《悟玄篇》

Understanding the Mysteries: A Vernacular Interpretation

Human beings are born between heaven and earth, endowed with the Qi of Yin and Yang, hence the cycle of life and death. One may become a ghost (condensed pure Yin Qi) or cultivate immortality (pure Yang body). Refining Yang with Yin is relatively easy, just as refining Yin with Yang is not difficult. The methods used by those seeking immortality primarily involve refining Yin with Yang. When Yin Qi is fully refined and Yang Qi becomes pure, one achieves immortality.

The practice of refining Yin Qi follows specific methods: advancing the fire (cultivating Yang Qi) follows certain rhythms, while withdrawing the talisman (regulating Yin Qi) adheres to proper measures. Within the human body lies a crucial point called the "Mysterious Feminine" (Xuanpin, referring to the Dantian or the body’s energy core). Understanding this point means grasping the principles of all things in heaven and earth. This point is not a material entity; the method of cultivation involves forgetting the physical form, eliminating distracting thoughts, and focusing on maintaining inner stillness. Through prolonged practice, when the mind reaches complete tranquility, Yang Qi will naturally arise within the body. As Yang Qi grows, Yin Qi diminishes—this is the principle of "Yang increasing while Yin decreases."

In ancient Hangzhou, I received my master’s transmission of celestial secrets. Not daring to conceal them, I now openly share the essential techniques of cultivation in plain language, hoping that seekers of immortality may encounter them and attain the Dao together. This method is no different from other paths of cultivation.

[Principles of Cultivation]

The great Dao (the Way) is inherently ineffable; it can only be revealed through language. The methods of the Dao have no form; they can only be understood through phenomena. Just as one uses a raft to cross a river but abandons it upon reaching the shore, the original Yang Qi inherited by the human body amounts to 384 zhu (an ancient unit of weight). Of this, 24 zhu are dispersed among the five viscera and six bowels, corresponding to the 24 solar terms, while the remaining 360 zhu correspond to the 360 degrees of the celestial sphere. As Yuanhezi once said: "The human body’s structure mirrors that of heaven and earth." Shao Yong (Master Shao) also remarked: "Who can separate the three powers—heaven, earth, and humanity?" Within each person lies a microcosm of the universe.

Specific Timings for Cultivation:

• During the Zi hour (11 PM–1 AM), the Qi from the two kidneys ascends.
• At the Wu hour (11 AM–1 PM), it reaches the heart, where the two Qi merge and steam, producing fluids from the liver and lungs that descend from the heart.
• The Qi of the left kidney carries the lung fluid downward, while the Qi of the right kidney carries the liver fluid downward.
• By the Hai hour (9–11 PM), they return to the kidneys, with the lung fluid settling in the left kidney.

(Note: The text describes the principles of Neidan (internal alchemy) practice, aligning the human body with the cosmos and refining Yin-Yang Qi through the circulation of energy at specific times.)

Interpretation of the "Wu Xuan Pian" (Treatise on Realizing the Mysteries)

[On Physical Transformation]

When a human being forms in the mother’s womb, it begins with the union of the parents’ vital essence (Jing) and blood, carrying within it a spark of innate Qi (vital energy) as the foundation of life. The embryo develops in this sequence: first the left kidney forms, followed by the right kidney, then the heart, liver, lungs, and spleen, and finally the small and large intestines. Through the physical transformations governed by the Five Phases (Wood, Fire, Earth, Metal, Water), the fetus takes shape after ten months. However, ordinary people only focus on this physical transformation, while Daoist cultivators place greater emphasis on "Qi transformation"—the conversion of innate energy. Many today mistakenly believe the space between the two kidneys is the source of life, or simplistically equate the heart and kidneys to fire and water, or the liver and lungs to the Dragon and Tiger (Neidan terms symbolizing Yin and Yang Qi). These interpretations are not entirely accurate.

[On Qi Transformation]

At ten months in the womb, the fetus’s initial innate Qi ascends to the heart. When this energy reaches the heart, it activates the fetal Qi, causing it to expand outward. This process is like the soul following a spark of spiritual light into the womb amid dark mist. When Yin (material substance) meets Yang (energy), they transform into the Qi of the Taiji (Supreme Ultimate). This Qi rises to the crown of the head, then divides into two descending streams to the left and right kidneys, known as the "Two Modes" (Yin and Yang). Males follow the Dao of Qian (Heaven), while females follow the Dao of Kun (Earth). The interaction of Yin and Yang gives rise to life.

[Essential Teachings on Cultivation]

In ordinary people, innate Qi gradually transforms: liver fluids flow to the right kidney and become blood. If this Qi is excessively depleted over time, leading to exhaustion of Jing and blood, death follows. As the Neidan scriptures state: "The forward movement of the Five Phases is the path of ordinary life (symbolized as a pit of fire), while their reversal (counter-flow cultivation) yields the Seven Treasures (achievements of Daoist practice)." Those seeking immortality must comprehend that "the Dragon emerges from fire, the Tiger arises from water" (referring to the principle of Yin-Yang interaction through reverse cultivation).

Cultivation is divided into Three Passes:

1. Initial Pass: Refining Jing into Qi

2. Middle Pass: Refining Qi into Shen (spirit)

3. Final Pass: Refining Shen to return to Emptiness

Ultimately, one attains "the shattering of the Void" (the highest state). These Three Passes require oral transmission of the heart-method and two months of "bathing" (a Neidan term for the nurturing phase). The subtlety of these esoteric instructions is profound—without guidance from an enlightened master, true accomplishment remains elusive.

(Note: "Bathing" here does not refer to ordinary washing but to a specific stage in Neidan practice where Qi is harmonized and nurtured. "Dragon and Tiger" symbolize the Yin and Yang energies within the body, while the "Three Passes" denote the key stages of internal alchemy.)

The Wu Xuan Pian Explained in Plain Language:

The body's innate primordial Qi (Yuanqi) differentiates into six types of energy ("six offspring"), forming six meridians that spread throughout the body. These meridians circulate continuously, endowing humans with complete life functions and enabling birth into human form. Those seeking immortality must comprehend the origin of their life force, using this understanding as the foundation for cultivating Neidan (internal alchemy, the core practice of Daoist cultivation) to transcend the mundane and attain sagehood. Concerned that written words might be insufficient, I've included diagrams to aid practitioners.

Key cultivation principles:

1. The yang energy stored in the kidneys is called "Kan" (not referring to the physical kidneys)

2. The yin energy stored in the heart is called "Li" (not referring to the physical heart)

Meditation method:

Practitioners need not adhere to fixed schedules. Whenever body and mind are at leisure, find a quiet place to close the eyes and mouth, straighten the ears (focusing hearing), sitting cross-legged or not as preferred. During meditation, achieve: externally forgetting the physical form to transcend material constraints, internally forgetting distracting thoughts to avoid trivial attachments. Maintain awareness that seems both present and absent, both guarded and unguarded—yet never completely empty. With prolonged practice, mental stability will naturally arise, at which point yang energy will manifest within the body.

Yang energy circulation pattern:

Yang energy rises from the coccyx at the waist, ascending along the spine until pausing at the spine-clamping point. Propelled by breath (the "Xun wind"), it continues rising to the crown of the head. When yin and yang energies meet, they transform into sweet saliva descending from the tongue tip to be slowly swallowed into the Dantian (central palace). As alchemical scriptures state: "Breathing works like bellows pumping"—initial stages require effort, while later stages should become spontaneous. Without understanding the principles of Qi's ascent/descent and fire regulation, even daily practice will prove fruitless.

Cultivation warnings:

Excessive fire regulation causes yang energy to rise uncontrollably; excessive water regulation makes yin energy flood downward ceaselessly. One must master balancing methods to harmonize yin-yang. These profound mechanisms require oral transmission from a master—hence the ancient saying: "Immortals refuse explicit explanations," as celestial secrets shouldn't be lightly revealed in writing. Though modern cultivators are numerous, without grasping these essentials, how can one complete the three great stages: "refining essence into Qi, refining Qi into spirit, refining spirit to return to emptiness"?

(Note: Terms like "Kan-Li," "Xun wind," and "three passes" are Neidan terminology representing yin-yang, breath, and key cultivation areas respectively.)

"Interpretation of 'Awakening to the Mysteries'":

True inheritors of the orthodox transmission are exceedingly rare—how could these genuine cultivation secrets be lightly imparted to others?

Regarding "bathing" (a Neidan term referring to restorative phases of fire regulation):

The ten-month embryonic incubation plus two months of bathing complete the full 360-day cycle. Setting aside the ten-month incubation for now, when should these two bathing months be placed? They may occur in the early, late, or middle stages of practice—this is an indispensable part of authentic cultivation that cannot be omitted. Practitioners must comprehend flexibly, not rigidly insisting on positioning them specifically in the mao and you months. The crucial method for embryonic liberation (the advanced stage where the spirit sheds corporeal form) absolutely requires oral transmission from master to disciple.

Concerning the "Mysterious Pass" (the subtle portal connecting human physiology with cosmic forces):

The Mysterious Pass has no fixed form yet permeates all existence. Those who dogmatically assign it a concrete location commit grave error. To situate it outside the heart, liver, spleen, lungs or kidneys is like forcibly creating an acupuncture point in empty space—equally mistaken. Any fixation on specific anatomical positions is fundamentally misguided.

On the "medicinal substances" (Jing, Qi and Shen in Neidan practice):

Essence contains vital energy and blood, while blood harbors true essence. Essence and energy share common origin, just as Taiji generates all phenomena. Never mistake ordinary breathing for the sacred intercourse (of Yin and Yang energies)—the genuine "medicinal substances" transcend life and death.

Regarding "fire phases" (mental regulation during cultivation):

During active firing (intensified concentration), a microcosmic orbit may complete in moments. Across the ten months and three hundred days—comprising 3,600 two-hour periods and 30,000 quarter-hours—one may practice fire regulation by the quarter-hour, by the period, or by the day. Timing requires flexibility, but ignorance of the principles will cause chaotic Qi movement incapable of ascent—here lie oral formulas.

On the "central palace" (the bodily axis of transformation):

Earth generates the myriad beings; the heart governs all affairs. The heart is earth, earth is heart—this is the central Wu-Ji earth (the soil phase in Five Phases theory). The center itself is the Mysterious Pass. Understanding earth's mystery reveals creation's root; comprehending the heart's truth severs all entanglements. How lamentable that contemporary Daoists seek externally rather than turning inward to discover the true Dao!

Concerning "embracing the One" (holding fast to the Great Dao):

After embryonic liberation when the spirit returns to the Dantian, nine more years of worldly cultivation and accumulation of eight hundred virtuous deeds are required for immortal ascension. Then one may roam the cosmic poles, traversing all sacred grottoes—when merit reaches perfection, celestial edicts summon the adept to immortal rank.

On "spirit liberation" (transcendent release of consciousness):

Most cultivators fundamentally misunderstand fire phases, bathing and other crucial methods. Embryonic liberation (the spirit's consummation)...

The Wuxuan Pian elucidates the core secret of Daoist Neidan (internal alchemy) practice—the "Mysterious Pass and Single Aperture" (the body's energetic core). This aperture does not refer to the physical heart but to the abode of the primordial Shen (spirit) that governs the entire body. It is formless and imageless, existing between being and non-being. The key to cultivation lies in maintaining a mind pure and free of selfish desires—the slightest trace of personal craving or distracting thought causes one to lose this state. As the great Song Dynasty Confucian Cheng Yi said, "Only when there is neither deviation nor bias can it be called the Middle Way"—the slightest imbalance renders it incorrect. The Daoist master Shi Xinglin expressed it even more profoundly: the body must grasp the subtle mechanism, while the mind must remain clear and untainted.

This Mysterious Pass and Single Aperture is the root of all things. In motion, it interacts with the external world; in stillness, it nurtures within. During practice, one must stabilize the Shen and allow Qi to flow naturally. The specific method involves guiding internal energies (the White Tiger rising on the left representing kidney Qi, the Azure Dragon emerging on the right representing liver Qi) to converge at the Jiaji acupoint, circulating genuine Qi like bellows stoking a furnace. When the Qi ascends to the crown of the head (Kunlun Peak), Yin and Yang unite (the intercourse of Qian and Kun), transforming into sweet dew that is swallowed from the tip of the tongue and returned to the Dantian (Yellow Palace). Practice this three to four times daily.

The entire process unfolds in three stages:

1) The initial stage requires a hundred days to "establish the foundation," with monthly "ablutions" (purifying body and mind).

2) The middle stage likewise lasts a hundred days, following the same method.

3) The advanced stage of a hundred days demands mastery of "fire timing" (regulating breath and intention).

Completing these three stages enables the practitioner to undergo a radical transformation. If one further persists in nine years of "embracing the One" (single-minded concentration on the Shen), ascension in broad daylight becomes possible. The Great Dao cannot be fully expressed in words—one must relinquish attachment to form, cease deliberate pursuit of lead and mercury (the two Qi of Yin and Yang), and simply abide in the Middle Way. With focused Shen and harmonized breath, the meridians naturally open, and Jing, Qi, and Shen return to their unified origin.

When cultivation reaches the point where body and mind are utterly still, Yang Qi gradually arises within. Once the fire timing is nurtured appropriately, genuine Qi surges straight to the crown (the Silver River passing through the Jade Pillow acupoint), making the top of the head burn as if aflame. The sweet dew produced by the union of Yin and Yang descends from the Mingtang acupoint, generating saliva beneath the tongue that fills the mouth with sweetness. Upon swallowing this nectar, the entire body becomes enveloped in golden light as Jing, Qi, and Shen fuse to form the "infant" (the internal elixir). Through the celestial cycles (symbolized by hexagrams), one practices according to the rhythms of the Northern Dipper. Persisting for a year opens the crown gate (Baihui acupoint); nine years of accomplishment elevate one beyond the ordinary into sagehood, culminating in ascension to the immortal realms astride phoenixes. These are the secret transmission's essential instructions.

"Awakening to the Mysteries" Interpreted:

The essence of cultivation lies in maintaining mental stillness and unified focus (shouyi). One must not wait until the body's vital essences (symbolized by lead and mercury in alchemical terms) dissipate before regretting inaction. Missing the opportune moment may render enlightenment impossible even at life's end. These profound principles should only be transmitted to sincere Daoist practitioners.

On Gathering the Medicinal Essence (a Neidan term referring to collecting bodily essences):

Authentic cultivation involves extracting true Qi from blood, and refining true Jing from Qi. When blood and Qi merge at the crown, they transform into golden nectar (a refined energetic substance). This golden nectar circulates through meridians to become "white blood" (purified energy), ultimately settling in the central palace (Dantian) to form the inner elixir. At the highest level of practice, all bodily fluids transform into pure energy—once the elixir forms completely, one transcends physical constraints to achieve spiritual liberation. The supreme stage surpasses even Yin-Yang principles, yet this still doesn't represent the ultimate wonder.

Essential Foundations:

Practitioners must first locate the "Mysterious Feminine Gate" (key energetic apertures in the body). Maintain awareness of one's fundamental nature while letting go of worldly attachments. Perceive the mysterious pivot (xuan'guan) in the state between presence and absence, without fixating on physical locations.

Experiences of Energetic Circulation:

When bodily passages open, Yin and Yang energies flow naturally in cyclical motion—coming and going unimpeded, allowing perception of heaven and earth's subtlest movements through even the most minute vibrations.

Dispelling Illusions:

When the mind becomes clear as a mirror, a single thought can conjure myriad visions. Practitioners must recognize these as mere illusions, maintaining non-attachment. Just as eyes tolerate no dust, one's fundamental nature should harbor no impurities. While mental fluctuations generate phantoms, abiding in stillness enables natural resonance—freedom from attachment prevents demonic interference.

Countering Obstacles:

When distracted by incessant thoughts and visions, immediately circulate the water and fire energies (Yin-Yang Qi), charging through the Three Passes (critical junctures in cultivation) directly to the inner court (upper Dantian). This disperses the Three Corpses (malicious mental tendencies) and Six Thieves (sensory desires). When encountering mental obscurity, mobilize Yang energy like wielding a sword to deploy formations—using the Three Yang's true fire to dispel Yin pathogens.

Foundation Work:

Buddhists term this stage "forging into seamless unity" (uninterrupted practice). Daoists call it "establishing the foundation"—through sustained regulation of firing times (cultivation rhythms), one ultimately refines the inner elixir. This phase requires day-and-night accumulation of meditative stability, progressing step by step in practice.

Plain Language Interpretation of The Treatise on Mysterious Awakening:

On the Foundation of Cultivation:

The essence of practice lies in maintaining pure intention, with divine light (Shen) protecting the body day and night. The eyes naturally reduce their pursuit of colors, while the heart maintains silent stillness, focused on the profound truth of the Dao.

Key Points of Fire Regulation in Practice:

The eight orifices of the human body correspond to the eight solar terms, mirroring the seasonal changes between heaven and earth. One must grasp the balance of Yin-Yang, much like cinnabar in an alchemical furnace eventually coalescing into purple clouds. Master Bai Yuchan said: For practitioners, each of the twelve double-hours (traditional time units) equals five ke (ancient time measurement), totaling fifteen hundred ke over three hundred days calculated by half-month cycles. The whole body completes a microcosmic orbit in eight ke, with one ke's effort equivalent to a year's cultivation. Understanding this principle allows practitioners to naturally eat when hungry and sleep when tired.

The Meaning of Purification (Muyu):

Internal purification refers to the cyclical regulation of Qi circulation, while mid-month purification denotes the refining process of elixir formation. Zhang Ziyang identified the "Rabbit-Rooster months" (Mao-You months) as optimal for purification, particularly suited for cleansing body and mind.

Essential Practice Methods:

When essence (Jing) and Qi are abundant, the alchemical furnace (the body) maintains warmth. The age of sixteen (two times eight) represents the critical period for foundational consolidation. No deliberate fire regulation is needed—simply maintaining inner purity keeps the Great Dao ever-present. When Qi surges, one should close the mouth and lower the eyelids, preserving clarity and desirelessness while awaiting natural Qi movement. Failure to retain essence causes the elixir to dissipate.

Heightened Caution at Advanced Stages:

This phase differs from ordinary practice—special care must be taken during Qi surges by shutting sensory gates and maintaining Wuwei (non-action).

Signs of Yang Emergence from Utmost Stillness:

When primordial lead (kidney-origin Qi) first appears, immediate collection is required. Timing matters in "herb gathering" (collecting vital energy): too early resembles spring water bubbling up; too late becomes as subtle as ants crawling—neither is suitable.

Specific Practice Techniques:

Close the eyes in contemplation, maintaining a state between emptiness and fullness. When Qi activates from the lower Dantian (Kun Palace), back warmth will be felt. Coordinated with gentle breathing (Xun Wind), Qi ascends directly to the crown. At this moment, retain without leakage, letting Qi transform into sweet dew that gradually descends to nourish the whole body.

Yin-Yang Principles in the Human Body:

The head is where Yang Qi converges, containing Yin essence (true mercury); the five viscera are where Yin Qi gathers, containing Yang energy (true lead). The heart neither ascends to Yang nor descends to Yin—maintaining the Middle Way as the body's sovereign, it governs the whole without form or appearance.

(Note: "True lead" refers to kidney-origin Qi; "true mercury" denotes heart-origin spirit—both core Neidan (internal alchemy) concepts. "Xun Wind" indicates breath regulation; "Kun Palace" signifies the lower Dantian.)

This passage from the Writings on Comprehending the Mysteries discusses the essential principles of Daoist cultivation:

When you hear a certain mysterious sound (referring to special sensations that arise during practice) and investigate it, you will attain resonance and achieve understanding; when you quietly maintain this state, you will enter the realm of "utter stillness without movement." If practitioners can persist in their efforts within this state of "utter stillness without movement," when their skill matures, they will realize that the creative transformations of heaven and earth are already fully present within themselves.

(Note: This describes a cultivation method of achieving unity between heaven and human through inner observation and quiet meditation. "Utter stillness without movement" refers to a state of deep stillness, while "the creative transformations of heaven and earth" denotes the natural order of cosmic operations.)
