Essential Formulas of Great Divine Cinnabar from the Jade Cavern: A Modern Interpretation

This text preserves the alchemical teachings left by Elder Zhang Guo (a renowned Tang dynasty Daoist master) at Mount Guye, focusing on methods to distinguish the quality grades of cinnabar—a crucial mineral substance in Daoist alchemy.

First Grade: The Secrets of Cinnabar Identification

Cinnabar embodies the primordial spiritual essence of all things, belonging to the southern fire element. It carries poetic names like "Crimson Dragon" and "Vermilion Bird." Quality grades are categorized as follows:

1. Superior grade: Mined from stone caverns in Chenzhou and Jinzhou, displaying varied hues

2. Medium grade: Sourced from Jiaozhou and Guizhou

3. Inferior grade: Found in Hengzhou and Shaozhou

These distinctions originate from varying concentrations of celestial purity (qing) and earthly turbidity (zhuo) in their Qi (vital energy). Cinnabar refined from pure upright Qi can reveal profound mysteries, while those containing partial Qi still confer longevity.

Characteristics of superior-grade Luminous Cinnabar:

• Extracted from Chen-Jin mountain stone formations
• Naturally forms on white stone beds
• Ideal specimens cluster in groups of 12 or 9, forming a mineral "throne" (crystal cluster)
• Exhibits unopened red lotus coloration with dazzling radiance
• Central master-crystals weigh over 10 taels, surrounded by 6-8 tael subordinate crystals
• Outer layers typically contain 1-2 dou of mixed-grade material
• Emits red glow through scarlet silk when placed at night
• Horse-tooth shaped specimens with white surface sheen qualify as top-grade "Equine Tooth Cinnabar"

Medium-grade Equine Tooth Cinnabar:

• Resembles mica with white luminescence

Superior-grade Violet Numinous Cinnabar:

• Bamboo shoot-shaped with purple-red tones

Inferior-grade Violet Numinous Cinnabar:

• Angular flakes with bluish glow

Jiaozhou and Guizhou varieties:

• Lotus-shaped glossy specimens rank as superior
• Semi-transparent granular forms count as medium grade
• Transparent flake varieties classify as inferior

Hengzhou and Shaozhou purple cinnabar:

• Red-glowing ore-extracted specimens are inferior grade
• Transparent granules from stream deposits become ingestible after proper refining (fulian, alchemical processing)

(Note: "Throne" denotes natural mineral clusters; "fulian" refers to specialized alchemical preparation techniques)

Essential Instructions on Cinnabar from the Jade Cavern (Yudong Da Shen Dan Sha Zhenyao Jue) – Modern Interpretation

This scripture primarily discusses the classification and refining methods of cinnabar (mercury sulfide).

First-Grade Cinnabar:

The finest cinnabar grows in earthen cavities (referred to as "seat-born"), particularly the "Sovereign Cinnabar" (Zhujun Sha) found at the center. Consuming just one refined pellet of this cinnabar can lead to ascension and immortality. Other varieties, such as "merchant cinnabar" (Shang Sha), which are not native to the southern regions, may appear lustrous but do not meet the highest standard.

Refining Method for Second-Grade Cinnabar:

1. Principle of Yin-Yang Harmony:

Cinnabar belongs to Yang (fire nature) and must be tempered with Yin (water-natured) substances. Commonly used harmonizing agents include rock salt and niter (a mineral salt).

2. Proportions:

• Premium Chen-Jin Bright Cinnabar (Chenjin Guangming Sha): 6 liang (approx. 225g) each of rock salt and niter per jin (approx. 600g).
• Second-Grade Bright Cinnabar (Guangming Sha): 4 liang per jin.
• White Tusk Cinnabar (Baiya Sha): 3 liang per jin.
• Purple Numinous Cinnabar (Ziling Sha): 2 liang per jin.
• Lower-quality mixed-colored creek cinnabar (Xitu Zase Sha): Only rock salt is needed for tempering.

3. Pre-Treatment:

• Rock salt and niter must first be roasted until glowing red.
• Large chunks of bright cinnabar should be crushed to the size of beans.

4. Refining Process:

(1) Place niter and water in an earthen cauldron and boil continuously for 100 days using intense fire (Wu Huo).

(2) After washing, transfer the mixture into a specialized crucible (gold, silver, copper, iron, or ceramic).

(3) Apply alternating Yin-Yang fire control:

• Each 5-day period is called a "cycle" (Yi Hou).
• For 4 days, use the Kan trigram (water nature) with gentle simmering.
• On the 5th day, switch to the Li trigram (Yang fire) for intense refinement.
• Begin with 7 liang of charcoal fire, increasing by 1 liang each cycle.

(4) The full process requires 24 cycles (120 days) to complete.

5. Key Considerations:

• Maintain consistent fire control throughout the process.
• The emergence of mercury (liquid metal) indicates proper heat regulation.

(Note: The "trigrams" mentioned refer to the Bagua (Eight Trigrams), specifically Kan (water) and Li (fire), representing the Daoist alchemical principle of balancing Yin and Yang energies.)

This passage describes several key procedures in ancient alchemical practices for processing cinnabar (mercury sulfide), divided into three grades of operation methods:

The first grade details the refinement method for mercurial frost:

Place cinnabar in a mortar and gently grind it with a jade pestle until the mercury fully permeates. Then transfer it to an alchemical cauldron and refine it twelve times using specific firing techniques. Each cycle requires adding two liang of charcoal and one fen of rock salt (mineral salt). After multiple refinements, two to three liang of luminous mercurial frost will form. By the twentieth cycle, when three liang of charcoal are added, about half a liang of mercurial frost as hard as gold flakes will condense in the cauldron. After twenty-four cycles, the cinnabar completely transforms into a vibrant red substance. At this stage, wrap it in salt crystals, seal it with yellow clay, and place it in a yang furnace for thirty days of intense "martial fire" (strong flame). The lighter substance can be made into pills (after removing fire toxicity), while the denser material can be refined into a golden solution.

The second grade involves metallurgical alchemy:

For every liang of processed cinnabar, use half a liang of salt crystals. First spread the salt at the bottom of the crucible, place the cinnabar on top, then heat until red-hot and hammer it a thousand times. This produces a metallic solution called "white gold," displaying a bright brass-colored luster.

The third grade explains the silver crucible mercury refinement method:

Fashion four liang of silver extracted from cinnabar into a crucible, then place it in a specially prepared oil-glazed vessel. First coat the silver crucible with a mixture of northern court sand, rock salt, and qilin scorpion (three mineral substances) blended with fermented wine, then let it dry before wrapping in two cun-thick yellow clay. Fire with chaff flames (rice husk fire) for twenty-one days, followed by three days of intense charcoal fire. After removing the clay layer, return the processed silver crucible to the vessel, add four liang of mercury (must be extracted from the same source cinnabar), and pour in five ge of water (approximately 300ml). Maintain constant water levels while refining continuously with "civil fire" (gentle flame) for fourteen days.

(Note: "Cycle" refers to alchemical repetition counts; "martial fire/civil fire" denote strong/gentle flames respectively; "ge" is an ancient volume measurement unit)

This passage describes the specific operational procedures for "transforming golden cinnabar" in Daoist alchemy, belonging to the Waidan (external alchemy) tradition. I'll explain the steps in detail:

The preparation phase begins by hammering four taels of yellow silver into a crucible-shaped vessel that fits inside a flask. Three medicinal ingredients must be prepared: one fen of Puzhou chalcanthite (copper sulfate), one tael of rock salt, and one tael of sal ammoniac. These are ground into paste with bitter wine and evenly applied to the silver vessel's interior and exterior surfaces.

The first refining process involves encasing the medicated silver vessel in yellow clay and firing it in chaff flames for fourteen days. After removing the clay, the vessel undergoes intense charcoal firing (known as "martial fire") for seven days. The processed vessel is then returned to an oiled flask containing four taels of native cinnabar and five ge of pure water, where it undergoes gentle "civil fire" heating for another fourteen days.

The cyclical refining stage requires adding four taels of raw mercury each cycle, followed by fourteen days of civil fire incubation. After drying and sealing, martial fire is applied for intense refinement. When reddish-yellow cinnabar emerges, it's collected. This process repeats until accumulating one jin of refined cinnabar.

The sublimation purification involves placing the collected cinnabar in a tripod cauldron for "flying and settling" refinement according to Yin-Yang fire phases: three days of Kan trigram water boiling followed by two days of Li trigram solar fire refining. Each five-day cycle intensifies the firing by adding three additional taels of charcoal. The final product appears as yellow-purple, arrowhead-shaped mercury frost.

The text concludes with important safety instructions: for ingestion, one tael of the elixir must first be detoxified by mixing with jujube pulp to make 360 small pills. This reflects the Waidan tradition's attention to pharmaceutical safety in elixir consumption.

Interpretation of the Sixth and Seventh Sections of The Essential Formulas of the Great Divine Cinnabar from the Jade Cavern

Section Six: The Method for Refining "Azure Gold"

Take one or two liang of cinnabar (vermilion) and grind it into fine powder using a jade pestle in a mortar. Place it in a crucible and refine it according to the firing method described earlier. After twenty cycles (approximately one hundred days), the cinnabar will achieve "subdued fire" (preliminary refinement). For further purification, follow the previous method using salt flowers (natural crystalline salt) as a catalyst, allowing the refined essence to flow down and condense into an azure-gold product. If intended for ingestion, the toxicity must first be removed while retaining its emerald-green component.

Next, shape four liang of the azure gold into a pot-like vessel and prepare the following medicinal mixture:

• Half a liang of red salt
• Half a liang of "great roc sand" (borax)

Grind the ingredients into a fine powder, mix with vinegar to form a paste, and apply it evenly to all sides of the pot. Dry it over fire, repeating the process until all the medicine is used up. Then, encase the pot in a one-inch-thick layer of yellow clay and refine it with husk fire for fourteen days, followed by intense fire (martial fire) for seven days. After removing the clay shell, place the pot into a flask and add four liang of mercury and five ge of water (the amount must not be altered). Nourish and refine this for fourteen days. Then, add another four liang of mercury and continue nourishing for another fourteen days. Once dried, apply intense fire for one full day to collect the sublimated cinnabar. Repeat this process of adding mercury and refining until a cumulative total of one jin is achieved.

Finally, place the refined cinnabar into a crucible and refine it according to the previous method: five days per cycle—two days of boiling with Kan trigram water (gentle fire) and three days of sublimation with Li trigram fire (intense fire). After sixteen cycles (eighty days), the golden cinnabar will be fully subdued by fire. If casting is desired, use salt flowers as a catalyst to allow the golden liquid to flow out, yielding pure gold. For ingestion, simply remove the toxicity while preserving the emerald hue—this refined gold can be stored indefinitely.

Section Seven: The Method for Refining "Purple-Gold Cinnabar"

Take eight liang of gold and forge it into a round crucible (with a capacity of about four ge), and use another two liang of gold to make a lid. The medicinal mixture inside the crucible consists of:

• One liang of sulfur
• One liang of red salt
• One liang of "northern court sand" (ammonium chloride)
• Half a liang of "great roc sand"

Grind these four ingredients into powder, mix with vinegar, and apply the paste evenly inside the crucible and on the lid. Once the medicine has dried, encase the crucible in a one-inch-thick layer of yellow clay and refine it with gentle fire (small flame)...

The Essential Formulas of Great Perfection from the Jade Cavern details the methods for refining "Radiant Cinnabar" and "Crimson Gold." Here's a section-by-section explanation:

Refining Radiant Cinnabar:

1. Preparation: Coat the bottom of a golden crucible with sweet earth (clay) to a thickness of about 1 cm, then suspend it in the furnace. Leave space beneath the crucible for ventilation and fire.

2. First Refining: Add four liang (≈148 g) of true mercury (quicksilver) and two ge (≈200 ml) of water. Heat continuously over gentle fire for seven days, maintaining a steady fire intensity of five liang (≈185 g). Keep replenishing water to maintain the volume.

3. Second Refining: After seven days, add another four liang of mercury and continue gentle heating for another seven days. Once the water evaporates, switch to intense fire for one day to obtain five liang of Radiant Cinnabar.

4. Cyclic Process: Repeat the steps of adding mercury, refining with gentle fire, and intensifying the fire to extract the cinnabar. In total, thirty liang (≈1.1 kg) of Radiant Cinnabar can be obtained.

Refining Crimson Gold:

1. Place the Radiant Cinnabar in the crucible and refine it in five-day cycles:

• Day 1: Boil with Kan trigram water (yin fire)
• Day 2: Refine with Li trigram fire (yang fire)
• Days 3–5: Gradually increase the charcoal fire, starting with seven liang (≈259 g) and adding two liang every two cycles. After seven cycles, increase by three liang each time.

2. After seventy days, the cinnabar will turn a bright red. At this stage, add salt crystals (as a catalyst) to refine it into Crimson Gold. Detoxification (likely a purification process) is required before ingestion.

Eighth Grade: Crimson Gold Transformation Formula

Method for Crafting the Special Golden Crucible:

1. Cast a crucible with a capacity of about five ge (≈500 ml) using nine liang (≈333 g) of Crimson Gold, and use two liang (≈74 g) to make the lid.

2. Inner Coating Formula: Sulfur, northern cinnabar (ammonium chloride), red salt, and borax, each incrementally increased by one fen (≈3–4 g) from the previous batch.

3. Mix the ingredients with bitter wine (vinegar) and apply evenly inside the crucible. After drying, seal the lid and wrap the exterior thickly with yellow clay mud.

(Note: The "liang" mentioned is an ancient weight unit ≈37 g; "ge" is a volume unit ≈100 ml. These alchemical procedures involve high temperatures and toxic substances—do not attempt to replicate them.)

This passage describes the specific alchemical procedure for "transforming into purple gold" within Daoist Waidan (external alchemy) practice. I'll explain the steps in operational sequence:

First, prepare the alchemical vessels: Cast a seven-sheng capacity cauldron using one jin of purple gold, then make a lid with five liang of purple gold. Coat the interior with a medicinal powder mixture of four liang sulfur, two liang red salt, one liang northern cinnabar, and one liang borax, blended with bitter wine to form a paste that completely lines the interior. After drying, seal with the lid.

Next, encase the cauldron in a one-cun thick layer of yellow clay. Begin with gentle fire (wenhuo, mild heat) for twenty-one days, then switch to fierce fire (wuhuo, intense heat) for seven days. After cooling, remove the clay layer and re-wrap with sweet earth, this time with a thinner 2.5-fen layer.

Place six liang of true mercury (quicksilver) inside the cauldron with three sheng (approximately 300ml) of water, maintaining constant liquid levels. After two days of fierce firing, red sand will precipitate. Collect this sand, then add eight more liang of mercury. Repeat the cycle of seven days gentle fire followed by two days fierce fire to obtain more red sand. After five such cycles, you'll accumulate thirty-two liang of divine sand.

Grind the divine sand with three liang of sulfur, then place in the golden cauldron for yanghuo (external fire) refinement. Each five-day cycle increases the charcoal by two liang for the first seven cycles, then by three liang thereafter. During firing, crimson-gold frost will emerge—collect and mix it with the sand, grind with bitter wine, then return to the cauldron. The complete process requires fourteen cycles (seventy days) to produce the final purple-gold elixir.

Important note: Before ingestion, use natural salt crystals (yanhua) as a catalyst and carefully remove the "fire toxin" (the elixir's heating properties) to achieve the longevity effects.

The Essential Formulas of the Great Divine Cinnabar from the Jade Cavern details concrete procedures of ancient alchemical practice, divided into three main sections:

The first section describes the method for refining "Crimson Frost":

• Place twelve taels of genuine mercury into the crucible with three ge (approximately 300ml) of water, maintaining constant water levels
• Apply gentle fire for seven days, keeping the crucible lid slightly aeration. Replenish water when nearly evaporated
• After seven days, intensify to strong fire for three days. Upon opening, the mercury will have transformed into crimson frost
• Repeat this process twice more, adding nine and six taels of mercury respectively, ultimately yielding thirty-three taels of Crimson Frost Cinnabar

The second section outlines further refinement:

• Grind the Crimson Frost Cinnabar with four taels of sulfur using a jade pestle for one full day
• Return to the crucible for seven-day cycles of pure yang fire (high-temperature smelting)
• At each cycle's completion, add half-ge of bitter wine (vinegar) and regrind. Twelve complete cycles (84 days) are required
• The final elixir will radiate five-colored brilliance, termed "Purple Polished River Chariot Gold"

The third section presents two specialized techniques:

• Mercury Extraction Method: Heat salt-sealed iron crucibles with small vents using special mulberry-wood fire for three days to distill mercury
• Mercury Refining Technique: Grind one jin of mercury with three taels of sulfur to produce alchemical medicine

This text meticulously records ancient alchemical protocols including material ratios, fire regulation, and operational sequences, constituting crucial documentation for Daoist alchemical studies. The mentioned "River Chariot Cinnabar" was reputed to possess the wondrous capacity for metallic transmutation into gold.

The Essential Formulas of Great Divine Cinnabar from the Jade Cavern details two key alchemical procedures:

I. Method for refining purple cinnabar mercury:

First, slowly add mercury over low heat while rapidly grinding it into a bluish sand-like substance. Transfer this into a one-liter porcelain vessel. Seal the exterior with yellow clay approximately 2 fen thick (about 6mm), then place the tightly covered vessel into the furnace. Begin with one jin of charcoal fire to temper the vessel for three days, then increase to ten jin of charcoal divided into two firing stages. Should blue flames emerge, immediately seal with diluted clay. After the fire extinguishes and cools, the mercury transforms into purple cinnabar.

II. Sevenfold Reversion Method (a cyclical refinement process repeated seven times):

Melt one jin of black lead and incorporate the finely ground purple cinnabar with vigorous stirring. Transfer the mixture to a cauldron for grinding, cover with a 2-fen layer of salt crystals, and seal for half-day firing at high heat. Each reversion follows specific operational sequences - the seventh cycle requires repeated firing with one jin of black lead. Through seven cycles of water-fire refinement, the complete transmutation of the elixir is achieved.

Chapter Twelve: Discourse on Identifying Mineral Medicines describes two alchemical materials:

1. Rock Salt:

• Formed through the congelation of yin qi, appearing as flaky stones with crystalline whiteness resembling salt grains.
• Its flavor is milder than common salt, possessing the capacity to restrain yang qi and neutralize fire toxins.
• Often used in combination with alum and sulfur to extract metallic essences and purge impurities.
• Serves as auxiliary material in the Sevenfold Reversion Method.

2. Niter (Saltpeter):

• Also crystallized from yin essence, resembling hydrated stones in form.
• Sourced from Sichuan region, sharing the properties to counteract yang energy and dissolve fire-stone qi.

(Note: The "fen" measurement unit equals approximately 3mm in ancient metrology; "reversion" refers to cyclical refinement stages in alchemy. These materials held specific functions in historical alchemical practice - modern experimentation is strongly discouraged.)

This scripture primarily discusses the characteristics and applications of several alchemical materials:

Regarding Northern Pavilion Cinnabar (a mineral substance):

It contains the Qi of yin stones and the essence of yang toxins, capable of dissolving five types of metallic ores, with efficacy comparable to sulfur. High-quality Northern Pavilion Cinnabar appears light red and crystal clear. In the "Seven Cycles and Two Chapters" alchemical method, it serves as an auxiliary material. When combined with Great Peng Sand, red salt, and sulfur in refinement, its effects are enhanced.

Concerning Kirin Scorpion (a mineral substance):

Originating from the Western Regions, it resembles purple ore in color and appears like weathered rock. It strengthens the yang nature of mercury and dispels stagnant yin Qi. Authentic specimens will exude red liquid when burned, while the ashes retain their original color.

About Stone Gall (chalcanthite):

Found in Mount Song and Mount Zhongtiao in Puzhou, it resembles lapis lazuli in form. It can transform eight types of ores into the essence of the five metals. Testing method: when applied to iron or copper and heated, it turns red; genuine specimens placed in copper vessels with water won't turn the water bluish-green after several days.

Regarding Great Peng Sand (a mineral substance):

It embodies yang Qi yet is nourished by yin Qi, resembling amber in appearance with a texture like peach resin. Its refining effects are remarkable when combined with sulfur and red salt.

Chapter Thirteen explains the essential techniques for refining the Four Yellows (realgar, orpiment, arsenic yellow, and sulfur):

These four materials all belong to the central Wuji Earth phase, containing yang fire toxicity yet capable of transforming metals. Those that maintain luster and fluidity can transmute ores into gold; when calcined, those turning white like calomel can transform the five metals into silver. Their specific properties:

• Realgar can transform iron
• Orpiment can transform tin
• Arsenic yellow can transform copper into silver or gold

This passage primarily explains the methods of using sulfur in alchemical practices and the essential techniques for refining the Purple Gold Elixir. I'll explain it in sections:

On the properties of sulfur:

Sulfur holds the most potent efficacy in alchemy. It strengthens Yang energy, replenishes Jing (essence), and returns turbid Qi to purity, ranking first among the seventy-two minerals. When sulfur encounters red salt, borax, or chalcanthite, it returns to its original state without changing color. However, when meeting rock salt, nitre, saltpeter, or chalcanthite in fire, it turns white. The methods for subduing the seventy-two minerals recorded in the Dadong Zhenjing (Great Cavern True Scripture) all require pairing with "womb-like" substances (an alchemical term referring to medicinal combinations). If equal amounts of green vitriol, lead powder, and naphtha are mixed and refined in the cauldron, the vitriol can function similarly to sulfur while also neutralizing fire toxicity to complete the transformation.

Method for refining the Purple Gold Elixir:

Take ten pounds of true mercury (quicksilver) and thirty-five taels of purple gold extracted from cinnabar that has undergone seven refinement cycles. Melt both in a specially made crucible until liquefied, then mix them rapidly off the fire into fine granules. Add five taels of sulfur, grind all three ingredients in a mortar for a full day, then transfer to the alchemical cauldron for firing. After six transformations—each requiring additional Yang energy—when the firing duration reaches the prescribed number of days, the Great Elixir is achieved. When struck, it exhibits a purple-gold hue; when ground, it becomes the finished Great Elixir.

Specifications for cauldron construction:

The alchemical furnace and cauldron must conform to the principles of the Three Powers (heaven-earth-human) and Five Spirits (Daoist cosmology). The cauldron body requires twenty-four taels of seven-times refined gold, corresponding to the twenty-four solar terms. Sixteen taels form the round cauldron body with a capacity of nine ge (measurement unit), matching the ultimate Yang number nine. The eight-tael lid corresponds to the eight seasonal nodes (like Beginning of Spring). The entire cauldron weighs twenty-four taels, with sixteen taels for the body equating to one jin (ancient measurement where sixteen taels made one jin). Seal the prepared purple-gold granules tightly within the cauldron to prevent Yang energy leakage.

Furnace construction method:

During the ten-day cycle beginning with Jia-Chen (21st of the sixty-day cycle), on the Wu-Shen day, collect pure soil from the southwest to build an altar. The altar stands two chi four cun tall with three tiers: the upper nine-cun "Heaven Gate" tier has nine apertures symbolizing the nine stars; the middle one-chi "Human Gate" tier has twelve doors for the twelve double-hours, each with shutters; the lower five-cun "Earth Gate" tier has eight windows representing the eight winds. The furnace chamber has an inner diameter of one chi three cun, within which the cauldron is placed.

The fifteenth chapter of "Essential Formulas of the Great Divine Cinnabar from the Jade Cavern" details concrete methods for elixir preparation, divided into several key stages:

The furnace construction comes first: A two-inch earthen platform must be suspended at the center of the stove, its dimensions matching the alchemical cauldron. Fire regulation must follow the patterns of Yin-Yang transformation, mirroring the twenty-four solar terms and seventy-two pentads (an ancient system dividing five days into a hou, three hou into a qi, and two qi constituting a month). During daytime before noon, use eight liang (about 300g) of fire; from midnight zi hour to noon, employ sixteen liang fire. Increase fire during yin periods and decrease during yang phases. Maintaining this fire cycle for sufficient duration produces the perfected elixir.

Material preparation requires twelve jin of northern jade salt and eight jin of pristine mysterious essence (a mineral substance). At midnight on winter solstice, these are pounded into fine powder, sifted, and placed in a clean eight-dou (approx. 80L) cauldron. Add "minor divine water" (a specially prepared medicinal solution) until 80% full, then stir continuously with a willow stirring rod over fish-eye bubble sized flames for forty-five days. White stone-like deposits will form at the cauldron's base.

For purification: After decanting the liquid, mix eight liang of worm-free soapberries with eight dou of divine water to extract juice. Filter and clarify this before returning it to the cauldron for five more days of boiling. The salt dissolves while mysterious essence precipitates as powder. After sun-drying, eight jin of purified mysterious essence powder remains.

The ninefold refinement process involves alternating civil (gentle) and martial (intense) fires through nine cycles. Every forty-five days requires one day of boiling with divine water. Note that the willow stirring rod must be crafted from healthy, knot-free southern willow branches cut precisely at noon on summer solstice, measuring two chi four cun (approx. 75cm).

Preparation of minor divine water: In an eight-dou iron cauldron, combine one jin of mercury, half-jin of cinnabar, and four liang of sulfur powder. Seal and bury three chi underground until needed for alchemical operations. Finally, add four small liang of saltpeter per jin of mysterious essence powder.

(Note: Ancient measurement units mentioned: 1 liang ≈37-40g; 1 dou ≈10L. These metallurgical processes involve toxic heavy metals—modern replication is strongly discouraged.)

This scripture describes the process of refining the "Nine-Cycle Golden Elixir" (Jiuzhuan Jindan) in Daoist alchemy, along with the preparation method for an advanced elixir called the "Great Elixir" (Dadan), also known as Divine Snow.

【Nine-Cycle Golden Elixir Preparation】

First, medicinal ingredients are ground into powder and placed in a porcelain crucible. After sealing, intense heat is applied to condense the substances. Maintaining about two inches of empty space inside the crucible, continuous firing with the strength of one jin (approx. 500g) of fuel is sustained day and night for forty-five days. Upon opening, the material is crushed, sifted, then boiled in a pot with "Minor Divine Water" (Xiaoshen Shui) for a full day and night until the water evaporates and the medicine dries—completing the first cycle.

The second cycle follows the same method, adding saltpeter before firing with alternating civil and martial fires (civil fire being gentle heat, martial fire being intense flame) for another forty-five days, followed again by boiling in Minor Divine Water. For the third cycle, four small liang (approx. 150g) of "black donkey milk" (Wu Lüru) is mixed per jin of material before applying identical heat and duration. No further ingredients are added through the remaining cycles until the ninth is complete.

The final product—called "Divine Water Flower Pool" (Shenshui Huachi)—becomes stone-hard, ringing like metal when struck yet dissolving instantly on the tongue. Buried underground it never decays, boiled it won't melt, and when shaken flows like liquid gold. This elixir can subdue birds and beasts, combine with mineral ores, transmute base metals into treasures, and instantly solidify mercury upon contact.

【Great Elixir (Divine Snow) Preparation】

Using previously buried Minor Divine Water material, cast a round crucible (capacity nine ge, approx. 540ml). Line its base with one jin of Divine Water Sacred Stone powder, cover with twenty-four liang of luminous cinnabar, then seal with medicinal clay and air-dry. After proper placement in an Eight Trigrams furnace, ignite at the winter solstice's midnight hour (zishi), aligning flames with the Big Dipper's rotation. Test temperature by hand—maintaining slightly warmer than body heat—while firing continuously for one year.

Upon opening, the cinnabar achieves "subdued fire" (fuhuo, the stabilized state after heat transformation), appearing radiant crimson like unopened red lotus buds both inside and out. Consuming one liang cures hundreds of ailments, repels evil influences, bestows radiant complexion and agile movement. Finally, these materials are repacked for further refinement.

Notes:

1. "Cycle" (zhuan) refers to alchemical repetition stages—nine cycles indicate supreme quality

2. "Subdued fire" (fuhuo) denotes the stabilized state of materials after proper heat transformation

3. Ingredients like black donkey milk and Minor Divine Water represent specialized materials in Daoist alchemical tradition

This passage describes the alchemical process and miraculous effects of a elixir called the "Divine Talisman White Snow Elixir" (神符白雪丹). The complete refinement requires nine years, divided into several stages:

In the first year of refinement, the resulting elixir appears white on the outside and red inside. Consuming just one liang (about 30 grams) of it makes the body feel refreshed and rejuvenated. Continuing the refinement into the second year, the elixir becomes pure white throughout, translucent like genuine snow. Those who ingest it will maintain youthful complexions like maidens, become impervious to heat and cold, avoid disasters, shine like the sun and moon, and attain longevity without aging.

When the refinement continues to completion in the ninth year, the elixir acquires inconceivable divine properties: it can transform birds into phoenixes and snakes into dragons. Humans who consume it immediately attain immortality. The adept gains power to summon wind and rain, receives service from jade maidens, can turn earth into gold, transform decay into wonder, and even make fools wise—fulfilling every desire. Taking it enables instantaneous ascension to immortality that very day, along with the ability to transmute stone into gold.

The seventeenth section details the cauldron preparation method: First boil two liang of alum in clear water for one day, then add two liang of salt and boil another day, followed by two liang of saltpeter boiled for a day. Finally, incorporate a small amount (about the size of a pellet) of solar essence. After drying by fire, mix four liang of true mother-substance with six liang of child-substance into a paste. Then add two liang of earth-mother boiled in water for a day, two liang of salt boiled for a day, and one fen (0.1 liang) of saltpeter boiled for a day. Seal the mixture in a stone cauldron and suspend it above the furnace for gentle nurturing by water and fire.

Each five-day cycle requires adding four liang of mercury. Gradually, white crystalline formations resembling mountain peaks emerge inside the cauldron. Continue adding mercury in this manner until reaching a total of one jin (16 liang). After ten cycles, the medicine turns half-red, at which point the cycle extends to ten days. Following another ten cycles when the medicine becomes completely red, it can be removed for one year of gentle nurturing in a special chamber, then tempered in the Hua Pool (华池), and finally detoxified in cold springs before consumption. For the second refinement stage, place eight liang of mercury and eight ge (a volume measure) of medicine into a golden cauldron to continue the process.

This passage comes from the Jade Cavern Great Divine Cinnabar Essential Formulas, a foundational Daoist alchemical scripture that expounds the essential principles for refining the Golden Elixir (Jindan):

The cultivation of the Golden Elixir (the Daoist alchemical method for attaining longevity) resembles nurturing the sun and moon—it enables one's spiritual power to multiply without limit. Through this method, all manner of precious elixirs may be produced. The transformations of the Golden Elixir are boundless and inexhaustible, impossible to fully document. The crucial point lies in practitioners personally engaging in the practice, following the elixir formulas step by step, while strictly maintaining secrecy—these teachings must never be casually disclosed.

"Jade Cavern" refers to the grotto-heavens where immortals dwell, while "Great Divine Cinnabar" indicates the supreme methods for refining the Golden Elixir. The entire scripture primarily transmits the core secrets of Golden Elixir preparation.
