《庚道集》Vol. 3

This scripture reveals the mysteries and efficacy of refining the Numinous Cinnabar Elixir (a type of Waidan, or external alchemy, in Daoist practice). The preface by Yang Qin indicates this is an authentic transmission from a master practitioner.

The Numinous Cinnabar Elixir is refined by gathering the essence of heaven and earth and the energy of the sun and moon. Through fiery refinement, it purges toxic Yin energies. When ingested, it strengthens sinews and bones, replenishes Jing (essence) and marrow, expels the Nine Worms (parasites), and severs the Three Corpses (three harmful spirits residing in the body, according to Daoist belief). It sharpens hearing and vision, reverses aging, and can even revive the dead while extending one’s lifespan. However, achieving this Ninefold-Transmuted Elixir requires sincere and unwavering cultivation—practitioners must not abandon the path midway.

The refining method emphasizes harmonizing Yin-Yang and balancing water and fire. Through the principle of "flying and subduing mother-child interactions" (a technical alchemical term describing the dynamic interplay of medicinal substances) and the gradual nurturing of metals and minerals, the final transformation of the elixir is accomplished. At advanced stages of cultivation, one may "shed the mortal shell and exchange it for a new form" (metamorphosis), attaining the state of "sitting in liberation or standing in death" (the ability to ascend to immortality at will)—this is the fruit of Neidan (internal alchemy) practice.

Waidan refinement focuses on the application of lead and mercury (primary alchemical ingredients), requiring precise control of fire so they neither dissipate nor scatter. Ordinary people often pursue external elixirs while neglecting inner cultivation, whereas true adepts prioritize inner refinement over external methods. In truth, the proper path lies in cultivating both. The most crucial element remains the use of cinnabar (the core material in alchemy).

The Numinous Cinnabar’s effects are miraculous: it can turn white hair black, and when mixed with breast milk, it can even revert the milk back to blood. This cinnabar does not require rare herbs—its method is simple and practical. By incorporating suitable metallic and mineral substances and applying the technique of bodily warmth incubation, the refinement can be completed swiftly. Ten taels of Numinous Cinnabar can transmute a hundred taels of lead; one pound of it can subdue a hundred pounds of mercury—such is its extraordinary power.

Finally, it is emphasized that this alchemical secret was transmitted from Lord Lao (the deified Laozi) to Master Xu, passed down through generations and recorded in jade texts, stored in divine cabinets. Only sacred mountains and rivers are worthy of preserving it, and only those of lofty virtue are qualified to receive its transmission.

This scripture expounds the lineage and alchemical principles of Lingsha (Spiritual Cinnabar), a product of Daoist external alchemy (Waidan). The tradition traces back to Immortal Ge Xuan (of the Three Kingdoms period), passing through Baopuzi (Ge Hong, the Eastern Jin Daoist theorist), Western Hua Immortal Lü Dongbin, Minister Zhang, Ren Bao, and others, ultimately forming a complete alchemical system.

Mastering this art not only elevates seven generations of ancestors but enables personal ascension to immortality. On a grand scale, it enriches the nation and secures the people; on a personal level, it brings familial prosperity. Yet novices often hesitate upon hearing Lingsha's esoteric formulas, necessitating repeated explanations of its foundational principles.

The refinement process follows sequential stages: first herbal decoctions, then mineral roasting in the Primordial Chaos Cauldron (alchemical furnace), followed by cultivation in the Longevity Vessel (special container). Success manifests as Jade Trees in a Gem Grove (alchemical phenomena) that astonish practitioners and delight celestial immortals. Mercury undergoes complete transformation while lead reveals its true nature, ultimately yielding vermilion gold and silver.

Lingsha's creation mirrors cosmic creation, its efficacy rivaling sagehood cultivation. Its transformative patterns resonate with the Bagua (Eight Trigrams) of the Yijing, while its theoretical foundation aligns with Laozi's Nine-Cycle Elixir method. As the Daodejing states: "What looks invisible we call 'Yi'; what sounds inaudible we call 'Xi'." Though named Spiritual Cinnabar, this divine elixir embodies the same truth as Zhongli Quan's teaching: "One golden elixir pellet secures eternal life."

Countless sages across generations practiced this method, recorded in numerous alchemical scriptures. Lingsha represents the crux of alchemy, the guiding principle of cultivation. Some inquire: If Lingsha is so miraculous, why does it require matrix materials (lead, mercury, etc.) for manifestation? This parallels how sparrows cannot birth phoenixes, nor foxes nurture colts—solitary yin cannot generate, isolated yang cannot grow. Mercury embodies pure yin, lead pure yang. As the Yijing states: "The mutual interplay of yin and yang constitutes the Dao"—precisely this principle.

This scripture primarily discusses the method of refining spiritual cinnabar (a type of elixir in Daoist alchemy) and its cultivation requirements. It first points out that although some people obtain and ingest spiritual cinnabar nowadays, they fail to ascend as immortals and encounter various obstacles during refinement—all due to insufficient cultivation. The text emphasizes that only those with corresponding spiritual attainment can truly master the art of alchemy; otherwise, their efforts are in vain.

Refining spiritual cinnabar requires sincere cultivation and self-cultivation of one's nature and virtue (De). If genuine practitioners master the correct method, why should they worry about failing to attain the Dao (the Way) and immortality? The scripture then details the required medicinal ingredients and refinement procedures. The alchemist must maintain purity of body and mind, burn incense to pray to heaven and earth, and hold the intention to benefit all beings—otherwise, they may easily encounter demonic obstructions. Master Zhang Zhonghe particularly warns: If a cultivator lacks perseverance in practice, they should not attempt alchemy. Only when their merit and practice reach completion can they witness the marvel of the spiritual elixir.

The specific refinement method consists of two steps: First is the stir-frying of spiritual cinnabar. Four taels of sulfur (preferably transparent and impurity-free) must be boiled for a full day in the juice of Tian Gongzi grass. If this herb is unavailable, Dianthus superbus may be substituted. The sulfur is then ground into fine powder and boiled with river water. Separately, one catty of mercury is mixed with one tael each of guanzhong (Dryopteris crassirhizoma) and wubeizi (gallnut), along with 2.5 qian of pine resin, and ground evenly before being soaked in rice vinegar and boiled until thickened. These materials are then placed in a new iron wok—first boiled with ginger juice for half a day and dried—where the sulfur is melted over low heat before adding the mercury. Stir-fry slowly with an iron spoon. The entire process requires precise heat control: no yellow smoke should arise, nor should vinegar be sprinkled. Continuous stir-frying for a full day is necessary until the mixture turns bluish-gold—only then is it successful.

The second part, concerning the construction of the furnace and cauldron, is not recorded in detail. Finally, a poem is appended, using the metaphor of the "charming maiden" (referring to mercury) marrying "Liu Lang" (referring to sulfur) to vividly illustrate the alchemical principle of Yin-Yang harmonization.

The Gengdao Ji (Compendium of Metallurgical Dao) records the method for refining numinous cinnabar, here explained in modern terms:

To refine numinous cinnabar, first grind lapis lazuli (10 liang) and lump cinnabar (1 liang) into extremely fine powder. Begin by mixing premium vinegar with thick ink, applying three to five layers at the bottom of the water cauldron (alchemical vessel) to create a thick base for cinnabar collection. Next, blend clam powder and red halloysite with vinegar, add a small amount of honey to seal the vessel, then secure it tightly with iron wire. Finally, seal the entire setup uniformly with liuyi ni (a specialized Daoist alchemical sealing compound) and yellow lead oxide.

After allowing the sealed vessel to dry completely for one day and night, place it in the furnace with the water cauldron filled to capacity. Begin heating with three jin of charcoal. When the water level drops by one or two cups, replenish with two to three jin of charcoal. Continuously monitor the water level, maintaining three cauldrons' worth of water by periodically adding hot water and charcoal. After five double-hours, increase the fire intensity to five or six jin of charcoal, culminating in a final firing with fifteen jin of fuel. Upon cooling and opening the furnace, properly refined numinous cinnabar should be hard and resonant when struck. Softness or mercury content indicates failure.

Common causes of failure include: incomplete reaction between sulfur and mercury, insufficient calcination of lapis lazuli, omission of rice vinegar, uneven fire control, or inadequate heat intensity. Special attention must be paid to using hot (never cold) water in the water cauldron, and ensuring flames never exceed the vessel's seams.

The scripture states that this lapis-based numinous cinnabar requires fifteen jin of firing, equivalent to nine centuries of concentrated solar essence in nature. White cinnabar corresponds to the Kan trigram (Water), red to the Li trigram (Fire). Through ji ji (perfect balance of water and fire) and the fusion of Metal, Wood, and Earth from the Five Phases, the elixir ultimately congeals. A mnemonic verse summarizes: "When the Five Phases merge in Kan-Li's palace, a crimson elixir forms—yin and yang unite their power, ninety days' work achieved in one morning."

An alternate refining method: Burn green mulberry branches to ash, filter the lye, then add alum (2 liang), realgar (2 qian), Sichuan pepper (1 liang), rock salt (1 liang), and chalcanthite (3 qian)—five medicinal substances. Process these ingredients mixed with the lye and vinegar in a new iron pot or stoneware vessel.

This scripture primarily discusses two alchemical methods: the Huachi Lead-Sulfur Crucible technique and the Gen-Sulfur Crucible technique.

The first method employs black lead (one jin) and sulfur (two liang). Begin by melting purified lead in a clean pot over fire, then gradually add finely ground sulfur to the molten lead while stirring continuously with an iron spoon. When the sulfur begins to dance like fire moths, emitting scattered sparks, remove the pot from the flame and continue stirring until the sparks fade. Return it to the fire and slowly add the remaining sulfur powder until fully incorporated. Once cooled, grind the mixture into fine powder—this is the "Huachi" (Flower Pool). This process symbolizes the fusion of lead and mercury (representing Yin and Yang), the mutual generation of the two energies (Qi), and the harmonious union of Yin and Yang, akin to the balanced circulation of Qi and blood in the human body. Through this refining method, where water and fire complement each other and Yin-Yang achieve harmony, one grasps the principle of attaining immortality.

The second method uses refined sulfur (four liang) and mountain-marsh silver (half a jin). First, hammer the silver into slightly thick foils, then roast them over fire until extremely hot before sprinkling sulfur powder on top. Repeat this roasting until the sulfur turns bluish-black. Layer by layer, continue until the sulfur fully permeates the silver foils, then grind the mixture into powder and combine it with other medicinal ingredients to form the "crucible" (a container or matrix for alchemy). Additional ingredients include hematite (calcined seven times and quenched in vinegar), pyrolusite, and red crowfoot (four liang each), along with four liang of Gen-Sulfur.

These methods exemplify the Daoist alchemical tradition of integrating material transformation with Yin-Yang and Five Phases theory. Through specific refining processes, ordinary substances undergo qualitative changes, serving the ultimate goal of cultivating longevity.

This passage describes specific operational procedures and formulas in Daoist alchemy, focusing on the refinement method of "Lingsha" (a type of alchemical material).

First, three raw materials (such as Gen sulfur and mountain-marsh minerals) are ground into powder and mixed uniformly in specific proportions to form the "kui" (an alchemical container or base material). The Lingsha is then moistened with vinegar paste, coated with mountain-marsh powder, and wrapped tightly in high-quality mountain-marsh foil before being bound securely with cotton thread. The prepared blocks are arranged inside the Gen sulfur kui and covered with additional material. If a specialized "divine chamber" (an alchemical vessel) is unavailable, circular slices of mountain-marsh minerals may be used as a substitute.

The entire apparatus must be tightly secured with iron wire and placed in an ash-filled jar. The firing process follows a precise sequence: initially, a two-tael fire is maintained for two days, after which the heat is gradually increased, with the full refinement cycle lasting seven days. Upon completion, the Lingsha is extracted, and any residual medicinal substances on its surface are removed.

The text further explains the preparation of a "close-wrapping medicine" (a coating for the Lingsha) using ingredients such as chalcanthite and sulfur. After stir-frying, this mixture is applied to the Lingsha’s surface. It is noted that these substances stabilize mercury (liquid metal), preventing its dissipation.

Finally, a poetic verse outlines the key principles of fire regulation in alchemy: the heat must be adjusted at specific celestial hours (such as the Bing Palace or the Mao-You periods), with auxiliary herbs like arisaema and burreed rhizome playing supporting roles. The entire process emphasizes the importance of the "mother kui" (the foundational vessel), believed to ensure the elixir fully absorbs the "mother qi" (the foundational medicinal efficacy).

This scripture describes a Waidan (external alchemy) technique in Daoism involving the refinement of "Chanü" (referring to mercury or cinnabar). The process consists of multiple stages:

First, processed cinnabar (prepared ore) is placed in a specialized container called the "mother crucible," arranged like lotus petals, sealed, and then embedded in an ash pit (an insulating ash bed). On the first day, apply two liang of fire during the mao (dawn) and you (dusk) hours respectively. Increase this by one liang daily until reaching half a jin by the seventh day. After one day of refinement, allow the furnace to cool before opening.

Extract one portion of the elixir, wrap it with one and a half liang of white plum flesh, roast for the duration of a meal, then steep in vinegar. If it turns snow-white and loses weight, this indicates the sulfur has been removed, leaving only mercury—at which point the mother material remains undiminished. Poor results suggest insufficient fire application.

Next, decoct the mother crucible with rice vinegar and alum, wash thoroughly, dry it, then reseal for three more days of refinement with five liang of fire during both morning and evening. The scripture quotes Laozi’s explanation: vinegar washing strengthens the mother material’s potency, just as a weak mother cannot bear healthy offspring.

For adepts with resources, further refinement can be achieved by preparing another crucible with one jin of "mountain-marsh ore" (a specific mineral), repeating the previous method for seven days. This yields more resilient cinnabar with enhanced efficacy—marking the first transcendence stage toward sagehood.

The first-stage method details: Remove the outer layer of the previously refined Lingsha (numinous cinnabar), pulverize it, then wrap it into spheres using Kunlun paper (a special paper). Encase these in a paste made from herba violae (substitutable with golden lamproot), croton seeds, and castor bean flesh. Place them in a large sandbox covered with salt blossoms, pierce holes in the salt, add lead plates, then fill and seal with more salt. Apply five jin of fire overnight. After cooling, the resulting substance will exhibit a silver-ore texture.

The passage concludes with verse:

"Sevenfold refinement of Lingsha unfolds three tiers;

The mystery of black-white (Yin-Yang) transformation

Requires a master’s transmission to comprehend."

This passage describes the "Gengdao Collection" practice in Daoist alchemy, which consists of three main stages:

First Transformation - Initial Refining (Dan Tou):

The process begins by boiling cinnabar (the primary alchemical material) with one liter of rice vinegar, half an ounce of green salt, and three qian of basin saltpeter in a cauldron for one full day. This produces a solid elixir foundation, forming the most basic Dan Tou (elixir head).

Second Transformation - Transcending the Mundane:

Using the previously refined cinnabar as a base, one adds one jin of raw cinnabar for further refinement. The specific method involves boiling pearls in yellow vinegar for a period, then cleansing them with pepper broth before drying. Next, five medicinal substances including calomel and sal ammoniac are ground into fine powder, mixed with honey or vinegar, and used to coat the outer layer of the elixir. This is then placed in the furnace for gentle nurturing (Wen Yang). The resulting elixir has transcended worldly impurities and can serve as material for higher-level elixirs.

Third Transformation - Nurturing True Yang:

The text mentions "capturing and binding the Crimson Dragon Child" - a Daoist technical term referring to controlling one's vital essence (Jing Qi). Though not fully elaborated, this clearly points to advanced alchemical stages.

Administration Method:

The completed elixir must be buried in earth for seven days to remove its fiery toxicity before being formed into pills with honey for consumption.

Fire Regulation Technique:

Detailed instructions are given for seven days of fire intensity (measured in liang units), followed by specific fire distribution on the eighth day according to cardinal directions (east, south, west, north). This represents the meticulous fire control technology characteristic of Daoist alchemy.

Note: The term "kui" refers to alchemical vessels, "Wen Yang" means gentle refinement with mild fire, and "fire regulation" (Huo Hou) denotes precise control of flame intensity and timing - all specialized terminology in Daoist alchemical practice.

This passage describes the concrete operational procedures of Daoist alchemy (Neidan), divided into several key stages:

Regarding furnace preparation, it emphasizes the need for pure Yang substances (the "ninefold pure Yang body") in the refining process. While mercury is precious, without the complement of true Yang Qi, it cannot undergo transformation. The specific method involves boiling one pound of cinnabar with medicinal herbs like Sichuan pepper, aconite, arisaema, and daphne, along with minerals such as halite, chalcanthite, and sal ammoniac in rice vinegar for three days and nights. This is followed by half a day's boiling with knotweed juice, then washing and drying with pepper-infused water.

The cinnabar processing technique involves grinding ink and pouring it into an earthenware cup. The cinnabar is coated with this ink and dried on clean tiles, repeating this process five to seven times. It's then thickly wrapped with "Fa Xin" (a sealing material), using second-stage refined cinnabar as base material to be sealed in a special alchemical vessel (gui) with the treated cinnabar.

The cultivation method begins by placing three to five qian of refined cinnabar discs at the bottom, sprinkling with refined mineral powder (Huachi powder) for sealing, then placing in an ash bed for controlled heating. Successful refinement is indicated by a dark mountain-lake coloration; if reddish hues remain, three more days of heating with three liang of fire is required. This cultivation cycle repeats four times, using one jin of material each cycle.

For practitioners not pursuing the ninefold refined Golden Elixir, second-stage elixir can serve as the "Fountain of Longevity Vessel" to cultivate primary cinnabar, embodying the Daoist principle: "The Dao begets One, One begets Two, Two begets Three, and Three begets all things."

The fourth refinement's "irrigation of yellow sprouts" stage describes how the "wood-essence metal-liquid" (refined cinnabar from previous stages) combined with dan sand (cultivated cinnabar) produces miraculous effects. Quoting the Cantong Qi: "When cinnabar's wood essence obtains metal, they unite." Processed cinnabar blocks are placed in vessels for three days of gentle cultivation with three liang of daily fire, then irrigated with four liang of mercury (filtered through three to four layers of parchment). After seven days of sealed cultivation in the ash bed, the mercury dries without sprouting "buds."

Finally, for those not refining the true elixir, refined cinnabar can serve as cultivation medium for primary cinnabar—a method called "morning planting, evening harvest," denoting its rapid efficacy.

This passage describes the cultivation and application of "mercury sprouts" (a refined product of mercury) in Daoist alchemy (Neidan). The process begins with repeatedly refining mercury through controlled firing, gradually forming crystalline structures called "jade sprouts." Each refining cycle lasts approximately seven days. Through multiple additions of mercury and careful cultivation, the alchemist ultimately obtains a precious substance known as "Divine Talisman White Snow."

When one accumulates sixteen taels (approximately one pound) of these mercury sprouts, further processing is required: First, stir-fry them with rice vinegar and medicinal wine for two hours, then continue stir-frying while spraying with medicinal liquid. Finally, place the mixture in a sealed container to cultivate for twenty-one days until it develops a firm and potent texture. This refined product is called "hardened sprouts," suitable for subsequent alchemical procedures.

The fifth transformation method involves pulverizing cinnabar sprouts (a refined cinnabar product) and letting them rest for fourteen days before adding mercury in specific proportions. The mixture is then fired for forty-nine days. Successful refinement produces exquisite crystalline formations called "Jade Trees in the Qionglin Grove." Taking one qian of this substance and mixing it with one tael of mercury, then sealing and heating it will produce cicada-like chirping sounds. The cessation of these sounds indicates completion.

The sixth transformation combines one tael each of the "three sulfurs" (realgar, orpiment, and sulfur) with "jade snow" (also called jade shoots), grinding them together before placing them in a crucible (gan pot) for refinement alongside subdued niter (processed niter). The entire process emphasizes precise fire control and patient cultivation, with each step requiring strict adherence to specific timing and methods.

The passage details ancient alchemical procedures and precautions, divided into three main sections:

The first section describes the alchemical method: Cover the material with half an ounce of cinnabar, seal the vessel, and calcine it three times with nine jin of fire. After cooling, a crimson-red lump will be obtained. To test its efficacy, melt five liang of the Five Metals (five types of metal) into liquid, then add one qian of powdered Three Yellows (realgar, orpiment, and arsenic yellow). If the mixture turns entirely purple, the alchemical process is successful.

The second section emphasizes ethical requirements for using elixirs: Only those with profound virtue (De) may use them, and they must be employed to aid the impoverished and solitary while cultivating one's nature and life. Greedy or excessive use will immediately invite calamity, requiring utmost vigilance.

The third section records the "Method for Subduing Sal Ammoniac": Seal and calcine half an ounce of sal ammoniac (ammonium chloride) with powdered eggplant for one day, then grind the cooled product into powder. It also mentions the "Seven-Return Reverted Elixir" method: Grind eight liang of sulfur and two liang of mercury until black, add one liang of calcined Three Yellows powder, seal and calcine for seven days. Finally, react these materials with mercury to produce "Purple Geng" (a type of elixir).

The concluding poem summarizes the alchemical achievement: After eight refinements, a pure Yang elixir is obtained. But to reach this state, one must accumulate merit, abstain from greed and anger, and complete three thousand virtuous deeds to attain immortality. For ingestion, the elixir should be formed into phoenix-tree-seed-sized pills using honey.

(Note: The described alchemy involves hazardous substances like heavy metals, now scientifically confirmed as toxic. Do not attempt actual practice.)

This passage describes the preparation method and efficacy of the "Ninefold Cycled Golden Elixir" (Jiuzhuan Jindan) in Daoist alchemy. By taking one pellet of this elixir with flowing water, an alchemist can attain the highest realm of cultivation.

Since ancient times, the refining methods for cinnabar (the primary ingredient in alchemy) have never exceeded these principles. The Golden Elixir achieved through the ninth cycle possesses the miraculous power to revive the dead. As the poem describes: after months of profound refinement, the elixir's wondrous effects naturally manifest. Practitioners need not pursue worldly honors like golden seals and purple ribbons (symbols of high office), for they find ultimate joy amidst the bright moon and gentle breeze.

The Supreme Venerable Sovereign (Taishang Laojun, the highest deity in Daoism) states: by reaching this stage and consuming the Golden Elixir, an ordinary human body transforms into a sacred form, reversing aging to regain youth. The specific method involves: establishing an altar at an elevated blessed land (a qi-gathering site), using a jade-green oil cart (a Daoist ritual instrument), paying homage to true deities, worshiping the Great Dipper, and setting up the elixir cauldron and furnace. When refining the great medicine according to this method, one must first coat the cauldron's interior with mulberry bark juice and clay, then place the medicinal ingredients inside before sealing it with a water basin.

After nurturing the mixture daily with five liang of controlled fire for one hundred days, the elixir is retrieved and buried three feet underground for a year. When asked why burial is necessary, the Supreme Venerable Sovereign explains this removes fire toxicity. After one year, it's suspended in a well for another year, then soaked in flowing water for a third year. When the three-year cycle completes, the substance is ground into powder, mixed with licorice juice to form pellets the size of chicken heads, and warmed in the furnace for seven days.

To test efficacy, chickens or dogs may consume it—over time they transform into phoenixes or dragons. Human ingestion leads to sublime embodiment of form and spirit (xingshen jumiao), enabling daylight ascension. The finished elixir must then be soaked in multiple vats of freshly drawn water, replacing the water whenever it warms.

The text further details the "Yellow Sprout Golden Cauldron Ninefold Method": The first cycle uses ten liang of arsenic divided into thirty packets, with two liang of black lead first melted in a sweet-pot furnace. Arsenic packets are added gradually; after three or four packets, the mixture is poured out and the process repeated until only six liang of golden substance remains. The口诀 (mnemonic verse) states: "Using lead yet not using lead, one must work within the lead; when the time comes to use lead, using lead remains mistaken."

For the second cycle, five liang of cinnabar and five liang of previously refined arsenic are finely ground and mixed in a建盏 (alchemical vessel), covered with two or three qian of dead arsenic, then fired until red-hot while bellows fan the flames to produce molten liquid.

This passage describes specific operational procedures in ancient alchemical practices, primarily focusing on the purification of cinnabar (mercury sulfide) and metal transformation techniques.

The process begins by mixing raw arsenic trioxide with cinnabar and calcining the mixture until the arsenic completely volatilizes. After cooling, the cinnabar is retrieved and further calcined to remove any residual arsenic, then formed into soapberry-sized lumps. These cinnabar lumps are then boiled with various medicinal herbs (including Tribulus terrestris seeds, madder root, Japanese knotweed, euphorbia, pumice, magnetite, and needle iron sand) in a prolonged decoction process. The treated cinnabar is subsequently washed sixty times with boiling water.

The purified cinnabar is then ground into powder to serve as the "matrix" (the foundational substance for alchemical operations). Separate lumps of raw cinnabar are wrapped in gold foil and placed in porcelain containers like lotus seeds, sealed with red halloysite mixed with vinegar, secured with iron wire, and left to dry. These containers are then placed in an ash bed and gently heated (using a "two-ounce fire") for seven days.

The third section details metal transformation methods: Plowshare iron is heated until red-hot, shattered, and layered with cinnabar in a crucible for smelting. The cinnabar floats atop the molten iron, and upon cooling, forms crystalline sheets while the iron transforms into high-quality silver. This process can be repeated three times, though the silver obtained in subsequent cycles appears bluish and harder, requiring remelting with the first batch's silver for quality adjustment.

Finally, the "Method of Transcending the Mundane" is described: Four ounces of refined cinnabar are mixed with eight or four ounces of raw cinnabar, wrapped in gold foil, and heated for seven days. The product is then combined with an equal amount of "mother cinnabar" (likely previously refined material), along with realgar and orpiment for further processing. The resulting silver, called "medicinal silver," was considered a transcendent treasure beyond ordinary metals. The text notes that copper could also be transformed through similar methods.

These operations reflect ancient alchemists' attempts to transmute substances and produce precious metals through chemical processes, involving early metallurgical techniques such as amalgamation and alloy preparation.

This passage records specific operational methods in Daoist alchemy (Waidan), divided into several key stages:

The first method is "Soul-Transfer and Spirit-Union Technique": Take ten taels of medicinal ingredients and place them in a sealed vessel (gui). Refine them with two taels of fire intensity for seven days. If the transformation into gold (geng) isn't achieved, reformulate the mixture. Add three taels of raw cinnabar, one tael each of lump orpiment and realgar, wrap them in gold foil, and refine using the same method for another seven days to obtain five taels of product. Take one tael of this and mix with one qian of processed borax, then form ten pills using yellow wax. Each pill can transmute one tael of mountain-gen (a specific mineral) into gold.

Next comes the "Soul-Restraining-Spirit Technique": If the previous fifteen-tael mixture fails to induce transformation, crush it thoroughly and add five taels of raw cinnabar, two taels each of orpiment and realgar, wrap in gold foil, then refine with three taels of fire intensity for seven days to yield twenty-four taels of product. Take one tael of this and mix with one qian each of processed sal ammoniac and borax to make ten pills. Each pill can convert one tael of mercury into gold.

The "Yang-Refining and Yin-Dissolving Method" follows: Use the twenty-four tael product as foundational material (dantou) to refine the "Minor Cyclic Elixir" in a special chamber. Add a total of ten taels of mercury in three stages, refining with three taels of fire intensity for seven days to produce thirty-four taels of purple-gold elixir. This requires repeated purification with fragrant decoctions. After specific time intervals, form small pills. Consuming these for ten days eliminates intestinal parasites, while hundred-day use wards off calamities—marking the initial stage of immortal cultivation.

Finally, the "Qi-Refining into Spirit" stage involves returning the Minor Cyclic Elixir to the vessel for gentle nurturing, performing purification every seven days. After completing a full cultivation cycle (one zhou nian), practitioners can advance their practice further.

These methods demonstrate the intricate craftsmanship and transformative effects of external alchemy, embodying Daoism's pursuit of longevity and metallic transmutation. The mentioned "Three Corpses" (sanshi) refer to three malevolent spirits within the human body, while "Zhou tian" indicates a complete cultivation cycle.

This scripture describes the miraculous phenomena that appear upon successful elixir refinement and the precautions for consuming the elixir.

When the alchemical practice reaches perfection, the elixir transforms from its original color to white, emitting radiant light resembling halos. Upon retrieving the elixir, the entire chamber becomes filled with divine illumination, protected by celestial spirits. At this stage, one must maintain purification rituals, harbor virtuous thoughts, and perform good deeds to safeguard the elixir. Those who wish to consume it should first accumulate merit through virtuous conduct before ingestion, thereby gaining the ability to traverse the void and attain the status of Earth Immortal (a lower rank of Daoist transcendents).

The ninth stage, "Refining Shen to Merge with the Dao," requires specific firing techniques (using four taels of fire) with weekly purification baths. After three years and one thousand days of cultivation, golden light will emanate upon completion—a sign of success. At this juncture, one must invite accomplished adepts to jointly protect the elixir and establish altars to worship celestial and earthly deities. Neglecting these precautions may invite interference from great demons, causing the elixir to lose potency and rendering all efforts futile.

A successfully refined elixir turns golden yellow, symbolizing the return to primordial authenticity—just as the process began with Yellow Sprouts (initial alchemical substance) and concludes with this golden hue. Grinding the elixir must avoid sunlight, lest it disperse with the solar rays. The elixir should be formed into pills using wood honey. A single pellet scattered over an area can bless a thousand-mile radius, dispelling malignant spirits, ferocious beasts, droughts, and floods. Consuming one pellet enables travel to the Ten Continents and Three Isles (legendary paradises), enrollment in the celestial register, longevity matching heaven and earth, liberation of departed souls, and fulfillment of all wishes.

The scripture further states that chickens consuming it transform into phoenixes, while dogs become dragons—such wondrous transformations defy complete description. Those who hear of this elixir have all accumulated virtue through past lives. Wherever this scripture resides, divine protection follows. Those who disparage it reveal their shallow karmic roots. Worthy seekers of this method should prepare sincere hearts and precious offerings to receive the scripture, which must never be casually transmitted to the unworthy—utmost discretion is required.
