《紫陽真人悟真篇拾遺》

"Supplementary Notes on Ziyang Zhenren's Wuzhen Pian: A Vernacular Interpretation"

This collection of Chan-style poetry by Ziyang Zhenren Zhang Boduo reveals a crucial insight: many Daoist practitioners focus solely on cultivating the Golden Elixir (Neidan) while neglecting mental refinement. Without the "dual cultivation of nature and life" (xingming shuangxiu), one cannot attain the state of unity between self and cosmos, let alone transcend the Three Realms (Desire Realm, Form Realm, and Formless Realm) of samsara. The text references ten types of immortals who, despite achieving longevity through practice, may still fall back into rebirth when their merit is exhausted if they fail to cultivate proper samadhi (Buddhist deep meditation). As Maitreya Bodhisattva's verse in the Diamond Sutra states: "Even after cultivating for countless kalpas, one ultimately labors in vain."

The Wuzhen Pian's teaching unfolds in three stages: first using the path to immortality to attract practitioners; then expanding their horizons with Buddhist wisdom; finally employing the true suchness nature (tathata) to dispel illusions and return to the source of emptiness.

The "Odes to the Nature Ground" section expounds Buddhist truths through poetic gathas:

1. Buddha-nature resembles the shared radiance of countless lamps—neither increased nor diminished by individual flames. While attachment to gain or loss constitutes error, the nature itself remains unaffected.

2. The Tathagata's true body permeates all phenomena. Realizing this unimpeded wisdom reveals the Three Realms as our original abode.

3. Though formless, Buddha-nature manifests according to conditions. Like echoes in a valley, without the valley there would be no resonance.

4. Our faculties of perception (hearing, seeing, awareness, knowing) are fundamentally one. Dividing them into four creates artificial distinctions that obscure the true basis.

5. The path requires no distant search—the present moment suffices. Haloed heads and auspicious clouds beneath feet are mere signs, not ultimate truth.

6. Birth and death are illusory; inner vision surpasses physical sight, direct experience transcends verbal explanation. Without awakening to one's true nature, clinging to words inevitably leads back to cyclic existence.

The text concludes by emphasizing the truth that "the Three Realms are mind-only": all phenomena neither exist apart from mind nor are they identical to it. To perceive phenomena is to perceive the fundamental mind, yet nothing can be possessed.

(Note: This work integrates Daoist internal alchemy with Buddhist mind-nature teachings, reflecting the syncretic Three Teachings harmonization characteristic of Song-Yuan period thought.)

Supplementary Commentary on the Purple Yang True Man's "Awakening to Reality"

Seeing Things, Seeing the Mind

Only when encountering external things can one truly perceive the original mind; without external objects, it is difficult to recognize the mind’s true nature. The genuine original mind pervades the entire universe, yet if one tries to grasp it through conceptual thought, they will only distort the truth. Only by not clinging to distinctions when faced with phenomena can one realize their awakened nature.

The Realm of Perfect Penetration

To awaken to true emptiness (the ultimate reality beyond existence and non-existence) is not to fall into lifeless voidness, but to recognize a luminous, dynamic function. This perfect wisdom is omnipresent—when one realizes that the senses, external phenomena, and consciousness are all illusory, wondrous functioning manifests, indistinguishable from that of a Buddha.

Freedom in Accord with Conditions

All things arise and pass before your eyes—let them move and clamor as they will. Maintain the illuminating awareness and stability of the original mind, and you will remain untainted, like a lotus rising from water yet never wet by it.

The Precious Moon as a Metaphor for the Mind

The bright moon hangs in the sky, shining unobstructed over all lands—this is just like the original mind. Try to gather it, and it will not collect; try to scatter it, and it will not disperse. It is neither before nor after, neither near nor far. Superficially, there may seem to be distinctions of inner and outer, yet in reality, sameness contains difference, and difference contains sameness. Tell me, you who are like a puppet pulled by strings (symbolizing those driven by desires), do you understand this truth?

The Essence of the Heart Sutra

The five aggregates (form, sensation, perception, mental formations, consciousness), the four noble truths (suffering, its origin, cessation, and the path), and the six sense faculties and their objects—all are empty, without any substantial nature. Once deluded thoughts are severed, the tranquil essence naturally reveals itself.

Equality of All Things

Fundamentally, there is no difference between myself and others—it is only the discriminating mind that creates distinctions. Ordinary people divide the world into friends and strangers, but I make no such separation. Beings of land and water share the same essence; distinctions of nobility and baseness are like one’s own hands and feet. If even the "self" is unreal, how much more so is "you"? When notions of self and other dissolve, it is like a bubble returning to the vast ocean.

Reflections on Chan Poetry

The Dharma lineage of the Sixth Patriarch Huineng (of Caoxi) is like a single drop of water branching into a thousand streams, illuminating past and present without obstruction. Yet today’s learners fail to seek the source, mistaking the shallow puddles left by horse hooves (superficial views) for the great ocean. Master Xuedou (a Song Dynasty Chan master) grasped the true essence—his teachings roared like a lion’s thunder, shaking the Dharma drum and striking fear into false views. His verses are profound and compassionate, guiding the lost with every word, their brilliance resonating through the ages. Alas, people chase after external appearances, seeking only the surface of words.

Supplementary Commentary on the Wuzhen Pian by Master Ziyang

On the "True Suchness and Ultimate Reality" (Supreme Truth):

The essence of truth cannot be described in words—it has neither hierarchy nor boundaries, being neither material nor empty. The entire cosmos is like a full, luminous moon, and true enlightenment transcends both speech and silence. When you neither cling to grasping nor to renouncing, and remain unattached to all phenomena, you align with the law of truth. Delusive thoughts must be dissolved, yet if one deliberately pursues the "true," truth itself will recede. Only by transcending the duality of "truth" and "delusion" can one attain an unobstructed, genuine mind. In an instant of awakening, eons of karmic burdens vanish; without forced cultivation, one realizes bodhi (enlightenment), forever liberated from the cycles of birth and death.

On "Precepts, Meditation, and Wisdom" (Three Pillars of Practice):

Precepts, meditation, and wisdom are essential methods of cultivation. Though the Buddha expounded them, the unenlightened still cling to them. Simply put: when both inner mind and outer phenomena are relinquished, and thoughts no longer stir, this is "precepts." When the enlightened nature is perfectly radiant, luminous within and without, this is "meditation." When one responds to all things in accord with conditions, with inexhaustible wondrous function, this is "wisdom." These three are interdependent, each the substance and function of the others. Just as the sun requires light to shine, and light requires shining to be bright, precepts, meditation, and wisdom all arise from the same nature—like brightness and the sun being fundamentally one. When even the concepts of "one" and "three" are abandoned, one attains the purest state.

Verses on "The Mind Itself Is Buddha":

Buddha is the mind, the mind is Buddha—yet clinging to the notion of "mind and Buddha" is still delusion. Only by realizing there is neither Buddha nor mind does one perceive the true Dharmakaya (Buddha’s true body). The Dharmakaya has no fixed form, like a sphere of light encompassing all things. The formless essence is the true essence; the featureless appearance is the ultimate reality. It is neither matter nor emptiness, neither moving nor still, neither coming nor going, neither different nor the same.

This scripture primarily elucidates how practitioners can recognize the inherent truth of their original nature through inner awakening. The core teaching is that every person inherently possesses the perfectly luminous Buddha-nature (one's original nature), as precious as the hidden jewel in a poor man's garment.

Key cultivation principles:

The true path lies not in seeking outwardly, but in recognizing the "mani jewel" (metaphor for Buddha-nature) that one already possesses—this radiant essence can illuminate the entire trichiliocosm. Authentic practice doesn't involve forced striving; one must maintain a state of "non-contamination and non-attachment" (untainted by external phenomena yet free from grasping), where neither good nor evil distinctions create fixation—this constitutes genuine pure cultivation.

Buddha-nature resembles the boundless ocean that embraces all things. By preserving the state of "perfectly luminous samadhi-prajna" (meditative concentration and wisdom both complete and radiant), one remains unconstrained in any circumstance. True awakening doesn't pursue emptiness or form, but transcends such distinctions to realize that the "Dharma-body" (Buddha's true form) is none other than the naturally spontaneous Buddha-nature.

All phenomena are ultimately formless (lacking fixed characteristics), yet within this formlessness dwells the true presence of Buddha-nature. The ultimate stage of cultivation returns to the pure, natural state of an infant—neither deliberately pursuing nor rejecting, but moving in accord with conditions.

The scripture concludes that truly awakened beings speak with the lion's roar (symbolizing authoritative teaching), naturally discerning truth without becoming entangled in concepts of arising and cessation like ordinary people. The essence of meditation lies in seeing one's nature—just as still water naturally lacks ripples, this awakened state must be maintained not only during seated practice but throughout daily life.

This scripture describes the state and methods of attaining enlightenment through cultivation:

When meditative stability (Ding) matures into wisdom, its infinite marvelous functions manifest as the spiritual powers of all Buddhas. Seeking its essence, one finds only empty stillness throughout the ten directions - not even the concepts of "Xi Yi" (Daoist term for the supremely subtle state) or "Huanghu" (the realm of seeming existence and non-existence) remain. Deliberate searching instead leads one astray from the true Dao, yet even the notion of "astray" shouldn't be clung to. The original mind is like empty space - how could there be gain or loss?

The key lies in relinquishing all attachments, thoroughly purging every discriminating thought. Then naturally, perfect brightness will suddenly appear, indistinguishable from all Buddhas. The physical body is but temporary bondage - one may harmonize with worldly light while acting without intention, indifferent to praise or blame. This body is merely a temporary lodging; the true master "Vairocana" (referring to Buddha-nature or true suchness) neither comes nor goes, revealing birth and death as illusions.

When asked what Vairocana looks like, know that any form isn't it. Every blade of grass and tree appears different yet fundamentally identical. All phenomena seem distinct but share one essence. Recognize the original mind's luminous pearl (Mani jewel), without clinging to methods. Like medicine curing illness, the remedy should be abandoned after healing. The confused mind needs guidance, but upon awakening, even methods must be discarded - like wiping dust from a mirror to reveal its natural radiance.

All mental constructs are fundamentally illusory - complete detachment from appearances is essential. Only beyond appearances lies supreme truth. To adorn the Buddha-land, practice impartial compassion to relieve suffering - this is the original Bodhi vow. Cultivating both merit and wisdom leads to fruition. The slightest attachment bars one from the Buddha-Dao. Ordinary beings cycle through six realms due to emotional clinging. Dao practitioners must strengthen their resolve, hardening their hearts like iron to see through familial bonds.

Maintain the original mind's radiance constantly, free from desire and attachment to all phenomena. Where then would heaven or hell exist? Thus one masters their destiny - neither rising nor falling in emptiness, journeying through pure lands while abiding eternally in Bodhi. Like Guanyin's thirty-two response bodies (the various manifestations of Avalokiteshvara), one may manifest infinitely according to conditions.

The essence is: Shatter all attachments, return to the original mind's luminous emptiness, and interact with the world freely without contamination.

This scripture reveals the transcendent state of practitioners and their critique of worldly cultivation through two sections.

The first part depicts the liberated state of a realized being: He calls himself the "guest of no-mind Zen," no longer attached to dualistic choices. Like a black ox that has turned completely white (symbolizing spiritual transformation), though others see him as mad, they don't recognize the priceless treasure concealed beneath his coarse robes. When he speaks of emptiness, his words are as hard to grasp as swallowing dates whole - this realm is comprehensible only to Buddhas. The text criticizes practitioners who engage in mere verbal disputes, clinging to trivialities while missing the essence, like holding a precious pearl yet trapped in subject-object duality, far removed from true awakening. Though they've studied the Dao for years, their arrogant minds lead to wasted lives, all due to stubborn attachments and heavy karmic obstructions.

The second part, "Ode to No-Mind," humorously describes the cultivation state: My mind resembles uncarved stone, following all things without forced practice, yet committing no wrongs; neither contriving benefit for others nor acting selfishly, unbound by precepts or taboos, ignorant of worldly rituals and virtues. Hungry, I eat; thirsty, I drink; tired, I sleep; hot, I shed clothes; cold, I add blankets - free from anxious thoughts or fluctuating emotions, indifferent to life-death or fame-shame. Life is but a temporary inn, as carefree as birds in the woods, coming and going without attachment.

(Note: The "black ox turning white" is a Neidan (internal alchemy) term symbolizing the manifestation of primordial nature through cultivation; "coarse robes concealing jade" alludes to the Daode Jing, illustrating how realized beings appear ordinary yet harbor inner treasures; "wondrous source of spiritual awareness" refers to the origin of enlightened mind.)

This passage elucidates the Daoist cultivation state of "Wuwei (non-action) spontaneity" and the wisdom of "illuminating the heart to perceive true nature." Its core teachings are:

The first part describes the attitude of a realized Daoist master:

• Neither actively pursuing nor avoiding anything, refraining from judgments of beauty or ugliness, good or evil
• Not deliberately choosing secluded or bustling places, accepting food and drink as they come
• Avoiding gossip about others' faults, abstaining from self-praise, treating all people equally regardless of status
• Maintaining equanimity toward gratitude or grudges, gain or loss, responding to events only as they arise
• Not being deluded by external appearances, understanding that gender distinctions and sensory perceptions are illusory manifestations
• Cultivating a luminous and complete mental state, reflecting all phenomena clearly like the moon's reflection in water

The second part, composed in the "Moon Over West River" poetic form, conveys Chan Buddhist insights:

1. There's no need to forcibly eliminate distracting thoughts or pursue ultimate truth (zhenru), as all beings inherently possess Buddha-nature

2. Enlightenment and delusion are separated by a single thought—sudden awakening can immediately transcend the cycle of rebirth

3. All phenomena are fundamentally neither born nor extinguished; distinctions between good/evil and sin/blessing are human constructs

4. Using the "bright mirror" metaphor for original mind: wiping away the dust reveals the truth of heaven and earth

5. Buddha-nature resembles moonlight reflected in countless rivers—it can manifest in the tiniest detail or pervade the entire trichiliocosm (three thousandfold world system)

6. True Dharma (ultimate truth) transcends verbal expression, like discussing dreams within a dream—ultimately illusory

7. Spiritual practice ripens naturally like a melon detaching from its vine; no need to cling to methods, as realization occurs spontaneously

Key term explanations:

• Zhenru: In Buddhism, the eternal and unchanging ultimate truth
• Trichiliocosm: The Buddhist cosmological concept of the entire universe
• Karmic defilements: Metaphor for the afflictions and attachments that obscure original mind

The entire passage emphasizes transcending dualistic thinking to return to the innate purity of one's fundamental nature—a state beyond words and concepts that requires direct personal realization.

This scripture primarily discusses the realms and methods of cultivating the Dao and realizing truth, with the core teaching being letting go of attachments and following natural spontaneity. Here's a plain interpretation:

Those who cultivate the Dao should relinquish distinctions between good and evil, unconcerned with gain or loss, honor or disgrace. Regardless of external changes between light and darkness, maintain inner peace—eat when hungry, drink when thirsty. Keep the heart-mind (Shen) pure and tranquil, at ease whether sitting or reclining, like a deep pool of autumn water where fish startled by wind come and go as they please.

When facing external circumstances, don't forcibly suppress them—even enlightenment (Bodhi) is just a provisional designation. Form and emptiness, light and darkness are originally one—don't rigidly separate truth from falsehood. True awakening is the Pure Land itself—no need to cling to India's Buddhist holy sites or Caoxi (the ancestral home of Chan Buddhism). The Western Paradise isn't in the West—realizing enlightenment here and now is Amitabha manifest.

Don't differentiate self from others—the Dharma body (Buddha-nature) is inherently without distinctions. When thoughts arise, don't chase them; what's seen isn't necessarily real, what's heard isn't necessarily false. All phenomena don't know each other—how could birth and death bind you?

Clinging to cultivation practices while seeking karmic rewards may at best lead to heavenly rebirth—like an arrow shot toward clouds that must eventually fall. Better to return to the true reality of Wuwei (non-action), recover original simplicity, forget conceptual knowledge and follow spontaneity—only then can one realize the patient endurance of the unborn (highest enlightenment).

Having caught the fish or rabbit, forget the fishing net (metaphor for abandoning methods after awakening). After crossing the river, discard the raft. Before awakening, words provide guidance; after awakening, transcend words. Though the four-line verse speaks of Wuwei, ultimately even this must be relinquished.

After awakening, don't seek extinction—teach beings according to circumstances. For those with wrong views, offer timely guidance using skillful means to help them recognize true reality. The five eyes (wisdom), three bodies (Buddha's three modes of being), four wisdoms, and six perfections (paramitas) must all be fulfilled—like the precious mani jewel that benefits both self and others.

Some today merely discuss Buddha-nature but become confused when encountering circumstances—no different from fools. Words must match deeds—use the sword of wisdom to cut through demonic obstacles—this is the Tathagata's (Buddha's) true wisdom.

To understand the wondrous Dao of the unborn, first recognize your true mind. This true mind has no form or sound—such is the pure Dharma body. This Dao is neither existence nor non-existence—don't deliberately seek it. Abandon dualistic extremes without clinging to the middle—true understanding marks superior capacity.

Note: "Patient endurance of the unborn" refers to complete realization of the truth that "all dharmas are unarisen"; the "mani jewel" is Buddhism's wish-fulfilling gem; the "six perfections" include generosity, discipline, patience, diligence, meditation, and wisdom.

This scripture elucidates the core principles of Neidan (internal alchemy), a Daoist cultivation method that harmonizes Jing (essence), Qi (vital energy), and Shen (spirit) within the body to attain longevity, using the symbolic language of the Yijing (Book of Changes).

The Daoist master Xue Daoguang, known as Perfected Purple Virtue, provides this commentary:

• The ordinary Dao (常道) follows nature's rhythm where Yang Qi governs life and Yin Qi governs death in perpetual cycles.
• Practitioners reverse this process: envisioning the human body as an alchemical crucible (with Qian and Kun trigrams representing the vessel), they gather primordial Qi (先天炁) to forge the internal elixir. This Golden Elixir then refines the physical form, ultimately achieving unity with the Dao and immortality.

The text employs Yijing cosmology:

1. Cosmic generation: From emptiness emerges Yin-Yang (两仪), which further differentiates into Four Symbols and Eight Trigrams (八卦)—all transformations producing auspicious or inauspicious circumstances.

2. Key cultivation correspondences:

• Tai (泰) and Pi (否) hexagrams depict the ascent and descent of Yin-Yang
• Zhun (屯) and Meng (蒙) hexagrams mark dawn and dusk practice periods
• Kan (坎) and Li (离) symbolize the body's water (kidney Qi) and fire (heart energy)
• Zhen (震) and Dui (兑) represent the dragon-tiger allegory for refined Jing and Shen

3. Cultivation precepts:

• Maintaining equilibrium (守中) brings supreme auspiciousness
• Avoiding extremes (遇亢) prevents imbalance
• Honoring cyclical change (as shown in Fu 复 and Gou 姤 hexagrams)
• Aligning practice with lunar phases mirrors Shen's waxing and waning
• Synchronizing breath with sunrise/sunset regulates the Qi-blood system (荣卫)

(Note: The character "炁" denotes pre-heaven primordial energy in Daoist terminology, distinct from ordinary respiratory Qi.)

This passage expounds the Daoist Neidan (internal alchemy) principle of "correspondence between heaven and humanity," where the patterns of Yin-Yang transformation across a year, month, and day are mirrored in human cultivation practices.

At the winter solstice, Yang Qi from the earth begins its ascent, corresponding to the Fu hexagram (一阳初生) in the Book of Changes. Similarly, the body's primordial Qi reaches a state akin to the Tai hexagram (地天泰) by the first lunar month when Yin and Yang are balanced. Practitioners condense a year's seasonal transitions into thirty days of practice, with each two-and-a-half-day period representing a solar term.

The moon's phases demonstrate this same principle:

• The new moon's first light after the lunar first day reflects the Fu hexagram
• The first quarter moon (half moon) on the eighth day corresponds to the Tai hexagram
• The waning moon after the sixteenth day manifests the Gou hexagram (一阴生)
• The last quarter moon on the twenty-third day aligns with the Pi hexagram

These lunar phases symbolize the waxing and waning of human Jing (essence) and Qi (vital energy).

Further condensed into twelve two-hour periods of a day:

• Zi hour (23:00-01:00) sees Yang Qi arising in the kidneys (Fu hexagram), initiating "advancing the Yang fire" (a cultivation term for guiding Yang Qi upward)
• Wu hour (11:00-13:00) witnesses Yin Qi emerging in the heart (Gou hexagram), commencing "retreating the Yin talisman" (guiding Yin Qi downward)

The Zi hour employs the Zhun hexagram (symbolizing creation), while the Wu hour uses the Meng hexagram (symbolizing enlightenment). Two hexagrams govern each day, cycling through sixty hexagrams over thirty days.

In Golden Elixir (Jindan) cultivation, practitioners first establish the "furnace and cauldron" (metaphors for the bodily foundation), using true Yin and Yang (the primordial Jing and Shen) to attract the Supreme Ultimate's primordial Qi (innate energy). As described in the Zhouyi Cantongqi, the Qian and Kun hexagrams represent the furnace and cauldron, while Kan and Li hexagrams symbolize the medicinal ingredients (cultivation materials), with other hexagrams circulating through the thirty-day cycle.

The core teaching demonstrates how observing nature's Yin-Yang transformations informs the precise timing and fire-regulation (huohou) techniques in Neidan practice.

This scripture elucidates the core principles of Daoist Neidan (internal alchemy) practice. Master Ziyang employs various metaphors to illustrate that the essence of cultivation lies in harmonizing the two energies of Yin and Yang:

What practitioners often call "Fu Fire" (the regulation of firing times in Neidan) can be metaphorically described through diverse concepts: Heaven and Earth, Dragon and Tiger, Zhen and Dui (two trigrams from the Bagua), husband and wife, hun and po (ethereal and corporeal souls), Kan and Li (the water and fire trigrams), or lead and mercury (alchemical terms symbolizing Yin and Yang). All these represent the authentic Yin and Yang energies within the human body. When these two energies merge in the middle Dantian (the chamber of the Yellow Path), the internal elixir is formed—this is the meaning behind "abiding in centrality brings the auspicious yellow robe."

After forming the internal elixir, it must be nurtured and refined through "true fire" (primordial Yang Qi). This fire has no fixed location but circulates throughout the body. Just as the sun rises in the east and sets in the west, bringing the alternation of day and night, practitioners must likewise regulate the energies of Yin-Yang and the seasonal transitions within each day and night, aligning the body's Qi-blood circulation with the natural rhythms of Heaven and Earth.

Human "Jing" (essence) corresponds to Heaven's primal water (number one), while "Shen" (spirit) corresponds to Earth's secondary fire (number two). The movement of one's vital energies should emulate the natural patterns of Heaven and Earth's Yin-Yang and the Five Phases (Wood, Fire, Earth, Metal, Water).

The scripture emphasizes: All these metaphors serve to explain cultivation principles. Once the truth is grasped, one need not cling to specific analogies. It's like pointing at the moon—the focus should be on seeing the moon, not staring at the finger. The wise grasp the simple essence, while the confused complicate matters further. Thus, truly perceptive practitioners reading classics like the Cantong Qi don't rigidly adhere to literal interpretations.

Finally, Master Daoguang observes: Master Wei Boyang used the symbols of the Yijing to expound the Golden Elixir path, hoping scholars would comprehend its true meaning. Once the essential techniques of elixir cultivation are mastered, all metaphors can be set aside; once the true mechanism of fire regulation is understood, the trigrams and line statements become unnecessary constraints. This addresses his concern that later readers of the Cantong Qi might merely memorize the text without realizing the need to transcend appearances and grasp the underlying truth.

This passage reveals the mysteries of Neidan (internal alchemy), the Daoist practice of cultivating Jing (essence), Qi (vital energy), and Shen (spirit), focusing on how to achieve longevity through the harmonization of Yin-Yang.

It begins by stating: These profound principles are nearly impossible for ordinary people to comprehend without direct transmission from an accomplished master—even then, one might grasp but a ten-thousandth part of their profundity.

The text then employs a poem dedicated to Daoist Liu as metaphor: Time flies like a shuttle—human life is fleeting. Even Pengzu (Jian Shou, the legendary figure who lived eight hundred years) enjoyed but a brief existence, as transient as lightning. Within a mere century's span, through alternating cold and heat, aging creeps unnoticed. Though surrounded by descendants, none can ultimately escape the cycle of life and death.

The cultivation method is then explained: Most people vainly seek immortality through medicinal herbs or Waidan (external alchemy involving lead and mercury). The true path lies within the body. The essential points are:

1. "Seeking crimson blood in the Kan palace": Drawing the primordial Qi (symbolized by crimson blood and yang lead) from the kidney region (represented by the Kan trigram)

2. "Refining yin essence in the Li position": Harmonizing the heart-mind (symbolized by yin essence and yin mercury) in the heart region (represented by the Li trigram)

3. These two processes interact like the cosmic coupling of Qian (Heaven) and Kun (Earth), gestating the inner elixir within the Dantian (elixir field, corresponding to the Kan palace)

Crucially, the lead and mercury mentioned here aren't actual metals but metaphors for the body's vital substances. Successful practice requires perfect timing, just as the "Yellow Matchmaker" (symbolizing true intention) must mediate the Yin-Yang union.

In essence: One must harmonize internal Yin-Yang energies at precisely the right moment using correct methods, rather than seeking external substances. This demands guidance from an enlightened teacher—attempting alone invites certain error.

This scripture elucidates the principle of Yin-Yang union in Daoist Neidan (internal alchemy) practice, employing the metaphor of marital union to reveal the essence of elixir refinement.

The core teaching states that during cultivation, the two energies of Yin and Yang (symbolized as husband and wife) require a "matchmaker" for their union—this intermediary is called the "Yellow Matron" (Huangpo), representing true Earth energy that harmonizes Yin and Yang. As the Cantongqi (Triple Unity Classic) describes, during the moon's transition between dark and new phases when Yang energy first stirs, the Yin dragon (female dragon) and Yang tiger (male tiger) must be mediated by the Yellow Matron to unite.

The text further explains the technical terms "Golden Duke" (Jingong) and "Crimson Maiden" (Chanü):

• "Golden Duke" signifies lead (representing primordial Qi), embodying metal nature like the White Tiger, yet its essence is true Yang born from water ("the tiger emerges from water")
• "Crimson Maiden" denotes mercury (representing original spirit), embodying wood nature like the Azure Dragon, yet its essence is true Yin generated from fire ("the dragon arises from fire")

In alchemical practice, the Golden Duke (lead) and Crimson Maiden (mercury) resemble bride and groom who can only wed through the mediation of the Yellow Matron (true Earth energy). This process, termed "combining lead with mercury," constitutes the crucial stage in forging the Golden Elixir. Multiple classical texts are cited to emphasize that without the Yellow Matron's harmonizing function, the Yin and Yang energies cannot achieve genuine fusion.

This scripture describes the "dragon-tiger copulation" phenomenon in Daoist Neidan (internal alchemy) practice, using symbolic imagery to portray the fusion of yin-yang energies within the body:

When the practitioner sits in meditation, the dual energies of yin and yang (symbolized as the Azure Dragon and White Tiger) begin resonating within. The "Western River" represents kidney water (yin), while the "Eastern Sea" symbolizes heart fire (yang). When true yin (the tiger) encounters true yang (the dragon), their interaction creates turbulent energy waves in the body, like two fierce beasts locked in combat. The ancient verses depicting "the Azure Dragon chasing the tiger" and "the crimson birds converging" precisely capture this intense state of water-fire interaction.

The alchemical process requires mediation by the "Yellow Matron" (the spleen-earth at the central palace, serving as harmonizer) and the "Gentle Elder Ding" (representing mild yang fire). As Master Yin Zhenjun revealed, this profound mystery actually resides in the state of the "infant" (primordial qi), which constitutes the core secret of cultivation.

When the energy turbulence reaches its peak, it can even "startle celestial and earthly spirits" (indicating the full mobilization of bodily essences). After the "clouds disperse and rain ceases" (energy stabilizes), an "Mysterious Pearl" (the inner elixir) condenses at the "muddy base" (the yellow court central palace, the Dantian region). As Master Ziyang explained, daily accumulation through practice gradually forms the precious Golden Elixir. The "Mysterious Pearl" sought by the Yellow Emperor refers precisely to this cultivation achievement attainable only through a state of no-thought (wangxiang).

This passage explains the process and states of attainment in Daoist Neidan (internal alchemy) practice, rendered in modern terms as follows:

In cultivation, one should avoid excessive deliberation—just as plants grow gradually from their roots, we must continuously nourish the innate Jing (essence) and Qi (vital energy) within. Master Sanguzi said: Laying the foundation requires one hundred days of cultivation, maintaining gentle nurturing like the movement of stars. Simply preserve your essence without leakage, and the kidney water (spiritual water) will naturally become abundant while the heart fire harmonizes. When primordial Qi becomes sufficient...

After ten months of practice (symbolizing the gestation period), one sheds the mortal body. At this stage, one suddenly perceives the ordinary physical form becoming spiritually animated. Master Ziyang described it as "swallowing a single spiritual pill"—this is the state of "shedding the mortal body" and "connecting with the divine." The Cantong Qi (Token for the Agreement of the Three) states that when the Golden Elixir enters the body, it permeates like wind and rain. Some wonder whether this refers to Neidan or Waidan (external alchemy), but it actually describes the process of "returning the elixir," where formless Qi transforms into tangible substance.

The specific method involves: first gathering the primordial chaotic Qi (True Unity Qi) of heaven and earth to establish the foundation, then observing the cyclical patterns of the cosmos to adjust one's practice. One seizes the creative opportunities of heaven and earth according to the waxing and waning principles of Yin-Yang (represented by the Kan and Li trigrams). The Qian and Kun trigrams symbolize the cauldron and furnace, while Kan and Li represent the medicinal substances; the remaining sixty hexagrams correspond to fire regulation. Just as fruit ripens or a fetus reaches full term, after ten months of proper fire regulation, the original spirit (Shen) can transcend physical limitations and unite with the Dao. Hence the classic says, "it enters the mouth and settles in the abdomen."

The Cantong Qi compares the Golden Elixir to an embryo within an egg—after ten months of development, it takes form. At this stage, practitioners shed their mortal bodies, attaining the state of "generating being from non-being," where the spirit can leave the physical form (a body beyond the body). Those who cling to their flesh find transcendence difficult, but those who can exit through the Niwan Palace (crown point) roam freely between heaven and earth, their names recorded among the immortals, becoming true realized beings. This marks the ultimate achievement of a true cultivator.

Such profound mysteries of cultivation are rare in the world—those without karmic connection to the Dao cannot comprehend them. Without accumulated merit from past lives, one would hardly encounter these true methods in this lifetime. Having encountered them, one must practice diligently, for time flies like an arrow. Just as one must weave nets before catching fish, cultivation requires thorough preparation.

This scripture conveys several key teachings:

The first section records the admonition of Master Ziyang (a prominent figure in Daoist Neidan tradition) to Immortal Liu: "Having understood the principles of alchemical practice for so many years, why do you still not focus your mind on cultivating internal elixir (where 'mercury and lead' symbolize the Jing and Qi of Neidan practice)? Do not wait until the flame of life is extinguished by the wind of time, suffering in the cycle of rebirth before lamenting your fate." This emphasizes that Neidan cultivation depends entirely on personal practice, not external aids.

The second passage criticizes contemporary fake practitioners: "Many nowadays pretend to follow the Dao, wearing monastic robes yet unable to explain basic alchemical terms like 'metal and wood' (representing Yin-Yang elements in Neidan). In truth, metal (emotion) is nurtured by lead (original essence), while wood (nature) is consolidated by mercury (original spirit). Only when lead and mercury unite can the Golden Elixir be perfected." Those ignorant of these principles cannot possibly discuss authentic alchemy.

The third segment reveals the true path: "Some advocate peripheral methods like breath cultivation or grain avoidance, yet the supreme approach remains the 'Method of Embracing Primordial Truth by the Supreme Unity' (the highest Daoist practice). Authentic Neidan cultivation relies on the Supreme Unity's primordial Qi, harmonizing the Five Phases (represented by five stars) within the body and blending Yin-Yang (symbolized by sun and moon) - this alone constitutes the correct path."

The concluding note by Daoist Fuchu Gao Shiming explains: While studying the Wuzhen Pian (Awakening to Reality), he discovered the missing poetic instructions that Master Zixian had written for Daoist Liu. After years of searching, he finally found Li Jianyi's (Jade Stream Master) detailed commentary in Daoist texts, allowing this lost scripture missing for centuries to resurface. He recorded this discovery in the first month of the Tianqi era's second year (1622 CE) of the Ming Dynasty.

(Note: Terms like "mercury-lead" and "metal-wood" are Neidan terminology representing original spirit-essence and Yin-Yang concepts; "Supreme Unity Embracing Truth" refers to cultivating primordial Qi; "five stars" correspond to the Qi of five viscera.)
