《金丹賦》

I have heard that life is the root of the Dao (the Way), and only heaven, earth, sun, and moon endure eternally. Teaching is the supreme manifestation of the Dao, establishing instruction through the transformations of nature. The Celestial Worthy of Primordial Beginning (Yuanshi Tianzun, the highest deity in Daoism) suspended a jewel the size of a millet grain, exquisitely expounding profound mysteries; Lord Lao (Laozi) ascended the Jade Gate, propagating the principle of stillness and wuwei (non-action). This is the origin of the name "Golden Elixir" (Jindan).

From Wei Boyang of the Han dynasty, who modeled the "Book of Changes" (Zhouyi) to compose the "Triple Unity" (Cantongqi), to Xu Xun (Xu Jingyang), Ge Hong (Ge Zhichuan), and others during the Jin, Tang, and Song dynasties—all reached the supreme state of the Great Dao of the Golden Elixir. Disciple Ma Lizhao is fortunate to live between heaven and earth, admiring the wondrous Daoist methods. Though the path of wuwei is vast and boundless, one must proceed with caution; yet the gates of myriad wonders are open everywhere, requiring focused observation.

Guided by the sages and inspired by true De (Virtue/Power), I dare to study the profound scriptures. With a will as firm as iron, I carve away my stubborn nature; with a mind as empty and still as ashes, I seek to connect with the spiritual root. Life is fleeting as foam on water or a lamp in the wind, while the Great Dao endures like heaven and earth. Thus, the spirit moves ceaselessly—how can thought not be refined? I wish to express sincerity but lament the lack of proper methods.

Alone in an inn, facing the autumn night's chill breeze, I listen to the cicadas' song all night. Closing the scriptures by a solitary lamp, my melancholy gathers, nearly moved to sorrow by the insects beneath the steps. By chance, I obtained this "Ode to the Golden Elixir" (Jindan Fu), though its author remains unknown. I often recite it to dispel gloom, and each time I finish chanting, I cannot help but clasp my knees, lift my head, and feel profound shame. Yet the essentials of cultivation must not be fabricated, nor principles falsely established—this is the profound admonition of the sages. Though dull-witted, I am deeply devoted, hoping to wander the mysteries and gradually penetrate the true depths. If I have overstepped or erred, I willingly accept punishment. I reverently store this text in a box, awaiting guidance from realized adepts, diligently studying what my heart has grasped, and daring to compose this commentary.

(Here begins the commentary on the opening section of the "Ode to the Golden Elixir")

The word "Fu" (夫) signifies profound contemplation, containing radiance, awaiting spiritual insight—desiring expression yet finding words inadequate. The "Dao" is the origin of emptiness and chaos. Lord Lao said: "There was something formless and perfect before heaven and earth. Silent, empty, standing alone and unchanging, revolving endlessly, it may be called the mother of all under heaven. I do not know its name."

This passage elucidates the origin and operational principles of the Dao (the Way). The Dao emerges from the vast emptiness of the primordial void (Taixu, the initial state of cosmic emptiness), first manifesting as the Primordial Qi (Xiantian Yiqi), which then divides into the dual energies of Yin and Yang. From this division emerge heaven and earth, the cycling of four seasons, and ultimately the transformation and nourishment of all things. Thus, the Dao exists prior to the formation of heaven and earth, serving as the root of all existence.

The Xuangang Lun states: The Dao is the system of emptiness, the foundation of creation, the basis of spiritual intelligence, and the source of heaven and earth. This indicates that all phenomena in the universe—whether living beings with breath, conscious entities, formed objects, or various manifestations—undergo continuous transformation through the movement of Qi, all originating from the Dao.

In the undifferentiated chaos before the cosmos took form, the void was boundless. When emptiness reached its ultimate state, it naturally gave birth to Shen (the most subtle spiritual force in the universe). This divine force, through its movement, transforms into Qi. As Qi differentiates, it forms the phenomena of clarity and turbidity, which then manifest as the physical forms of all things. In truth, clarity and turbidity, phenomena, and forms all arise from emptiness—there is no deliberate creator behind them.

Sages, observing the natural transformations of heaven, earth, and all things, thus declare that all emerges spontaneously as Ziran (self-so). Since one cannot oppose the laws of nature, one should instead align with them. By emulating the dual energies of Yin and Yang (the Two Modes), sages grasp the mysteries of nature, thereby attaining longevity and the highest Daoist achievement of feathery transformation (ascension). This is not achieved through forceful techniques, but through comprehending the most authentic principles of nature, enabling them to endure like heaven, earth, the sun, and the moon, eternally maintaining their natural state. Any attempt to forcibly alter this would yield the opposite result. Therefore, humans emulate earth, earth emulates heaven, heaven emulates the Dao, and the Dao emulates Ziran.

Regarding the authenticity of "techniques" (Shu): Deliberate planning and scheming in the mind is called Shu. When applying techniques, one must first understand the principles of the Great Dao. The Great Dao originates from the emptiness of the void, giving rise to all things. Thus, sages observe the patterns of heaven and earth amidst the undifferentiated chaos, study the movements of the sun, moon, and stars, investigate the principles of seasonal transitions, master the essence of the Five Phases (Wood, Fire, Earth, Metal, Water), correlate them with symbolic animals like the dragon, tiger, turtle, and sparrow, comprehend the cycles of mutual generation and conquest, growth and decline, and understand the transformations of the world through the Bagua (Eight Trigrams) and Jiugong (Nine Palaces), exhaustively exploring the images of mutual generation. Only when learners grasp these patterns of change and their numerical principles can they correctly apply techniques. The distinction between true and false techniques lies in this: true techniques align with natural laws, while false techniques are forceful actions that oppose nature. Since the single Qi transforms into all things, within all things...

This passage explores the relationship between the concepts of "truth and falsehood" and the essence of the Dao. It first clarifies that all things originate from the Dao, and at the level of the Dao itself, there is no distinction between truth and falsehood. The Dao encompasses heaven and earth without appearing vast, permeates dust particles without seeming small—it recognizes no preferences between beauty and ugliness, nor can it be harmed. What people call truth and falsehood are actually distinctions made based on perceived benefits or harms—what brings advantage is deemed "true," while what causes injury is labeled "false."

The text then illustrates this through complementary opposites like heaven-earth, yin-yang, water-fire, cold-heat, day-night, and hardness-softness, demonstrating how truth and falsehood are interdependent like these natural phenomena. Without falsehood there can be no truth, just as there can be no day without night. Deliberately pursuing "truth" while rejecting "falsehood" is as impossible as seeking jade while discarding stone, or desiring height while rejecting depth. Therefore, one must first comprehend the patterns of nature to properly understand the relationship between truth and falsehood.

The second part discusses the principles of alchemical practice. "Following the patterns of the Two Modes" means taking heaven and earth's operations as the standard (the Two Modes referring to heaven and earth). In alchemical practice, one must emulate heaven and earth in establishing the cauldron vessel (alchemical equipment), regulate the firing process according to yin-yang transformations, and circulate primordial qi within the furnace. This resembles calendrical systems—by mastering internal rhythms, one regulates external changes. Authentic Golden Elixir (Jindan) cultivation involves recreating heaven-earth patterns within the alchemical vessel to condense the most refined energy.

Finally, it mentions "taking symbols from the Eight Trigrams (Bagua)," meaning referencing their symbolic meanings. The Yijing states that hexagrams are models suspended for observation. Similarly, alchemy must employ symbolic models like the Bagua to comprehend the changing patterns of heaven, earth, and the myriad things.

This passage explains the symbolic meanings and interrelationships of the Bagua (Eight Trigrams), the ancient Chinese symbols representing natural phenomena. The eight trigrams are Qian, Kan, Gen, Zhen, Xun, Li, Kun, and Dui, each composed of varying combinations of solid (yang) and broken (yin) lines that represent different natural forces and human relationships.

The Qian trigram consists of three solid yang lines, symbolizing heaven, metal, the sovereign, and the father. Positioned in the northwest, it forms the fundamental heaven-earth pairing with Kun. The Kun trigram, composed of three broken yin lines, represents earth, soil, the minister, and the mother. Located in the southwest, it harmonizes with the fire element.

Zhen shows two yin lines above one yang line, embodying thunder, wood, the eldest son, and the Azure Dragon. Situated in the due east, it contrasts with Xun. The Xun trigram displays two yang lines over one yin line, signifying wind, wood, and the eldest daughter. Occupying the southeast, it governs commands and directives.

Kan presents yin lines enclosing a central yang line, representing water, the moon, the Black Tortoise, and the second son. Positioned due north, it marks the winter solstice when yang qi begins stirring underground, forming a complementary pair with Li. The Li trigram has yang lines surrounding a yin core, symbolizing fire, the sun, the Vermilion Bird, and the second daughter. Located due south, it embodies the summer solstice when yin qi descends from heaven at noon.

Gen consists of one yang line above two yin lines, representing mountain, soil, and the youngest son—where all things come to rest. Situated in the northeast, it contrasts with Dui. The Dui trigram shows one yin line beneath two yang lines, symbolizing marsh, metal, the White Tiger, and the youngest daughter. Positioned due west, it indicates the moon's dwelling place.

Qian and Kun are unique as pure yang and pure yin trigrams respectively, representing the cosmic poles. Xun, Li, and Dui—all containing two yang and one yin lines—symbolize feminine qualities, while Zhen, Kan, and Gen—with two yin and one yang lines—represent masculine aspects. Through their dynamic interactions, these trigrams form the fundamental patterns governing all phenomena between heaven and earth.

This scripture elucidates the principles of Yin-Yang transformation and alchemical practice. Within the interplay of Yin and Yang, the numerically lesser element often plays the dominant role. Consider the Eight Trigrams (Bagua): while the Qian trigram (pure Yang) and Kun trigram (pure Yin) represent absolute states, the Zhen and Gen trigrams each contain two Yin lines with one Yang line, yet the Yang line isn't centrally positioned; similarly, the Xun and Dui trigrams have two Yang lines with one Yin line, but the Yin line doesn't occupy the center. Only when Yin and Yang each hold their proper positions—as in the Kan trigram (single Yang line centered) and Li trigram (single Yin line centered)—can they fully manifest the transformative processes connecting heaven and earth.

When heaven and earth were first divided from primordial chaos, the True Spirit (Zhen Shen) first circulated the single Qi before separating the cosmos. After this division, heaven took its round form and earth its square configuration, with the four seasons, temperature cycles, and the Five Phases (Wood, Fire, Earth, Metal, Water) each assuming their proper places. The sages established Daoism precisely to help humanity comprehend this process of differentiation emerging from undifferentiated chaos. The same principle applies to alchemy: one must emulate the cosmic separation of heaven and earth within the alchemical vessel, distinguishing the symbolic meanings of the Eight Trigrams just as the cosmos was originally divided, thereby completing the alchemical work.

True transformation arises from the intermingling of Yin and Yang. Before their movement begins, they exist in undifferentiated unity; only through circulation does transformation occur. Yang Qi represents celestial energy, which begins stirring from the depths of utmost Yin during midwinter's Zi hour, gradually ascending thereafter. This mirrors the alchemical process where one must capture the initial stirrings of genuine Yang Qi precisely at the moment of deepest Yin cold.

This passage explains the movement patterns of Yin and Yang energies within the alchemical cauldron during the refinement of the Golden Elixir (Jindan, the highest attainment in Daoist cultivation), along with the symbolic design of the cauldron vessel.

Yang energy rises from the east, rotating leftward to generate and transform all things, reaching its peak potency in the southeast. Yin energy (represented by the Kun hexagram) actually begins germinating within extreme Yang. At high noon during midsummer in the celestial realms, Yin and Yang energies subtly and quietly intermingle. As Yin energy gradually grows and descends, it rotates leftward to coalesce in the west, achieving full potency in the northwest.

To understand the formation of the Great Elixir (Golden Elixir) within the cauldron, one must grasp the fundamental operation of Yin and Yang energies within primordial Qi (original vital energy). When true Qi circulates, the Eight Trigrams (Bagua) each follow their inherent patterns without confusion, and the Five Colors (blue, red, yellow, white, black) naturally manifest without disorder. When Yin and Yang energies completely fuse and transformation reaches perfection, the Golden Elixir is achieved.

The cauldron's form and orientation must emulate Qian (Heaven) and Kun (Earth). The "designation" refers to adopting symbolic meanings, arranging positions according to the images of Qian and Kun. The scriptures describe the Qian-Kun cauldron as egg-shaped—its rounded summit resembling Penglai, the immortal mountain, with yolk and white interdependent, requiring complete sealing. During incubation, the yolk remains centered while the white surrounds it; through twenty-four days of maternal warmth, complete life naturally emerges, manifesting the wondrous creativity of "true spontaneity." If the shell cracks and vital Qi dissipates, success becomes difficult.

Another interpretation compares the Qian-Kun cauldron to the human head. Scriptures record "the head resembles Penglai mountain"—the brain being the root of the body's spiritual essence, dwelling place of the Hundred Spirits (various life energies), source of bodily fluids, and residence of the Golden Mud's (elixir essence) soul. The stomach's square shape receives nourishment, while the brain palace remains round and empty, connecting with primordial Qi, its myriad acupoints resembling rising mist. When one's virtue (De) matches Heaven and Earth and aligns with the Great Dao, it's called the "Primordial Mud Ball" (another name for the upper Dantian), the abode of the original spirit beyond physical form.

Regarding directional orientation, one should emulate the north and south poles. The south belongs to Great Yang (Li hexagram), the north to Great Yin (Kan hexagram), corresponding respectively to the key positions of the Mysterious Elixir (original spirit) and True Elixir (primordial Qi). Just as the Kan hexagram (water) represents immersion and Li (fire) represents illumination, cultivators must understand these principles of selection and rejection.

This passage explains the operational principles of Yin and Yang energies (Kan and Li) in alchemical practice. The Kan and Li trigrams (two of the Eight Trigrams/Bagua) interact harmoniously, mirroring the energetic exchange between Heaven and Earth trigrams. In the alchemical process, there is both "gaining" and "releasing" — acquiring favorable energies is called "gaining," while relinquishing unfavorable ones is termed "releasing." This principle is profoundly subtle and cannot be fully conveyed through simple words. One must thoroughly comprehend the intricacies of the Kan and Li trigrams and understand the mysteries of the alchemical cauldron (referring to either the human body or the physical furnace) to truly master this esoteric mechanism of selection.

When the alchemical firing process reaches mid-spring (the second lunar month), it corresponds to the celestial movement of the Di and Fang constellations (part of the Azure Dragon's seven mansions among the Twenty-Eight Lunar Lodges). At this time, the vital Qi (vital energy) within the alchemical cauldron is at its peak, resonating with the vibrant green energy of the East. Wei Boyang, the renowned Eastern Han alchemist, wrote in the Zhouyi Cantongqi (The Kinship of the Three): "When the Azure Dragon resides in the Fang constellation, spring's vitality stirs the East" — precisely describing this seasonal energetic phenomenon.

The text then discusses the relationship between the southern constellation Yi (one of the Vermilion Bird's seven mansions) and the "White Horse" elixir. "White Horse" refers to the name of the initial-grade elixir. The Huainanzi (Western Han Daoist classic) states that the white horse's teeth symbolize superior cinnabar — white representing western Metal energy, the horse being a southern fire creature, and teeth embodying the elixir's essence. Here, the celestial phenomena of Di, Fang, and Yi constellations connect the Azure Dragon's energy with southern fire creatures and western Metal energy. When the alchemical firing reaches this stage, the initial-grade elixir can be successfully refined.

The passage particularly emphasizes the importance of "consolidating Qian and Kun." Here, "Qian and Kun" metaphorically represent the alchemical vessel (either the furnace or human body). Just as an eggshell must remain intact for incubation, any cracks in the vessel will cause energy leakage. But the deeper meaning is this: while the natural operation of Heaven and Earth requires no artificial reinforcement, failure to follow alchemical principles (the work of consolidation) would lead to cosmic disorder. This seemingly paradoxical statement actually reveals that alchemy requires both alignment with natural laws and meticulous operation.

Finally, the mention of "shedding flesh to attain spiritual freedom" describes how practitioners, through Neidan (internal alchemy) cultivation, gradually transcend physical constraints to reach a state of luminous spiritual clarity. "Freedom" here describes the mind's pristine, untainted state, as clear as purified water. This represents the ultimate goal of alchemical practice — the transcendent state of body and mind.

This passage expounds the fundamental principles of cultivating the Golden Elixir (Jindan) path. Among the Five Phases (Wood, Fire, Earth, Metal, Water), Metal corresponds to bones, Wood to breath, Water to blood, Fire to heart-mind (Shen), and Earth to flesh. The true path to immortality lies in having the heart-mind (represented by the Li Palace, referring to the heart) govern the Five Phases, unifying them under one sovereign. Mercury (referring to primordial essence, Yuanjing) is most crucial—other impurities are unworthy companions. The formation of the Golden Elixir follows the mutual generation of the Five Phases: Water transforms into Wood, Wood into Fire, Fire into Earth, and Earth begets Metal. When Metal Qi is generated, one sheds the mortal body and attains an indestructible vajra-like form.

The origin of human life lies in the union of Yin and Yang Qi. Yang essence transforms into Shen (spirit) and Hun (ethereal soul), while Yin Po (corporeal soul) becomes the corpse and Po. At birth, Yin and Yang are balanced, but as one grows, they wax and wane: when Yang Qi flourishes, Yin Qi declines, bringing life; when Yin Qi flourishes, Yang Qi declines, leading to death. All things exist through Yin-Yang, Hun, and Po, but most perish quickly due to mutual conflict. Only heaven, earth, the sun, and moon endure because their Yin and Yang harmonize without overcoming each other. Thus, sages emulate heaven and earth by refining the Golden Elixir to balance Yin-Yang, Hun, and Po.

Ingesting the Golden Elixir leads to a state of purity and simplicity. "Purity" means essence without impurities, "simplicity" means untainted whiteness, and "detachment" means clarity without flavor. At this stage, Yin and Yang are balanced within, Hun and Po are tranquil, the five viscera are harmonized, the body becomes as solid as metal and stone, impervious to external pathogens, and the mind is serene and desireless. Any interference from flavors like sour, sweet, bitter, or spicy disrupts this equilibrium.

Practitioners should retreat to secluded mountains and deep valleys (qiyan yinhe), far from worldly distractions. Here, "yan" symbolizes towering peaks and "he" represents profound gorges, embodying the transcendent environment for cultivation.

After ingesting the Golden Elixir (Jindan, the supreme alchemical medicine of Daoist cultivation), one's mind becomes serene and desires grow faint. Naturally, one develops aversion toward vulgar worldly matters, preferring instead to dwell in mountain forests and stream valleys, keeping company with immortals.

The phrase "striding across peaks and resting by rivers" describes the spiritual powers attained upon realizing the Dao. Here, "peaks" refer to the Five Sacred Mountains, meaning that after consuming this Golden Elixir, one spontaneously gains the ability to ride clouds and mists, freely traversing the Five Sacred Mountains and great rivers, dwelling at ease across vast waters.

The refinement of the Golden Elixir requires harnessing the "soul of the sun and radiance of the moon" (the essences of solar and lunar energies). The sun corresponds to the Li trigram (one of the Eight Trigrams/Bagua), where "soul" refers to the yin line within Li; the moon corresponds to Kan trigram, with "radiance" denoting the yang line within Kan. Though soul and radiance share the same essence, their manifestations differ: the soul remains concealed within, while radiance shines outwardly. This mirrors how the Li trigram's yang lines appear outside while yin lines stay within, symbolizing how fire appears dark externally yet bright internally. Similarly, mercury appears dark within cinnabar, while silver appears bright within black lead. The classics state that the Book of Changes (Yijing) expounds precisely these principles of sun-moon and Kan-Li dynamics - the golden crow in the sun and jade rabbit in the moon represent this solar soul and lunar radiance. By harnessing these essences to refine the Golden Elixir, practitioners accumulate spiritual power continuously.

Through such cultivation and accumulation, ingesting the Golden Elixir enables "long life and enduring vision" (Daoist longevity techniques), allowing one to traverse vast ages without decline. Just as calculating immense numbers would exhaust all leaves of grass and trees for recording, so too does the Golden Elixir's efficacy enable transcendence beyond natural lifespan limitations.

Golden Elixir cultivation requires awaiting the proper timing of natural creation (zaohua). Here "creation" refers to the operations of Yin-Yang transformation. Refining the Golden Elixir means mastering the patterns of heaven and earth's Yin-Yang movements, achieving the miraculous elixir with perfect precision. The Golden Elixir naturally possesses wondrous transformative powers: summoning winds and rains, riding clouds and mists, moving mountains and draining seas; entering water without drowning, fire without burning; appearing and disappearing at will—even reviving the dead. These transformations stem from the elixir's intrinsic efficacy, not achieved through mere magical techniques, but by seizing the transformative power of cosmic creation itself, awaiting the final achievement of the "returned elixir" (the perfected form of the Golden Elixir).

This scripture elucidates the principles of alchemical cultivation in accordance with natural laws and the crucial balance of Yin-Yang. It first emphasizes that refining the Golden Elixir (Jindan) requires strict adherence to the twenty-four seasonal nodes of the solar year, akin to a charioteer firmly grasping the reins. The primordial Dao (Xiandao) is so fundamental that even Heaven and Earth cannot defy it, while later cultivation must follow celestial rhythms as dutifully as children serving their parents across generations.

Regarding the harmony of Yin-Yang: Yang Qi cannot exist in isolation, nor can Yin Qi dwell alone—their relationship resembles the intertwined serpent and tortoise. The Kan trigram (representing water and the middle son) embodies Yang as the masculine principle, while the Li trigram (symbolizing fire and the middle daughter) represents Yin as the feminine. Although the Qian (Heaven) and Kun (Earth) trigrams each contain three sons and three daughters, the special pairing of Kan and Li is chosen precisely because they occupy the central positions of balanced Yin-Yang interaction. This cosmic union mirrors marital harmony—when their energies intermingle, infinite transformations arise, forming the foundational principle of alchemy.

Upon completing three years of perfected cultivation, the practitioner attains a body of pure Yang, with fully realized spirit (Shen) and soul (Hun), ascending to the Three Pure Realms (Sanqingtian)—the highest celestial domain in Daoism—to become an immortal of the highest order. After ingesting the Golden Elixir, the physical form becomes as immovable as mountains, the consciousness transforms into luminous jewels, and bones turn golden.

The text concludes by affirming that all transcendents who achieved immortality throughout history followed this very path from mundanity to sagehood. Having shed their mortal forms like cicadas, they became "beings beyond the material world"—celestial immortals surpassing earthly constraints.

(Note: The mentioned "Kan, Li, Zhen, Gen, Xun, Dui" refer to the Eight Trigrams (Bagua). "Three Pure Ones" (Sanqing) denotes the supreme triad of deities: Jade Pure (Yuqing), Upper Pure (Shangqing), and Great Pure (Taiqing). "Taiwei" is a celestial realm, while "Tao Gong" likely refers to the renowned alchemist Tao Hongjing.)

There exists a realm that transcends worldly concerns. Ordinary people become entangled in desires arising from external things—when bound by material objects, they fall into the snares of mundane existence. Those who neither pursue external things nor harbor desires remain unattached; this is the state of transcending materiality. As the scriptures say: "Only those who can transcend the world truly possess it; only those who transcend themselves truly preserve themselves." External things can both nourish and destroy the body. Thus, cultivators of truth embrace emptiness, stillness, and self-forgetfulness, using external things to nurture life while avoiding their harms. What wisdom is there in achieving success only to become hopelessly mired in it? This is the realm of those who transcend materiality.

Human nature originates from the truth of the celestial Dao. This "truth" constitutes the guiding principle of the Dao. Master Wu (a Daoist perfected being) said: "Spirit (Shen) derives from the Great Dao—when tranquil, it harmonizes with innate nature; humans receive this spirit—when active, it responds to emotions." Thus, aligning with one's nature consolidates the spirit and preserves celestial truth, while indulging emotions disturbs the spirit and invites perverse Qi. Emotional agitation muddies the spirit; natural serenity clarifies it. Only with clear spirit can one comprehend profound mysteries, attain celestial truth, and allow the spirit to manifest naturally within. This is the meaning of "nature receiving celestial truth."

Maintain the aspiration and Qi of harmonious equilibrium. "Maintaining" means upholding, while "harmonious equilibrium" refers to the balanced Qi between heaven and earth. Heaven's pure Yang Qi shines brightly, while earth's pure Yin Qi remains dark and deep. If pure Yang stays above and pure Yin below, heaven and earth cannot commune, all things fail to grow, and Yin-Yang cannot interact—how then could good and evil be distinguished? When heaven and earth unite, their two Qi blend and steam, generating all things. That which resides precisely between them is harmonious equilibrium Qi—containing the profound meaning of balanced harmony, like the mind of the legendary archer Zhigong. Action resembles drawing a bow: if too high, lower it; if too low, raise it; movement and stillness both follow the middle way. This is the meaning of "maintaining harmonious equilibrium's aspiration and Qi."

Reject the filth of the mundane world. "Reject" means casting aside; "encircling seas" refers to the interconnected land surrounded by oceans; "mud and dust" signify the impure substances upon the earth. Where water meets earth, mud forms; where dry, dust arises. Mud stains objects; dust obscures vision. This filth persists until life's end and should therefore be rejected.

Thus, one seeks the method of immortality. "Method" symbolizes the teaching. Sages establish teachings through symbols. Ancient texts like the Dragon-Tiger Scripture, three volumes of the Golden-Blue Superior Scripture, three volumes of the Purple Sun Golden-Blue Scripture, three volumes of the Golden-Blue Secret Penetration Verses, and three volumes of the Zhouyi Cantongqi (all essential Daoist alchemical classics) expound methods for cultivating immortality.

This passage elucidates the essential principles for cultivating the Great Dao of the Golden Elixir (Jindan). It begins by noting how many ancient Daoist immortals have expounded methods for refining this elixir, whose consumption grants longevity beyond death—hence practitioners constantly seek its life-extending secrets.

Chongxuzi (a Daoist immortal) observes that the path of immortality resembles a crane's flight straight to the clouds, fundamentally distinct from worldly roads. Yet ordinary people often confuse these paths, like pointing toward mountain passes while losing their way—a symptom of their ignorance regarding true immortal-seeking methods.

Genuine Dao-seekers must dedicate themselves to rigorous study, delving deeply into classics like the Cantongqi (a pivotal alchemical scripture) and Jinbi Jing. They must comprehend celestial phenomena while internally harmonizing with the Dao's profound mysteries. By storing subtle principles within their hearts and aligning their spirit (Shen) with cosmic creation, Chongxu Zhenren declares: "Immortals dwell not in distant realms, but within your lucid consciousness." The Treatise on the Attainability of Immortality similarly states: "The Dao isn't remote—it's reached through practice."

Metaphors illustrate this: just as metal and stone contain sound that rings when struck, the human mind must maintain emptiness and stillness to perceive the Dao. When the heart-mind becomes expansive and serene, it connects with the cosmos, revealing celestial mechanisms spontaneously. This constitutes the Golden Elixir's essential method—comprehending mysteries through stillness and attaining resonance through absolute sincerity.

Yanluozi (a Daoist adept) asserts that true cultivators must possess transcendent vision to grasp the profound mysteries of Chongxuan (the Dao's profundity). With radiant integrity, detached serenity, and actions aligned with subtle principles, one eventually perceives heaven-and-earth in one's palm and the six directions within a hair's breadth—discerning all scales of existence and distinguishing truth from falsehood. Only thus can one truly preserve the authentic spirit and nurture the Valley Spirit (the Dao's essence).

The author recounts his decades-long cultivation journey: reverently making offerings to celestial deities, venerating sun and moon, studying authentic scriptures, investigating Yin-Yang's transformative principles, continuously refining subtle teachings, analyzing hidden meanings, and contemplating in stillness. Though complete realization remains elusive, he maintains utmost sincerity in seeking resonance with the Dao and the Golden Elixir's esoteric truths.

Finally, the term "Golden Elixir" is explained: it's so named because gold (symbolizing immortality) is used in its refinement. The Dragon-Tiger Mirror scripture further confirms its correspondence with the Qian hexagram (symbolizing heaven and Yang).

The sun embodies the essence of fire, symbolizing cinnabar (the "dragon" in alchemical materials), while the moon embodies the essence of water, representing lead and silver (the "tiger" in alchemical materials). Cinnabar is the offspring of fire, and mercury the descendant of metal. Gold is nurtured by the sun, and silver nourished by the moon. The sun and moon intermingle, water and fire complement each other, just as the dragon and tiger accompany one another, yin and yang restrain each other, ultimately refining into the Golden Elixir (Jindan). These two treasures (the essences of sun and moon) are the most numinous existences between heaven and earth, and through cultivation, one attains the mystery of the Golden Elixir.

Classics such as the Jinbi Jing, Cantong Qi, Taiyi Zhi, and Riyue Hunyuan Jing all record the profound principles of Golden Elixir cultivation. Only by delving into their subtle and arcane truths can one comprehend their genuine meaning.

The three characters "Dong Xuan Miao" (Profound Mysteries of the Cavern) each hold deep significance: "Dong" signifies unobstructed wisdom and illumination; "Xuan" represents water and fire—water's black hue is called "Xuanming," while fire's crimson hue is termed "Danxuan." The Laojun's verses state: Extract the essence from black metal (lead), take the marrow from red cinnabar; combining these red and black medicines yields the finest results. Red entering black prolongs life, while black entering red leads to immortality. This method of inverting yin and yang is collectively called "Xuan"—black can transform into red, and red can accomplish the Dao of immortality. "Miao" refers to the wondrous transformations of water and fire qi: the essence of water becomes the moon, the essence of fire becomes the sun, cycling endlessly through the void, giving rise to all things—their marvelous functions are boundless. The classics say that only sages truly understand the mystery of water generating all things, and that yin and yang qi, though rootless in origin, contain numinous transformations beyond full comprehension. True scriptures are pearls of wisdom; only those who have attained the Dao through alchemy can compose them—this is the teaching of the sages. The Jinbi Jing, Cantong Qi, and Taiyi Jing are precisely such genuine transmissions of secret knowledge.

From this, we know that within the profound and mysterious lies essential essence. Through studying these classics, we realize that within the obscure, there truly exists subtlety. The Supreme Lord Laozi said: Within the indistinct, there are forms; within the deep darkness, there are substances. That essence is real and can be verified. Water is called "Xuanyao," fire is called "Danming"—"Yao" signifies depth, while "Ming" signifies obscurity. Water's nature is outwardly dark yet inwardly bright and profound, while fire's nature is outwardly bright yet inwardly dark and obscure. The essence lies hidden in the intermingling of water and fire. The Riyue Hunyuan Jing states: The alchemical cauldron symbolizes heaven and earth, the medicines symbolize the sun and moon, and water and fire symbolize yin and yang.

This scripture expounds the fundamental principles and symbolic system of Daoist Neidan (internal alchemy) practice.

Mercury hidden within cinnabar resembles the golden crow within the sun; gold concealed within black lead mirrors the jade rabbit within the moon. By observing the waxing and waning of sun and moon, one comprehends the hidden nature of mercury in cinnabar and silver in black lead. Just as heaven and earth serve as the alchemical cauldron, with sun and moon as the medicinal ingredients, their essences are concealed within celestial movements, invisible to ordinary perception.

"The unified Qi (vital energy) penetrating the Dantian (energy center)" refers to the correspondence between the body's three Dantian (upper, middle, and lower energy centers) and the Three Luminaries (sun, moon, stars) of heaven and earth. True Qi manifests as celestial bodies in the cosmos, as the three Dantian energies in humans, and as lead-mercury-cinnabar minerals in the earth—all being different expressions of the Dao's operation.

The Dao itself is formless and imageless, yet observable through the transformations of water-fire and Yin-Yang. Water's numerical value is one, fire's is two; their union generates three, which then gives birth to all things. Practitioners discern these phenomena to master cultivation methods.

True Qi circulates through the four directions: winter in the north corresponds to the Kan trigram, spring in the east to Zhen, summer in the south to Li, and autumn in the west to Dui. This resembles how potters shape vessels or smiths cast metal—all being works of creation. The mysteries of the Five Phases (Wood, Fire, Earth, Metal, Water) run deep, requiring careful contemplation. Unified Qi divides into Yin-Yang, which generates the Four Symbols (Lesser Yang, Greater Yang, Lesser Yin, Greater Yin), which then transform into the Five Phases. For instance, water-one and metal-four combine to form Wu earth, while fire-two and wood-three create Ji earth—all achieved through regulating the "fire times" (cultivation techniques).

"Stabilizing the solar soul while summoning the lunar spirit" refers to maintaining the stability of yang energy (solar soul) while mobilizing yin energy (lunar spirit)—the foundational method of cultivation. As described in the...

In the cultivation of the Golden Elixir (Jindan), though the hun and po (representing the yin and yang energies within a person) interact like the Golden Crow (the sun) and Jade Rabbit (the moon) inhaling and exhaling in mutual resonance, the practitioner must maintain unwavering stillness of heart-mind (Shen). This is akin to harmonizing with the intrinsic nature of the White Tiger (Western Metal Qi) while simultaneously attuning to the dynamic vitality of the Azure Dragon (Eastern Wood Qi).

To "follow the Tiger's nature" means to align with the contracting, consolidating quality embodied by the Western White Tiger; to "resonate with the Dragon's disposition" signifies merging with the expansive, generative impulse represented by the Eastern Azure Dragon. In Golden Elixir practice, these Dragon-Tiger dynamics correspond to the liver and lungs within the body: the liver, associated with Wood, manifests as the Azure Dragon, while the lungs, linked to Metal, manifest as the White Tiger. One's innate nature (Xing) governs inner stability, like fortifying a city's core; emotional vitality (Qing) governs outward responsiveness, like constructing its protective walls. The Dragon and Tiger's dispositions are ultimately inseparable aspects of a unified whole, not external entities.

The process further employs the Yi Jing (Classic of Changes) to determine optimal timing for cultivation. From the initial emergence of yang at the winter solstice (eleventh lunar month) to the pure yang of the Qian hexagram in the fourth month, then from the first stirrings of yin at the summer solstice (fifth month) to the absolute yin of the Kun hexagram in the tenth month—these mark the natural cycles of solar and lunar movement. Practitioners must emulate the rotation of the Northern Dipper (Ursa Major): in the first month, its handle points to the Yin position (northeast); in the second month, to the Mao position (east), and so on, aligning the furnace-fire's orientation with the twelve earthly branches.

When applying the fire phases (Huohou), regularity must mirror the sun's passage through the twenty-eight lunar mansions. On the third day of the lunar month, the moon appears in the Ji constellation (east); by the fifteenth, its full brilliance reaches the Yi constellation (south). External fire management should be as precise as celestial motion, while internal Qi flow must resemble the uninterrupted exchange between mountain (Gen) and marsh (Dui)—ensuring the unimpeded circulation of yin and yang energies.

This passage explains the principles of coordinating the Five Phases and Eight Trigrams (Bagua) with firing techniques in Daoist Neidan (internal alchemy) practice. In the Bagua system, the Gen trigram (northeast position) corresponds to Earth, while the Dui trigram (due west position) corresponds to Metal. The Dui Metal position also aligns with the earthly branches of Si (巳), You (酉), and Chou (丑) in the temporal cycle.

The Qi of the Metal Phase connects with Gen's absorption of Bing Fire and Dui's absorption of Ding Fire, demonstrating their energetic resonance. The phrase "sowing Virtue (De) and punishment to harmonize hardness and softness" refers to balancing generative forces (represented by De, associated with spring's growth) and restrictive forces (associated with autumn's harvest). Here, "hardness" pertains to Fire and Metal, while "softness" relates to Water and Wood. By regulating the firing process, the vital Qi follows seasonal rhythms—promoting growth in spring and restraint in autumn—thereby harmonizing Water-Fire-Metal-Wood interactions. Only through such seasonal attunement can the Golden Elixir (Jindan) be perfected.

The Central Palace corresponds to Earth of Wu-Ji polarity: Metal-Water belongs to Wu Earth, while Wood-Fire belongs to Ji Earth. The "ninefold reversion of transformations" references the number nine as yang's ultimate (per Yijing numerology: Kan-1, Kun-2, Zhen-3, Xun-4, Center-5, Qian-6, Dui-7, Gen-8, Li-9), with "reversion" indicating celestial circulation. During alchemical practice, the cauldron's Qi follows the sun's motion (one degree daily, five days forming a solar period). All things complete their cycles in ten lunar months, mathematically returning to their primordial state.

"Sevenfold return revealing splendor": Seven corresponds to Dui Metal; "return" signifies cyclical restoration, while "splendor" denotes perfected beauty. The moon begins its journey from western Dui position, moves southward, enters earth in the northeast, and finally returns westward in full luminosity. This mirrors an egg's structure—the firm outer albumen (zhen-stability) embracing the yielding yolk (shun-suppleness)—where gentle incubation nurtures life, embodying outer strength and inner harmony.

Most profound is Water-Fire interaction: The first mystery (yi xuan) lies in primordial Qi generating Water-Fire duality; the deeper mystery (you xuan) manifests when sages emulate celestial patterns to refine the divine elixir. As Fire rotates eastward becoming the Azure Dragon and Water flows westward transforming into the White Tiger, they mirror cosmic motion—where heaven rotates left while sun, moon, and stars revolve right—completing the great Yin-Yang circulation.

This passage elucidates the principles of mutual generation and restraint among the Five Phases in alchemical practice. Cinnabar (a red mineral) symbolizes Fire and occupies the southern Vermilion Bird position; when it rotates eastward, it yields mercury (a liquid metal). Mercury's bluish hue represents Wood and corresponds to the eastern Azure Dragon position. Lead (a black metal) symbolizes Water and resides in the northern Black Tortoise position; when transformed westward, it produces silver. Thus, the saying "Fire turning eastward becomes the Dragon, Water turning westward becomes the Tiger" describes the natural circulation of Qi within the alchemical furnace, mirroring celestial movements.

The ancients taught that the true Dragon doesn't dwell in the Eastern Sea, nor does the true Tiger reside in the West. To rigidly seek them by cardinal directions is like being a sighted man who cannot see. The metaphor of the Tiger shedding its form to bear offspring illustrates metal refinement: just as silver separates from black lead to participate in new reactions, so too does the Dragon riding clouds to spread rain symbolize mercury's distillation from cinnabar, nourishing all things like the Azure Dragon bestows life-giving showers.

Alchemical processes follow Five Phases dynamics: beginning with mercury (white and black) interacting with cinnabar (Fire), all ultimately return to Earth. This mirrors cosmic operation where Water and Fire achieve harmony before returning to balanced neutrality.

The scripture further advises "abandoning the South to take the North": initially progressing from North (Water) to South (Fire), then reversing course. This encodes the shifting dominance between Yin and Yang during alchemical transformation, much like sovereign and minister exchanging roles. The mention of "Jia-Yi ancestral origins" references the cyclical patterns of heavenly stems and earthly branches, emphasizing that alchemy must synchronize with celestial timing.

This passage elucidates core concepts and cultivation methods in Daoist alchemy.

The ten heavenly stems (Jia, Yi, Bing, Ding, Wu, Ji, Geng, Xin, Ren, Gui) hold significance akin to how heaven and earth sustain all beings. In the Qian (Heaven) trigram of the Bagua, the lower three lines correspond to Jia while the upper three to Ren; in the Kun (Earth) trigram, the lower three lines match Yi and the upper three Gui—hence their designation as the "ancestral Jia and Yi."

Water and stone possess both mundane and sacred aspects, just as humans exist in both ordinary and sage states. To transcend the mundane requires relinquishing physical form and abandoning cleverness, making the body like withered wood and the mind like dead ashes—only then can one approach the Dao. Here, water symbolizes mercury while stone represents cinnabar. In their unrefined state they remain ordinary substances, but when processed through alchemical methods within the crucible—mirroring celestial movements and harmonizing Yin-Yang and the Five Phases—they transform into sacred matter.

The "Imperial Son" refers to the Red Emperor's heir from the southern direction, embodying the crown prince destined for imperial succession; the "Dragon Maiden" represents the Red Emperor's daughter. The sovereign symbolizes heaven and earth's governance, with ministers governing north and south (Yin-Yang). As the ancient verse states: one mother births son and daughter—the son becomes Yin's foundation, the daughter Yang's sovereign, with both transforming mutually without losing their origin. The emperor occupies the central earth position, mediating Yin and Yang.

The Dao's essence remains inseparable from heaven (mysterious black) and earth (yellow). Formless and imageless, the Dao manifests as primordial Qi that generates all things. All beings undergo birth and decay between heaven and earth, just as the crucible's authentic Qi transformations follow this cosmic pattern.

Cultivation requires mastering the "guarding the One" and "Three-Five" essentials. The Hunyuan Jing states: Three-Five and One represent heaven-earth's supreme essence—only through Yin-Yang interaction can the Dao emerge. One must discern ruler-minister relationships (referring to primary and secondary alchemical ingredients) and follow Five Phase principles. Without this understanding, the immortal path remains inaccessible. The most essential practice is guarding the One; the most fundamental principle simply concerns the Three Powers of heaven, earth, and humanity.

This scripture elucidates the core principles of Daoist Neidan (internal alchemy) practice, grounded in the mutual generation of the Five Phases (Wood, Fire, Earth, Metal, Water) and the harmonization of Yin-Yang. The opening passage establishes that cultivation fundamentally involves the interaction of the Five Phases, particularly the dynamic equilibrium between water and fire. All methods ultimately return to the root of "One," as described in the Dao De Jing: "The Dao begets One, One begets Two, Two begets Three, and Three begets all things."

The text explains: water represents "One," fire represents "Two," and their fusion through Earth completes the Five Phases. This "One" is actually the formless origin that ascends, descends, and transforms to generate all phenomena. The mnemonic verse states that the Five Phases ultimately return to Earth while containing the "True One" (primordial Qi), which governs all transformations. When practitioners can consolidate their Jing (essence), Qi (vital energy), and Shen (spirit) into this unity, the Dao naturally manifests. Scattered thoughts obscure the True Dao, but with focused concentration, three months of sustained inner observation will cause all spiritual energies to converge, spontaneously producing profound alchemical effects. This singular path to realization requires deep, bone-level comprehension of the sages' wisdom.

"Qingyao" (azure-waisted) refers to mercury, symbolizing water's properties within the Five Phases. Each Phase has distinct characteristics: Wood governs ethereal Qi, Metal governs solidity, while Water and Fire mediate between being and non-being. Mercury's bluish hue associates it with the Wood Qi of the East, representing the beginning of growth that bears fruit by autumn in endless cyclical transformation.

"Xuansu" denotes the Mysterious Origin (primordial Qi) and Pure Whiteness (essential purity), describing the undifferentiated chaos before heaven and earth separated. In alchemical terms, "Qingyao" represents the Dragon (Yang) while "Xuansu" symbolizes the Tiger (Yin). When these two energies circulate—when the Dragon comes to transform the Tiger—practitioners attain profound states.

The phrase "wind regulating seven-eight fire" concerns fire modulation during practice. "Wind" signifies breath, while "seven-eight" symbolizes cyclical changes. The Yijing (Book of Changes) associates the numbers seven and eight with sound above, movement below, and containment within, corresponding to the moon's twenty-four seasonal nodes. Each fifteen-day lunar phase constitutes one Qi: the first quarter moon on day eight manifests one image, reaching fullness on day fifteen as the Qi's peak—totaling eighteen days. Here, "fire" refers to the precise regulation of internal alchemical processes.

This scripture elucidates the principles of Yin-Yang transformation during the alchemical process. The key to successful alchemy lies in mastering fire regulation—proper application yields the elixir, while improper control leads to failure.

The text employs the formation of ice as a metaphor for neidan (internal alchemy): Though ice is fundamentally water, during midsummer (the height of yang) within the Li Palace (southern fire position), a subtle yin energy begins to emerge. As time progresses, this yin energy accumulates until winter, when it condenses into ice as hard as metal. Here, "nine" represents the numerical symbol of the Li Palace, while "six" denotes water's completion number, illustrating how ice develops from faint yin energy within the fire position.

Alchemy requires the harmonious balance of firmness and pliancy, of Yin and Yang. All things manifest firmness in yin positions and pliancy in yang positions. During the alchemical process, external yang firmness conceals internal yin pliancy—or surface yang correspondence masking inner yin correspondence—both representing Yin-Yang harmonization.

When the Azure Dragon (eastern wood symbol) leaps, the White Tiger (western metal symbol) retreats; as the Vermilion Bird (southern fire symbol) ascends, the Dark Warrior (northern water symbol) descends. These movements of the Four Symbols (four celestial creatures) demonstrate mutual Yin-Yang restraint: The yang-affined Azure Dragon and Vermilion Bird naturally rise, while the yin-aligned White Tiger and Dark Warrior naturally sink. Only through this mutual containment can the Golden Elixir be perfected. Just as solar essence ascends and lunar essence descends, their reciprocal restraint prevents dissipation.

The "Golden Crow" (three-legged sun raven) represents mercury (yang essence) within cinnabar, while the "Jade Rabbit" (lunar hare) symbolizes silver (yin essence) within black lead. Though earth generates metal, it cannot match metal's strength—analogous to seasonal alternations between cold and heat (Kan-water and Li-fire). Only through perfect water-fire interaction can the Golden Elixir be achieved.

"Flowing Pearl" and "Charming Maiden" both denote mercury: when within cinnabar it's called Flowing Pearl; after refinement, Charming Maiden. These specialized terms describe how alchemical substances, through furnace processes mirroring solar and lunar cycles, ultimately form "Yellow Sprouts"—the nascent stage of the Golden Elixir.

The alternation of cold and heat, the rotation of Yin and Yang, and the fusion of metal and stone—these constitute the fundamental principles of alchemy.

The dragon (referring to the Original Spirit, Yuanshen) and the tiger (referring to the Original Essence, Yuanjing) exchange breath in mutual nourishment. The scriptures say that the dragon calls the tiger, and the tiger absorbs the dragon’s essence; the two sustain each other and grow together. It is also said that the dragon represents emotion (qing), while the tiger represents nature (xing). The interdependence of emotion and nature embodies the principle of returning to one’s original state (fanben guizhen). This transformation arises from the True Primordial Qi (Zhenyuan zhi qi), cycling endlessly, from which the principle of breath becomes clear.

The hun and po (spiritual energies) also continuously inhale and exhale. When the dragon and tiger exchange breath, the moon releases its Yin po, and the sun absorbs its Yang hun. The South (the Li trigram, associated with fire and symbolizing feminine Yin) and the North (the Kan trigram, associated with water and symbolizing masculine Yang) interact like the union of man and woman. The East (Mao position) and the West (You position) may lie on opposite sides, yet in cultivation, the energy circulates within the cauldron (ding), never straying from the axis of Zi (North) and Wu (South).

This governs the fundamental laws of heaven and earth. The total number of Yang lines in the Qian hexagram is 216, while the total number of Yin lines in the Kun hexagram is 144. When extended, they yield 11,520 possible transformations, encompassing the patterns of all things and perfecting the nature of hardness and softness. The so-called "unrestrained and ever-changing" refers to the Kan and Li hexagrams. Though they are not part of the foundational Qian-Kun structure (hence called "vanished"), they move freely within the six voids (liuxu, the space of the six lines), radiating their essence to illuminate all things.

Just as parents nurture their children, the True Qi (Zhenqi) and mercury (an alchemical term) mutually embrace. Kan and Li are like the framework of a wheel hub: Yin contains Yang to take form, and Yang contains Yin to manifest images. They cycle through the Four Symbols (Sixiang—Lesser Yang, Greater Yang, Lesser Yin, Greater Yin) and interweave the Five Phases (Wuxing). The nurturing process resembles the continuous nourishment of harmonious Yang Qi, all of which relies on the natural cauldron (dinglu) of Qian and Kun (symbolizing the human body or alchemical vessel), where myriad True Primordial Qi (Zhenyuan zhi qi) operate spontaneously.

This scripture elucidates the Daoist alchemical practice that aligns with the cyclical patterns of heaven and earth. The process of elixir refinement mirrors how nature nurtures all things, requiring strict adherence to natural laws. The text mentions "zhu and liang" as ancient weight measurements—sixteen liang make one jin, totaling 384 zhu—used for precisely calculating ingredient proportions in alchemy.

Elixir refinement must synchronize with celestial timing, calculating fire phases in ten-day periods called xun. It also references the transformations of the 64 hexagrams, distributing the 384 zhu weight among alchemical materials. By observing celestial phenomena, practitioners adjust firing techniques to ultimately forge the Golden Elixir (Jindan).

Particular attention must be paid to the solar terms of winter solstice and summer solstice. At winter solstice, Yang qi begins its ascent, dominating from December through April; at summer solstice, Yin qi emerges, prevailing from June through October in an endless cycle. The text details the Yin-Yang transitions from the Qian (Heaven) hexagram to Kun (Earth): beginning with the complete Yang of Qian in April, each month witnesses one changing line until October forms the pure Yin Kun hexagram. Alchemists must follow this rhythm, restarting their fire practice in November.

The narrative then describes Yang qi's rebirth from Kun: after October's Kun formation, November brings the Fu hexagram with its single Yang line, December the Lin hexagram with two Yang lines, January the Tai hexagram with three, progressing until March's Guai hexagram with five Yang lines, ultimately returning to pure Yang Qian. This waxing and waning of Yin and Yang constitutes the celestial pattern that alchemical practice must follow.

This scripture elucidates the correspondence between Yin-Yang transformations in Daoist Neidan (internal alchemy) practice and celestial movements.

From the winter solstice to summer solstice, Yang qi gradually increases, mirroring the progression in the Book of Changes from "the submerged dragon refrains from action" to "the dragon appears in the field." When the sun (Ri Yao, solar brilliance) reaches its celestial zenith, Yang qi naturally arises. The sun represents the sovereign while the moon (Taiyin Yue Yao, lunar brilliance) symbolizes the minister, with the moon's movement manifesting distinct lunar phases.

The moon completes its celestial circuit every 27.5 days, requiring an additional 2.5 days to realign with the sun, thus forming the 30-day lunar cycle. Specifically:

• On the 3rd day, the moon appears in the western Geng position, corresponding to the Zhen trigram, marking the initial stirring of Yang qi;
• On the 8th day, the first quarter moon forms in the southern Ding position, corresponding to the Dui trigram, achieving Yin-Yang equilibrium;
• On the 15th day, the full moon reaches the eastern Jia position, corresponding to the Qian trigram, when Yang qi peaks;
• On the 18th day, the moon enters the Xin position, corresponding to the Xun trigram, as Yin qi begins to emerge;
• On the 23rd day, the last quarter moon forms in the southern Bing position, corresponding to the Gen trigram;
• On the 30th day, the moon disappears in the Yi position, corresponding to the Kun trigram, when Yin qi dominates.

The "golden fluid" refers to the Five Phases process where Earth generates Metal, while the "White Tiger" symbolizes western Metal qi. These transformations all manifest nature's creative work. Practitioners must harmonize their internal Yin-Yang according to these celestial rhythms.

This passage elucidates the principles of Five Phases mutual generation and Yin-Yang transformation in Daoist Neidan (internal alchemy) practice. The text employs symbolic language to describe the interactions of various elements during the elixir refinement process.

The "tiger" here represents "the true metal of unity"—the pure Yang Qi that embodies the white quality of the West. Only in its purest state can miraculous transformations occur naturally. References to specific timings like the "two solstices" (winter and summer solstices) and "two lunar phases" (waxing and waning moons) allude to the rhythmic patterns of genuine Qi transformation within the alchemical cauldron.

The refinement process begins with Kun (Earth) and Gen (Mountain) merging to form the great earth, representing the transformation from emptiness to substance. Then it emulates Qian (Heaven) and Dui (Marsh) to form the celestial dome. The Qi of Zhen (Thunder) first transforms into Dui, then condenses into metal, ultimately forming the Qian heaven. This illustrates the principle of "the eldest son inheriting the father's essence," akin to how the Zhen trigram (eldest son) inherits characteristics from the Kun trigram (mother).

The phrase "flying and anchoring, interlinked" depicts the dynamic interaction between celestial Yang and earthly Yin: heavenly Yang constantly moves ("flying") while earthly Yin remains steadfast ("anchoring"), with both interconnected. The crux of alchemy lies in grasping the "one encompassing three-five" pattern: "one" represents water, "three" signifies the union of water and fire, and "five" denotes earth—the three tightly integrated.

Finally, the text cites discourse about the sun: this supreme Yang essence contains both Yin and Yang (the sun contains the crow, representing Yin essence). Ancient immortals attained pure Yang states by cultivating solar essence. The number "nine" symbolizes the sun and subtly contains the "one encompassing three-five" principle (1+3+5=9). Tao Honggong's verse also notes that "one" as the water number initiates the Five Phases' cyclical movement.

This Ode to the Golden Elixir (Jindan Fu) elucidates the principles and process of refining the Golden Elixir (Jindan, the highest attainment in Daoist cultivation), using the transformations of heaven-earth and yin-yang as metaphors for the profound mysteries of alchemical practice.

It begins by identifying water as the "primordial origin of the Great Mystery" (Taixuan zhi shi, the chaotic state of cosmic inception), the very root of the Dao (the Way). The alchemical process mirrors heaven and earth forging yin and yang, its efficacy rivaling the creative power of nature itself. The Golden Elixir condenses from a mass of primordial qi (vital energy), much like clouds gathering and dispersing. This numinous medicine can transform bones, restoring youth to the aged. A single divine pellet entering the body spreads its medicinal power like wind and clouds, turning white-haired elders back to robust youth and old women into maidens—utterly transmuting physical form to achieve what is called the state of a "Perfected Being" (Zhenren).

Refining the elixir follows the Dao of "punishment and grace" (Xing-De), akin to an emperor governing a nation. Spring governs growth (De), autumn governs austerity (Xing); alchemy too must grasp this rhythm of yin-yang waxing and waning. As Master Li said: when yin and yang harmonize, the hun (ethereal soul) and po (corporeal soul) unite; ruler and minister each keep their proper place, husband and wife are in concord, the sun and moon move in order, and the seasons of cold and heat alternate normally. Only then can the refined Golden Elixir produce its miraculous transformative effects.

"Flying Crimson Summer" (Fei Zhang Zhu Xia) refers to mastering the southern fire phase. "Flying" alludes to the Vermilion Bird (Zhuque, one of the Four Symbols) of the southern Fire Palace, "Zhang" to the lunar lodge Zhang (one of the Twenty-Eight Mansions), and "Crimson Summer" to the season of summer. These are all symbols for controlling the fire during alchemical refinement.

"Subduing in Mid-Spring" (Fu Mao Zhongchun) speaks of restraining锋芒 in the second month of spring (the Mao month). At this time, mercury (a crucial alchemical ingredient) appears bluish, symbolizing the Azure Dragon. Just as spring's governance in nature is lenient, this "dragon" of mercury naturally lies dormant.

"The Appearance of the Nine-Two Dragon" (Fang Jiu’er Jian Long) borrows from the Book of Changes (Yijing), where the second yang line (Nine-Two) of the Qian hexagram states, "The dragon appears in the field." This metaphor describes the initial emergence of yang qi in the cauldron. In the Qian hexagram’s six lines, the upper two represent heaven, the lower two earth, and the middle two humanity. The Nine-Two line, positioned where earth meets the surface, resembles the first stirrings of true yang in the cauldron—capable of generating and transforming all things. The divine elixir’s transmutation follows this same principle.

Finally, "Balancing Two and Eight to Summon the Divine" (Ting Er’ba Zhi Shen) refers to the moment when yin and yang are perfectly balanced (two and eight signify equilibrium), triggering miraculous transformations in the cauldron. "Two-Eight" also subtly hints at the harmonious interaction of Qian (heaven) and Kun (earth)—the most critical juncture in alchemical refinement.

Throughout, the ode employs rich symbolism of heaven-earth and yin-yang to illustrate that refining the elixir must align with natural rhythms and precise timing. Only then can one achieve the Golden Elixir that transcends mortal form.

This passage elucidates several fundamental principles and phenomena encountered during the alchemical process.

First, it explains the correspondence between celestial phenomena and directional orientations: When the sun reaches the first and last quarter moons (the 8th and 23rd days of the lunar month), the southwest corresponds to the Kun position (representing Earth), while the northeast aligns with the Gen position (symbolizing stillness). Within the Five Phases' generative cycle, though Earth lacks fixed form, it attaches beneath the Fire positions (Bing and Ding). The northeastern Gen position possesses the quality of bringing all things to stillness, mirroring the Earth's stable and unmoving nature.

At the critical juncture of alchemical practice, the phenomenon of "the River Chariot soaring aloft" manifests. The "River Chariot" metaphorically represents the vehicle that crosses the river of worldly afflictions, signifying the Golden Elixir (Jindan) has been perfected and can transcend mundane existence. This stage reveals the cyclical manifestation of "white and black" - the "white" symbolizing pure Yang's authentic Qi, while "black" represents the mysterious dark waters of Xuanming. Their alternating appearance demonstrates the practitioner has comprehended the principle of "knowing the white yet guarding the black," with the Golden Elixir's efficacy fully revealed.

During the alchemical process, the continuous firing refines the true gold (Golden Elixir). Though subjected to prolonged smelting through the years, the elixir's divine Qi never diminishes. Just as Earth restrains Water without harming its essential nature, during alchemy the dragon-tiger essences (Yin and Yang energies) submit to the central Earth position of Wuji. Though the Five Phases restrain one another, no actual harm occurs - ingesting such an elixir grants longevity.

Finally, the passage reveals the key to longevity lies in mastering the "mystery and purity" principle: "Xuan" denotes the elixir's mysterious essence, while "Su" represents its pure white substance. The scripture confirms the truth that refining mercury into returned elixir leads to immortality - this teaching is utterly authentic.

This scripture conveys two main teachings:

The first explains the principle of ingesting the Golden Elixir (Jindan, the Daoist alchemical substance believed to confer immortality). Gold possesses indestructible qualities, making it the treasure of all things. When cultivators ingest the Golden Elixir, they extend their lifespan and gradually attain immortal states. Like winter grass that survives when protected but withers when exposed, humans who consume gold become as imperishable as gold itself, while those who consume jade attain its purity. Just as lice darken in black hair, musk deer gain fragrance from eating paulownia leaves, and mercury permeates the body - these phenomena all demonstrate how material properties mutually influence one another.

The second teaching reveals how the ascent and descent of Yin-Yang must rely on the Solar Yang principle. From the eleventh to fourth lunar months, Yang ascends while Yin descends, allowing heaven and earth to unite and all things to flourish. From the fifth to tenth months, the opposite occurs: Yin rises while Yang falls, heaven and earth reverse positions, and all things wither. The sun governs this cosmic process as the sovereign of creation, commanding the transformations of Yin-Yang to nurture life. Even the refinement of divine elixirs and attainment of longevity depend on this supreme power of solar divinity.

The scripture particularly emphasizes the vital importance of the sun and moon. Their radiance illuminates heaven and earth in resplendent colors (symbolizing their manifold energies) and exudes fragrant vitality (describing their abundant power). The hues of the sun, moon, and Five Planets (representing the Five Phases: Metal, Wood, Water, Fire, Earth) shift with the seasons. Since the dawn of creation, these celestial bodies have shone eternally, just as gold never loses its weight. The perpetual existence of heaven, earth, sun and moon stems from their embodiment of Yin-Yang transformation patterns. To refine the divine elixir means to emulate these cosmic operations - fusing the forces of Yin-Yang, sun-moon, dragon-tiger (symbols of Yin-Yang), the four seasons and Five Phases into perfect union, like the celestial phenomena of planetary conjunctions or solar-lunar eclipses, ultimately forging the supreme Golden Elixir.

This scripture elucidates the essential techniques of Neidan (internal alchemy) practice. During cultivation, one's emotions (symbolized as the Dragon) and innate nature (symbolized as the Tiger) must harmonize, while the ethereal soul (represented by the Sun) and corporeal soul (represented by the Moon) alternate in operation. Like the steadfast alchemical furnace (the "Divine Chamber"), it serves both as an external crucible and an internal vessel for mind-nature cultivation. The phrase "mysterious white guarding each other" refers to the interdependent state of Yin and Yang Qi within the body.

In the alchemical process, True Water and True Fire (the body's Yin and Yang energies) are used for refinement. When external fire regulation reaches perfection, the body's water and fire energies circulate like rising mist, eventually condensing into "True Gold" (the Golden Elixir) at specific seasonal nodes. This "gold" does not denote metal but rather the purest energetic essence of the human body.

When the Golden Elixir manifests, it emits vermilion and purple radiance—the hallmark of the Great Elixir's completion. Ancient masters described the elixir's refinement process thus: cinnabar transforms into mercury, mercury reverts to cinnabar, and cinnabar is further refined into the elixir—hence called the "Reverted Elixir" (signifying return to primordial origin). Purple symbolizes gold's return to its source, thus termed the "Great Reverted Elixir."

The crux of cultivation lies in allowing the body's Yin and Yang energies to spontaneously generate and transform within the formless void (profound darkness), mirroring the natural interplay of water and fire between heaven and earth. Ultimately, the perfected Golden Elixir enables practitioners to return to their primordial origin, attaining longevity akin to the cosmos itself.

The Purple River Chariot (a Neidan [internal alchemy] term referring to the pathway of Jing (essence) and Qi circulation within the body) and golden essence are both absorbed into my being. When the essence-Qi transforms into a violet-red hue, it clearly indicates the successful refinement of the Golden Elixir (Jindan). Nowadays, imperial families take pride in wearing vermilion and purple robes, but in truth, these sages were emulating the imagery of the divine elixir.

"To tread freely between heaven and earth while attaining longevity" - here "treading" signifies unimpeded movement. Roaming through the four directions of the cosmos, no boundary seems distant, no wilderness appears vast. The body shares heaven and earth's longevity, while the Dao's methods are as boundless as the Great Void (cosmic origin). The Perfected Master Wei Boyang said: "If there exists one who is pure and detached, whose temperament is harmonious, who avoids worldly strife as one avoids scalding water, who renounces wife and children as easily as removing shoes, who perceives human life as fleeting as a white colt's shadow across a crevice, and who comprehends the eternal nature of the Great Dao - to such a person this scripture may be transmitted." By concentrating on its profound truths and persevering in cultivation without regard for gain or loss, success is assured. Once accomplished, one will view rivers and seas as mere mounds of earth, human existence as froth upon water, capable of ascending beyond the Great Void to wander freely in infinite vastness. This is not the achievement of heaven and earth, but truly the miraculous power of the Returned Elixir (advanced stage of Neidan practice).

These secrets of the Returned Elixir were all personally transmitted by immortals. The essential formulas of Golden Jasper Correspondences (Jinbi Cantong) and the Primordial Chaos of the Supreme Change (Taiyi Hunyuan), mentioned earlier, all contain truth orally transmitted by immortals. Without such transmission, ordinary people could never comprehend them independently. The "Treatise on Mystical Principles" (Xuangang Lun) states: "Those who study immortality must be born with Yang-spiritual Qi (Yangling Qi) - those lacking this innate endowment will never even conceive the aspiration for transcendence. That one devotes heart to the Dao and resolves to seek immortality proves the presence of transcendent bones." The "Treatise on the Attainability of Immortality" (Shenxian Kexue Lun) similarly observes: "One must recognize one's innate destiny, understand the origin of upright Qi, cultivate the mind through emptiness and tranquility, harmonize the body through breath regulation and Daoyin (guiding and stretching exercises), stabilize the Shen (spirit) with sublime teachings of emptiness and stillness, and practice supplementary methods for internal-external cultivation, elevating both form and spirit. Even if one hasn't yet ascended, immortality is assured."

Ingesting the Golden Elixir transforms bones into jade and preserves the form eternally, while maintaining purification practices perfects De (Virtue). This passage describes how after consuming the Great Elixir, tendons become golden and bones turn to jade, with the physical form transmuted to attain longevity. The "Treatise on Manifesting Life" (Zhusheng Lun) states: "If one cultivates the Dao without accumulating De, the Shen will be damaged; if one performs good deeds without cultivating the Dao, one's nature and life cannot endure."

Those who cultivate the Great Dao of the Golden Elixir (Jindan) attain a state where moral virtue (De) and physical refinement reach perfect completion, allowing their essence (Jing), vital energy (Qi), and spirit (Shen) — the Three Primordials — to fully merge into one. This breakthrough transcends the boundaries of life and death, achieving the realm of immortality.

Once an adept ingests the Golden Elixir, they instantaneously shed worldly fetters as effortlessly as discarding worn-out sandals. The power of the Elixir enables one to endure as eternally as Heaven and Earth, with lifespan surpassing even that of celestial cranes and divine tortoises. In this perfected state, practitioners traverse ten thousand miles swift as lightning, yet drift as freely as clouds and mist.

The Perfected Master Tao Hongjing (the Immortal Lord Tao) once declared: "Though Heaven and Earth may perish, my true form remains intact; though all things vanish, my intrinsic nature endures." This metaphor reveals the timeless nature of the Golden Elixir path. As Laozi (the Supreme Venerable Lord) taught: "Seeking it, we find no beginning; following it, we see no end." Thus we perceive the inexhaustible mystery of the Golden Elixir Dao.
