A remarkable collection of essays, Sh b genz , Treasury of the Eye of True Teaching, was composed in the thirteenth century by the Zen master D gen, founder of the S t Zen school in Japan. Through its linguistic artistry and its philosophical subtlety, the Sh b genz presents a thorough recasting of Buddhism with a creative ingenuity that has never been matched in the subsequent literature of Japanese Zen. With this translation of thirteen of the ninety-five essays, Thomas Cleary attempts to convey the form as well as the content of D gen's writing, thereby preserving the instrumental structure of the original text. Together with pertinent commentary, biography, and notes, these essays make accessible to a wider audience a Zen classic once considered the private reserve of S t monks and Buddhologists. Readers from many fields in the sciences and humanities will find themselves richly rewarded.
