The Linji lu (Record of Linji) has been an essential text of Chinese and Japanese Zen Buddhism for nearly a thousand years. A compilation of sermons, statements, and acts attributed to the great Chinese Zen master Linji Yixuan (d. 866), it serves as both an authoritative statement of Zen's basic stand-point and a central source of material for Zen koan practice.One of the earliest attempts to translate this important work into English was by Sasaki Shigetsu (1882-1945), a pioneer Zen master in the U.S. and the founder of the First Zen Institute of America. At the time of his death, he entrusted the project to his wife, Ruth Fuller Sasaki. Determined to produce a definitive translation, Mrs. Sasaki assembled a team of talented young scholars, both Japanese and Western, who in the following years retranslated the text in accordance with modern research on Tang-dynasty colloquial Chinese.The materials assembled by Mrs. Sasaki and her team are finally available in the present edition of the ""Record of Linji"". The notes, nearly six hundred in all, are almost entirely based on primary sources and thus retain their value despite the nearly forty years since their preparation.
