《周易參同契分章通真義》Vol. 3

This scripture recounts how ancient sages attained immortality through cultivating the Golden Elixir (Jindan) path, while lamenting how later generations misunderstood these sacred teachings.

The enlightened sages of antiquity (referring to primordial practitioners like the Three Sovereigns) grasped profound cosmic truths. They cultivated themselves by ingesting the Nine-Cycle Golden Elixir, which filled their bodies with vital essence (Jing) and energy (Qi), strengthened their sinews and bones, warded off pathogenic influences, and preserved righteous energy. Through prolonged accumulation, they achieved the transformation of "shedding the mortal shell" to become immortals. Out of compassion for future seekers, they recorded these methods in scriptures. Yet to protect celestial secrets, they revealed only surface techniques ("showing branches") while concealing the fundamental principles ("roots"), using mineral names as metaphors.

Regrettably, later scholars receiving these classics often grasped only literal meanings, mistaking symbolism for reality—treasuring them as heirlooms without genuine practice. This led officials neglecting governance, farmers abandoning fields, merchants discarding wares, and aspiring cultivators falling into destitution. The author (Wei Boyang) deeply mourned this, hence composing this concise yet systematic scripture, hoping discerning readers might penetrate its true meaning.

The second section explains cultivation must emulate celestial patterns. Heaven and earth operate by supreme laws ("Mystic Channel" denoting the Milky Way), spanning countless miles like this galactic river. When celestial signs grow aberrant (like the River Drum star approaching the Stellar Chronogram constellation), people tremble in awe. Should solar shadows deviate, nine years of calamity ensue. Yet heaven favors life—when rulers observe these portents and reform, disasters may be averted. Here astronomical phenomena metaphorize how cultivation must harmonize with natural rhythms, seizing the pivotal moments (guanjian) of Yin-Yang transformation.

This scripture primarily elucidates the principles of furnace control in Daoist alchemy, using natural phenomena as metaphors for the elixir refinement process. When the firing intensity becomes excessive, it resembles the exhaustion of Yangtze and Huai River waters flowing into the sea, with the cosmic Yin-Yang energies circulating between the Zi-Wu-Yin-Shen temporal nodes (Zi and Wu representing the polar extremes of Yin and Yang, while Yin and Shen symbolize their transitional phases). The alchemical process must follow the movement patterns of the Northern Dipper to seize the precise timing, as meticulously as measuring celestial cycles with a balance scale.

The alchemical cauldron emulates celestial movements, its mysterious transformations resembling the vast flow of rivers. Excessive firing intensity manifests like the three stars of Aquila approaching the Dipper (an ancient omen of upheaval), where metallic substances within the crucible melt under fierce flames, causing dangerous overheating in the chamber. These disturbances stem from inaccurate timing that creates excessive Yang energy, requiring the harmonizing power of central Earth Virtue (Earth in the Five Phases system) to restrain the overactive fire with metal and water elements.

Should the cauldron seal prove imperfect, primordial Qi (vital energy) leaks like the draining waters of great rivers. The Yin-Yang energies circulate between the noon hour (Yang apex) and midnight (Yin nadir), with the Yin hour (3-5am) governing Yang emergence and the Shen hour (3-5pm) controlling Yin development—all water-fire operations must align with the Northern Dipper's celestial indications.

Chapter 81 vividly illustrates the alchemical process through striking metaphors: the furnace resembles a mountain-shaped steamer (Zengshan) with raging flames below. The White Tiger (western metal energy) leads the process forward, producing molten metal solutions, while the Vermilion Bird (southern fire energy) circles above, manifesting iridescent radiance. The medicinal substances struggle within the cauldron like birds trapped in nets, emitting plaintive cries resembling an infant longing for its mother. Within less than half a watch (an ancient time unit), the materials develop fish-scale patterns with shifting five-colored hues. The boiling cauldron produces layered accumulations resembling interlocking dog teeth, eventually forming stalactite-like crystalline structures that stack irregularly within the vessel.

Through the movements of the White Tiger, Vermilion Bird and other Four Symbols (cardinal constellations), this passage describes the chemical transformations of metallic solutions under controlled firing. The furnace configuration of "water above, fire below" (Kan-Li interaction) causes metal energy to form white sands or blue-black solutions when meeting fire. The Vermilion Bird (fire of Bing-Ding) drives the Five Phases energies in cyclical motion, creating polychrome luminosity. Seasonal transitions mirror the water-fire alternations, with cosmic laws constraining the elixir refinement like an inescapable net, making the true mercury (alchemical agent) submit to transformation amidst its mournful cries.

This scripture describes the visual phenomena of material transformations during alchemical practice. When refining the elixir, metallic minerals (gold-water) undergo various morphological changes within the cauldron—sometimes resembling broken feathers, other times like gestating embryos. The cinnabar-mercury (essential alchemical materials) alternately appears and disappears. The fire regulation must be as precise as an ancient water clock, while the materials shift unpredictably like fish scales or animal fur, yet all movements follow discernible patterns.

During material coagulation, the substances interlock like jagged dog teeth; when suspended in emptiness, they hang like stalactites. These forms demonstrate the wondrous transformations of lead-mercury (gold-water), where cinnabar-mercury manifests endless variations, ultimately producing miraculous refined essences. This is the revelation by Master Wei Boyang (the renowned Eastern Han alchemist) concerning the material transformations during elchemical refinement.

When yin-yang harmonize properly, they blend like clear waters merging. The Azure Dragon (eastern wood qi) resides at the sixth degree of the Fang constellation, symbolizing spring's vitality; the White Tiger (western metal qi) dwells at the seventh degree of the Mao constellation, representing autumn's austerity; the Vermilion Bird (southern fire qi) occupies the second degree of the Zhang constellation, embodying midsummer's yang energy. When these three converge in the cauldron, they resemble a family reunion. The foundation of alchemy lies in lead-mercury, yet ultimately evolves into the complete Five Phases (three-five refers to the full elemental cycle). The precise timing of firing days has been thoroughly explained in previous texts.

During refinement, the materials first appear white, gradually turn yellow, and finally manifest reddish-black hues both internally and externally—this constitutes the achievement of the "First Cauldron," with elixir grains the size of millet seeds. This is the work of natural creation, never achieved through false methods. Just as mountain-marsh qi evaporates into clouds and rain, or dry earth crumbles into dust, as extinguished flames become ashes. Like plants yielding yellow dye or indigo producing green, animal hides boiling into glue or fermenting yeast—substances easily transform within their own categories, while dissimilar kinds rarely succeed. This exquisite method, repeatedly verified, can be transmitted for ten thousand generations, as stars follow their courses and rivers return to the sea. Practitioners must contemplate deeply and practice hundreds of times to grasp its mysteries, until sudden divine illumination dawns and the mind becomes radiantly clear.

This passage expounds the core secret of Daoist alchemy—the Golden Elixir Reverted Pill (Jinye Huandan), the highest form of alchemical practice. First, one must understand that the Dao's movement follows inherent patterns, and these mysteries are only revealed to virtuous practitioners.

During the alchemical process, substances within the crucible undergo miraculous transformations: initially appearing white, representing the liquefaction of metallic essence; then turning yellow, called "Yellow Sprout" (Huangya, the precious substance formed in early alchemical stages); finally displaying interwoven crimson and black, symbolizing the harmonious fusion of water-fire Yin-Yang energies within the elixir embryo. The supreme Golden Elixir must be rooted in "golden sand with yellow sprout," as recorded in the Dragon-Tiger Classic: metallic essence forms the outer shell while golden liquid circulates within.

The scripture states that consuming one grain-sized golden pill daily for three years enables daylight ascension. All genuine longevity elixirs must originate from the first crucible's golden sand and yellow sprout—otherwise they belong to heretical paths. Ancient alchemist Li Quan, commenting on the Yin Fu Jing, explained that refining the Reverted Pill requires precise fire regulation (temperature control during alchemy): ninety days for primary refinement followed by ten days of supplemental firing. The key lies in the "Divine Water and Flower Pool" (the essence of alchemy), where golden sand and yellow sprout emerge.

This passage emphasizes that without comprehending the primordial source of Heaven-Earth and Yin-Yang, one cannot grasp the Golden Elixir's truth. During refinement, the crucible's maternal substance (foundational alchemical material) undergoes steaming by Yin-Yang energies, resembling cloud-rain transformations until water-fire forces return to the central earth position. The elixir's colors and forms shift continuously within the embryo, naturally transforming like fermenting wine. Thus, sages refine elixirs by gathering the Dao's primordial energies through Five Phase (Wuxing) interactions—never mere mineral combinations.

The author Wei Boyang (Master Wei) solemnly declares these principles are as evident as orderly stars and rivers flowing seaward. Through repeated study, one naturally awakens to their profundity. As the Daode Jing states: The Dao favors none, yet always responds to sincere virtue.

This passage addresses questions regarding the authorship and composition of the Zhouyi Cantongqi (The Seal of the Unity of the Three). It first refutes a prevalent misconception that the text was jointly written by three authors—Wei Boyang, Xu Congshi, and Chunyu Shutong—with each contributing a section. Through textual analysis, it demonstrates that the entire work was in fact composed solely by Wei Boyang, who, after completing the main three sections, added a supplementary chapter titled Wuxiang Lei (The Five Corresponding Categories) to address omissions.

Regarding the supplementary Wuxiang Lei, the passage explains that while the original three sections of the Cantongqi outlined the broad framework of alchemical practice (Neidan), certain details remained incomplete. Wei Boyang thus revisited and expanded upon the text to ensure a more systematic and thorough exposition of theories such as Yin-Yang, the Five Phases (Wood, Fire, Earth, Metal, Water), and the essential principles of alchemy. Specific correspondences are noted, such as the pairing of the Heavenly Stems (Jia-Yi for Wood, Bing-Ding for Fire, Wu-Ji for Earth, Geng-Xin for Metal, Ren-Gui for Water) with alchemical materials like lead, mercury, gold, and silver.

The concluding section emphasizes how the Zhouyi Cantongqi integrates the principles of the Yijing (Book of Changes), Huang-Lao Daoist thought, and practical alchemy. It asserts that the Daoist theories explored by the Yellow Emperor (Huangdi) and Laozi correspond precisely to the actual operations of alchemy. Though the elements involved—such as metal, wood, and fire—manifest differently, they all adhere to the same fundamental principle. Just as the branches, stems, and leaves of a tree vary in form yet share a common root, so too do the diverse aspects of alchemical practice stem from a unified source.

The cultivation of the Golden Elixir (Neidan, internal alchemy) is akin to the growth of a tree—only with deep and sturdy roots can the branches flourish. True practice requires recognizing the fundamental essence, just as true mercury (zhen gong) must be grounded in true lead (innate primordial Qi). Only then can the fruits of cultivation naturally manifest. These words are utterly truthful, and later practitioners should hold them in deep faith.

Chapter 87 employs the imagery of midwinter to illustrate the proper timing of cultivation fire (huohou): In the depths of winter, plants wither, travelers cease their journeys, and rulers retreat into seclusion. This corresponds to the need in cultivation to harmonize with seasonal rhythms, maintaining silence and inward focus. The movement of the Dao is vast and boundless, while the Supreme Mystery (Taixuan, the cosmic origin) is formless and intangible. To defy the natural order is like a city wall collapsing—it inevitably leads to failure in cultivation. This passage serves as a warning to later generations.

The regulation of fire in cultivation must be as precise as the cycle of the seasons: at times like the unfurling of leaves, at others like the ripening of fruit, and still others like the withering of plants. The stillness of midwinter corresponds to the sealing of the alchemical cauldron (a metaphor for Neidan practice), preventing the leakage of Jing (essence) and Qi. The "ruler in seclusion" refers to the Golden Mother of the Central Palace (the Qi of the Dantian), while "keeping silent" symbolizes the chamber of Dui (the trigram representing the mouth). Within the cauldron, transformations are infinite, and the interplay of metal and water (Yin and Yang Qi) is profoundly mysterious. Wei Boyang (Master Wei) points out that while the Great Dao gives birth to all things, it remains formless. One must harmonize Yin and Yang through proper methods (faxiang), grasp the celestial timing, and draw upon the essence of the sun and moon to achieve wondrous transformations within the inch-wide Dantian. Any misstep will inevitably lead to failure—hence these words of caution for future practitioners.

Chapter 88 is the author’s personal reflection: I, a humble man from the wilds of Kuaiji, dwell in secluded valleys like a withered tree, my heart simple and free from worldly desires. Living in quiet seclusion, indifferent to fame and wealth, I embrace serenity and seek only peace. In my idle hours, I composed this text to elucidate the true meaning of the Three Sages of the Yijing and explore the unifying principle within.

Wei Boyang (Lord Wei) says that he sought no worldly fame or fortune, but devoted himself to cultivating the Dao. In a tranquil and untroubled state, he wrote this classic. He distilled the essential ideas of the three sages Fuxi, King Wen, and Confucius, comparing Heaven and Earth to the furnace and crucible of alchemy, and using the movements and transformations of the two Qi of Yin and Yang to explain the laws of nature. Even Heaven and Earth cannot go against this Great Dao—how much less can humans, ghosts, and spirits? Thus, the spirits have no fixed form, and the principles of change have no fixed pattern. What matters is following the laws that govern the movement and stillness of Yin and Yang.

Chapter Eighty-Nine concerns following the patterns of nature. One should follow the Way of Heaven, allowing the spirit to flourish and its marvelous transformations to reach in all directions, bringing peace to the world. This principle applies through all ages and is as clear and orderly as governing a state. Inward cultivation should emulate the natural way of the Yellow Emperor and Laozi, build up deep De (Virtue/Power), and return to life’s source. That source is actually within one’s own heart; it never lies apart from oneself. Hold fast to the primordial unity of Qi, as a fetus clings to its mother, and one can live long and endure. As for taking elixirs, one must understand the principle of Yin-Yang harmony. Mineral substances such as Wudu realgar—the “Eight Minerals”—can in fact be set aside and left unused.

Chapter Ninety concerns distinguishing the true from the false. Though the elixir ingredients prized by the world come in many varieties, they all in fact arise from the same principle. These words are not ornamental flourishes; they contain the truth. If I were to invent false doctrines, I would only bring blame upon myself. The key teachings revealed in the Cantong qi are concise in wording yet profound in meaning, and later generations should follow them. Those who cultivate the Dao should avoid calamity, withdraw to the mountains and forests, and roam through the Great Void; in the end, they can transform their bodies and become immortals. Even a hundred generations later, they can still ascend through feathered flight. Just as trees wither in drought, their branches and leaves losing their vitality, cultivation of the Dao, too, requires knowing how to judge the moment.

This scripture expounds the essential principles of cultivating Neidan (internal alchemy, the Daoist practice of refining one's Jing, Qi, and Shen). The venerable Wei Boyang (revered as Lord Wei) instructs practitioners that forging the Golden Elixir requires utmost sincerity, for this constitutes the most precious treasure in the world.

The crux of cultivation lies in mastering three elemental forces: the Azure Dragon representing liver-wood Qi (Wood Phase), the White Tiger symbolizing lung-metal Qi (Metal Phase), and the Vermilion Bird embodying heart-fire Qi (Fire Phase). In truth, the authentic Golden Elixir requires only metal and fire elements to complete—the so-called three elements merely represent different manifestations during the alchemical process. Though these terms appear under various names, they ultimately express the same universal principle.

The scripture particularly emphasizes that later practitioners should seek reclusion in sacred mountains and immortal realms, far from worldly distractions. Cultivators must accumulate virtuous deeds (De) until their virtue resonates with heaven and earth, their actions mirror the sun and moon, their daily rhythms harmonize with the four seasons, and their prescience communicates with spirits. One must practice in secrecy without error, as the immortal Yin Changsheng advised: "If no suitable location can be found, refrain from forced cultivation." Guard the mysteries of practice with utmost care, grasping the profound mechanisms of cosmic operation.

Upon achieving the perfected Dao (Dao), practitioners attain the state of "formless embodiment"—their physical form vanishes when seated yet reappears when standing, moving freely through water and fire. Even when encountering the great floods of Emperor Yao's era, the severe droughts of King Tang's reign, or the yang-nine-yin-six cosmic calamities (Daoist cycles of tribulation), they remain unharmed.
