Bernard Faure's previous works are well known as guides to some of the more elusive aspects of the Chinese tradition of Chan Buddhism and its outgrowth, Japanese Zen. Continuing his efforts to look at Chan/Zen with a full array of post-modernist critical techniques, Faure now probes the "imaginaire", or mental universe, of the Buddhist Soto Zen master Keizan Jokin (1268-1325). Although Faure's new book may be read at one level as an intellectual biography, Keizan is portrayed here less as an original thinker than as a representative of his culture and an example of the paradoxes of the Soto school. The Chan/Zen doctrine that he avowed was allegedly reasonable and de-mythologising, but he lived in a psychological world that was just as imbued with the marvelous as was that of his con-temporary Dante Alighieri. Drawing on his own dreams to demonstrate that he possessed the magical authority that he felt to reside also in icons and relics, Keizan strove to use these "visions of power" to buttress his influence as a patriarch. To reveal the historical, institutional, ritual, and visionary elements in Keizan's life and thought and to compare these to Soto doctrine, Faure draws on largely neglected texts, particularly the "Record of Tokoku" (a chronicle that begins with Keizan's account of the origins of the first of the monasteries that he established) and the "kirigami", or secret initiation documents.
