《陰陽九轉成紫金點化還丹訣》

"Ninefold Yin-Yang Transformation into Purple Gold Elixir Formula" Modern Interpretation:

First Transformation:

Grind three catties of cinnabar into powder and mix with eighteen taels of Guazhou alum (a mineral ingredient). After thorough blending, spread salt crystals as a base layer in the alchemical vessel, then place the medicinal mixture atop. Cover with an inverted earthen jar, sealing it with Six-One Mud (a specialized Daoist alchemical sealant). Lady Cai (a renowned alchemist) advises applying wet clay to reinforce the jar's base and midsection. Apply alternating gentle and fierce fire (wenhuo and wuhuo) for three days and nights. Upon cooling, open the vessel and use a bird's feather to collect the transformed mercury. Should conversion remain incomplete, repeat the process until full transformation occurs. The scripture states that mercury (the River Maiden) possesses extraordinary mobility—it disperses without trace when exposed to fire, requiring the foundation of Yellow Sprout (primordial metallic essence) for stabilization.

Second Transformation:

Take one catty of previously obtained mercury and blend with four taels of sulfur (adjustable ratio). Seal the mixture in the alchemical vessel and apply alternating gentle-fierce fire for three days and nights. Cease heating when the vessel's base glows vermilion like the flames. After cooling, the substance will have transformed into cinnabar. Repeat the sealed calcination process until achieving complete crimson transformation. The alchemical canon teaches that cinnabar (essence of Wood) requires metallic Qi (Jin Qi) for progressive transmutation.

Third Transformation:

Pulverize the acquired cinnabar and follow the first transformation method. For each catty of cinnabar, combine with equal parts Guazhou alum, then seal and calcine for three days and nights. Upon cooling, use a feather to collect the reverted mercury. The scripture notes that flowing mercury (Solar Streaming Pearl) tends to scatter easily, requiring consolidation through the Qi of Golden Blossom (metallic quintessence).

Fourth Transformation:

Prepare a gold or silver cauldron (alchemical vessel) with two-to-three peck capacity. Place forty taels of premium Guazhou alum stones inside, add mercury, and decoct for thirty days until reduced to approximately five sheng. Separately prepare five sheng of saline solution to blend with the alum decoction, continuing the refinement process in the vessel.

(Note: The original text's "Six-One Mud" refers to a specialized Daoist alchemical sealant composed of seven ingredients; "gentle-fierce fire" denotes alternating intensity in heat control; "River Maiden" and "Solar Streaming Pearl" are arcane names for mercury)

This passage describes the fifth to seventh stages of the "Nine-Cycle Reverted Elixir" (Jiuzhuan Huandan) process in Daoist alchemy, specifically within the tradition of external alchemy (Waidan) that seeks immortality through material refinement. Here's a detailed explanation:

[Fifth Cycle Procedure]

1. Prepare a yin-yang furnace (a special alchemical stove with water above and fire below). Place the previously refined mercury in a one-dou capacity magnetic or iron container. If unavailable, substitute with earthenware or porcelain crucibles.

2. Add two liang of realgar, one liang of saltpeter, two fen of dragon's blood resin (a type of resin), two liang of borax, along with two fen each of malachite and crude saltpeter—all finely ground into powder.

3. Mix these powders thoroughly with viscous mercury, seal the container with the remaining medicinal powder.

4. Add three jin of mercury and three liang of alum, then ignite the furnace. Observe the fire intensity until the container glows red and the mercury fully solidifies.

[Core Principle]

The text uses agricultural metaphors: Just as rice cultivation requires viable seeds and eggs need fertilization, alchemy must follow the law of yin-yang interaction (material correspondences). Violating natural principles would be like a hen incubating infertile eggs—no chick could ever hatch.

[Sixth Cycle Procedure]

1. Take the solidified mercury from the fifth cycle and place it in an iron cauldron.

2. Add two liang of realgar, five liang of sal ammoniac, and one liang of borax—all ground to powder.

3. Gradually pour in alum water prepared during the fourth cycle, maintaining a "fish-eye boil" (small bubble formation) for 21 days.

4. Stop when the mercury turns faint yellow and becomes malleable under hammering. Continue boiling if insufficient hardness is achieved.

[Seventh Cycle Procedure]

1. Melt the yellowish-brown hardened mercury from the sixth cycle into flat cakes.

2. Soak overnight in a solution of ten liang sal ammoniac, one sheng salt, and three dou water.

3. Simmer with additional mercury for 14 days, then remove and hammer.

4. If too brittle, repeatedly heat the cakes until red-hot, cool by rubbing with ram's horn, then forge until optimal hardness is attained.

Note: Terms like "dragon's blood resin" (dapengsha) and "malachite" (zengqing) refer to specialized minerals in classical alchemy. "One fu period" denotes a full day-night cycle, while "fish-eye boil" describes bubbling at pea-sized intensity. These methods involve toxic substances like mercury—modern replication is strongly discouraged.

This passage describes the eighth and ninth refinement stages of the "Ninefold Cyclically Transformed Elixir" (九转还丹) in Daoist alchemy, along with the elixir's miraculous properties. Here's a modern interpretation:

Eighth Refinement Method:

1. Take the "subdued-fire gold leaf" (specially treated gold foil) from the seventh refinement and heat until glowing red

2. For every liang (about 40g) of gold foil, add one liang of mercury, then grind into a golden paste while hot

3. Divide the paste into finger-sized thin slices and arrange them in the alchemical furnace

4. Add one large liang each of salt, saltpeter, and "Hu Tong resin" (a specific tree resin), mixing and grinding finely

5. Separate the layers with cloth, seal the furnace, and refine with alternating gentle and fierce fire (文武火) for three days and nights

6. After cooling, open the furnace. If all mercury has sublimated, grind the remaining substance with salt

7. Wash with water to remove residual mercury, obtaining purple-colored golden sand

Ninth Refinement Method:

1. Take the golden sand from the eighth refinement, using salt as a base (one jin of golden sand to eight liang of realgar)

2. Seal and refine with alternating gentle and fierce fire until complete sublimation occurs

3. Wash with clean water to remove realgar and salt—the golden sand will sink due to its weight

4. Mix the purified golden sand with honey to form millet-sized pills

5. The elixir now transforms from purple to bright red, called the "Radiant Cyclically Transformed Elixir" (赫然成还丹)

Elixir Effects:

• Consumption dispels hundreds of ailments; long-term use extends lifespan
• Can transmute mercury, lead, and tin into gold
• The scripture describes its effects: "The golden sand enters the five viscera like mist dispersed by wind, circulating through the limbs, making one's complexion glow"

Detoxification Method:

Soak the ninth refinement golden sand in five liang of refined mirabilite (玄明粉) with three sheng of water, then steep in gardenia vinegar for three days to remove toxicity.

Notes:

1. "Cyclically Transformed Elixir" (还丹) refers to substances returning to their primordial state through repeated refinement

2. "Gentle and fierce fire" (文武火) denotes the controlled alternation between low (gentle) and high (fierce) heat

3. The entire process embodies the complex Daoist alchemical philosophy of "nine refinements perfecting the elixir" (九转成丹)

This passage discusses methods and precautions for removing fire toxicity during elixir refinement:

Regarding the control of toxicity in compounded medicinal substances, it mentions that gardenia (a Chinese herb) can absorb "Xuanming Qi" (the Daoist concept of primordial pure energy), thereby calming the medicinal properties.

The specific method for eliminating fire toxicity is: take one sheng of honey and half sheng of clear water, simmer them in a vessel. This requires processing through "three fu periods" (referring to the three hottest periods of summer, here likely indicating prolonged simmering). Then wash the sediment with pure water to obtain the purified substance.

When handling gold sand (metallic minerals used in alchemy), it should be placed in a pouch made of five or six layers of fine silk, then wrapped with multiple layers of silk cloth before being submerged to the bottom of a well. This method prevents any adverse reactions in the medicinal substance.

This content comes from the "Yin-Yang Nine Transformations into Purple Gold Elixir Point-Mutation Method," which describes the process of refining elixirs into purple-gold (considered the highest quality in Daoist alchemy) through nine yin-yang transformations. It particularly emphasizes the crucial steps for removing toxicity from elixirs.
