Saicho (767-822), the founder of the Tendai School, is one of the great masters of Japanese Buddhism. This edition, which includes a new preface by the author, makes available again a classic work on this important figure’s life and accomplishments. Groner’s study focuses on Saicho’s founding of the great monastic center on Mount Hiei, the leading religious institution of medieval Japan, and his radical move to adopt for purposes of ordination the Mahayana bodhisattva precepts--a decision that had far-reaching consequences for the future of Japanese Buddhist ethical thought, monastic training and organization, lay-clerical relations, philosophical developments, and Buddhism-state relations.
