《庚道集》Vol. 4

This scripture documents two specific methods of ancient alchemical practice:

The first is the "Dongpo Three Yellow Chamber Method," primarily employing three minerals: sulfur, orpiment, and realgar (collectively called the Three Yellows). Begin by pounding motherwort to extract its juice, then boil the sulfur in this liquid until no more fumes emerge. Transfer the treated sulfur to a crucible (gan pot) to melt into solid blocks. Next, mix the sulfur with orpiment in a 4:1 ratio and heat in an ash-sealed chamber for seven days, repeating the same process with realgar. During the alchemical process, materials must be replenished seven times daily while maintaining uniform block sizes. Finally, boil the processed Three Yellows in mallow juice, grind them into powder to form the "chamber" (reaction vessel). Drill holes in this chamber, place mercury inside at a 1:4 ratio (mercury to material), seal and heat for seven days to produce high-grade gold.

The second method is the "Cinnabar Pouring Technique," using half a pound of cinnabar. First simmer it in rice vinegar over low heat for one day, then add powdered herbs including aconite roots (chuanwu and caowu) among eight total varieties, continuing the boil for three more days. While still hot, wrap the treated cinnabar in mercury-coated sand particles, then alternately coat it with phoenix tree resin powder and herbal powders, layering them in a box. Place herbs at the box's base, arrange the cinnabar in the middle, and cover with another herb layer. Seal the box with a mixture of three powders including halloysite clay blended with vinegar, applying a two-finger-thick mud coating. Bury a water-filled bottle (90% full) underground, position the box over its mouth, seal the joints with salt-clay, then surround the box with fine ash-vinegar mixture and place five catties of charcoal above before ignition. When the fire reaches 60-70% intensity, cover with yellow earth.

These methods meticulously record key technical aspects of ancient alchemy including material ratios, processing sequences, and fire control, demonstrating the practical processes of Daoist waidan (external alchemy) in pursuing gold and elixir production. Specialized terms like "chamber" (kui) and "nurturing the fire" (yanghuo) reflect the technical vocabulary of Daoist alchemical tradition.

This passage documents the specific operational procedures for two alchemical methods in ancient Daoist Waidan (external alchemy): "cinnabar amalgamation" and "dragon-tiger vessel."

First, the cinnabar amalgamation method: Take ten liang of floral silver (high-purity silver) divided into five to seven pieces, and slowly simmer with half a jin of sesame oil in a Jianzhan ceramic vessel over low heat. Add mercury and the floral silver for boiling, then gradually incorporate crushed Baibu herb (a medicinal plant) piece by piece into the oil. After simmering for two shichen (approximately four hours), it will form hardened cinnabar lumps.

Next comes the pouring process: Place the refined cinnabar on a bed of the same medicinal herbs at the bottom of a porcelain container, sprinkle a layer of Wutong ash (phoenix tree bark ash), then randomly arrange the cinnabar-silver beans over the herb powder in two or three layers like planting lotus seeds. Pour two liang of mercury over it, then cover with another layer of Wutong ash and herbs. After three days of low-heat cultivation, opening the vessel reveals crystalline formations resembling jade trees in winter forests, ready for harvesting. After repeating this pouring process five times, the cinnabar develops spiritual properties and can continue cultivation without additional herbs. Each cycle allows adding four liang of mercury. When abundant "buds" (crystalline products) are collected, they can be smelted with mountain silver (natural silver ore) into beads. If the buds are cultivated with medicinal layers for seven days, each liang of buds yields two liang of floral silver beads. These superior silver beads surpass ordinary silver and can craft various utensils. Unsmelted buds can continue cultivation in the cinnabar vessel—after nine transformations they become Great Elixirs (high-grade alchemical products) capable of transmuting alum into gold, where mere traces can transform into flying sand.

The dragon-tiger vessel preparation: Take three liang of premium cinnabar and half a liang of sulfur, grind into fine powder and wrap tightly in silk. Separately, wash and sun-dry one jin of iron sand, then layer it in a refractory gan pot—first iron sand, then the medicinal packet, covered with remaining iron sand. Fire until complete calcination produces a green substance: the dragon-tiger vessel. Mix two liang of this fired sand with half a liang of raw cinnabar, grind uniformly, seal in a thick porcelain box, and incubate in an ash bed with mild heat for seven days. Repeat the process by adding another half liang of raw cinnabar to the processed sand for further refinement.

These methods exemplify the Waidan techniques of transforming mineral medicines through precise thermal control and material combinations, involving complex chemical processes. Ancient practitioners believed such refinement could produce elixirs and precious metals with extraordinary properties.

This scripture passage discusses the concrete operational methods and theoretical foundations of ancient Daoist alchemy. It is primarily divided into two parts: practical procedures and alchemical theory.

The operational section details the refining process of cinnabar (mercury sulfide): placing cinnabar in a sealed vessel and heating it for seven days, then grinding it before mixing with raw cinnabar in specific proportions for further refinement. After repeating this process until reaching a certain weight, mercury is added to continue the refining. The text particularly mentions the white crystalline substance (called "white frost") produced during this process, claiming its ingestion could confer immortality and even transform mercury into precious substances.

The theoretical section expounds the fundamental principles of alchemy: using lead and mercury as foundational elements corresponding to Yin-Yang and the Five Phases. Lead belongs to Yin, representing the Black Tortoise of the North and correlating with the Kan trigram (Water); mercury belongs to Yang, representing the Azure Dragon of the East and correlating with the Zhen trigram (Wood). Cinnabar belongs to Fire, representing the Vermilion Bird of the South and correlating with the Li trigram. The crux of alchemy lies in harmonizing lead and mercury—the intercourse of dragon and tiger (Yin-Yang harmonization)—much like the conjunction of sun and moon or the perfect balance of water and fire (Jiji), requiring mediation by the "Yellow Matron" (an intermediary agent) for success.

Finally, two specific formulas are provided: first, refining high-quality mountain silver with purified lead in specific proportions to obtain "lead flowers"; second, the operational procedure for repeatedly sublimating cinnabar with sulfur and other medicinal substances in a specialized vessel (the water-fire crucible). The scripture emphasizes that these methods must not exceed four taels in heat intensity and warns against casual dissemination of these secrets.

These contents reflect ancient Daoist priests' experimental records in mineral refinement for pursuing longevity and metal transmutation, containing numerous specialized alchemical terms and symbolic systems unique to Daoism.

This passage describes the ancient Daoist alchemical process of refining cinnabar (a red mercury sulfide mineral), belonging to the practice of Waidan (external alchemy involving mineral-based elixirs). The procedure requires precise control of firing temperatures and timing across multiple stages.

First, the cinnabar is ground into powder, sealed in an earthenware jar, and placed in a "Weiji furnace" (a specific alchemical stove). It is heated at moderate temperature for half a day, then cooled to form solid lumps. These lumps are wrapped in silk bags and suspended inside another earthenware jar, where they undergo gentle boiling for three "fu" periods (an ancient time unit totaling approximately 7.5 hours).

Next, the cinnabar lumps are boiled with herbal ingredients including climbing fig (Ficus pumila), goniothalamus herb, and ginger juice. After boiling, they are stir-fried repeatedly with alternating fresh and dried herbs until the herbs char completely, with continuous herb replacement throughout a full day's processing.

The preparation then involves creating a "herbal chamber" (a supporting matrix of medicinal plants): a mixture of oriental arborvitae leaves, iron-footed Brahmin herb (a specific medicinal plant), Chinese gallnut powder, and cardamom powder is layered in a container as base and covering. Sealed and placed in an ash-filled vessel (an insulating container), it undergoes three firing cycles with varying heat intensities: 3 taels of fire in the morning and 2.3 taels in the evening on the first day, followed by 1.7 taels in the morning of the second day.

The processed cinnabar lumps are then treated with refined honey and lead frost (a lead compound). The final stage involves proportionally combining the cinnabar with lead-treated base material in nested containers, filling gaps with a mixture of lead flowers (lead oxide) and minium (red lead). Sealed and placed in the ash vessel, they undergo 21 days of gentle firing, extendable by 7 days if results are unsatisfactory. Subsequent phased firings (ranging from 2.5 to 4 taels of heat) continue for 16-20 days until the cinnabar becomes completely "dead" (loses reactivity). Successful base material can be reused, with proportional mercury additions and several days of low-temperature nurturing required for each subsequent use.

This passage describes the specific operational steps of "nurturing mercury to form the elixir" (yang gong cheng dan) in Daoist alchemy, belonging to the secret methods of external alchemy (waidan). The entire process requires repeated calcination and mixing of various materials:

First, mercury is blended with the "mother elixir" (base material) in a three-to-one ratio through three successive mixing and calcination stages. Each time, one tael (liang) of mercury is added, totaling three taels of mixed elixir material. After pulverizing this mixture, six qian (0.6 taels) of raw sulfur is added for every six taels of elixir material. The compound is then sealed in a specialized alchemical cauldron (water-fire cauldron) and calcined over high heat until it melts into a spinning-top shape. Any unbound mercury should be scraped off and re-pulverized.

Next, the material is stir-fried in an earthenware pot until it turns red to eliminate sulfur odors—a method described in alchemical texts as "using sulfur to stir-fry into solidity" (yi liu chao jian). The original mother elixir is then reintroduced for further nurturing, termed "harmonizing the four symbols" (hehe sixiang). The resulting crimson mercury-sulfide is called the "infant" (ying'er). If the granules appear glossy and hard, they must be boiled with medicinal herbs and calcined seven more times.

Upon completion, the mercury-sulfide is washed with honey water, wrapped in lead carbonate (lead frost), and nurtured within the mother elixir. For example, half a catty of "dead mercury" (processed mercury) mixed with half a catty of mother elixir serves as the cultivation medium, capable of nurturing four taels of crimson "infant" mercury-sulfide (later used as the "longevity repository").

Fire regulation is crucial: Begin with 1.5 taels of fire intensity for 15 days, then increase to three taels for a total of 21 days. If smoke still emerges, stir evenly, reseal, and calcine for another 5–7 days at three-tael intensity until achieving complete "true death" (full transformation).

The text notably distinguishes between the "charming maiden" (chanü, unformed mercury-elixir) and the "infant" (formed cinnabar), likening their relationship to husband and wife. The specific formulation is: two taels of cinnabar (infant) paired with four taels of mercury powder (charming maiden), wrapped in paper and silk, then suspended in a container holding either viola herbs or placenta (ziheche) for cultivation. These terms reflect the Daoist alchemical tradition of anthropomorphizing minerals—a distinctive conceptual framework.

This passage describes the ancient Daoist alchemical method for creating the "Chanü Elixir" (a mercury-based medicinal compound). The process begins by simmering lotus leaf ash solution in an earthenware jar over low heat for two to three days to eliminate salt and alum odors. This is then finely ground with cinnabar and mixed with mulberry bark juice to form a paste, which is shaped into small cakes weighing approximately one qian (about 3.75 grams).

The preparation requires double-wrapping with specially crafted black sealing paper before being layered compactly in small boxes. A rhombus-shaped "Holy Mother" plate (likely a metallic sheet) covers the top to ensure complete hermetic sealing. Additional black sealing paper separates the layers, with dead spirit's arsenic (an arsenic compound) pressed atop as a capping agent, secured tightly with iron wires.

The text explains the various names for "Chanü" (literally "Maiden"): called "White Snow" in celestial contexts, "Mysterious Vessel" in earthly terms, and "Frost Powder" in human reference—all denoting mercury. Originating from cinnabar veins as quicksilver's essence, it possesses unique properties: neither turbid when stirred nor clear when settled, capable of penetrating mountain rocks while maintaining purity unaffected by contaminants. This substance was revered as both an elixir of immortality and a transformative catalyst.

The alchemical process occurs in two stages: First, refinement in a "Not-Yet-Accomplished" furnace (a special stove with fire above and water below), gradually increasing the fire intensity from one to two liang (about 37-75 grams) daily over fifteen days. The material is then transferred to a "Bright Separation" furnace, where the processed cinnabar powder combines with bare cinnabar (another mercury sulfide variant). Using identical multi-layer sealing methods, each seven-day firing cycle continues until the elixir achieves complete "death" (chemical stability). Any residual smoke or flames indicate the need for further processing. Throughout, meticulous sealing and precise fire regulation remain paramount.

This passage describes the "Jade Field Crucible Method" (Yutian kui fa), an alchemical container and technique in Daoist Waidan (external alchemy). It details the step-by-step process of refining elixirs using cinnabar and other materials.

First, the cinnabar powder is prepared: If there are six liang (ancient weight unit, 16 liang = 1 jin) of cinnabar powder, set aside four liang separately. To the remaining two liang, add another two liang of raw powder, mix thoroughly, and form into cakes to be placed in the cinnabar crucible. Fire is applied according to specific methods. After completion, combine this with the previously set aside four liang, totaling half a jin (eight liang). Only then can this material be used to refine "White Snow" (a type of elixir).

For refining "White Snow," take half a jin of the Jade Field Crucible material and add four liang of raw powder, forming it into bean-sized pellets. Wrap these in silk cloth, suspend them, and slowly boil for one or two cycles using filtered liquid from lotus leaf ash or soapberry ash. Then coat them with a medicinal mixture of raw orpiment and realgar (sheng cixiong), lead frost, and vinegar. Seal this in the Jade Field Crucible and refine over gentle fire for fifteen days. If the medicinal properties are not fully transformed ("truly dead"), continue refining for two or three more days. Once successful, two qian (1/10 liang) of this material can transmute one liang of ordinary material into an elixir.

Fire control is crucial: First use one liang of fire for five days, then increase to 1.2 liang for another five days, and finally use 1.5 liang until the cycle completes—yielding four liang of "White Snow." Repeat this process with additional raw powder to ultimately obtain half a jin of "White Snow," which can then be used to refine the higher-grade "Divine Talisman Great Elixir."

For the "Divine Talisman Great Elixir," use half a jin of White Snow as the crucible base. Form four liang of raw powder pellets into small bean-sized pieces, then boil for one cycle with half a qian each of ginger juice, lotus root juice, and raw orpiment/realgar. After washing, wrap these in White Snow, seal them in the White Snow crucible, and refine with fire at the "Bright Li" (specific directional alignment). Fire control follows the same progression as before, ultimately yielding four liang of "Divine Talisman." Repeating this process produces half a jin of "Divine Talisman," which then serves as crucible material for even higher-level alchemy.

This passage describes two primary methods of Daoist alchemy (Waidan), employing materials such as cinnabar, mercury, and arsenic. The first technique uses a divine talisman (fulu) as its foundation, combining it with cinnabar and mercury under precisely controlled heating to produce elixirs.

The detailed procedure involves taking four taels of specially prepared cinnabar, pouring it through a goose feather tube into the alchemical vessel (known as the "divine talisman crucible"), then adding one tael of mercury. After three days of controlled heating, jade-like elixir sprouts (danya) form. These sprouts require no further refining—they're simply cut into dice-sized pieces and returned to the vessel for fifteen more days of cultivation, ultimately yielding a prized elixir. Tradition holds that just one qian (about 3.7 grams) of this substance can transmute one tael of mercury into treasure, with the process being repeatable indefinitely—earning it the name "Great Medicine of Immortality."

The second method, called "Dan Yang Bone-Transformation Technique," combines processed arsenic with powdered placenta in specific ratios, heated gradually from gentle to intense flames in a gan pot (specialized alchemical cauldron). This approach proves particularly effective for refining powdered frost elixirs (fenshuang). The procedure further incorporates mercury, salt, alum, and saltpeter—finely ground and slowly heated in a water-fire cauldron (shuihuo ding), concluding with boiling in lotus leaf ash water.

An alternative variation involves boiling arsenic in spinach juice, then mixing it with powdered smithsonite (a zinc carbonate mineral) and jujube pulp to create a paste. This mixture coats the cauldron's base before adding bones and processed arsenic, with the vessel then packed full of salt and fired until glowing red—purportedly yielding superior silver.

These alchemical methods exemplify the ancient Daoist pursuit of longevity and metallic transmutation through exact material proportions, meticulous fire control, and ritualized procedures. Modern readers should note these techniques employ highly toxic substances like mercury and arsenic—absolute caution is advised against any attempted replication.

This scripture meticulously documents the specific procedures and fire regulation methods of the "cinnabar chamber leaching technique" in ancient Daoist alchemy (Waidan).

Regarding fire control, it emphasizes mastering the alternating use of civil and martial fires (gentle and strong heat), applying gradual heating from top to bottom, with the bottom fire being most crucial. This method proves remarkably effective for sealed alchemical operations and represents the highest secret technique in elixir cultivation—even intense heat won't cause medicinal potency to dissipate.

The sealing material preparation method: Take one jin of "tiger bone" (likely a mineral substance), half jin of clay powder, and half jin of another powdered ingredient. Grind them to extreme fineness and sift. Add well water and pound repeatedly with a stone pestle until forming a glue-like paste for later use.

Waterproof oil preparation: Select high-quality shards of celadon porcelain, grind finely, then stir-fry in an iron wok over fierce flames while adding equal parts bamboo leaves and rush pith. When the porcelain powder turns ashen, wrap in fine silk cloth and filter with well water to obtain an oil-water mixture. This solution provides exceptional sealing properties.

Detailed container sealing procedure: First twist Tang letter paper (a special paper type) into pointed strips to plug gaps firmly, then smooth with the prepared paste. After drying completely, apply another paste layer before final sealing with salt clay. For pinholes or small openings at the base or sides, first apply a thin paste coating, then attach two or three layers of letter paper before applying a thick paste layer (about 1 cm). Finally, coat with the oil-water mixture and seal with salt clay. The author particularly emphasizes this as the supreme sealing method.

Cinnabar processing: Take half jin of cinnabar ore and simmer slowly in premium rice vinegar for three "fu periods" (approximately 72 hours), adding four liang of herbal powder until completely dry. After cleaning, immediately wrap each piece while hot with mercury-coated sand particles—incomplete wrapping will damage the cinnabar. Coat the wrapped pieces with honey, roll in powdered sterculia resin (a medicinal ingredient), then apply more honey and herbal powder before drying for storage.

Chamber loading method: First lay medicinal herbs at the box bottom, arrange the processed cinnabar pieces neatly, then add another herb layer—repeat this stacking three to five times. Finally, seal box seams with halloysite clay about two fingers thick, repairing any defects. After air-drying, apply an outer salt clay seal. Simultaneously bury a 90% water-filled bottle in a clean location (likely serving as a fire observation device).

This passage describes the detailed "pouring method" for refining longevity elixirs in ancient alchemical practice, requiring precise control of firing temperatures and material ratios:

First, prepare a bottle filled with medicinal liquid, its mouth leveled with the ground, above which a box is securely fixed. Seal the connection between the box base and bottle mouth with clay, particularly reinforcing it with a mortar mixture of wood ash and vinegar.

Stack five catties of charcoal atop the box to kindle a fire, allowing it to burn naturally. When the flames reach 60-70% intensity, cover them with yellow earth. The following day, remove the herbal ashes to obtain half a catty of cinnabar (a red mineral), its granules resembling silver beans in size.

Next, prepare nine medicinal ingredients: Sichuan aconite, wild aconite, pepper, Sichuan pepper, coptis root, cibotium rhizome, arisaema tuber, pinellia tuber, and wutong tree bark (Phoenix tree), half a catty each. Additionally, take five taels of mercury and five taels of floral silver divided into three to five pieces, simmering them in sesame oil within a gan pot (alchemical ceramic vessel) until coagulation occurs.

The refinement process requires repeated cycles: reheating and coagulating the silver-mercury amalgam until the mercury is completely exhausted. After cinnabar formation, employ the pouring-and-nurturing fire technique. The text mentions the "lead-sand resisting fire" method - when smoke ceases to emerge, it signals the completion of this shortcut-crafted creation elixir.

The inner layer requires only these nine medicines, while the outer layer relies entirely on lead's function. The analogy "when lead leaves its mother, the son follows his bride" illustrates lead's interactive relationship with other materials.

In practical operation: spread the refined cinnabar as the herbal base layer, then sprinkle wutong bark powder, arranging the cinnabar evenly in two or three strata. Pour two taels of mercury over it, and after three days of nurturing, opening the box reveals crystalline formations resembling jade trees in winter forests - these are ground into ultra-fine powder.

This process repeats five times: laying herbs, arranging cinnabar, sprinkling winter-forest powder, and pouring mercury. After five cycles, the cinnabar gains enhanced efficacy and can be used directly as longevity medicine without further herbal bedding. Finally, take four taels of mercury to harvest the crystals - larger quantities can be made into silver pearls or white numinous cinnabar. Nurturing one tael of sprouts (crystals) with two taels yields supreme immortal silver in seven days - an extraordinary top-grade elixir.

This intricate, precision-demanding refinement process reflects ancient alchemy's exploration of material transformation, involving chemical reactions among mercury, silver, lead and other metals.

This passage describes several methods used by ancient Daoist practitioners for refining elixirs and transmuting metals. The text first explains that silver can serve as a foundational material. Through special processing of the "Three Yellows" (realgar, orpiment, and sulfur) or "Yellow Sprouts" (a technical alchemical term referring to preliminarily refined elixirs), one can use it to transform mercury into a superior purple-gold elixir. Alternatively, if not used as base material, it can be placed in cinnabar and refined nine times to produce an advanced elixir capable of transmuting ordinary ores, copper, or iron into gold. Consuming even a tiny amount of this substance was believed to confer immortality.

The text then details a cinnabar refinement method requiring a plant called "Golden Lotus Grass" (also known as Yellow-flowered Chickweed, Step-by-Step Lotus, or Immortals Sitting in Opposition). The process involves crushing the plant to extract its juice for boiling cinnabar. During the hottest summer days (the three fu periods), the mixture is sun-dried, wrapped first in herb residue, then in Kunlun paper, and finally sealed with salt-clay. After calcination from gentle to intense heat until complete cooling, one obtains "True Dead Cinnabar" (indicating thermally stabilized cinnabar). A simplified version involves wrapping cinnabar directly in herb residue, placing it in a vessel filled with yellow clay, sealing with salt and clam powder, and refining for seven days with "two-liang fire" (a specific alchemical term denoting precise heat intensity).

Once True Dead Cinnabar is obtained, it can be combined with realgar, orpiment, and "Lead Yellow Flower" (a yellow substance derived from lead processing) in specific proportions. The mixture is ground together, then placed in a crucible heated to extreme redness. When the drugs melt into liquid under intense heat and subsequently cool, the precious substance forms. This method can process mercury—four parts mercury mixed with one part of the aforementioned elixir, refined with two-liang fire for three days, causes the mercury to "die" (lose fluidity) and sprout bud-like formations. These can be cultivated repeatedly, yielding valuable alchemical materials.

The final section explains how to obtain Lead Yellow Flower: Roll stems and leaves of wild mint into small balls soaked in juice (adding more if insufficient liquid). Place one liang of yellow lead in a crucible, calcine until red-hot, pierce a hole to insert white aconite, then calcine intensely until liquefied. After cooling, Lead Yellow Flower emerges, resembling orpiment in color. The remaining lead settles at the crucible's bottom as silvery-white residue. Pouring this lead solution over True Dead Cinnabar for calcination produces another precious alchemical material. The text emphasizes these are all secret techniques of immortals.

These methods demonstrate the sophisticated material processing and fire control techniques in ancient alchemy, where specific combinations of plants, minerals, and refinement procedures were employed in attempts to achieve material transformation and create elixirs of immortality.

This passage describes several methods used by ancient Daoist adepts for refining elixirs, primarily using cinnabar (mercury sulfide) as the base material. The first method involves taking one liang (about 37 grams) of cinnabar, crushing wild kudzu to extract its juice for soaking the mineral. After boiling until dry, the cinnabar is wrapped in kudzu residue and placed in a crucible, sealed externally with salt-clay. It's then calcined with three jin (about 1.8 kg) of charcoal fire. Once cooled, the cinnabar transforms into non-volatile "dead cinnabar," which can then be used to transmute lead, silver, and other metals.

The second method combines cinnabar with turmeric from turtle shells and pinellia rhizome powder, boiled in water throughout the three summer heat periods (sanfutian). The mixture is then blended with honey to encase the cinnabar before calcination in a gan pot (special ceramic vessel for alchemy). Later, realgar (an arsenic-containing mineral) may be added for further smelting.

The third technique uses anemarrhena rhizome powder as both base and covering for the cinnabar during calcination. Another variation involves wrapping cinnabar in multiple layers of calcined herb (possibly a medicinal plant), bound tightly with iron wire, then stir-fried with angelica dahurica and aconitum herbs before mixing with rice vinegar into a paste for gan pot calcination.

The text further details a method for creating "Ling Sheng Kui" (a sacred elixir container) using sulfur: the mineral is decocted for two days with gallnut and scutellaria herbs, then coated with egg white in a box and fumigated for seven days until the sulfur turns golden. This processed sulfur can cultivate "erhuang dantou" (a primary elixir substance) within fourteen days, which in turn can induce marvelous transformations in cinnabar.

These methods document how ancient Daoists employed complex herbal processing and sealed calcination techniques to alter mineral properties, ultimately creating elixirs. The "dead cinnabar" refers to processed non-volatile cinnabar, while "zuo kui" denotes specially prepared elixir cultivation vessels. The processes reflect sophisticated material transformations central to Waidan (external alchemy) practice.

This passage details the esoteric Waidan (external alchemy) technique of "subduing mercury to form the elixir" in Daoist alchemical practice. The process unfolds in multiple stages:

First, one must prepare a precious crucible (a sealed alchemical vessel) and process five liang of mother cinnabar (primary alchemical material) using specific methods. Each liang of mother cinnabar is divided into four or five portions, arranged in the vessel like planted lotus seeds. After seven days of sealed cultivation, the vessel is opened to extract the mercury-cinnabar compound. The practitioner then selects the "genuine subdued dry mercury" - a precious material resembling white willow catkins, revered as the "essence of heaven and earth" capable of endowing all things with spiritual potency.

The "mercury infusion technique" proceeds as follows: using previously refined cinnabar as the Danji (foundation material), it's crushed to the size of mung beans. For instance, with ten liang of base material, one first infuses five liang of liquid mercury, sealing it for seven days. After unsealing, it's resealed for five days of empty cultivation to obtain solid dry mercury. These five liang of dry mercury undergo another seven-day cultivation cycle, repeating the process until finally producing ten liang of "Divine Snow Elixir."

The "dry technique" employs ten liang of "Vermilion Numen" as primary material, combined with three sacred herbs: sheep's hoof root, gentian, and achyranthes root to cook the mercury. The infusion occurs in two phases: celestial infusion (four liang) and earthly infusion (three liang), each followed by seven-day cultivation before unsealing. The resulting twenty liang of mercury treasure is divided - ten liang serve as "elixir foundation" while the remaining ten become "mother matrix" (seed material) capable of infinite transformations.

Finally, the method for "subduing and infusing to produce dry treasure and cosmic mercury": using a twelve-liang cauldron, place two liang of infused treasure mercury at the bottom, ten liang of raw mercury above, then cover with two qian of "genuine subdued cinnabar." After sealing with silk paper, slowly brush-calcinate with sheep's hoof root juice until the mercury is gradually subdued. This entire process demonstrates the Daoist alchemists' meticulous control over material transformations.

This passage describes the "Method of Elixir Transformation" (a technique for enhancing elixir quality through multiple refining cycles) in ancient alchemy. It begins by detailing the process of crafting elixir vessels: sealing medicinal ingredients in earthenware jars, sealing the openings with a paste made from sheep's hoof herb roots, then burying them in a charcoal pit for overnight calcination to produce the elixir.

The text then explains the secret five-stage transformation process:

The first stage involves mixing cinnabar (mercury sulfide) with "spirit sand" (lingsha), using alum mother as the reaction vessel for refinement.

The second stage cultivates "old man's beard" (a crystalline elixir formation) within the cinnabar vessel—a substance formed by absorbing the essence of heaven and earth, capable of processing mercury.

The third stage uses accumulated "old man's beard" as the vessel to refine "jade shoot and jasper branches" (an advanced elixir manifestation).

The fourth stage combines equal parts "jade shoot and jasper branches" with "old man's beard" to create a superior "sacred crucible" vessel for transforming cinnabar into divine elixirs.

The fifth stage employs this cinnabar with the sacred crucible to produce the "great medicine of yin and yang" (the supreme elixir balancing complementary forces).

The text further describes the effects of the sevenfold-refined golden elixir: enabling mortals to undergo bodily transcendence into immortality, granting supernatural control over sun, moon, and cosmic forces. It concludes with instructions for crafting "elbow-pocket divine medicine": using the aforementioned sacred crucible to cultivate "frost powder" (mercury compounds), forming pills for repeated refinement until producing "divine snow elixir"—said to transmute "red silver" (possibly copper).

Additional methods include calcining cinnabar by grinding it with realgar, then repeatedly boiling with yellow-flowered chickweed to extract a medicinal solution for mixing with cinnabar. These techniques embody the ancient alchemical pursuit of material transformation and sublimation.

This passage details several methods for preparing "dead cinnabar" (processed cinnabar that loses its original properties for alchemical use) and techniques for refining sulfur into elixirs.

The first method involves wrapping cinnabar in grass, coating it with a plaster made of gypsum powder and honey, then sealing it with salt clay. After drying, it's gradually heated from gentle to intense flames until glowing red. Once cooled, the cinnabar becomes liquid and loses its original properties. Gold leaf, lead white frost, and realgar can then be added for stir-frying before final calcination to produce "golden cinnabar" suitable for transformation (in alchemical processes) or as a foundational material (gui) for elixir-making.

The second method uses one tael of cinnabar mixed with half-tael portions each of Huangyaozi (a special yellow medicinal tuber from Wanzhou resembling eggs) and qu mai (dianthus), ground into fine powder. The mixture is blended with fresh mugwort juice, with half placed at the crucible's bottom, the cinnabar in the middle, and the remaining half on top, gently pressed. After sealing with two layers of wet paper and water paste, it's dried and gradually heated to redness, transforming the cinnabar completely.

The third technique involves boiling cinnabar suspended in a decoction of mulberry root bark, wolfberry, arisaema, and aconite for three fu periods (approximately 72 hours). The processed cinnabar is then combined with borax, indigo, alum, sal ammoniac, and mercury powder, wrapped in vinegar and calcined.

A simpler fourth method uses motherwort and dock leaves as bottom and top layers, sealed and calcined once with five jin of fire intensity.

Finally, the sulfur refinement process is described: boiling in rehmannia juice for seven fu periods or in indigo juice for twenty-eight days. The sulfur separates into "celestial sulfur" (floating), "human sulfur" (semi-floating), and "earth sulfur" (settled) - all crucial alchemical materials.

These methods exemplify the Daoist alchemical tradition's meticulous requirements for material processing, employing complex herbal combinations and precise fire control to transform substance properties. The term "fu" here refers to the fundamental transformation of material properties through specific processing techniques.

This scripture primarily documents several methods from ancient alchemical practices, involving the processing and combination of various minerals. It first describes the reaction process between mercury and sulfur: mercury is mixed with sulfur in stages, adding two taels of mercury each time before finally incorporating other materials. A crucial emphasis is placed on avoiding contact with iron vessels during preparation—only earthenware (ceramic) pots must be used for boiling and refining.

The text details the use of plant-derived juices: one method involves extracting natural juice from leek flowers, boiled in earthenware for seven "shichen" (approximately 14 hours). Another technique uses juice pressed from the white flowers of motherwort (Leonurus japonicus), extended over two to three days of boiling if the effect is insufficient. The motherwort residue is laid at the bottom of the vessel, with gentle heat applied initially before intensifying to fierce flames for three to five days. It also mentions boiling sulfur with juice extracted from pounded water banana plants.

The "Four Yellows and Four Sands" represent a critical alchemical combination: the "Four Yellows" comprise high-quality realgar (from water caverns), imported sulfur, foliated orpiment, and arsenic minerals; the "Four Sands" include cinnabar, sal ammoniac (ammonium chloride mineral), "Western Companion Sand" (a mineral from the Western Regions), and iron filings. During preparation, the iron filings are first ground with rice vinegar, stir-fried until red-hot, then blended with other medicinal ingredients.

"Frost Terrace" refers to "powdered frost" (a refined mineral product obtained through sublimation), highlighting the principle of Yin-Yang balance: eight Yang-natured medicinal materials are paired with one Yin-natured ingredient (the powdered frost), termed "the aged Yang seizing the young Yin." The ingredients must be ground three thousand times, roughly equivalent to a weight of one jin and two taels.

The method for using "Lord Ge" (purple kudzu, a medicinal plant): approximately five jin of peeled and pounded juice is mixed with the aforementioned nine ingredients to form a paste. Sun Simiao (the Immortal Sun) regarded purple kudzu as the essence of Earth, capable of subduing the properties of the Four Yellows and Four Sands.

Finally, the phrase "the Hall of Gold demands three wrappings" describes enveloping the prepared medicinal paste in three layers of gold foil. The text concludes by noting that the Great Elixir Formula of the Supreme Cavern Mystery (Taishang Dongxuan Dandan Jue) was a secret alchemical doctrine concealed by the Heavenly Sovereign in a jade casket. Only those with utmost sincerity, purified through fasting and ablutions, and who solemnly pledge before the Jade Emperors of the Three Palaces (the three highest Daoist deities), are deemed worthy to study it.

This scripture details the operational procedures of the "Jade Water Method" in ancient Daoist alchemy (Waidan), comprising three main stages: furnace construction, medicinal preparation, and metal transmutation.

First, it explains that "Jade Water" refers to green salt (a mineral salt), considered the essence of water. The salt must be packed into a sand or iron container, tightly bound with iron wire, and sealed with materials like red halloysite, white clay, salt blossoms, and oyster shells. The alchemical furnace should stand three chi and two cun tall (approx. 1 meter) and one chi eight cun wide (approx. 60 cm), with a water vat of matching dimensions buried beneath—called "Lian Yin" (to retain Yin energy). Constructed from new bricks, the furnace holds the medicinal pellet at its center, covered with light ash. The fire must be maintained at a distance of eight cun and four fen (approx. 28 cm), mirroring the span between the heart and kidneys. The practitioner must observe purification rituals (Zhaijiao), retreat to a quiet chamber for three days, and add charcoal at the four cardinal hours (midnight, noon, dawn, and dusk).

Next, the medicinal preparation: The refined substance is ground into powder, mixed with two liang (approx. 75g) of mercury (the "Maiden"), and pulverized until no granules remain. Purple kudzu juice is then blended in, and the mixture is sealed as before. Emphasis is placed on harmonizing inner heart-fire with external flame, akin to the cosmic resonance between sun, moon, stars, and the Five Phases (Metal, Water, Fire).

Finally, the metal transmutation method: The refined pellet is ground finely; a bean-sized portion placed in a clean box will emit light. A single pellet can transform five liang of mercury—placed in a Jianzhan bowl (ceramic) over boiling water, sprinkled with the powder, and covered with damp paper before intense heating. A faint drizzle-like sound precedes a final silk-rending crack, whereupon the mercury becomes premium malleable silver.

For five liang of pure silver, adding three pellets in three stages yields red gold; five liang of lead-free copper treated with two pellets in two stages produces Danyang silver (high-grade silver). These operations strictly adhere to designated timings and fire regulation.

The Collection of Golden Methods records a remarkable elixir formula. If ordinary people take this elixir, it can cure various severe illnesses regardless of the patient's age. The preparation method involves repeatedly calcining the medicinal ingredients, grinding them into powder, then mixing with jujube pulp to form mung bean-sized pills. One pill should be taken each time on an empty stomach, swallowed with freshly drawn well water at dawn. Tradition holds this regimen can prolong life and provide immunity against all diseases.

The scripture particularly emphasizes the secrecy of this alchemical process—it must never be carelessly disclosed, lest it bring misfortune upon nine generations of ancestors. The phrase "transforming ordinary ground into an immortal's abode" alludes to the elixir's miraculous power to turn common places into celestial realms. Note that in Daoist alchemy (Waidan), "calcination" refers to the specialized process of repeated fiery refinement of herbs, while "well-flower water" specifically denotes the first bucket drawn at dawn, believed to contain the purest spiritual energy (Qi).
