This book contains an English translation of the ancient Chinese translation from the Sanskrit by Buddhatrata in 693 of the Sutra of Complete Enlightenment, an important text in Mahayana Buddhism. Approximately 4/5 of the book consists of a commentary on the sutra by the Ch'an master Sheng-yen. To be completely honest, I found the sutra itself to reek of church scholasticism and the, to my mind, totally unnecessary and enormously complicated metaphysics typical of a certain kind of Indian thinking. However, the commentary is beautifully to the point and concrete. This, I find, is typical of a certain kind of Chinese thinking. :) One star for the sutra, 5 stars for the commentary!
