《長生詮經》

Interpretation of the Scripture of Longevity

[Section on the Scripture of Clarity and Stillness]

The primordial spirit (Shen) inherently delights in purity, yet is often disturbed by restless thoughts; the heart-mind naturally seeks tranquility, but is constantly pulled by desires. When one releases attachments, the mind spontaneously settles; when consciousness becomes lucid, the primordial spirit shines with clarity. Turning inward to observe the original mind reveals its insubstantial nature; examining the physical form outwardly shows its equally illusory quality; contemplating external phenomena demonstrates the emptiness of all things. Penetrating these three insights leads to the realization of universal emptiness. Progressing further to observe emptiness itself, even the concept of "emptiness" is relinquished, ultimately arriving at a state of luminous stillness—eternal serenity.

[Section on the Yin Convergence Scripture]

Thoughts arise from external stimuli and perish through attachment to them, with the eyes serving as their gateway. Life carries the seed of death, and death nurtures the potential for rebirth. Benevolence may conceal misfortune, while calamity can transform into blessing.

[Section on the Scripture of Ancient Insight]

Apparent movement originates from absolute stillness; purposeful action springs from Wuwei (non-action). Attaining Wuwei allows the primordial spirit to return; with its return, all phenomena settle into quiescence. Maintaining unwavering stillness concentrates the Qi (vital energy), restoring all things to their pre-manifest state. Abandoning visual fixation, inner radiance expands boundlessly; relinquishing auditory discrimination, the mind's wisdom becomes deep and clear. When both faculties of sight and hearing are transcended, the Gate of All Wonders opens. Nourishing the formless essence ensures eternal existence; preserving the shapeless true nature safeguards pristine authenticity. Perfect integration of this true nature grants longevity. Heaven and Earth endure through this principle; humans embodying it attain immortality.

[Section on the Great Pervasion Scripture]

Stillness is intrinsic nature, residing within the heart-mind; movement is the mind's function, containing nature within it. When thoughts arise, original nature recedes; when thoughts cease, true nature manifests—vast and luminous like empty space. The Dao has no form, thus inwardly one clings to nothing; true nature follows Wuwei, thus outwardly no delusions arise. This immutable nature is boundless and limitless. Engaging phenomena without attachment shields against the "six thieves" (senses and intellect); dwelling in the world yet transcending it frees one from karmic bonds.

[Section on Stabilized Contemplation]

Simply extinguish restless thoughts while maintaining mindful awareness; stabilize the void without fixating on it. Whether amid activity or stillness, abide in thought-free equanimity. Discipline without rigidity, relax without dissipation—unperturbed by noise, undisturbed by affairs—this is true meditative stability. Do not invite troubles under pretext of handling them effortlessly, nor seek chaos to test one's composure. Take "non-interference" as the ultimate abode, engaging only as circumstances require. Like a mirror reflecting images without retaining traces, respond spontaneously without residue.

[Section on Embryonic Breathing Scripture]

(Traditional Daoist practice of "embryonic respiration" refers to reverting to the prenatal breathing method, harmonizing breath and intention to achieve union with the Dao through Neidan (internal alchemy). Original text not provided here.)

(Note: Parenthetical pinyin omitted after first occurrences per glossary. Technical terms rendered according to standard Daoist translations.)

Interpretation of the "Scripture of Longevity Cultivation":

On Embryonic Breathing Practice:

The primordial origin of human life (the "embryo") takes form through silent breath regulation, as Qi circulates through the body to sustain vitality. When Shen (consciousness) departs from physical form, death occurs. Understanding the mystery of Shen and Qi leads to longevity—the key lies in maintaining inner emptiness to nourish these energies. When Shen moves, Qi follows; when Shen is still, Qi quiets. To attain longevity, one must achieve perfect fusion between Shen and Qi.

Methods from the "Inscription on Embryonic Breathing":

Practice swallowing saliva thirty-six times daily with gentle, prolonged breaths. Maintain this state whether sitting, lying, walking, or standing, avoiding noisy environments and rich foods. This seemingly simple Embryonic Breathing method forms the foundation of Neidan (internal alchemy) practice. Consistent cultivation not only heals ailments but extends lifespan, ultimately leading to immortal realms.

Daily Practice from the "Supreme Scripture of Daily Cultivation":

Moderate food intake and clear distracting thoughts during meditation. Withdraw visual focus from external sights and auditory attention from sounds, turning inward while maintaining even respiration. Let breathing become so subtle it seems nonexistent—this naturally causes the heart's fire to descend and kidney's water to rise, producing sweet dew (saliva) in the mouth. Thus authentic spirituality inhabits the body, granting longevity.

Essential Practice Principles:

Maintain purity throughout all twelve two-hour periods of the day. Shen (consciousness) is like Qi's child, while Qi acts as Shen's mother. Nurture them inseparably, like a hen incubating her eggs.

Core Teachings from the "Scripture of Heart-Seal":

The supreme elixir consists of the Three Treasures: Jing (essence), Qi, and Shen. During the trance-like meditative state, their fusion can occur within moments. Hundred days of sustained practice yields visible results; twelve years leads to ascension.

On Heart-Breath Relationship in the "Authentic Scripture of Water and Fire":

Desires arise from the heart, while breath follows the heart's calm. This interdependent relationship means regulated breathing naturally pacifies the mind.

Warnings from the "Wenshi Scripture":

Excessive focus on beautiful sights damages vision; overindulgence in fine sounds harms hearing; obsessive pursuit of profound truths injures the spirit. Preserve physical form by storing genuine Qi, achieving invisibility through body-spirit unity. Harmonious breath regulation prevents hunger; nurtured Shen maintains warmth against cold.

Essentials from the "Scripture of Cavernous Numinosity":

Moving tendons and bones perfects the physical form; restraining passions strengthens the spirit; guarded speech preserves blessings. Mastering these three perfections reaches sagehood.

Core Teachings from the "Jade Pivot Scripture":

This passage from the Scripture of Longevity elucidates the core principles of Daoist cultivation:

There are three essential aspects to cultivating the Dao: entering through sincerity, maintaining through stillness, and applying through gentleness. The appearance should be as guileless as foolishness, as quiet as wooden simplicity, and as yielding as clumsy awkwardness. Those who enter understand knowing when to stop; those who maintain understand cautious action; those who apply understand observing the subtle. Perceiving subtleties generates wisdom, exercising caution leads to omniscience, and knowing when to stop brings peace and harmony.

The Chongxu Jing states: Rather than seeking externally, turn inward to contemplate. External seeking chases satisfaction in material things, while inward contemplation finds fulfillment within oneself. The highest form of "wandering" is not knowing where to go; the highest form of "observation" is not knowing what to look at. When spirits meet, they form dreams; when forms interact, they create reality. Thus, those whose spirit is concentrated naturally have no distracting thoughts or delusions.

The Nanhua Jing observes: Mountain trees are felled for their usefulness; fat is rendered for its flammability; cassia trees are cut for their edibility; lacquer trees are wounded for their utility. People all understand the usefulness of "usefulness," but few comprehend the marvel of "uselessness."

The most profound Dao is obscure and unfathomable; the ultimate Dao is silent and wordless. Only by not exhausting the body or disturbing the Jing (essence) can one attain longevity. When eyes see no external objects, ears hear no external sounds, and the mind entertains no external thoughts, the Shen (spirit) guards the form, and the form naturally endures.

The Sanmao Zhenjing explains: Valleys echo sounds because they are empty; the heart resonates with spirits because it is empty; spirits commune with Qi (vital energy) because they are clear and empty; Qi transforms into Jing when it reaches utmost emptiness. At the extreme of emptiness comes clarity; at the peak of clarity comes crystalline purity; transcending the spirit enables transcendence of life and death. Guard Jing internally, generate Qi externally, and use Qi to guide Jing—this leads to longevity.

The Weisheng Jing points out: Jing, Qi, and Shen are the three internal treasures; ears, eyes, and mouth are the three external treasures. Prevent the internal treasures from dissipating with external things, and the external treasures from tempting and disturbing the inner mind.

The Dongshen Jing advises: Being unmoved by favor or disgrace pacifies liver Qi; balancing activity and stillness stabilizes heart Shen; moderating food and drink protects the spleen and stomach; regulating breath and speaking sparingly preserves lung Qi; maintaining tranquility and desirelessness enriches kidney water.

The Yuandao Zhenjing employs metaphors: Plants die when separated from soil; fish perish when removed from water; humans expire when severed from primordial Qi. Therefore, sages regard preserving primordial Qi as the supreme treasure of nurturing life.

Celestial Master Zhang (Zhang Tianshi) of the Han dynasty taught: The Dao of utmost emptiness values Qing-Jing-Xi-Yi (Qing: unstained by worldly dust; Jing: unmoved by restless thoughts; Xi: seeing without looking; Yi: hearing without listening). Practicing these four enables liberation from the cycle of rebirth.

The teachings of Pure Yang Zhenren (Lü Dongbin) emphasize: Cultivating the Dao focuses on internal refinement—harmonizing the relationship between Jing-Qi-Shen and external senses to achieve the wondrous state where form and spirit are both perfected.

Interpretation of the Scripture of Longevity

[Celestial Master Xu Jing Chapter]

Maintaining purity daily brings one closer to the Dao of immortality. When the six spirits (eyes, ears, nose, tongue, body, and mind) are harmonized, natural tranquility arises. The Dantian (lower abdominal energy center) holds its own treasure—there is no need to seek externally. When facing external phenomena, refrain from deluded thoughts—why engage in forced meditation? In nurturing Qi, forget words and guard stillness, subduing the wandering mind. What appears as Wuwei (non-action) is actually a subtle form of action. Between movement and stillness, recognize the source—why seek outside when there is nothing to pursue? The true Dao is often revealed in responding to all things, yet one must not lose themselves in the response. Without losing oneself, the innate nature stabilizes; with stabilized nature, primordial Qi naturally returns; with Qi’s return, the Neidan (internal elixir) naturally coalesces.

Within the body, Yin and Yang (Kan and Li) interact, cycling endlessly until, like spring thunder shaking the earth, a transformation occurs—shedding the mortal shell. When white clouds rise to the crown (Baihui point) and sweet dew (saliva) nourishes the body, one naturally drinks the wine of immortality, entering a realm of carefree transcendence beyond ordinary understanding. Listening silently to the soundless melody, one comprehends the profound mysteries of creation. These twenty lines of truth form the ladder to ascension.

Key Points of Cultivation:

Do not fear the arising of thoughts—only fear delayed awareness. Thoughts are the ailment; non-continuation is the remedy. Maintain steadfast mastery, adapting to circumstances. The mind should be as still as dead ashes, yet vitality must remain lively.

[Perfected Li Chapter]

The great Dao resides within the body. Though all phenomena are empty, innate nature is not. Only when nature is not empty can harmonious Qi be preserved. When Qi returns to the Dantian (Ocean of Origin), life becomes boundless. To prevent the dispersal of the divine spirit within, do not allow random thoughts to linger in the Lingtai (heart-mind). Lingering thoughts obscure the spirit, dissipating true Jing (essence) and harming the bones. When the primordial Shen (spirit) wanders outward, recall it swiftly—when Shen returns to the body, Qi naturally follows. Persist in this practice morning and night, and like an infant forming in the womb, the true elixir will crystallize.

[Three Mao Perfected Lords Chapter]

Breathing Method: With each inhale, draw Qi to the navel. With each lift, swallow, allowing water and fire (heart and kidneys) to unite.

[Hanshanzi Chapter]

The Lingtai (heart-mind) should be as clear as an ice jar, reserved only for the dwelling of the primordial Shen. If even a trace of stray thought remains, how can one align with the pure and empty great Dao?

[Perfected Yuxu Chapter]

Essentials of Nourishing Life:

In winter mornings, avoid fasting; in summer nights, avoid overeating. Rise early, but not before the rooster crows; retire late, but not after sunrise. When the inner mind is lucid, the true person (primordial Shen) dwells peacefully; when Qi is settled, malevolent influences stay far away.

[Perfected Zhonghuang Chapter]

All things are inherently empty—mind and form are equally insubstantial. Understanding this leads to awakening, yet the awakened transcend names and forms. Within emptiness lies wondrous existence; within existence appears true emptiness. Serene and unattached, innate nature remains eternally complete.

Cultivation Formula:

The Heavenly Gate (Baihui point) should always remain open; the Earthly Door (perineum) should always remain closed. Breathing should be continuous and subtle—inhaling deeply to the heels, exhaling fully to the crown. This is called "the mutual nurturing of Shen and Qi as mother and child," requiring the focused endurance of a hen brooding over her eggs.

Interpretation of the Scripture on Longevity

[Ma Danyang Chapter]

Cultivating the Dao requires no forced effort—simply diminish worldly thoughts each day. Only by reaching a state of self-forgetting and nature-forgetting can one truly enter the natural condition of "no cultivation, no attainment." Refining Qi (vital energy) should be as effortless as daily life, harmonizing the Yin-Yang (symbolized by the Dragon and Tiger) within the body, and never allowing the "monkey-mind" (restless thoughts) to disturb practice. When the heart-mind settles, desires naturally fade; when the body becomes empty, true Qi flows freely; when worldly thoughts cease, the Shen (spirit) becomes vibrant; when Yang Qi flourishes, Yin Qi naturally weakens.

[Secret Treatise on the Mysterious Pass Chapter]

To cultivate the heart, one must resolve to become an immortal of longevity; to refine one’s nature, one must transcend like the "living dead." If the mind is stirred by external affairs, it is like fire burning within—shaking the very essence of life. Thus, stillness of wandering thoughts nurtures Qi, while regulating the breath pacifies distractions. Non-attachment to external things brings inner purity; a tranquil heart gives rise to wisdom, while an agitated heart breeds confusion.

[Hao Taigu Chapter]

Those swayed by their environment remain ordinary; those who transcend it become immortals. Cultivate Qi in stillness, temper the Shen amid noise.

[Wang Qiyun Chapter]

To stabilize the heart-mind, one must act contrary to the world: what others chase, I do not crave; what others pursue, I do not follow. Thus, worldly temptations cannot shake you, and you naturally attain clarity, freeing yourself from the bonds of Yin-Yang. Suppressing desires only strengthens attachment—better to release deluded thoughts entirely, revealing the true self.

[Bai Yuchan Chapter]

The essence of the Great Dao is no-mind and no-thought; its expression is wordless and silent; its foundation is gentleness and humility; its basis is purity and Wuwei (non-action). Light nourishment sustains Qi; abandoning anger nurtures nature; humility in conduct cultivates De (virtue); maintaining stillness refines the Dao.

The true fire (Neidan term for life-force) of cultivation knows no fixed hour; the spiritual medicine (Jing-Qi) needs no measurement. For the Shen is the fire, and the Qi is the medicine—refining Qi with Shen coalesces the inner elixir. The so-called Golden Elixir is forged by gathering the two Qi of Yin-Yang (the "two eights" signify balance), tempered over time (the "three hundred days" symbolize a complete cycle). The key lies not in superficial techniques (such as swallowing saliva) but in consolidating primordial energy—guided by oral instructions. In truth, the method is supremely simple: nurturing the root of life (symbolized by the infant, representing pure Yang) within emptiness, refining Yang from Yin (the "Golden Lord" signifies lead, representing original essence).

This scripture describes the profound states of Daoist Neidan (internal alchemy) cultivation:

The cultivation process involves harmonizing the "living tiger" (symbolizing the original spirit, Shen) with the "charming maiden" (yin energy), while the "crimson dragon" (yang energy) serves as the guiding force. Through the union of Yin-Yang (represented as the celestial husband and earthly wife), the Golden Elixir (Jindan) is produced. This resembles how the "yellow matron" (the mediating earth element in the spleen's Dantian) reconciles the "fire maiden" (heart's fire) with the "water youth" (kidney's water), ultimately forming the "red infant" (the perfected elixir). During this alchemical process, the furnace fire burns intensely, capable of refining even emptiness itself.

The achieved state manifests when "spirit returns to the four elements" (Shen merging with earth, water, fire, and wind), visualized as the entwined turtle and snake (symbolizing the Black Tortoise constellation). At this stage, Qi circulates freely through the limbs while "golden liquid" (the elixir's nectar) emerges within, blossoming like jade-white flowers upon golden lotuses. Practitioners enter a realm transcending self and object, directly experiencing nature's sublime beauty.

Enlightenment brings the realization of "great death and great rebirth" - liberation from the cycles of samsara. One awakens to the fundamental truth of existence ("discovering father was always the source"), gradually clarifying the path forward. Cultivation requires unwavering focus, mirroring a dragon nurturing its pearl or a hen incubating its egg.

The Golden Elixir functions like a luminous pearl illuminating all realms. It represents both the "ninefold cycled supreme elixir" (highest alchemical achievement) and the "elixir of immortality". In this state, all phenomena unite - even "the lipless stone maiden" and "lame wooden man" (symbols of imperfection) reveal miraculous powers.

Essential principles emphasize avoiding external attachments while realizing the "primordial foundation" (the fundamental Dao) through serene stillness. Natural metaphors - the cuckoo crying in rain, the begonia listening to wind - subtly illustrate how cultivation must follow nature's inherent patterns.

[Note: Specialized terms include "black crow and jade rabbit" (sun and moon), "turtle-snake" (northern Black Tortoise constellation), "white tiger" and "azure dragon" (western and eastern celestial animals), and "mercury-lead" (symbolizing yin-yang energies) - all crucial symbols in Neidan practice.]

Interpretation of the Scripture of Longevity:

Master Sima’s Teachings:

To cultivate the true Dao (the Way), one must first eliminate wicked thoughts, sever external disturbances, and maintain inner purity. Then, through introspection, one should immediately dispel any arising distractions. Practice must be continuous, day and night—only by removing restless thoughts while preserving the awakened mind can one progress. Maintain a state of emptiness without clinging to the concept of "void," and refrain from rigidly adhering to methods while staying true to one’s nature. This profound practice yields profound benefits.

(Key Principles of Cultivation):

Silence nurtures Qi (vital energy); fewer distractions sharpen wisdom; freedom from anger harmonizes the hundred spirits; absence of vexation cools the heart. Avoid greed, flattery, arrogance, and stubbornness—remain flexible and open. Non-greed is true wealth; a clear conscience fears no authority. When desires cease, the spiritual spring flows naturally; when Qi settles, true breath becomes long and steady. Excessive engagement with the external world depletes the body; scattered thoughts disperse the Shen (spirit). Only by reducing desires can the primordial Shen be awakened; only when the soul is strong can one penetrate the mysteries of all things. A true practitioner attains the state of "sitting in oblivion" (zuowang), where eating and drinking cease, and the boundary between self and world dissolves.

Master Sun’s Teachings:

Among heaven and earth, humans are most precious—the head symbolizes heaven, the feet symbolize earth, and one must cherish the body given by one’s parents. Of the Hongfan’s nine principles, the foremost is the path to longevity, and the key to nurturing life lies in the "Three Abstinences": abstain from great anger, great desire, and great drunkenness. Failing to observe these three will deplete the primordial Qi.

(Essentials of Life Nourishment):

To seek longevity, one must abstain from violent temper. When the heart’s fire does not flare, the spirit remains tranquil. Just as wood untouched by fire avoids turning to ash, so too can one prolong life by abstaining from rage. Boundless desires exhaust Jing (essence); overuse of the mind depletes the primordial Shen; excessive labor dissipates harmonious Qi. Anger harms Qi; excessive contemplation damages the spirit. A weary spirit is easily ensnared by external things; weakened Qi invites illness. Avoid extreme emotions, practice dietary moderation, and especially abstain from nighttime drunkenness and resentment. At the hour of Hai (9–11 PM), sit quietly to regulate breath; at the hour of Yin (3–5 AM), rinse and swallow the "jade nectar" (saliva). This keeps pathogenic influences at bay and ensures the natural abundance of Jing and Qi. The secret to avoiding all ailments lies in moderation.

(Note: The "Nine Principles of the Hongfan" refer to the nine governance laws recorded in the Book of Documents; "sitting in oblivion" (zuowang) is a Daoist state of forgetting self and world; "striking the cloud drum" and "rinsing the jade nectar" refer to specific life-nourishing techniques.)

Interpretation of the Scripture of Longevity:

The essentials of nurturing life and cultivation:

While pungent foods like onions and garlic can calm the spirit and bring joy, it is even more vital to cherish one's vital Qi (energy) and maintain inner harmony to prolong life. The foundation of cultivation lies in whether one can follow these principles—even ordinary people can attain the state of a true immortal (Zhenren).

Immortal Cao’s Insights on Cultivation:

"Shen (spirit) represents the original source of human consciousness, while Qi (vital energy) is the root of life. When the spirit does not scatter outward, the breath naturally stabilizes. These two are fundamentally one—if this foundation is lost, cultivation has no basis."

Poetic Verse by Patriarch Wang Chongyang:

"Let go of cleverness and cunning, return to simplicity and the state of Wuwei (non-action), and in doing so, one can accomplish all things. Turn a deaf ear to worldly clamor, let your steps follow the heart, and the spirit and breath will always remain in harmony. In moments when the body feels as if in a drunken haze, one might ask the heavens: Who is the true self?"

Cultivation is Like Tuning a Zither or Forging a Sword:

Refining the mind is like tuning a zither—too tight, and the string snaps; too loose, and it won’t sound. Only with balanced tension can harmony arise. It is also like forging a sword: steel that is too hard shatters, while tin that is too soft bends. Only by uniting firmness and flexibility can a fine blade be made.

Transcending the Three Realms of Existence:

The Realm of Desire, the Realm of Form, and the Formless Realm—to surpass them, one must: forget distracting thoughts to rise above the Realm of Desire, release attachment to appearances to transcend the Realm of Form, and avoid clinging to emptiness to go beyond the Formless Realm. Only then can one reach the sacred realm of immortals and return to the pure, empty nature of the Dao.

Li Jing’an’s Essential Teachings on Refinement:

"When the mind is empty and still, and body and spirit enter the state of Wuwei (non-action), forgetting both movement and stillness, merging inner and outer, then naturally the stages of cultivation unfold—Jing (essence) transforms into Qi, Qi transforms into Shen (spirit), and Shen returns to emptiness."

The State of the Unattached True Immortal:

"The heart-mind is pure and tranquil, thoughts upright, spirit and breath intermingling, Yin and Yang energies uniting in the Dantian (energy center). Facing external phenomena without stirring delusions, the breath returns to its root, and the myriad spirits return to their places. This deep, serene, and enduring state is the true work of cultivation."

Shi Xinglin’s Alchemical Verse:

"All things in the world are born and die, yet only the Yuanshen (primordial spirit) can perish and be reborn. When the spirit is anchored in the breath, the Golden Elixir (Jindan) is naturally achieved. When the mind is like a cloudless sky, and in the deep night the moon shines bright, one hears the spring birds sing—the awakening of life."

Shi Jianwu’s Secrets of Longevity:

"Breath is the medicine for prolonging life, and the heart-mind is the master that guides the breath. One who understands how to regulate breath can become a realized immortal."

Zhang Ziyang’s Method of Harmonizing the Four Symbols:

"Withdraw the gaze, stabilize the hearing, regulate the breath, and still the tongue—when these four methods are coordinated, it is called 'Harmonizing the Four Symbols,' a crucial foundation for cultivation."

This scripture elucidates the essential methods of Daoist Neidan (internal alchemy) cultivation, which can be divided into several key aspects:

1. The Method of Five Qi Returning to Origin:

When the eyes refrain from seeing, the Hun (ethereal soul) returns to the liver. When the ears cease listening, the Jing (vital essence) returns to the kidneys. When the tongue abstains from tasting, the Shen (spirit) settles in the heart. When the nose stops smelling, the Po (corporeal soul) withdraws to the lungs. When limbs remain still, intention gathers in the spleen. This achieves the state of "Five Qi Returning to Origin" (the convergence of vital energies from the five organs), where essence transforms into primordial Qi, Qi refines into spirit, and spirit merges with emptiness—culminating in the "Three Flowers Gathering at the Crown" (the unification of essence, Qi, and spirit).

2. Descriptions of Meditative States:

In profound stillness, practitioners may experience "white snow" (pure Yang Qi) and "yellow sprouts" (primordial essence) manifesting within. The Dantian (jade furnace) maintains gentle warmth while purple auroras appear at the crown (Muddy Pellet Palace). Advanced practitioners witness golden lotuses blooming in sacred waters, moonlight clear as a mirror, with body and mind becoming as luminous as heaven and earth.

3. Dragon-Tiger Union:

This metaphor describes the harmonious interaction of Yin-Yang energies (dragon representing Yang, tiger symbolizing Yin) within the Dantian, ultimately forming the "marrow of heaven and earth" (Golden Elixir). The essence lies in holding fast to the "One" (the origin of Dao), maintaining a mind as serene and spotless as the full moon.

4. Breath Regulation Essentials:

Practitioners stabilize the heart-mind while directing inner vision from the nose tip to the navel, guiding the heart fire (conscious intention) downward to the Qi sea (Dantian). Breathing should resemble spring fish moving gently or winter insects in quiet hibernation—soft, continuous, and naturally synchronized with bodily rhythms. Through this method, one masters the alchemical fire (alternating civil and martial fires) and timing (medicine maturation).

5. Emotional Influences:

The text warns that grief, anger, and other emotions disrupt Qi-blood circulation, causing illness. Practitioners must temper emotions to maintain equanimity, thereby accessing the primordial Qi of heaven and earth.

Integrating insights from various masters (including the Ocean Daoist, Zhu Xi, and Tan Jingsheng), this scripture systematically presents core principles and practical techniques of Neidan cultivation.

The Scripture of Longevity Interpretation expounds the core principles of Daoist cultivation:

Regarding fundamental cultivation methods:

The practitioner must first gather the wandering mind, safeguarding the primordial spirit (Shen) like a treasured pearl in a pouch—withdrawing brilliance to nurture hidden virtue. The inner state should become as still as unhewn stone, yet as precious as a jewel repository. Cultivation progresses through three stages: first forgetting the physical form to nourish Qi, then forgetting the breath to nourish Shen, and ultimately forgetting spiritual consciousness to merge with emptiness. This practice of "forgetting" holds the key to attaining the realm of non-being, echoing the Sixth Patriarch Huineng's enlightenment verse: "Originally there exists not a single thing—where could any dust alight?"

Wei Boyang's supplementation identifies three crucial bodily apertures: the ears as the essence gate (Jing) prone to leakage, the eyes as the spirit gate (Shen) susceptible to dissipation, and the mouth as the Qi gate vulnerable to depletion. When ears chase sounds, eyes crave beauty, and the mouth engages in idle speech, the Three Treasures (Jing-Qi-Shen) scatter. True practitioners must vigilantly guard these portals.

Chen Xubai observes that modern people suffer from essence (Jing) draining downward and primordial Qi (Yuanqi) evaporating upward, creating disharmony between water (Kidney) and fire (Heart). This stems entirely from chaotic mental activity. When greed ceases, essence no longer descends; when anger dissolves, Qi no longer ascends. Only through complete mental purification can water and fire naturally unite.

Essential alchemical principles reveal:

1. Shen, Qi and Jing constitute the supreme medicinal ingredients. The transformative process follows: refining Jing into Qi → refining Qi into Shen → refining Shen to merge with Dao—known as the mystical "Seven Returns and Nine Reversions" method.

2. Internal alchemy (Neidan) involves five critical elements: the medicinal source (Dantian region), harvesting timing (during deep meditation), refinement technique (single-minded concentration), medicinal fusion (primordial Qi activation), and fire regulation (maintaining wordless awareness).

3. The priceless "rootless spiritual herb" (primordial Qi) actually dwells within our heart-mind—no external search is necessary.

Note: "Yellow Court" (Huangting) refers to the Dantian energy center region. "Seven Returns and Nine Reversions" denotes the alchemical process of cyclical refinement where essence and energy ascend through bodily channels.

This scripture elucidates the essential techniques of Daoist Neidan (internal alchemy) cultivation, which primarily consists of three phases: preparing the medicinal ingredients, refining the medicine, and controlling the firing process.

[Medicine Preparation Stage]

During practice, maintain a mind free of distractions, focusing attention on the Dantian (energy center, known as the "regulating center"). Sustain long, unbroken breathing rhythms. Whether walking, sitting, or reclining, preserve this state of focused awareness. The medicinal ingredients (referring to the body's Jing-essence and Qi-energy) must remain pure, with the key lying in continuous refinement through the fire of breath (Qi refinement). This is akin to maintaining ideal temperature in the golden cauldron (the Dantian) and ensuring the jade furnace (the body) remains neither too hot nor too cold.

[Refinement Essentials]

When gathering the medicinal ingredients, be mindful that the medicine contains fire (Yang energy); when refining the medicine, note that the fire contains medicine (Yin essence). Mastering this principle of Yin-Yang transformation allows the natural formation of the elixir during meditative absorption. Ancient masters taught that medicinal ingredients embody Yang containing Yin, while the firing process embodies Yin containing Yang. Understanding this principle enables perfect fusion of fire and medicine.

[Firing Control]

Guide the Qi-energy with intention, allowing the breath to flow naturally. Maintain physical and mental suppleness, gradually accumulating energy like a pregnant woman nurturing a fetus or a dragon cultivating its pearl. Practice should balance movement and stillness—neither overbearing intention (which causes excessive fire) nor scattered focus (which causes insufficient fire). Preserve moderation, allowing Shen-spirit and Qi-energy to harmonize. This is the secret to sustained alchemical practice.

[Special Reminder]

Authentic cultivation disregards specific hours (such as midnight or noon) or auspicious days (like new moons or full moons). The profound meaning behind sages transmitting the medicinal ingredients but not the firing techniques lies precisely in this principle.

[Supplementary Verse by Qiu Changchun]

Just as clear skies should bear no dark clouds, practitioners must maintain luminous clarity of mind. If distracting thoughts (dark clouds) arise, the entire body becomes unsettled. Use the wind of wisdom (awareness-power) to disperse the mist, allowing the bright moon of original nature to manifest naturally. Upon achieving success in cultivation, one attains the carefree liberation of immortals—unfettered by honor or disgrace, transcending worldly attachments.

Notes:

1. Golden Cauldron and Jade Furnace: Neidan terminology—the golden cauldron refers to the lower Dantian, while the jade furnace signifies the entire body.

2. Celestial Cycle: The pathway of Qi circulation within the body during Neidan practice.

3. Wind of Wisdom: A metaphor for the illuminating power that dispels distracting thoughts.

4. Nine Orifices and Hundred Bones: Refers to all bodily apertures and skeletal structures, representing the entire physical form.

Interpretation of the Scripture of Longevity Elucidation

Master Cuixuan’s Chapter:

1. This Song of Spring speaks of the natural Dao, effortless like a flute without holes or a zither without strings. Upon awakening to the Dao, one suddenly realizes life is but a dream—yet day and night, the pure and wondrous sound of the Dao fills heaven and earth.

2. Key points of cultivation:

• True Lead (Primordial Qi): The breath should be steady, without fluctuation, until the qi is completely tranquil. If even a trace of instability remains, the physical form cannot be preserved, and the primordial qi will scatter, returning to the realm of Yin.
• True Mercury (Primordial Spirit): The mind must be pure, free of distracting thoughts, until the spirit is utterly concentrated. If even a hint of impurity lingers, the spirit will not be purely Yang and may fall into the path of ghosts.

3. Refining qi and preserving the spirit will be futile if done incorrectly. The true secret of the elixir lies in contemplating the realm of emptiness throughout the day. The Jade Nectar (saliva) nourishes the heart-mind, while the Golden Embryo (Golden Elixir) condenses in the sea of qi. One need only seek the "medicinal ingredients" within the body—there is no need to rigidly study alchemical texts. The Fire Dates (heart fire) and Intertwined Pears (kidney water) have no tangible form. Spend the day regulating the fire phases (cultivation rhythm), using the Divine Water (essence-qi) to nourish the Golden Flower (Golden Elixir).

4. When spirit and qi return to the Dantian (root), body and mind revert to their origin—this profound pivot is known to few. It is like the moment when all sounds arise under the full moon over countless mountains, seizing the opportunity to circulate the Heavenly Cycle (qi flowing through the meridians). The poetic vision of crabapples reflecting moonlight or willows swaying in spring breeze can only be verified in the vastness of emptiness.

Master Zixia’s Chapter:

The Golden Elixir is merely a tool for seeking the Dao—once the Dao is attained, the tool is discarded. When one realizes the realm of emptiness, even the concept of Wuwei (non-action) must be shattered. The spiritual light shines eternally, embracing all things. Responding to circumstances while maintaining purity, nine years of cultivation can forge an indestructible diamond body.

Master Baoyi’s Chapter:

The essentials of cultivation:

• Ears not listening recklessly: The Kidney Water (Kan trigram) naturally clarifies.
• Eyes not gazing carelessly: The Heart Fire (Li trigram) naturally turns inward.
• Mouth not speaking idly: The Lung Metal (Dui trigram) naturally quiets.

When these three are sealed, the true nature spontaneously manifests.

Master Chen Niwan’s Chapter:

Immortal cultivation is divided into three grades, and elixir refinement has three levels of success:

• Superior Elixir Method: The body serves as the Lead (vessel), the mind as the Mercury (ruler), stillness as Water, and wisdom as Fire. The elixir embryo can form in an instant.
• Middle Elixir Method: Qi serves as the Lead, spirit as the Mercury, the noon hour (fire phase) as Fire, and the midnight hour (water phase) as Water. The elixir image takes a hundred days to complete.
• Inferior Elixir Method: Essence serves as the Lead, blood as the Mercury, kidney water as the foundation, and heart fire as the catalyst. Success requires a full year.

Master Li Daochun’s Chapter: Note: Parenthetical terms explain internal alchemy (Neidan) concepts, such as "Lead and Mercury" (fundamental elements of cultivation), "Heavenly Cycle" (the circulation path of internal qi), and "fire phases" (the intensity and rhythm of meditative focus during practice).

Interpretation of the "Scripture of Longevity" in Plain Language:

The key to cultivating the Golden Elixir (Jindan) lies in obtaining True Lead (original essence) and True Mercury (original spirit), yet one must not pursue them through forceful striving. Clinging to deliberate methods ultimately becomes a burden; only by maintaining non-seeking and non-attachment can one attain true freedom. By constantly preserving a clear and tranquil mind, the luminous pearl of one's original nature will naturally manifest. When external distractions and cunning calculations are forgotten, the true treasure of life achieves perfection. Whether in movement or stillness, one remains unobstructed—wherever the original mind abides is the realm of immortals.

In refining the great medicine within the Three Dantian (upper, middle, and lower energy centers), fixation on intention only creates bondage. Regulating the breath must reach the state of True Breath (natural respiration), while refining the spirit must enter the "spirit of no-spirit" (consciousness beyond thought). When the distinction between self and objects is utterly forgotten, the Three Flowers (Jing, Qi, Shen) spontaneously coalesce; when scheming minds are decisively relinquished, the Five Qi (energies of the five organs) naturally harmonize. Upon reaching the state where all directions are open and connected, the Complete Perfection (Quanzhen) Dao manifests effortlessly in every moment.

Excessive pursuit of intelligence and wisdom only breeds vexation—simplicity and genuineness are far superior. Lofty rhetoric pales beside silence; severing discursive thoughts naturally distances one from disputes. Withdrawing one's radiance and distancing from sensory pleasures, a single thought of clarity dissolves ten thousand concerns. A close reading of the Three Teachings' classics reveals that the character "息" (rest, breath) is most crucial: Buddhists rely on breath regulation and introspection to attain Zen realization; Confucians quell deluded thoughts to comprehend heavenly principle; Daoists refine the spirit through breath modulation. These three approaches to breath regulation complement one another.

Tianlaizi's Poetic Explanation:

To fish for the moon in the North Sea (primordial Qi), first gather the floating clouds of South Mountain (postnatal distractions). Understanding this principle, one may ride a crane to meet the Primordial Sovereign (original spirit). When the moon sets in the west, pursuit proves futile—yet the True Yang (symbolized by the ox) actually revolves inverted within the Moon Palace (Dantian).

The Mysterious Feminine Gate (Dantian) remains ever open; the spiritual aperture at its center is perfectly natural. Without mechanical locks, the sun and moon (Yin and Yang energies) come and go freely therein. Harvesting the medicinal herbs (gathering primordial Qi) requires understanding lunar phases; cultivation must discern gold within water (True Yang within Kan). If the moon lacks its Geng position (waxing phase) or gold loses its watery nature (incomplete Kan trigram), even True Lead becomes meaningless labor.

Wu Mengzi's Poetic Metaphor:

The body resembles a carriage, the heart its axle—when the carriage moves, the axle spins without cease. The fruits of immortality (pear and jujube) originally dwell within one's own heart, yet remain unseen due to unremoved thorns (distracting thoughts). The relationship between body and mind resembles guest following host—when the host (mind) is tranquil, the guest (body) naturally finds peace; otherwise, the spirit scatters.

Long Meizi's Poetic Revelation:

Before the separation of chaos into Supreme Ultimate (Taiji), the wind-wheel (Qi mechanism) rotates to produce True Lead. Stillness reaching its extreme spontaneously generates movement; form emerges from formlessness. The One Qi (primordial energy) is fundamentally born of emptiness.

Interpretation of the Scripture of Longevity Elucidation

[The Movement of the Two Polarities (Yin-Yang)]

The cyclical transformations of heaven and earth, Yin and Yang, all originate from an inner state of stillness. The endless cycle of birth and change in all things ultimately manifests as the hidden paradise (the inner landscape of the human body).

[Essential Teachings of Alchemy (Neidan)]

Master Zixu Liaozhen (a Daoist adept) explains: Heaven and earth move like a bellows, following a rhythmic pattern, and the moment when Fire (Li) and Water (Kan) intersect must be precisely grasped. Lead (the primordial Qi of the kidneys) rises like a dragon, while Mercury (the spirit of the heart) descends like a tiger. The tortoise (Yin) and the serpent (Yang) meet above and below. The sun in the heavens turns beneath the earth, while the lunar essence (Jing-Qi) from the ocean’s depths (the lower Dantian) ascends upward.

[The Key to Cultivation]

Heaven, earth, the sun, and the moon do not move on their own—they are regulated by the Big Dipper (symbolizing the body’s central axis). When the human heart aligns with the Dao, the reversal of Yin and Yang happens in an instant. Once the battle between dragon and tiger (Water and Fire) subsides, the three Dantian (upper, middle, and lower energy centers) return to stillness. It is then that the Mysterious Pearl (the inner elixir) can be gathered and planted in the Dantian. The Yellow Matron (the mediating force of the spleen-earth) harmonizes as the matchmaker, uniting the Infant (the spirit, Shen) and the Maiden (the vital essence, Jing). Daily practice must align with the celestial timing, subtly resonating with the movements of the stars.

[The True Meaning of Guarding the One (Shou Yi)]

Yingchanzi (a practitioner) reveals: By holding fast to the Primordial Qi (the original energy), one penetrates the profound. Only through single-minded purity can the teachings of the sages be understood. The Supreme Mystery of the True One (the source of the Dao) is the key to returning to the essence of life—the "One" is the eternal Dao. Do not assume that attaining the "One" means all is accomplished; after attaining it, one must still preserve it without loss. Penetrating the "One" allows comprehension of heavenly principle—the convergence of all methods into one is not miraculous.

[The Distinction Between Being and Non-Being]

In the beginning, the "One" gave birth to all things; only through the mutual dependence of being and non-being can things endure. Only by truly reaching the state where all existence returns to the "One" can one simultaneously perceive both sides of reality. After attaining the "One," one must also forget the "One" to wander freely with creation. Clinging stubbornly to the "One" is like a foolish cat guarding an empty hole. When the Five Phases (Wood, Fire, Earth, Metal, Water) blend and return to the Great Void (Taixu), even the Great Void itself must be transcended.

[A Warning for Practitioners]

Modern people mistake "non-being" for dull emptiness (a misunderstanding of true emptiness) and regard the "One" as rigid asceticism. If one truly comprehends the principle of "guarding the One while knowing non-being," they can transcend the duality of "being" and "non-being." The subtleties of daily practice are profound and difficult for ordinary people to grasp fully. Maintain virtuous thoughts and discard empty theories. The myriad methods are not illusory—obsessively transmitting them only breeds delusion. Without planting good causes, how can blessings arise? Without accumulation, how can loss occur?

[Wisdom for Living]

Regard joy and anger, sorrow and happiness with detachment—why worry over hardship? Without creating good causes, how would bad karma form? Shatter the distinction between self and others, and leap beyond disputes of right and wrong. There is no need to calculate this life or the next—simply cultivate genuine practice in the present moment.

Interpretation of the "Scripture of Long Life"

Returning to one's original purity by letting go of distracting thoughts—since before birth there were no worldly attachments, why worry about the torment of karmic fires? Neither "being" nor "non-being" should be clung to; emptiness and substance naturally connect. Forget the traces of coming and going—what does life and death matter? When hungry, eat a bowl of rice; when thirsty, drink half a pot of spring water. When in good spirits, amuse yourself; when tired, lie down and rest. Those who understand this truth need not seek mysterious principles beyond the world—the clarity of present life is evident, and the ultimate state will naturally shine forth.

Daoyin Practice (Ancient Health-Preserving Techniques):

Close your eyes and sit quietly, adopting the "holding firm" gesture (thumb pressing the base of the ring finger) to focus the spirit. Tap the teeth 36 times, cup the head with both hands ("Kunlun" refers to the head), and perform the "Heavenly Drum" exercise (covering the ears and flicking the fingers) 24 times on each side. Gently rotate the neck to loosen the vertebrae, stir the saliva with the tongue, rinse the mouth 36 times, and when the mouth is full of saliva, swallow it in three portions. Hold the breath, rub the hands until warm, and massage the lower back ("Jingmen" refers to the kidney acupoints), visualizing heat at the navel. Rotate the shoulders like a pulley, stretch the legs, lift the hands as if supporting the sky, and bend to touch the toes. Wait for saliva to regenerate, then swallow it three more times. After completing this routine, the Qi and blood will flow smoothly within the body. The true Qi circulates throughout ("River Cart" refers to the microcosmic orbit), keeping harmful influences at bay, ensuring peaceful sleep, immunity to heat and cold, and resistance to illness. The best times to practice are during the Zi period (11 PM–1 AM) or Wu period (11 AM–1 PM), aligning with the rhythms of heaven and earth.

Du Daojian's Essential Teachings on Cultivation:

The Great Dao is actually very close, right before your eyes. Grasp the profound workings of heaven and earth to refine yourself into an immortal. The most wondrous method is to gather the spirit and wait in stillness, as if something is there yet not there. Like the Yellow Emperor seeking the Mysterious Pearl (a metaphor for the Dao), he ultimately attained it only when his mind was free of intention. This truth can only be inwardly realized, not conveyed in words. In the deepest stillness, subtle transformations naturally arise, like swirling mist and clouds. The dragon's roar and tiger's cry (symbolizing Yin and Yang Qi) converge; at the right moment, "gather the medicine" (harvesting the innate Qi) and refine it with proper fire control. Guard the Dantian ("Southern Palace" refers to the heart fire) and seal the spirit, like Nüwa smelting the five-colored stones to mend the heavens. Forming the elixir takes but a moment, yet its nurturing requires a full year—like a hen brooding over eggs, relinquishing all distracting thoughts. Circulate the microcosmic orbit ("Heavenly Root and Moon Cavern" refer to the Governing and Conception Vessels), allowing the true Qi to flow through the three Dantians. Persist in practice without counting gains or losses, progressing step by step like piling earth to form a mountain.

Interpretation of the Scripture of Longevity

Master Xu’s Teachings:

Cultivation is like building a high tower—it requires steady accumulation. The right moment is rare and must not be missed. Act swiftly; do not wait until your hair turns white to regret. If the meridians (key passages) remain blocked, sitting in meditation is futile—like grinding a mill without grain. Only when the meridians are cleared and obstructions dissolved can one circulate the essence and Qi (the "three vehicles"), allowing the kidney water (true water) and heart fire (true fire) to merge, with energy rising from the soles of the feet (Yongquan) to the crown of the head (Niwan Palace). If the meridians are not yet open, reckless effort is pointless—how can one refine the elixir (lead and mercury) when even one’s own life remains unstable? Every person has three crucial gateways (the "three passes"), but opening the crown of the head (the "top gate") is the foundation of practice. Frequently swallow the saliva (the "divine water of Hua Pool"), draw the heart fire (the "Primordial Lord of the Purple Mansion") downward, and let the breath flow through the joints. In this way, essence and Qi will flourish, and the spirit (Shen) will stabilize naturally.

Master Xue’s Teachings:

Cultivation requires working in reverse: first harmonize water and fire (Kan and Li). Repeatedly swallow the jade-like saliva (Yu Ye) and circulate the essence from the kidneys (the "golden essence behind the elbow"). The profound mystery lies in this transformation of Yin and Yang. Attaining this "divine elixir" grants longevity. Master the secret of guarding the Dantian (the "valley pass"), and you may become an immortal who never ages.

Master Xiaoyao’s Teachings:

In the womb (before the parents gave birth), a child cannot speak for ten months yet breathes naturally—this prenatal state holds profound secrets. After birth, when the umbilical cord is cut, the innate spark of spiritual awareness (true lead) hides within the Dantian (true earth). Always rein in wandering thoughts (the "mind-monkey and thought-horse"), or you will be lost in the cycle of rebirth. With a true master’s guidance, results can appear in just twenty days. Stabilize the Dantian, return the breath to its root, and gather spirit and Qi—this is genuine skill. Preserving life begins here; do not waste your days in vain.

Essentials of Life Preservation:

The eyes are the windows of the spirit (Shen); the nose is the gateway of Qi; the coccyx (Weilü) is the passage of essence. Overusing the eyes depletes the spirit, disordered breathing harms Qi, and excessive desire damages essence. The key to preserving life lies in inward focus (do not seek Yin-Yang externally). Quietly guard the Dantian (the "sovereign pass"), and with stable breath, health and longevity will follow naturally.

(Note: The "three vehicles" refer to the movement of essence, Qi, and spirit; "lead and mercury" symbolize the two energies of Yin and Yang; the Niwan Palace is the Baihui point at the crown of the head; "true water" and "true fire" correspond to kidney Yin and heart Yang, respectively.)

Interpretation of the Scripture on the Elucidation of Longevity:

Closing the eyes in quiet sitting nourishes the Shen (spirit), regulating the breath preserves Qi (vital energy), and firmly maintaining the lower Dantian (three inches below the navel) cultivates Jing (essence). When essence is abundant, Qi becomes vigorous; when Qi is vigorous, the spirit becomes complete—this is what Daoists call the "Three Treasures" of essence, Qi, and spirit.

In waking hours, harmonize with Yang Qi; in sleep, merge with Yin Qi. More waking hours strengthen the Hun (ethereal soul), while excessive sleep overpowers the Po (corporeal soul). Those with strong Hun thrive with vitality, while those with excessive Po tend toward decline. Therefore, those skilled in nurturing life must absorb the Qi of heaven and earth, reduce rich flavors in food, keep the spirit clear and the breath fresh, maintaining wakefulness day and night—this is the Dao of longevity.

Eliminate violent anger to cultivate the heart-mind, reduce excessive thought to nourish the spirit, speak sparingly to preserve Qi, and abandon cravings to foster essence.

The Miscellaneous Records of the Mysterious Pass recounts:

Once, a practitioner encountered three centenarians weeding in a field. Respectfully inquiring about their secret to longevity, the first elder said, "My wife is plain in appearance"; the second said, "I eat only half-full at dinner"; the third said, "I never cover my head while sleeping." Their words reveal the true essence of long life.

Practice the "Four Lessens": speak less, worry less, eat less, and sleep less. By following these four principles, one may attain the realm of immortals.

The True Explanation of Inner Cultivation states:

When Laozi speaks of "continuous, as if existing," the word "existing" refers to constant presence, while "as if" indicates it is not substantial existence. Thus, the Daoist teaching holds that the fundamental key is boundless emptiness, the practice method is knowing without grasping, and the cultivation work is the absence of scattered thoughts. All essential teachings of alchemical scriptures revolve around these principles.

In refining Qi, one must be soft rather than forceful, smooth rather than contrary, tranquil rather than chaotic, and gathered rather than scattered. Daoism most abhors anger, for once rage arises, Qi becomes rigid instead of soft, contrary instead of smooth, chaotic instead of tranquil, and scattered instead of gathered. A Daoist cultivator should be like a gentle breeze and bright moon, like auspicious clouds and fortunate stars—entirely free from violent energy—only then can true accomplishment in cultivation be achieved.

The Secret Records of Cultivating Truth explains:

If the human heart is indulged, it loses direction; if forcibly suppressed, it loses control. Indulgence harms one's nature, while suppression depletes the spirit. How then can the heart-mind be settled? In truth, the heart's nature is originally tranquil—it is stirred only by external things. Habitual agitation leads to restlessness, while habitual stillness brings ease and serenity. Thus, those skilled in cultivating stillness...

Interpretation of the Scripture of Longevity in Modern English:

When the mind becomes restless, calm it with stillness; when unwholesome thoughts arise, restrain them with right principles; when desires swell, temper them with detachment; when the mental state grows turbid, purify it with clarity. Maintain an easy and natural composure—without forced pursuit or laborious contrivance—preserving this state whether walking, standing, sitting, or lying down. Over time, external distractions will naturally fade, and the inner spirit (Shen) will grow lucid. True tranquility is attained not through deliberate effort but by letting it emerge spontaneously.

For those cultivating the Dao, the first step is to subdue the wandering mind. If one cannot conquer these restless thoughts, how can they perceive their true nature? Without seeing this nature, how can they establish the foundation of life? If both nature (Xing) and life (Ming) remain unfulfilled, how can genuine Dao be realized? Thus, with every reduction of desire, the heart of Dao grows stronger.

The heart governs the Yang Qi of the five organs, while the kidneys govern their Yin Jing (essence). When Yin Jing ascends, it transforms into fluids; when Yang Qi descends, it becomes vital fire (Yuan Qi). The navel, positioned at the body’s center, is called the "Central Palace of Life," storing essential Jing and connecting the Qi meridians. Skilled practitioners harmonize the heart (represented by the Li trigram) and kidneys (represented by the Kan trigram), uniting breath with mind so that Yin and Yang energies interact. This balance, known as "water and fire complementing each other," generates pure Yang Qi, leading to lightness and vitality.

In the womb, a fetus breathes through the mother, with mouth and nose closed, relying solely on the umbilical connection. At birth, when the cord is severed, the innate Yuan Qi gathers below the navel. Hence, the navel is the root of life and the pivot of primordial energy. By emptying the mind, focusing the spirit (Shen), and turning inward (a practice called "inner observation"), one may attune to the natural rhythm of breath at the Dantian—the "true breath of the perfected." Here, mind and breath unite, intention and Qi coalesce. Sustaining this state allows spirit and energy to return to their origin, merging nature (Xing) and life (Ming).

Humans dwell within Qi just as fish dwell in water. Water nurtures fish unnoticed; Qi sustains humans unbeknownst. To nourish Qi, begin by regulating breath: sit quietly, calm the mind as in meditation, gaze inwardly toward the nose, and focus intention on the navel until breath becomes even and gentle. Inhale—Qi rises from below; exhale—Qi descends from above. The rise and fall should be seamless, neither forced nor neglected, following nature’s flow with slight guidance.

The primordial spirit (Yuan Shen) often manifests through the eyes, where the essence of the five organs also gathers. Thus, the Yin Fu Jing states, "The pivot lies in the eyes," while the Daode Jing teaches, "Not seeing what excites desire keeps the mind undisturbed."

Interpretation of the Scripture of Longevity:

The method of inner cultivation requires keeping the eyes slightly closed ("dropping the curtains") and turning the gaze inward. Lower the fire of the heart (intention) into the Dantian (lower abdomen), allowing the spirit to remain deeply stored within the body, not scattering outward. This naturally enables the Shen (spirit) and Qi (vital energy) to merge, making the goal of longevity attainable.

"Minor Discourse on the Winter Solstice":

Within the human body lies a treasure hidden in the Dantian—light as mist, faint as drifting smoke. It ascends to the Muddy Pellet Palace (upper Dantian) at the crown of the head and descends to the Bubbling Spring at the soles of the feet, sometimes gathering and sometimes dispersing, taking on shapes both square and round. Inside and out, it glows with clarity, circulating endlessly within the body. When encountering Yin energy, it sinks; when meeting Yang energy, it rises. Like the Golden Elder (original spirit) gathering mercury (original essence) or the Crimson Maiden (original Qi) seizing lead (original essence), it follows the rhythm of the seasons, refining itself within the body.

From the Winter Solstice to the Summer Solstice, the Golden Cauldron (lower Dantian) boils like water, and the Jade Furnace (middle Dantian) burns like fire. The Azure Dragon of the East hums softly, while the White Tiger of the West roars. The Yellow Dame (spleen-earth) operates naturally, and the Elder Ding (heart-mind) remains in Wuwei (non-action). The Yin and Yang energies within the body intertwine like husband and wife, harmonizing like clouds and rain. The principle of "Heaven's first birth of water" (kidney water) lies in keeping its source pure, while the balance between the Li trigram (heart fire) and the Kan trigram (kidney water) must be guided by earth (spleen). Earth contains the nature of fire, and its mystery is transmitted through the heart.

In practice, one should be like a dragon nurturing a pearl submerged in a jade abyss, or a mother hen incubating an egg with steady warmth. Like a magnet naturally attracting iron or a flower's calyx protecting its fruit, preserve the original Qi effortlessly. Without forcibly holding on, one can still maintain it—as if always keeping one thing in mind. Cultivation begins with the Kan trigram (kidney water) and ultimately reaches the Qian trigram (pure Yang). During the Mao (5-7 AM) and You (5-7 PM) hours, bathe in stillness; in regulating the breath, balance exertion and relaxation. Once the Sacred Embryo (inner elixir) is formed, circulate it through the Three Passes (coccyx, spine, and jade pillow), driving the River Chariot (true Qi) in cycles. The Three Corpses (three destructive thoughts) and Six Thieves (six desires) will tremble in fear.

"Winter Solstice Verse":

Observing the Northern Dipper's celestial revolutions,

Suddenly, the divine secret is grasped.

A spark of true Yang is born in Kan (kidneys),

Filling the deficiency in Li (heart).

Creation works silently,

Yet fire arises from water (Yang from the kidneys),

The mystery lies in the Xuwei point (gate of life).

This year's Winter Solstice,

Plum blossoms still crystallize with frost as before.

Ancient sages secluded themselves on this day,

Setting an example for all beings.

All things contain life-force,

Especially at the transition between Zi (11 PM–1 AM) and Hai (9–11 PM).

Since time immemorial,

Heaven and Earth's Li and Kan (Yin-Yang) revolve ceaselessly,

Day and night without pause.

Now, having glimpsed the profound mechanism,

It is like the Golden Crow (sun) flying into the Moon Palace (Yin-Yang union).

"Song of the Mysterious Feminine":

The divine water (saliva) of the Hua Pool (mouth) is the root of Heaven and Earth—

Ingesting it in cultivation leads to longevity.

The secret never spoken by immortals of old

Is that the Mysterious Feminine (gate of Yin-Yang) is the true door to the Dao.

If asked what the Mysterious Feminine is—

The Scripture of Elucidating Longevity expounds the essential principles of Daoist cultivation:

Regarding Neidan (internal alchemy) practice:

Between the two kidneys, humans possess an innate spiritual radiance from the moment of conception. Cultivation requires tracing this primordial origin backward (reversion leads to elixir completion), rather than following the natural course of growth (progression makes an ordinary person). When the body's Yang Qi first stirs, one must seize this crucial moment - extracting essence from chaos (obtaining white from black) and nurturing vitality from emptiness (finding the One within nothingness). This process naturally generates "yellow sprouts" (the nascent form of the internal elixir), though sustained practice is required (three years or nine cycles of refinement). The true crucible (mysterious feminine) resides neither in the heart nor kidneys, but in tracing back to the primordial source where life first receives Qi.

On the essentials of authentic cultivation:

The core lies in "dual cultivation of nature and life." "Nature" refers to mental refinement - Lü Dongbin emphasized achieving a state of unclouded awareness through heart-mind purification. "Life" concerns Jing (essence) and Qi cultivation - masters like Zhang Boduan advocated regulating breath and nourishing Qi to strengthen foundational vitality. Only when the heart-mind detaches from external attachments can one truly cultivate nature; only when breath settles into the Dantian (primordial sea) can one truly establish life.

Three essential components of practice:

1. Jing: Maintain bodily purity and stillness - only by severing desires can essence be preserved

2. Qi: Maintain mental serenity and thoughtlessness - only thus can primordial Qi be conserved

3. Shen: Maintain focused awareness without dispersion - unifying body and mind in emptiness to fully realize spirit

Jing, Qi and Shen constitute the three essential materials (triple primal medicines) of cultivation, while body, heart-mind and intention form the three supreme keys (triple primal ultimates) of practice.
