《道法會元》Vol. 117

This passage comes from the Taiji Dulei Yinshu (Hidden Text of the Supreme Ultimate Thunder) in the Daofa Huiyuan (Collected Essentials of Daoist Ritual). It primarily explains how to summon various thunder deities and nature spirits through incantations to perform thunder magic (Daoist rituals for controlling weather and exorcising demons).

The opening describes the primordial chaos of the universe, where the Taiji (Supreme Ultimate, the highest ontological principle in Daoism) revolves within emptiness, dividing into the two energies of Yin and Yang (the Two Modes), which then generate the Three Powers (Heaven, Earth, and Humanity) and the Five Phases (Wood, Fire, Earth, Metal, Water), forming the cosmic structure of the Four Symbols and Seven Stars.

The text then enumerates the titles and directions of numerous thunder deities: Marshal Tianpeng (the Northern Dipper deity), Tianchong, Tianfu, and the other nine stellar generals of the Dipper, as well as the Thunder Kings of the five directions—east, south, west, north, and center—each corresponding to a different Qi of the Five Phases (for example, the nine Qi of the east belong to Wood). It also mentions natural deities such as the Thunder Duke and Lightning Mother, the Great Spirit of Swift Fire and Divine Command (the enforcer of thunder justice), the Earl of Wind and Master of Rain, as well as thunder gods corresponding to the Eight Trigrams (Qian, Kan, Gen, Zhen, Xun, Li, Kun, and Dui).

The latter half details the summoning of thunder deities associated with the twenty-four solar terms, starting with the Thunder God of the Beginning of Spring and proceeding in sequence through Rain Water, Awakening of Insects, Spring Equinox, and so on, up to the Thunder God of Minor Cold, urgently calling them to manifest their power. The repeated use of "arise swiftly" is a common technique in Daoist incantations to amplify ritual efficacy, where the continuous invocation of divine names creates a powerful summoning force.

The core of this thunder ritual lies in mobilizing the cosmic Qi of the Five Phases, harnessing the natural power of seasonal transitions, and commanding the collective action of the thunder deities. When practitioners recite this divine incantation while holding the ritual seal (a sacred emblem), they must combine it with specific visualization (meditative focus) and hand mudras (ritual gestures) to achieve the magical effect of "rousing the dragon thunder and summoning wind and rain."

This passage describes the intricate ritual procedures of Daoist Thunder Magic (Leifa), a practice for summoning thunder and lightning, which requires specific hand gestures, incantations, and celestial alignments.

The practitioner begins by moving the ritual brush from the Yin position (northeast), tracing twenty-four revolutions of talismanic script (Fulu), or marking twenty-four specific directional points around the perimeter. Next, the Twenty-Eight Lunar Mansions (such as Jiao, Kang, Di, etc.) are arranged in a precise sequence, starting from the Chen position (southeast), forming an array around the Five Fires talismanic characters. This is accompanied by mudras (ritual hand seals) and the silent recitation of the Five Thunder Emperors' incantation.

The brush is then moved in twelve revolutions while facing the Li position (south), reciting the Five Sacred Mountains Thunder Lords' spell, followed by an alternating Thunder Lord chant. When releasing the talisman, the practitioner first rotates clockwise toward the Xun position (southeast), then counterclockwise toward the Kun position (southwest). References to "Taichu" (Primordial Beginning) and "Taiji" (Supreme Ultimate) denote different hierarchical thunder deities, including the Thunder Emperor and Thunder Kings, who mobilize celestial troops.

The incantations depict the awe-inspiring spectacle of the Thunder Pantheon in action: dark Qi (vital energy) swirling, poisonous winds howling, thunder drums shaking the heavens, and lightning flashing—capable of vanquishing malevolent spirits and subduing dragons, serpents, and fierce beasts. The imagery of fiery wheels and chariots symbolizes the overwhelming power of Thunder Magic to eradicate calamities. The phrase "Swiftly, swiftly, as commanded by the Dao Ancestor, the Thunder-Sounding Great Emperor!" urges the thunder gods to descend rapidly.

The ritual further employs the Eight Trigrams (Qian, Kan, Gen, Zhen, etc.) and Earthly Branches (Yin, Chou, Mao, etc.) to structure the sacred formation, emphasizing its function to "capture and bind unrighteous spirits alive." The text also explains how different stellar combinations produce distinct effects: the Yi and Zhang Mansions govern thunder and lightning, the Ji and Bi Mansions control wind and rain, while the Di and Liu Mansions can be used for healing. During practice, twelve clockwise rotations at specific stellar positions are performed, followed by eight additional revolutions to summon wind, clouds, thunder, and rain.

This scripture describes the Thunder Method (Leifa) system of Daoist ritual practice, detailing the pantheon of Thunder Deities and their ceremonial protocols.

The text first enumerates the eight directional Thunder Generals with their respective domains: General Liu Jiyang of Eastern Jade Treasure Cloud Thunder, General Xian Yongqing of Southern Mysterious True Gate Lightning, General Bai Zigeng of Western Supreme Subtlety Wind Pursuit, General Ren Zihe of Northern Mysterious Upper Rain Gathering, and four others guarding each cardinal direction. Above these eight cloud-thunder generals, talismanic inscriptions (Fulu) must be written according to the Eight Trigrams (Bagua) arrangement (Qian, Kan, Gen, Zhen, Xun, Li, Kun, Dui) to mobilize the primordial fires from all directions.

Subsequently, the thunder-summoning incantation is recorded: first invoking the Thunder God (Leigong) to raise dark winds, strike iron drums from four directions, and activate the pulse of heaven and earth's Qi, compelling the Azure Dragon (symbolizing thunder forces) to descend with the ritual master. The chant vividly depicts the manifestation of thunder magic—stars fading, auspicious Qi rising, five seas responding, thunder shaking heaven and earth, flying sand and rolling stones, with fire dragons descending to annihilate all malevolent spirits and demonic entities.

The concluding section outlines directional taboos for ritual performance: specific years require thunder rituals to be conducted in particular orientations (Kun direction due south, due east, etc.), mentioning the use of "Dragon-Piercing Talismans of Execution." The text emphasizes adhering to the primordial Dao-power of "Primal Chaos" (Taichu Hundun), executing thunder punishments strictly according to the liturgical laws established by the Daoist Patriarch.

[Note: The "Five Emperor Thunder Gods" refer to thunder deities governed by the Five Directional Thearchs; "Eight Trigrams" denote the fundamental directions (Qian-heaven, Kan-water, Gen-mountain, Zhen-thunder, Xun-wind, Li-fire, Kun-earth, Dui-lake); while "Thunder God, Lightning Mother, and Wind Earl" are traditional deities governing thunderstorms in Chinese mythology.]

This scripture records the names of thunder deities and summoning incantations from Daoist Thunder Magic (a secret art invoking thunder deities to perform rituals). It enumerates the powerful thunder gods (Manlei) from all directions, including those from the south, west, north, and all eight cardinal points, as well as thunder deities from the upper and lower realms.

Next, it mentions the Dragon-Subduing Generals from the Six Jia and Six Ding (a system of Daoist guardian deities), corresponding to the ten celestial stems (Jia, Yi, Bing, Ding, etc.), along with the Command Messengers (divine envoys who deliver orders). The text then lists the various colored thunder Qi (lightning energy) associated with the Nine Stars of the Northern Dipper (such as Tianpeng, Tianfu, and other stellar lords), including blue thunder, red thunder, white thunder, and others. It explains that to amplify the wind’s force, one must first write the character for "thunder" (雷) before adding the character for "wind" (风).

A notable section describes the system of Twelve Thunder Lords, divided into three categories: twelve from the Celestial Thunder Division, twelve from the Earthly Thunder Division, and twelve from the Human Thunder Division. Following this, the text invokes the Supreme Thunder Ancestor (the highest deity of the thunder pantheon) to descend swiftly, using the eight trigrams (Qian, Kan, etc.) as directional markers. In the command section, a decree (Chiling, the highest Daoist directive) summons the thunder gods to gather and unleash the might of thunderbolts.

Finally, the scripture records the names of several special types of thunder: Du Thunder, Divine Thunder, Celestial Thunder, Dragon Thunder, Water Thunder, and others. It also explains the method of using the "Xuhuo Talisman" (a thunder-summoning charm), noting that it must be activated in conjunction with the "Mulang Incantation" (a thunder-calling spell). Additionally, it documents the correspondences between wind, rain, thunder, lightning, and specific constellations (such as Ji Star and Liu Star), as well as a fragment of the "Divine Empyrean Jade Mansion Incantation" (a key Thunder Magic spell from the Shenxiao tradition). This passage describes the Ten Directions’ Celestial Warriors (guardian deities) clad in jade-green armor, girded with dragon-patterned belts, and wearing tiger-head scarves.

This is a Daoist talismanic document for summoning thunder and praying for rain, detailing the specific procedures for performing thunder rituals to invoke precipitation.

The document begins with the invocation "By the decree of the True King of Divine Empyrean," indicating its authority from the highest thunder deity in Daoist cosmology. It summons the Five Directional Thunder Kings, deities of wind, clouds, thunder, rain, lightning and fire, as well as dragon kings from all lakes and seas, commanding them to immediately follow the talismanic order to bring rain and relieve drought. The conclusion emphatically states "Execute swiftly without delay," bearing the authoritative seal of the "Great Emperor of Primal Yang."

The operational method requires: preparing an iron plate measuring 1 chi 2 cun in length (adding 1 cun in leap years), 4 cun in width, and 5 fen in thickness. The Daoist priest performs Gangbu stepping (a ritual Daoist footwork pattern) while inscribing talismans at specific cardinal directions. The completed talisman must be sealed in a yellow silk pouch, inscribed with the priest's religious name and personal name, then stamped with ritual seals. After selecting an auspicious date, the priest arranges an altar formation below the ritual platform, summons thunder deities to circle the altar three times, then casts the talisman toward a designated direction.

The incantations include summoning deities like the "Sea God of Celestial Origin," "Azure Elder Tiger Mother," and "Lord Axiang" - the legendary deity who pushes the thunder chariot. The chant vividly describes the drought's devastation: "Flames blanket the wilderness, all beings grieve; green waters turn to arid plains, blue mountains rise in dust," expressing the people's desperate longing for rain.

Finally, the priest forms a thunder hand-seal with the left hand, burns the "Sudden Fire Talisman," simultaneously performs Gangbu stepping while kicking toward the Bi constellation (one of the 28 lunar mansions), praying for "black rain from azure skies" to descend. The entire ceremony integrates multiple Daoist ritual elements including talismans, incantations, sacred footsteps, and mudras (hand gestures), demonstrating the complete thunder ritual process for rainmaking in Daoist practice.

This scripture records multiple incantations and hand seals used in Daoist rainmaking rituals, belonging to the secret techniques of Thunder Magic (Leifa) within Daoist esoteric practices. Each incantation concludes with invocations of specific deity names and the standard phrase "急急如律令" (jí jí rú lǜ lìng, "swiftly obey this command as if by law"—a common Daoist incantation finale demanding immediate execution).

The first incantation summons supreme Daoist deities like Taiyi (the Supreme Unity) and Yuchen (an epithet of Yuanshi Tianzun, the Celestial Venerable of the Primordial Beginning), using iron talismans (tie zha, ritual paper) to invoke thunder generals, dragon gods, and water spirits. "负舟" (fù zhōu) refers to the water god Han Bo, while "元精" (yuán jīng) denotes the quintessential essence of water. It further calls upon the Three Luminaries (sun, moon, and the Tian Gang constellation), commanding the River Lords of the Nine Jiang and the Nine Dragon Gods to swiftly bring nourishing rain.

The second incantation, issued under the decree of Yuanshi Tianzun from the highest Jade Pure Realm (Yuqing jing, foremost of the Three Pure Realms), shakes the dragon courts into submission. It mobilizes the Five Thunders (representing the Five Phases: Metal, Wood, Water, Fire, and Earth) and celestial troops. The text vividly describes the convergence of wind, rain, and thunder as heavenly mandates (tian fu) descend in torrential downpours, emphasizing Thunder Magic's social function: "the wicked perish while the virtuous flourish."

The third incantation focuses on the Taiyi pantheon: the hidden Taiyi deity within thunderlight, the Venus Star God (Haoweng), and primordial goddesses (yuanjun), commanding them to balance water and fire. "Han Bo bearing his boat" reappears, cooperating with the Three Officials (Heavenly, Earthly, and Water Officials) and Five Thearchs (deities of the five directions) to orchestrate rainfall.

The fourth incantation features the Purple Void Primordial Goddess (Zixu Yuanjun, a high-ranking female immortal) directly ordering rain deities, warning supervising envoys against delay lest she report their negligence to the celestial court. The final incantation stands out with its mythological narrative: it recounts the legend of slaying the White Tiger (symbolizing drought demons) with divine white bamboo crossbows, mentioning a coiled divine creature in emerald pools—an allusion to dragon gods.

The ritual requires specific mudras (such as the "double-handed rotation while pacing the Dipper Steps," a reference to the Yu Steps star-walking technique) and silent recitation while covering one's ears. These incantations exemplify Thunder Magic's principle of "using spirit to command Qi, and Qi to mobilize spirits," demonstrating how Daoism regulates nature through coordinated invocations of deities across hierarchical realms.

This scripture depicts a thunder ritual (Leifa) in Daoist practice—a method of summoning thunder deities through incantations and talismans. The opening passage vividly portrays the awe-inspiring power of the Thunder Department deities: their gaze flashes like lightning through the Water Palace (abode of aquatic spirits), their breath rumbles like thunder, while the flood dragons that once aided Yu the Great in taming the waters now lie dormant. The imagery of the "Crimson Dragon and White Tiger" (symbolizing the dual forces of Yin and Yang) locked in combat under the bright moon, and the Yellow River flowing backward, illustrates the gathering momentum of celestial thunder power.

The latter half consists primarily of invocations summoning the Thunder Department pantheon. First, it enumerates the highest Daoist deities—the Three Pure Ones (Yuqing Yuanshi Tianzun, Shangqing Lingbao Tianzun, and Taiqing Daode Tianzun)—alongside the Jade Emperor and other revered figures. The focus then shifts to summoning thunder deities, including the Emperors of the North and South Poles, the Three Officials (Heavenly, Earthly, and Water Officials), and the Thunder Ancestor Emperor. The incantation repeatedly emphasizes the command "Swiftly, swiftly, in accordance with the statutes and ordinances!" (a directive for immediate execution), ordering the Thunder Duke and Lightning Mother, along with the Five Directional Thunder Kings (thunder deities of east, south, west, north, and center), to mobilize celestial troops without delay. They are instructed to shatter mountains, summon storms, and eradicate all demonic forces. The passage concludes by invoking the marshals of the Divine Empyrean Palace (the highest authority of the Thunder Department) to swiftly carry out their demon-slaying missions, while the Twenty-Four Solar Term Thunder Kings (thunder spirits corresponding to each solar term) are also urged to act with haste.

This incantation embodies the Daoist thunder method's core principle of "harmonizing the microcosm of the human body with the macrocosm of heaven and earth." Through ritual incantations and specific ceremonies, it seeks to harness nature's most formidable thunderous power to subdue evil, aid the living, and fulfill the Daoist ideal of universal salvation.

This scripture describes the talismanic incantations and rituals for summoning thunder deities in Daoist Thunder Magic (a ritual practice for invoking storms and rain).

The Celestial Court (Golden Palace) issues its majestic decree—thunder resounds mightily, shaking heaven and earth. The sacred script on the jade talisman (a Daoist ritual instrument) is inscribed with clearly defined strokes. When the first incantation is recited, the sky darkens; at the second, the sun vanishes; by the seventh recitation, lightning flashes and thunder roars. The moment the golden talisman descends, all demons and malevolent spirits are instantly vanquished, reduced to dust. This ritual is performed in accordance with the edicts of the Dao Ancestor (Lord Lao, the Most High) and the Great Emperor of Resonating Thunder.

The text then enumerates the titles and duties of thunder deities from all directions: beginning with the Primal Thunder Deity from the dawn of creation, followed by the Ten Directional Thunder Kings—East, South, West, North, Southeast, Northeast, Southwest, Northwest, Above, and Below. Each Thunder King commands the clouds and wields thunder, shaking the cosmos.

When beseeching clear skies, one may summon these Thunder Kings to swiftly disperse the overcast clouds and restore the radiance of the sun and moon. The specific Thunder Kings invoked include: the Thunder King of the East, the Thunder King of the South, the Thunder King of the West, the Thunder King of the North, the Thunder King of the Center, the Thunder King of the Southeast, the Thunder King of the Northeast, the Thunder King of the Southwest, the Thunder King of the Northwest, the Thunder King Above, and the Thunder King Below.

Similarly, when praying for rain, these same Thunder Kings may be summoned to densely gather dark clouds and send down auspicious snow. The scripture sequentially lists the functions of the Thunder Kings of the East, South, West, North, Center, Southeast, Northeast, and Southwest in summoning clouds and bringing snowfall.

This scripture describes the ritual summoning of thunder deities in Daoist Thunder Magic (Leifa), a ritual system centered on commanding thunder to exorcise evil. The "Thunder Kings" mentioned are deities who govern lightning and thunder, stationed in the eight cardinal directions along with the zenith and nadir, forming an impenetrable celestial net.

The Thunder Kings of the east, south, west, north, southeast, northeast, southwest, and northwest—along with those of the heavens above and the earth below—unleash their divine power simultaneously. They summon dark clouds and auspicious snow, wielding thunderbolts to vanquish malevolent spirits. In particular, they target demonic entities lurking in ruined temples, launching thunderous assaults with rolling clouds and flashing lightning.

Next, the scripture calls upon the Eight Trigrams Thunder Kings (corresponding to the Bagua—Qian, Kan, Gen, Zhen, Xun, Li, Kun, and Dui). These deities capture all manner of unruly specters, including drought demons (Hanba Jing) that cause famine, rain spirits (Yu Jing) that bring unnatural downpours, and plague-inducing snow spirits (Xue Jing). The seven star-lords of the Big Dipper—Tanlang, Jumen, Lucun, Wenqu, Lianzhen, Wuqu, and Pojun—also descend to assist in subduing unrighteous gods.

The text then enumerates twelve specialized Thunder Gods: the Five Directions Thunder Gods, Four Commands Thunder Gods, Six Jia Thunder Gods, Pili (Shattering) Thunder Gods, Water-Releasing Thunder Gods, Eight Winds Thunder Gods, Ten Rains Thunder Gods, Enemy-Smashing Thunder Gods, Lightning Thunder Gods, Cloud-Summoning Thunder Gods, Rain-Bringing Thunder Gods, and Mountain-Moving Thunder Gods. Joining them are the divine generals of the Five Sacred Peaks (Wuyue). Clad in golden armor and wielding celestial weapons, their mere presence forces demons to flee.

Finally, three principal commanders are specially summoned: the Mysterious True Lightning General of the south, capable of infinite transformations and wielding fiery wheels, and the Supreme Subtle Wind-Chasing General of the west, who stands in the void to slay demons. Every summoning concludes with the urgent command: "Swiftly obey the Thunder Decree of the Dao Ancestor!"—signifying that this ritual is enacted under the supreme authority of the Most High Dao Ancestor (Taishang Daozu), the highest deity in Daoism.

This scripture is a Daoist incantation for exorcising evil spirits and vanquishing demons, describing the process of summoning celestial generals from all directions to subdue malevolent forces. The text sequentially invokes five divine generals according to their cardinal positions:

First is the Great General of Gathering Rain from the Mysterious North (Xuan Shang Ji Yu Da Jiang). This general traverses heaven and earth, pervading all realms, specializing in eradicating yin-based wickedness and severing the gateways through which ghosts and demons pass. Wherever his sacred talismans (fulu) reach, demonic qi is instantly captured.

Next comes the Great General of Kindling Flames from the Life-Giving Southeast (Hao Sheng Liu Huo Da Jiang). Radiating majestic power, he ascends directly to celestial realms, joining the Mysterious Perfected One (Xuan Zhen, a Daoist deity) of the South to subdue demons until their forms dissipate. His spiritual efficacy manifests with swift certainty when invoked.

The third is the Great General of Transcendent Mysteries from the Northeast (Du Xian Xuan Yuan Da Jiang). Moving unpredictably like the primordial Dao-Qi itself, he swiftly dispels demonic influences and severs the vital essence (jing) of ghosts. No evil can linger where his talismans appear.

Fourth is the Great General of Spirit-Devouring from the Southwest (Tai Ling Tun Mo Da Jiang), also called the Nine-Qi Divine Lord. His luminous aura penetrates all dimensions, resonating with heaven and earth's true spirits, specializing in capturing demonic entities while protecting the souls of the living.

Lastly, the Great General of Infinite Ghost-Purging from the Northwest (Wu Liang Qu Gui Da Jiang) commands celestial troops through all realms, expelling evil and executing demons to safeguard the nation and its people. Any ghost encountering him meets certain annihilation.

The scripture then commands the activation of sacred fires: celestial fire, earthly fire, samadhi fire (inner fire cultivated through neidan practice), thunder fire, lightning fire, seven-star fire, and crashing-fire—all unleashed simultaneously to overwhelm malevolent forces.

The concluding section enumerates seventy-two Thunder Dukes (Hou Lei Gong), storm deities named after the seventy-two pentads of the twenty-four solar terms—such as "Thunder Duke of East Wind Melting Ice" and "Thunder Duke of Hibernating Insects Stirring"—signifying the mobilization of all thunder deities across creation to assist in the exorcism.

This scripture describes the seasonal manifestations of the Thunder God (a divine general in the Daoist Thunder Department) throughout the twenty-four solar terms, along with invocational mantras for summoning thunder deities.

The first half follows the annual cycle of solar terms, each accompanied by natural phenomena revealing the Thunder God's presence: when the pinellia herb grows, the Thunder God brings warm winds; as crickets hide in wall crevices, he manifests through hunting falcons; when decaying grass transforms into fireflies, he ushers in humid summer heat. These descriptions embody the Daoist cosmology of "cosmic resonance between heaven and humanity," linking natural phenomena with divine power.

The latter portion contains thunder magic (Daoist thunder-summoning techniques) command mantras, including:

1. Summoning Thunder Department deities: the Celestial Thunder Generals, Lightning Mother, Wind-Fire Wheel Generals, and all thirty-six Thunder Department marshals

2. Descriptions of thunder's formidable powers: commanding sandstorms, controlling weather, awing mortal souls

3. Special mention of the Wind-Rain Ministers (high-ranking immortals governing weather) from Penglai Paradise and the White-Haired Venerable Spirit (a Thunder Department deity) wielding an iron battle-axe

4. Concluding with "urgently and lawfully commanded" (a standard Daoist mantra ending indicating immediate enforcement)

Appended are Three Tribulations Fulu (Daoist ritual documents for deity summons), demanding the Four Directional Demon Kings mobilize upon receiving the command—gathering thirty-six thunder generals, eight trigram deities, and all thunder troops. "Golden Tiger of Great Malice" refers to the western inauspicious deity, while "Prosperous Qi Poison Thunder" denotes venomous thunderbolts—both representing powerful thunder magic marshals.

This scripture describes the procedures and incantations for Daoist Thunder Magic (a ritual technique for summoning lightning). The main content is divided into several sections:

First is the summoning of Thunder Ministry deities, including the Thunder Kings, Thunder Officials, and divine soldiers such as Marshal Deng, Judge Xin, and Messenger Zhang from the Thunder Pantheon. The practitioner must reverently follow the commands of the True King (one of Daoism's supreme deities) and the Thunder Emperor, using talismanic spells to summon wind, rain, and thunder.

Next are the specific ritual steps: The practitioner must inscribe the talismanic decree at an auspicious time (determined by year, month, day, and hour), tread the Eight Trigrams Gang Steps (a Daoist ritual footwork), and recite mantras such as "Om Honghong Han Nanyan Qian Yi Chi." The incantations reference the functions of each trigram palace: the Dui trigram commands mighty troops, the Gen palace seals ghostly gates, the Li palace steers fiery wheels, etc.

Following this are the invocations for summoning Thunder Gods: "By the mandate of the Purple Tenuity Lord, I summon the Thunder Ministry deities—Thunder Gods swiftly ride the flying clouds!" This is accompanied by hand mudras (Thunder Seals) drawn from the knees and pointed toward the Xun position (southeast). Additional incantations like "By the decree of the Jade Emperor" are recited to hasten the arrival of Thunder Messenger Zhang.

The concluding section reveals the celestial calculations for Thunder Magic: Based on the winter or summer solstice, practitioners count forward or backward through the Twenty-Eight Lunar Mansions to determine auspicious positions. The text provides examples for calculating proper directions and timings after solar terms like the Waking of Insects, Spring Equinox, and Great Heat—locating the position of the "Net" constellation (one of the lunar mansions) being crucial for successful Thunder Magic practice.

The Virtuous Fortune Imperial Star represents auspicious celestial influences, while the Flowing Fire Malefic Star signifies inauspicious omens—reminding practitioners to heed stellar portents. The entire ceremony must strictly follow celestial timing, spatial orientation, and ritual formulas to successfully summon the Thunder Ministry deities.

This scripture expounds the essential secrets and taboos of Daoist Thunder Magic (a ritual technique for summoning winds/rains and exorcising evil). The key teachings can be summarized as follows:

Regarding methods for calculating auspicious/inauspicious directions: In Yang years, one must position the Grand Duke (Taisui, the year's governing deity) at the Prime Origin (Yuanchen, an auspicious deity). In Yin years, the position immediately preceding Taisui is used instead. The precise operation requires calculating the positions of the "Four Thearchs" (sifang tiandi, celestial rulers of the four directions) based on the year, month, day, and hour. Mastering this secret enables avoidance of misfortune and attraction of blessings.

Special emphasis is placed on the significance of the Thearch Star (dixing, celestial ruler's stellar manifestation): wherever this stellar deity resides, all malevolent forces retreat—even the Thunder Duke and Lightning Mother dare not transgress. But miscalculations render even august deities like the Yellow Emperor (Xuanyuan Huangdi) powerless to assist. Particularly for grave operations like dismantling heterodox shrines (po miao zhu tan), directional discernment becomes crucial.

Key principles of Thunder Magic application: When employing thunderous power for exorcism, rain-making, or weather clearing, conventional methods relying on Kan-Li (the Water-Fire trigrams) become unnecessary. The true secret lies in comprehending the mysteries of "startling thunderclaps" (pili jinglei) and "sudden flashes" (shuhu huoguang). These wind-thunder techniques are supremely precious and rarely transmitted.

Critical taboo dates: Special periods like the "Six Wu" (liuwu) and "Six Si" (liusi) days are enumerated—times when thunder deities enter quiescence and Thunder Magic must not be recklessly employed. For instance, during "Six Wu" days the thunder-dragons convene, while "Six Ding" days find thunder spirits in retreat. Practitioners must memorize these prohibitions.

Calculation mnemonics: Verses like "Jia-Ji follow the sheep, Ding moves counter" preserve directional reckoning methods transmitted by the Shangqing school's Left Yang Brilliance Palace (zuo yangming gong, an important Daoist sanctuary). These guide adepts in choosing progressive or regressive orientations according to heavenly stem days.

Final emphasis on Thunder Magic's sanctity: This text identifies the methods as core Shangqing (Highest Clarity) secrets—profound mysteries personally transmitted by the Jade Emperor (Yuhuang Dadi). Proper implementation requires precise talismanic incantations (fuzhou) to truly commune with heaven-earth, achieving "summoning clouds/thunder in one's palm, beckoning winds/rains before one's eyes." The scripture solemnly cautions: the magic never fails—only practitioners who lack authentic transmission will falter.

This scripture expounds the core secrets and talismanic applications of Daoist Thunder Magic (a ritual art for summoning wind and rain, exorcising demons). The main content is divided into several sections:

First, it mentions how the celestial stem "Yi" represents the fundamental power of thunder. By mastering this secret method, one's drawn talismans (Fulu) and recited incantations will take immediate effect—even ghosts and deities can be reduced to dust by the thunder's might. Here "Pili" refers to the most formidable thunderbolts.

The text then meticulously records five sets of celestial stems and earthly branches (Jia-Si, Yi-Geng, etc.) corresponding to specific ritual directions and hand mudras (Gangbu steps). For instance, on Jia-Si days, one must follow the "Sheep" position (Wei Palace) for Gangbu steps while working counter to the "Gui" position; on Yi-Geng days, practitioners should follow the "Tiger" position (Yin Palace) for Gangbu steps while opposing the "Kun" position. These techniques require secret transmission from masters, being precious methods passed down by banished immortals (Zhexian).

The subsequent "Nine Heavens Concealment" section reveals more advanced Thunder Magic secrets. For example, on Jia-Si days one follows the "Snake" position (Si Palace) for Gangbu steps while working counter to the "Jia" position; on Yi-Geng days, practitioners follow the "Rat" position (Zi) while opposing the "Xin" position. The scripture emphasizes that as long as celestial prohibitions aren't violated, these methods can instantly produce results whether praying for rain or clear weather.

Finally, it states that those who truly master these Thunder Magic secrets will earn respect from heavenly immortals and inspire fear in ghosts and spirits. The term "Blood Blade" here likely refers to a particularly powerful Thunder Magic ritual implement or talisman. Overall, this passage transmits the core Thunder Magic secrets concerning the harmonious interplay of timing, spatial orientation, and talismanic application in Daoist practice.
