《道法會元》Vol. 98

This scripture documents a rain-praying ritual system known as the "Great Method of Azure Pool Thunder Supplications from the Nine Heavens," primarily describing the iconography and functions of the deities involved in the ceremony.

The principal deities comprise four supreme beings: the Most High Lord of Primordial Commencement of Floating Li (Daoism's supreme deity), the Jade Emperor of Vast Heaven (ruler of the celestial court), the Empress of Earth (deity of the land), along with the Great Emperor of Thunder Ancestry and the Universal Transformation Thunder Sovereign of Responsive Origin from the Nine Heavens (both supreme thunder deities in the Thunder Department).

The text then details the distinctive iconography of key thunder generals:

General Tao Sheng (Great Deity of Flying Fire Command over Thunder) appears formidable: with fleshy horns, crimson hair and azure visage, his crane-beak-like eyes set in a cyan body featuring four wings and dragon claws. His left hand forms a thunder mudra while his right wields a sword, clad in red skirts tied with an immortal's sash.

General Deng Bowen (Great Deity of Swift Fire Thunder Ordinances) shares similar features: three eyes resembling an eagle's beak, dragon-clawed wings, holding a thunder anvil in his left hand while raising a thunder hammer in striking posture with his right.

Judge Xin Fengcheng (Thunder Department's Fierce Official) wears an ox-eared official hat, his azure face sporting silver teeth, robed in green with a waist sash. He holds the Thunder Department's register in his left hand and a fire-writing brush for records in his right.

Messenger Zhang Jue (Swift Thunder Envoy) resembles the previous two but carries a black command banner and giant axe. When summoning thunder, he waves the banner; returning to the altar, he sheathes it at his waist to wield the axe with both hands, leading countless thunder deities surging like storm clouds. For document delivery, he dons red robes with green boots, holding a memorial in his left hand while clearing the path with his axe.

The entire Thunder Department hosts numerous deities, all sharing characteristics like fleshy horns, eagle beaks, golden eyes, dual wings, and dragon-clawed limbs. During rain prayers they manifest dark dharma forms commanding water creatures (leopards, apes, earthworms etc.) to spray rainfall; for clear weather they assume crimson forms to halt rain and bring sunshine.

These deity images blend animalistic traits with ritual implements, embodying the Thunder Method tradition's principle of "manifesting power through form." The concrete divine imagery vividly expresses thunder's awe-inspiring might within Daoist thunder ritual systems.

This scripture describes the imagery, functional divisions, and cultivation methods of various thunder deities and their retinues within Daoist thunder ritual systems, as well as how practitioners can attune themselves to cosmic energies through specific techniques.

Regarding thunder deity retinues: The celestial river contains fire-breathing beasts (tigers, boars, monkeys, snakes, etc.) moving in formations. When performing snow-invocation rituals, they appear with white faces and bodies, called the "White Brahma" group. Water-driving beasts (leopards, wildcats, apes, earthworms, etc.) move in groups exhaling snow. The dragon-thunder deities have human heads with dragon-scaled bodies, featuring wings and claws, known as the "Southwestern Abyss Flowing Light Lords." The water-thunder deities possess human heads with tortoise bodies, called "Southeastern Abyss Jade Thunder Pure Masters." The earth-thunder deities appear with demonic faces and iron armor. Northern water-thunder messengers have black faces and hair, standing on water wheels, while southern fire-thunder messengers have crimson faces and red hair, standing on fire wheels—each accompanied by countless water or fire creatures. There are also deities representing the twenty-four solar terms and seventy-two city gods symbolizing seasonal micro-climates.

Regarding cultivation timing: Special emphasis is placed on observing lunar phases (first crescent on the third day, waning moon on the eighteenth, first and last quarter moons, etc.). These celestial phenomena correspond with tidal movements and serve as crucial temporal nodes for both thunder rituals and Neidan (internal alchemy) practice.

Specific cultivation methods: Practitioners must sit in stillness while reciting the Golden Light Incantation, visualizing their bodies as withered trees consumed by heart-fire, with Xun-wind (southeastern breeze) scattering the ashes to leave only pure white Qi. In this state of primordial chaos, they maintain an unextinguished spark of spiritual light that eventually coalesces into an infant form (symbolizing the internal elixir), seated cross-legged with hands in the "embryonic grasp" mudra. The practice requires internal freedom from random thoughts and external detachment from sensory objects, entering a twilight state between wakefulness and sleep known as the "Central Mountain Spirit"—referring to the meditative state where consciousness abides at the center.

This scripture describes the concrete practice of Daoist Thunder Magic (a ritual art for summoning thunder deities and performing thunder rites). The practitioner must visualize transforming into the Celestial Worthy of Universal Transformation by Thunder's Voice (supreme thunder deity in Daoist cosmology), invoking thunder gods through specific incantations and meditation techniques.

First, the practitioner focuses intention, imagining their transformation into the Celestial Worthy. At this moment, the sun and moon merge above the crown of the head, descending through the skull to settle in the Dantian (the "jade pool" energy center). Simultaneously, the Big Dipper enters through the crown, its stars aligning along the heart meridian down to the kidney region. The entire body becomes enveloped in Gangqi (sacred protective energy) while myriad deities stand in solemn attendance.

Next comes the recitation of the Hundred-Word Incantation to activate the Primordial Ancestral Qi (primal cosmic energy) and summon thunder deities by their sacred names. The Big Dipper then inverts, opening the Celestial Gate at the crown, allowing all energies to surge upward toward the Milky Way. Beside the sixth star of the Southern Dipper appears a golden star the size of a chariot wheel—its radiance compels all thunder deities to pay homage. When this golden light merges with the thunder gods, it coalesces into a radiant sphere as the deities emit mighty roars.

At this climax, the Celestial Worthy (the practitioner's visualized self) chants the Hundred-Word Incantation while forming the Double Thunder Mudra (ritual hand gesture), drawing down the Celestial Gang's lethal energy (a specialized cosmic force). With a sudden thunderclap, the golden light explodes to reveal the true forms of thunder deities, arranged like dragons guarding pearls. After completing the ritual, the thunder gods transform back into golden light, entering through the nostrils to descend into the Dantian, followed by the Big Dipper's stars.

Key incantations include:

1. The Celestial Treasure Mantra: Used when the Celestial Worthy of Primordial Beginning (highest Daoist deity) suspended the jewel to expound scriptures, containing all cosmic truths.

2. The Central Mountain Divine Spell: Composed of sacred syllables "Om, Mo, Ni, Li, Hei, Chi, Xu, Wu"—when chanted as incantations or written as Jade Script of Primordial Beginning (divine characters).

3. The Thunder God Summoning Spell: Invoking the authority of the Nine Elders Immortal Officials to command thunder gods from five directions to attend the ritual altar immediately, with threats of divine punishment for disobedience. The subsequent series of esoteric syllables constitute secret mantras for summoning different thunder deities.

These practices require repeated training in the "release and retrieval" cycle—projecting energy outward then drawing it back inward. The entire ritual integrates visualization, incantation, mudras, and other essential elements of Daoist magical arts.

This passage is a ritual incantation and operational guide from Daoist Thunder Magic (a practice for summoning lightning powers), consisting primarily of three sections:

The first part contains emergency invocations to deities. The phrase "急急召汝名天下速至速至" (Jí jí zhào rǔ míng tiānxià sù zhì sù zhì) means urgently calling upon a deity's name and commanding their immediate manifestation. The concluding formula "急急如律令" (Jí jí rú lǜlìng), commonly used in Daoist spells, signifies that the command must be executed as swiftly as legal decrees. The subsequent syllables like "唵吽吽" (Ōng hōng hōng) are esoteric mantras, each corresponding to specific deities or cosmic forces.

The second section records two complete Thunder Magic incantations: the "Hundred-Word Thunder Summoning Spell" and the "Hundred-Word Thunder Manipulation Spell." These spells combine Sanskrit transliterations with Daoist secret characters. For instance, "唵天皇伽耶霹雳摄" (Ōng Tiānhuáng qiéyē pīlì shè) invokes the Celestial Emperor (a high-ranking Daoist deity) to unleash lightning. Recurring syllables like "吽" (Hōng) and "唵" (Ōng) serve as key phonetic triggers for channeling cosmic energies, used in conjunction with mudras (ritual hand gestures) and fulu (Daoist talismanic writings).

The third part details directional protocols for ritual performance. Based on celestial stem-earthly branch combinations (the ancient calendrical system), practitioners must initiate rituals in specific orientations—for example, on "甲巳日" (Jiǎ-Sì days), starting from the Chen position (southeast-by-east) and concluding at the You position (due west). It also lists inauspicious star positions corresponding to midnight (Zi hour) and the 1-3 AM watch (Chou hour) during solar terms like Winter Solstice and Major Cold—for instance, during Winter Solstice's Zi hour, malignant stars occupy the Wu position (due south)—warning ritual masters to avoid or neutralize these directions.

These incantations and operational methods were practical thunder rituals used by Song Dynasty Daoist thunder masters. Through precise combinations of sacred syllables, spatial orientations, and temporal cycles, they achieved the summoning of thunder generals and the harnessing of natural forces. Elements of this Thunder Magic tradition continue in contemporary Daoist zhaijiao (purification rituals) and keyi (liturgical ceremonies).

This scripture details the operational procedures for four Daoist rituals: rain summoning, thunder invocation, snow petitioning, and clear weather supplication, focusing particularly on talismanic (fulu) designs and their corresponding temporal alignments.

Regarding temporal calculations: After the Autumn Equinox, the Zi hour (11pm-1am) corresponds to the Mao position (due east), while the Chou hour (1-3am) aligns with the Chen position (southeast). After Frost's Descent, Zi hour shifts to Chen position and Chou hour to Si position (south-southeast). After Minor Snow, Zi hour moves to Si position and Chou hour to Wu position (due south).

Talisman materials require specific preparation: yellow paper with black ink for rain summoning, yellow paper with red ink for thunder invocation, and black paper with white powder for snow petitioning. When drawing the talisman, first write the character "晅" (representing the Solar True Lord's incantation), followed by "朒" (Lunar True Lord's incantation). Lunar energy must harmonize with solar forces, using black ink to inscribe Sanskrit symbols. The central design features doubled Kan trigrams (☵, representing water) for rain, doubled Zhen trigrams (☳, thunder) for thunder invocation, and doubled Dui trigrams (☱, marsh) for snow.

Practical execution involves writing the character "雷" (thunder) within a "田" grid pattern, incorporating the character "玄" (mystery), then superimposing the hundred-character mantra "Heavenly Sovereign Gayā Thunderbolt Summons". Yin days require additional specific symbols, as do Yang days. Both the talisman's "wings" and base require similar treatment, concluding with five encircling strokes. Completion requires seated meditation (dazuo) and cultivation exercises, chanting situation-specific mantras.

Clear weather talismans demand red paper with cinnabar ink, beginning with the Lunar True Lord's "朒" character followed by the Solar "晅". Solar energy must synchronize with lunar forces, using red Sanskrit symbols. The center bears doubled Li trigrams (☲, fire), similarly framing "雷" within a "田" grid with "玄". The four "wings" must be drawn straight, flanked by "火" (fire) characters - two on each side, two at the base, and one atop the design. Finalization requires meditation while reciting fire mantras and Great Virtue incantations for weather clearing.

The concluding "entering the mystery" (ruxuan) technique involves incorporating water and fire constellation symbols at the four corners of the "雷" character's "田" grid for weather clearing. All operations require synchronization with specific cultivation techniques.

This scripture describes the complete ritual process and internal cultivation methods of Daoist rainmaking magic. At its core, the practitioner (fashi) achieves resonance with celestial bodies and thunder deities through visualization practice (cunxiang), mobilizing cosmic energies to alter weather patterns.

The text first introduces the "Dark Luminary" (anyao), a mysterious constellation in the southwestern Kun position resembling a yellow tiger holding a sword. This stellar formation governs all stars—on earth it devours metal, in water it subdues flood dragons, in heaven it regulates constellations. Even the Southern Dipper (Nandou), the stellar deity governing life and death, must submit before it.

When drawing talismans (fulu), special attention must be paid to brushwork structure: the talisman head, body, and feet each follow precise rules. The arm strokes resemble an anvil, the trailing strokes add wind ribbons, the two wings each contain six dots—completed in exactly five brushstrokes. After inking the talisman, the practitioner enters meditative stillness to infuse it with spiritual power (shen).

The cultivation method proceeds as follows: First, the practitioner enters a state of primordial chaos (hundun), visualizing themselves transforming into an infant form while silently reciting the Golden Light Incantation. Next, they imagine embodying the Supreme Thunder Emperor (Leizu Dadi), with a cloudless azure sky above, the sun and moon suspended to left and right. The Southern Dipper appears before them while the Northern Dipper manifests in the void. For rainmaking, they visualize the moon eclipsing the sun (yue he ri hei); for clearing skies, the reverse (ri he yue hong).

At this stage, all constellations dissolve into golden light (jinguang) which the practitioner's "Brahma body" (fanshen—an energy body formed through cultivation) gently draws into the "Jade Pool" (bitan, an alternate name for the dantian). The practitioner then visualizes the Northern Dipper's radiance pouring through their crown into the heart center. Heart fire descends while kidney water rises—these two energies merge in the dantian. Thunder Department deities guard as the "Primordial Qi" (zuqi, the innate vital energy) surges upward from the crown.

In the final phase, the practitioner recites the Hundred-Word Divine Incantation, forms thunder mudras (shouyin), and strikes toward southern black clouds. With a thunderclap, the Celestial River Envoy (Tianhe shizhe) emerges leading countless thunder deities astride dragons, driving divine beasts to churn the Milky Way's waters into a torrential downpour. The entire ritual—combining internal cultivation with external magic—achieves the world-transforming effect described as "overturning the Dipper's handle to darken heaven, inverting the Silver River's snowy waves to fly."

This scripture describes a Daoist thunder ritual method that combines internal cultivation (Neilian) with external application. It establishes correspondences between the human body and the natural cosmos, where practitioners visualize and activate the "thunder deities" (manifestations of genuine Qi within the body) through meditation, then channel them through talismans and incantations for ritual efficacy.

During practice, internal energies reverse their flow like rivers running backward. The "Thunder Deity in the Water Depths" (referring to kidney essence/Jing) generates true fire (the gate of life's flame), which ascends from the coccyx (Weilü) to the Niwan Palace (upper Dantian) at the crown of the head. At this moment, the practitioner's spirit-Qi (primordial Qi, here called the "Thunder Ancestor") becomes infused into the ritual talismans.

For weather-clearing rituals, the Great Taoist Deity (a principal thunder divinity) leads thunder deities riding fire dragons and driving flaming beasts to scorch the heavens. Through Sanskrit-derived mantras, celestial waters like the Milky River and Yellow River are sealed, filling the cosmos with flames until the sun dominates the sky.

The text meticulously maps cosmic correspondences within the body:

• The crown corresponds to Mount Kunlun, with the brain's summit as the celestial river housing heavenly thunder deities
• The mouth contains the Jade Pool and Flower Pool, with saliva termed Jade Nectar and Sweet Spring
• The throat serves as the channel connecting celestial and earthly waters
• The navel's Qi Sea mirrors the Yellow River, home to dragon thunder deities
• The kidneys form the Water Palace representing rivers, dwelling place of water thunder deities
• The lower abdomen to coccyx corresponds to river deltas, inhabited by local thunder deities
• The gallbladder becomes the Central Pool, while the brow's Hall of Light gathers spring currents
• The Central Yellow Cavity (Huangting) forms the Emerald Deep, the sacred meeting place of all deities

The text concludes with instructions for summoning specific thunder deities (like Marshal Deng): The talisman begins with a solar incantation writing the character "晅" (xuān), includes the name "Deng," and features repeating patterns at designated positions. This exemplifies the characteristic "Qi-infused talismanic writing" practice of Daoist ritual traditions.

This passage describes the specific procedures and incantations for drawing fulu (talismanic symbols used in Daoist ritual practices) within the Thunder Rites tradition of Daoism. It focuses on the methods for summoning various Thunder Department deities (such as Marshal Xin, Marshal Zhang, Marshal Tao, and other thunder gods).

When drawing the talisman, one must first transform the Zhen trigram (one of the Eight Trigrams representing thunder) into the character "雷" (thunder), then execute five brushstrokes toward five directions while reciting the incantation "Thunder God of [direction], arise swiftly!" At the center of the talisman, the seven characters "天皇伽耶霹雳摄" (Tiānhuáng jiāyé pīlì shè) are written in overlapping strokes, smudged, then supplemented with four special sigils (represented in the original text with boxes indicating obscure ancient characters), accompanied by recitation of a hundred-word incantation during smudging.

Subsequently, one must add the three characters "阳日阴日" (yang day yin day) or "阴阳日" (yin-yang day), visualizing the infusion of divine power into the talisman through meditation. At the lower section, the character "雷" is written while reciting the "Thunder Summoning Incantation" to complete the process. Variations exist for different thunder marshals: for Marshal Xin's talisman, one recites the "Moon Lord Incantation" and writes the character "朒" at the top; Marshal Zhang's requires the "Heavenly Stem Incantation" with the character "炓"; Marshal Tao's talisman concludes with adding the character "火" (fire) while chanting the "Great Dignity and Virtue Incantation."

The final section on the "Eight-Character Petition Method for Supplication" explains how to augment specific trigrams with designated characters (such as adding "丁" to the Qian trigram) to determine the talisman's purpose. The application varies according to the trigrams activated by ritual footsteps, and requires inscribing the names of emissaries from the Five Directions. These operations must align with specific temporal nodes (zi, wu, mao hours, etc.).

These talismanic practices belong to the esoteric transmission within Daoist Thunder Rites (a ritual system for commanding thunder and lightning). Each character and procedural step carries specific cosmological significance, serving as mediums for Daoist priests to communicate with the Thunder Department deities during ritual practice.

This passage explains the Daoist ritual procedures for summoning the Five Sacred Mountains' deities (the divine peaks of East, South, West, North and Center) and commanding the Ding-Jia guardian spirits (Daoist protector generals):

First, arrange the ritual formation according to the day's earthly branch orientation, gathering Sha Qi (malignant energy) and Tiangang Zhengqi (the righteous energy of the Big Dipper) to activate the ritual's potency. Inscribe the names of the Five Sacred Mountain deities at specific cardinal points: Mount Tai of the East at the Mao position (true east), Mount Heng of the South at Wu position (true south), Mount Hua of the West at You position (true west), Mount Heng of the North at Zi position (true north), while Mount Song of the Center spans across the Chen, Xu, Chou and Wei positions. Additionally, write the name of Yangzhou's local earth god at the Wu position, and inscribe the seasonal deity governing that month at its corresponding earthly branch location.

Commanding the Ding-Jia spirits involves two approaches: During seasonal nodes, trace the "Ding" days sequentially to identify six corresponding generals (e.g., the Xidannu General named Zou Bin for Ding-You days, the Duodannu General named Feng Ping for Ding-Chou days). During Qi cycles, trace the "Jia" days inversely to identify another six generals (e.g., the Jiediheli Goddess named Ye Changzhi for Jia-Yin days, the Jiepoheli Goddess named Jiang Hui for Jia-Shen days).

Different ritual purposes require specific talisman colors: yellow paper with black ink for rain prayers, red paper with cinnabar for clear weather, black paper with white ink for snowfall. The ritual must be performed in an incense-purified chamber, with deities' names written on talismans rolled into memorials. Each petition follows set formulas: rain rituals declare "breaking rivers to drive dragons bringing rain," clear weather rituals state "blocking rivers to recall dragons stopping rain," while snow rituals pronounce "breaking rivers to drive dragons bringing snow" - all concluding with invocations for the Three Realms' (heaven, earth and water) deities to bestow power.

Crucial warning: Both talisman-drawing and petition-submission require absolute secrecy. If witnessed by outsiders, the ritual loses efficacy, wasting all effort. These practices involve complex Daoist geomancy, divine hierarchies and talismanic traditions that demand strict adherence to prescribed liturgical protocols.

During the daily morning and evening incense offerings at the altar (the sacred space for Daoist rituals), focus your awareness on visualizing the Thunder Deity suspended in the void above your head. Imagine yourself as the Great Thunder Ancestor Emperor (supreme deity of the Thunder Ministry), guiding the fiery Qi (vital energy) within you to ascend while the watery Qi descends, allowing the interaction of Yin and Yang energies to coalesce into sacred Sanskrit mantras (empowered esoteric syllables). When you visualize the harmonious union of the sun and moon (a celestial phenomenon symbolizing perfect balance), a Sanskrit sigil will descend. At this moment, summon the corresponding sigil from within your body to merge with it. When the Thunder Deity above witnesses this unified sigil, it will obey your command like a dragon guarding its precious pearl.

For formal ritual practice at the altar, follow these steps:

First, visualize drawing the Sanskrit sigil into your palms while reciting the Hundred-Word Incantation (a specific mantra). As you rub your hands together, envision heaven and earth inverting, casting the incantation's power into the Heavenly River (Milky Way). Next, visualize this celestial water pouring into the ritual water vessel (a ceremonial tool), imagining the vessel as an ocean while transforming yourself into a divine dragon. Draw up the vessel's water and spray it toward the Heavenly River, creating the majestic spectacle of the Yellow River flowing backward with cascading waves.

The "Concealing Radiance, Veiling the Moon" method requires a white ceramic basin or bowl:

To conceal sunlight, recite the Solar Lord Incantation (a chant honoring the sun) while painting a sun with cinnabar. To veil moonlight, chant the Lunar Lord Incantation (honoring the moon) while drawing a moon with orpiment. Grind soot from a pot's underside into fine powder, mix it with well-drawn morning water to form thick ink, and pour it into the basin as an offering to the sun and moon. Then, write two Thunder God Fulu (empowered talismans) on black paper with black ink to summon the black-robed Envoy Zhang and Marshals Gou and Bi (deities of the Thunder Ministry). Visualize them descending from the Sanskrit sigil of the united sun and moon, treading on dark clouds with swords in hand. After completing the Hundred-Word Incantation and the Darkness Invocation, burn one talisman in the black-water basin. Mix concentrated ink with pot soot, dip a brush into the basin's water while chanting, and trace the talismanic forms of Marshals Gou and Bi in the water while stirring the ashes with the brush. During this, envision heaven, earth, sun, moon, and mountains plunging into darkness.

Next, mobilize the black Qi from both kidneys (considered the reservoirs of Jing/essence in Chinese medicine) and combine it with the baleful energy of the Heavenly Stem (Tiangang) to infuse the water vessel. Hold a mouthful of water and spray it toward the sun-moon direction. Arrange four reed stalks into a cross pattern over the basin and burn one Thunder God Talisman along with Gou and Bi Talismans. Observe as dark clouds and mist rise from the basin, shrouding the cosmos and eclipsing the celestial luminaries.

When inscribing the Gou and Bi Talismans, recite the esoteric mantra: "Om □□□ Lian swiftly descend and manifest" (missing characters represent secret oral transmissions). This incantation rapidly summons the divine marshals' presence.

This scripture details the operational procedures of Daoist Thunder Magic (a secret technique for summoning wind and rain), comprising two main components:

The first part concerns mobilizing internal energies. The practitioner must blend Heart Fire (the Qi of the heart) and Kidney Water (the Qi of the kidneys) in the Middle Dantian (chest region), then direct this combined energy to shoot forth from the eyes, manifesting as two guardian deities. Following this, one must recite specific incantations while visualizing the entire cosmos plunged into darkness—with the sun, moon, stars, and even the obscure celestial bodies Rahu and Ketu (ancient astronomical "hidden luminaries") all enveloped in blackness.

The second part meticulously documents rain-summoning techniques: To conjure storm clouds in the northeast, one must draw a talisman (Fulu) in water using black ink while silently chanting mantras, with focused intention directed northeastward. To disperse clouds, place white paper over the black-water talisman to absorb the ink, causing the clouds above to scatter. To maintain cloud formations, immerse the talisman-writing brush in a water bowl; to completely dispel them, pour the talisman water into a well.

A substantial portion thereafter records temporal secrets for Thunder Magic application, known as the "Six Wu, Six Bing, Six Xin" hour system. Each temporal phase corresponds to specific earthly branch orientations (such as Chen-Si or Yin-You combinations), categorized into six stages: "Emergence, Convergence, Union, Entry, Return, and Storage." Among these, the "Union" phase permits ritual activation, while "Return" and "Storage" phases forbid it. Practitioners must also consider the generative and controlling relationships of the heavenly stems and earthly branches—generative cycles facilitate rainfall, while controlling cycles induce clear skies. Seasonal qi fluctuations (flourishing, active, resting, or imprisoned states) and stellar positions must all be synthesized to precisely regulate precipitation.

The concluding timetable serves as a practical guide, with earthly branch correspondences noted in parentheses. For instance, during the "Six Wu Emergence" phase, the Chen hour aligns with the Si position, while the Yin hour corresponds to You—these combinatorial relationships embody ancient astronomical observations of energetic dynamics.

This scripture records the temporal correspondences and divine orientations in Daoist Thunder Rituals (a form of Daoist practice summoning thunder deities). Using combinations of the twelve Earthly Branches (Zi, Chou, Yin, Mao, etc.), it specifies the positions of thunder deities (Thunder God, Lightning Mother, Wind Lord, Rain Master, and Thunderbolt) on different days.

For example, on Zi days (an ancient dating method), the Thunder God resides in the Zi position (true north), the Rain Master in Mao (true east), the Wind Lord in Wu (true south), the Lightning Mother in You (true west), and the Thunderbolt in Si (southeast). Practitioners must select the corresponding orientation based on the current time period—for instance, facing the Wu position during the Wu hour (11 AM to 1 PM).

The ritual procedure includes: ascending the altar, performing the Pacing the Void and Treading the Dipper (a ceremonial Daoist footwork), burning talismans (Fulu), turning to face away from the temporal orientation, pointing a sword toward the designated direction while reciting incantations to summon storms. Each talisman burning must precisely align with the Thunder God’s or Rain Master’s position to be effective.

The text also details the "Flying Star Method of Piercing Heaven’s Pass," another orientation system correlating the Celestial Stems (Jia, Yi, Bing, etc.) with Earthly Branch positions for specific ritual functions: Jia corresponds to Yin for summoning City Gods and Earth Deities; Yi to Mao for altar arrangements; Bing and Wu to Si for thunder summons, etc. Each direction governs different Thunder Department generals—the Thunder God commands thunder, the Wind Lord controls winds, the Rain Master governs rainfall, while Tangfu invokes clear skies, Guoyin serves sun-seeking rituals, Chujiang facilitates travel, and Ruxiang offers sanctuary.

These intricate directional systems form the "operational manual" for precisely harnessing natural forces in Daoist Thunder Rituals. Practitioners must strictly adhere to these spatiotemporal rules to ensure successful ritual execution.

This scripture discusses the Thunder Method (a Daoist ritual technique for summoning wind and rain, exorcising evil spirits) concerning deity invocation and directional taboos.

It first describes the method of mobilizing the four principal thunder deities (Thunder God, Wind Master, Rain Master, and Lightning Mother) to counter malignant stars and baleful influences. It then enumerates the divine hierarchy of the Five Thunder system: the Five Thunder Direct Envoys (associated with Earth), the Celestial Thunder Court (Metal), the Earthly Thunder Society (Water), and so on—each deity corresponding to one of the Five Phases.

The text details the directional positions of various inauspicious influences:

The Great Baleful Star shifts according to the twelve Earthly Branches—residing in the Xu direction in the first month, the Si direction (associated with the Snake) in the second month, the Wu direction (associated with the Horse) in the third month, and so on. There is also the more complex "Hidden Metal Baleful Direction," calculated using the Sevenfold Celestial Stem-Branch cycles (an ancient calendrical system), with each cycle corresponding to different stellar positions. For example, the first cycle aligns with the Xu, Zhang, Shi, and Zhen constellations.

The movements of the "Seven Luminaries" (Sun, Moon, Metal [Venus], Wood [Jupiter], Water [Mercury], Fire [Mars], and Earth [Saturn]) follow profound and subtle patterns, requiring specific sequential calculations. The text notes that "at midnight, the cycle begins anew from the Zi hour," indicating that all such calculations must commence at Zi (11 PM to 1 AM).

Finally, it lists methods for determining "Suppression and Severance" days (inauspicious days unsuitable for rituals) and the initial constellations for each of the Sevenfold cycles: the first cycle begins with the Xu Sun-Mouse, the second with the Kui Wood-Wolf, and so on. It also records the shifting auspicious and inauspicious directions corresponding to each Luminary’s influence—for instance, when the Sun governs, the Xu constellation’s direction is most baleful; when the Moon governs, the Gui constellation’s direction is most inauspicious.

These details constitute essential knowledge for ancient Daoist practitioners when performing rituals—ensuring efficacy by avoiding baleful directions and selecting auspicious timings and positions.

This passage explains how to determine auspicious directions and timings for performing Thunder Magic (a Daoist ritual for summoning lightning) through celestial observation.

The first section describes the alignment patterns of specific constellations including Venus (Jin), Kui, Yi, Xu, Gui, Ji, Bi, and Di. According to the Pantian Jing (a Daoist classic), distinguishing between divine thunder (shenlei), demonic thunder (yaolei), and ghost thunder (guilei) requires scheduling rituals based on the movement cycles of Venus and the Lou constellation (one of the twenty-eight lunar mansions). Rituals must never be forcibly performed when constellations are obscured or incomplete. Water thunder is governed by dragon deities, demonic thunder by earth gods (sheshen), divine thunder by the Gui constellation, and another type of demonic thunder by the Lou constellation. The Gui constellation corresponds to the Wei earthly branch position (southwest), while Lou belongs to Xu (northwest), both associated with the metal element. Venus governs western baleful energies (shaqi), and practitioners must consult the Thunder Wheel (leilun, a ritual compass) for timing. When either Gui or Lou constellations align with specific directions, one may activate the Golden Tiger Talisman (jinhu fu) to summon thunder deities, taking special care to avoid days when constellations are obscured.

The second section explains the functions of Ji and Bi constellations. The Ji constellation resides in the Yin position (northeast), governing four ke (ancient time units) per shichen (two-hour period). The Bi constellation controls rainfall from the You position (west), sharing this position with Mao and Wei constellations while governing two ke and seven fen per shichen. Practitioners must track these constellations' movements to determine ritual directions—using talismanic documents (fulu) at these positions brings instant wind and rain. The most crucial technique involves applying iron talismans (tiefu) when performing rituals aligned with the Bi constellation.

The third section introduces the "Supreme Ultimate True Calculation" (Taiji zhenshu) method. This numerological system uses nine as its base: combinations like Jia/Ji or Zi/Wu correspond to nine; Yi/Geng or Chou/Wei to eight, and so forth. Specific numerical combinations indicate optimal thunder-summoning moments. For instance, when three nines make twenty-seven, seven becomes the "true number"; subtracting nine from multiples of ten yields the "baleful number" (shashu)—the appearance of this number can summon thunder.

This scripture explains the Daoist Thunder Method techniques for calculating the positions of thunder deities and summoning thunder department generals. It comprises three main components:

First is the numerical method for determining thunder deity positions: Add the Heavenly Stem and Earthly Branch numbers of the year, month, day, and hour. If the sum exceeds 90, subtract 90; if over 10, subtract 9. The resulting numbers—3, 7, and 9—represent destructive forces. These calculations must align with the Five Phases (Water-1, Fire-2, Wood-3, Metal-4, Earth-5) and Bagua (Eight Trigrams) directions (Kan, Li, Zhen, Dui, Center, Kun). When these numbers coincide with inauspicious positions like the Golden Tiger Great Sha or Flowing Fire Malefic Star, thunder will immediately manifest.

Next are the directional patterns for locating thunder generals: The first lunar month corresponds to the Yin direction, the second to the Si direction, and so on in cyclical progression—this constitutes the thunder paths defined by the Purple Mansion Divine Formula. For instance, the seventh month requires searching in the Shen direction. Practitioners must also employ the Mysterious Woman's Heaven-Penetrating method of twelve-hour flying stars, using specific talismanic scripts (Fulu) to accurately summon deities like the Thunder Duke, Wind Earl, and Rain Master.

Finally, the text describes two major sha spirits in detail: The Golden Fire Great Sha manifests with purple-black skin, three eyes, red-gold hair, and crimson robes, holding a state seal in its left hand and a golden halberd in the right, riding a white tiger while commanding thunder gods. The Flowing Fire Malefic Star appears with a blue face and red hair, mounted on a fire dragon wearing flaming red garments, gripping an iron tally in its left hand and a sword in the right, leading fire-hurling thunder deities. Daoist masters must employ specific incantations, hand seals (Jue), and talismans (Fulu) to summon these beings.

(Note: "Flying Gang" refers to the ritual pacing of the stars; "finger seals" (Qia Jue) are Daoist mudras; "visualization" (Cun) denotes the internal cultivation practice of deity contemplation.)

This passage describes the process of performing Fire Method (a thunder summoning technique) in Daoist Thunder Rituals (Leifa):

At the initiation of the ritual, the practitioner visualizes a fiery celestial body resembling the morning sun, crimson as ocean sunrise, while simultaneously reciting incantations, performing Pace of the Dipper (Bugang, a ritual Daoist footwork), and forming mudra hand seals (qiejue). Subsequently, fire talismans (huofu) are burned to invoke the descent of the Star Lords of the Fire Department (huobu xingjun), deities governing flames.

When pointing the ritual sword toward fiery clouds in the sky, one observes flickering flames flowing westward through the Golden Tiger方位 (Jinhu, Daoist directional concept representing the West) before merging into dark clouds. At this moment, myriad deities mobilize according to the ritual command, charging toward the dark clouds. Within the churning darkness, the Thunder Department deities (Leibu shen) arrive in succession, their golden lightning intertwining and clashing with crimson flames.

As the ritual progresses, it simultaneously activates five natural phenomena - wind, clouds, thunder, rain, and lightning - causing even the Five Sacred Mountains (Wuyue) to tremble. Within moments, violent storms manifest, demonstrating Thunder Method's formidable capacity to mobilize cosmic forces. This vivid account illustrates how Daoist ritual masters employ talismans (fuzhou), cosmic pacing, and divine communion to manipulate natural energies through ceremonial performance.
