《道法會元》Vol. 66

This passage elucidates the profound meaning of "thunder" (雷霆) in Daoist cosmology, which transcends mere natural phenomena to represent a fundamental manifestation of the Dao's operation.

In the primordial transformation from Wuji (the formless origin) to Taiji (the undifferentiated state of chaos), this mass of chaotic Qi divided into Yin and Yang. The sun embodies the Yang energy governing the celestial realm, while the moon represents the Yin energy ruling the earth, with the North Star mediating between them to harmonize Yin-Yang and oversee the human world. The movements of celestial bodies and the opening-closing dynamics of Yin-Yang ultimately manifest as the vibrations of thunder.

Thunder existed from the very separation of Taiji. Later, sages used the Bagua (Eight Trigrams: Qian, Kun, Zhen, Xun, Kan, Li, Gen, Dui) to symbolize the eight fundamental phenomena between heaven and earth. As the most prominent cosmic force, thunder serves both as an emblem of imperial authority and as the embodiment of spirit transformations.

The essence of thunder comprises three primordial energies: the first is called "Qi of Chaotic Cavernous Great Nothingness" (混洞太无之气), the second "Qi of Crimson Chaos Great Nothingness" (赤混太无之气), and the third "Qi of Dark Silence Mysterious Pervasion" (冥寂玄通之气). These energies alternately transform into sacred scripts, cloud-seal talismans (云篆符咒), revealing the profundity of Daoist methods through cyclical transformations.

Thunder is further classified into three categories: the Thunder of Boundless Infinite Brahma Qi (无极无量梵炁雷霆), the Thunder of Pure Emptiness True Sovereign Clear Qi (清虚真皇清炁雷霆), and the Thunder of Void Chaos Mysterious Unity Luminous Qi (虚混玄一景炁雷霆). These constitute the core creative forces administered by 206 divisions comprising over 90,000 celestial troops—assisting the heavens above while supervising the human realm below, awing the six directions (上下四方), nurturing all life, and eradicating evil.

When concentrated, thunder coalesces as primordial Qi; when dispersed, it manifests as the Five Directional Thunder Deities (east, south, west, north, and center). Contracted, it becomes formless silence; expanded, it assumes concrete manifestations. Authentic thunder methods (雷法) reside not in external calculations but in comprehending the mysterious nature of this primordial energy.

Special mention is made of the "Thunder of Boundless Infinite Brahma Qi" lineage, which commands four great generals, 137 ritual altars, and 720 divine functionaries.

This scripture enumerates the various appellations of thunder in Daoist Thunder Magic (a ritual practice invoking lightning power through talismans and incantations), systematically categorized according to different levels and attributes. These thunder names exemplify Daoism's theological systematization of natural forces.

The first category comprises thunders originating from "Fanqi" (primordial Qi of pre-cosmic origin), including: the Great Chaotic Non-Being Thunder (also called Dongzhen Thunder or Primordial Chaos Thunder), the Illuminating Fortune Thunder (Qingwei Thunder), the Celestial Treasure Thunder, and the Jade Purity Thunder. These thunders correlate with the Three Pure Ones (Yuqing, Shangqing, and Taiqing) in Daoist theology—for instance, the Jade Purity Thunder corresponds to the Celestial Worthy of Primordial Beginning's realm of Jade Purity.

The second category stems from "Qingqi" (pure refined Qi), primarily featuring various forms of "Taiyi Thunder." The Taiyi (Supreme Unity) thunder system is extensive, encompassing over twenty types such as Purple Sovereign Taiyi Thunder, Jade-Green Taiyi Thunder, and Five Blessings Taiyi Thunder. Each represents distinct functions—the "World-Operating Crackling Taiyi Thunder" governs universal movement, while the "Heaven-Shaking Taiyi Thunder" commands awe-inspiring power.

The third category derives from "Jingqi" (luminous Qi), mainly associated with the Shenxiao School (an important Song Dynasty Daoist lineage). This forms a hierarchical thunder palace system: the Divine Empyrean Jade Palace Thunder (subdivided into Divine Wind Thunder, Fire Command Thunder, etc.), the Grand Empyrean Jade Palace Thunder (including Divine Swift Thunder, Blazing Heaven Thunder), the Azure Empyrean Jade Palace Thunder (comprising Eastern Florescence Thunder, Verdant Forest Thunder), and the Sapphire Empyrean Jade Palace Thunder (with Life-Preserving Thunder and Divine Wisdom Thunder). These thunders often serve practical functions like protecting the nation, exorcising evil, and healing diseases.

While these thunder names may appear elaborate, they fundamentally reflect Daoism's sacralization of natural phenomena. Each thunder possesses specific functions and invocation methods, constituting vital components of Daoist ritual systems.

This scripture meticulously records the names and classification system of various thunder deities in Daoist Thunder Magic (a ritual technique that summons thunder department deities for spiritual operations). According to Daoist cosmology, thunders are organized into hierarchical administrative mansions, each governing specific types of thunder with distinct functions:

At the highest level are the Five Jade Mansion Thunder Courts, with each mansion overseeing four thunder types. For instance, the Supreme Scarlet Heaven Jade Mansion governs four thunders including the Wind-Command Thunder and Fire-Cloud Thunder, which correspond to different natural lightning phenomena and symbolize distinct magical properties.

Next is the classification system of the Nine Heavens Thunder Department, comprising two major systems: the Outer-Guard Jade Primordial Thunder and the Pivot-Control Thunder. The former includes eight thunder types such as the Jade Tower Thunder and Judgment-Severing Thunder, while the latter consists of four regulatory thunders like the Pivot-Transformation Thunder and Mechanism-Transformation Thunder.

Further down is the thunder system of the Four Polar Regions: Eastern Fusang Thunder, Southern Danling Thunder, Western Suling Thunder, and Northern Dongyin Thunder, each corresponding to the divine power of the four directional deities.

The most extensive is the Hun Tian Responsive Spirit Thunder from the Purple Tenuity Enclosure (the central administrative region of the celestial realm), encompassing thirty-six "manifestation" thunders. These thunders, all prefixed with the character "演" (manifest), cover the Five Phases (Wood, Fire, Earth, Metal, Water), celestial stems (Jia, Yi, Bing, Ding, etc.), and fundamental cosmic elements like heaven, earth, sun, moon, and stars, forming a complete symbolic system of universal operating principles.

Finally, the Dong Ling Heavenly Origin Thunder from the Supreme Tenuity Enclosure (another crucial celestial region) includes four thunders like the Vast-Heaven Thunder and Vast-Earth Thunder, representing macrocosmic celestial forces. The character "广" (vast) in their names suggests their extraordinarily extensive magical influence.

This scripture enumerates the various thunder deities (Leifa, a Daoist ritual technique invoking thunder's power through talismans and incantations) classified by their distinct attributes. These thunders are systematically categorized according to the Five Phases (Wood, Fire, Earth, Metal, Water), celestial stems (Jia, Yi, Bing, Ding, etc.), the Eight Trigrams (Qian, Kun, Gen, Kan, etc.), cardinal directions, and natural phenomena—each possessing unique powers and ritual applications.

For instance, "Guangchen Thunder" embodies stellar forces, while "Guangmu Thunder" corresponds to the Wood Phase. "Guangqian Thunder" aligns with the Qian trigram of the Bagua. Function-specific thunders include: "Dawen Thunder" for curing epidemics, "Quxie Thunder" for exorcising evil entities, "Yishan Thunder" capable of moving mountains, and "Xingyu Thunder" governing rainfall.

Particularly noteworthy are the thunders associated with the Three Enclosures (Ziwei Enclosure, Taiwei Enclosure, Tianshi Enclosure)—celestial domains in Daoist cosmology. Examples like "Shaowei Enclosure's Dongqing Shenfu Thunder" represent higher-tier celestial thunders. Sacred mountains and rivers also have corresponding thunders, such as "Wuyue Thunder" governing the Five Sacred Peaks and "Sihai Thunder" presiding over the Four Great Rivers.

These thunder appellations reflect Daoism's sacralization of natural phenomena, constructing a comprehensive divine thunder system through meticulous nomenclature. Practitioners of thunder rituals selectively invoke specific thunders through talismans (Fulu) and mudras (hand seals) according to ritual needs, harnessing their cosmic power.

This scripture enumerates the various thunder deities in Daoist thunder rituals (Leifa). Organized according to directional and astrological correspondences, they primarily fall into the following categories:

First are the Five Directional Thunders: the Great Harmony Thunder of the North, the Blazing Thunder of the Southeast, the Scorching Thunder of the Southwest, the Illuminating Thunder of the Northeast, and the Heroic Thunder of the Northwest. Next come the twenty-eight lunar mansions, each associated with a "Celestial Blossom Thunder" from the Horn constellation to the Chariot constellation.

Then follow the Five Directional Resonating Thunders ("kanhe" denoting the harmonious union of heaven-earth and yin-yang): the Blue Heaven Nine Qi Thunder of the East, the Cinnabar Heaven Three Qi Thunder of the South, the White Heaven Seven Qi Thunder of the West, the Mysterious Heaven Five Qi Thunder of the North, and the Yellow Heaven One Qi Thunder of the Center. Here "Qi" refers to primordial vital energy, with the numbers representing different energetic attributes.

Subsequently listed are the Purple Pole Dipper Thunders ("Ziji" denoting the North Star, "Xuanji" the Big Dipper), comprising thirteen grades of thunder, followed by nine grades of thunder associated with the Dipper's Pivot and Dipper's Mechanism. Also included are nine grades of thunder like the Mystic Movement Thunder and Mystic Spirit Flying Transformation Thunder.

The scripture further details special thunders like the Northern True Divine Origin Thunder and Purple Pole Pivot Thunder, along with the Yu-Step Great Commanding Thunder ("Yubu" being the ritual pacing of the stars). Concluding the list are thunders like the Yang Flame Yin Transformation Thunder and North Pole Flowing Heaven Thunder, as well as earth-vein thunders such as the Earth Blossom Thunder and Central Blossom Thunder.

These thunder appellations reflect Daoism's characteristic deification of natural phenomena. In thunder ritual practice and liturgical ceremonies (Keyi), adepts visualize and summon these thunders to exorcise evil, heal illnesses, pray for rain, and avert disasters. Each thunder corresponds to specific directions, constellations, and energetic qualities, possessing distinct functions and symbolic meanings.

This scripture records the various names and hierarchical classifications of thunder deities in Daoist Thunder Rituals (a form of Daoist practice involving talismans and incantations to summon thunder deities). The text begins by listing over twenty distinct thunder deities, such as "Luminous Thunder of Purity and Emptiness" (Qingxu Yaoling Lei) and "Purple Radiance Thunder of Cavernous Clarity" (Dongqing Ziguang Lei). Notations like "Inner Forty/Fifth Rank" following each name indicate their graded positions within the Thunder Ritual system.

The author recounts a personal journey of devotion, beginning with childhood admiration for Daoist arts. After years of sincere practice, he encountered an eminent master from Mount Mei who transmitted the Thunder Rituals to him. When setting up an altar (a sacred space for rituals) to summon thunder generals, he quickly received divine responses. This master bestowed several Thunder Scriptures (texts documenting thunder practices), which were categorized into three grades:

The superior-grade Thunder Scriptures are preserved in the Jade Purity Palace of Supreme Greatness (Gaoshang Dayou Yuqing Gong, a Daoist celestial realm), containing precious talismanic writings passed down since the era of the Three Sovereigns. The middle-grade scriptures were compiled by the Yellow Sovereign (Huangren, a legendary Daoist immortal), while the inferior-grade texts were extracted from immortal classics by successive generations of Daoist patriarchs.

These Thunder Scriptures serve vital purposes: they enable practitioners to beseech celestial blessings for the nation above and assist in relieving the suffering of common people through Daoist arts below. However, the author criticizes those who fail to study deeply—claiming enlightenment upon slight机缘 (opportunities) or focusing solely on the outward forms of talisman-drawing (superficial imitation without grasping true meaning). The passage not only reveals the intricate sophistication of Daoist Thunder Rituals but also emphasizes the necessity of genuine, dedicated cultivation.

This passage elucidates the profound mystical relationship between humans and divine resonance in Daoist practice. It begins by criticizing worldly people who foolishly attempt to summon spirits like "spraying water at stones" (xun shui), being as ignorant as the deaf and blind who cannot distinguish genuine jade from common rock.

The text then reveals how profound scriptures like the Scripture of Celestial Dao (Da Dao Tian Jing) and Secret Thunder Texts (Lei Wen Mijue) have nearly been lost to time. Yet through studying classical records, we understand this fundamental truth: without human participation, the celestial principles of thunder cannot be comprehended; without thunder's manifestation, humans cannot perceive heaven's warnings. Here "thunder" (lei) refers both to natural phenomena and symbolizes celestial punishment and revelation.

The passage marvels at the exquisite subtlety of this mutual resonance between humanity and the Dao, citing the example of Xu Jingyang (the renowned Jin dynasty Daoist Xu Xun) manifesting sacred power in the Wuling region. This illustrates how when a true perfected being (zhiren) appears, there inevitably emerge extraordinary omens like "uprooting cogongrass reveals connected roots" - symbolizing the chain reaction of heaven-human resonance.

The colophon identifies this text as recorded by Huang Yingyan (likely a Daoist name meaning "Thunder Abyss Master") in the Dinghai year, preserved in Compendium of Daoist Methods (Dao Fa Hui Yuan) Volume 66. This exposition primarily articulates the core Daoist concept of "heaven-human resonance" (tianren ganying), emphasizing the cultivated state where practitioners and cosmic energies mutually influence each other.
