A Historical Practice, Described Without Instruction

Sokushinbutsu, becoming a buddha in this very body, names a historical ascetic practice undertaken by a small number of Japanese practitioners, chiefly monks associated with the Shingon linked Yudono mountain tradition of the Dewa Sanzan in northern Japan, across roughly the eleventh through the nineteenth centuries, in which an ascetic undertook years of graduated, severely restrictive dietary and physical discipline intended to culminate in death under conditions the practitioner and tradition believed would preserve the body from ordinary decomposition, resulting in what practitioners and later devotees regarded as a self mummified buddha. The practice sits within a broader current of Japanese Buddhist and Shugendo ascetic tradition emphasising extreme physical discipline as a path to spiritual attainment, and it must be understood, and is recorded here, strictly as a documented historical practice belonging to a specific, now discontinued tradition rather than as material of any instructional value: the atlas describes its history and religious meaning and gives no procedural detail, consistent with the practice's inherently life ending nature and its status today as entirely historical rather than living.
