《感氣十六轉金丹》

This scripture details the method for refining the "Sixteen-Cycle Golden Elixir" (Shiliu Zhuan Jindan), belonging to the practical guidelines of Daoist external alchemy (Waidan). Here is the simplified interpretation:

Materials Preparation:

1. Base material (sixteen taels of metal ingots, chiseled into sixteen small pieces and hammered until edges are smooth)

2. Mulberry wood (dried and burned to ash, with one peck of ash rinsed in boiling water to extract lye solution)

3. Two herbal ingredients:

• Davallia mariesii (locally called "earth monkey," leaves and skin removed)
• Selaginella tamariscina (locally called "ground centipede," washed and cleaned of soil)

(Two catties each, pounded to extract juice)

Production Steps:

1. Pound the herbs repeatedly eight or nine times to extract one peck of juice. If insufficient, supplement by kneading with additional lye solution.

2. Using a sand pot (approximately three-liter capacity) placed on an iron tripod, fill two-thirds with the lye and herbal juice mixture. Suspend the metal pieces in a small bamboo basket inside the pot, then boil over charcoal fire (carefully controlling heat to prevent overflow).

3. Boil continuously for one day and night (one "fu period"). Throughout this process, continually replenish the lye and herbal juice. If liquid reduces, extract more lye from ash residue, mix with herb pulp, and continue boiling.

4. After boiling, remove the metal pieces and dry them with clean cloth. Place them in a specialized sand container (preferably large-sized from Xinzhou production). Arrange the sixteen metal pieces at the container's base.

5. Seal the container's seams with clam powder (or red halloysite) mixed with vinegar, then let stand for one day and night. The next day, open the container, pour four taels of mercury over the metal pieces, and reseal.

6. Finally, place the sand container atop a water cauldron (porcelain vessel holding three liters of water), filling the cauldron two-thirds with boiling water.

Furnace Specifications:

• Alchemical furnace: approximately 66cm tall, 36cm diameter
• Upper section with two holes (about 2cm diameter)
• Lower section with three coin-sized holes
• Water cauldron should be porcelain matching the sand container's base size

(Note: In Daoist alchemy, "fu period" denotes one full day-night cycle, and "water cauldron" refers to a double-boiler setup. This method involves heavy metal manipulation—modern replication is strongly discouraged.)

This scripture describes the alchemical process of refining the "Sixteen-Cycle Golden Elixir" in Daoist Neidan (internal alchemy), divided into two main sections:

The first section details furnace operation:

1. Line the furnace with paper ash as bedding material

2. Light the fire following prescribed methods—using four taels of fuel divided into three sections

3. When the furnace top glows red without extinguishing, cover it with ash

4. Add fuel during the Mao (5-7am) and You (5-7pm) hours daily for seven days

5. After seven days, open the furnace to observe mercury transforming into white crystalline flakes resembling fish scales (four taels)

6. Repeat this process four times, adding four taels of mercury each cycle. Over seven-day intervals, the mercury successively transforms into:

• Jade-like crystalline formations resembling dog teeth (eight taels)
• Horse-tooth-shaped crystalline structures akin to Langgan jade (twelve taels)
• Crystalline growths resembling jade forests (sixteen taels)
• Final yellow sprout (Huangya) formations (totaling twenty taels)

The second section explains Huangya processing:

1. Extract the Huangya for storage as major elixir material or further refinement

2. Huangya roasting method:

• Grind two qian each of saltpeter, flame saltpeter, alum, and table salt into powder
• Place Huangya in an earthen pot, covering it with the four medicinal powders
• Roast over gentle heat to prevent boiling overflow
• Remove Huangya when sizzling sounds cease

3. Huangya purification ("bathing") method:

• Use seven herbs: purple robe (aconite), golden belt (bletilla/ampelopsis), eucommia, fangji, and Sichuan peppercorns
• Simmer two qian of each herb with Huangya in water
• Final transformation yields red powder

Note: "Huangya" (yellow sprouts) is a technical Neidan term denoting the yellow crystalline substance formed during alchemical processes, considered essential for elixir production. "Mao-You extraction" refers to the alchemical technique of adjusting fire phases at specific celestial hours.

This passage describes the 11th to 13th stages of refining the "Sixteenfold Golden Elixir" (十六转金丹) in Daoist alchemy, detailing specialized operational procedures. Here's a simplified explanation:

11th Transformation - Red Powder Method:

The previously prepared "Yellow Sprouts" (黄芽, a preliminary alchemical material) is ground into fine powder and placed in a sand-clay crucible. Seal the vessel's mouth with clam powder mixed with vinegar, then place it on an iron tripod inside the alchemical furnace. This stage abandons the "water cauldron" method in favor of the "Mao-You fire" (卯酉火, representing dawn and dusk fire regulation symbolizing Yin-Yang alternation). Maintain a daily fire intensity equivalent to four taels (四两火候) for 120 consecutive days. The resulting red powder is poured into a water-filled basin - the floating light powder collected with paper becomes "Red Powder" (红粉) for the next "Window Dust" stage, while the settled white sand can be refined into silver for future "Primordial Chaos" (混沌) preparations.

12th Transformation - Window Dust Method:

The collected red powder is compacted into another sand vessel, similarly sealed with vinegar-mixed clam powder. Using gentle fire (四两文火) with alternating dawn-dusk regulation for another 120 days produces an ultra-fine powder resembling sunlight-filtered dust (明窗尘), hence its name. This material serves as the foundation for cultivating cinnabar in the subsequent Great Elixir refinement.

13th Transformation - Great Elixir Method:

This supreme process requires absolute seclusion - no sounds of poultry/dogs nor presence of women. Half the Window Dust is placed in a sand vessel with ten lumps of cinnabar (totaling six taels; oversized pieces hinder proper coating), then covered with the remaining dust. The seal now uses red halloysite mixed with vinegar. Maintained on the iron tripod with alternating dawn-dusk firing cycles...

(Note: "Mao-You fire" refers to the alchemical practice of regulating fire between mao (卯, 5-7am) and you (酉, 5-7pm) hours, embodying Yin-Yang transition. "Primordial Chaos" denotes a particular alchemical substance.)

This passage describes three advanced elixir preparation methods in Daoist alchemy: the Fourteenth Transformation Purple River Chariot, the Fifteenth Transformation Yellow Chariot (yù), and the Sixteenth Transformation Golden Elixir. I'll explain them in sections:

Regarding the Sixteenth Transformation Golden Elixir:

Cinnabar (four taels) is refined for three hundred days to become the "Great Elixir." After opening the vessel, the crystalline deposits adhering to the inner walls (called "window dust") are collected in a clean container. Six taels of this refined cinnabar are used—four taels continue the Great Elixir refinement while the remaining two are ground into powder. If administered to someone who has just died within seven days (when the hun and po spirits haven't yet dispersed) and whose heart area remains warm, half a qian of this powder mixed with well water can revive them immediately. For corpses where the spirits have already dispersed, it prevents decomposition for a thousand years. For living practitioners, the cinnabar is finely ground with mulberry juice to form pills the size of wutong seeds—taken facing north with well water, these make one immune to all diseases. Prolonged use turns the internal organs golden and extends lifespan. Caution: just half a qian of this elixir can transmute one jin of mercury into silver, so it must be used prudently.

Fourteenth Transformation Purple River Chariot method:

Grind four taels of cinnabar, four taels of realgar, and two taels of raw mercury into peach-blossom-colored powder. Place in a sand container sealed with red halloysite clay mixed with vinegar. Set on an iron tripod and refine for sixty days using controlled fire (four taels of fuel at mao hour [5-7am] and you hour [5-7pm] daily). The resulting purple crystals (Purple River Chariot) can transmute one tael of mercury into a yellow substance when just an earpick's worth is used.

Fifteenth Transformation Yellow Chariot method:

First prepare a half-jin "chaos vessel" (hollow container) from silver treated with previously refined red powder. Layer half the window dust as base, add a mixture of Purple River Chariot and four taels of orpiment, then cover with the remaining window dust. Seal with vinegar-mixed red halloysite, place in a large sand container covered with "white tiger stone" (chalk), and refine for forty-nine days using the same mao-you fire control. A mere earpick's measure of the resulting Yellow Chariot mixed with one tael of mercury in a cup will transform into gold when heated gently.

(Note: "Earpick measure" refers to a tiny scoop's quantity; "mao-you peak fire" indicates precise temporal fire control during specific hours; "chaos" denotes specialized alchemical vessels)

Interpretation of the Sixteen-Cycle Golden Elixir Scripture:

Method for refining sixteen-cycle purple-gold powder:

Take yellow yu (an alchemical ingredient) to transmute mercury into gold, totaling sixteen taels, and fashion it into a "hundun" (chaos vessel, a sealed alchemical container). Grind sixteen or ten taels of yellow yu (the remainder may be used for charity) into fine powder, place it in the golden hundun, and seal the vessel's mouth with red halloysite clay mixed with vinegar. When placing it in the "shahe" (a protective outer container), first lay down half of the "white tiger stone" (an alchemical mineral), position the hundun at the center, then completely cover it with more white tiger stone, similarly sealing the shahe's mouth with vinegar-mixed red halloysite. Place it in the alchemical furnace, applying four taels of fire at mao (5-7 AM) and you (5-7 PM) hours daily for forty-nine days. Upon completion, opening the hundun reveals purple-gold powder capable of transmuting five metals into purple-gold—though practitioners are warned against casual use.

Method for refining the Great Elixir:

After completing the above preparations, select an auspicious mountain site with gathered qi (vital energy) and sheltered winds, ensuring no burial mounds or yin energy within three hundred paces. Prepare an ancient sword and bronze mirror, then construct a three-tiered altar (3.6 chi high, 1 zhang in diameter) with a roofed platform. Bury twenty-four taels of cinnabar at the altar's center to stabilize its energy. Install a stove on the altar containing a cauldron, within which resides the "divine chamber." Before refining, offer prayers to the Three Realms, Ten Directions, enlightened immortals, and local deities to prevent yin spirits from stealing the elixir's qi.

Combine the previously refined golden hundun with another sixteen taels of gold (totaling thirty-two taels) to create a larger vessel using the same method. After adding the purple-gold powder, seal it with vinegar-mixed red halloysite and place it in a specialized shahe. Layer half the white tiger stone at the shahe's base, position the hundun, then cover it completely with more stone, sealing again. Support the setup in the furnace with an iron tripod, applying four taels of fire at mao and you hours daily for ten months. Upon opening, the elixir manifests in five grades (quality corresponds to the practitioner's virtue). An alternative method begins refining at winter solstice, harvesting the elixir exactly one year later.

The first-grade elixir, called "Dragon-Tiger Great Return Elixir," forms at the hundun's apex in purple-gold hue. When consumed by accomplished practitioners, it enables physical and spiritual transformation.

(Note: "Hundun" refers to the sealed alchemical vessel; "shahe" is the protective outer container; "white tiger stone" and "red halloysite" are alchemical minerals requiring further study. Historical alchemy involved toxic heavy metals—modern readers must not attempt recreation.)

This scripture details the classification and effects of refining the "Sixteen-Cycle Golden Elixir" (Shiliu Zhuan Jindan), along with specific methods for its ingestion:

The Golden Elixir is divided into five grades:

1. The supreme grade, called "Divine Talisman White Snow Elixir" (Shenfu Baixue Dan), forms around the alchemical furnace (symbolizing the primordial chaos). Resembling fine jade, consuming this immediately transforms one into a Celestial Immortal (high-ranking transcendent being).

2. The second grade, "Golden Fluid Minor Return Elixir" (Jinye Xiaohuan Dan), appears in violet-gold hues. Those with Neidan (internal alchemy) cultivation can achieve ascension upon ingestion, while ordinary practitioners gain immortality.

3. The third grade "Violet Wandering Elixir" (Ziyou Dan) manifests in purple. Neidan practitioners attain transcendence through it, and commoners extend their lifespan significantly.

4. The fourth grade "Violet Gold Elixir" (Zijin Dan) forms at the furnace's base, with effects identical to the Violet Wandering Elixir.

After completion, the alchemist must examine the cinnabar condensation patterns to determine the elixir's grade. The refined substance is ground finely, mixed with paper mulberry sap, and formed into 49 paulownia-seed-sized pills. The remaining dregs transform into sacred artifacts—these may only be used for charitable healing, never for personal gain.

Ingestion method:

1. Place the 49 pills in a red silk pouch within the alchemical furnace (symbolic golden chaos), then position it in the Elixir Well for 49 days with continuous vigil.

2. Upon completion, first offer 25 pills to sacred mountains, rivers, and various deities (including spirits from one's own practice lineage and local earth gods).

3. Finally, at dawn while facing north, ingest one pill with water from the Elixir Well. If one's accumulated De (Virtue) suffices, a celestial jade summons will appear, enabling daytime ascension—with the possibility of bringing family members.

Crucial reminder:

This elixir transcends mundane existence and must be safeguarded secretly. Celestial laws prohibit its misuse—utmost caution is required. The heavens maintain strict prohibitions against improper application of such divine substances.
