INDIAN TYPES of ethical and philosophical Buddhism did not easily find acceptance in China; it took centuries of contact before a distinctively Chinese adaptation of Buddhism was effected that proved to be congenial to Chinese soil. This Chinese type of Buddhism is called Chan in China, and Zen in Japan, and Zen seems to be the more familiar name for it in America and Europe. Other sects have risen and decreased but they proved to be more or less exotic, they never became indigenous as did Zen. An exception may be suspected in the case of the Pure Land Sects, but it should be remembered that the Pure Land Sects developed from Zen and not independently. To tell the story of this adaptation of the Indian type of Buddhism until it became fixed in the teachings of the Sixth Patriarch, is the purpose of this book. The main part of the book is given over to English Versions of the favorite scriptures of the Zen Sect. To this is added Historical and Literary Introductions and a few notes that seem to be called for to make certain phases of the Sutras more easily intelligible. Let us recall the fact that the knowledge of Buddhism in America and Europe has all come within a hundred years. For seventy-five years of that time it Chan Buddhism in China and Korea and Zen in Japan, for a thousand years, have been powerful in The original texts of these Scriptures are very corrupt, disorderly, loaded with accretions and, in places very obscure. The purpose of the present Versions is to provide an easier and more inspiring reading. For scholarly study students are expected to refer to the more precise translations of linguists. The rules that have been followed in preparing these Versions are as follows: To omit all matter not bearing directly upon the theme of the Sutra. To arrange into a more orderly sequence. To interweave and condense cognate teachings. To interpret obscure words and teachings.
