《修真十書鍾呂傳道集》Vol. 3

This dialogue between Zhongli Quan and Lü Dongbin discusses the key concepts of Neidan (internal alchemy) cultivation. Zhongli Quan explains that spiritual practice progresses through three stages: first refining the physical form into Qi (vital energy), then refining Qi into Shen (spirit), and finally merging Shen with the Dao to achieve transcendence. This complete process is metaphorically called the "Purple River Chariot," representing the full celestial cycle of energy circulation.

Regarding the "Returned Elixir" (the core concept of Neidan practice), Zhongli clarifies that the elixir isn't defined by color or taste, but refers to the three Dantian (energy centers) in the human body: the upper Dantian (Shen's abode in the head), middle Dantian (Qi's residence in the chest), and lower Dantian (Jing's region in the abdomen). Jing, Qi and Shen correspond respectively to these three centers: Jing generates Qi in the lower Dantian, Qi generates Shen in the middle Dantian, and Shen resides in the upper Dantian. However, without continuous circulation of Jing and Qi, these energy centers remain inactive.

Lü Dongbin inquires how to permanently anchor these three vital forces in their respective palaces. Zhongli elaborates: The Qi generated from the kidneys contains the "Water of True Unity" (primordial energy), which must return to the lower Dantian to nourish the spiritual root. The fluid generated from the heart contains the "Qi of True Yang" (pure yang energy), which must return to the middle Dantian to nurture the spiritual source. By gathering spiritual energy to form Shen, then unifying Shen with the Dao in the upper Dantian, one attains liberation.

Finally, when Lü asks about the profound principle behind the "Returned Elixir," Zhongli explains it as a process of "going forth and returning to the origin" - the cyclical return of Jing and Qi to their source. This dialogue systematically presents the essential teachings of energy transformation and Dantian application in Neidan practice.

Zhongli Quan (one of the Eight Immortals in Daoism) explains that within alchemical practice, there exist elixirs of varying grades: Minor Reverted Elixir (Xiao Huandan), Major Reverted Elixir (Da Huandan), Sevenfold Returned Elixir (Qifan Huandan), Ninefold Transmuted Elixir (Jiuzhuan Huandan), Golden Fluid Elixir (Jinye Huandan), and Jade Fluid Elixir (Yuye Huandan). These elixirs differ not only in name but also in their specific cultivation timings and methods.

The Minor Reverted Elixir begins its cultivation from the lower Dantian (located three inches below the navel). The lower Dantian serves as the foundation of the five viscera and the basis of the three Dantians (upper, middle, and lower). Its practice follows the generative cycle of the Five Phases (Water generates Wood, Wood generates Fire, Fire generates Earth, Earth generates Metal, Metal generates Water), guiding the nascent Qi during these generative moments. Simultaneously, it observes the restraining cycle (Fire restrains Metal, Metal restrains Wood, Wood restrains Earth, Earth restrains Water, Water restrains Fire), supplementing the restrained Qi during these phases. Like the mutual affection between mother and child or the harmonious union of husband and wife, it facilitates the cyclical movement of Qi and fluids. The period from Zi hour (11 PM-1 AM) to Wu hour (11 AM-1 PM) represents the time of Yin-Yang generation, while Mao hour (5-7 AM) to You hour (5-7 PM) marks the balance of Yin-Yang. Completing one full diurnal cycle of this circulation through the lower Dantian constitutes the Minor Reverted Elixir. Practitioners employ this method to "gather the medicinal ingredients" (collecting bodily Jing and Qi) and "apply the fire" (directing with intention), ultimately refining the lower elixir.

The Major Reverted Elixir represents a more advanced practice requiring the "dragon-tiger congress" (union of original Shen and original Jing) to produce "yellow sprouts" (initial signs of golden elixir formation). Through "extracting lead and adding mercury" (regulating Yin-Yang), the great medicine is refined. When vital energy rises from the Black Tortoise Palace (kidneys) and true Qi ascends from Mount Jade Capital (crown of the head), the "river chariot" circulation is activated (Qi ascending along the Governing Vessel and descending via the Conception Vessel), irrigating the central channel with "jade fluid" (saliva). As vital energy circulates from lower Dantian to upper Dantian (between eyebrows) and returns downward, completing the grand celestial cycle, the Major Reverted Elixir is achieved. Through this method, practitioners nurture the "embryonic immortal" (internal elixir), generate true Qi, and ultimately refine the middle elixir.

As for the Sevenfold Returned Elixir and Ninefold Transmuted Elixir, these involve deeper alchemical principles. Zhongli Quan references the generative number of the Five Phases totaling fifty-five (1+2+3+4+5+6+7+8+9+10=55), along with the numerical correspondences of celestial Yang and earthly Yin (Heaven 1-Earth 2, Heaven 3-Earth 4, etc.), all representing cosmic laws that must be observed during elixir refinement.

The passage explains the operational principles of Yin-Yang and the Five Phases (Wood, Fire, Earth, Metal, Water) within the human body, along with methods for cultivating Neidan (internal alchemy).

The five internal organs correspond to the Five Phases: kidneys govern Water, heart governs Fire, liver governs Wood, lungs govern Metal, and spleen governs Earth. Each organ possesses dual Yin-Yang attributes represented numerically: kidneys correspond to 1 (Yang) and 6 (Yin), heart to 2 (Yang) and 7 (Yin), liver to 3 (Yang) and 8 (Yin), lungs to 4 (Yang) and 9 (Yin), and spleen to 5 (Yang) and 10 (Yin). These numbers signify the generative and transformative patterns of the Five Phases.

During the circulation of Yin-Yang Qi within the body: when Qi flows to the liver, the kidney's Yin energy becomes exhausted; when Qi moves to the heart, new Yin energy is generated. Similarly, when bodily fluids reach the lungs, the heart's Yang energy depletes; when fluids circulate to the kidneys, fresh Yang energy emerges. This cyclical process illustrates the fundamental Daoist principle of Yin-Yang waxing and waning.

Neidan practitioners must first employ the method of "mating the dragon and tiger" (harmonizing heart and kidney Qi) to extract pure Yang energy from the heart (represented by the heart's number 7). This Yang energy first returns to the middle Dantian (located at the solar plexus), then descends to the lower Dantian (below the navel) to nurture the "embryonic immortal" (the nascent form of internal elixir), before finally cycling back to the heart—a process known as "sevenfold reversion to form the elixir."

At advanced stages of practice, when both the liver's Yin energy (8) and heart's Yin energy (2) dissipate, authentic Qi manifests. The disappearance of liver Yin strengthens liver Qi (3), while the depletion of heart Yin allows lung fluids (9) to enhance heart Qi. These transformations serve as crucial milestones in the Neidan cultivation process.

This passage elucidates the cultivation principles of "Seven Returns and Nine Revolutions" (qifan jiuzhuan) and the "Golden Elixir and Jade Elixir Cyclic Refinement" (jinye yuye huandan) in Daoist Neidan (internal alchemy) practice.

Regarding "Seven Returns and Nine Revolutions": The "Seven Returns" refers to the process of redirecting heart's Yang Qi back to its origin in the heart, storing it in the Middle Dantian (located at the danzhong acupoint). The "Nine Revolutions" involves transforming the pulmonary Yang Qi originally generated by the heart and returning it to the heart, likewise storing it in the Middle Dantian.

Concerning "Golden Elixir and Jade Elixir Cyclic Refinement": Ancient practitioners believed directing pulmonary fluid (Golden Elixir) to the Lower Dantian (three inches below the navel) constituted Golden Elixir Cyclic Refinement, while channeling cardiac fluid (Jade Elixir) to the Lower Dantian was called Jade Elixir Cyclic Refinement. However, Zhongli Quan pointed out this understanding was incomplete.

True Golden Elixir Cyclic Refinement involves: Using pulmonary fluid as the medium for nurturing the elixir, first cultivating the "Great Medicine" in the Yellow Court (Middle Dantian), then drawing pulmonary fluid from behind the elbow upward to the Upper Dantian (between the eyebrows), descending it back to the Middle Dantian, before finally returning it to the Lower Dantian—completing a full cycle.

Jade Elixir Cyclic Refinement refers to: Kidney fluid ascending with primordial Qi to the heart, accumulating into "golden water" that fills the mouth cavity (Jade Pool), transforming into jade blossoms and white snow. If retained, this essence can nourish the "embryonic immortal" when channeled from Middle to Lower Dantian; if circulated from Middle Dantian to the limbs, it can transmute the ordinary body. This continuous cyclical process constitutes Jade Elixir Cyclic Refinement.

The essence of cyclic refinement lies in Yin-Yang transformation: When Yang emerges from Yin—with true Yin water contained within Yang—its ascent with Yang Qi constitutes "Yin returning as Yang elixir." When Yin emerges from Yang—with authentic Yang Qi contained within Yin—its descent with Yin Qi forms "Yang returning as Yin elixir." Through methods like brain nourishment, crown refinement, elixir calcination, and fire advancement, practitioners achieve cyclic energy transformation among the three Dantian fields.

Ultimately, through the inverted interplay of Five Phases and repeated energy exchanges among the three Dantian fields, the physical form gradually transforms into Qi, and Qi refines into Shen (spirit). The cultivation process progresses from Lower to Middle to Upper Dantian, finally bursting through the Heavenly Gate (baihui point at the crown) to shed the mortal body and attain immortality. Once this bottom-to-top ascension is complete, the practice of "cyclic refinement" becomes unnecessary.

Lü Dongbin asked: "I have already comprehended the principle of the Reverted Elixir (the core method of Neidan practice), but could you explain the theory behind 'refining the physical form'?"

Zhongli Quan replied: "Human life consists of both physical form and spirit. The spirit is the ruler of the physical form, while the physical form serves as the dwelling place of the spirit. Within the body, essence (Jing) generates Qi, and Qi in turn nourishes the spirit (Shen); bodily fluids produce Qi, which then transforms into new fluids—this represents the mother-child generative relationship within the physical form.

This follows the same principle as the Five Phases (Wood, Fire, Earth, Metal, Water) mutual generation: Water begets Wood, Wood begets Fire, Fire begets Earth, Earth begets Metal, and Metal begets Water. The movement of Qi follows this mother-child generative pattern, while the flow of bodily fluids harmonizes like the complementary interaction of husband and wife in Yin-Yang dynamics. Water transforms into bodily fluids, fluids transform into blood, and blood transforms into vital humors—all these are instances of Yin being nourished by Yang to generate new substances. When Yin and Yang become imbalanced, abnormal secretions like mucus, tears, saliva, and sweat appear, indicating that Yin has lost its normal generative function.

Qi transforms into essence (Jing), essence transforms into the luminous pearl (a Neidan term), the pearl transforms into mercury (a Neidan metaphor for the original spirit), and mercury further transforms into cinnabar (the Golden Elixir)—these represent Yang achieving completion through cooperation with Yin. When Yin and Yang are imbalanced, it leads to suffering through illness, aging, and death, showing that Yang cannot attain fulfillment. Yin cannot grow without Yang, nor can Yang achieve completion without Yin. How then can spiritual cultivators focus solely on refining Yang without cultivating Yin, or concentrate on mercury (original spirit) while neglecting lead (original essence)?

At the moment of conception, the primordial Qi of parents combines to form the embryo. Essence and blood create the fetal membrane, which resides in the mother's purely Yin womb. Yin generates Yin, constructing the physical form according to its pattern. Though a fully developed fetus eventually appears as a dignified six-foot body, its fundamental nature remains essentially Yin, containing only a single spark of original Yang Qi.

To attain immortality, one must refine the physical form to prolong earthly existence; to transcend the ordinary and become a sage, one must transform the physical body into Qi, achieving the state of having a body beyond the body. There are two methods for refining the form: The superior method transforms the tangible body into intangible Qi, thereby transcending worldly existence to become a sage. The ordinary method uses the physical form to retain original Qi while employing Qi to nourish the body—this can modestly extend lifespan or greatly prolong earthly existence, enabling the aged to regain youth and the young to maintain vitality, with a potential lifespan reaching 360 years."

This passage expounds the profound correspondence between the human body and cosmic patterns in Daoist cultivation. The human form embodies the operating principles of heaven and earth:

A human embryo takes three hundred days to fully form in the womb. After birth, it requires five thousand days (about 13.7 years) for Qi and blood to become fully abundant. The standard height of five chi five cun (approximately 1.83 meters) corresponds to the numerical principles of the Five Phases (Wuxing). Though individuals vary in stature, all body proportions follow specific measurements: the distance from heart to kidneys is eight cun four fen, as is the measurement from heart to the first laryngeal ring (the "Heavy Tower" referring to the throat area), and again from throat to crown of the head. The total length from kidneys to crown measures two chi five cun two fen (about 76 cm).

The body's primordial Qi (innate life energy) completes 360 celestial circuits in one day-night cycle. Each full circulation equals eighty-one zhang (about 243 meters) of Qi movement, corresponding to the pure yang number of nine times nine. The heart-kidney distance also mirrors the cosmic separation between heaven and earth.

Breathing contains the supreme principles of creation: one inhalation-exhalation cycle constitutes a "respiration," with normal humans experiencing thirteen thousand five hundred breaths daily. Each exhalation releases personal Qi, while each inhalation draws in cosmic Zhengqi (upright energy). Through this respiratory alchemy, practitioners can:

1. Stabilize their life foundation

2. Refine personal Qi through cosmic energy

3. Nourish blood vessels with clear Qi (Rongqi) while using turbid Qi (Weiqi) to protect the body surface

4. Ensure unobstructed meridian flow

5. Develop immunity to temperature extremes and physical exhaustion

6. Ultimately attain the longevity state of bodily lightness and spiritual clarity

Those who maintain this cultivation state may become ageless. Conversely, those with unstable foundations (if the root is not firm) will struggle to achieve these alchemical transformations.

When cultivating the Dao, if one fails to conserve their vital essence (Jing), its depletion will lead to the weakening of primordial Qi (Yuanqi). When the upper Qi dissipates outward while the lower Dantian (a crucial cultivation center in Daoist practice) remains unreplenished, though one may absorb the Qi of Heaven and Earth, this energy disperses majestically across eighty-one zhang (approximately 270 meters). Over time, the primordial Qi becomes damaged, and these energies no longer belong to oneself—instead, they are reclaimed by Heaven and Earth. How then can one seize the righteous Qi of Heaven and Earth for accumulation? The result will be an excess of Yin energy and deficiency of Yang energy, with weakened primordial Qi leading to illness, and its complete exhaustion resulting in death—plunging one back into the cycle of rebirth.

Lü Dongbin asked: "How can one prevent the loss of primordial Qi, and through cultivating the physical form, seize the righteous Qi of Heaven and Earth to achieve immortality?" Zhongli Quan replied: "To win a battle, one needs strong soldiers and sturdy horses; to ensure the people's prosperity, the nation must be wealthy. Here, 'soldiers' refer to primordial Qi. The internal 'soldiers' can eliminate the Yin energy of the physical form, while the external 'soldiers' can seize the Qi of Heaven and Earth. The 'nation' is the self. The tangible body must be abundant and sufficient, while the intangible Qi must remain firm and unyielding. It is like having ten thousand doors constantly open yet never losing anything, or a single horse galloping yet achieving manifold wonders. Advancing and retreating at times is for refining the form; ascending and descending at times is for nourishing Yang energy and eliminating Yin energy. The refinement of Heaven and Earth follows specific timings, and the tempering of Qi and fluids has its fixed moments."

"When refining the form with Jade Liquor (a cultivation term referring to the purest internal fluids), subduing the true Yang Qi (Jia Dragon) within allows one to ascend, making the skin as pure as white snow. When refining the form with Golden Liquor (a higher-level cultivation substance), as the Thunder Chariot (a cultivation term for internal Qi circulation) descends, the chamber fills with golden light." Lü Dongbin said: "I roughly understand the principle of refining the form, but what exactly are Golden Liquor and Jade Liquor?"

Zhongli Quan explained: "When refining the form with Golden Liquor, the bones take on a golden hue, the body emits golden light, and golden flowers naturally manifest in the air—this signifies the return of the Five Viscera's Qi to its origin and the gathering of the Three Yang Qi at the crown. It is an indication of nearing transcendence and the great completion of the Golden Elixir (Jindan). When refining the form with Jade Liquor, the skin radiates a warm, lustrous glow, the body resembling jade trees and jeweled flowers, transforming the mortal frame into a radiant form capable of riding the wind freely, ultimately converting into pure Yang Qi. Though Daoist practitioners may know the methods for refining the Golden Elixir, the work of refining the form should never be underestimated."

"During the process of Jade Liquor's return to the Elixir (a cultivation term for the transformation of essence, Qi, and spirit), one must purify the Embryonic Immortal (the Yang spirit formed through cultivation) as if bathing it, enabling it to ascend. Using the River Chariot (a cultivation term for internal Qi circulation) to circulate through the limbs and bones, begin first with the liver. When the liver is nourished, the eyes will become bright and clear, like lacquer-black dots."

This scripture primarily expounds on two advanced stages of Daoist cultivation—"Jade Liquid Refining the Form" (Yuye lianxing) and "Golden Liquid Refining the Form" (Jinye lianxing)—along with the process of "Facing the Origin" (Chaoyuan).

During cultivation, as the vital essences circulate through different organs, distinct effects manifest: when reaching the heart, numinous liquid (saliva produced during practice) arises in the mouth, transforming into white snow; when flowing to the spleen, the skin becomes smooth as congealed fat with scars vanishing; when entering the lungs, celestial fragrances are perceived and youthful countenance returns; when nourishing the kidneys, the internal elixir returns to its primordial state, immortal music resonates in the ears, and white hair turns black. This constitutes the realm of "Jade Liquid Refining the Form."

"Golden Liquid Refining the Form" represents a higher stage: when the nascent internal elixir first coalesces and merges with the sovereign fire (heart fire), it's termed "Completion of the Crossing" (Jiji); when fully formed and united with true yin, it's called "Refining Substance" (Lianzhi). Through the principles of mutual generation and restraint among the Five Phases, the golden liquid (advanced refined essence) combines with the lunar essence in the spleen-earth, generating purple qi within the heart-fire.

The practitioner kindles true fire within water, dissolves yin-substance within yang-qi, refines the Golden Elixir in the Yellow Court (Dantian), and cultivates the yang-spirit through the qi of the five viscera. Each organ's qi manifests distinctly: liver qi as azure, lung qi as white, heart qi as crimson, kidney qi as black, and spleen qi as yellow—all converging at the middle Dantian to ascend with the sovereign fire.

The pure yang-qi from the lower Dantian, the pure yang-qi from the middle Dantian, and the pure yang-qi of the Great Medicine from the Yellow Court all gather at the upper Dantian. When the five liquids face the lower origin, the five qi face the middle origin, and the three yang face the upper origin—completing the "Facing the Origin" process—cultivation reaches perfection.

At this stage, miraculous signs appear: celestial cranes seem to dance above the head, dragon energies circulate within the body, immortal music lingers in the ears, celestial blossoms rain before the eyes, purple vapors encircle, and divine fragrances permeate. The practitioner transcends mundanity, shedding the mortal husk to become an immortal.

Finally, when Patriarch Lü (Lü Dongbin) inquires about the principle of "Facing the Origin," Patriarch Zhong (Zhongli Quan) replies: As the Great Medicine (internal elixir) nears completion, through the practice of "Jade Liquid Returning to the Elixir," true qi generates and lifts the jade liquid upward, effecting physical transformation—this constitutes "Jade Liquid Refining the Form." Subsequently, through the advanced method of "Flying the Golden Essence Past the Elbow" (a technique guiding golden essence along the Governing Vessel), one ascends to higher realms.

This scripture expounds the advanced Daoist cultivation methods of "facing the origin" (referring to the convergence of Jing (essence), Qi (vital energy), and Shen (spirit) at the crown of the head) and "refining Qi into Shen."

The cultivation process progresses from top to bottom and from inner to outer: first through the "Golden Fluid Returned Elixir" (an advanced Neidan/internal alchemy technique) to refine the golden sand (representing the body's essential substances), causing the Qi of the five organs to gather at the middle Dantian (energy center), then making the three Yang Qi converge at the crown. This goes beyond merely cultivating the physical form for longevity—it aims to refine Qi into Shen, attaining a higher spiritual state.

Lü Dongbin (Lü) inquired of Zhongli Quan (Zhong): "I have already comprehended the great Dao of achieving immortality, grasped the essentials of aligning with celestial timing and perceiving heavenly opportunities. I can distinguish the origins of water and fire (referring to Yin-Yang energies), understand that the dragon and tiger (representing heart-mind and kidney Qi) do not originate from the liver and lungs, and have mastered the profound principles of extraction and replenishment (breathing techniques in Neidan practice). I also recognize that lead and mercury (symbolizing original spirit and original Qi) are not simply equivalent to kan and li (representing water and fire). You've already taught me the crucial methods for circulating cultivation among the three fields (upper, middle, and lower Dantian), and I'm familiar with the principles of refining the returned elixir and transforming the physical form—thoroughly understanding the methods for achieving eternal life. However, regarding the fundamental path of transcending the ordinary to enter sagehood and shedding the mortal form to become immortal—specifically the method of refining Qi to face the origin—I still hope for your further guidance."

Zhongli Quan replied: "The great Dao originally has no concrete form. Tracing its source, it begins as an undifferentiated chaotic state (called 'great simplicity'). Later, the clear Qi ascended to form heaven while the turbid Qi descended to form earth. After heaven and earth separated, each of the five directions (east, south, west, north, and center) had its own Celestial Emperor, each with two children representing the Yin and Yang energies. The interaction of Yin and Yang gave birth to the Five Phases (metal, wood, water, fire, earth), whose mutual generation and restriction subsequently formed the six Qi (three Yin and three Yang energies)."

At the initial moment of conception in the mother's womb, the essence (Jing) and Qi are originally an undifferentiated whole. As the embryo develops, this vital energy gradually divides to form the paired kidneys: the left kidney belongs to the "Mysterious" (Xuan, representing yang energy), generating primordial Qi that ascends to nourish the liver; the right kidney belongs to the "Feminine" (Pin, representing yin energy), receiving fluids that descend to nourish the bladder. Though these Mysterious-Feminine kidneys appear as physical forms, they actually originate from emptiness—the condensation of parents' innate true Qi in the realm of pure yin. Thus the Daode Jing states: "The valley spirit never dies—this is called the Mysterious Feminine"—this gate of Xuan-Pin is like the root of heaven and earth.

From these two kidneys gradually emerge the five viscera and six bowels: the liver corresponds to Wood and the Green Emperor of the East (one of the Five Directional Deities), associated with the Heavenly Stems Jia and Yi; the heart corresponds to Fire and the Red Emperor of the South (Bing and Ding); the lungs to Metal and the White Emperor of the West (Geng and Xin); the spleen to Earth and the Yellow Emperor of the Center (Wu and Ji); the kidneys to Water and the Black Emperor of the North (Ren and Gui). In the early embryonic stage, humans have no physical form—only yin and yang energies exist—until the intestines and stomach take shape, differentiating into six Qi movements (three yin and three yang).

Cultivating the Dao first requires understanding the principle of mutual containment between yin and yang: yang contains yin, and yin contains yang. Further, one must comprehend the profound interactions of the Five Phases: Water contains Fire (like the life-gate fire in the kidneys), Fire contains Water (as heart fire descends to nourish kidney water), Water contains Metal (kidney water nourishing lung metal), Metal contains Water (lung metal generating kidney water), Wood contains Fire (liver wood generating heart fire), and Fire nurtures Earth (heart fire warming spleen earth). These energies intermingle within the body, transforming yin-yang duality into six Qi movements, with the great Dao manifesting as the cyclical operations of the Five Phases.

Just as when yang energy first emerges after the winter solstice, though spring vitality appears simultaneously across all five directions, it is primarily governed by the Green Emperor (spring deity), assisted by the other four directional emperors—if the Black Emperor (winter deity) doesn't withdraw his cold authority, spring warmth cannot manifest; if the Red Emperor (summer deity) doesn't prepare in advance, spring warmth cannot transition to summer heat. Similarly, after the summer solstice when yin energy gradually arises, all five celestial regions begin cooling... (original text incomplete, describing the coordinated functions of the Five Directional Deities during seasonal transitions)

This scripture explains how to grasp the patterns of Yin-Yang transformation during Neidan (internal alchemy) practice. When the Yellow Emperor (symbolizing the body's innate primordial Qi) assists cultivation, if autumn's Yang energy fails to circulate smoothly and the Red Emperor (ruler of summer) doesn't restrain the summer heat, cool weather cannot emerge. If the Black Emperor (ruler of winter) isn't prepared, the coolness won't transition into winter's chill. At the winter solstice, Yang energy ascends from beneath the earth, while at the summer solstice, Yin energy descends from heaven into the earth. Practitioners must understand this principle and apply it in daily life: when the first stirrings of Yang energy arise within the body, the Jing (essence) of the five organs gathers at the middle Dantian (the chest center); when the first stirrings of Yin energy emerge, the fluids of the five organs collect at the lower Dantian (below the navel). The Yang within Yin, the Yang within Yang, and the Yang at the convergence of Yin and Yang—these three Yang energies surge upward to the inner chamber at the crown of the head (upper Dantian), causing the Shen (spirit) to return to the celestial palace (the original spirit's rightful place). This is the meditative state known as "facing the origin" (chaoyuan).

Lü Dongbin asked: During ordinary cultivation, when Yang energy arises and the Qi of the five organs gathers at the middle Dantian, when Yin energy arises and the fluids of the five organs collect at the lower Dantian, and when the three Yang energies converge at the upper Dantian—these foundational practices are widely known. But how can one truly transcend the mundane? Zhongli Quan replied: For ordinary people, when Yang energy arises and Qi gathers at the middle Dantian, or when Yin energy arises and fluids collect at the lower Dantian, this is merely basic cultivation and cannot lead to transcendence. To attain immortality, one must first accomplish the "dragon-tiger copulation" (the union of heart-fire and kidney-water) to refine the Golden Elixir. Once the Golden Elixir is formed, it generates true Qi. At this stage, timing and heat regulation are crucial: follow the annual cycle for monthly waxing and waning, the monthly cycle for auspicious and inauspicious days, and the daily cycle for breath timing. When nourishing Yang energy with pure Yang, avoid mixing in Yin; when refining Yin energy with Yang, prevent the Yin from dispersing. The seasonal waxing and waning of the organs follows this pattern: in spring, the liver is strong while the spleen is weak; in summer, the heart is strong while the lungs are weak; in autumn, the lungs are strong while the liver is weak; in winter, the kidneys are strong while the heart is weak. Though the kidneys are the body's foundation, during the last eighteen days of each season when the spleen is strong, kidney Qi is at its weakest—this is when many illnesses arise. During practice, note these precautions: on Jia-Yi days (associated with Wood), when liver Qi is dominant, guard against spleen Qi stagnation; on Bing-Ding days (associated with Fire), when heart Qi is dominant, prevent lung Qi deficiency.

This passage explains the essential principles governing the Qi circulation of the five viscera (heart, liver, spleen, lungs, kidneys) and their cultivation practices. Each organ's Qi follows specific active cycles: Heart Qi germinates during the Hai hour (9-11 PM), grows during Yin hour (3-5 AM), peaks at Si hour (9-11 AM), and declines at Shen hour (3-5 PM). The liver, lungs, and kidneys each have their corresponding temporal patterns. Spleen Qi follows seasonal rhythms—aligning with liver Qi in spring, heart Qi in summer, lung Qi in autumn, and kidney Qi in winter. Illness often arises when people remain unaware of these cyclical waxing and waning patterns of Qi.

The key to cultivation lies in maintaining Yin-Yang equilibrium: When Yang Qi gathers, one should refine it to prevent Yin Qi from emerging; when Yin Qi accumulates, one must nourish Yang Qi to prevent its dissipation. After the primordial Qi (innate vital energy) is generated, use pure Yang Qi to refine the Qi of the five viscera, keeping the breath in its authentic state. The specific practice involves first transforming the Yin Qi in the kidneys until the energy channels become as calm as nine tranquil rivers. Next, dissolve liver Yin until all bodily gates permanently close. Then refine lung Yin to fuse metal (lungs) and fire (heart). Finally, transform spleen Yin to secure the "Jade Portal" (Dantian). When true Qi ascends and the Qi of the four viscera merges into one, even if golden fluid (kidney Jing) descends, it would be like trying to extinguish a cartload of burning firewood with a cup of water.

When water (kidney) and fire (heart) energies harmonize and enter the "Divine Palace" (upper Dantian), stabilize the breath in inner observation while maintaining focused intent to enter a wondrous state. In this stillness, one may hear celestial music as if in a dreamlike trance, transported to an ethereal immortal realm. The visions of jade towers, pearl-adorned palaces, and silken splendors far surpass worldly magnificence—these are signs of the Yang spirit (Yang Shen) beginning to coalesce. Ultimately, when the Yang spirit returns to the upper Dantian (Niwan Palace), the practitioner can break through the "Celestial Gate" (crown point) to manifest the Dharma body amid golden light, achieving unity with the Dao.

This passage discusses the Daoist cultivation methods of "inner observation" (neiguan) and "refining the form" (lianxing). Practitioners sit upright in quiet surroundings, transforming vital Qi through specialized breathing techniques (fetal breathing). Upon reaching a certain level of attainment, the body feels light as if walking through air, with arms moving freely, ultimately achieving the state of form and spirit uniting as one.

The immortals Zhongli Quan and Lü Dongbin here discuss key cultivation principles: ordinary people who don't comprehend the profound mechanisms may accumulate pathogenic Qi by forcibly practicing fetal breathing. Authentic cultivation should first refine the physical form to prolong life, then refine Qi to seek immortality. Qi refinement requires selecting specific years, months, days and hours while eliminating distracting thoughts in a quiet chamber. If the mind remains unsettled with wild thoughts, cultivation effects cannot be achieved.

Regarding inner observation methods, the text explains this involves closed-eye meditation to examine one's internal landscape. However, practitioners must avoid attachment to concrete imagery (the "monkey mind and horse will"), lest they lose their purpose amid phenomena. True inner observation requires achieving "sitting in forgetfulness" (zuowang) — ears not listening, eyes not seeing, and the inner mind free from turbulence. Unfortunately, many beginners misunderstand the timing and methods, mistakenly believing mere imagination can produce the Golden Elixir (jindan) or medicinal substances. This is as impractical as fantasizing about tangible sun-moon or formless heaven-earth.

The mentioned "Ten Continents" (shizhou), "Purple Mansion" (zifu), and "Three Isles" (sandao) are all legendary Daoist celestial realms, while "Great Tenuity True Lord" (Taiwei Zhenjun) oversees immortal registers. Accomplished cultivators may shed their mortal husks to verify their merits at these sacred realms and receive immortal ranks.

When practicing cultivation, merely focusing one's intention in the belly is like a child playing games. True masters understand "sitting in oblivion" (zuowang, a state of deep meditative stillness) and "visualization" (cunxiang, concentrating Qi and spirit by contemplating specific images). But if these methods are misapplied, it's like picking up money in a dream that can't be spent, or drawing a cake on the ground that can't satisfy hunger—ultimately, it's all flowers in a mirror or the moon reflected in water, an empty pursuit.

Yet this approach has its merits, for the human mind is prone to fluctuation, and a single thought is the hardest to subdue. When gathering Qi for cultivation at the proper hour, even if one knows to choose a tranquil place, the mind is often entangled with distractions, and the will swayed by emotions. Time flashes by like lightning—every moment is precious, and the slightest misstep can lead to vastly different outcomes. Some practice for years without results, and the problem lies in scattered thoughts and agitated intentions. It's like someone absorbed in a painting who notices only the beauty of the pigments but fails to see Mount Tai, or someone engrossed in music who hears only the strings and flutes but misses the thunder—human sensory capacity is inherently limited, let alone trying to perceive heaven and earth with a single mind.

When applying cultivation methods at the right moment, how can one not rely on visualization and inner observation (neiguan, guiding internal energy through specific imagery) to achieve success? Someone might ask, how exactly does one practice visualization? When Yang Qi ascends, one may visualize masculine figures, dragons, flames, the sky, clouds, cranes, the sun, steeds, mist, rosy clouds, chariots, flowers, and clear Qi. When Yin Qi descends, one may visualize feminine figures, tigers, flowing water, the earth, rain, turtles, the moon, oxen, springs, soil, boats, and leaves.

The Daoist tradition often speaks of the Azure Dragon, White Tiger, Vermilion Bird, and Black Tortoise (the Four Directional Guardians)—these names must be visualized as concrete forms during cultivation. The Five Sacred Peaks, the Nine Provinces, the immortal realms of the Four Seas and Three Isles, golden boys and jade maidens, the "River Chariot" (the circulation of internal Qi), and the "Multi-Storied Tower" (the throat passage)—all can be named through analogy to establish objects of visualization. Just as one shouldn't discard fishing gear before catching a fish, or abandon a snare before trapping a hare, cultivation first requires establishing these visualized forms to stabilize the spirit. It's like a following cart needing to move along the tracks laid by the one ahead.

When cultivation reaches a certain level and internal practice has taken form, the method of inner observation (a meditative technique for calmly examining one's inner state) becomes crucial. This inner observation should neither be clung to obsessively for extended periods nor abruptly discontinued. Only when one achieves a state completely free from distracting thoughts can this be considered true purity of mind.

This genuine purity of mind represents the realm of "true emptiness." Attaining this state allows gradual transcendence of worldly dust and movement toward radiant clarity. In the initial stages of practice, practitioners may employ visualization techniques (imagining specific forms) as aids. However, as cultivation deepens, the methods should become increasingly simplified until one can enter the realm of serene emptiness through inner observation alone.

Ancestor Lü (Lü Dongbin) asked: "When using the dragon-tiger coupling (symbolizing yin-yang harmonization) to match yin and yang, how exactly should one visualize this process?"

Ancestor Zhong (Zhongli Quan) replied: "In the initial stage of harmonizing Kan (Water trigram) and Li (Fire trigram) through yin-yang union, visualize it thus: The Nine Emperor True Being (representing yang) ascends carrying a child in red (symbolizing wood-fire qi), while the Nine Emperor True Mother (representing yin) descends carrying a girl in black (symbolizing metal-water qi). They meet before the Yellow Chamber (middle dantian) without entering, guided by an old woman in yellow (symbolizing breath regulation), their joyful encounter resembling earthly marital union. Subsequently, the girl descends (qi settling into the dantian) while the boy ascends (qi rising upward), mirroring human separation. Finally, the old woman holds up a red-orange object resembling a tangerine and casts it into the Yellow Chamber, containing it in a golden vessel."

In this process, the boy represents Qian (Heaven, yang) seeking from Kun (Earth, yin), with yang qi returning to its origin while carrying yin qi to meet. The girl represents Kun seeking from Qian, with yin qi returning to its origin while carrying yang qi to meet. This constitutes the visualization method for Kan-Li interaction and yin-yang matching.

An alternative visualization method: Within roaring flames appears a black tiger (metal-water) ascending, while amidst surging waves appears a crimson dragon (wood-fire) descending. These two sacred beasts meet and engage in combat before a pavilion. At this moment, vermilion gates open wide, and through billowing smoke and flames emerges a royal figure (symbolizing the original spirit).

This passage describes two crucial visualization methods in Daoist Neidan (internal alchemy) practice: the "Dragon-Tiger Copulation" and the "Advancing Fire Refinement."

The "Dragon-Tiger Copulation" visualization begins with imagining raging flames between heaven and earth (symbolizing the rising Yang Qi condensing into "yellow sprouts," the nascent elixir), while towering waves appear above (representing Metal-Water Qi). The flames surge upward then descend, filling the cosmos. Practitioners then visualize the Azure Dragon and White Tiger (symbolizing Yin-Yang energies) spiraling around each other (corresponding to breathing rhythms), eventually merging into a golden vessel that sinks into the lower Dantian (the "Yellow Chamber"). This process resembles storing an elixir in a sealed crucible, where the dragon-tiger union generates the "yellow sprouts" of embryonic elixir.

The "Advancing Fire Refinement" visualization involves imagining a cauldron-like vessel guarded by the Four Symbols (Azure Dragon, White Tiger, Vermilion Bird, and Black Tortoise). A minister in purple robes (symbolizing "minister fire") and servants adding fuel (representing "commoner fire") stand nearby. Then appears a crimson-clad monarch (the practitioner's original Shen/spirit) riding a red horse upon fiery clouds, commanding the intensification of flames. The fire surges upward to impact the Niwan Palace (cranial chamber) at the crown, then rebounds downward, creating a cyclical flow. All figures and objects become enveloped in flames as the vessel's contents condense, with luminous pearls emerging in the liquid. This constitutes the visualization of refining the elixir through fire.

The passage concludes with advanced "Golden Fluid Returned Elixir" imagery: celestial flowers rain down amid auspicious clouds as jade maidens (symbolizing purified energies) offer divine nectar (the golden elixir). These visualizations serve as transformative methods for refining Jing (essence), Qi (vital energy), and Shen (spirit) in Neidan practice, using specific imagery to guide and sublimate internal energies.

This scripture describes the mystical visions that arise during the practice of Daoist Neidan (internal alchemy—the method of achieving immortality through refining Jing (essence), Qi (vital energy), and Shen (spirit)). These visions belong to different stages of "Cunxiang" (a cultivation technique involving visualization through focused intent).

When the Golden Elixir first takes form, the practitioner may witness dragons and tigers (symbolizing the two energies of Yin-Yang) pulling a chariot through fire, ascending to break through the Three Passes (key acupoints: the coccyx, the spine, and the jade pillow). Each pass is guarded by celestial soldiers and generals, creating an awe-inspiring scene. Initially, the dragons and tigers fail to break through, but after being refined by intense flames, they finally pass, halting only at the Kunlun (the crown of the head) and the Heavenly Pool (the upper Dantian). Sometimes, three immortal cranes may be seen soaring through the three heavens, or two butterflies entering the three Dantian, or a child in red robes carried by five-colored auspicious clouds through the Heavenly Gate, or a golden chariot and jade carriage bearing an emperor beyond the Three Realms. These are all visions that appear during the practice of "elbow-flying golden essence" (a method of circulating vital energy) and the "Great River Chariot" (the cyclical movement of Qi).

Next, a red-robed envoy may appear, riding a chariot to tour the Nine Provinces (ancient divisions of China), starting from Jizhou and circling through all regions before returning—symbolizing the circulation of internal Qi within the body. At times, the practitioner may witness journeys to the Five Sacred Mountains (the five great peaks), beginning with Mount Heng, or boating across the Five Lakes (the five great lakes), starting from the Northern Marsh, or celestial decrees summoning the Five Thearchs of the directions. These are all manifestations of the "Returning Elixir" stage (the phase of refining the Golden Elixir).

At more advanced stages of cultivation, visions such as scattered pearls and jade, nourishing rain and dew, surging ocean tides, the rise of Yang energy, flames filling the sky, and mist enveloping the world may appear—these are signs of "refining the physical form" (the stage of transforming the body). In the final phase, one may see immortal cranes leaving their nests, divine dragons emerging from caves, the Five Thearchs paying homage to the Celestial Emperor, riding a crimson phoenix to ascend to the heavens, celestial flowers descending, and divine music resounding—these are the visions of "paying homage to the Primordial" (the audience with the Celestial Worthy of Primordial Beginning). After completing these stages, the practitioner no longer relies on deliberate visualization, entering instead the state of "inner observation" (serene contemplation of the internal realm).

When Lü Dongbin (one of the Eight Immortals of Daoism) inquired about the profound principles of inner observation, Zhongli Quan (a Daoist patriarch) replied: "Throughout history, those who cultivate the Dao but fail to comprehend the mysteries of celestial mechanisms, or who practice incorrectly while seeking instant success, will find it difficult to attain true accomplishment."

This passage discusses the Daoist practice of "inner observation" (neiguan) and the potential demonic obstructions encountered during cultivation. Practitioners enter meditative states by reducing breath and closing their eyes in contemplation, during which yin spirits (impure versions of primordial spirit) may appear—yet these are not the true yang spirit (the pure yang immortal). Authentic transcendence requires progressing through stages: gathering the medicinal essences (harvesting internal Jing and Qi), applying the fire phases (regulating the energetic temperature), extracting lead and adding mercury (harmonizing yin and yang), and finally returning the elixir (refining the Golden Elixir).

Inner observation practice follows no fixed temporal rules, demanding day-and-night upright sitting in a quiet chamber to distinguish the yang spirit while expelling yin ghosts. Like Bodhidharma facing his wall for nine years or the Buddha's six-year meditation before breakthrough, this method represents an exceptionally arduous path. During practice, celestial palace illusions may arise—visions of wealth, delicacies, and luxuries—all mental projections. Mistaking these for reality leads to attachment, preventing liberation and even inviting deception by yin ghosts and external demons that divert practitioners onto heterodox paths.

The text specifically mentions the "Three Corpses and Seven Po" (malevolent spirits within the body) and "Nine Worms and Six Thieves" (various desires) that actively obstruct cultivation, rejoicing in practitioners' failures. Patriarch Lü (Lü Dongbin) ultimately clarifies that through inner observation, one must coalesce the yang spirit, refine the primordial spirit to break through the inner court (upper Dantian), and finally ascend through the celestial gate (Baihui point at the crown) to attain the Dao. The entire passage emphasizes that inner observation—requiring both perseverance and vigilance against illusions—constitutes the essential method for transcending mundanity to enter sagehood.

This passage discusses the various obstacles and trials encountered on the path of Daoist cultivation toward immortality. It begins by describing advanced stages of practice: when one reaches profound levels of attainment, they may freely traverse different dimensions ("the sage can enter and exit without distinction"), arriving accurately regardless of distance ("coming or going, far or near, without error"). Those wishing to remain in the human world maintain unity of spirit and form ("to dwell in the world, Shen unites with the body"), while those seeking transcendence may ascend to the Penglai Isles ("to rise as an immortal, journeying afar to Penglai"). However, complete cultivation requires accumulating three thousand merits ("fulfilling three thousand merits") and attaining liberation through inner observation ("achieving transcendence through Neiguan [inner vision]").

Zhongli Quan (one of the Eight Immortals) emphasizes that cultivators must first develop unwavering faith ("initiate resolute confidence"), remaining unmoved by worldly attachments such as affection, fame, or profit ("not allowing mundane matters like love, fame, or material pursuits to shake their great resolve"). Next comes enduring hardship ("then develop steadfast endurance"), maintaining their original aspiration even in impoverished or solitary conditions ("not altering their initial determination despite austere environments of poverty and solitude"). Those with insufficient resolve may only achieve moderate accomplishments ("stopping at middling attainment") or minor achievements ("halting at minor realization"). Worse still are those who misunderstand the true Dao ("fail to recognize the great Dao"), studying petty methods and heterodox paths ("practicing minor techniques while indulging in deviant paths"), wasting their years ("letting time slip away"), only to decline in old age and re-enter the cycle of rebirth ("in later years declining and falling back into samsara"). This leads subsequent cultivators to dismiss teachings of longevity and liberation ("considering immortality deceitful and transcendence empty words"), lacking conviction even when hearing the true Dao ("hearing the Dao yet not believing"), ultimately failing to overcome demonic obstacles ("the Ten Demonic Trials and Nine Difficulties").

When Lü Dongbin (another renowned Daoist immortal) inquires about the "Nine Difficulties," Zhongli Quan elaborates: The first difficulty concerns basic survival needs ("clothing and food press urgently")—before completing the elixir, one still faces cold, heat, and hunger ("before the Great Medicine is achieved, enduring seasonal extremes; before true Qi arises, still experiencing hunger and thirst"). The second is obstruction by elders ("hindrance from respected superiors")—even finding time for practice proves challenging ("snatching moments of leisure yet constrained by elders"). The third involves familial bonds ("entanglement of love and affection")—family ties become shackles ("the manacles of kindness, the stocks of emotion"), with worldly worries constantly disturbing serenity ("the fiery courtyard of sorrows never ceasing"). The fourth is ensnarement by fame and profit ("shackles of reputation and gain")—the wealthy remain insatiable ("rich enough to possess ten thousand households, noble reaching the highest ranks, yet deluded minds refuse momentary rest"). The fifth concerns youthful weakness ("youth unwilling to cultivate due to weak Qi"), missing the prime time for practice. These difficulties all hinder the cultivator's progress.

On the path of cultivation, there are nine common obstacles that hinder spiritual progress. The first is a stubborn and unyielding mindset—utterly lacking self-reflection or awakening, persistently acting through dark means. The consequences manifest in this very life, bringing suffering not only to oneself but also to future generations. This is the first peril that practitioners must beware of.

Some fixate too heavily on the great matter of life and death, rushing to seek guidance from teachers without discerning authenticity. Some are deceived by eloquent speakers, others by pretentious appearances, initially mistaking them for immortals, only to later discover they are frauds seeking personal gain. This danger of being misled by false teachers is the sixth peril practitioners must guard against.

Others follow blind masters and arrogant companions, receiving misguided instruction in heretical paths. Like plucking leaves while neglecting the roots, they ultimately fail to align with the true Dao (the Way). These petty techniques and deviant methods boast among themselves, unaware that the genuine Dao is like the sun and moon—when they appear, they illuminate the world—or like thunder—when it sounds, it shakes the heavens. How can the faint glow of fireflies or the croaking of a frog in a well compare to the radiance of the sun and moon or the power of thunder? This seventh peril involves being misled by erroneous teachings.

Some resolve to cultivate in the morning but change their minds by evening; they contemplate diligence while sitting but forget upon standing. Momentary enthusiasm brings joy, yet it is difficult to sustain; they begin with vigor but end in laziness. This lack of steadfastness and tendency to abandon the path midway is the eighth peril practitioners must avoid.

Others waste their days, letting months and years slip by without true cultivation. In youth, they cling to fame and wealth; in old age, they fret over descendants. One must understand that human life is finite—do not always say, "There is next year after this one." The world is impermanent—do not assume, "There is tomorrow after today." If today cannot even be guaranteed, how much less can tomorrow be known? How can old age reclaim the time of youth? This ninth peril—the fault of squandering precious time—must be guarded against. Only by overcoming these nine obstacles can one truly embark on the path of cultivation.

Lü Dongbin asked: "Having understood the nine difficulties in cultivation, could you explain the so-called ten demonic obstacles?"

Zhongli Quan replied: "The ten demonic obstacles fall into three categories: first are temptations in waking life, second are disturbances in dreams, and third are illusions arising during meditation.

Specifically: When dazzling flowers appear before your eyes, celestial music fills your ears, your tongue craves delicacies, your nose longs for exotic fragrances, and you feel intoxicated by sensory pleasures - recognize this as the Thief Demons (referring to the six sensory desires of sight, hearing, smell, taste, touch, and thought). When you see golden palaces, treasures strewn across the land, or halls filled with silver and gold, identify this as the Wealth Demon. When visions of noble steeds, high-ranking officials with generous salaries, or entire households basking in glory appear, beware the Authority Demon.

Sudden weather changes - whether serene sunshine or violent thunderstorms - or unexpectedly hearing sounds of celebration or lamentation, these are the Emotion Demons (disturbances from joy, anger, sorrow, pleasure, love, hatred, and desire). When illusions show family members meeting misfortune or households destroyed, understand this as the Kinship Demon. Imagining disasters like fires, falling off cliffs, or poisonous insect bites constitutes the Calamity Demon.

During meditation, if you see high deities (such as the Three Pure Ones or the Jade Emperor) manifesting, beware the Sage Demon. Hallucinations of armies clashing with flashing blades represent the Weaponry Demon. Visions of celestial maidens playing music, dancing, or urging you to drink constitute the Lust Demon.

All these demonic obstacles are illusions testing your resolve on the cultivation path. The key lies in maintaining clarity of mind without attachment to what is seen or heard."

This passage discusses the various demonic obstructions (魔障) encountered during spiritual practice, particularly the "Ten Demons" (十魔) of sensual desire. When practitioners encounter beautiful appearances and become attached or develop obsessive thoughts, they fall into demonic obstruction. The key lies in maintaining clarity of mind and not being deluded by superficial appearances.

True Dao cultivators remain unattached and unwavering when facing external temptations. Even when encountering illusions during dreams or meditation (内观), they must discern truth from falsehood and avoid being carried away by these phenomena. One must use the "true fire" (真火 - the internal heat generated during practice) to burn away delusional thoughts, and employ the "Purple River Chariot" (紫河车 - a cultivation term referring to the pathway of Jing-essence and Qi circulation) to transport the "yang spirit" (阳神 - the cultivated primordial spirit), thereby transcending these obstructions.

Throughout history, many cultivators have struggled to overcome the "Ten Demons and Nine Difficulties" (十魔九难) despite their sincere practice. Some recluses who withdraw from society still fail to completely eliminate these obstacles. While such practitioners may attain certain achievements—such as becoming Human Immortals (人仙) or Earth Immortals (地仙, preliminary stages of Daoist attainment)—only by thoroughly conquering all demonic challenges can one cultivate the yang spirit and ascend to the immortal realms.

Later, Zhongli Quan (钟离权, one of the Eight Immortals) responds to Lü Dongbin's question by explaining: When some practitioners diligently cultivate without visible results, the fault lies not with the Daoist methods but rather in their lack of guidance from an enlightened master (明师). The cultivation process requires understanding the depth of practice, proper timing for method transitions, and verification standards for each stage of progress.

This passage discusses potential challenges in cultivation practice and the concrete manifestations that verify progress. If practitioners follow correct methods yet see no results, the issue lies not with the Daoist methods themselves, but in failing to grasp the proper timing. When guided by an enlightened master and practicing in accordance with seasonal rhythms, natural verification signs will appear.

Lü Dongbin asked: "How many cultivation methods exist? And how should one discern the proper timing?"

Zhongli Quan replied: "There are twelve primary cultivation methods: First, harmonizing Yin-Yang; second, blending water and fire; third, the dragon-tiger congress (referring to balancing the body's Yin and Yang energies); fourth, elixir refinement; fifth, 'flying golden essence behind the elbow' (a method for transforming Jing into Qi); sixth, 'jade nectar returning to the elixir' (a Neidan practice); seventh, refining the form with jade nectar; eighth, 'golden nectar returning to the elixir'; ninth, refining the form with golden nectar; tenth, morning primordial Qi refinement; eleventh, internal observation and exchange (witnessing internal energy transformations through inner vision); twelfth, transcendent form separation (achieving the state of Yang spirit projection).

The timing of cultivation must follow cosmic patterns: annually, it should accord with the rising and falling rhythms of Yin-Yang; monthly, it follows lunar phases; daily, one must observe the four cardinal hours (midnight, noon, sunrise and sunset), Bagua directions, heavenly stems and earthly branches, and hourly divisions. From initial practice to ultimate immortality, every stage's verification signs will appear with perfect precision."

The text then details various verification signs appearing during cultivation: first, lustful thoughts completely vanish while external behavior becomes impeccably virtuous; during "herb gathering" (collecting primordial Qi), golden essence fills completely; with purified mind-state, one subdues Yin ghosts; when heart-fire rises, sweet saliva naturally forms in the mouth; Yin-Yang energies interact vigorously within the abdomen, producing constant thunder-like sounds; unsettled hun and po souls cause frequent nightmares; minor ailments in organs or limbs heal spontaneously without medicine; the Dantian stays warm at night while days bring mental clarity; divine light appears naturally in dark rooms; dreams become fearless and heroic; sometimes dreaming of holding an infant (symbolizing nascent inner elixir); semen retention becomes absolute; sudden joint openings accompanied by profuse sweating; mouth fluids congeal like cream; spiritual liquids transform into unguent; gradual aversion to meat and strong flavors; mortal bones lighten as the Yang spirit can outrun galloping horses; no greed arises toward external phenomena; genuine Qi can heal others; internal vision clearly observes bodily landscapes. These signs manifest sequentially, marking progressive stages of cultivation.

This passage describes the wondrous physical and spiritual transformations that occur when a Daoist practitioner reaches advanced stages of cultivation. At certain milestones of practice, the following signs manifest:

The eyes become brilliantly clear like a child's, the face radi youthfulness with darkening hair and ageless complexion. When inner Qi reaches fullness, one feels satiated with minimal food and remains sober despite copious wine. The skin turns lustrous, the entire demeanor shines with vitality, while the mouth constantly tastes sweetness and emits rare fragrances perceptible to others.

Vision becomes extraordinarily keen, discerning minute details a hundred paces away. Scars and blemishes vanish spontaneously, and the body ceases to produce sweat or tears. Upon attaining fetal respiration (a state of complete Qi circulation), all need for nourishment ceases as the mind achieves pristine clarity, transcending worldly attachments. The nine worms (parasites symbolizing bodily impurities) perish and the three corpses (malevolent spirits representing base desires) dissolve, resulting in dreamless sleep and perpetual spiritual wakefulness.

The physical form transforms into a body of pure Yang, impervious to cold or heat, surpassing the cycle of life and death. During deep meditation, the spirit journeys to the Huaxu celestial realm (Daoist paradise), beholding splendors unseen in the mortal world. When merit reaches completion, one receives authentic Fulu (talismans) from the Three Pure Ones (Sanqing), gaining foresight into Yin-Yang transformations and human fortunes.

At this stage, worldly affairs become distasteful as solitude and quiet cultivation grow preferable. The practitioner can manifest doppelgangers (Yang-spirit projections) and dry mercury with breath's vital energy. Serene sitting summons auspicious light and celestial music. Even when facing nobility, one perceives their mundane essence. The countenance becomes transcendent, bones reveal golden hues, and divine guardians accompany every movement.

The final stages feature extraordinary phenomena: purple mists crowning the head, golden light shielding the body, and the ability to transform into fire dragons or dark cranes (symbolizing Yang-spirit attainment). Shedding the mortal husk completely, one transcends ordinary existence—this constitutes genuine liberation.

The passage depicts a sacred scene: multicolored auspicious clouds swirl amidst an atmosphere permeated with propitious energies, while celestial blossoms drift down from the heavens. Mystical cranes (symbolizing longevity in Daoism) soar in pairs, exotic fragrances diffuse through the air, and jade maidens (celestial nymphs) descend to bestow heavenly scriptures and purple edicts. Upon completing the ritual, the immortals' ceremonial crowns and robes stand fully prepared, their majestic procession forming an awe-inspiring spectacle with countless attendants preceding and following. The assembled host welcomes and escorts one another as they return together to the Penglai paradise (legendary island of immortals).

Within the Purple Mansion (abode of deities), the congregation pays homage to the True Lord of Taiwei (a high-ranking Daoist immortal). This venerable being verifies each individual's registered origins and name, examining the merits of their cultivation practices. Those who pass this evaluation gain residence among the Three Isles (Penglai, Fangzhang, and Yingzhou—the immortal mountains), thereafter being honored as "Perfected Immortals and Transcendent Maidens."

Lü Dongbin (one of the Eight Immortals) speaks: "Today I am profoundly grateful for the Master's revelation of the great principles of Xiyi (the Daoist realm of profound mystery) and the arcane mechanisms of heaven and earth. Not only has this clarified my perception, but it has revitalized my very spirit. My mortal frame now finds its true anchor, spared from decaying like common dust. Yet those who comprehend the Dao may not practice it, and practitioners may not attain realization. Considering the gravity of life-and-death matters and time's swift passage, though I've grasped these mysteries, without actual cultivation I remain no different from the ignorant. I venture to inquire—during the convergence of Yin and Yang, what specific methods should guide our practice? How should one apply effort?"

Zhongli Quan (foremost of the Eight Immortals) responds: "I possess the ten-volume Lingbao Complete Methods, divided into sixteen disciplines. It contains six liturgical formats: first, Golden Edicts (precious celestial documents); second, Jade Texts (sacred scriptures); third, True Origins (the source of Dao); fourth, Parables (illustrative analogies); fifth, Authentic Formulas (genuine oral instructions); and sixth, Essential Dao (core cultivation principles). This classic encompasses the great Dao, drawing upon the teachings of the Three Pure Ones (Daoism's supreme deities), using the ascent and descent of heaven-earth's Yin-Yang as its standard, and the cyclical exchange of solar-lunar essences as its law. Truly it serves as the cultivation manual for Five Types of Immortals and the guideline for Three Achievements. I shall select an auspicious day to transmit it to you."

A later annotator's postscript to Zhong-Lü's Transmission of the Dao reads: Within the Daoist Canon's Great Clarity section (catalogued under "Zhi"), we have indeed discovered the secret transmission of Zhengyang Perfected Being's Lingbao Complete Methods—three volumes comprising ten scrolls. Upon careful study of its language and intent, many passages prove difficult to comprehend, likely challenging for novice practitioners, hence we refrained from full transcription. Should fellow seekers of kindred aspiration encounter this text in their future studies, they will understand my considerations regarding what to transcribe and omit. This annotation was reverently composed by Daoist Gao Shiming of Fuchu, following ritual purification, on the first day of the second lunar month in the second year of the Tianqi era (1622).

This text serves as the epilogue to The Ten Books on Cultivating Perfection: The Zhong-Lü Transmission of the Dao, written by En Hong, styled Zhenghuazi, a lineage descendant of the Pure Yang Perfected Lü Dongbin. It conveys the following essence:

Since ancient times, the fundamental source of all transformations in the universe has been revered as the Dao (the cosmic principle). When the Dao manifests to instruct humanity, it appears as profound truths and the essential methods for cultivating both nature (xing) and life (ming). This scripture originates from the authentic transmission of celestial immortals, containing within its pages all the esoteric principles of cultivation that would emerge in later generations.

Yet ordinary people often interpret it literally, using conventional thinking to speculate on its meaning. Regarding its discussions of the Great Path to immortality, the operations of heaven and earth, the transformations of yin and yang (sun and moon), the cycles of seasons, the mutual generation and restraint of the Five Phases (Wood, Fire, Earth, Metal, Water), the harmonization of water and fire, the coupling of dragon and tiger (yin-yang balance), elixir refinement, the application of lead and mercury (alchemical terms), the methods of extraction and replenishment (cultivation techniques), the revolution of the River Chariot (Neidan terminology), the return of the elixir (cultivation stages), refining form into qi, paying homage to the primordial spirit (Yuanshen), inner observation practice, overcoming demonic obstacles, and verifying spiritual states—they assume these are merely what the surface words describe. In truth, these teachings contain deeper meanings beyond the text, with mystical significance transcending apparent principles; they cannot be reduced to mere verbal expressions.

This scripture is exquisitely profound and subtle, impossible to fully explain through ordinary chapter divisions or punctuation, nor can worldly minds comprehend it. It stands as the foundational text for the Five Patriarchs and Seven Perfected Ones of Daoism, as well as all sages. Having been transmitted since the Tang Dynasty for centuries, it has been venerated and practiced by cultivators. Now, with the complete text newly collated and published under the responsibility of later disciples, these words are specially appended. As for the scripture's profound essentials, the True Lord of Vast Teachings and various patriarchs have already expounded them thoroughly—there is no need for further elaboration here.
