《長生胎元神用經》

Scripture on the Divine Application of the Embryonic Spirit for Long Life

Chapter Ten

(Commentary by Layman Lang Zhao)

The master said: Those who truly comprehend the supreme Dao (the Way) will not have their lives taken by Heaven; those who absorb primordial Qi (vital energy) cannot be destroyed by Earth. The supreme Dao is not distant—it resides within one’s own body. With refined and diligent cultivation, life can be prolonged indefinitely.

The secret teachings of Master Liu (likely a revered Daoist adept) state: To attain longevity, one must cultivate the root of life. The method for cultivating this root begins with refining the subtle Qi into form—for the body is the fundamental vessel that holds Qi, and Qi is the origin of the body. By observing how primordial Qi animates the body, one can understand the principle behind its dissolution.

The scripture states: To deepen the roots and stabilize the foundation is the law of "long life and clear vision" (enduring vitality and spiritual insight). Primordial Qi is the root of the body; if one can stabilize it, the Dao of longevity is naturally grasped. How can the mother-child relationship (the interdependence of Shen [spirit] and Qi) within the body not be preserved? The Shen takes Qi as its mother, and Qi takes Shen as its child. The child (Shen) takes form through the breath, making the breath the mother. Only when the body and Qi are established can the Shen coalesce as the child.

The breath comes from the "Gate of the Mysterious Feminine" (referring to the mouth and nose): the nose inhales clear Qi, which is Yang, while the mouth exhales turbid Qi, which is Yin. In practice, one must achieve this: externally, no distracting thoughts arise; internally, the true Shen is maintained. The specific method is as follows: First, gently inhale clear Qi through the nose and slowly exhale turbid Qi through the mouth. Repeat this ten to twenty times, then close the mouth and allow the Shen and Qi to flow naturally in a continuous rhythm. Guide the inhaled Qi with the mind to the lower Dantian (three inches below the navel), visualizing a hazy "Mysterious Pearl" (the nascent form of the internal elixir) glowing faintly. Hold this pearl in contemplation as the ruler of the lower Dantian. Do not force it—persistent practice will naturally cause it to condense into a pearl. This is the "Mother Elixir." Once the Mother Elixir is formed, the Child Elixir will inevitably arise. The speed of progress depends entirely on one’s willpower. Do not seek outwardly; focus inwardly on nurturing the spirit, and the state of longevity will be swiftly attained.

When Shen and Qi merge, use the mind to guide their circulation through the organs, directing the breath to flow freely between the upper and lower body. With prolonged practice, consciousness will naturally become clear, and Qi will harmonize effortlessly. At advanced stages, inner vision (closed-eye visualization of the body) reveals the true Shen, and harmonious Qi will extend through the limbs, moving at will—even capable of healing others’ ailments.

The Yellow Emperor, through the method of inner vision, cultivated for three months and gave birth to the "Heart Spirit," which could generate energy to nourish the five organs. This principle can be verified through practice—the Yellow Emperor attained this secret and achieved realization through three months of inner vision cultivation.

This scripture elucidates the core principles of cultivating longevity through the Dao: the relationship between Shen (spirit-consciousness) and Qi (vital energy).

The key to Dao cultivation lies in harmonizing Shen and Qi. The Daoist master Liezi achieved realization after nine years of practice—the speed depends on one's willpower. When the mind becomes tranquil, the primordial Qi (innate energy) flows naturally, and physical health follows spontaneously. The Mysterious Pearl (referring to the Dantian) serves as the sovereign; when Shen resides within it, radiance emerges.

Ordinary people today experience separation between Shen and Qi—like mother and child parting ways. Though breathing continues, the spirit remains tethered to external distractions. Consequently, Qi loses its governance and stagnates, causing essential Jing (essence) to dissipate. Imagine Shen as the master and the body as a house: when the master never returns to tend it, the dwelling inevitably decays. A person breathes 13,500 times daily, with Qi circulating through 81,000 inches of pathways, yet the spirit expends itself externally without a moment's internal presence. Seeking longevity under such conditions proves exceedingly difficult.

The secret of cultivation lies in letting Shen govern Qi's movement. Merely allowing natural respiration only aids digestion—it cannot achieve "reverting Yin to Yang" (balancing Yin-Yang) or replenishing marrow and essence. True practice requires primordial Qi to condense into an "embryo" (Neidan, internal elixir), within which Shen resides. Only when Shen becomes whole can it fully command primordial Qi.

The method: envision Shen as a chariot and Qi as the horses—driving them ceaselessly yet without exhaustion. Continuously focus on uniting Shen with primordial Qi, directing them at will. Let Shen within the Mysterious Pearl (Dantian) govern respiration, observing the true spirit internally with each breath. When Shen and Qi merge, breathing never becomes disordered. The Qi regulation pathway runs from the Muddy Pellet Palace (upper Dantian) at the crown to the Gate of Life (lower Dantian) three inches below the navel. The Yellow Court Scripture (Huangting Jing) mentions a "secret portal" (Gate of Life) at the lumbar region and a "gate of birth" (Dantian) in the abdomen—these are crucial sites for cultivation. Such immortal secrets weren't meant for casual disclosure; they're revealed only through spiritual resonance.

(Note: "Muddy Pellet" refers to a key acupoint in the brain, while "Gate of Life" denotes an important Daoist cultivation point three inches below the navel. The Yellow Court Scripture is a renowned Daoist classic.)

This scripture elucidates the Daoist practice of cultivating the "fetal origin" (a metaphorical term for the inner elixir in Neidan/internal alchemy), focusing on nourishing the spirit (Shen) and gathering Qi (primordial energy) through breath regulation. The core principles are as follows:

The key to cultivation lies in connecting the "Two Scenes" (referring to the Muddy Pellet Palace in the upper Dantian and the lower Dantian): When the primordial Qi in the lower Dantian becomes abundant, one must guide it to reverse its flow upward to the crown's Muddy Pellet Palace—this is called "returning essence to replenish the brain." If the mind fails to govern the breath during respiration, the Qi will remain incomplete. Only when spirit and Qi remain united in every breath can one achieve what is termed "complete harmony of Shen and Qi."

Practical methods:

1. While exhaling, visualize Qi being inhaled through the nose, descending all the way to the lower Dantian (the Mysterious Pearl), where it merges with the primordial spirit.

2. Purify the mind, close the eyes to observe the breathing process internally, and maintain contemplation of the true spirit—only then can the breath become complete.

3. If the eyes wander outward, causing the mind to scatter, the inner Qi will lose its governance—this is called "incomplete breath."

The mystery of "fetal formation":

• The fetal origin is condensed through Qi absorption (breath regulation and Qi nourishment), while respiration itself relies on the fetal origin for sustenance.
• Inhale through the nose and guide the Qi with intention to the lower Dantian. With prolonged practice, a "fetal form" will naturally coalesce within the body.
• This "fetus" resembles the initial conception of a human being, directed by the primordial spirit and gradually taking shape.

Signs of successful cultivation:

Men will gather primordial Qi (accumulating essence at the Guanyuan acupoint), while women will experience abundant fetal vitality. At this stage, even if desires arise, they will not disturb the primordial spirit—this is the Shangqing (Upper Clarity) realm of "transforming essence into spirit," an advanced state of practice.

Practical口诀 (oral instructions):

1. The optimal time is between midnight and the fifth watch (1-5 AM), just upon waking.

2. First, stir the lips and teeth with the tongue, then expel turbid saliva in three portions. Inhale cool, fresh Qi through the nose to the chest and diaphragm.

3. Exhale stale overnight Qi in three gentle "ha" breaths. Shortly after, swallow the clear Qi and lie supine while stretching the limbs.

4. Knock the teeth nine times, maintain natural breathing (avoid forced depth or length), and when the breath stabilizes, hold it briefly before swallowing the primordial Qi.

5. Use the hands to guide Qi downward to the Sea of Qi (lower Dantian). After twenty days, when Qi flows smoothly, increase to two swallows; after two months, add another swallow.

Note: The entire process must progress gradually. Hand guidance is necessary in early stages but can be discontinued later.

This scripture details Daoist practices for cultivating the "Fetal Origin" (primordial Qi), divided into three main methods: Qi absorption, visualization, and healing techniques.

I. Qi Absorption Method

1. Timing: Practice on an empty stomach between midnight (11 PM-1 AM) and noon (11 AM-1 PM), as these yang hours are optimal. Avoid yin hours before midnight and after noon.

2. Technique:

• Beginners: Swallow breath three times per session, increasing to four after one year
• Perform 5-10 swallowing cycles per session
• Avoid inhaling turbid external Qi

II. Grain Abstinence Visualization (Bigu)

1. At meal times, rinse mouth and sit quietly. Visualize two white Qi streams from the "Upper Origin" (Upper Dantian):

• Thick as cloth ropes, flowing from the brain
• Descending along the spine to the "Qi Sea" (Lower Dantian)
• Condensing into an egg-sized luminous sphere emitting fragrance to suppress hunger

2. Precautions:

• Maintain focused awareness without distraction
• If experiencing dry mouth or throat obstruction (indicating upper burner heat):
• At dawn, inhale cool Qi through nostrils to cleanse the chest
• Exhale with "he" sound 30-50 times (100-200 for severe cases)
• Stop when sweetness appears in the mouth
• For excess cold Qi:
• At sunrise, inhale yang Qi through nose
• Exhale cold Qi through mouth about 100 times

III. Healing Methods

1. General therapy: Sit quietly holding breath, direct internal Qi to affected area 200 times

• Effective for: Various pains, venomous bites, animal scratches

2. Specific treatments:

• Cold feet in winter: Swallow warm Qi, guide it mentally to soles
• Preventing drunkenness: Exhale slowly while drinking to expel alcohol toxins

3. Key concepts:

• "Red Water" signifies blood, "Mysterious Pearl" denotes primordial Qi
• Primordial Qi constitutes the essence of Shen (spirit)

IV. Internal Vision & Spirit Retention

Practice facing east or south with closed eyes, visualizing:

1. Location: Lower Dantian (three inches below navel between kidneys)

2. Imagery: A three-inch cubic space containing five-colored Qi:

• Left green, right yellow, upper white, lower black, center red

3. Three Inner Deities:

• Upper: Yuanxian (styled Emperor's Minister) in red robe/shoes, seated on golden throne holding golden censer
• Middle: Zidan (styled Radiant Fortitude)
• Lower: Yuanyang (styled Valley Origin)
• These deities reside in Upper Dantian by day, returning to Lower Dantian at night

Essential technique: Visualize a tangerine-colored luminous sphere (size of a pellet) in the Dantian, containing flame-like radiance where three three-inch-tall red-robed deities dwell.

This scripture primarily discusses two aspects: the fundamental principles of Neidan (internal alchemy) cultivation and specific Daoyin health-preserving exercises.

[Principles of Neidan Cultivation]

The essence of cultivation lies in nurturing the Shen (spirit, specifically the primordial spirit). To achieve this, one must progressively cultivate the following elements:

1. First, nourish Qi (primordial vital energy)

2. To nourish Qi, one must first nourish the brain (the Mudan Palace, or upper Dantian)

3. To nourish the brain, one must first cultivate Jing (essence)

4. To cultivate Jing, one must first nourish the blood

5. To nourish the blood, one must first cultivate saliva

6. To cultivate saliva, one must first nourish the "water" (referring to the golden fluid and jade liquid beneath the tongue)

The transformation process unfolds as follows:

• The "water pool" between the teeth beneath the tongue secretes fluids, which are swallowed and enter the lung meridian to transform into saliva
• Saliva enters the heart region and transforms into blood
• After circulating for 250 days, blood enters the kidney meridian and transforms into Jing (essence)
• Jing ascends through the brain meridian and transforms into energy in the Mudan Palace
• Two channels from the Mudan Palace flow along the spine into the Qi Sea (lower Dantian)
• When the Qi Sea becomes full, one gains acute hearing and clear vision

[Cultivation Taboos]

The text particularly emphasizes that practitioners must avoid anger and refrain from carelessly dissipating vital energy. Discretion in speech and action is essential.

[Daoyin Exercises]

1. Facial massage: Rub hands warm and massage the face like washing to prevent wrinkles

2. Bow-pulling posture: Mimic drawing a heavy bow like a warrior, three times each side

3. Fist thrust: Alternate punching forward with left and right fists multiple times

4. Weight-lifting posture: Alternate lifting motions as if holding heavy stones

5. Mountain-pushing posture: Sitting with fists, twist torso sideways as if pushing mountains

6. Neck rotation: Hold head and rotate neck to mobilize cervical vertebrae

7. Spinal movement: Bend forward with hands on ground, arch and relax spine three times

8. Back percussion: Sitting position, strike back with reversed hands three times

9. Leg stretch: Sitting with legs extended, pull feet with hands

10. Waist twist: Standing with hands on hips, lean backward three times

11. Foot massage: Rub palms warm and massage soles and knees

12. Neck resistance: Cross hands behind neck and apply counter-pressure

13. Ear massage: Rub hands warm and massage ears thirty times

14. Nasal clearing: Hold breath and press sides of nose until airways open

[Essential Techniques]

Recommended practice between Zi hour (11pm-1am) and Wu hour (11am-1pm):

1. Swallow saliva seven times

2. Close eyes and sit quietly, visualizing internal organs

3. Beginners should gradually achieve hearing no sounds and having no distracting thoughts

4. Start with three to five breath cycles, gradually extending to twelve cycles

(Note: "Breath cycle" refers to one complete inhalation and exhalation)

This scripture expounds the Neidan (internal alchemy) practice of "visualizing the sun and moon" in Daoist cultivation, describing how to refine Jing (essence), Qi (vital energy), and Shen (spirit) through solar and lunar contemplation.

At the initial stage of practice, if one's Qi circulation remains obstructed, only minor spiritual powers can be attained. When the Qi flows smoothly, greater spiritual capacities emerge. The method involves maintaining dietary moderation and ritual purity while visualizing the sun and moon within the mouth—the sun during daytime, the moon at night. The sun should be imagined as a crimson disk with purple radiance emitting nine rays of light, while the moon appears as a golden-white halo with ten luminous beams.

Next, transfer these celestial images to the Mingtang (the upper Dantian between the eyebrows): the sun positioned left, the moon right. Continuously swallow their radiant energies as naturally as breathing during sleep. Alternative visualizations place the sun at the forehead and the moon below the navel. For physical discomfort, press the tongue against the palate while repeatedly swallowing saliva to restore balance.

The "Qi" mentioned here refers to the vital energy of the twenty-four corporeal deities within the human body. Shen (spirit) and Qi mutually transform—where Shen resides, Qi gathers; where Shen departs, Qi scatters. Dispersed Qi becomes mist, while condensed Qi takes form. This energy ascends to crystallize as the Three Origins (the upper, middle, and lower Dantian) and descends to generate all phenomena.

During practice, close the eyes and visualize: all divine spirits dissolve into white Qi resembling rising mist from the Mysterious Pearl (Dantian) and reproductive organs, entering through the mouth. Feel this white Qi circulating from the soles, heart of the feet, and crown through the entire body, merging with one's being. The white Qi then transforms into purple clouds entering through the mouth, filling the five viscera, circulating through the extremities, and finally unifying with the body's purple aura.

Advanced visualization involves: the purple Qi permeating the entire chamber before being stirred by breath from the mouth, swirling into a three-inch-tall figure called the "Great Cavern Emperor-Oneness Sovereign." Imagine this sovereign entering through the mouth and ascending to sit solemnly in the Hexagonal Palace of the Purple Chamber (heart region). His left hand holds the practitioner's five immortal registers, while his right grasps five talismanic charms. Nine solar rays glow at his left mouth corner and lunar radiance at the right—these luminous Qi currents flow through internal organs and joints, illuminating the body like daylight.

The practice concludes with silent incantation: "Great Cavern Emperor, Supreme Simplicity Sovereign Spirit, father serene and mother tranquil, dual harmony perfected, hundred..." (incomplete mantra). This cultivation centers on unifying form and spirit through the fusion of solar-lunar energies with the body's divine Qi.

This passage explains the Daoist cultivation methods of "embryonic respiration" (taixi) and "ingesting Qi" (fuqi). Here's a modern interpretation:

During practice, one must first visualize: imagine the "Great Cavern Emperor Unity Venerable Lord" (Dadong Diyi Zunjun) seated at the philtrum (the midpoint between nose and upper lip). This divine being holds the sun and moon in its mouth, their radiance illuminating all the body's meridians. Before beginning breathing exercises, visualize a candle flame igniting in the heart, allowing its fire to spread throughout the body to purge the turbid energies from consumed grains. However, this visualization should be moderate—prolonged focus may cause agitation.

Key practice methods:

1. Breathing should be gentle, continuous and elongated, allowing primordial Qi (Yuanqi) to naturally circulate through the body. Guide the Qi flow with focused intention.

2. To practice Qi ingestion, one must first gradually reduce food intake, avoiding haste. After persisting for a year, when the body's genuine Qi becomes abundant, hunger will naturally cease.

3. The kidneys house six divine officials (Minister over the Masses, Recorder, Director of Destinies, Colonel Director of Retainers, etc.). The left kidney is called "Mysterious Marvel Lord" (Xuanmiao Jun) and the right "Mysterious Origin Lord" (Xuanyuan Jun)—these are the fundamental roots of the human body.

The text particularly emphasizes: the physical form relies on Qi, while Qi depends on the form—the two complement each other. Practitioners must simultaneously refine both body and Qi to achieve longevity. The author recounts spending over a decade seeking authentic methods, until during the Dali era (766-779 CE) of the Tang dynasty when he met Master Wang returning from Mount Heng (the Northern Sacred Peak) to Mount Luofu, finally receiving true transmission.

Essential cultivation techniques include:

• Five Sprouts Method (visualizing the five viscera corresponding to directional Qi)
• Six Healing Sounds (using six specific sounds to regulate organs)
• Qi Ingestion (absorbing celestial and earthly essences)
• Embryonic Respiration (imitating fetal breathing patterns)

Special caution: The Qi absorption method is too intense for ordinary practitioners. The true path involves cultivating embryonic respiration through Qi circulation (guiding the movement of vital energy).

Plain Language Interpretation of The Scripture of Embryonic Breathing and Divine Function:

The physical body serves as the foundation for spiritual cultivation. Those wishing to practice Qi absorption (Daoist breath regulation techniques) must first select a refined and tranquil chamber, maintaining constant incense burning nearby. The meditation platform should have thick, soft padding elevated two to three feet above the ground, with a one-inch pillow. During the midnight Zi hour (optimal time for Yang energy activation) or at dawn upon waking, begin by exhaling turbid Qi from the abdomen nine times. If practicing at other times, choose moments when the weather is mild and the stomach empty.

The method: Close your eyes and knock the teeth thirty-six times to awaken the internal Shen (spirit). Press the eye corners with fingers, rotate to massage the nasal wings and earlobes, rub the face, and move all joints. Then press the tongue against the upper palate, swallowing the accumulated saliva in three portions to nourish the five viscera and bring radiance to the complexion. At this point, relax the mind, visualizing yourself as boundless as empty space, releasing all burdens.

For beginners: During practice, keep the mouth closed and maintain the "firm grasp" posture (thumb pressing the base of the ring finger). Seal the Jing (essence) passages to prevent leakage. In initial stages when Qi circulation isn't smooth, don't force this posture—wait until after a hundred days or half a year when you feel Shen-Qi flowing freely and the body perspires naturally before adopting it fully.

The turbid Qi purification method: Each of the five viscera has its guardian Shen. When lying still at night while holding the breath, first rotate the abdomen to expel stagnant food residues and turbid Qi before regulating respiration. Assume a supine position with closed eyes in firm grasp posture, placing both fists beside the breasts while raising the knees and lifting the pelvis. Contain the breath to activate Dantian (energy center) Qi's internal-external circulation, completing the adjustment with nine exhalations.

Key points of breath regulation: The essence lies in swallowing. Ordinary people often confuse internal and external Qi—true breath regulation emphasizes continuous natural flow. The human body inherently possesses primordial Qi (Yuanqi). With each swallow, internal and external Qi resonate, allowing Dantian energy to circulate spontaneously. When swallowing, keep the mouth closed and make quick gulping motions, producing gurgling sounds as the Qi descends leftward through twenty spinal segments like dripping water. Repeat on the right side to clarify the internal Qi. Mental intention may guide the process, supplemented by hand movements.

(Note: Technical terms like "Qi absorption," "firm grasp," "primordial Qi," and "Dantian" are preserved with parenthetical explanations. Traditional temporal references and postures are adapted into contemporary language while maintaining the original text's instructional essence within 1.5 times its length.)

This passage explains the Daoist practice of "Ingesting Qi" (Fuqi), a vital energy cultivation method:

The method focuses on the Qi Sea (lower Dantian, located three finger-widths below the navel). Beginners experiencing blockages in the upper burner (chest region) may use hand massage to facilitate Qi's downward flow. When swallowing Qi feels obstructed, apply slight force to create an audible swallowing sound. Once Qi flows smoothly, massage becomes unnecessary.

The technique involves: Close the mouth and swallow Qi three times consecutively, followed by two dry swallows—this is called "Cloud Moving." Then mix the saliva in your mouth and swallow—this is "Rain Nourishing." Novices may pause after one or two swallows, gradually building to three continuous swallows. Consistent practice yields minor results within a year, with significant attainment requiring two to three years.

Key principles: Behind the lower Dantian lie two acupoints connecting the spinal meridians, which ascend to the Muddy Pellet Palace (Niwan Gong, the upper Dantian in the brain). After each three-swallow cycle, guide primordial Qi through these points. Visualize twin white Qi streams rising along the spine to the brain, then descending sequentially: first nourishing hair, face, neck, arms and fingers; then entering the chest, abdominal organs and skin; passing through the middle Dantian (heart center); returning to the lower Dantian; and finally flowing down the tailbone, knees, ankles to the Bubbling Spring points (Yongquan, on the soles).

This mirrors cosmic rhythms: like thunder energizing primordial Qi and rain nourishing creation, the body requires swallowed fluids to nurture organs and refined essence to replenish the brain. Without regulated breathing, internal Qi cannot circulate—this embodies the Dao of harmonizing with heaven and earth.

During practice, visualize turbid Qi and stagnant blood being cleansed by vital energy, expelled through fingertips and toes. Keep fingers extended, not clenched. One complete cycle is called "one circulation" (Yi Tong), which dispels illness. After stabilizing breath, repeat the swallowing process. Thirty-six swallows constitute basic mastery. Those not yet achieving grain abstinence (Bigu) should maintain light, moderate diets.

(Note: "Ingesting Qi" is a core Daoist practice absorbing celestial-earthly essence through specialized breathing. The "Muddy Pellet Palace" refers to the upper Dantian behind the brow; "Bubbling Spring" is a key acupoint on the sole.)

Interpretation of the Scripture on the Embryonic Spirit of Longevity and Its Divine Functions:

On Dietary Regulation and Breath Control:

Practitioners should maintain an empty stomach during exercises. Whether sitting or reclining, one may swallow Qi when the abdomen is empty. Perform ten sets per session, totaling 360 Qi-swallowing repetitions. With prolonged practice when the breath flows smoothly, all 360 repetitions may be completed in one session. Intermediate achievement requires 1,200 breath cycles, while greater mastery demands more. Neglecting physical cultivation and constitutional transformation renders one like withered wood—devoid of Jing (essence), Qi (vital energy), and Shen (spirit).

Qi Refinement Method:

In leisure time, seek a quiet chamber. Remove outer garments, loosen hair, and recline supine with hands relaxed—not clenched—while spreading hair across the mat. Regulate breathing to begin Qi-swallowing. Upon completion, maintain a thought-free mind, allowing Qi to circulate naturally. Should chest tightness occur, exhale; adjust when breath becomes rapid. As Qi flows smoothly, gradually increase repetitions to 20-30, then 40-50 until perspiration appears—this signals efficacy. Remain calmly reclined without immediately rising into drafts. Drowsiness or physical discomfort warrants discontinuation. Practice fortnightly.

Illness-Treating Breath Retention:

For ailments caused by improper cultivation, immediately enter a secluded room. Extend limbs per breath-regulation methods, focusing intent on affected areas during Qi-swallowing. Retain breath to "attack" pathogens until exhalation, then repeat. Conduct 20-50 such attacks until the afflicted area becomes moist with sweat. For persistent conditions, repeat this intent-focused attack from midnight until dawn until recovery. This method proves effective against diverse maladies.

Qi Emission Therapy:

When treating others with one's primordial Qi, first identify which of the patient's Five Organs is affected. Project your Qi into their body, having them face specific directions while calmly regulating breath. This emission method resembles Qi-swallowing, capable of eliminating all disorders and permanently dispelling pathogenic influences.

Essential Breath Regulation Principles:

Humans consume the Five Grains, whose Five Flavors enter corresponding organs while turbid Qi accumulates in the mouth. The Six Bowels and Triple Burner's foul energies likewise form turbid Qi. Upon waking...

This scripture primarily discusses dietary prohibitions and regulatory methods for practicing Neidan (internal alchemy, focusing on refining the embryonic spirit). It is divided into two sections:

[Diagnosing Physical Signs]

When symptoms such as dry mouth, flushed and shiny cheeks, and loss of appetite appear, these indicate excessive heat in the upper jiao (the heart and lung region). In such cases, one should open the mouth wide and take ten to twenty deep breaths, then perform "Drumming the Heavenly Drum" (lightly tapping the back of the head with fingers) seven to nine times, followed by swallowing the saliva in the mouth. If a clear, sweet saliva is produced, it signifies the dissipation of internal heat and the cooling of the five viscera. If the saliva remains bland and tasteless, with no appetite for any food—even plain grains and water becoming difficult to swallow—this indicates a cold condition in the body, requiring regulation through the "Chui" (blowing) breathing technique.

[Dietary Guidelines]

1. Fundamental Principles: Those practicing Qi absorption (breath regulation and energy refinement) must strictly adhere to dietary restrictions. Only consume beneficial foods; absolutely avoid harmful ones, as indiscriminate eating disrupts the body's righteous Qi. Daily meal arrangement:

• Morning: A small portion of plain porridge or sesame porridge (to nourish spleen Jing and generate fluids).
• Noon: A small portion of light wheat-based foods (such as noodles or flatbread), avoiding overly hot items.
• Recommended foods: Onion and garlic soup, soft-boiled sweet and mild dishes, and barley (suitable year-round but not in excess).

2. Absolute Prohibitions:

• During purification rituals and quiet cultivation, abstain from the "Thirty-Six Fowl" (animals considered impure in Daoism) and those corresponding to one's zodiac animal.
• Minimize consumption of jujubes, chestnuts, taro, malt, and foxnuts (as these can provoke pathogenic Qi).
• It is better to be slightly hungry than overeat (as fullness obstructs the flow of Qi in the five viscera).
• Avoid scalding foods, overly salty or sour flavors, spicy dishes, and spoiled food.

3. Dietary Techniques:

• Before meals, swallow three to five breaths of Qi, then eat two or three raw black beans (to help unblock the three jiao and harmonize the organs).
• After eating, use the "He" (exhaling) technique to expel turbid Qi from the abdomen.
• If accidentally consuming toxic food, address it immediately.

4. Special Circumstances:

• After Qi absorption practice, if turbid Qi (impure energy) needs to be expelled, do not suppress it.
• A moderate amount of alcohol on an empty stomach daily (warmed in winter, cooled in summer) can aid Qi circulation.

(Note: The methods mentioned—"Drumming the Heavenly Drum," "He technique," and "Chui technique"—are all breathing and exhalation practices from Daoist health cultivation.)

This scripture discusses the essential principles for maintaining vital Qi (life energy) during Neidan (internal alchemy) practice in Daoist cultivation:

On alcohol consumption:

Pathogenic Qi (negative energy) particularly fears excess. Overdrinking clouds consciousness, while drunkenness damages Shen (spirit), depletes primordial Qi, and shortens lifespan. If drinking is unavoidable, immediately perform the "He" exhalation technique (a breathing method) 30-50 times after consumption. Opening the mouth wide while drinking and exhaling helps expel alcohol toxins, making intoxication less likely. However, complete avoidance of drunkenness is ideal, as is abstaining from slaughterhouse-derived foods to evade death-related foul Qi.

Daily precautions:

Quickly avoid encountering running livestock or foul odors, as these harm vital Qi. If accidentally inhaling impure Qi, use breath regulation techniques to cleanse and expel it. After drinking, consume 2-3 cups of water or use vital Qi to naturally flush out alcohol residues—never force expulsion, but let it discharge naturally.

Key cultivation points:

Minimize greasy foods to prevent interference with vital Qi. Correct any violations of taboos promptly. Consistent Qi absorption practice (breathing cultivation) for one year equals three years of progress. When primordial Qi becomes concentrated, such disturbances cease to matter. Practicing a thousand breath cycles daily isn't excessive.

Advanced cultivation stages:

The scripture states: First year transforms Qi, second year transforms blood, third year transforms meridians, fourth year transforms muscles, fifth year transforms bone marrow, sixth year transforms tendons, seventh year transforms bones, eighth year transforms body hair, and ninth year achieves complete physical metamorphosis. When all 36,000 body deities (Daoism posits spiritual presences throughout the human form) become immortalized, one becomes a Zhenren (Perfected Being). Unrelenting practice strengthens joints, stabilizes the five viscera, grants immunity to temperature extremes, and ultimately achieves longevity matching the sun and moon.

Grain avoidance methods:

After three years of proper cultivation when vital Qi circulates freely and Jing (essence) becomes substantial, natural disinterest in grains arises. When hungry, practice saliva swallowing and Qi absorption without strict schedules. Herbal supplements may assist, but constant reliance on medicines isn't superior practice.

Quoting the Huangting Jing (Yellow Court Scripture): "Though the Five Grains contain earth's essence, their flavors attract pathogenic Qi and disturb spiritual clarity. Better to directly ingest the Great Harmony Qi of heaven and earth—this truly reverses aging and achieves deathless immortality."

(Note: "Three Corpses" refer to three internal troublemaking spirits in Daoist physiology, while "Triple Burner" denotes a bodily division in Chinese medicine.)

This passage from the Scripture of the Divine Embryo and Celestial Functions for Longevity reveals essential principles for cultivating life and practicing the Dao. Here's how we might understand it:

Most people today, as in ancient times, remain trapped in worldly desires. Yet sacred texts remind us that many only value their bodies when facing death, seek repentance after wrongdoing, or look for medicine when already ill—like trying to escape after Heaven's net has closed, when regret comes too late.

Truly wise practitioners awaken before crises strike. The key to Dao cultivation lies in Qi (primordial vital energy), the sovereign of the body and root of life. Only by treasuring Jing (essence) and nourishing Qi can one preserve life.

Key insights:

1. Cultivating the Dao means nurturing Qi—preserving Qi leads to attaining the Dao and longevity. Shen (spirit) manifests through Jing-Qi: abundant essence brings mental clarity, while exhausted essence scatters consciousness. Jing forms the foundation for blood circulation and bone strength; its depletion brings death.

2. Practice requires focused Jing-Qi preservation. The methods transmitted by Pengzu (ancient longevity immortal) teach: guard essence without leakage to become impervious to cold/heat and attain natural mental tranquility.

3. The path is surprisingly simple: avoid sensory indulgence, disregard fame/shame, and prevent physical exhaustion. Regular daoyin (ancient qigong) practice with breath regulation extends lifespan. The supreme method? Maintain unbroken essence conservation. Reducing desires and releasing distractions naturally prolongs life.

4. Practical techniques:

• Upon waking, tap teeth 7-9 times
• Kneel facing east, balancing breath
• Inhale pure Qi through nose, exhale turbidity through mouth
• Massage the body systematically
• Press tongue to palate, swallow accumulated saliva in three portions
• Massage from crown to soles seven times

This routine unblocks sinews, regulates Qi-blood, expels pathogenic turbidity, and replenishes deficiencies.

5. The text also mentions "Three Corpses and Nine Worms" (Daoist concept of parasitic organisms harming health):

• Fu worms (0.4 inches, chief parasites)
• Roundworms (1 foot, fatal if reaching heart)
• Tapeworms (1 inch initially, growing to 4-5 feet)
• Flesh worms (rotten apricot-like)
• Lung worms (silkworm-like)
• Stomach worms (toad-like)
• Diaphragm worms (melon-seed-like)
• Red worms (raw meat-like)
• Pinworms (vegetable worm-like)

These parasites must be eliminated to maintain health.

This scripture describes nine types of parasites residing in the human body that cause various illnesses, along with corresponding herbal formulas and administration methods.

The nine internal parasites are:

1. Lung Parasite: Causes chest tightness and coughing

2. Stomach Parasite: Leads to nausea and vomiting
