Known in Chinese as Hua-yen and in Japanese as Kegon-kyo, the Avatamsaka Sutra, or Flower Ornament Scripture, is held in the highest regard and studied by Buddhists of all traditions. Through its structure and symbolism, as well as through its concisely stated principles, it conveys a vast range of Buddhist teachings.

This one-volume edition contains Thomas Cleary's definitive translation of all thirty-nine books of the sutra, along with an introduction, a glossary, and Cleary's translation of Li Tongxuan's seventh-century guide to the final book, the Gandavyuha, "Entry into the Realm of Reality."
