"Zen Letters " presents the teachings of the great Chinese master Yuanwu (1063-1135) in direct person-to-person lessons, intimately revealing the inner workings of the psychology of enlightenment. These teachings are drawn from letters written by Yuanwu to various fellow teachers, disciples, and lay students--to women as well as men, to people with families and worldly careers as well as monks and nuns, to advanced adepts as well as beginning students. A key figure of Zen history, Yuanwu is best known as the author of "The Blue Cliff Record. " His letters, here in English for the first time, are among the treasures of Zen literature.
