《道法會元》Vol. 4

The fourth volume of Daofa Huiyuan (Collected Essentials of Daoist Methods) records the core principles of the Qingwei lineage (an important Daoist school), primarily elucidating the fundamental theories of cultivation and ritual practice.

The text begins with the concept of "the Primordial Ultimate of Mysterious Origins," referring to the most primordial cosmic energy—the Prenatal One Qi (Xiān Tiān Yī Qì, the fundamental energy that constitutes all existence in Daoist cosmology). Through the dynamic interplay of movement and stillness, this energy generates luminous radiance, forming the operational patterns of the "Great Primordial Dao." The ascending and descending flow of this energy gives rise to all phenomena, with its most refined essence condensing into "Jade Script Inner Meanings" (sacred textual symbols).

Three crucial forms of energy are enumerated: Brahma Qi (pure and uncontaminated energy), Clear Qi (luminous energy), and Radiance Qi (brilliant energy). During practice, one must first burn incense and sit in stillness, gathering the Shen (spirit) through numerological methods like the "Three-Five" system to accumulate energy before inscribing Fulu (talismans and registers, ritual sigils). Fulu are classified into five grades: simple talismans, formal petitions, scriptures, sacred writings, and the Dao itself—each with distinct efficacies.

The key to crafting talismans lies in focused concentration, reaching a state where self and object are forgotten. In this state, one perceives the "Heavenly Authenticity" (original true nature), and the brushstrokes naturally distinguish between clear and turbid Qi, with each stroke emitting golden light. True spiritual power manifests when a single thought summons divine presence—no incantation is strictly necessary for efficacy.

The brush used for talisman inscription must align with Water or Fire attributes: Water brushes are for summoning rain, snow, mist, or treating Yang-afflicted ailments; Fire brushes are for clearing skies, dispelling plagues, or treating Yin-afflicted ailments. The inscription must be completed in a single breath, concluding with the "Three-Character Imperial Command" (specific sacred script) to ensure the Primordial Ancestral Qi accompanies the talisman.

Purification Altar Talismans cleanse ritual spaces and may be burned in air or dissolved in water. When paired with the "Purify Heaven and Earth Incantation" or the names of the Five Directional Celestial Emperors, they dispel impurities of the Five Phases (Wǔxíng) and purify the four directions. Messenger Incense Talismans facilitate communication with deities—"messenger" signifies sincerity, while "incense" represents its fragrance traversing the Three Realms. In emergencies, a "portal mark" (special sigil) may be added, along with reverential phrases like "Your Servant [Name] Humbly Petitions." Crafted on cypress wood or yellow paper, these talismans are burned while silently reciting prayers to specific deities for aid.

The text details the specific methods and precautions for drawing and using talismans (fulu) in Daoist rainmaking rituals and other magical practices.

When drawing rain-summoning talismans, a fixed sequence must be followed: First write the "main talisman" (zhengfu) with one to three characters, applying seven brushstrokes. Then sequentially write the characters for "wind, cloud, rain, thunder, lightning, dragon, fog, command," each requiring additional brushwork. Next write the "heart seal" (xinyin, a special talismanic imprint) without additional strokes, followed by the "auxiliary seal" (zuoyin) written below, also without strokes. The reverse side should bear the characters for "swift, charge, penetrate" without additional strokes. After completion, the talisman must be consecrated by summoning celestial generals in the air before burning, using one to three sheets of paper.

Special mention is made of three dragon talismans required for rain rituals: one placed in a water vat, one attached to a petition for the dragon deities, and one burned in a water bowl exposed to sunlight. Additional talismans may be burned near rivers or stirred in water vessels. Talismans can be written with black ink on blue paper, cinnabar on red paper, or even inscribed on brick tablets placed in spiritually potent locations.

When issuing petitions, after completing the main talisman, yellow paper must be used to write the "portal designation" (qiaohao) with the corresponding time period noted. Different rituals—whether summoning rain, clearing skies, or snow—require specific stacking sequences: rain rituals follow "wind, cloud, thunder, rain, lightning, dragon, fog, command, heart seal"; clear sky rituals use "wind, clear, heart seal, auxiliary seal"; snow rituals employ "wind, cloud, rain, fog, snow, heart, auxiliary."

Paper colors carry significance: first yellow, then white, red, black, and finally blue. Petitions use one to three sheets—red paper with black ink bearing the inscription "Your subject [name] respectfully seals," bound with five-colored silk threads. Urgent petitions must be burned with Chinese honey locust pods, dalbergia incense, and bamboo leaves. Alternatively, two bamboo slats may be used—one for the talisman, another for celestial generals' names—tied together with thread before burning.

The text emphasizes that ritual efficacy fundamentally depends on the practitioner's spiritual state. As the patriarchs taught: "The magic's power requires my spirit's power"—where "spirit" (shen) refers to one's own mind. When the mind remains clear and pure, with every action aligned with the Dao (the Way), communion with the divine occurs naturally. Celestial generals have no fixed form—they manifest entirely through the cultivator's spiritual resonance.

This scripture primarily elucidates the concrete methods of Daoist cultivation and deity invocation, divided into several key sections:

The text first explains the fundamental principle of cultivation: when one's inner mind resonates with the divine, one naturally attunes to the Thunder Department deities (celestial generals governing thunder and lightning in Daoism) without relying on external techniques like breath regulation. The crux lies in the natural fusion of one's being with the Five Qi (the energies of Metal, Wood, Water, Fire, and Earth from the Five Phases), whereby the Hundred Spirits will spontaneously gather. It emphasizes the core concept that "all methods are ultimately methods of the heart," illustrating how all Daoist practices are fundamentally rooted in mind cultivation.

The text then details ritual procedures: Practitioners must first calm their minds and concentrate their Shen (spirit) by teeth-clicking, then purify the altar by burning cleansing talismans (Fulu). Silently recite incantations to purify heaven and earth before offering incense to convey one's intentions. Through chanting specific mantras like the "Chapter of Mysterious Communion" and "Chapter of Sacred Entry," one visualizes incense smoke permeating the space and ancestral masters manifesting within luminous halos—at which point reverent bows should be made while silently praying or presenting memorial petitions. Subsequently, invocation talismans are burned while summoning chants are recited to beckon deities.

Two crucial incantations are recorded:

1. The "Decree Command": Invoking the authority of the Celestial Worthy of Primordial Beginning (Yuanshi Tianzun, the supreme Daoist deity) to command celestial generals to swiftly descend and subdue demonic forces, possessing formidable power.

2. The "Secret Summoning Mantra": An esoteric chant composed of special syllables requiring seven consecutive recitations.

Regarding verification methods for memorial petitions: If after the ritual one experiences mental clarity and harmonious Qi flow, it signifies successful celestial communication; if experiencing dullness, one must return to seated meditation and chanting until achieving physical-mental equilibrium.

Finally, the text explains rain-summoning methods: During severe droughts, practitioners enter quiet chambers for seated meditation, reaching a state of self-object unity. Upon perceiving the Thunder Emperor (the sovereign deity of the Thunder Department) in meditative absorption, they immediately burn rain-invoking talismans while specifying fulfillment times (e.g., noon the following day). If unanswered, the ritual may be repeated during the Wei hour (1-3 PM).

These contents demonstrate the mystical practice system of Daoism that integrates inner cultivation with external rituals to commune with deities and regulate natural phenomena.

This passage explains the specific methods and precautions for Daoist rainmaking, sunshine-praying, and thunder-summoning rituals. Regarding time-bound talismans (fulu), if the desired effect isn't achieved within the designated period, one may issue a second or third talisman consecutively, but should adapt flexibly to circumstances rather than rigidly following procedures.

After completing rainmaking rituals, practitioners should set aside talismanic documents (fuzhang) and scriptural incantations (jingdao), then enter a quiet chamber for meditation. One may maintain pure silence, focus on Dao cultivation (shoudao), or recite scriptures, but must avoid obsessing over when the magic will take effect—such attachment will backfire. Daoist methods emphasize wuwei (non-action) and naturalness; the more one lets go of expectations, the more effective the results. Forced outcomes become mere illusions.

During meditation, reach the state where both self and external objects are forgotten. At this stage, one might observe flowing clouds or shifting winds before their eyes, or experience physical signs like ear warmth, visual dizziness, or stomach rumbling—all indications of spiritual resonance. Profuse sweating corresponds to heavy rain, light sweating to drizzle, while no reaction means no effect. The key is maintaining a natural state of "seeming to see yet not seeing, seeming to hear yet not hearing."

Sunshine-praying follows similar principles. During meditation, witnessing radiant light like a sun disk illuminating all directions, or observing dispersing clouds and rosy skies, signals efficacy. For thunder-summoning, one may feel wind and thunder vibrations, bodily heat, or joint crackling in deep stillness.

The Qingwei lineage (an important Daoist school) typically achieves prayer results without altar ceremonies through natural resonance. If using an altar, simply complete the petition, have participants chant the Wooden Youth Mantra or scriptures while circumambulating the altar, then enter meditation. When the moment arrives, immediately rise to "fly the talisman" (feifu) and summon celestial generals to hasten thunderstorms.

For disaster-averting prayers to the Dipper (rangzai gaodou): The Northern Dipper is called "Heaven's Throat and Tongue," rotating at the celestial pivot to govern creation. Scriptures describe it as "vast enough to encompass all realms, subtle enough to enter dust particles"—omnipresent. Thus, Dipper prayers yield exceptional efficacy.

Though methods of Petitioning the Dipper (appealing to the Northern Dipper deities) vary, the sincere devotion behind them remains the same. With genuine piety, even ordinary people can make offerings with simple flowers and clear water to conduct their own petitions—how much more so for Daoist practitioners? The various categorized methods—employing specific divine generals or particular rituals—ultimately rely on these celestial envoys as intermediaries. The efficacy of the petition depends wholly on our sincerity. Understanding this principle, one realizes that even without divine generals, rituals, lamps, or incense, one can still appeal to Heaven. The ancients established lamp altars and ritual images as external forms, with the secondary purpose of using lamp flames for divination. If ordinary people can predict the next day's fortune by observing nighttime lamps, how much more can be revealed when making petitions before the deities? As the Patriarch taught: "When a thousand households petition the Dipper, all observe the same lamp signs." This saying holds profound truth.

When practicing Daoist methods, one should first calm the mind and stabilize the Shen (spirit) before lighting the ritual lamps. Gazing upon the Dipper lamps, visualize the Northern Dipper's radiance shining before you. Then offer incense to express your intention, sit quietly to concentrate the spirit, and begin the petition when sudden inspiration arises. This is using the Heavenly Heart to resonate with celestial will—after which observing the lamp signs will naturally yield spiritual responses. This principle is difficult for the unenlightened to comprehend. As for submitting memorials, chanting praises, or constructing ritual altars—these are all matters of liturgical protocol (Keyi).

For healing methods: minor ailments require only one, two, or three Qi-character talismans for immediate effect. If ineffective, petition with Fulu (talismans), dispatch divine generals to expel pathogenic influences, and finally seal with talismanic compresses—there are no restrictions on methods. For serious illnesses caused by evil Qi, petition with Dongzhang scriptures; for malicious hauntings, use demon-subduing scriptures. All illnesses, whether major or minor, should combine talismanic ingestion without rigid adherence to form, nor constant concern about efficacy—such preoccupations would create new attachments. The Qingwei Daoist method emphasizes natural spontaneity, hence its marvelous efficacy. Thus the Patriarch taught: "Don't ask if it works, don't question its proof—draw talismans effortlessly, without a single thought." The master said: "When my mouth speaks, it becomes imperial decree—never doubt this." After performing rituals, what's said is said—why entertain further doubts? Once doubt arises, sincerity diminishes, making spiritual response impossible. The Patriarch instructed: "The heart must comprehend meaning, every thought must be true—this very mind is the Dao." In daily life, maintain proper mindfulness and nurture authentic nature—then a spark of spiritual light will naturally abide perpetually.

This scripture elucidates the core principles of Daoist cultivation and the methods of refining and liberating souls (salvation rituals for the deceased).

Regarding the luminous state: When practice reaches perfection, a harmonious, translucent radiance manifests within the body, illuminating heaven and earth. In the Hall of Light (upper Dantian) and the Jade Capital (the central chamber of the brain), inner and outer clarity become perfectly transparent. In stillness, one remains unmoved like a mountain, yet when activated, its wondrous functions are limitless—able to perceive fortune, misfortune, and omens as clearly as reading lines on one’s palm, naturally sensing without deliberate inquiry.

The liturgical traditions of the Qingwei lineage (an important Daoist school) originate from the Daoist Lord of Jade Radiance (a revered deity) and have been transmitted through standardized rituals. The key to practice lies in focused inner contemplation (neiguan meditation). The patriarchs teach that in the Jade Dawn purification rites (a type of Zhaijiao ritual), petitions ascend to the Three Pure Realms (Jade Clarity, Upper Clarity, and Supreme Clarity—the three celestial realms), clear as the moon in the void, where celestial golden texts (sacred scriptures) naturally manifest their responses.

Concerning salvation methods: While worldly salvation techniques are numerous—some specializing in water methods, others in fire methods, with debates over their sequence—these attachments to external forms miss the essence. True salvation refines the yin-substance of departed souls with one’s own true yang (primordial yang energy), independent of external water or fire. The patriarchs clarify: The ascent of a single spark of spiritual light from the Dantian (lower energy sea) to the Muddy Pellet Palace (upper Dantian) is the key to liberation. When Kan and Li (the water and fire trigrams) invert, they form the Seven Treasures; when followed sequentially, they create a pit of fire. Only those who comprehend the Dao understand true salvation—using one’s yang strength to elevate the yin of the deceased, and one’s wisdom to awaken the deluded. To attempt saving others before attaining liberation oneself is mere delusion.

Essential teachings: The supreme Dao is profoundly simple, consistent from beginning to end. Rituals and talismans are merely expedient means for teaching. During salvation, recite the "Middle Chapter" (from the Scripture of Salvation), visualizing spiritual light rising from the Dantian through the crown to merge with the Wuji (cosmic origin). Avoid fixation—the slightest deviation creates obstructions.

Practical method: Choose an auspicious day and time for seated meditation. Harmonize the breath, sit upright with eyes closed, and focus the mind on the Central Palace (middle Dantian). Upon entering the meditative state where self and objects are forgotten, gradually circulate golden light from the eyes to unite with the void.

This scripture elucidates the essential techniques of Daoist cultivation and ritual practice. It begins by describing the meditative practice of visualizing golden light filling heaven and earth, imagining oneself dwelling within Taixu (the cosmic origin), surrounded by myriad deities awaiting commands. Practitioners must maintain this state persistently, as prolonged practice leads to the attainment of the "emerging from being and entering non-being" realm, achieving union with the Dao. The verse reminds cultivators to focus on emptiness, avoiding scattered thoughts, thereby revealing the innate radiance of one's true nature.

The text then recounts an oral instruction transmitted by Perfected Lord Baoyi of Yunshan to Perfected Lord Hunyin of Meishan: externally, one must avoid excessive exertion that depletes Jing (essence), Qi (vital energy), and Shen (spirit); internally, one must maintain serene Wuwei (non-action), merging with the Dao. Only by preserving equanimity can the internal union of Yin-Yang generate the power of thunder. It further explains how humanity's innate spiritual spark becomes obscured by postnatal physical form, and only through relinquishing attachments can original clarity be restored.

Regarding the secret method of summoning divine generals: first, the mind must become still as water, visualizing golden light arising from intention while sensing the Qi of emptiness entering formlessness. When divine radiance emanates from both eyes to permeate the void, thunder deities may be summoned to descend from heaven and emerge from earth—these towering celestial warriors, resplendent in majestic power, stand ready to obey commands. Yet the scripture emphasizes that true efficacy lies in spontaneous resonance, not forced visualization.

Finally, it reveals the essence of Fulu (talismans and registers): their fundamental principle is "union" and "faithful correspondence." Through the practitioner's spirit harmonizing with celestial deities, formless divine Qi imbues physical talismans with efficacy. When drawing talismans, one must resonate one's own Shen (spirit) with the invoked deity's spirit, and synchronize one's Qi with their Qi—only thus created talismans manifest authentic potency.

This scripture reveals the core principles of Daoist talisman (Fulu) inscription. True talismanic power does not lie in superficial brush techniques, but in the practitioner's inner spiritual state and resonance with the cosmic Qi (vital energy).

The foundation of talisman creation rests upon mobilizing the Primordial Qi (the universe's fundamental energy). As transmitted by ancestral masters, the method involves: visualizing celestial script patterns with the eyes while comprehending thunder mysteries with the heart. No forced imagination or striving is needed—when the mind becomes perfectly clear, spiritual efficacy arises naturally. Talismans work because they align with the Dao; their power requires no deliberate pursuit of causes. Regrettably, many contemporary practitioners fail to grasp that "Wuwei (non-action) constitutes true skill, and naturalness represents the supreme path," obsessing instead over superficial techniques of brushwork and arcane methods.

The genuine secret lies in: first purifying the heart-mind to eliminate distractions, allowing consciousness to connect with all directions until the Original Spirit (Shen, innate spirituality) manifests. When holding the brush, focus the gaze intently on its tip, visualizing divine light radiating from both eyes to converge between the eyebrows as a millet-sized luminous pearl. This golden light then flows into the brush hairs. During inscription, practice "the brush following the eyes' movement," silently reciting thunder department mantras while envisioning golden radiance filling heaven and earth. Though specific operations follow each lineage's esoteric formulas, the crucial element remains the practitioner's inner cultivation—that spark of Primordial Light is fundamental. Those truly mastering talismanic arts cultivate skill beyond cinnabar and ink.

The subsequently listed "Mysterious Primordial Nurturing Spirit's Dao Marvel" represents alternate names for this talismanic system, presided over by Immortal Lady Han Xiuyuan and two Thunder Kings governing celestial and terrestrial thunder. The talismans divide into "active" and "quiescent" applications: active talismans serve dynamic rituals like summoning clouds/rain or healing/exorcism; quiescent talismans address static needs such as calming storms or stabilizing earth/water.

(Note: The mentioned "Three-Five Taboo Characters" refer to secret thunder method incantations, "millet pearl" denotes the luminous point appearing between eyebrows during Neidan (internal alchemy) practice, and "golden serpent" metaphorically represents energy flowing through talismanic script.)

This scripture primarily elucidates the Daoist principles governing the interplay of movement and stillness (Yin-Yang) in cultivation and ritual practice. Its core teaching reveals that extreme stillness transforms into movement (employed in urgent rituals like rainmaking), while extreme movement returns to stillness (used in rituals for clearing skies). Movement and stillness mutually depend on and transform into each other, much like thunder's inhalation and exhalation. Masters explain that stillness conceals movement, and movement contains stillness—this represents the wondrous function of Yin-Yang pushed to its limits, where things reverse upon reaching extremes, a fundamental law of nature. When major prayer rituals prove ineffective, this profound principle of Yin-Yang mutual adjustment can be employed to harmonize cosmic creation.

Master Shao Yong (a renowned Northern Song Neo-Confucian philosopher) once said: "The mystery between movement and stillness constitutes the most subtle essence of Heaven, Earth, and humanity." Daoist practitioners should deeply contemplate this truth.

The text then details practical ritual techniques: During cultivation, maintain a mental state as perfectly integrated as primordial chaos, before directional concepts formed. When the inner luminous point (the focal point of meditation) manifests, it illuminates and penetrates the Three Realms (heaven, earth, and humanity), causing even malevolent spirits to retreat—this is called the "Heavenly Root" (life's primordial source). Through specific directional alignments (the intersecting points of the four cardinal directions: Yin, Shen, Si, Hai) and hand techniques, one can distinguish Yin-Yang and summon thunder. When celestial mechanisms remain obscure, divine power must be activated covertly.

Different rituals produce distinct effects: Thunder disperses stagnant energies, clear skies require Yin-Yang harmonization, while wind, snow, and lightning each have specific applications. When performing the "Thunderclap Subjugation" method, heaven and earth change colors, and all evil entities are annihilated. Practitioners must maintain external unblinking focus and internal clarity (sustained concentration) for unimpeded spiritual efficacy.

Finally, it outlines essential cultivation techniques for water-fire alchemy (six methods each), seasonal Yin-Yang harmonization patterns, and directional gate functions: For instance, the "Human Gate" stabilizes dwellings and heals illnesses; the "Dui Position" governs warfare and cloud formation; the "Heavenly Gate" facilitates celestial communication; the "Li Position" controls clear skies and lightning; the "Kan Position" regulates rain and snow; the "Earth Portal" summons winds; the "Zhen Position" commands thunder; and the "Ghost Path" exorcises spirits and liberates souls. All must be applied according to the Five Phases' generative and controlling relationships.

This scripture primarily discusses two aspects: the methods and mental techniques for drawing talismans (fulu), and the responsibilities of practitioners during natural disasters.

When drawing a talisman for petitions to the Qian position (northwest direction), one should begin the brushstroke from the Qian position, drawing circular light patterns to the left before returning to Qian to complete the stroke. The incantation is then written in the center, incorporating key esoteric components such as the "tiger" or "thunder" glyphs, before finally concluding at the Qian position. The master teaches that when drawing talismans, one must achieve "circles within circles, strokes within strokes, and mysteries within mysteries" — all intuitively grasped through mental cultivation and perfected through skillful technique. Only thus can the profound mystery of the Dao be manifested. Mere mechanical imitation without understanding the underlying principles would be no different than drawing gourds by copying their outline.

The second part explains that celestial anomalies and natural disasters — such as eclipses, climatic disturbances, droughts, plagues, warfare, or rampant banditry — arise when collective karmic retribution accumulates and provokes celestial wrath. These may stem from oppressive governance, judicial corruption, or moral degeneration among the populace. When encountering such circumstances, practitioners should observe purification fasts (zhaijiao), bathe ritually, purify their spirit (shen), sever worldly engagements, and sincerely petition the Celestial Emperor, willingly taking upon themselves the people's transgressions. With sufficient sincerity, one may move heaven to avert calamity. Subsequently, performing the prescribed talismanic rituals will assuredly produce effects.

Xiong Daohui, a lineage holder of the Qingwei tradition from Western Mountain, particularly admonishes fellow disciples: "What matters is not eloquent speech but concrete practice." Whether praying for clear skies or rain, one must first silently recite petitions, draw talismans to summon celestial generals, and set a designated timeframe. Then, through fasting and ritual bathing, enter the meditation chamber to eliminate distractions, unifying body and mind with emptiness. Within this primordial chaos (hundun), visualize a point of sunlight gradually expanding until it illuminates heaven and earth like a solar disc — internally and externally radiant, with all sounds silenced. Maintain this state for a full day or night, only leaving the chamber when the weather clears (or rain falls).

This scripture primarily elucidates the concrete methods of Daoist cultivation and ritual practice, along with the philosophical connotations of the "primordial chaos" concept.

Key points regarding cultivation and ritual practice:

During cultivation, one must concentrate the spirit (Shen) and allow the primordial Qi to ascend, visualizing scenes where mountain and marsh energies intermingle, thunder and lightning clash, heaven and earth darken, and torrential rains pour down. This state should be maintained for several hours or even throughout the night, continuing until spiritual resonance manifests. When healing illnesses, the ritual master must calm the mind with focused intent, using the brush to inscribe talismans (Fulu) while concentrating their luminous spirit (Shen) and righteous Qi within the talisman to expel pathogenic energies from the patient. For yang-afflicted conditions, water strokes are added to the talisman; for yin-afflicted conditions, fire strokes are incorporated. During exorcisms, one must visualize the Thunder Gods unleashing their might, brandishing weapons to capture malevolent entities at the patient's residence, continuing until complete eradication is achieved.

When inscribing talismans, maintain single-minded concentration, visualizing the ancestral masters above and divine generals before you, wielding the brush with the purity of the Celestial Sovereign. Talismans should be written with ethereal clarity, incorporating specific techniques according to circumstances without disorder. Those who truly attain the Dao (Dao) maintain daily conduct as if facing deities with perfect sincerity—thus all spirits naturally come to their aid, and their bodies remain in health. Understanding this principle naturally rectifies one's thoughts, eliminating the need for forced stillness.

Philosophical interpretation of "primordial chaos":

Primordial chaos embodies the fundamental substance of the Great Dao (Dao), encompassing all existence. It represents pure yang nature, possessing the four virtues of origination, prosperity, advantage, and steadfastness. When activated, it commands myriad spirits; when withdrawn, it contains the three realms. From the Daoist perspective, it manifests as the light, clear Qi ascending to form heaven; in trigram symbolism it corresponds to pure Qian (Heaven), representing supreme yang; in transformation it demonstrates yang generating yin, containing infinite permutations.

The image of primordial chaos is boundless—formless, shapeless, and eternally present. It also embodies ultimate yin substance, possessing the all-encompassing virtue (De) of Kun (Earth). Whether summoning rain, healing illnesses, pacifying landscapes, channeling springs, or invoking dragons to transport water—all applications follow this principle. Viewed through the Dao, this represents the condensed state of heavy, turbid Qi.

This passage uses the principles of Yin-Yang and the Five Phases (Wood, Fire, Earth, Metal, Water) along with trigram symbolism to explain the patterns of cosmic transformation. In terms of spatial orientation, the lower position represents the earth, which in Yi (Change) philosophy symbolizes the mother and feminine principle, corresponding to the Kun (Earth) trigram—the archetype of mature Yin. When Yin energy reaches its extreme, it transforms into Yang, demonstrating the fundamental law of Yin-Yang alternation.

At the zenith of Yang energy, Yin is born—thus within pure Yang (Lao Yang) emerges nascent Yin (Shao Yin). This transformation principle can be applied in rituals to clear rainy weather, as excessive Yang creates overwhelming Fire energy that requires tempering. The mythological golden crow (three-legged raven in the sun) and the hollow center of the Li (Fire) trigram both illustrate this truth of "Yang giving birth to Yin."

Conversely, at the peak of Yin energy, Yang is generated—within pure Yin (Lao Yin) arises nascent Yang (Shao Yang). This principle governs rain-summoning rituals and cloud manipulation, as excessive Yin leads to flooding Water energy needing regulation. The legendary jade rabbit in the moon and the solid center of the Kan (Water) trigram exemplify this "Yin generating Yang" dynamic.

During Yang's intermediate developmental phase, it divides into both Shao Yin and Shao Yang energies. With Shao Yin above and Shao Yang below, this configuration suits weather-clearing rituals—analogous to spring's dominant Wood energy requiring Fire modulation, or the harmonious marital relationship mirrored in the Tai (Heaven-Earth) hexagram's symbol of cosmic intercourse.

When Yin progresses to its middle phase, it similarly produces both Shao Yang and Shao Yin energies. With Shao Yang above and Shao Yin below, this arrangement facilitates rain rituals—comparable to autumn's Metal dominance requiring Water adjustment, or the mother-child relationship reflected in the Pi (Heaven-Earth Disconnected) hexagram's symbol of Yin-Yang separation.

Even when Yang-generated Shao Yang and Shao Yin appear with Shao Yang above and Shao Yin below, the configuration remains suitable for clearing skies—as seen in summer's blazing Fire energy at Yang's apex. These transformations collectively manifest nature's rhythms of Yin-Yang waxing-waning and the Five Phases' mutual generation-restriction cycles.

This passage elucidates the Daoist principles of Yin-Yang (阴阳) energy transformation in spiritual cultivation, using seasonal cycles, trigram symbolism, and bodily practice as metaphors.

From the perspective of the Bagua (八卦) trigrams, the summer solstice corresponds to Gou Hexagram (Heaven above, Wind below), when Yang energy reaches its peak. At this time, male practitioners enter the cultivation space of female practitioners (the "female chamber"). When Yang energy is at its strongest, it undergoes transformation, dividing into Lesser Yang (newly emerging Yang) and Lesser Yin (newly emerging Yin). Here, Lesser Yin resides above, while Lesser Yang remains below. This state of Yin-Yang interaction can be used to invoke rain, as Daoist theory holds that water energy (Qi) is most potent during the Zi hour (midnight), precisely when Yin is at its zenith and Yang begins to stir.

Conversely, the winter solstice aligns with Fu Hexagram (Earth above, Thunder below), marking the peak of Yin energy. Here, female practitioners enter the cultivation space of male practitioners (the "male chamber"). When Yin is dominant, it also divides into Lesser Yang and Lesser Yin, with Yin energy positioned above. This configuration is employed in rituals to summon clear skies.

When the most potent Yang (Greater Yang) and the most potent Yin (Greater Yin) fully merge, they generate new Lesser Yang energy. This mirrors the Neidan (内丹) process where human nature (Xing, 性) gives rise to the primordial spirit (Shen, 神), which in turn produces prenatal Qi (炁). In the metaphor of conjugal union, it resembles a husband and wife conceiving a male child, corresponding to the Gen Hexagram (symbolizing the young male). From the perspective of trigram lines, Yang energy resides externally while Yin energy remains internal, yet transformation still occurs.

These principles find practical application in Daoist cultivation and ritual arts. For instance, rainmaking and sun-summoning ceremonies must align with these cyclical patterns of Yin-Yang transformation in both timing and method.
