Banished Immortal 謫仙: The Representation of Exilic Imagery in Bai Yuchan’s Shenxiao Thunder Rites 神霄雷法 and Inner Alchemy Teachings

Bai Yuchan (白玉蟾, 1134?–1229?), a prominent figure of the Southern Lineage of Golden Elixir Sect 金丹派南宗 during the Southern Song dynasty, established a unique synthesis of Shenxiao Thunder Rites and Inner Alchemy by cultivating the persona of a “Banished Immortal”. By framing himself as a celestial thunder officer exiled to the human realm, he grounded his ritual authority in a narrative of divine origin. Central to this system was the “Heart 心,” which served as the essential bridge between internal cultivation and ritual efficacy. Bai argued that the ability to command thunder relied not on mere technique, but on the alchemical refinement of the practitioner’s own spirit and qi 氣/炁. Bai’s writings, especially the Qu Gong Poems 曲肱詩, express his dual identity and his earthly life as a period of spiritual transcendence. Distinctively, Bai embraced genuine emotion and literati aesthetics. He used the “banished immortal” trope to translate the fierce, internal power of thunder into a socially recognized form. This theological and literary construction not only legitimized his public performance of rainmaking and exorcism but also forged a durable identity for the Southern Lineage that continued to shape Daoist traditions well into the Ming dynasty.
