《神仙鍊丹點鑄三元寶照法》

This scripture recounts the story of a scholar named Gui Gengzi who encountered an immortal and received secret methods for alchemical mirror-casting:

From childhood, Gui Gengzi studied both literary and martial arts, showing particular interest in esoteric techniques. Around age thirty, while traveling near Mount Song's Shaoshi peak, he rested beneath a great tree and met an elderly man over eighty years old. The elder carried himself with serene dignity, speaking only of Daoist principles for achieving immortality. He invited Gui Gengzi to his secluded dwelling, surrounded by ancient trees and bamboo groves.

Gui Gengzi inquired about legends concerning the Yellow Emperor's ascension to heaven and the iron mirrors supposedly forged by Feng Hou (the Emperor's minister) during the battle against Chi You. The elder countered: "Have you heard of the immortals' method for casting the Three Treasure Mirrors of Heaven, Earth and Humanity through alchemy?" Recognizing Gui Gengzi's sincere devotion and exceptional spiritual bone structure suitable for cultivation, the elder retrieved from his bag a manual written in ancient seal script.

The elder emphasized: "These secret methods were originally intended for virtuous rulers of peaceful reigns. Only when a sovereign's De (Virtue) remains pure and aligned with celestial will during times of great peace may these techniques be employed." Gui Gengzi reverently kowtowed to receive the manual, keeping it closely guarded thereafter. At their parting, the elder prophesied they would meet again in thirty-six years. This extraordinary encounter occurred in spring of the second year of Tianfu era (902 CE) during the Tang dynasty.

The text subsequently details the method for casting the "Heaven-Illuminating Treasure Mirror": One must select a celestial cycle's first Jiazi year (a special Daoist calendrical designation) during the season of peak Yang energy to gather the essential quintessence of five metals for alchemical refinement. A specially oriented furnace must be arranged, with rituals timed according to specific celestial stems and branches (such as the six Wu, six Jia, six Bing, and six Geng combinations) to harness the directional powers of spiritual beings (Azure Dragon, Vermilion Bird, White Tiger). The final product would be a smokeless treasure mirror capable of exorcising malevolent forces.

Note: The "Three Primordials" refer to the triad of Heaven, Earth and Humanity; "Gou Chen" denotes a constellation representing central Earth virtue; terms like "six Wu" and "six Jia" represent stem-branch combinations used in Daoist ritual timing. The entire casting process integrates alchemy (Neidan), astrological knowledge and Five Phases (Wuxing) theory.

The Method of Divine Immortals Refining Elixirs to Cast the Three Primordial Treasure Mirrors – Modern Interpretation:

Method for Casting the Celestial Mirror:

After selecting an auspicious day marked by the Water of Ren (a Daoist calendrical term), construct a three-tiered circular altar from yang earth, standing three feet high. On the altar, place a clay furnace eight feet and one inch tall, with eight gates at its base, each measuring six inches and four fen. Mount an iron celestial wheel atop the furnace and enshrine the Six Jia and Six Ding Divine Generals (Daoist guardian deities), the Solar and Lunar Deities, and the Nine Luminaries (the nine major celestial bodies). At the furnace’s center, refine the Fire Dragon Elixir to cast the Celestial Treasure Mirror—three inches thick, weighing seventy-two jin, with a face thirty-six inches wide. The mirror’s reverse side is inscribed with an inner layer depicting the Purple Tenuity Star Lord (the North Star deity) and an outer ring arranged with the Twenty-Eight Lunar Mansions. In times of planetary anomalies, comet appearances, or extreme weather, fasting and ritual purification are required before activating the mirror, which strengthens righteous Qi (vital energy) and dispels calamities.

Method for Casting the Earth Mirror:

The Earth Mirror shares the same dimensions—three inches thick, seventy-two jin in weight, and thirty-six inches wide. Its reverse side is engraved with the Five Sacred Mountains, rivers and seas, the Bagua (Eight Trigrams) and Nine Provinces, along with sixteen Earth Deities (local land spirits). Casting must occur under a full moon. During earthquakes, landslides, locust plagues, crop failures, or transportation disruptions, devoutly activating the Earth Mirror while cultivating one’s De (virtue/power) will naturally dissolve misfortunes.

Method for Casting the Human Mirror:

The Human Mirror matches the specifications of the other two. Its reverse side bears the Big Dipper, the names of the Sixty Jiazi Deities, imperial titles, personal guardian deities, as well as dragon-tiger motifs, the state’s name, astrological divisions, and administrative regions. It must be cast at high noon on a Bing-Wu day. In times of war or epidemics, activating the mirror with offerings can pacify disasters. During solar terms marking the transition of Yin-Yang, displaying the Human Mirror in the main hall subdues treacherous officials. If the mirror emits light without cause, it foretells rebellion and ensures the submission of all quarters.

Method for Refining Elixirs to Transform the Five Metals:

The Five Metals (gold, silver, copper, iron, and tin) are natural substances that must be transmuted using the Fire Dragon Elixir, refined in the southern Vermilion Bird position (a Daoist directional correspondence), to attain numinous efficacy. The Fire Dragon Elixir is fundamentally the fusion of the essence of southern fire and the northern waters of Ren-Gui (Yin-Yang and Five Phases terminology).

(Note: The term "mirror" (照) refers to a magically empowered treasure mirror; "two energies" (二气) denote Yin and Yang; and "the Jade Mechanism" (璇玑) signifies the Big Dipper.)

Interpretation of the "Method for Immortals to Refine Elixirs and Cast the Three Primordial Treasure Mirrors"

[Principles of Elixir Refining]

This section explains the fundamental principles of elixir refining: All things between heaven and earth are composed of the Five Phases (Wood, Fire, Earth, Metal, Water), containing five types of energy. Yang Qi ascends to form heaven, while Yin Qi descends to form earth. The essence of elixir refining lies in how medicinal substances take flight when encountering fire, hence termed the "Fire Dragon." During the refining process, the dual energies of Yin and Yang (masculine and feminine) remain undivided, with clear and turbid Qi floating indistinctly. Practitioners must therefore patiently await the opportune moment, understanding how to maintain clarity (knowing whiteness) amidst apparent darkness (guarding blackness), and will naturally receive divine revelation. These mysteries were never recorded in writing by the sages, being transmitted solely through oral instruction and mind-to-mind transmission.

[Specifications for Crafting the Golden Cauldron]

The "Golden Cauldron" is the crucial vessel for elixir refining, symbolizing alignment with heavenly Dao above, correspondence with earthly principles below, and connection with human affairs in between. Its construction must strictly adhere to specifications:

• Dimensions: Height—1 chi 2 cun (~40 cm), inner diameter—1 chi 5 cun (~50 cm)
• Weight: 72 jin (~43 kg)
• Structure: Base thickness—1.5 cun (~5 cm), cauldron legs—2.5 cun (~8 cm) clearance from ground, wall thickness—1 cun (~3 cm), capacity—3.5 sheng (~2.1 liters), depth—6 cun (~20 cm), lid thickness—1 cun (~3 cm), handles—1.5 cun (~5 cm) height

[Ten Defects of Unqualified Cauldrons]

1. Impure metal composition

2. Improper casting timing

3. Uneven thickness

4. Incompletely dried molds

5. Suspended casting (disconnected from earth Qi)

6. Presence of air bubbles or sand holes

7. Internal partitions

8. Cross-grain impurities

9. Metal wrinkling

10. Non-standard dimensions

Any cauldron exhibiting these defects cannot be used for refining high-grade elixirs.

[Construction Method for the Elixir Furnace]

The elixir furnace serves as auxiliary equipment to the cauldron, with primary functions including:

• Shape: Upper section circular (representing heaven), lower section square (representing earth), resembling a lotus platform; lateral view evokes the Five Sacred Mountains
• Structure: Three-tiered altar design with eight gates
• Top: Iron celestial disc engraved with the Nine Stars and Twenty-Eight Lunar Mansions (astronomical patterns)
• Operational principle: Synchronized with the 60-day Jiazi cycle (temporal rhythm), corresponding to stellar movements

[Four Sulfurs Fire-Taming Method]

Elixir refining requires preliminary fire treatment of four minerals:

1. Sulfur

2. Realgar

3. Orpiment

4. Arsenic sulfide

Each weighing 1 jin (~600 g), these four minerals form the elixir's protective "city walls." Specific processing techniques involve separate oral formulas. Additionally, 1 jin (16 liang) of cinnabar is required, corresponding to the celestial cycle's 365.25 degrees and the 720 combinations of heavenly stems and earthly branches—numbers symbolizing cosmic operating principles.

This passage expounds the Daoist alchemical practice of "fire timing" (controlling flame intensity and duration), integrating astronomical calendrics with Yin-Yang and Five Phases theory.

First, it explains the movement patterns of Yin and Yang: The sun moves one degree daily (an ancient astronomical concept), representing pure Yang's rhythm; the moon moves thirteen degrees daily, completing 365 degrees and 25.5 minutes monthly, embodying pure Yin's cyclical pattern. Yang energy converges inward while Yin energy expands outward.

Following this is an alchemical mnemonic verse:

Within the sixty-hour (five-day) cycle, one must grasp the movement of Bing-Ding (Fire phase), adjusting according to Five Phases transformations. When Yang energy waxes, follow celestial timing; when Yin energy wanes, track stellar movements. Typically make adjustments at high noon (Yang's zenith), and when the twenty-eight lunar mansions complete their cycle, the elixir will be perfected.

The concrete fire timing method involves:

Counting from the winter solstice (Yang's initial birth), modulate flame intensity according to the seventy-two climatic periods (ancient division of the year). Daily fire control is precisely measured in "liang" and "zhu" (ancient weight units: 1 liang = 24 zhu).

The text then details specific fire measurements for each solar term from winter solstice to awakening of insects (using names like "Earthworm Coils" and "Elk Sheds Antlers" from the seventy-two periods), categorized into celestial, human, and terrestrial sixty-year cycles. For example:

• "Earthworm Coils" at winter solstice: 5 liang 7.5 zhu
• "Elk Sheds Antlers": 10 liang 15 zhu
• "Wild Geese Head North" during minor cold: 21 liang 6 zhu
• Until "Peach Blossoms Bloom" at awakening of insects: 85 liang

These numerical values correspond to precise flame intensity controls, demonstrating how Daoist alchemy synthesizes astronomical calendrics, Yin-Yang theory, and practical application into a unified system.

This scripture records the "Threefold Treasure Illumination Method" time system from ancient Daoist alchemy, correlating celestial phenomena and seasonal signs with specific weight measurements. Here's a modern explanation of its principles:

The text essentially uses natural phenomena as markers for particular weight units. For example:

• "The partridge's call" corresponds to 10 liang, 7 zhu and a half (ancient weight units) in the 7th nine-day period of the human-origin (renyuan) 60-year cycle.
• "The eagle transforming into a turtledove" matches 95 liang, 1 zhu in the 4th cycle of the earth-origin (diyuan) 60-year period.

The passage systematically documents seasonal changes from the Spring Equinox to the Summer Solstice, with each natural event corresponding to specific temporal segments and weight measurements within the Threefold (heavenly, earthly, and human) 60-year cycles. For instance:

During the Spring Equinox, "the dark birds arrive" aligns with 102 liang, 22 zhu and a half in the 3rd cycle of the heavenly-origin (tianyuan) period.

"Thunder begins to sound" corresponds to 106 liang, 6 zhu in the 9th cycle of the human-origin period.

These records reflect Daoism's unique temporal perspective that integrates natural rhythms with alchemical numerology, using phenological changes to mark critical timing in the alchemical process. The "liang" (tael) and "zhu" (about 0.6 grams) mentioned were minute ancient weight units (1 liang = 24 zhu), employed in alchemy for precise control of medicinal ingredient proportions.

This scripture records the measurement methods in Daoist alchemy related to seasonal nodes and natural phenomena. It primarily details the precise ratios of materials required for alchemical practices during different seasonal periods:

The text employs three distinct temporal calculation systems unique to Daoism - the "Human Era Jiazi," "Earth Era Jiazi," and "Heaven Era Jiazi" - each corresponding to specific seasonal transformations.

Each seasonal node is marked by particular natural phenomena serving as indicators, such as "cicadas beginning their song," "the growth of pinellia plants," "the arrival of warm winds," or "crickets dwelling in walls." These observations demonstrate the Daoist practice of aligning human cultivation with celestial and terrestrial rhythms.

The measurements for alchemical ingredients are meticulously recorded using ancient weight units of "liang" and "zhu" (where 1 liang equals 24 zhu), with exact quantities like "180 liang and 14 zhu," "159 liang and 9 zhu," or "122 liang, 4 and a half zhu." Such precision reflects the scientific rigor underlying Daoist alchemical traditions.

The seasonal progression documented spans from summer to autumn, covering Minor Heat (Xiaoshu), Major Heat (Dashu), Beginning of Autumn (Liqiu), White Dew (Bailu), and Autumn Equinox (Qiufen), with corresponding phenological changes in nature noted for each period.

This passage essentially contains secret alchemical formulas that integrate seasonal transformations with exact material measurements to guide practical elixir preparation. The numerical values likely carry esoteric cultivation significance, though full comprehension of the alchemical methods requires cross-referencing with other scriptures. The text exemplifies how Daoist internal alchemy (Neidan) practitioners sought to harmonize their practice with the cosmic patterns of yin-yang transformation and the Five Phases (Wood, Fire, Earth, Metal, Water) through precise temporal and quantitative correlations.

This scripture describes the "Three Primordial Treasure Illumination Method" (Sanyuan Baozhao Fa) in Daoist alchemy, divided into two parts:

The first part records seasonal phenomena during solar terms (Frost's Descent, Winter's Begins, Minor Snow, Major Snow) and corresponding alchemical measurement units. For example, "Frost's Descent when jackals sacrifice prey" refers to jackals beginning to store food during this solar term, while "18 liang and 10.5 zhu" represents weight measurements used in alchemy (ancient 1 liang = 24 zhu). These numbers likely relate to herbal ratios or fire control in elixir preparation.

The second part, "Sacrificial Method," details post-alchemy procedures: Divide the completed elixir into four portions. Three portions create the "Three Primordial Treasure Illuminations" - Celestial Illumination (heaven offering), Earthly Illumination (earth offering), and Human Illumination (human offering). The remaining portion is further quartered - three parts for sacrifices to heaven, earth, and immortal grottoes, while the final portion can be ingested, said to clarify the spirit (Shen) and prolong life. The current imperial reign year should be engraved on a golden case included in the offerings.

Note: "Three Primordials" (Sanyuan) refers to the triad of heaven-earth-humanity; "Treasure Illumination" (Baozhao) likely denotes a type of Daoist ritual implement or talismanic register (Fulu). This text reflects how Daoist alchemy integrates natural cycles, numerical mysticism, and cultivation rituals.
