.

Many deem me impractical, arguing that discussing mundane principles would better suit popular tastes. But I persist in documenting these arts because I have witnessed their efficacy firsthand and adhere to my masters' teachings—this is no idle speculation. Poverty, misfortunes, logistical barriers, and the scarcity of ingredients ultimately prevented me from continuing the practice.

Now, if I claim mastery of gold-refining arts while shivering in hunger, it would be like a cripple selling a cure for lameness—who would believe me? Yet truth often defies expectation, so I diligently record these methods, hoping future seekers of the Dao may discern their essence.

The transformative arts (bianhua zhi shu) of heaven and earth know no bounds. Just as the visible body can vanish from sight, or formless spirits manifest visibly—many adepts achieve such feats. Though fire and water reside in the heavens, they can be drawn using the yang-sui (ancient fire-lens) and fangzhu (ancient water-catcher). Lead, naturally white, turns vermilion when smelted into cinnabar (dansha); cinnabar, red by nature, reverts to white lead when reduced. Clouds, rain, frost, and snow are but configurations of celestial qi—yet all can be replicated through alchemical preparations.

This scripture primarily examines the phenomena of transformation in nature and humanity to demonstrate the validity of alchemical practices.

The text observes that although birds, beasts, insects, and other creatures each possess fixed forms, they may suddenly alter their original shapes, manifesting countless transformations. As the most spiritually endowed beings, humans too undergo marvelous metamorphoses—men and women changing bodies, transforming into swans, stones, tigers, apes, snakes, turtles, or mandarin ducks. Even mountains become abysses and empty valleys turn into hills. Since such grand transformations follow the natural laws of heaven and earth, why should other substances be incapable of transforming into gold and silver?

The author provides illustrative examples: Fire obtained through the yangsui (an ancient fire-making tool) and water drawn using the fangzhu (an ancient water-gathering instrument) are no different from ordinary fire and water. When snakes transform into dragons or thatch turns into grease, the results are indistinguishable from their naturally occurring counterparts. The root of these transformations lies in natural resonance—only those who deeply investigate the essence of things can comprehend these principles, and only those who trace phenomena to their origins can perceive their true nature.

The text criticizes those with limited vision who dismiss such phenomena as fabrications simply because they aren't recorded in Confucian classics like those of the Duke of Zhou or Confucius. Citing Liu Xiang’s failed attempts at gold-making as grounds to reject alchemy is likened to declaring crops unplantable after witnessing farmers suffer floods or droughts—an equally absurd conclusion.

Finally, two alchemical cases are presented: Wu Taiwen, a governor of Chengdu, once witnessed the Daoist Li Gen transmute lead and tin into silver using a small amount of elixir, though his official duties prevented personal experimentation. Cheng Wei’s wife, who mastered gold-making techniques, demonstrated the transformation of mercury into silver when her husband repeatedly failed. Yet she refused to teach the method, believing "attaining the Dao requires karmic affinity." Cheng Wei exhausted his family fortune but never obtained the secret formula.

This passage recounts several stories about the transmission of Daoist arts and alchemical practices. It first mentions a man named Chi Ta Fu, who firmly believed that Daoist methods should only be passed to suitable individuals. He was willing to teach even chance encounters with predestined seekers, but would never reveal secrets to hypocrites—even under torture. When his wife was interrogated, she went mad, ran naked, and ultimately died covered in mud.

Next is the story of Hua Lingsi, the governor of Lujiang. A learned scholar initially skeptical of Daoist arts, he encountered a Daoist who demonstrated the art of transmutation: first turning lead into silver with one medicinal substance, then transforming the silver into gold with another. The Daoist also taught him clairvoyance—after less than a hundred days of practice, he could see the stars through his roof while lying in bed at night, and even his deceased wife, Yaohua, appeared to converse with him. Hua Lingsi marveled that the wonders of the world far surpassed what Confucian classics recorded.

The text emphasizes key precautions for alchemy: one must observe purification rituals (Zhaijiao) for over a hundred days, with certain critical steps requiring oral instructions from a master. The process is best conducted in secluded mountains, away from worldly disturbances, and must never be revealed to the uninitiated. The failure of Liu Xiang’s palace alchemy is cited as proof—impure environments and human distractions lead to failure. Just as dyeing cloth must be hidden from outsiders, the art of transmutation demands even greater secrecy.

Finally, it references Master Zheng (possibly Ge Hong), who stated that true adepts (Zhenren) refine gold for immortality elixirs, not wealth. While ordinary gold and silver can be ingested, they lack the efficacy of alchemically prepared Golden Elixirs (Jindan). To those who questioned why adepts didn’t simply use worldly gold, Master Zheng explained that most Daoists were poor and thus needed to produce their own, citing the proverb: "There are no plump immortals or wealthy Daoists in this world" to illustrate the ascetic nature of cultivation.

This passage discusses the methods ancient Daoist practitioners used to refine elixirs and transform base metals into gold and silver, as well as the differences between various cultivation levels. It mentions that refining gold requires collaboration between master and disciples, yet ordinary people could hardly obtain sufficient precious metals. The true art of transformation lies in using the essence of elixirs to transmute metals—this artificially refined gold is more valuable than natural gold because it aligns with the natural Dao of heaven and earth.

The Scripture of Divine Immortals records that the essence of cinnabar can generate gold, which is why gold deposits are often found beneath cinnabar-producing mountains. Authentically transformed gold remains undiminished even after a hundred refinements, indistinguishable from naturally formed gold. In contrast, deceptive methods—such as using azurite (a copper ore) to dye iron so it resembles copper, or treating silver with egg whites to mimic gold—produce only superficial changes.

The text compares different cultivation approaches: superior practitioners ingest cinnabar-refined Golden Elixirs (Jindan) to ascend as immortals; middling practitioners extend their lifespan through consuming lingzhi mushrooms and practicing breathwork (Daoyin and Tuna); while inferior practitioners rely solely on herbal medicines to live about a thousand years. The Jade Register Records states that immortality is attainable for all, yet failure often stems from hesitation. The Bronze Pillar Scripture notes that cinnabar can be transformed into true gold, and the "River Chariot" method (lead-mercury alchemy) can swiftly produce genuine silver.

The author laments in conclusion: those who master alchemy often lack wealth to purchase materials, while the wealthy distrust these methods. Ingredients like halite and chalcanthite, worthless in peaceful times, become priceless during chaos. Many possess elixir recipes yet cannot practice them—a truly lamentable situation. Both Master Huang Shanzi and the Tortoise Shell Scripture emphasize that "my destiny lies with me, not heaven," affirming that perfected elixirs and gold-transmutation indeed enable one to live for eons. The ancients did not deceive us.

This passage elucidates key principles and common misconceptions in alchemical practice (Waidan), which can be understood through several aspects:

First, it addresses how many who show interest in alchemy often hesitate to practice it for two main reasons: the substantial financial investment required to procure medicinal ingredients, which makes people reluctant to spend money; and the impossibility of success without receiving essential oral instructions from a genuine master (Mingshi). Just as in medicine, where seemingly simple prescriptions exist, truly effective formulas are often closely guarded secrets.

The text lists a series of peculiar-sounding alchemical ingredients—such as "maidens from the rear palace," "oblique glue," "hidden dragon's liver," and "white horse's sweat"—which are actually coded names for ordinary substances. For instance, "the maiden by the river" doesn't refer to an actual woman, nor does "Lingyang Ziming" denote a real person; these are all alchemical metaphors. Laypeople might mistake terms like "dragon's gall" or "tiger's paw" for actual animal organs, interpret "broken cup" or "overturned basin" as iron or ceramic utensils, or assume "Envoy of the Hu King" or "Wild Husband" refer to real individuals. In truth, these are all symbolic names for specific medicinal materials.

The author cites the example of Liu Xiang, a renowned Han Dynasty scholar who failed in his alchemical pursuits, to illustrate that even erudite individuals cannot succeed without authentic transmission of the oral formulas. Yet, with the correct methods, even ordinary practitioners can achieve alchemical success.

Finally, a specific elixir recipe is provided: Select realgar from Wudu (a place known for its quality), which should be as vividly red as a rooster's comb and free of stone impurities. At least five catties are required, ground into powder and mixed with ox bile. This mixture is then placed in a red earthenware cauldron (a specialized alchemical vessel) with a capacity of one dou. The layering technique is crucial: first, a three-fen-thick base of halite (rock salt) and chalcanthite powder; followed by a five-fen layer of realgar powder. This alternating pattern continues until the vessel is full.

This passage describes several methods used by ancient Daoist practitioners for preparing elixirs and metallurgical transformations, primarily focusing on cinnabar processing and metal conversion techniques.

The method for preparing cinnabar water: Take one jin of cinnabar and place it in a bamboo tube, adding two liang each of natural copper sulfate (shidan) and saltpeter. Seal both ends of the tube with a mixture of lacquer and bone powder. After the sealant dries, place the medicine tube in a porcelain vat containing bitter wine and bury it three chi underground. After thirty days, it will transform into a red, bitter medicinal liquid.

The alchemical method Master Jin Lou learned from Qing Linzi involves: First prepare a tin block measuring six cun square and 1.1 cun thick. Coat the tin with a paste made of red salt and lime juice. For every ten jin of tin, use four jin of red salt. Place this in a special red clay crucible (tufu), seal it, and heat with horse dung fire for thirty days. Upon opening, the tin will turn to ash containing bean-sized metallic granules called "geng" (a metallic compound). Approximately ten jin of tin yields about twenty liang of geng. The text specifically notes that only clay crucibles from Changsha, Guiyang, Yuzhang, and Nanhai regions are suitable for this process.

The method for preparing red salt: Mix one jin each of rock salt (hanyan) and alum (yunie), place in an iron vessel, and heat over charcoal fire until completely melted before use.

The metallurgical method Master Jiao Li learned from Ji Qiuzi involves: First place two portions of alum water in an iron vessel, boil over charcoal fire, then add an appropriate amount of mercury. After stirring sixty to seventy times, pour the mixture onto the ground where it transforms into silver. This process requires supplementary materials including cinnabar water, azurite water, and realgar.

These methods reflect how ancient Daoists pursued elixirs and metal transformations through chemical experimentation. The mentioned "horse dung fire" refers to a gentle heating method, while "clay crucibles" were specially made ceramic containers. It's important to note these records primarily hold historical research value, as the described metal transformation effects require scientific verification.

These are descriptions of several ancient alchemical (Waidan) preparation methods, explained one by one:

Method for Creating Purple-Gold Powder:

Place two portions of water in a vessel and heat gently until boiling. Add silver in any desired quantity, boil six or seven times, then pour onto the ground to obtain high-quality purple gold powder. Constant stirring ensures material integration. Adding charcoal fire during boiling yields optimal results.

Method for Preparing Realgar Water:

Fill a fresh bamboo tube with one jin of realgar (a mineral medicine) and two liang of saltpeter. Seal both ends with lacquer-bone paste, then soak in vinegar and bury three chi deep in a cool, shaded place. After twenty days, the preparation is complete.

Method for Making Blue-White and Pill-Stone Waters:

The preparation methods for blue-white water and pill-stone water are identical, differing only in the type of bamboo tube used.

Child's Gold-Making Method:

Prepare two iron cylinders—a larger one (one chi two cun in diameter, one chi tall) and a smaller polished one (six cun diameter). Pulverize and sieve one jin each of red halloysite, saltpeter, mica, and hematite, along with half-jin of sulfur, four liang of azurite, and one jin of mirabilite. Mix with vinegar to form a paste, then coat the smaller cylinder's interior to a thickness of two fen. Combine one jin of mercury, half-jin of cinnabar, and half-jin of "excellent flight" (liangfei), stirring until the mercury becomes invisible. Place this mixture in the small cylinder, cover with mica, and press tightly with an iron lid. Melt lead in a furnace, pour into the larger cylinder to submerge the smaller one (leaving half-cun clearance at the top). Apply intense fire continuously for three days and nights to produce a substance called "purple powder."

To obtain gold: Melt ten jin of lead in an iron vessel for twenty days, transfer to a copper vessel, and add seven square-cun spoonfuls of purple powder. For silver: Add three spoonfuls of purple powder during the iron-vessel lead melting, heat until fused, then pour into water.

Method for Obtaining "Excellent Flight" (Liangfei):

Place ten jin of lead in an iron vessel exposed to open flame. Add three liang of mercury—the first substance that floats to the surface, collected with an iron spoon, is liangfei.

Wuchengzi's Gold-Making Method:

Create a cylindrical vessel five cun in diameter and nine cun long. Mix three jin of realgar with equal parts earthworm soil, pound into mud, and coat the interior (reducing inner diameter to three cun), leaving four cun open at the top. Add two ge of cinnabar water and dry thoroughly over horse-dung fire. Seal with a firm paulownia wood plug and copper lid, pack with yellow sand, then apply an outer seal of earthworm-soil mixture.

This passage describes the production method and miraculous effects of a medicinal elixir called "Yellow Geng" (Huang Geng). The preparation process is remarkably intricate:

First, realgar (a mineral medicine) is placed in a copper cylinder and heated over charcoal until the mouth of the cylinder glows red. This process is repeated until three jin of realgar completely melts. The molten substance is then mixed with an equal amount of yellow lead (litharge) to form a furnace of appropriate size. When used, this furnace is heated red-hot in charcoal fire, whereupon mercury and lead are added sequentially. As yellow matter gathers from the periphery toward the center, the mixture is immediately poured onto the ground to solidify into the "Yellow Geng" elixir. Legend states the furnace loses its potency after producing 3,500 jin of the substance.

This elixir boasts numerous extraordinary properties:

• Administration method: First soak in Vitex wine and red millet wine for 100 days until softened, then knead into pea-sized pills. Taking three pills daily, consuming one jin total expels parasites, cures all ailments, restores sight to the blind and hearing to the deaf, rejuvenates the elderly, and provides protection against fire, evil influences, and climatic extremes.
• After ingesting three jin, one gains the ability to walk on water, receives protection from mountain and river deities, and achieves longevity matching heaven's duration.
• Combined with other materials, it produces special effects: Boiling pills with Ailanthus blood and vermilion grass for eye application enables ghost perception; smearing with white goat blood and hanging over city gates repels dragons; applying black ox and chicken blood mixtures prevents epidemics; anointing livestock protects against tigers and leopards; coating with tiger gall and snake fat causes enemy troops to descend into chaos when thrown among them.
• Additional marvels include: Horse-blood-coated pills make wells boil and rivers flow backward when cast in water; white dog blood preparations compel temple spirits when thrown into shrines; rabbit blood mixtures summon Jade Maidens of Traveling Kitchens (Daoist celestial beings) to prepare meals; carp gall-coated pills part waters when carried underwater; violet amaranth-boiled pills sustain fasting for 100 days when held in the mouth; magnetite-processed pills worn in hair buns deflect weapons and reverse the flight of arrows.

The mentioned Six Ding and Six Ren refer to Daoist martial deities and directional spirits, possibly indicating methods for using the elixir in conjunction with these divine forces. The entire passage exemplifies Daoist alchemy's pursuit of immortality and supernatural transformations, permeated with mystical symbolism.

This scripture records several ancient alchemical techniques with miraculous effects, divided into two parts for interpretation:

The first part describes the multiple applications of a wondrous elixir: Holding it in one's mouth grants invisibility; spraying it northward extinguishes great fires; casting it northwestward during the Shen-You hours (3-7 PM) causes trees to wither the same day; when thrown while performing Yu Steps (a special Daoist walking ritual), it instantly kills wild beasts and venomous snakes. Writing characters on stone or metal with this elixir makes the marks penetrate the material permanently. It even revives the dead - administering it with water from the Month-Building day (a Daoist calendrical system) or spraying the deceased's face with elixir-laced water can resurrect recently departed souls. When mixed with fox or crane blood and applied to fingernails, it enables shapeshifting at will, though these transformations are illusory rather than substantial.

The second part details two secret alchemical methods:

The "Mysterious Perfected's Mercury-Subduing Gold Method" describes refining realgar, mercury and other substances into "purple-polished gold": Boil realgar, wild onions and bitter wine to dryness, then grind the residue and mix with mercury. Layer this mixture with alum and saltpeter in bamboo tubes, seal them, and bury underground for forty-nine days. The resulting substance, when smelted with mercury, produces genuine gold said to transmute ten times its weight in base metals.

The "Dragon-Tiger Scripture of the Golden Elixir" traces alchemy's origins: These Dragon-Tiger Great Elixirs (advanced lead-mercury compounds) originated during the Three Sovereigns and Five Emperors period, initially transmitted orally until written records began in the Five Emperors era. Notably, it asserts that even Laozi's Daode Jing and Buddhist sutras only discuss Wuwei (non-action) and realizing one's nature, while alchemy alone holds the key to transcending life and death.

This scripture expounds on the importance of cultivating the Reverted Elixir (Huandan), the supreme medicine in Daoist Neidan (internal alchemy) practice. Throughout history, many immortalized adepts guarded the secrets of this elixir closely, teaching only basic longevity techniques such as breath regulation, absorbing solar and lunar essences, Daoyin exercises, focused meditation (Shouyi), sexual cultivation arts, and the ingestion of herbal and mineral medicines. While these methods may temporarily prolong life, none can truly confer immortality.

The miraculous power of the Reverted Elixir lies in its ability to reverse aging, revive the dead, and transform decay into wonder—much like turning rubble into precious jewels. Its refinement process embodies profound mystery: First, cinnabar is purified to extract true mercury, which combines with lead to form "Yellow Sprouts" (a preliminary alchemical substance). These sprouts then revert to cinnabar, undergoing repeated cycles until finally becoming the perfected elixir.

The Reverted Elixir exists in three grades:

The supreme grade is the Ninefold Cycled Golden Liquid Langgan Great Elixir—a celestial treasure never transmitted to the mortal realm;

The middle grade is the Dragon-Tiger Great Elixir;

The inferior grade consists of mercury-based elixirs refined from eight minerals.

Since the Yellow Emperor's alchemical ascension, the Dragon-Tiger Elixir has reigned as the most potent formula. Even a minuscule dose can extend lifespan, dispel pathogenic Qi, eradicate the "Three Corpses and Nine Worms" (Daoist concepts of parasitic energies within the body), and stabilize the Jing (essence) and Qi in the Dantian (energy center). Ancient immortals strictly guarded these secrets, and surviving alchemical texts remain deliberately obscure, lacking crucial oral instructions—leaving later practitioners wandering in confusion, squandering precious time.

The author concludes by vowing to reveal these celestial secrets to sincere cultivators, enabling them to walk the path of dual cultivation of nature and life (Xingming Shuangxiu) without detours. Mention is made of the "True Dragon and True Tiger" formula (where dragon and tiger symbolize lead and mercury, representing Yin-Yang energies), though its specifics remain undisclosed.

The so-called "true dragon" actually refers to mercury extracted from cinnabar (a red mineral). It is formed when the essence of the sun (ri jing, solar essence) descends and permeates the earth, carrying with it the true Qi of heaven and earth. Daoists call this "gong" (an alternate name for mercury). The "true tiger," on the other hand, refers to silver extracted from black lead, which is transformed when the essence of the moon (yue hua, lunar essence) carries true Qi into the earth. Daoists refer to this as "qian" (lead).

Both of these treasures contain the true Qi of solar and lunar essences. Though lead appears solid, it harbors living Qi within; though mercury seems liquid, it transforms without fixed form. Among the seventy-two minerals used in alchemy, none are more precious than lead and mercury, for they can refine the "Dragon-Tiger Great Reversion Elixir" (a legendary elixir of immortality). Scriptures record that natural mercury can preserve a corpse from decay, while refined mercury can even revive the dead. These claims have been verified, yet those who remain ignorant never seek to understand the profound mysteries of the Golden Elixir (jindan) and the Great Dao.

A true Great Elixir (xian dan, elixir of immortality) possesses such wondrous efficacy. Those who encounter these alchemical secrets must have accumulated virtue through their ancestors and possess their own immortal destiny. If one obtains this method, it must be guarded strictly and never lightly revealed. To divulge it would bring calamity upon the revealer—even one’s closest kin, like father and son, must not be told. Only when meeting a like-minded companion, one who truly understands the Dao, may the oral instructions and essential techniques be transmitted.

To cultivate the Golden Elixir (Jindan), one must first select a sacred mountain or blessed land and find three like-minded Daoist companions. The site should be near sweet spring water, and an auspicious year, month, day, and hour must be chosen. Then, construct an alchemy chamber, fashion a clay furnace, and prepare the crucible. The crucible should be made of fired clay corresponding to the central Earth phase of the Five Phases (Wuxing), known as Wuji Earth. The inner container for holding the elixir must also be crafted from clay.

The crucible's size should be moderate—large enough to accommodate the inner container while allowing the fire's Qi (vital energy) to circulate freely. If the crucible is too large, the balance of water and fire will be disrupted; if too small, the fire Qi will stagnate. Careful consideration is essential. The furnace should have three tiers and six platforms, symbolizing the Three Powers (San Cai) of Heaven, Earth, and Humanity. The furnace should stand one foot two inches tall and one foot six inches wide, with a one-foot gap at the heart and walls three inches thick. A fire door, five inches high and four inches wide, should be opened at the front for adding fuel, while a chimney at the back vents the fire Qi. When lighting the fire, ensure the furnace is tightly sealed.

After setting up the furnace, erect an altar facing north for offerings. Prepare three portions of wine and fruit, along with three incense tables. First, light incense and kneel in reverence, then softly recite the prayer: "On this day, month, and year, in this place, I, [name], seek to refine the Golden Elixir for longevity. With sincere devotion, I pray that the immortals and true lords of the Great Dao (Da Dao) witness my piety and aid me in swiftly achieving the golden and silver [elixir]. May consuming it grant me eternal life, ascension to the Nine Heavens, and longevity rivaling the sun and moon." After reciting the green petition (Qingci, a Daoist prayer text), consume the offerings.

Before Heaven and Earth divided, there was only chaos. Upon separation, primordial Qi (Yuanqi) emerged, known as the "True One" (Zhen Yi). From One came Two, from Two came Three, and from Three came the myriad things. Among all beings, humans are the most spiritually endowed, standing alongside Heaven and Earth as the Three Powers. Yet human lifespans are limited—the longest-lived barely reach a century, while the short-lived fare even worse. In my youth, I studied alchemical scriptures and glimpsed their profound mysteries, coming to understand the method of the Reverted Elixir (Huandan, the Golden Elixir)...

This passage reveals the mysteries and transmission of cultivating the Golden Elixir (Jindan) path. The author recounts how after over twenty years of devoted pursuit of the Dao, he finally encountered an accomplished master who imparted the true teachings. Through this, he came to understand that "lead and mercury" (the fundamental substances of alchemy) actually represent the mutual generation of metal and water, while "fire times" (temperature control during refinement) must follow the principles of Yin-Yang transformation.

The art of the Golden Elixir traces back to the era of the Three Sovereigns and Five Emperors, when rulers first attained immortality through cultivation before abdicating their thrones to worthy successors. Over time, these secret methods gradually faded from mainstream knowledge, preserved only among reclusive mountain sages. Though countless alchemical scriptures (Danjing) have been passed down through the ages, their profound obscurity means few have truly grasped their essence. This is because the Way of the Golden Elixir embodies the supreme principles of heaven and earth—requiring alignment with seasonal cycles and seizing the pivotal opportunities of cosmic creation.

Those who wish to cultivate the Golden Elixir must comprehend celestial phenomena above and earthly patterns below, thoroughly mastering the transformations of Yin-Yang and the laws of hexagram imagery (Yaoxiang, from the Book of Changes). They must also understand breath regulation, the precise timing of fire phases, and the proper use of the cauldron and furnace (alchemical vessels). Most crucially, they must penetrate the mysteries of the "dragon and tiger" (symbolizing lead and mercury) in union and grasp the true meaning of these substances. Internally, they must cultivate virtue (De), while externally practicing boundless compassion—only by harmonizing spirit (Shen) with the alchemical process can one reach the realm of true Yang.

The author emphasizes that the Golden Elixir path requires karmic affinity across lifetimes; it cannot be mastered in mere days. Merely studying texts is insufficient—one must receive the oral transmissions and heart-mind instructions from a genuine adept. Finally, he compiled his acquired teachings into the Records of Golden Elixir Secrets and Correspondences, hoping fellow seekers of affinity might contemplate them.

Some people misunderstand the classics by confusing the meanings of lead and mercury (alchemical terms symbolizing yin and yang qi), arbitrarily speculating about yin-yang transformations and firing times (temperature control in alchemy). Practicing blindly like this is tantamount to recklessly entrusting one's fate to heaven.

The most crucial aspect of alchemy is mastering the firing times, followed by understanding the yin-yang furnace and cauldron (symbolizing the vessel and principles of alchemy). For example, when refining the Returned Elixir (a type of Golden Elixir), one must begin in the eleventh lunar month, when yang qi first emerges, adjusting the firing in five-day cycles. The transformation of yin qi starts from the Fu hexagram (one of the 64 hexagrams in the Yi Jing) and concludes at the Kun hexagram—this naturally aligns with the laws of yin and yang, ensuring neither climate nor timing goes awry. The refinement of lead and mercury has classical foundations, with firing control guided by the Zhouyi (Book of Changes). If the firing timing is incorrect, even genuine lead and mercury materials will fail to produce the elixir. It's like plants out of season—how could they bear fruit on time? Just as the sun and moon forever shine, their light unseen by the blind is not the fault of the celestial bodies, but of the alchemist acting too hastily.

Many make mistakes when refining lead and mercury: taking black lead for true lead, mistaking mercury for true mercury, or confusing lead oxide (lead yellow bloom) with the "yellow sprout" (embryonic form of the elixir). Others boil and refine salt brine, mercury, cinnabar, lead furnaces, litharge (lead monoxide), and various mineral pigments—these methods relying on the "five metals and eight minerals" (a general term for various ores) are not the true path. Yin Zhenjun once said: "Material substances with form are unfit to be companions of the elixir. Forcing their refinement and ingestion harms the body instead—those learning alchemy must be extremely cautious."

The true meanings of lead and mercury are obscured in alchemical scriptures. In truth, "lead" refers to silver—because silver is extracted from lead, pure silver is called "true lead." It is the lunar essence (yin energy's quintessence) born in response to the moon's qi. If refined into an elixir and ingested, it naturally bestows longevity. True lead must use silver—this is beyond doubt. Qingxiazi states: "The yellow sprout is not lead, yet it must be derived from lead. To recognize the yellow sprout, one cannot separate from lead's essence."

"Mercury" refers to quicksilver, extracted from cinnabar. It has form but no fixed substance (being a liquid metal), condensing by absorbing silver qi—hence called "true mercury." It is the solar true fire (yang energy's quintessence) born in response to the sun's qi. If refined into an elixir and ingested, it naturally stabilizes one's nature and life. True mercury must use quicksilver—there is no alternative. The Dragon-Tiger Essential Manual records: "Raw mercury can preserve the dead, while refined mercury can stabilize the living."

This scripture reveals the essential method for refining "Yellow Sprouts" (huangya), the foundational substance in Daoist alchemy. The most precious treasures between heaven and earth are the spiritual energies of the sun and moon, known in alchemical terms as the Dragon and Tiger. Among all substances, only lead and mercury (the two core materials in alchemy) can be used to refine the Reverted Elixir (huandan)—nothing else will suffice.

Lead possesses substantial form while mercury is formless. Lead contains yang energy within but appears yin externally, making it the foundation for alchemical work. Yellow Sprouts grow by drawing upon the true qi within lead, much like a plant sprouting from a seed. The master Qingxiazi states that lead is the mother of the sprouts, and the sprouts are its children. Once the essence of Golden Radiance (jinhua) is refined, the lead can be discarded. Mercury itself has no fixed form—it is like vapor, purely yang in nature but yin in appearance. When large quantities of mercury are heated in a cauldron until dry, it seems to have no substance. Yet when planted within lead and nourished by its essence, it transforms into tangible Yellow Sprouts—the process of generating form from formlessness.

The adept Yin Zhenjun explains that "generating substance from the insubstantial" is the principle behind the Reverted Elixir, and Yellow Sprouts are the root of refining the Great Elixir (dadan). The Taiyi Zhi records that without obtaining Yellow Sprouts, one cannot refine the highest grade of Reverted Elixir. The optimal time for refining Yellow Sprouts is the White Dew season (eighth lunar month), when the moon is golden and full—the most auspicious period for alchemy. Begin the process in the eighth month, using the Nine Cauldrons (jiuding) to extract Yellow Sprouts. By the tenth month, attention must be paid to balancing water and fire, harmonizing yin and yang, and the spiritual sprouts will naturally emerge. If water and fire are not regulated, impurities from the lead will seep in, rendering the sprouts unusable.

Eight ounces of Yellow Sprouts correspond to the waxing moon (around the eighth day of the lunar month), while eight ounces of mercury correspond to the waning moon (around the twenty-third day). Combined, they make one jin (sixteen ounces), matching the numerological significance of the 384 hexagram lines in the Yijing. During the waxing moon, regulate the fire to fully absorb the essence of lead. During the waning moon, rely on the results of the waxing phase, for Yellow Sprouts form the foundation of alchemy. If insufficient spiritual energy is absorbed, the elixir will fail to take shape.

Qingxiazi illustrates the alchemical process with three analogies: the medicine in the cauldron is like a hen incubating eggs, a fetus growing in the womb, or fruit ripening on a tree—as long as spiritual energy is abundant, it will mature naturally. However, the vessel must be tightly sealed to prevent the leakage of true qi. So long as the elixir embryo (dantai, the refining elixir) does not lose its qi, the transformation will proceed smoothly.

This passage primarily discusses selecting appropriate locations and preparing vessels prior to alchemical practice. For neidan (internal alchemy) work, one must choose sites with favorable feng shui, ideally clean and secluded places, avoiding polluted areas such as ancient temples, graves, abandoned wells, broken stoves, battlefields, or places where women have given birth. The eminent alchemist Yin Zhenjun (a renowned Daoist alchemy master) emphasized that one should never force neidan practice when unable to find a suitable location.

The most crucial facility is the "alchemy well" (danjing) - the water source for alchemical operations. Historical records show that all transcendents who achieved immortality left behind such wells, demonstrating their importance. After constructing the well, one must maintain its purity. The water must settle and be repeatedly filtered to remove impurities. The ideal source is sweet, clear spring water emerging from stone crevices - this "yang-channel water" is most suitable for alchemical work. Turbid water or water with metallic tastes should never be used, requiring practitioners to seek alternative sources.

Master Le (a Daoist perfected being) taught that after selecting the site and preparing the well, one must prepare the crucible (dingqi). The Hunyuan Jing (Scripture of Primordial Chaos) states that successful alchemy requires the fourfold coordination of kan-li (representing water and fire) as the medicinal ingredients and qian-kun (representing heaven and earth) as the vessel. The crucible shouldn't be metal but rather ceramic fired from ordinary clay, as earth gives birth to all things. Yin Zhenjun similarly advocated using simple earthenware crucibles. Regarding dimensions, ancient practitioners avoided rigid standards - the size should suit practical circumstances, being neither too large nor too small, ensuring balanced interaction of water and fire qi (vital energy).

This text meticulously records Daoist alchemical requirements for site selection, well construction, and crucible preparation, reflecting the ancients' rigorous attitude toward the alchemical environment. The detailed specifications demonstrate how traditional practitioners harmonized cosmological principles with practical craftsmanship in their sacred art.

In the practice of alchemical refinement, the arrangement of the cauldron and furnace is of utmost importance. The cauldron (the vessel for elixir-making) must be paired with a furnace, just as humans require houses and walls for dwelling. The furnace encircles the cauldron to gather the fire's Qi. Below the furnace, construct a three-tiered altar platform, with each level featuring eight gates on eight sides. Install partitions at the gates, and place the cauldron upon these partitions.

The upper part of the cauldron holds water, while the lower part contains medicinal ingredients. The cauldron's mouth must remain exposed for adding water and should be covered with a lid. The furnace dimensions follow precise measurements: two chi and one cun in height, one chi and six cun in width, with a central space of one chi and three cun squared and walls three cun thick. Open a fire gate at the front—five cun high and four cun wide—while leaving a flue at the back to vent the fire Qi, much like a stove's chimney. However, the designs left by ancient immortals vary, and alchemists must carefully deliberate on them.

When the Yellow Sprouts (the refined essence at the initial stage of elixir formation) enter the womb vessel (the intermediate container), which is then placed into the cauldron, and the cauldron is set within the furnace, this layered sealing prevents the leakage of true Qi. In regulating water and fire, one must rely on the water clock (an ancient timekeeping device) for precise control, maintaining uninterrupted operation from dawn till dusk. The timing of Yin-Yang transformations entirely depends on the water clock—even a slight deviation can disrupt the balance of water and fire. Some modern alchemists neglect the water clock, which is a grave mistake.

The true Reverted Elixir (a high-grade alchemical product) possesses miraculous efficacy: humans who ingest it attain immortality, dogs transform into dragons, and chickens become phoenixes, for it captures the creative power of heaven and earth. Without the water clock, how can one grasp the rhythms of Yin-Yang? As Master Bai Xuan wisely said: "Entering the cauldron without a water clock is like trying to refine an elixir without one—akin to a blind man discarding his cane or a deaf man clutching a zither."

When the water clock is precise, the furnace and cauldron are complete, and the Yellow Sprouts have entered the womb vessel, one need only await the initial stirring of Yang (the moment when Yang Qi first arises) to circulate the interplay of water and fire. The most challenging aspect of alchemy lies in mastering the fire times—this is the crucial secret. Those who understand the true fire times need not worry about failing to refine the Reverted Elixir. If the fire times are inaccurate, reading ten thousand volumes of alchemical scriptures will be in vain. The method of fire times was originally a secret transmission of ancient immortals, hence the claims that refinement takes three years, nine years, or even twelve years—all to prevent later generations from grasping it too easily.

References to "one year for the small Reverted Elixir, two years for the medium, and three years for the great" merely describe the stages of transformation in the elixir's refinement process, not the literal duration required.

This scripture elucidates the Daoist alchemical methods of temporal calculation and fire regulation. Ancient practitioners used the celestial stems and earthly branches as metaphors for alchemical cycles, correlating the twelve two-hour periods of a day (from Zi to Hai) with an annual cultivation process.

Several key concepts emerge:

The "Nine Returns" (jiuhuan) refers to the nine periods from Zi to Shen, symbolizing the complete cycle of Yang energy movement. The "Seven Reversions" (qifan) denotes the seven periods from Yin to Shen, representing the rising and falling phases of fire regulation. Alchemists calculated ten months as a full year to complete the process of "forming the embryonic elixir" (jietai chengyao), with the final two months dedicated to nurturing the elixir—much like a mother nourishing her newborn.

In practical application:

The cultivation begins each November with Qi nourishment and embryonic formation, formally commencing the firing process in January. Fire regulation follows the waxing and waning patterns of Yin-Yang: November corresponds to the Fu hexagram (single Yang birth), December to Lin, January to Tai, until October's Kun hexagram completes the cycle. Daily fire modulation employs two hexagrams (totaling sixty hexagrams)—Tun at dawn and Meng at dusk—maintaining this rhythm for ten months.

Qingxiazi (a renowned Tang dynasty alchemist) particularly emphasized that the true alchemical cycle spans merely one solar year. The so-called "three or nine years" tradition actually employs the metaphor of counting each month as a year—just as human gestation requires ten months, not two or three years. The text concludes by stressing the necessity of preparing the alchemical chamber in late October each year before commencing practice.

(Note: "Tuoyue" refers to ancient bellows, symbolizing respiratory techniques; "Tun," "Meng" and other terms are Yi Jing hexagram names representing distinct Yin-Yang states.)

This scripture describes the specific procedures and precautions for refining the "Returned Elixir" (Huandan, an advanced alchemical substance in Daoist Neidan practice). The alchemical process must begin at an auspicious time, starting one day before the Major Snow solar term with gentle fire to preheat the furnace. Only at the Zi hour (11pm-1am), when the first Yang energy emerges, does the formal regulation of water and fire (representing Yin and Yang energies in alchemy) commence.

The operation follows the transformations of the six Yao lines from the Yijing (Book of Changes), with each line corresponding to ten double-hours of fire regulation. Daily records must track the starting time, guided by the hexagram images of two trigrams. Each fifteen-day solar term cycle requires a two-and-a-half-day (thirty double-hour) cessation of fire called "dead Qi" (Siqi) - a critical taboo in alchemical practice.

Within the twelve months comprising twenty-four solar terms, subtracting these rest periods leaves only ten actual months for elixir refinement. This mirrors human gestation - just as a fetus requires ten months for full development, the Returned Elixir needs ten months to complete its "rebirth." Before and after each solar term, fire must cease for two-and-a-half days: before at the Mao hour (5-7am), after at the You hour (5-7pm). Following extraction, the elixir undergoes "ritual purification" (Muyu), involving three thousand counterclockwise grinding rotations.

Precision and secrecy form the core requirements. Three dedicated practitioners must coordinate timing, furnace regulation, and hexagram calculations without the slightest error. Nighttime operations require observing the Big Dipper's handle orientation and celestial bodies to determine temporal cycles. Alchemists must be purified cultivators working in triads with shared vows. Preparations involve fasting, ritual cleansing, and celestial offerings. During refinement, practitioners maintain rotating shifts for continuous incense and prayers, taking scheduled rests to prevent fatigue-induced mistakes during this prolonged process.

The Various Masters' Divine Elixir Methods scripture primarily expounds on the techniques and efficacy of refining the longevity-granting Golden Elixir (Jindan).

The supreme method for cultivating the Golden Elixir requires consuming only light vegetarian meals during two designated time periods (approximately four hours) each day, a discipline that must be strictly observed. During the alchemical process, the regulation of water and fire must be precise, and the transformations of Yin-Yang must follow natural laws. Within the cauldron, the miraculous elixir undergoes spontaneous metamorphosis: from the eleventh to the fourth lunar month (the Yang phase), the cauldron rotates leftward; from the fifth to the tenth month (the Yin phase), it rotates rightward.

When the elixir reaches its peak refinement, the practitioner must not leave the alchemical chamber but instead focus intently on listening for the "dragon's hum" emanating from the cauldron. Once the height of Yang energy passes, the elixir stabilizes, and the fire can gradually be reduced. By the tenth month, when Yang energy fully returns to the earth (represented by Kun, the Earth trigram), the Golden Elixir is complete—its color transforms to violet-red, radiating dazzling light. After nine cycles of refinement, the Qi of the Five Phases (Wood, Fire, Earth, Metal, Water) becomes fully abundant.

This Golden Elixir grants immortality to all who ingest it, from emperors to commoners, even birds and beasts. It can revive withered trees, regrow flesh on dry bones, and transmute rubble into gold—its miraculous effects are beyond measure.

While studying the Daode Jing and Huangting Jing, the author noted that these classics emphasize the cultivation principle of Wuwei (non-action), prioritizing spiritual refinement over the physical form. However, the author argues: the body is the dwelling of the spirit—without a physical form, where would the spirit reside? "Non-being" gives rise to "being," and "being" gives rise to form. Since this causal relationship exists, why not fortify the body? Practicing Wuwei may only lead to transcendence after death, whereas refining the Golden Elixir achieves an undying body in this very life. Golden Elixir techniques are tangible cultivation methods; with sincere practice, ingesting even a minuscule amount (measured in daogui, an ancient unit as fine as a knife's tip) ensures eternal preservation of the form, enrollment in the celestial registers, and ascension as an immortal—the highest attainment within the profound Daoist tradition.

The final passage details Lü Dongbin's transmitted method for refining the "Nine-Cycle Longevity Golden Elixir": Take eight taels of high-quality gold, grind it into powder, and mix it with eight taels of mercury. Pound the mixture in an iron mortar for one shichen (two hours) until it forms a sand-like golden paste. Repeatedly wash it with fresh water until the murky blue-black liquid (the turbid Yin-Qi from Wood's essence) is purged. Then wrap the paste in new white silk, forming a ball, and refine it by boiling with alum and vinegar, adding one tael of azurite (a blue-green vitriol).

This passage meticulously documents the ancient alchemical techniques for preparing "Six-One Mud" and the encapsulation process of the elixir womb in classical Waidan (external alchemy) practice.

The first step involves refining sand (alchemical material) through vinegar boiling: The sand is ground into powder, mixed with five sheng of high-quality vinegar, and boiled in a yao (a small handled pot). When the vinegar evaporates, warm vinegar must be replenished continuously for a full day and night. The fire must be kept low and steady, maintaining a gentle simmer. This process renders the sand as hard as iron, while the boiled vinegar remains unspoiled—a crucial technique for compacting the material.

Next is the Six-One Mud formula (refractory sealing clay): Take four liang of genuine earth essence (premium clay) and calcine it until red-hot in charcoal fire, then quench in vinegar. Combine this with one liang each of red halloysite, white halloysite, earthworm-processed soil, cinnabar, and gold-veined stone soil, plus one jin of sweet earth—seven ingredients in total. These are pounded into powder, mixed with brine and a small amount of paper fiber (reinforcing material), then kneaded into stiff clay. This mud must completely encase the refined sand without the slightest crack—any imperfections require immediate repair.

The encapsulated sand is called the "elixir womb" or "divine chamber," where the earth essence represents central purity while the other six materials serve auxiliary functions. This hermetic structure enables the lead and mercury (alchemical agents) to undergo wondrous transformations within.

The final encapsulation procedure: Prepare an iron container holding two sheng, filled with subdued lead essence (processed lead material). Position the elixir womb precisely at the center of the lead bed. After sealing the lid with Six-One Mud, apply an outer layer of slurry made from fine earth, paper fiber, and brine—about one cun thick—inspecting and repairing all cracks after drying.

A specially prepared iron furnace (similar to a cooking tripod), holding approximately one dou eight sheng, is then fixed with clay like an earthen pot, leaving only a fire entrance. The chamber must be fully packed with charcoal and ash for subsequent firing. This entire process emphasizes absolute hermetic sealing and operational precision, reflecting the exacting standards of ancient alchemical craftsmanship.

In the practice of alchemy, the medicinal ingredients must first be evenly placed at the center of the crucible (the alchemical vessel), ensuring they are compactly filled on all sides. After the sealing clay has thoroughly dried, select the third day before a Liujia day (an auspicious date in Daoism) to make offerings to the furnace deity with incense, candles, wine, fruits, spirit money, and paper horses (ritual offerings).

At mao shi (5-7 AM), take one jin of red-hot charcoal, break it into pieces, and spread it evenly at the bottom of the furnace. Cover it with a thin layer of warm ash, allowing just a trace of heat to permeate—this maintains a constant temperature in the furnace, much like a womb nurturing the elixir. Repeat the same process at you shi (5-7 PM), ensuring the fire is carefully regulated throughout all twelve double-hours of the day and night. After forty-nine days of continuous refinement, the "Mother-Child Gold" (a preliminary elixir) is formed, also known as the "Water-Wood-Fire Elixir Seed." This marks the first transformation of the "Returned Elixir" (a high-level alchemical product), referred to as the "Dragon-Tiger Supreme Treasure."

Here, the principle of the Five Phases' mutual conquest is applied: Metal conquering Wood causes mercury to condense into granules; Wood conquering Earth prevents the Six-One Clay (a refractory mixture of six minerals) from contaminating the elixir; Earth conquering Water is crucial to the alchemical process; and Water conquering Fire prevents mercury from evaporating. Only through the dynamic interplay of the Five Phases' generation and conquest can the elixir take form.

After the first transformation is complete, allow the furnace to cool before opening it. Grind the elixir powder finely, then add eight liang of the essence of Water and Wood (extracts from specific medicinal herbs). Following the previous method, pound, wash, and boil the mixture, resealing the furnace with Six-One Clay. Refine it for another forty-nine days to produce the "Divine Elixir." By the fourth transformation, the powder will have turned into fine granules, at which point lead containers are no longer necessary.

For the final stage, switch to a small iron box, filling it with the Four Divine Elixir powder (leaving two-tenths of space). Take eight liang of the finest cinnabar (vermilion) from one jin of high-quality ore, layering it alternately with eight liang of elixir powder: first spread the powder, then arrange the cinnabar like lotus petals, cover with more powder, and repeat for three layers. Only through this meticulous layering can the highest-grade elixir be perfected.

This passage provides a detailed account of the preparation method for an elixir called "Sacred Golden Sprouts" (圣金黄芽), representing a practical record of Daoist Waidan (external alchemy) techniques involving mineral-based longevity elixirs.

The process begins with ingredient preparation: mixing five parts of elixir material with four parts of cinnabar, specifically using forty taels of elixir material combined with twelve taels of cinnabar. These materials are layered into a sealed alchemical vessel (合子), with each layer firmly compacted. The vessel opening is sealed with Six-One Mud (六一泥, a specialized Daoist sealing compound typically composed of seven ingredients), then wrapped with an outer layer of salt-paper mud approximately one inch thick, left to dry.

The sealed vessel is placed in the alchemical furnace, positioned precisely at the center of the furnace ashes without tilting. The furnace mouth is similarly sealed with salt mud until completely dry. Following the First Transformation Hand Technique (a specific fire-control method), the firing process begins and continues for seven times seven days (49 days). Upon completion, opening the furnace reveals purple crystalline formations—the "Sacred Golden Sprouts," also called "Transcendent Quartz That Sheds Mortal Form" (脱凡胎圣石英).

Next, powdered Four Divine Elixirs are melted into liquid in a qi furnace and cast into golden egg-sized vessels. Two taels of fresh cinnabar are ground with eight taels of the previously obtained "Sacred Golden Sprouts," then placed into the golden vessel for sealing. The same Six-One Mud sealing process is repeated with one-inch thickness, dried thoroughly before returning to the furnace.

This stage requires more refined fire control: On an auspicious Six Jia Prime Day (六甲元首日, an important Daoist date), at mao hour (5-7 AM), heat evenly with one jin of crushed charcoal fire, maintaining gentle heat under a thin ash layer. Additional one-jin fires are added at wu hour (11 AM-1 PM), you hour (5-7 PM), and zi hour (11 PM-1 AM), with only gentle smoldering required during other periods. After another 49 days, the "Beautiful Golden Blossoms" (美金花) is obtained.

The process repeats similarly: adding two taels of fresh cinnabar, grinding, sealing, and refining for 49 days yields "Numinous Golden Frost" (灵金霜); another two-tael cinnabar addition with identical refining produces the final "Soul-Returning Sacred Golden Liquid" (反魂圣金液). The entire procedure demands strict adherence to timing, fire control, and sealing protocols, exemplifying the Daoist alchemical pursuit of meticulous precision.

This passage details the ancient alchemical method for refining "Cinnabar Elixir." First, take two taels of cinnabar and grind it into fine powder, placing it in a specially crafted alchemical vessel (hezi). Heat it gradually over fire. Choose an auspicious day and open the vessel precisely at noon, allowing direct sunlight to shine upon the cinnabar. Repeat this calcination process nine times.

Every two taels of raw material can yield thirty elixir pellets. These pellets must first be offered to heaven and earth, mountain and river spirits, dragon deities, and the sages of the Three Realms before use. For the specific procedure: take four taels of mercury and one sheng of purified water, add one pellet, and place them in a clean iron cauldron. Cover and heat over charcoal until the water fully evaporates and the mercury transforms into superior red alchemical stone.

Next, melt one jin of mixed metals—silver, copper, iron, and tin—into liquid in a furnace. Add one pellet and stir thoroughly before pouring the mixture into molds to cast ingots, which also yield superior alchemical stone. For material transformation (using elixirs to alter substance properties), the "fire toxin" must first be removed. For oral ingestion, the same applies—neutralize the fire toxin by placing the elixir in a special vessel (hezi) to dissipate its "yin toxin," then bury it three chi to one zhang underground or suspend it in a well. Finally, expose it to sunlight to achieve perfection.

The terms "fire toxin" and "yin toxin" refer to harmful components in the elixir, which ancient practitioners believed required specialized purification. The entire refining process meticulously observes timing, vessels, and post-processing—reflecting Daoist alchemy's exacting standards for detail.

The method for refining the Yellow Sprout Elixir is as follows:

First, take five taels of pure mountain-stream silver (naturally refined silver ore) and hammer it into round cakes. Repeatedly forge these cakes a thousand times to achieve maximum density—this prevents mercury infiltration. Place the prepared silver cakes into ceramic cylinders (ji tong), adding three taels of mercury (liquid quicksilver). The silver cakes should be positioned approximately two inches above the mercury pool, ensuring stable placement.

Seal the cylinder completely with Six-One Clay (a specialized Daoist alchemical sealing compound), then invert a water bottle over the cylinder's mouth. Place the apparatus upside-down and maintain constant heating with three taels of charcoal fire for seven days. Upon opening the furnace, you'll observe countless needle-like white crystals growing on both the mercury and silver surfaces—this constitutes the first transformation of Yellow Sprout.

Add another three taels of mercury and continue the heating process for seven more days. The crystals will now appear malt-colored. With each subsequent addition of three taels of mercury over seven-day intervals, the crystals deepen to golden-yellow. Repeat this process through seven cycles totaling twenty-one days, consuming twenty-one taels of mercury in total. The final purple-golden crystals obtained are called the "Mother of Reverted Elixir."

The remaining mercury in the cylinder will transform into vermilion, known as "Child Clinging to Mother" or "Solitary Cinnabar." This cinnabar can be steamed with milk, ground into powder, and mixed with jujube pulp to form pills. Taking three pills daily on an empty stomach with wine strengthens kidney essence (Jing), calms the spirit (Shen), stabilizes the corporeal soul (Po), and effectively treats wind-cold disorders.

Approximately twelve taels of Yellow Sprout crystals will form on the silver cakes, while three to four taels of unconverted mercury at the base—having "absorbed sufficient Qi"—retain their original state for separate medicinal use. The mercury-crystal amalgam constitutes the "Elixir Mother," symbolizing the union of solar and lunar essences: cinnabar representing the solar soul (Ri Hun) and Yellow Sprout embodying the lunar soul (Yue Po). As the alchemical verse states: "The sage grasps creation's profound mechanism, cradling sun and moon within the alchemical furnace."

This passage meticulously documents an ancient alchemical procedure detailing how to refine elixirs using cinnabar and other materials. The process begins with preparing five taels of premium-grade cinnabar (a red mineral), which is soaked in three liters of high-quality vinegar within an iron cauldron. The vessel should be wrapped in cloth and suspended while boiling continuously for seven days and nights, maintaining consistent heat and replenishing evaporated vinegar. After boiling, the cinnabar is removed, cleansed, wrapped in gold foil, coated with ink, and gently dried over low heat.

Next, a five-tael golden vessel is crafted, its interior coated first with a mixture of powdered ink and egg white, then with a mud-like paste made from vinegar-mixed minerals: azurite, realgar, red ochre, chalcanthite, and alum. The processed cinnabar is placed at the center of this vessel, surrounded by "Yellow Sprouts" (an alchemical term referring to a specific powdered ingredient), and sealed tightly—symbolizing a mother nurturing an embryo.

Subsequently, a mixture of green salt and niter is melted into liquid, cooled, and ground into powder for use with a silver container. The golden vessel containing the cinnabar is placed inside this silver container, surrounded by the salt-niter mixture, sealed with "Six-One Mud" (a refractory material), and dried over gentle heat. Finally, the entire apparatus is buried in an earthen furnace, covered with ash, and fired for eighty-one days under precisely controlled temperatures to complete the elixir. Before unsealing the furnace, incense must be burned and prayers offered to avoid disturbing the elixir’s "embryonic Qi."

Throughout the procedure, strict attention is paid to fire regulation, material ratios, and sealing techniques, reflecting the ancient alchemists’ obsessive pursuit of precision. These operations blend practical chemical processes with distinct Daoist ritual concepts, particularly the symbolic framing of the elixir as a living entity requiring ceremonial care.

This scripture primarily discusses two alchemical methods: cinnabar refinement and realgar refinement, along with precautions for ingesting elixirs.

Regarding cinnabar refinement: Take one portion of cinnabar and heat it gently in an iron cauldron until it becomes glossy like oil, then immediately remove it. Place mercury in a specialized alchemical crucible (ganguo), sprinkle the powdered cinnabar over the mercury, and the mercury will instantly transform into silver. Alternatively, place the cinnabar powder in a small bamboo tube and roast it in warm ashes over time to produce slightly yellowish silver. However, elixirs produced this way cannot be ingested directly—the cinnabar must be refined again with fire to remove black impurities, ensuring the elixir retains its potency.

Regarding realgar refinement: Take five taels of pure, high-quality realgar (the arrowhead-shaped variety), wrap it in gold foil coated with ink, then mix it with cinnabar. Place this mixture in an ash pool and nurture it with four taels of fire for twenty-one days. During this period, cover it with "yellow sprouts" (a technical alchemical term referring to specific medicinal ingredients) and seal it properly according to ritual. After the prescribed time, transfer it to a shallow furnace and smelt it with five catties of strong fire until it glows red-hot. Once cooled, open it to find the realgar transformed into purple-gold. Grind one portion of this realgar into fine powder, mix it with one tael of mercury in a small cauldron, and refine it with three taels of fire—it will quickly turn into purple-gold. This elixir can be used to transmute silver, copper, and other metals with extraordinary effects.

Method for ingesting elixirs: Take five taels of refined cinnabar, choose an auspicious day to grind it into powder, and boil it with jujube pulp to form pills. Each tael of cinnabar should yield one thousand small pills. Begin ingestion on a Jiazi day (first day of the sixty-day cycle), abstaining from meat and strictly avoiding sexual activity during the regimen. Before taking the elixir, one must first cultivate oneself for three years, accumulate virtuous deeds (yinde), pray to heaven and earth, and vow to perform good works. Each morning, face east, swallow saliva twenty-four times, then take three pills.

Before grinding the cinnabar, it must first be boiled for a full day and night with two taels each of emblic myrobalan (yuganzi) and fangji root (hanfangji), plus a handful of sliced sweet bamboo. Afterward, place it in a fine silk bag and suspend it in well water for seven days. Then mix it with milk, steam, and boil it further to completely remove fire toxins before forming pills. Elixirs refined this way can transmute mercury into treasure with just one tael.

It must be noted that these alchemical and ingestion methods require strict adherence to procedures—the slightest deviation may compromise efficacy or even pose dangers.

This passage describes the specific methods of two Daoist alchemical practices and the miraculous effects of their elixirs.

The first elixir is taken exclusively during spring, beginning on the Jiazi day (first day of the 60-day cycle). One consumes three pills daily for sixty consecutive days, totaling 180 pills. Consistent use can eliminate all ailments with remarkable efficacy. For those seeking to achieve "bigu" (grain avoidance), drinking a small amount of cold water each morning suffices. Its potency is demonstrated by placing a single pill on raw meat during midsummer—after a month, the meat remains fresh with vibrant color instead of rotting. If it can preserve dead flesh, naturally it extends human lifespan.

The second elixir uses processed realgar (known as "fu huo xionghuang"). Formed into date-paste pills, one pill taken daily with wine on an empty stomach can permanently cure all wind-cold disorders. Alternatively, the realgar powder can be placed in a cauldron, pierced with copper chopsticks to create vents, then heated gently with mercury to produce the radiant "Purple Golden River Chariot" (a Daoist term denoting precious alchemical transmutation). The "River Chariot" metaphor signifies its transcendent power—as rivers ferry people and chariots carry cargo. Realgar is called "Golden Millet" while cinnabar is termed "Silver Millet."

The refinement process involves multiple stages: First, create "Yellow Sprout Head" (an alchemical base called "Bubbling Spring"). Mix ten taels of Yellow Sprout with ten taels of mercury, grind into sandy texture, and place in a ceramic vessel warmed continuously with three taels of fire, with no time limit. When needed, extract portions for use while replenishing mercury—this method is called the "Path of True Yang." For a "Solitary Elixir," merely one tael of Bubbling Spring can catalyze a whole jin (catty) of medicine.

Preparation requires one jin each of alum salt and mercury, ground together to remove black impurities. Before adding Bubbling Spring, wash the mercury thoroughly with warm water. Crucially, maintain a two-finger gap between the vessel's base and medicine, with constant three-tael fire day and night. Optimal results come from thick-walled lidded ceramic vessels without cracks or pinholes.

Lastly, the "Longevity Zhenren's Plain Cinnabar Formula" prescribes: four taels of solid cinnabar, half-jin of green salt, and one tael of sal ammoniac, each ground separately. These materials require special preparation to activate their potency.

This passage describes the three-step alchemical process for refining "naosha" (a mineral primarily composed of ammonium chloride) in ancient Daoist practice.

First Step: Prepare a container by alternately layering three levels of stone-green salt (mineral salt) and naosha. Cover the vessel with a tile and construct a brick furnace around it, topped with four inches of ash. Apply gentle heat (four liang of fire) for seven days. After cooling, remove the contents. Seal the container's seams with red halloysite (a type of red clay) and "six-one mud" (a mixture of six parts clay to one part salt), then place it in an ash pit. Heat with three jin of fire until glowing red. Once cooled, extract the naosha, which will have turned gray, completing the first refinement.

Second Step: Grind one liang of naosha with half a jin of green salt into powder, mix with water to form a paste, and combine with the previously refined naosha. Without sealing, place directly in the ash pit under gentle heat (three liang of fire) for seven days, maintaining consistent temperature by adding fuel. After cooling, purple naosha is obtained, marking the second refinement.

Third Step: Grind the purple naosha into powder, mix with a small amount of green salt, and wrap in thick paper to form pellets. Coat with ink and air-dry. Place in a container under three liang of fire for three days, then apply intense heat (five jin of fire) until glowing red. The resulting snow-white naosha pellets complete the third refinement.

Final Preparation: Soak the refined naosha in cow's milk, place in a bamboo tube suspended in a well for seven days. After drying, grind into powder and mix with jujube paste to form mung bean-sized pills. Beginning on a Jia-Chen day, take the pills after fasting and incense offerings: one pill on the first day, increasing daily to seven pills by the seventh day, then decreasing back to one, repeating this cycle for sixty days.

This scripture records a miraculous elixir called "Bone-Transforming Snow-Retaining Pill" (Huan Gu Liu Xing Jiang Xue Dan) and its preparation method, with primary effects of rejuvenation, curing stubborn illnesses, and metal transmutation.

The effects of consuming this elixir are remarkably potent: within one year the body becomes light and agile, within three years one's appearance becomes as youthful as a child, with movements swift as a galloping horse. Long-term consumption leads to immortality, with even lost teeth regenerating. When combined with breath regulation (Yunqi) practices, it can transform the practitioner into an immortal. For metal transmutation (turning base metals into precious substances), it can be used directly without removing fire toxins.

Master Meng Yaofu personally testified: after suffering from kidney wind-itch and hemorrhoids for over twenty years, he was completely cured within one month of taking this elixir. After one hundred days, all Three Corpses Worms (three harmful parasites believed in Daoism to reside in the human body) were expelled from his system. His complexion became rosy, teeth and hair regrew, and his appearance became as youthful as a maiden—the marvelous effects defy complete description. For metal transmutation, a single pill could immediately transform three taels of mercury into treasure.

The alchemical preparation method is as follows:

First, take four taels of high-quality Chenjin cinnabar and boil it in a silver vessel with hundred-flower honey for seven days and nights. After extraction, mix it with ten taels of pine-lichen powder and premium honey to form a moist, fragrant paste. Line the bottom of a crucible (hezi) with this mixture, arranging the processed cinnabar like lotus blossoms, then cover with the remaining half of the mixture. Compact firmly and seal with Six-One Mud (a special sealing clay). After drying, place in an ash pool (insulation device) and warm with four taels of fire intensity for three fu periods (approximately 36 hours). After cooling, remove and wash, wrapping each piece in gold leaf.

Next, take half a catty of stone-yellow (a mineral substance) and grind into fine powder. Lay half at the bottom of a silver crucible and compact firmly. Place the processed cinnabar inside, then cover with the remaining stone-yellow powder and compact again. Seal the crucible opening with red halloysite mixed with vinegar. Place this in a large cauldron, using golden mica powder as an outer seal. Warm in the ash pool with one catty of fire intensity for twenty-one days. After cooling, remove to reveal golden elixir pellets.

Administration method: Place the elixir in a silk pouch and suspend in well water (about one foot below the surface) overnight. Remove, grind into powder, and simmer with Polygonatum juice in a silver vessel to form a paste. Shape into mung bean-sized pills. Take one pill daily on an empty stomach with "well-flower water" (the first drawn well water at dawn).

For metal transmutation: Without removing fire toxins, place one pill with three taels of mercury in a dipper, cover with a cup lid, and seal the edges with four layers of wet paper. Warm in the ash pool to produce treasure. For making gold, add one tael each of realgar and "Buddha-head blue" (mineral pigment), grind with fire-processed cinnabar, and seal in the aforementioned outer container for refinement.

Method of Nurturing Fire in a Sealed Ash Pool:

Place the materials into an airtight ash pool and refine them with a fire weighing one jin (Chinese pound) for twenty-one days. Then, apply heat equivalent to one cheng (an ancient unit of measurement) until the mixture cools. Upon extraction, it will appear in a violet-gold hue. If silverware comes into contact with the aura of this elixir, it will transform into a yellow substance. Using this elixir to transmute mercury yields the finest gold. This method must be strictly safeguarded.

Method for Refining the Chixue Liuzhu Dan (Red Snow Flowing Pearl Elixir):

Select one jin of pure, translucent realgar (a mineral medicine), crush and sieve it, then mix thoroughly with bitter wine (vinegar). After moistening for two days, allow it to dry. Repeat this process of mixing with wine and drying ten times. Next, blend it with powdered white salt and seal it under a layer of salt. After letting it sit for a full day and night, dry it over a gentle flame, gradually increasing the heat—but never too fiercely. After another day and night, switch to intense fire, maintaining consistent heat in the lower crucible from dawn till dusk without the slightest reduction. Continue this for three days and three nights, then cease the fire and let it cool for a full day and night before opening the furnace.

Collect the refined substance from the upper crucible and grind it again, while the residue from the lower crucible is crushed and mixed back into the elixir, moistened with cooked rice grains. Arrange the fire as before—balancing wenhuo (gentle fire) and wuhuo (intense fire)—and refine it once more. When complete, the elixir will take on a vivid red hue, forming pendant pearl-like or web-like radiance, dazzlingly bright. Witnesses will be involuntarily awestruck.

This elixir can save those in critical condition: for sudden illnesses, near-death states, or those who have already stopped breathing, grind the elixir finely and take an amount equivalent to three or four sesame seeds, mixed with egg yolk and administered orally. After ingestion, lift the patient’s head, and recovery will soon follow. Minor ailments are cured upon ingestion—its miraculous effects defy full description. Sadly, few understand how to refine or use it to transmute gold.

Method for Transforming Bidan Sha (Green Cinnabar) into Golden Grains:

This formula treats all feng disorders (wind-induced ailments in traditional Chinese medicine), extends life, enhances beauty, cures countless diseases, and can also transmute treasures. Combine yellow lead, white clay, and powdered tile with salt and vinegar to form a hard paste, shaping it into wax-ball molds. Ensure the clay balls are seamless, then dry them in the shade before carving a small hole and burning away the wax mold.

Grind high-quality, lustrous cinnabar into fine powder, roll it into a tube with stiff paper, and pour it into the clay ball. Seal the opening with earthworm mud and let it dry. Fashion a special iron ring to embed the elixir ball securely within the alchemical cauldron, ensuring space remains above and around it. Pour in a solution of lead and saltpeter until the liquid level sits about two inches below the cauldron’s rim.

This passage describes specific operational procedures in ancient Daoist alchemy, focusing on two distinct elixir preparation methods. I'll explain both parts in modern terms:

The first part details the preparation of "Golden Millet Elixir":

Begin by applying gentle heat continuously, ensuring the temperature never drops too low, until the lead completely melts. This process lasts 120 days. Then intensify the fire, remove the refined substance and calcine it on the ground. After cooling, bluish-purple spiral-shaped crystals will form—remove any black impurities. Divide the qualified product into two portions, storing one portion in a sealed green bamboo tube. Next, steam the elixir with milk five times, changing to fresh milk every three steamings. The used milk skin can treat skin pigmentation. Finally, bury the elixir in an earthen pit for three days, then grind it into powder and form millet-sized pills using millet rice. Dosage: one pill for 40-year-olds, two for 50-year-olds, three for 60-year-olds—never exceed this amount. Traditionally believed to cure various wind disorders, prolong life, and enhance complexion.

The second part explains "Transformed Gold Powder" production:

Take 10 taels of high-quality gold and 50 taels of mercury, placing them in a porcelain jar. Heat until the gold turns red, then add the mercury while stirring with a willow stick until fully dissolved. Incorporate 3 catties of salt flowers and grind with the gold amalgam. Spread this mixture evenly in a large pot, cover with a basin, and seal with clay. Apply low heat to evaporate the mercury completely. After full evaporation, rinse with water to remove salt residues, then sun-dry to obtain gold powder.

Final medicinal combination:

Combine 8 taels of cockscomb-red realgar, 8 taels of flaky orpiment, 4 taels of mineral salt (rong salt), 10 taels of gold powder, and 5 taels of Golden Millet Elixir—grinding all five ingredients into powder. Transfer to a new alchemical cauldron whose interior has been evenly coated with ink mixed with rice vinegar. Heat the powder with alternating moderate and gentle flames until liquefaction occurs. Add 4 taels of niter powder to fill the vessel completely, then seal the opening with wheat paste and paper. After thorough drying, the preparation is ready for subsequent refining processes.

This scripture details three specific Daoist alchemical methods and their effects.

The first is the "Lead Pouring Method": Pour molten lead into the alchemical cauldron to a depth of about two inches, then begin refining with fire during the Zi hour (11 PM to 1 AM). For the first six days, add one liang (approx. 37 grams) of lead daily, stopping after sixty days. Once cooled, the cauldron is chiseled open to reveal a purple-gold elixir. A single fen (approx. 0.3 grams) of this substance can transmute one jin (approx. 500 grams) of mercury into gold. However, the text emphasizes that this is not a technique ordinary people can master—it requires secret transmission from an immortal.

The second method, "Gilding Technique" (a metal surface treatment), involves grinding green vitriol, alum, salt, and saltpeter into powder, then forming a trough with refined clay. A metal hairpin is dipped in water, coated with the medicinal powder, placed in the trough, and fired. After immersion in water to cool, the process is repeated five times to produce a high-quality gilded surface.

The third, the "Great Void Numinous Cinnabar Elixir," is cited from the Dongxuan Collection and records Ge Hong’s (the Immortal Lord Ge) discourse on alchemy. The text states that the Primordial Lord (Yuanjun), teacher of the Supreme Lord Lao (Laojun), transmitted this divine elixir capable of harmonizing Yin-Yang and commanding wind and rain. Upon ingestion, superior practitioners may attain celestial office, middling ones may dwell on Mount Kunlun (the sacred mountain of immortals), and even lesser adepts achieve longevity. Ge Hong warns that this Golden Elixir method must not be taught to foolish non-believers, only to sincere seekers of the Dao. Quoting the Yellow Emperor’s Scripture of the Nine Tripod Divine Elixirs, he notes that the Yellow Emperor ascended to immortality by consuming this elixir. Ordinary breathing exercises and herbal remedies merely prolong life or cure illness, whereas the divine elixir enables one to share the lifespan of heaven and earth, riding dragons to celestial ascent. Finally, Master Yi Xuan reminds that such supreme Daoist methods must be transmitted only to the virtuous and worthy.

(Note: The "fen" mentioned is an ancient weight unit, approximately 0.3 grams; the "Zi hour" refers to 11 PM–1 AM in traditional timekeeping; "Kunlun" in Daoism signifies the sacred mountain abode of immortals.)

This scripture primarily discusses the transmission principles of alchemical practice and the miraculous effects of elixirs. It first emphasizes that the secrets of alchemy must never be casually revealed: if the recipient is unworthy, even mountains of gold and silver should not tempt one to divulge a single word. Those without the karmic foundation for immortality should not be privy to these teachings, for if they reach the ears of non-believers, not only will they slander the elixir, but the alchemical process itself will fail. However, when encountering those with true immortal potential and sincere devotion to cultivation, the perfected elixir can elevate their entire family to transcendence.

The text then critiques worldly ignorance: ordinary people persistently distrust elixirs, clinging instead to herbal remedies. Yet how can plants that rot in the earth grant eternal life when consumed? Cinnabar (mercury sulfide), by contrast, is an indestructible substance—refined and ingested properly, it naturally extends life. The masses chase wealth and indulge desires like moths to flame, hastening their own demise, unlike cultivators who, though physically in the mundane world, maintain transcendent minds, strictly disciplining themselves and steadfastly preserving their devotion to the Dao (the Way).

Finally, it cites Sun Simiao (the Immortal Sun)'s Danjing (Classic of Elixirs), listing alchemical materials: the Five Metals (cinnabar, mercury, realgar, orpiment, sulfur) and the Eight Minerals (azurite, malachite, chalcanthite, arsenic, sal ammoniac, white salt, alum, saltpeter). Special mention is made that cinnabar, orpiment, and others are "sentient substances" (materials with unique spiritual properties), while differently named substances like Sengxi Huang and Shiting Zhi share identical essences. Certain materials, when exposed to flame, can transform silver to crimson or sublimate mercury into precious elixirs. Remarkable interactions occur between these substances—for instance, the Five Metals lose potency when encountering mercury, while the Eight Minerals become inert when meeting saltpeter.

This scripture primarily describes the refining methods and efficacies of two types of elixirs: cinnabar elixir and realgar elixir.

Regarding the refining of cinnabar elixir: One must select eight taels of genuine high-quality cinnabar and place it in a smooth new porcelain vessel, sealing the edges with damp soil to prevent Qi leakage. Add eight taels of mercury and the powdered form of five seahorses (a medicinal ingredient), mixing them thoroughly. Then, take semi-dry, semi-fresh red aconite shoots (a type of plant), burn them to ashes, and collect the drippings from the ashes in an earthen jar. Combine these materials in a porcelain vessel lined with raw iron frost, first heating them with a gentle flame before transitioning to a strong fire until they melt into a liquid, forming white cinnabar. Following the methods recorded in the alchemical scriptures, precisely measure the proportions according to Yin-Yang and seasonal nodes, then nurture it like a hen incubating eggs for 120 days. Finally, grind it into fine powder and shape it into millet-sized pills using pinellia juice. Consuming one pill extends life by 300 years, while ten pills extend it by 3,000 years. This elixir is called the "Divine Talisman White Snow Elixir" and can transform blood into milk. If guided by a master and combined with cultivation, one may attain immortality within three years. This elixir can also transmute gold and silver, but it must not be casually transmitted.

Regarding the refining of realgar elixir: Select purple-red, cockscomb-shaped realgar from Mount Wudu, grinding it into fine powder. Combine it with green vitriol, purple golden dragon sprout frost, and pickled vegetable shoots (also called red aconite). The specific refining method is similar to that of the cinnabar elixir, requiring strict adherence to Yin-Yang principles and seasonal timings.

This passage records several mineral processing methods from ancient Daoist alchemy (Waidan), primarily describing how to treat minerals with specific firing techniques to achieve the miraculous effect of "transmuting" metals into treasures. Here are the detailed procedures:

Orpiment (an orange-yellow mineral) processing:

Select high-quality orpiment from Mount Wudu, grind it into fine powder. Combine with green vitriol (ferrous sulfate) and motherwort ash juice, then decoct into a frost-like paste. Place the mixture in a new porcelain jar, layering it from bottom to top. Begin with gentle fire (slow heating), gradually increasing to strong fire until thick smoke dissipates, transforming it into liquid. This liquid can transmute mountain silver (natural silver ore) into treasure.

Sulfur processing:

Choose sweet sulfur, Sengxi sulfur, or stone pavilion fat (different varieties of sulfur), combine with green vitriol and red violet ash juice to make frost. Similarly contained in a porcelain jar, use alternating gentle and strong fire techniques. The resulting liquid can also transmute silver into treasure.

White-top yellow (likely a mercury-containing mineral):

Select red powdered mineral from Shangdang Mountain, combine with cinnabar, red violet ash, purple golden dragon sprouts, and skullcap ash juice for decoction. The processing method resembles the above. This liquid can not only transmute raw iron and copper but also subdue mercury (stabilizing its properties).

Azurite processing:

Take high-quality bluish-green azurite from Mount Tai's summit, grind and process with saltpeter (potassium nitrate). The resulting liquid can transmute black silver (likely impure silver) into treasure.

Malachite (another copper-containing mineral):

Also sourced from Mount Tai, appearing bluish-yellow and crystal-clear like quartz. Though the text doesn't detail its processing method, context suggests similar techniques to other minerals.

All methods emphasize using new porcelain vessels and alternating "gentle and strong fire" heating techniques, observing smoke changes to determine firing stages. The so-called "transmutation into treasure" likely represents ancient alchemists' exaggerated descriptions of mineral alloying or surface treatment effects.

This passage documents several mineral processing methods from ancient Daoist alchemy, belonging to the operational procedures of Waidan (external alchemy - the technique of pursuing longevity or metal transmutation through refining mineral medicines). Let me explain them one by one:

Regarding the refinement of saltpeter (potassium nitrate):

Grind the raw material into fine powder, add ashes from burned dragon's tooth grass, then decoct with the ash solution to form a frost-like substance. Spread this medicinal frost at the bottom of a new porcelain vat, cover it with another layer of medicine, and apply alternating Wenhuo (gentle fire) and Wuhuo (intense fire) heating. When the smoke dissipates completely to form a liquid, it can be used to transmute copper and iron into treasures.

Processing of chalcanthite (natural copper sulfate):

Originating from Puzhou, it appears glassy and transparent. Similarly ground into powder and decocted with saltpeter or dragon's tooth grass ash solution. Layered placement in new porcelain vats with controlled firing produces a liquid said to transmute Korean copper into supreme treasures.

Application of arsenic trioxide:

Select high-quality yellowish-white arsenic trioxide from Xinzhou, grind it and decoct with saltpeter or motherwort ash solution. The resulting medicinal liquid can transmute aurichalcite (brass ore) into silver and facilitate other material transformations.

Refinement of sal ammoniac (ammonium chloride):

Choose well-crystallized transparent sal ammoniac, decoct with oyster shell powder or dragon's tooth grass ash solution. The resulting liquid can remove blue-black tarnish from silverware.

Special treatment of salt:

Select naturally crystallized hard salt, decoct with antelope horn powder or dragon's tooth grass ash solution, then add motherwort powder. This refined product is said to treat eye diseases and stomach ailments while removing red tarnish from silverware.

Refinement of alum:

Process with five types of dragon's tooth grass ashes to produce a liquid that removes various colored tarnishes from silverware.

Treatment of mirabilite (Glauber's salt): Likely involves similar decoction methods with other herbal ash solutions for specific purposes.

These methods reflect ancient alchemists' exploration of mineral purification and transformation. The "Wenhuo and Wuhuo" refers to temperature control techniques alternating between gentle and intense fires, while "transmutation" denotes the concept of inducing material property changes through small amounts of medicinal agents. Note that these operations involve toxic substances and should not be replicated in modern times.

This scripture primarily describes ancient Daoist methods for refining elixirs using cinnabar and other minerals. Cinnabar (a red mineral primarily composed of mercury sulfide) was a crucial material in elixir preparation, and the text details four processing techniques.

The first method involves grinding high-quality cinnabar into fine powder, mixing it with medicinal herbs like kudzu root powder and phoenix tail dragon bud grass, then calcining the mixture with saltpeter to produce ash. This is then decocted into a frost-like substance. A new porcelain jar is used—first layered with medicinal powder, then the cinnabar, and covered with another layer of powder. Gentle heat is applied initially, followed by intense firing until smoke appears, which removes the black oxide layer from silverware.

The scripture explains that the Five Metals (gold, silver, copper, iron, tin) and Eight Minerals (cinnabar, realgar, etc.) correspond to celestial phenomena like the Five Planets, Five Sacred Mountains, Five Phases (Wuxing), and the five human organs. Proper refinement could produce life-extending elixirs and even transform base metals into gold or silver.

The second method, recorded by Ge Xianweng (a renowned Daoist alchemist), involves wrapping lump cinnabar in sheep's belly herb, drying it in sunlight, then grinding it into powder. Half the powder is placed in a porcelain container, followed by the cinnabar lumps and the remaining powder. After sealing, the mixture undergoes charcoal-fired calcination.

The third method describes silver extraction from cinnabar: alum, saltpeter, golden wings, and cinnabar are ground together and added to semi-melted borax, then boiled into powder. The cinnabar lumps are moistened in the mouth, coated with this powder, wrapped in silver foil, and sealed for calcination. Subsequent immersion in the Hua Chi (alchemical solution) yields silver.

The fourth technique combines cinnabar with herbs like maiden grass, kansui root, caper spurge, and lettuce for calcination. The container is layered with herb powder, cinnabar, and more powder before undergoing alternating gentle and fierce heat (Wenwu Huo) for a full day and night.

These methods demonstrate ancient alchemists' mineral processing techniques through calcination and chemical combination, aiming to produce longevity elixirs or metal transmutation. Modern readers should note these processes involve toxic substances like mercury and must never be attempted without proper expertise.

This scripture records several ancient methods for refining cinnabar (mercury sulfide), belonging to the Waidan (external alchemy) tradition of Daoist alchemy. Here are the key contents:

The first method involves combined refining with gold and silver: Take five taels of silver powder, five taels of premium cinnabar, and eight gold foil sheets. In a Ding kiln porcelain box, first lay four gold foil sheets, then add one qian of silver powder, place the cinnabar in the center, and alternate layers of silver powder and cinnabar until full. Seal tightly with lead powder and oyster shell powder. After drying, nourish with four taels of fire heat for fourteen days.

The second method, herbal refinement: Use tender sprouts of herbs like Euphorbia humifusa, Phytolacca, Euphorbia pekinensis, peony, Sagittaria, and purslane, crushed in equal amounts into a paste to encase the cinnabar. After drying, smelt with two to three catties of charcoal fire until liquefied.

A simplified third method: Use purslane (five-direction herb) with roots removed. Place three taels of cinnabar in a porcelain box, layering herbs first, then cinnabar, and covering with more herbs before sealing and smelting.

The fourth alum method: Combine one tael cinnabar with one tael white alum. First melt half the alum in a pot, add cinnabar, then cover with remaining alum. Smelt until glowing red.

An advanced fifth method: Use half-catty premium cinnabar with yellow alum, chalcanthite, realgar, and sal ammoniac (half tael each). Grind into powder, mix with rice vinegar into paste, and simmer gently in porcelain for over ten days. Form into firmiana seed-sized pills—one pill refined with one tael mercury under four taels of fire briefly yields treasure.

The ultimate refinement: Take one tael premium cinnabar (dice-sized), wrap in double gold foil inside a porcelain box. Fill bottom and top with nine-times-refined green salt powder, then seal with oyster shell powder. Nourish with one tael of fire from Chen hour (7-9 AM) to noon (11 AM-1 PM), then smelt under three catties of fire. The resulting cinnabar, made into sesame-sized pills with honey, is said to prolong life.

These methods reflect ancient alchemists' techniques of modifying cinnabar's properties through herbal combinations and fire control. Note: Cinnabar (mercury sulfide) is toxic—these historical methods should not be attempted today.

When wrapping elixirs in gold or silver foil and nurturing them with gentle heat for twenty-one days, those wrapped in gold foil will transform into precious gold, while those in silver foil will become true silver after the fire is properly cultivated.

Regarding the method for refining cinnabar through nine cycles: Take five taels of high-grade cinnabar and gather moss from the shaded side of an ancient wall, drying it before roughly grinding it into powder. Grind the cinnabar into fine powder and place it in an oil-proof hezi (an alchemical vessel). Layer the moss powder at the bottom and top, then seal the vessel with a mixture of earthworm excrement and salt powder kneaded into a mud-like consistency, about a finger’s width thick. Once the seal has dried, place the vessel on a brick and heat it with one jin of fire until it glows red. After cooling, remove it—the cinnabar will have solidified into a purplish-red mass, which is then ground again into powder. Repeat the firing process, and with each cycle, the color will deepen until it reaches a mirror-like, luminous purplish-red state that reflects one’s image. After nine such refinements, it can be ingested to prolong life. This is the method for producing jiuzhuan zhushakui (nine-times refined cinnabar essence).

Master Ding’s crucible method for refining cinnabar: Take five taels of high-grade cinnabar, ground into powder, one tael of powdered salt from Jiezhou, and two taels of powdered soil from the eastern gate of Fengxiang (Qin land). Separately, shape a crucible mold from clay, smoothing it into the form of a ganguo (alchemical crucible). Crush the stems and leaves of purple-stemmed lettuce to extract their juice, mix it with the salt and Qin soil powder, and knead it into a firm but pliable mud. Coat the crucible mold with a layer about five fen thick. If the structure is not sturdy enough, add paper pulp, knead again, and reshape. After removing the inner mold, dry the crucible thoroughly over low heat. Fill it with the cinnabar, then tightly seal the opening with a bundle of purple lettuce stems to prevent leakage, leaving half the space empty. Secure the bundle with string, place the crucible on a brick with a hollowed-out depression for stability, and heat it with strong fire until it glows red and smokeless. Once cooled, remove it—the cinnabar will now appear amber-colored, translucent, and mirror-like, suitable for ingestion to extend life. To produce an even higher-grade kuiyao (refined medicinal essence), repeat the firing process three to five times; each cycle will enhance its luster and density, with effects too profound to fully describe. This method can successfully refine various mineral medicines, though the sanhuang (orpiment, realgar, and sulfur) are particularly challenging. Typically, at least two jin of fire is required for the refining process.

This scripture records several ancient Daoist methods for refining cinnabar (mercury sulfide mineral), belonging to practical records of Waidan (external alchemy) – the pursuit of longevity through refining mineral-based medicines. Below are the specific techniques:

The first method, "Yellow-Stone Subdued Cinnabar Technique": Take four taels of cinnabar and one catty of orpiment (an arsenic-containing mineral), grind into fine powder and fill a sand or ceramic container halfway, compacting firmly. Insert a wooden mold in the center, pack orpiment powder around it, then remove the mold. Coat moistened cinnabar with borax and place it in the orpiment-filled container. After sealing and air-drying, bury it in a two-foot deep pit, covering with dry horse manure for fourteen days of controlled firing, constantly replenishing manure to maintain heat. Finally, apply three catties of intense fire until complete reaction occurs. The cooled peach-blossom colored product can then be used freely.

The second "Fire-Subdued Cinnabar Method": Mix lump cinnabar with purple-skinned garlic paste, spread one finger's thickness in a garlic-coated crucible. Cover with wolfberry leaves, then alternate layers of cinnabar-garlic mixture, topping with wolfberry leaves and tile fragments. Seal with halloysite (mineral adhesive) and air-dry. Place in an ash bed for twenty-four hours of alternating gentle and fierce fire, then apply ten catties of intense heat. After cooling, remove the granules, reheat until glowing red, and quench in brine until color transformation completes. If insufficiently purified, reseal and refine again with five catties of fire.

The third "Fire-Subdued White Cinnabar Method" is particularly unique: Boil Sichuan pepper for juice, then pound with silver foil and mercury into paste, filtering through gauze to form cakes sized according to the cinnabar lumps. Hold cinnabar in the mouth while chewing seven cloves, then remove and sandwich between mercury-paste cakes. Layer powdered cinnamon, aconite, roof pine and other herbs at the container's base before placing the cinnabar cakes inside. For oral consumption, add yellow lead (lead oxide). This method activates medicinal properties through oral saliva, embodying the alchemical principle of "nourishing medicine through human essence."

These techniques reflect ancient alchemists' exploration of mineral reactions, where "fire-subduing" refers to specific processes reducing mineral toxicity. Crucially, these formulas containing mercury and lead are hazardous – modern replication is strictly inadvisable.

The text describes several methods for refining cinnabar (a crucial ingredient in Daoist alchemy). The first method involves: laying a coin-thick layer of sand at the container's base, covering it with a coin-thick layer of yellow lead (litharge), then sealing the container mouth with red halloysite powder mixed with vinegar and reinforced with salt clay. Heating with half a cheng (measurement) of charcoal fire produces white cinnabar—this method bypasses the need for natural cinnabar ore.

The second boiling method for refining cinnabar: Take equal parts (one liang each) of Douji grass, five-leaf sorrel, and lump cinnabar, wrap them in a silk pouch, and soak halfway in rice vinegar. Place in an iron vessel with half a jin of rice vinegar, two sheng of water, and two liang of hibiscus leaves and branches. Simmer gently for a full day and night. After completion, dry the contents and retain only the cinnabar, discarding the other herbs.

The third refining method: Melt three liang of cinnabar in a crucible, simmering slowly until liquefied. Once boiling, splash it onto the ground to cool and collect. Then melt the cinnabar again in a gan guo (small alchemical crucible) until fluid, pouring it into a bran trough to obtain a silver-like substance.

Zhang Zihou recorded two methods for the "Treasure Elixir" technique. The first boiling method: Coarsely grind two liang each of dock root, Didingyou grass, Didan grass, and motherwort, then combine with 1.5 dou of river water and eight liang of pure, flawless "Bright Chensha" (high-grade cinnabar) in a suspended silver or stone vessel. Maintain a "fish-eye bubble" simmer, replenishing water as needed. After boiling, rinse with river water.

The second calcination method and fire control: Grind two liang each of Songluo moss, burnet, spiderflower, and Yindijue fern into powder, mixing with raw honey until fragrantly moist. Layer one-third as a base, place cinnabar pellets (lotus-seed-sized) atop, separated by herb powder, repeating until full. Seal the container mouth with red halloysite mixed with vinegar, then coat the entire vessel with liuyi ni (Daoist alchemical sealing clay) one finger-width thick. Air-dry to ensure no cracks. Finally, cover with three finger-widths of vinegar-mixed straw ash. Ignite five jin of charcoal from the top, adding another five jin when half-burned, repeating until completion.

These methods emphasize slow fire control, layered herb placement, and strict sealing—reflecting ancient alchemy's meticulous demands for temperature regulation and craftsmanship.

This passage details the concrete operational methods used by ancient Daoist practitioners in refining elixirs and transmuting metals, belonging to the practical records of Waidan (external alchemy) – the art of pursuing longevity through material refinement.

Regarding the treatment of cinnabar (vermilion, primarily composed of mercury sulfide): Place the cinnabar in a clean basin and cover it overnight, then remove it the next day. Prepare another clean sandbox and seal its opening with red halloysite (a type of red clay). Place it inside a small earthenware jar, supported by a tripod iron stand. Surround it with ash from spirit money, covering the box to a thickness of four fingers. At the hours of Zi (11 PM–1 AM) and Wu (11 AM–1 PM) each day, add four taels of red-hot charcoal. After nurturing it with gentle heat for fourteen days, apply intense fire until it glows red-hot to obtain the true "subdued fire" (a stabilized elixir processed through controlled heating). For ingestion, grind it into fine powder, mix it with pinellia rhizome juice to form pills the size of phoenix tree seeds, and take them with warm water on an empty stomach.

If the goal is to transmute metals or create a "matrix" (a foundational material for alchemy), it must be boiled three times with fresh ingredients: Each time, follow the aforementioned method of adding fire. For transmutation, mix it with mulberry paper tree juice to form pills—each tael of cinnabar makes ten pills, and each pill can transmute one tael of copper into "treasure." When preparing the "matrix," grind three qian of silver and seven qian of mercury into a sandy texture, divide it into ten portions, and layer them alternately with eight taels of coarsely processed cinnabar powder, ensuring the bottom and top layers are cinnabar. The nurturing method and heating intensity are the same as the initial cinnabar refinement: the first cycle lasts twenty-one days, with each subsequent cycle decreasing by one day until, at peak fire intensity, only one day and night are needed to form the "longevity matrix" (a reusable alchemical base).

Later, the text records the secret method of Master Xuanzhen (a Daoist name): Heat half-tael coins until red-hot, quench them in vinegar, then dip them in sulfur powder while still hot and spread them in a box. Cover and seal them with more sulfur powder. After drying, nurture them with four taels of fire for three days, then grind them finely after heating and cooling. This processed material is then used to treat cinnabar, which is said to yield higher-quality cinnabar in greater quantities.

Finally, another method for subduing cinnabar with fire: Seal cinnabar in a bamboo tube, heat it intensely until red-hot, then let it cool. Another formula is given: two taels of arsenic trioxide, half a tael of calomel (mercury chloride), one tael of gypsum, one tael of alum, and one fen of saltpeter, ground into powder and stored in a small bottle. Wrap it in black paper before placing it in a larger bottle, surrounded by lime for preservation.

These methods involve high-temperature chemical reactions. Ancient practitioners believed that through specific procedures, substances could undergo qualitative transformations, acquiring miraculous properties. From a modern perspective, they entail complex reactions involving mercury, sulfur, copper, and other elements, making them hazardous in practice.

This passage describes the specific procedures of the "Licorice Chamber Cinnabar Method" from ancient alchemical practice. It details a process for refining cinnabar (mercury sulfide) through particular techniques.

First, prepare eight taels of compact licorice root ground into fine powder, along with two and a half taels of cinnabar similarly powdered. In a porcelain container, begin by laying down a base layer of licorice powder about three fen thick. Alternate layers of cinnabar powder and licorice powder until all the cinnabar is used, finishing with a three-to-five-fen-thick licorice topping.

Seal the porcelain container firmly with paper clay, then secure it with iron wire until the entire vessel is completely enclosed like a sphere. Dig a wide pit in the ground, lining it with crushed fire material (likely charcoal fragments), followed by a layer of rice husks. Place fifteen jin (approximately 18 lbs) of burning charcoal atop this, heating until glowing red before extinguishing and removing. The inner container must never directly contact flames.

After repeating this sealing method, subject the vessel to another identical firing process using crushed charcoal and husks. Once cooled, the "subdued fire" processing (a technique to reduce medicinal harshness) is complete. The refined cinnabar can then be finely ground and mixed with glutinous rice porridge to form pea-sized pills—one to be taken daily.

For further "transmutation" (referring to the alchemical refinement and sublimation of elixirs), one may bypass the "removing fire toxicity" step (detoxification process) and directly place the material in the alchemical chamber for "nine cycles" (repeated refinement nine times). Tradition holds that elixirs prepared through this method possess extraordinary efficacy.

Note: The term "subdued fire" (fuhuo) refers to the ancient alchemical technique of moderating a substance's properties through controlled heating. "Nine cycles" (jiuzhuan) denotes repeated refinement processes—Daoist tradition maintains that multiple refinements enhance an elixir's quality.

This scripture records two ancient alchemical techniques, primarily concerning the refinement of mercury (Hg).

The first method, the Grass and Cinnabar Mercury Subduing Technique attributed to the Prince of Huainan, requires gathering equal parts of creeping euphorbia, lotus vine stems (collected in spring), willow galls, and five-direction herb (collected in autumn). These herbs are pounded into a paste, which is then used to encase one tael of mercury. The mixture is fired with one to two catties of flame, cooled, and the vessel removed. Next, three taels of white-flowered motherwort frost are mixed with water, and the cinnabar is placed within. Firing with three to five catties of flame refines it into a precious substance.

The second method, the Three-Grade Minor Return Elixir Mercury Technique, calls for five taels each of black gourd flower, luminous cinnabar, and mercury, ground together and placed in a cauldron. Rock salt is packed tightly over the mixture, moistened with water, and smoothed flat. Five to seven holes are pierced into the surface with an iron hairpin, and a single brick is placed on top. A one-cun-deep hole is made at the center of the cauldron’s mouth, which is then placed over a flat-bottomed water flask and sealed tightly until dry. Gradually increasing the charcoal from half a catty to three catties, the cauldron is fired until it glows the same color as the flame, at which point the mercury flows into the flask below. None of the original five-tael ingredients are lost—all transform into a vivid red substance.

The refined material is then combined with fifteen taels of sulfurous cinnabar, heated until oily, stirred evenly, and ground into powder wrapped in alum paper. Separately, ten parts of desiccated lead powder are placed in a crucible as an outer layer, with one catty of purple essence powder inside. The medicine, wrapped in gold, is placed at the center, covered with more purple essence powder, and finally sealed with desiccated lead. Yin Qi is slowly expelled, and once fully dry, the crucible is sealed and fired in a furnace with one catty of flame for sixty days. If the firing is interrupted, an additional five days are required. The resulting substance, called Purple-Gold Cinnabar, is ground—one tael of it mixed with ten taels of mercury—and left covered for three days. Sealed with an iron lid, it is fired with sixty taels of upper flame and four taels of lower flame for three days and nights, yielding a silver-like substance. The remaining material can be reground, combined with half a catty of sulfurous cinnabar, and refined again over sixty days to produce Divine Purple Cinnabar.

This passage describes two ancient Daoist methods for refining elixirs, primarily involving the secret technique of transforming mercury into silver, as well as the preparation process for a longevity elixir called the "Minor Cyclic Elixir" (Xiao Huan Dan).

The first method involves mixing two medicinal powders with one jin (approx. 500g) of mercury, which after being sealed for one day naturally forms silver. This silver is then ground into powder again, mixed with half a jin of sulfur and cinnabar, and stirred into a sandy substance. Following the same refining process for sixty days yields the "Minor Cyclic Elixir." One liang (approx. 37g) of this elixir can produce five hundred pellets, each capable of instantly transforming one liang of mercury into silver.

An even more miraculous mercury transformation method involves dropping a single elixir pellet into heated mercury. The pellet will float across the mercury's surface before disappearing, after which the mercury spontaneously solidifies. Upon cooling, it becomes usable silver. Legend holds that ingesting such pellets grants immortality, with lifespan equal to heaven and earth. Carrying this elixir in the wilderness causes all beasts to pay homage, while birds consuming it transform into phoenixes, dogs into dragons, and humans attain eternal life.

The text particularly emphasizes that only those with preordained immortal connections and names recorded in the celestial registers (xianji) may encounter these refining methods. Ordinary people cannot obtain this elixir even if they stumble upon the immortal ladder.

The passage further records two secret techniques: the "Mercury-Subduing Blue Cloth Method" (Fu Gong Qing Bu Shu) and the "Herbal Chamber Nurturing Blue-Gold Head Silver Method" (Cao Kui Yang Qing Jin Tou Cheng Yin Fa). The former requires specific herbs like creeping euphorbia, oxalis, lotus leaves, sophora pods, polygala root, and Chinese gall arranged in precise layers within a cauldron for mercury calcination. The latter involves stir-frying mercury, sulfur, and alum into sandy particles before adding powders of bletilla rhizome, Sichuan pepper, and asarum herb. Both methods demand strict operational procedures and precise fire control.

Notably, these alchemical practices specifically warn against female knowledge, reflecting the esoteric nature and gender taboos of ancient occult arts.

This passage describes several methods used by ancient Daoist alchemists to prepare medicinal elixirs, focusing particularly on techniques for "subduing mercury" (stabilizing mercury through specialized processing). Let me explain these alchemical procedures step by step:

The first method involves creating a sealed vessel. Begin by coating the interior of a crucible (a ceramic container for alchemy) with clay, then place inside it qingjin sha (a type of mineral material). Cover this with a lid mixed with shanze powder (likely mineral dust), securing it tightly with tile fragments. Seal the exterior with liuyi ni (a special sealing paste made from six ingredients) to about one finger's thickness, allowing it to dry in shade before filling any gaps. Next, set up a tripod in a large earthenware or iron pot, place the medicine ball atop it, and heat gently with "golden millet fire" (low heat), maintaining constant temperature by placing four taels of charcoal on top. After three days of such controlled heating, apply intense fire for smelting. Once cooled, remove the medicine ball and shake it—the sound produced indicates whether the process succeeded.

The second method, recorded by Sun Simiao (the Revered Master Sun), involves herbal mercury-subduing. First soak hibiscus leaves and deer-hoof herb overnight in sulfur water, then dry them in shade and grind into powder. Mix this with mercury and stir-fry in a small cauldron until sandy in texture. Wrap in paper and bury underground for two shichen (four hours)—upon retrieval, it becomes mercury sand.

Alternative methods include:

• Grinding five herbs like castor leaves and wood sorrel into powder, mixing with purslane paste and mercury, then grinding together. Cover with five-flavor herbs and smelt with ash fire until faint smoke appears, then pour into water to obtain soft sand.
• Shade-dry inverted vine and datura flowers before grinding. Boil with water using "civil-military fire" (medium heat) until dry, then stir-fry into ashes. Shape the processed mercury sand into pellets.

The most complex method, "Subduing Mercury to Form Western Sand," requires: one tael of mercury, small amounts of chalcanthite and melanterite, gentian powder, and fermented vegetable juice. Simmer in an iron cauldron over moderate heat for about two mealtimes (two hours), maintaining slight bubbling. Test viscosity with bamboo sticks—when sufficiently thick, remove and filter through paper. Incompletely processed materials can be reboiled, but always use fresh containers.

These techniques demonstrate how ancient alchemists transformed mercury's properties through elaborate procedures. The term "subduing" refers specifically to making mercury stable and controllable through physicochemical treatments. The precise control of heat and timing required in actual practice reflects the experimental spirit of Daoist alchemy.

This passage describes several methods of ancient alchemical practice (Waidan), presented in terms understandable to modern readers:

The first method involves grinding three minerals—calamine (a zinc ore), hematite, and alum—into fine powder. This mixture is placed in a ceramic crucible (gan pot) with cinnabar at the center. The pot's mouth is then sealed with a paste made of red halloysite and clam powder. Using one jin (approx. 500g) of charcoal fire, the mixture is calcined until the blue smoke diminishes, after which it's cooled to obtain the refined elixir.

The second formula uses five liang (approx. 187g) of mercury combined with chalcanthite, melanterite, and alum. The mercury is placed in an iron pot, covered with alum powder, and gently heated while adding leek juice. For refining "Gengsha" (a specific elixir), gentian powder can be added during boiling. Maintaining a slight simmer is crucial to prevent overflow. When the mercury appears dry around the edges, the mixture is cooled and carefully separated to obtain the refined substance.

The third method, called "Subduing Mercury to Form Western Cinnabar," involves taking three qian (approx. 11g) of mother gold (possibly gold leaf) cut into thin pieces, combined with seven qian of mercury ground with prickly ash water. The mixture is wrapped in honey pills containing selaginella and other herbs, then fried in sesame oil. Forty-nine trichosanthes seeds are added individually, fried until golden brown, until one-third of the oil remains. Finally, the oil is washed away for further refinement.

The last technique, "Bone-Transforming Elixir Through Mercury Subjugation," uses powdered herbs like creeping fig and selfheal mixed with refined honey to form pills. Mercury is placed in a central cavity sealed with salt. These are then placed in a cup, with the mouth sealed using clam powder mixed with vinegar, reinforced with wet paper strips.

All these methods involve mercury processing, characteristic of classical alchemical operations. Important note: These techniques employ toxic substances like mercury and should never be attempted by modern practitioners.

This passage records several specific operational methods of ancient alchemical practices, primarily concerning mercury purification and elixir preparation processes. I will explain them through three main techniques:

The first method involves creating sealing materials. First, iron nails are used to secure the position, surrounded by charcoal fire and covered with a peck of dry chaff for combustion. After cooling, the condensed substance is extracted, then rinsed with dark plum juice until white, and finally melted in a sand crucible before being poured into molds. The mentioned "wall dust" likely refers to a type of mineral powder, while "flame saltpeter" indicates saltpeter.

The second technique is the mercury fixation and sand formation method. Mercury is mixed with silver matrix, then stir-fried with coarse powders of medicinal herbs like schizonepeta, dianthus, veratrum, and red pepper. After frying until the herbs turn black, the mixture is filtered, with unformed sand undergoing repeated processing. Subsequently, radish roots are boiled in vinegar, while the mercury is layered with arisaema (a medicinal herb), honey, borax, and genkwa before being wrapped. The final step involves sealing with yellow lead and salt clay, followed by firing with gentle heat first, then intense heat.

The third method utilizes phytolacca juice (possibly a plant extract) boiled with calomel (a mercury compound). The silver powder mixture is placed in a black bottle with Sichuan pepper, sealed with halloysite and salt clay, then fired under five catties of charcoal. An alternative approach involves creating silver-mercury sand, wrapping it in black paper and boiling in pepper broth for three time periods. After cooling, it's wrapped with raw honey and Sichuan pepper, then further encased in a mixture of arisaema, gallnut, and other herbs blended with honey, before final sealing with salt clay and firing under three catties of flame.

These methods exemplify characteristic features of ancient alchemy: strict operational sequences, complex herb combinations, and precise fire control. The frequently mentioned "solid sealing" refers to using materials like salt clay to seal containers, preventing medicinal evaporation during alchemical processes. "Gentle fire" and "intense fire" respectively indicate low and high flames.

This passage documents several methods for processing mercury (Hg) in ancient Daoist alchemical practices, belonging to the tradition of Waidan (external alchemy). Here is a modern interpretation presented step-by-step:

Subduing Mercury Method

Take one qian of "mother mercury" (seed mercury) mixed with nine qian of regular mercury, placed in a shallow dish over low heat. Add coarse powder of medicinal herbs including genkwa, cnidium monnieri, five-leaf vine, euphorbia fischeriana, and eclipta prostrata, sprinkling about one large qian's worth over the mercury's surface. When fumes appear, stir with a bamboo stick until the mixture turns the color of house dust, then immediately remove the container. After filtering out the herbal ash, pour the mercury onto paper and carefully wrap it into hardened granules. If incomplete solidification occurs, repeat the process.

The formed granules are then ground in a mortar with gallnut powder and pickled plum flesh to create a paste coating. Wrap this loosely in cotton cloth tied with string. Place it in a "White Tiger Pool" (special alchemical vessel) and stir-fry until the cloth turns yellowish-brown. After removal, treat it with "passing-stage medicine" (a blend of five herbs including arisaema rhizome and pinellia tuber), then coat with a mixture of hollyhock flowers, gallnuts, and honey. Finally, seal with salt clay. Once fully dried, apply "three-catty fire" (approximately three hours of strong flame) until the package glows red-hot.

Mercury Powdering Method

Place one liang of mercury in an oil-free small pot, evenly sprinkling "Three Yellows" powder (realgar, orpiment, and sulfur) over the surface. Gently sweep with a feather for even distribution. Cover with a small dish, sealing the edges with wet paper to prevent vapor escape. From Yin hour (3-5 AM) to Mao hour (5-7 AM), heat over moderate "civil-military fire" (medium flame) in an ash bed. Increase heat from Mao to Chen hour (7-9 AM), then apply "three-catty great fire" from Chen to Si hour (9-11 AM) until the pot turns red. Upon opening, successful processing is indicated by mercury solidifying like alum with golden patterns. Finally, place in a furnace for ventilation and cast into lumps, achieving the silvery luster of high-quality arsenic ("female stone precipitate"). Scale production follows identical firing procedures.

Mercury Coagulation and Chamber Method

Grind five liang of mercury with half-liang of premium arsenic, then cook in a thick-walled iron pot over civil-military fire to create an arsenic solution. Filter through fine white silk into a dish, manually stirring until solidification. This method requires precise fire control, using specific herbs and staged heating to transform toxic mercury into cinnabar or arsenic compounds.

Note: The term "female stone precipitate" refers to arsenic's ancient name, while "Three Yellows" denotes arsenic/sulfur minerals. The "White Tiger Pool" was a specialized alchemical vessel. These methods hold historical research value but involve heavy metal toxicity—modern replication is strongly discouraged.

This passage describes several secret methods used by ancient Daoist practitioners to prepare "subdued sulfur" (fuhuo liuhuang), a specially processed form of sulfur employed in elixir-making and ritual implements.

The method of Immortal Ge Hong states: First wrap objects from a deceased person's belongings in paper and place them near living individuals to absorb vital Qi (shengqi). Then cover with alum. Use a gentle flame to calcine for fourteen days—during the first seven days use only three liang of charcoal daily, then increase to four liang for the remaining seven days. After cooling, transfer to a crucible (ganguo) for further refinement. The text sternly warns that this method shouldn't be casually taught even to one's own sons, or the lineage will perish. Elixirs carried on one's person must be secretly entrusted to family members when nearing death, with instructions to cast the medicine jar into flowing water after passing. The process may only be performed twice monthly.

Another method involves: Grinding one jin of sulfur into powder, spreading it evenly in a pot, then pouring three dou of mulberry branch ash solution (collected after rainfall) over it to cover the sulfur two finger-widths deep. Boil while constantly stirring. Test small samples—if dry, the process succeeds; otherwise continue boiling until the mixture turns lacquer-black. Transfer to a crucible and melt with three to five jin of charcoal until liquefied, then pour out to cool into solid lumps before crushing, washing, and sun-drying.

The simpler method of Master Sun Simiao requires: One liang each of sulfur and saltpeter, half liang of sal ammoniac, ground into powder and melted in a crucible before pouring into molds.

Huang Sanguan's formula combines: Four liang each of sulfur, beach stone, and alum, mixed with half bowl each of ginger juice, blade-sharpening water, and soapberry pod juice. The first three ingredients are dissolved into a thin paste, dried over fire in an iron vessel into powder, then sealed for twenty-one days.

The final method instructs: Grind two liang each of sulfur and saltpeter into powder, place in a silver pot or earthenware jar, then bury in an earthen pit for heat processing.

All methods emphasize precise fire control and specialized handling techniques, representing closely guarded knowledge of ancient alchemical practitioners (liandanshu shi).

Here we discuss several methods ancient Daoist adepts used to refine elixirs, primarily involving processing techniques for minerals like realgar and orpiment. These methods all follow the fundamental principle of "subduing fire" (removing toxicity through heating), with meticulously detailed procedures.

For refining realgar, the method recorded by Immortal Master Ge (Ge Hong) is as follows: Collect mulberry leaves during the Qixi Festival (7th day of 7th lunar month) and dry them in shade. For each liang (about 37g) of realgar, use an equal amount of powdered mulberry leaves. Layer them in a porcelain container, seal it tightly, then calcine with ten jin (about 5kg) of honey and charcoal fire. To make medicinal powder, follow this method. For treating illnesses, combine it with yellow wax and croton seeds to form pills, wrap in mercury, and apply on the navel for two days to see effects. Note that the mercury will harden and lose efficacy after six years.

Another method from the Taixu Danjing (Scripture of the Great Void Elixir) describes: Grind realgar into powder, mix with wheat paste, then wrap tightly in multiple layers of rough paper. Suspend this package in boiling water (without touching the bottom), replenishing with hot water as it evaporates. After boiling through about one dan (60kg) of water, remove and pound into fine powder. Form into wutong seed-sized pills using glutinous rice porridge, to be taken with warm wine on an empty stomach.

For orpiment refinement: Use subdued-fire naosha (a mineral salt) as base and covering, with each liang of lead matched to a soapberry seed-sized portion of borax. The Sun Zhenren Danjing (Immortal Sun's Elixir Scripture) records a more complex method: Mix half liang of leaf orpiment with two liang of naosha powder, blend with egg white, and fill into an eggshell. Coat the exterior with salt and saltpeter, dry by roasting, then wrap in yellow lead (litharge) for calcination. For use, fuse the pill with cinnabar and mercury, forming chicken head-sized pills using yellow wax.

These methods exemplify characteristics of ancient alchemy: precise herb-mineral ratios, meticulous fire control, selection of auspicious timing (like the Qixi Festival), and complex detoxification processes. Modern readers should note that these mercury and lead-containing elixirs are actually toxic - the therapeutic effects recorded by ancients require scientific verification.

Ge Hong (the Immortal Lord Ge) recorded the method for refining chalcanthite (blue vitriol): Take one liang of chalcanthite (copper sulfate crystals) and mix it with four liang of sal ammoniac (ammonium chloride) in a sealed container. Heat with three jin of charcoal fire until glowing red. During operation, first dig a pit in the sal ammoniac pile using charcoal, place the chalcanthite in the center, and then cover it with sal ammoniac. Alternatively, refined table salt (douzi salt) can be used as the covering material. Let it cure for one day before heating with three jin of fire.

Sun Simiao (the Perfected Lord Sun) employed a simpler method: Grind equal amounts of chalcanthite and green salt into powder, then smelt with intense heat until fully liquefied.

Regarding the "killing method" (deactivation) of chalcanthite: Boil hibiscus leaf juice and ginger juice in a cup until dry, then wrap the chalcanthite with fumigated frankincense chunks. Place it in a pot and heat until liquefied, then pour it into a hot iron cup to solidify and deactivate it.

Refining "subdued fire arsenic" (a method for processing saltpeter): Finely grind flame saltpeter (potassium nitrate) with white alum. Spread the powdered mixture at the bottom, place arsenic trioxide (arsenic) in the middle, and cover it with more powdered mixture. Place it in a gan pot (a refractory container) and seal it with "White Tiger ash" (a lime-based material). Heat until glowing red, then remove and cast into ingots.

Killing method for arsenic trioxide: Take three liang of arsenic trioxide, six qian of cinnabar, and six qian of "frost powder" (mercury compounds), and fill the container with an appropriate amount of saltpeter and alum. First, spread saltpeter at the bottom of a porcelain box, place arsenic trioxide in the middle, cover it with the medicinal powder, then add alum on top, and finally cover with another layer of saltpeter. Seal with salt-mixed clay, reinforce with hemp rope, and let it dry in the shade before placing it in an alchemical furnace. Heat with one jin of fire daily for three days; when removed, it should appear snow-white, indicating completion.

The method for subduing arsenic, as transmitted by the Supreme Lord Lao (Taishang Laojun): Finely grind half a liang of basin saltpeter (mirabilite) with one liang of arsenic, then place it in an oil-coated porcelain jar. Add two liang of white ash powder and heat with four jin of charcoal fire. After the fire extinguishes and cools, a snow-white powder is obtained. Mix three qian of this powder with two qian of white quartz (bai shan), grind finely, and form into pill-sized drops the size of tung seeds. Administer with freshly drawn well water to treat malaria and dysentery.

The method for subduing sulfur, as recorded in the Taixu Danjing (Scripture of the Great Void Elixir): Finely grind two liang of sulfur, two liang of flame saltpeter, and three qian of sal ammoniac. Place it in a large ingot pot and fill it with weathered "White Tiger ash." Seal the pot body with clam shell powder (oyster shell powder) mixed with vinegar.

This passage documents the detailed process for creating "jade arsenic" (a medicinal ingredient) in ancient Daoist alchemy (Waidan). The procedure consists of several crucial stages:

First, the ingredients are prepared: four taels of pure arsenic trioxide are ground into fine powder, then mixed with one tael of naphtha (a natural petroleum product) and one tael of ginger juice until achieving a dough-like consistency. This mixture is placed in a small porcelain box whose interior has been treated with ginger juice. Leaving the container uncovered, it's slowly dried over low heat to dispel yin-cold energies. This drying and grinding process must be repeated five times.

Next comes preparation of the alchemical vessel: A three-liter cast iron crucible is lined with "ginger-yellow earth" (fine yellow clay mixed with ginger juice) and compacted. One inch below the rim, a small cavity is carved and filled with weathered "white tiger powder" (likely a mineral powder), within which another cavity holds the prepared arsenic mixture. Walnut meat covers this, then the crucible mouth is sealed with yellow-earth-and-paper-fiber clay, topped with an inverted porcelain bowl to ensure airtightness.

The crucial firing process follows: The entire crucible exterior is sealed with "salt clay" (salt-mixed mud) about half a finger's thickness, then placed on a tripod and fired with five jin of flame until the vessel glows red throughout. After cooling, the arsenic crystallizes into translucent, crystal-like lumps that shimmer in sunlight—a vital ingredient for refining five-metal elixirs (Jindan).

The text notes this medicine can treat stubborn cold syndromes in both men and women, with a single millet-sized pill taken on an empty stomach with cold water. The entire process demands strict standards for authenticating ingredients, controlling fire phases, and sealing techniques, demonstrating the precision of ancient alchemical practice.

This text records ancient Daoist methods for processing minerals during elixir preparation, focusing particularly on "subduing fire" (techniques to temper and stabilize mineral properties). The alchemical scriptures of Immortal Elder Ge (Ge Hong) provide detailed procedures for treating sal ammoniac (ammonium chloride) and alum.

There are several methods for processing sal ammoniac: The first involves boiling pomegranate rind, flesh, and seeds with an ash solution from five-leaf grass (a distinctive plant commonly found in Sichuan), then calcining the mixture in a sealed vessel. The second method uses saltpeter as a base layer, sealed with clay before calcination. The third combines the mineral with powdered oyster shells or clam shells before firing. Each method emphasizes "secure sealing" (proper vessel containment) and precise fire control.

For alum processing: Select high-quality alum crystals, crush them, and mix with either creeping euphorbia (or alternatively selfheal). Seal the container with a mixture of yellow earth, Sichuan salt, and paper-reinforced clay. These procedures require strict temperature and timing control, involving repeated cycles of calcination, grinding, and solution filtering to transform the mineral's properties.

These "fire-subduing" techniques in alchemy represent early prototypes of chemical experimentation. Daoist practitioners developed sophisticated mineral transformation technologies through empirical practice. The inclusion of alternative ingredients in each formula indicates systematic record-keeping and transmission of practical knowledge during that era.

This passage describes several concrete methods of alchemical practice used by ancient Daoist adepts, explained step by step:

The first method involves elixir preparation. Begin by laying half-inch thick bricks as a foundation to secure the alchemical vessel. Heat gradually with charcoal fire until the medicinal substances melt, stirring with willow branches. After one or two double-hours (时辰), remove the fire and allow cooling before breaking the vessel to extract the powdered medicine. Next, spread two liang of tung seeds as a base layer, place cinnabar in the middle, then seal the vessel's mouth with red halloysite and salt clay, securing it with iron bars. Finally, nourish the mixture with charcoal fire - first half a jin of fire for twenty-one days, then another half jin for forty-nine days. Upon completion, grind into powder and form into mung bean-sized pills using glutinous rice porridge. Tradition holds that a single pill can transform one liang of mercury into treasure.

The second method describes the transmutation of azure gold. Grind equal parts of chalcanthite, melanterite, and green salt into powder. Coat gold sheets with a medicinal paste made from vinegar, then seal with red halloysite powder and cow dung. After drying in shade, apply alternating strong and gentle fire (文武火) for three days and nights. Finally, melt in a crucible to obtain the precious substance.

The third method is the "Long-Life Repository" technique. Use a porcelain box from Dingzhou (modern Hebei Province), sealed with Six-One Clay (special alchemical clay). Layer mercury, cinnabar, and silver powder sequentially until full. After sealing, place in a furnace and nourish with chaff fire and specific tibia charcoal for seven days and nights. Then intensify the fire for calcination. After removing the substance, add another two liang of mercury and continue nourishing for seven days. Repeat this process - each time adding two liang of mercury for seven days' nourishment - said to produce treasures continuously.

These methods meticulously document ancient alchemical procedures, including material ratios, fire regulation, and temporal requirements. The mentioned "fire nourishment" (养火) refers to gradual heating with gentle fire, while "civil and martial fire" (文武火) indicates fire intensity modulation. These techniques reflect ancient Daoist explorations of material transformation, though from a modern scientific perspective, they primarily hold historical research value.

The Compendium of Alchemical Methods by Various Masters records several operational techniques of ancient alchemical practices, here explained in modern terms:

Zihuazi's Mercury-Transmutation Method (a metallurgical technique):

Take one jin (approx. 500g) of refined red copper and one jin of Taiyuan calamine (zinc ore), grind into fine powder and filter through water washing. Add one liang (approx. 30g) of the filtered mineral mixture and stir evenly, then seal in an iron container to dry in shade. Using eight jin of charcoal in a wind furnace, calcine from Chen hour (7-9 AM) for two full days and nights. After cooling, transfer to a qi furnace for rapid bellows-assisted calcination for three hours. Remove, cleanse from residue through water washing to obtain cockscomb-red granules. Each qian (approx. 3g) of this substance can transmute one liang of pale gold into superior yellow gold.

An alternate formula: Mix one liang of gold with one liang of mercury into sandy form. Layer with green salt and yellow mineral substrate, cover with chalcanthite, and place in a "Water-Fire Balanced Crucible" (special alchemical vessel). Ignite at Chen hour and calcine for three days and nights for optimal results.

Pauper's Mercury-Transmutation Method (simplified metallurgy):

Grind one liang of mercury with fifty gold foil sheets into paste, add a large cup of coriander natural juice and boil until liquid evaporates. Filter through silk to obtain sandy matter, repeating the boiling and filtering process. Combine with four liang of yellow lead and "White Tiger Powder" (a mineral substance) using vinegar for binding, then pound thoroughly. Wrap the sandy matter in three layers of black paper, encase in a "White Tiger Receptacle" molded into flat cakes, and seal with one-inch-thick salt clay. After shade-drying, calcine until glowing red. The cooled product is ready for transmutation. If gold foil is unavailable, half-qian of "horse substitute" (an alternative material) may be used.

Envelopment Metallurgy Methods:

Four-Spirits Gold Technique: Combine one liang of raw silver, half liang of gold with equal parts halite and green vitriol, then add half liang each of sal ammoniac, sulfur, and licorice. Encase and calcine to produce "purple gold" (a violet alloy).

Cinnabar-Gold Envelopment Method:

Select five liang of premium cinnabar chunks, wrap each with five layers of gold foil, and place amid reagents for one day-night cycle. Apply half jin of fire on the first day, gradually increasing to three jin until glowing red. The cooled product remains intact for direct use.

Inner Envelopment Method from the Taixu Alchemical Classic's Golden-Blue Oil Pool:

Use seven qian of green vitriol, four liang of white alum, one and a half liang of halite, and one liang of pale gold hammered into thin sheets. Prepare a new porcelain box, first laying one liang of reagent as substrate, with subsequent steps resembling the aforementioned methods.

These techniques involve complex mineral processing, sealed calcination, and other crafts—documenting ancient alchemists' experimental attempts at metallic transformation. The concept of "transmutation" (dianhua) refers to the belief that minute substances could induce qualitative changes in other metals.

This passage documents several ancient metallurgical techniques from alchemical practice, primarily describing how to alter metals' coloration and properties through chemical reactions.

The first method involves encasing gold with mineral powders for calcination. The detailed procedure is as follows: grind six ingredients - halite, chalcanthite, alum, rock salt, saltpeter, and naphtha (or sal ammoniac as substitute) - into fine powder for the inner layer. Then prepare an outer layer by mixing soap pods with halite. Line a porcelain vessel with three to five layers of the outer mixture to form a recess, then alternately layer the inner powder with gold pieces. Seal the vessel with a tile cross-bound by iron wire, coating it with a finger-width layer of salt-clay. After drying, bury it in ashes for firing - the amount of charcoal required varies with the gold's weight. The gold will turn purple upon completion.

A simplified second method specifies: for every tael of gold, combine kaolin, white clay, alum, salt, hematite, yellow alum and sal ammoniac as powdered reagents. Layer hematite powder at the crucible's base, add half the mixture, place the gold piece, then cover with remaining powder. After tile-sealing, fire with charcoal. Note that antique jewelry requires preliminary firing to remove impurities first.

The text concludes with cinnabar processing: take 1.5 taels of silver and 3 taels of premium cinnabar (dice-sized pieces). First coat with flower honey, then boil with 0.5 tael sal ammoniac in flowing water for three "fu periods" (an ancient time unit). These methods demonstrate how ancient alchemists manipulated mineral interactions to transform metallic properties.

This passage describes the specific operational steps of the "Gushing Spring Method" (Yongquan Fa) in ancient Daoist alchemy, belonging to the Waidan (external alchemy) tradition. Here's a detailed explanation:

First, cinnabar is ground into dice-sized granules (not powdered), mixed with a small amount of mercury, alum, and lump cinnabar, then thoroughly blended. Next, a paste is prepared by combining silver powder, heavy-weight paper, finely ground ink powder, and honey from various flowers. This mixture is evenly applied to paper sheets. After drying, the cinnabar lumps are wrapped in the coated paper and tightly bound with string.

Yellow clay is then mixed with oil to form a sealant, which is evenly applied around the paper-wrapped ball to a thickness of about one finger's width, ensuring no cracks remain. The ball is lightly heated over a small flame to dispel Yin energies. A lidded oil-glazed ceramic vessel is prepared with one jin (approx. 500g) of qingyan (a mineral salt commonly used in alchemy)—half spread at the bottom, the medicine ball placed atop, then completely covered with the remaining salt. After sealing, the vessel is buried in an earthen pit surrounded by a hui chi (insulating ash layer), maintaining a half-jin fire for seven consecutive days.

After seven days, the fire is increased to two jin and maintained overnight. Upon retrieval, the salt flowers (crystals) are collected, and when the paper ball is unwrapped, the cinnabar will have transformed into a tin-like black substance. This is melted in a gan guo (alchemical crucible) into liquid form, then cast into ingots weighing four and a half liang (approx. 168g), which are subsequently filed into powder.

Next, six liang of raw cinnabar (in dice-sized granules) is mixed with the processed cinnabar powder and placed in a container, layered with salt flowers at the bottom and top before sealing. The vessel is returned to the ash enclosure, now maintained at four liang fire for seven days, then increased to two jin overnight. After cooling, superior "silver" (alchemical terminology for mercury compounds) is obtained.

One and a half liang of this product is set aside for use, while the remainder serves as base material. Additional ingredients—one and a half liang of raw "silver," two liang of cinnabar, and silver powder—are incorporated, repeating the grinding and heating process. Through such cyclical operations, when accumulated to twenty liang, the material can be cast into an egg-sized ding (alchemical cauldron).

Placing the ding over hot ash, two liang of mercury is added, its mouth covered with three layers of damp paper and topped with a yueci bowl (a type of porcelain). Gradually intensifying the fire causes the mercury to transform into "silver." Maintaining a two-jin fire for one shichen (two hours) followed by cooling yields a malleable product. Subsequently, adding two liang of mercury to this ding will consistently produce more "silver"—hence the name "Gushing Spring Method." Special preparation is required for the fresh cinnabar used in this process.

The entire procedure demonstrates how ancient alchemists attempted material transformation through complex material ratios, sealed heating, and cyclical purification. Notably, the "silver" mentioned is not actual silver but represents specific metallic compounds in alchemical terminology.

This scripture records two ancient alchemical methods: the "Silver Extraction Technique" and the "Golden Elixir (Jindan) Method."

The Silver Extraction Technique proceeds as follows: First, take five qian of mother silver and six qian of mercury, cleansing them with peppercorn-infused water. Then prepare one sheng of rice vinegar mixed with half a liang of alum, three qian of Sichuan peppercorns, lotus leaves, and two qian of aconite root. Suspend these ingredients while boiling until the vinegar evaporates completely. The resulting substance will become iron-hard. Wrap it in three layers of black paper and carry it close to the body. Next, dry-roast and pulverize borax, chalcanthite, sal ammoniac, and salt. Blend three qian of this powder with half a liang of pure honey for topical application. Encase the mixture in two layers of Kunlun paper (a special paper), cutting the paper into a six-petal flower shape and sealing it with vinegar paste. Apply one or two additional layers using sumac powder mixed with vinegar. Then wrap again in Kunlun paper with added powders of anemarrhena and fritillary bulb, bound with vinegar. For the final layer, create a sealing paste by pounding yellow clay with salt, white eel, and "thousand-mile haste" herb. Roast the package in ash fire, rotating it frequently until dry. Finally, apply uniform heat equivalent to five jin of fuel until completion.

The Golden Elixir Method involves: Grinding one jin of pure, translucent sulfur into powder, then blending it with two liang of finely powdered mountain pond salt and three liang of "northern pavilion" juice (possibly a mineral solution) that has undergone fire tempering. After thorough mixing, coat the interior of an iron box three times with high-quality ink and let it dry before adding the mixture. Heat with alternating moderate and gentle flame ("civil and martial fire") until the ingredients fully melt. Cease heating when the yin energy of the northern pavilion dissipates, allowing it to cool. Add four liang of saltpeter powder, compact the mixture, and seal the box opening with adhesive paper. Once dry, place it in a tripod sealed with special clay (made from Yanmen red ochre).

This passage provides a detailed account of two metal compound preparation methods from ancient Daoist alchemy, belonging to Waidan (external alchemy) techniques. Here is a modern interpretation of the key procedures:

The first method describes the production of golden elixir: Grind oyster shells with cockscomb-red hues and red halloysite into fine powder, then mix with "Northern Court Sand" (a mineral) solution and pound a thousand times. Place the mixture into a sealed tripod vessel, securing it tightly with iron hoops. After drying, melt three catties of lead into liquid and use a small iron ladle to pour the molten lead around the vessel until nearly full, leaving about two inches of space. Select an auspicious day (Chenghe day) to begin firing at midnight (11pm-1am), starting with six taels of fuel and increasing by one tael daily for six days before extinguishing. Upon cooling, chisel away the black outer layer to reveal golden elixir, then grind it into powder for storage.

The second technique involves refining gold powder: Combine ten taels of high-quality gold with fifty taels of mercury in a crucible. Heat until the gold turns red before immersing it in mercury, stirring with a willow stick until fully dissolved. Add three catties of salt to the gold amalgam and grind finely. Seal in a large cauldron and smelt over gentle heat to evaporate the mercury. Sun-dry the remaining gold powder, then separately grind with orpiment, rock salt, realgar and four other medicinal ingredients—all must be premium cockscomb-red varieties.

Finally, load all materials into the tripod vessel as before, coating the interior with ink mixed with rice vinegar. Apply alternating civil (gentle) and martial (strong) flames to melt the compounds into liquid. Add four taels of saltpeter powder, compact firmly, and seal with paper paste before repeating the lead-pouring sealing process. The entire procedure demands precise control of firing intensity, airtight conditions, and timing selection—demonstrating the meticulous metal transformation techniques characteristic of Daoist alchemical practice.

This scripture records several ancient Daoist alchemical methods, divided primarily into three sections:

The first section describes the "Half-Zishi Ignition" method of elixir refinement. The fire is kindled at 11 PM (midway through the Zishi period), beginning with six liang (about 225g) of fuel, increasing by one liang daily for sixty days. After cooling, the resulting elixir requires removal of its black lead surface layer with an iron chisel, revealing a purple-gold substance. Grinding just one fen (approximately 0.3g) of this powder can transmute one jin (about 500g) of mercury into "purple-polished gold" (the highest grade gold in Daoist tradition). This secret immortal technique, when mastered, suffices for spiritual practitioners.

The second technique, "Subdued Fire Northern Pavilion Method," details processing beiting sand (a mineral): First blending it with melted yellow wax into pellets, wrapping in paper, then placing in a lime-filled porcelain jar. Heating begins with three jin of fire, gradually increasing to five-seven jin, culminating in ten jin of intense flame. After cooling, the substance is suspended over a water pit in raw silk bags for three days until liquefied, used to harmonize the previous two medicines.

The third method, "Subdued Medicine Transmutation of Mercury into Gold," specifies using one fen of medicine per jin of mercury. Heated in an iron cauldron until clicking sounds occur, then repeatedly quenched in water over ten cycles until the mercury blackens into granular form. Smelting in a crucible then yields purple-polished gold.

The final "Immortal's Gold-Refining Elixir" (also called Bone-Transforming Elixir) formula combines five liang each of refined calomel and arsenic trioxide (ninefold-refined being optimal), ground with one liang each of beiting sand, niter, alum, lunar essence stone, salt flowers, and red vitriol for sealed refinement. These methods exemplify ancient Daoist practices pursuing immortality through mineral transmutation.

First, compact three or four liang of refined salt (used in alchemy) at the bottom of a glass vessel. Then place the powdered realgar ball inside, layering and compacting it with more salt. If the vessel isn’t full, continue adding salt until it is. Seal it meticulously, ensuring no cracks remain, and only after it has completely dried can it be placed into the alchemical cauldron.

At the base of the cauldron, spread one jin of lead, then secure the vessel atop it before pouring molten lead over it, submerging the vessel to a depth of three cun. Bury the entire cauldron in ash, cover it, and apply gentle heat to keep the lead in a softened state for sixty days. Once the time has elapsed, increase the fire until the cauldron glows red-hot for a full day. After cooling, reheat to melt the lead again, pour it out, and retrieve the vessel.

Open the vessel and remove the outer salt crust—inside, the elixir will appear a golden yellow, like chicken fat. Grind it into fine powder and roll it with rice into pellets the size of mung beans. Each pellet can transmute one liang of mercury into silver. For ingestion, take one pellet on an empty stomach with tea or wine to replenish deficiencies, warm the kidneys, and produce marvelous effects. Alternatively, glutinous rice may be used to form the pellets.

Another method for refining the Sublime Cinnabar of Divine Fire: Take sixty-four liang of mountain-mined silver (Daoists refer to natural silver ore as "mountain-marsh silver") and hammer it into thin sheets, then cut into chess-piece shapes. Prepare one jin of cinnabar, processed using the "hanging embryo" method (a technique where substances are heated suspended in air), dried, and wrapped in a mixture of flower stamens (a blend of various floral essences). Coat each grain with an inner layer of medicinal powder (adjuvant materials in direct contact with the main ingredient), wrap them in red silk, and sun-dry.

Place these packets in a porcelain box and nurture them with controlled fire for a month, gradually increasing the heat. After this period, transfer them to a specialized "water-fire cauldron" (a unique alchemical vessel), add two liang of refined mercury, seal it, and fire for two days and nights. Upon cooling, if the mercury has been "tamed by fire" (lost its fluidity), add another two liang of mercury and repeat the process. Continue until three jin of mercury have been used. Finally, melt the substance in a crucible to obtain the treasure.

The "hanging embryo" method in detail: Place the refined cinnabar in a cloth bag, suspend it in a new earthenware pot with ten bottles of bitter wine (vinegar) and one and a half liang of sulfur, using an iron rod to keep the bag from touching the bottom. Simmer gently until the vinegar evaporates, then sun-dry to produce the inner medicinal coating.

Next, roll the cinnabar grains in processed flower stamens, then coat them with a fine powder of borax, lead frost, and alum as the inner layer. Wrap them in red silk and sun-dry again. Finally, place them in a specially crafted silver container—this vessel must be forged from mountain-marsh silver.

This passage documents specific operational methods in ancient Daoist alchemy (Waidan), comprising three main components: silver leaf processing, vessel usage, and fire regulation.

The process begins by crushing silver leaves into pieces the size of chess pieces, then mixing them with vinegar. Half the silver leaves are spread evenly at the bottom of a ceramic container (known as a "magnetic box"), with sand distributed like planted lotus flowers to prevent contact between pieces. The remaining silver leaves are layered on top, after which the container mouth is sealed with a mixture of gypsum and alum ash, secured with crossed iron wires, and finally sealed with salt-clay. Once dried, the vessel is placed in a furnace using an earthen cauldron (capable of holding 1.5 liters), supported by a tripod below with the sealed container placed atop, covered with specialized "ten-thousand coin ash."

Fire regulation requires meticulous attention: starting with gentle heat that gradually intensifies. At mao hour (5-7 AM), gentle fire is applied, followed by increased heat at shen hour (3-5 PM). The fire must remain consistently even and uninterrupted for one full month. When the sand particles harden, the material is transferred to a specialized water-fire cauldron.

The water-fire cauldron operation involves using an iron vessel about 6-7 inches tall. After placing the hardened sand inside, two liang (about 100g) of specially prepared mercury is poured in. The iron lid is secured with iron wires for airtight sealing, with warm water maintained inside the lid. The fire regulation again progresses from gentle to intense over two full days and nights. Upon cooling and opening, if successful, another two liang of mercury is added—this process repeats until reaching a maximum of three jin (about 1.8kg) mercury. The final product, when melted, transforms the mercury into a supreme treasure.

The text further records the "Divine Immortal's World-Saving Technique" formula: four liang of white arsenic as primary ingredient, combined with one liang of mercury chloride, five qian (about 18g) of mother powder, and five qian of mercury. These ingredients are ground uniformly and placed in a salt-clay sealed ceramic cauldron (previously coated inside with raw mercury), mixed with half-liang of processed alum and one liang of gypsum ground with vinegar for sealing. After drying, it enters the furnace with 2-3 jin of prepared fire surrounding the cauldron. From yin hour (3-5 AM) to mao hour, the fire gradually intensifies, requiring approximately one-and-a-half "scales" (about 15 jin) of charcoal total. After cooling, the medicine is retrieved and preserved through specific methods.

The preservation method employs a dry white ceramic container: first laying down weathered powder, then cold powder, creating a depression for the prepared medicine. This is successively layered with alum powder, cold powder, and weathered powder until full, compacted tightly before replacing the original lid.

This passage describes several specific operational methods in ancient alchemical practices, presented in distinct process segments:

Regarding the sealing of alchemical vessels: First, securely seal the vessel opening with salt clay (a specialized clay mixture), then reinforce it by binding with iron wire. After the clay seal has thoroughly dried, place it in an ash pit (an insulating ash bed) to nurture with gentle heat for seven days before removal.

The purification method using cogongrass: Take one liang of cogongrass combined with one qian of medicinal catalyst, then calcinate it with three powders (likely referring to three mineral powders), alum, and gypsum. After reducing to ash, repeat the calcination process. The specific procedure involves mixing three types of ash—mulberry wood ash, jade maiden grass ash, and purified ash—to create a lixiviated solution. Add equal parts of trichosanthes root, pork pancreas, and white clove powder, then pound the mixture ten times in a willow wood trough. From one jin of raw material, ten liang of purified substance can be obtained.

The method for creating lead-sand: Take one liang of refined cinnabar (processed vermilion) and one liang of lead. First melt the lead into liquid form, then incorporate the refined cinnabar powder while stirring to form granular sand particles, followed by yin-zhi (sealed storage).

Detailed yin-zhi method: Burn pine needles, duckweed, water caltrop leaves, and mulberry leaves into ash, then repeatedly lixiviate with zuowei (likely referring to an acidic solution). Store the prepared lead-sand particles in this solution for two days and nights. After removal and drying, place them in a gan pot (alchemical crucible) for melting. During melting, cover the surface with equal parts alum, saltpeter, and salt powder. The molten liquid poured out becomes "treasure." The final product should be stored in a divine chamber (specialized alchemical vessel), though alternative methods exist if such a chamber is unavailable.

Fentai technique (separation and purification): Use a mixture of soapberry powder, charred human hair, and saltpeter as premium coloring agent. Alternatively, iron cannon residue can also achieve separation.

Four Divine Elixir formula: Combine one jin of refined cinnabar with four liang of realgar and two liang of sulfur powder, then store for one day and night before calcinating in a jar to produce new refined cinnabar. Grind this finely and add four liang of orpiment and one liang of orpiment powder, storing again for one day and night before recalcination. Repeat this process by successively adding cinnabar, sulfur, etc. The fine powder obtained after three calcination cycles is absolutely reliable.

The Triple-Jade Maiden Rebirth method (complex alloy technique): Take three liang of silver and three liang of mercury. First melt lead into liquid, then add mercury for combined frying and refinement into alloy liquid. Following the formula, incorporate eight powdered substances in equal measures: magnetite, prickly ash, arsenic stone, sal ammoniac, halite, dried alum, dried lotus root, and charred human hair—repeatedly adding to the lead-mercury liquid until the alloy turns pure white. Finally, melt three liang of genuine silver and pour the lead-mercury alloy into the silver liquid for fusion.

This passage describes several important operational methods in ancient alchemical practice (Waidan). Let me explain them one by one:

The "Jade Maiden Embryo Method" preparation process: First, take three liang of true lead (a technical term in alchemy referring to purified lead) and hammer it into thin sheets before cutting into pieces. Add three liang of mercury and one sheng of water for boiling. Then include half liang of white alum and three qian of Sichuan pepper, pounding them into a paste in a mortar and shaping into cherry-sized pellets. Place these in a cloth bag and boil in a vinegar bottle containing white alum, salt, and Sichuan pepper powder until all vinegar is absorbed. Remove the pellets, soak in cold water, then place in the "reaction chamber" (kui).

The "reaction chamber" preparation method: Take four liang of processed arsenic (after the "volatilization" procedure) and grind into fine powder to line the bottom of a porcelain box. Place the pellets inside and cover with another layer of arsenic powder. Seal the box opening with red halloysite powder while maintaining breathability. Coat the exterior with finger-thick salt-clay and dry before placing in an ash bed for seven days of controlled heating. After removal, perform a bite test—if no grassy astringency remains, it's ready; otherwise continue heating. Upon completion, remove other substances, melt the arsenic into liquid, and boil the pellets in this golden liquid for about one meal-time. After cooling and washing, melt in a clean crucible and finally pour into an oil channel to complete the precious substance. It's said three qian of this material can transmute seven qian of mao (a certain mineral) into silver.

The arsenic processing method: Combine two liang of arsenic, four liang of saltpeter, five qian of white alum, and five qian of "white tiger" (a mineral name), grinding them finely before placing in a sweet-pot furnace. Seal with five to seven layers of wet paper, maintaining moisture by regular water application. Heat with five jin of charcoal fire for half an hour until melted, then pour out to cool and crush—yielding the aforementioned base-covering medicinal substance.

The mercury fixation method: First take two liang of alum oil into a crucible, adding one liang of processed sulfur. Seal the vessel with salt-clay and heat until glowing red, naturally forming the "reaction chamber." After cooling, add two liang of mercury followed by two liang of sulfur. Cover with vinegar-soaked paper, then apply a mixture of half-dry/half-wet yellow earth blended with vinegar, finally sealing again with salt-clay.

The Method of Constructing the Alchemical Furnace:

First, arrange four ox-head bricks (specially made refractory bricks) to form the furnace, with each side featuring an upward-facing ventilation opening placed steadily. Inside the furnace, place a crucible (gan pot for alchemy) and pack the surrounding space tightly with straw ash, maintaining an outer ash layer about one inch thick. Above the ash layer, burn half a jin of charcoal continuously for seven days. The medicinal materials will transform into shapes resembling aconite or paper mulberry fruit, with a charred black surface.

After initial processing, transfer the medicinal materials into a large pot and boil vigorously into a concentrated liquid, adding a small amount of well salt. Once the salt fully dissolves, pour the mixture into molds to cast medicinal ingots. These ingots serve as the primary medicine and are mixed with alum oil (alum powder blended with rice vinegar to a syrup-like consistency). Place the mixture in a thick white porcelain bowl and heat slowly from the bottom with charcoal fire. After roughly the time it takes to eat one or two meals, uncover and inspect. When the liquid is nearly dry, allow it to cool slightly before spreading it on paper and grinding into powder for later use.

Isolation Method (Purification Technique for Single Substances):

Take one liang of high-quality silver powder and one liang of mercury, mix them in a stone mortar, and add the aforementioned medicinal powder. Grind three to five hundred times until a sandy texture forms. Filter through fine silk and transfer to a stone pot. Add a mixed solution of halite, alum, green salt, and vinegar paste, stirring continuously while boiling for three days and nights. Remove and place in a salt container (salt chamber), nurturing it with alternating strong and gentle fire (wenwu huo) for one day. After grinding again, add one liang of powder frost (mercury compound) and return it to the salt container, sealing it with salt clay. Heat continuously with horse-dung fire (low-temperature slow fire) for seven days and nights, then finish with intense fire until cooled. The resulting powder is divided into three doses of one liang each, capable of transmuting ten liang of silver.

Stabilization Method for Borax (Borax Fire-Control Technique):

Grind one liang of borax and one liang of anemarrhena rhizome into fine powder. Prepare one jin of charcoal fire and place the crucible over it. First, stir-fry half a liang of anemarrhena powder until it turns to ash, then immediately add the borax. When the borax melts into a boiling liquid, sprinkle the remaining anemarrhena powder to suppress its fiery nature and stabilize it. Crush the cooled mass and mix it with treated silver sand (gengyin sand). For use, blend with rice vinegar into a paste and apply evenly to the surface of the silver sand. After the reaction, scrape off the surface layer for reuse.

Stabilization Method for Saltpeter (Saltpeter Fire-Control Technique):

(Original text incomplete; inferred from standard alchemical practices) Typically, a layered calcination method is employed, arranging saltpeter and other minerals in alternating layers while controlling the fire intensity to stabilize their properties. Specific steps likely involve covering with plant ash and alternating heating and cooling to eliminate explosive tendencies while preserving medicinal efficacy.

This scripture records several specific methods of ancient alchemical practice, primarily involving the refinement of minerals such as arsenic and saltpeter. It must be emphasized that these techniques involve highly toxic substances and should never be attempted by modern practitioners.

Regarding the refinement of arsenic: Take one liang (about 50g) of saltpeter (xiao shi) and half a liang of arsenic, grinding them into fine powder. Create a hollow using "White Tiger powder" (a type of mineral powder), place the arsenic inside, and seal it tightly. Heat with three to five jin (1.5–2.5kg) of charcoal until glowing red, then add another half liang of arsenic, gradually increasing to four liang. The resulting "kui" (a refining vessel) can be used to cultivate "mother sand" (a foundational alchemical material), with even better results if the sand has been treated with the "harmony of the two qi" (Yin-Yang balanced state).

Another method, the "Dead Arsenic Technique": Take equal parts (one liang each) of realgar (arsenic ore) and crude saltpeter, along with two liang of alum. First, dissolve half the saltpeter and alum, then add the realgar before covering with the remaining half. Once solidified, add three liang of actinolite, two liang of white kaolin, and three liang of gypsum, grinding them into powder and mixing with water to form pellets the size of soapberry seeds. After drying, place them in a sandbox and heat with charcoal until a five-colored glow appears—this is the so-called "immortal technique."

The "Jade Maiden’s Refined Arsenic" method: Take one liang of high-quality realgar (gold-foot arsenic), wrapping it in three layers of fine cloth. Use ginger juice mixed with flour as an adhesive, then encase the medicine in a paste made from two jin of broomcorn powder and vinegar. Heat with five jin of charcoal from the hour of Yin (3–5 AM) to the hour of Shen (3–5 PM).

The "Golden Cauldron Refined Arsenic" method: Take one liang of arsenic and melt three liang of tin in a Ding kiln porcelain bowl over fire. Slowly add small arsenic pellets (soapberry-sized), removing them once they float to the surface. After cooling, grind the arsenic with an equal amount of cinnabar, then place in a crucible (gan guo) and refine in a wind furnace to produce "dead arsenic" (processed arsenic).

The "Refined Saltpeter" method: Take three liang of high-quality cinnabar, two liang of mulberry root bark, and one liang of bitter ginseng, grinding them into powder. First, place one jin of saltpeter between layers of this medicinal powder (without sealing) and heat until glowing red, transforming it into a golden, jade-like liquid suitable for crafting vessels. For use, place the saltpeter in a crucible and seal the mouth with bitter bamboo leaves.

These methods reflect the ancient alchemists' exploration of mineral transformation. However, given the extreme toxicity of arsenic and realgar, modern readers should approach these historical texts with a scientific perspective.
