Goddard presents in one volume a selection of primary source materials from the Theravada, Manayana, Zen, Tibetan, and and other Buddhist traditions. Many of these texts have been more recently translated, but the translations in this book are readable, at the least and they are all in one volume. They are not easy reading and will require many rereadings, but they do present a compliation of basic Buddhist materials for those wishing to benefit from them. My own familiarity with Buddhist texts is primarily with the earlier texts in Theravada Buddhism. This book is comparatively light on Theravada texts but gave me the opportunity to read the texts of other Buddhist Schools.
This is a very fine anthology and is of historical interest for the transmission of the Buddha’s teaching to the United States. This book is a great way to read the original texts. There will be something of meaning in them for you.
