《紫陽真人悟真直指詳說三乘祕要》

The Direct Explanation of Purple Yang Perfected Person's Awakening to Truth: Secret Essentials of the Three Vehicles expounds the fundamental principles of cultivation:

Before the chaos of the cosmos divided, there existed only a state of empty stillness, provisionally called the "Dao." This Dao manifests the primordial qi (vital energy), which is neither movement nor stillness, neither pure nor turbid—so profoundly mysterious that sages named it "the True One Qi of Primordial Chaos." This qi differentiates into the two energies of yin and yang, which correspond to heaven and earth, male and female. Just as heaven and earth interact to generate all things, and male and female unite to create life, all phenomena in the world arise through the union of yin and yang.

If practitioners merely use tangible substances like metals, minerals, and herbs, or rely on the jing (essence), qi, and shen (spirit) of the physical body for alchemical work, they are working with conditioned, material forms. All formed things eventually perish—how could they possibly transcend physical limitations? As long as one remains within heaven and earth, no one escapes the natural law of yin-yang's cycles of life and death. Even with proper cultivation methods, one might prolong life temporarily, but ultimately, like an arrow shot into the air, one must fall back down.

Therefore, the authentic cultivation method involves gathering the primordial qi before form to refine the elixir: First transform the physical body into qi, then refine qi into shen, until finally the shen merges with the Dao, attaining a formless, imageless state. Only then can one transcend the constraints of heaven and earth and master the transformations of yin-yang. The elixir body born from this primordial qi becomes indestructible. It's like moving a massive vat—you must stand outside it to shift its position. The true primordial qi arises before heaven and earth. Sages use substances of the same kind (referring to primordial qi) to attract and coalesce it into the Golden Elixir, just as...

This scripture elucidates the essential methods and principles for refining the Golden Elixir (Jindan), the highest attainment in Daoist cultivation:

The text begins with metaphorical explanations of cultivation principles: Just as the yangsui (an ancient fire-making tool) draws fire from the sun and the fangzhu (an ancient water-gathering vessel) draws water from the moon, spiritual practice similarly relies on sympathetic resonance between corresponding elements. Thus, the interaction of Yin and Yang energies is likened to the dance of "True Dragon and True Tiger" circulating within the alchemical cauldron. The poetic line by Lü Dongbin—"Naturally the furnace hosts the tiger coiling with the dragon"—precisely captures this dynamic.

The "corresponding elements" mentioned here refer not to material substances but to invisible harmonies. Among all phenomena, the most precious is the spiritual Qi (vital energy) that aligns with the fundamental source of human nature (xing) and life force (ming). The "True Lead and True Mercury" used in cultivation are not ordinary minerals but represent the refined states of Yin and Yang energies—analogous to the lunar phases of first quarter (eighth day) or last quarter (twenty-third day) when Yin and Yang are perfectly balanced (symbolized by "eight ounces of Dragon and half-pound of Tiger," combining to make one jin in traditional measurement). During these phases, the "water source" (symbolizing primal energy) is clearest, containing Qi without material form. Through the sympathetic vibration of such purified energies, one can attract the Primordial True Unity Qi (the most fundamental cosmic energy).

Practical cultivation methods include:

1. Environmental preparation: Selecting an auspicious geomantic site to construct a dedicated alchemical chamber, building a three-tiered ritual platform, hanging mirrors on all sides, and arranging the Dragon-Tiger cauldron furnace.

2. Instrument preparation: Using clepsydras (ancient water clocks) to precisely track time, regulating the advance and retreat of "water and fire" (symbolizing Yin-Yang transformations), along with other auxiliary tools.

3. Material support: Securing sufficient financial resources—Yin Zhenjun particularly emphasizes that "without adequate wealth, the Golden Elixir cannot be perfected."

4. Collaborative practice: Requiring three like-minded practitioners to work in harmony, commencing their joint practice during early August (when Yang energy first stirs). The lead cultivator performs the Yu Steps (a ritual Daoist gait), controlling the Dragon (Yang energy) with the left hand and the Tiger (Yin energy) with the right, meticulously harmonizing with energetic rhythms.

This passage reveals the core concept of Neidan (internal alchemy) practice—integrating cosmic patterns (such as lunar phases) with human cultivation. It emphasizes the coordination of celestial timing, terrestrial advantages, and human harmony, as well as the transformation between tangible and intangible energies.

This passage explains the process of fire regulation (huohou) in Daoist Neidan (internal alchemy) practice and the formation of the Golden Elixir (Jindan).

On mastering fire regulation:

The practitioner must precisely grasp the Yin-Yang cycles with the meticulous care of a general strategizing a campaign. As Lü Dongbin taught, successful alchemy depends entirely on disciplined practice—even the slightest deviation will prevent elixir formation. One must attentively observe temporal changes (using ancient water clocks as reference) to accurately adjust the firing process. Missing the critical moment of the Fu hexagram (midnight, when Yang qi first emerges) will ruin the elixir. As Zhang Boduan warned, practitioners must strictly follow celestial rhythms.

On the elixir formation process:

When the Three Treasures—Jing (essence), Qi (vital energy), and Shen (spirit)—unite in perfect coordination, the "True Unity Qi" (zhenyi zhi qi) manifests within half a watch (an hour). This coalesces into a Golden Elixir the size of a millet grain in the lower Dantian (the Elixir Field). When this luminous pearl appears in the "North Sea" (another Dantian metaphor), the practitioner must immediately guide it with focused intention (symbolized by the legendary Moye sword).

On the elixir's efficacy:

Ingesting this elixir transports one beyond ordinary existence. Zhang Boduan's famous verse declares: "When a golden pellet enters my belly, I realize my fate is not heaven's to decide." Once stabilized in the Dantian, it attracts and consolidates the body's vital essences. Through proper firing, these transform into the golden liquid of the Returned Elixir.

On fire regulation principles:

The firing process fundamentally follows Yin-Yang qi transformations. The six watches from midnight to noon belong to Yang fire, while noon to midnight belongs to Yin cycles. By calculating heaven-earth numerical correspondences (216 for the Qian hexagram, 144 for Kun), practitioners can harness 4,320 years of primordial energy to nurture the elixir, ultimately forming the sacred embryo.

As Laozi summarized: Yang qi emerges at midnight, Yin qi begins at noon—their perpetual cycling mirrors fetal development in the womb. Through accumulating external virtue (De) and internal Yang qi, adepts perfect the Great Dao of the Golden Elixir.

This passage describes the advanced stage of Daoist Neidan (internal alchemy) practice known as the formation of the "Golden Liquid Returned Elixir" and its miraculous effects.

When the fire of Yang Qi (the cultivated energy) circulates naturally within the body, it generates a golden, liquid-like refined substance. This energy begins at the Weilu point (at the base of the spine) and ascends along the spinal column, passing through the Jiaji gateway (a crucial acupoint on the back) until it reaches the Niwan Palace (upper Dantian) at the crown of the head, then descends into the mouth. This essence, resembling a sparrow's egg in appearance with a sweet taste, is what we call the "Golden Liquid Returned Elixir." By gradually swallowing it down to the Dantian (energy center), one can form the "Sacred Embryo" and nurture the "Infant" (referring to the cultivated Shen or spirit).

Just as ordinary pregnancy requires ten months, the practitioner must undergo ten "fire phases" (referring to the precise regulation of alchemical processes). When the practice reaches completion, the practitioner undergoes a complete physical transformation into a body of pure Yang, no longer troubled by cold, heat, hunger, or thirst. At this stage, one may retreat to deep mountains for nine years of wall-facing meditation, attaining a state of mental clarity where all distinctions between self and objects dissolve—this is called "the immortal embracing the One" (symbolizing unity with the Dao).

After nine years of cultivation, the Wuwei (non-action) nature becomes perfectly realized, wisdom arises spontaneously, the pure Yang body attains profound subtlety, and the Shen (spirit) becomes numinously perceptive. At this point, one's innate nature and vital force completely merge with the Dao, reaching a formless and imageless state. This formless existence can manifest according to circumstances: transforming into wind when encountering wind, becoming rain when meeting rain, or assuming the forms of water and fire as needed. One can freely shapeshift into birds, beasts, flowers, or trees, appearing and disappearing without trace—here one moment and gone the next.

The practitioner can manifest countless emanations, responding to beings' needs according to conditions. Like the moon simultaneously reflecting in countless rivers and lakes while its true form remains in perfect stillness, the adept's true being never deliberately acts. This represents the supreme state where spirit, form, innate nature, and vital force become completely unified with the Dao.

This scripture recounts the cultivation method of the "Ninefold Golden Elixir of Great Return" transmitted by Master Ziyang (Zhang Boduan, patriarch of Daoist Neidan [internal alchemy]), emphasizing the importance of dual cultivation of nature and life (xingming shuangxiu).

The core teaching states that all spiritual practice must ultimately return to the silent, empty source. The sages reluctantly named this supreme state the "Ninefold Golden Elixir of Great Return," also called the "Indestructible Diamond Body," representing the highest path of authentic cultivation. Master Ziyang particularly propagated this method, having perfected a dharma-body like true gold through practice, manifesting in majestic and compassionate forms to liberate all beings.

The text records several key events from the master's life: First, he transmitted the "Way of Nature" (methods for cultivating mind and temperament) to disciple Liu Fengzhen, demonstrating nirvana; later, he manifested his true form through the "Way of Life" (methods for refining the physical body) at Mount Wangwu. On the fifth day of the third lunar month in the Yuanfeng era, during his liberation from the corpse (a Daoist method of transcendence), he left this verse: "The wondrous function of the single spirit perfectly penetrates the dharma-realm," fully embodying the state where nature and life are jointly cultivated, with both form and spirit attaining perfection. Master Ziyang dwelled in the world for 96 years, propagating profound Daoist teachings throughout his life, composing elegant poetry to guide later practitioners.

He deliberately titled his work Awakening to Truth to emphasize comprehending the "truth of nature and life." Concerned that later generations might either focus solely on refining the body while neglecting mind cultivation, or cultivate only the mind while disregarding physical refinement, he employed two concepts to enlighten those with wisdom: "thorough awakening to true suchness" (realizing one's true nature) and "the wondrous treasure of the physical form" (refining the body). This helps practitioners understand the dual cultivation path, ultimately transcending the cycle of the three realms.

The scripture concludes with this admonition: Cultivating the Golden Elixir requires finding the innate "single millet-sized pearl" (referring to the primordial qi within the body). Seeking it externally will never bear fruit. Like the pearl the size of a millet grain that the Celestial Worthy of Primordial Beginning suspended in emptiness, it symbolizes how the supreme Dao is supremely simple—residing within oneself.

This passage from Purple Sun True Person's Direct Explanation of Awakening to Reality: Secret Essentials of the Three Vehicles expounds the core principles of Daoist Neidan (internal alchemy) practice:

The Golden Elixir that surges forth from the mouths of assembled immortals represents the essence of cultivation. Though small as a millet grain (an ancient unit of measurement), it encompasses all phenomena between heaven and earth—boundless in magnitude yet infinitely subtle. Since ancient times, all sages who attained the Dao and achieved perfection did so through this "single grain elixir" to realize the supreme Dao.

While this principle appears simple, its fundamental truth remains inaccessible without guidance from a genuine master. Even with this understanding, achievement proves difficult without adequate material resources. And even with accomplishment, one cannot reach the ultimate state of "embracing the One" (unity of heaven and humanity) without attaining enlightenment of one's true nature.

The cultivation of life (physical practice) requires transmission from a master and manifests through actual practice. However, the cultivation of nature (spiritual refinement) differs—it cannot rely on external knowledge, or one remains confined to intermediate levels. Only through inner awakening can one access the highest vehicle of nature cultivation.

In truth, the highest state of nature cultivation transcends distinctions between enlightenment and non-enlightenment, reaching the realm of "supreme non-duality" (beyond all differentiation). Practitioners who comprehend their master's true transmission, grasp celestial mechanisms, refine the divine elixir, undergo bodily transformation, and awaken to their original mind can directly surpass the highest levels to attain Wuwei (non-action) perfection. Ultimately, both form and spirit become wondrously refined, enabling one to ride cranes and dragons through immortal realms.

The later-mentioned "art of strengthening armies to achieve victory" also contains Golden Elixir refinement secrets: practicing during the mid-autumn full moon when Yang energy first stirs, adopting specific postures at the altar (left hand subduing the dragon, right hand seizing the tiger)—these constitute concrete cultivation methods.

This passage discusses two core methods in Daoist Neidan (internal alchemy) practice: the "Art of Strengthening the Army to Achieve Victory" and the "Method of Enriching the State to Pacify the People."

Regarding the "Art of Strengthening the Army to Achieve Victory":

This is a metaphor for controlling the "fire times" (huohou) during cultivation. Just as warfare requires precise tactics, practitioners must skillfully harmonize the Yin and Yang energies (referred to as "one civil, one martial"). The movement of true Qi between the Dantian (energy center, called the "Mysterious Gate") and the perineum (called the "Feminine Door") should be as precise as military maneuvers, with breathing rhythms (the "water clock" metaphor) aligned with natural cycles (the celestial orbits). Here, the "army" represents the vital essences within the body (symbolized as Dragon and Tiger), while "achieving victory" signifies the union of Yin and Yang (coupling). Proper cultivation can swiftly produce the Golden Elixir. The author employs sixteen poems (eight each for Dragon and Tiger) to illustrate the principle of Yin-Yang balance, with five-character verses symbolizing how a single two-hour period (one shichen) can refine a single golden elixir pellet.

Regarding the "Method of Enriching the State to Pacify the People":

This explains how to utilize Yin and Yang energies in cultivation. All phenomena in heaven and earth originate from the primordial Qi (Yiqi): the light, clear Yang energy ascends to form heaven, while the heavy, turbid Yin energy descends to form earth. Pure Yang energy rising to heaven becomes immortals (xian), while pure Yin energy sinking to earth becomes ghosts. Humans stand between these realms, containing both Yang and Yin energies. Through cultivation, if one completely eliminates Yin energy and transforms it entirely into Yang, one becomes an immortal. Without cultivation, when Yang energy is exhausted and only pure Yin remains, one becomes a ghost.

This scripture elucidates the core principles of Daoist Neidan (internal alchemy) practice, using the cosmic interplay of Yin-Yang to illustrate methods for cultivating the human body.

The essential meaning conveys that Heaven belongs to Yang, Earth to Yin, and humans—endowed with the refined Qi (vital energy) of both—are the most spiritually precious beings. Practitioners must gather the innate True Yin and True Yang energies (referring to the original Jing (essence) and Shen (spirit) within the body). Through specific cultivation methods, these primordial energies coalesce into the "elixir" (Neidan), stored in the Dantian (energy center near the lower abdomen's sea of Qi). Like all nations paying homage to their ruler or stars revolving around the North Pole, the body's energies naturally converge upon this central reservoir.

The alchemical process mirrors the conception of life through parental union, requiring perfect harmony between Yin and Yang energies. Through cyclical operation of "Yin talismans and Yang fire" (Neidan terminology denoting the coordination of breath and intention), practitioners simulate seasonal transformations within the body. After prolonged cultivation, a "pearl of elixir" (the materialized Neidan) gradually matures in the Dantian.

The text employs statecraft as metaphor for self-cultivation: the body resembles a nation, with Jing and Qi as its people. The inner elixir functions as the sovereign, while "fire times" (the mindful regulation during practice) serve as ministers. Only through proper coordination between ruler and officials can the nation prosper—just as when essence and Qi become abundant, one attains the "prosperous nation and contented people" state described in the Western Florescence Scripture as "complete essence and sufficient Qi."

Finally, the author mentions composing sixty-four quatrains following the Yi Jing's hexagram structure, plus twelve "Moon Over West River" poems corresponding to monthly fire times—all detailing specific cultivation procedures. The entire process must follow this sequence to achieve the "immortal embracing the One" (union with the Dao) state.

Key points:

1. Core practice: Gathering primordial Qi, refining essence into energy

2. Methodology: Yin-Yang harmonization, fire time regulation

3. Ultimate goal: Forming the inner elixir, transcending mundanity

4. Statecraft analogy: Emphasizing holistic mind-body harmony

(Note: Terms like "Yin talismans and Yang fire" and "fire times" are specialized Neidan terminology referring respectively to specific breathing techniques and intentional control during practice.)

This scripture elucidates the core meaning of "the immortal embracing the One" (a state where practitioners unite with the Dao) in Daoist cultivation. When adepts reach perfection, their physical forms transform into pure Yang Qi (the highest energetic state in Daoist thought). True practitioners retreat to secluded places, purifying their minds through prolonged wall-facing meditation (a form of closed-door cultivation), achieving complete fusion of their Shen (spirit) with the Dao.

The scripture states: The Dao is human nature, and the root of nature lies in the heart. Heart and nature are originally one, capable of generating infinite transformations. The natural state of ordinary people in daily life is actually a manifestation of the Dao. Those who truly comprehend this, transcending the limitations of form and language while maintaining inner emptiness and stillness (the Daoist cultivation state of "empty heart, full belly"), focusing on unity with the Dao, can attain the immortal realm after nine cycles (nine years) of cultivation.

Here, "nine" represents the ultimate Yang number, while "one" is but a provisional name for the Dao. "Embracing the One" actually means transcending all attachments. Immortals who reach this state relinquish bodily senses, surpass distinctions between ordinary and sacred, eliminate self-attachment, and achieve complete mental unity, roaming in absolute freedom. After nine years of cultivation, the Wuwei (non-action) nature spontaneously perfects itself, the formless Yuan Shen (primordial spirit) naturally becomes mysterious, capable of manifesting countless emanations and responding to all phenomena while their true essence remains eternally in supreme stillness.

The scripture provides examples: Ancient immortals after attaining the Dao could simultaneously manifest extinction (nirvana in Buddhist terms) and appear in physical form; after the Tathagata's nirvana, he manifested a golden coffin, while Bodhidharma, after nine years of wall-facing meditation, could still return westward carrying his sandal (a famous Buddhist allusion). These demonstrate that only by reaching the state of "dual cultivation of nature and life, with both form and spirit becoming wondrous" can one possess such divine transformations.

This passage emphasizes that the true path of immortality lies in long-term cultivation that elevates both spirit and physical form to the wondrous state of unity with the Dao.

This scripture primarily discusses the essence and cultivation methods of "Xing-Dao" (the Way of Original Nature, one's innate true nature):

1. On the essence of Xing-Dao:

• It is formless, boundless, and ultimately indescribable through language
• All sentient beings (both human and non-human) are fundamentally equal in their original nature
• Since beginningless time, whether manifested forms with names or formless nameless phenomena, all are inherently complete and perfect
• This pure and perfect original nature is innate to all beings

2. Regarding scriptural texts:

• Though the Daoist canon contains over five thousand volumes, these are merely expedient means used by sages to express the inexpressible
• The purpose is to help people understand the Dao through words, but once truly understood, the words should be let go
• Quoting the Diamond Sutra: "If the Tathagata says he has preached any doctrine, he would be speaking falsely"
• The author explains that writing about Xing-Dao is similarly an unavoidable concession, and further elaboration would be superfluous

3. Key cultivation points:

• Those with wisdom should directly perceive their original mind and realize it through personal experience
• Whether in bustling noise or quiet solitude, in taverns or pleasure quarters, one should maintain constant awareness
• Attain the state where "all phenomena are undifferentiated, everywhere is harmonious"
• Perceive the entire dharma realm as one eye or one hand, marvelously functioning without obstruction
• Then realize that original nature has always been complete - neither increasing nor decreasing
• Ultimately even the concept of "nature" must be transcended to reach the absolute state beyond thought

Key notes:

1. "Embracing the One" refers to maintaining the undifferentiated state of the supreme Dao

2. The "Diamond Sutra" is the Vajracchedikā Prajñāpāramitā Sūtra in Buddhism

3. "All deliberation ceases" means the cessation of all conceptual thinking

4. Emphasizes the cultivation method of "not establishing words and letters, directly pointing to the original mind"
