The Diamond Sutra, or the Perfection of Wisdom, which cuts like a thunderbolt, is one of the cornerstone texts of Mahayana Buddhism and provides a summary of the core concepts of the Buddha. The Heart Sutra, perhaps the most important of all Buddhist texts, sets out to formulate the very heart, or essence of perfect wisdom and is studied with special reverence in Zen monasteries and the Tibetan Buddhist lamaseries.

Edward Conze, who was until his death in 1979 a powerful force for introducing Buddhism and its sacred texts to the West, has provided these translated key texts with an extensive commentary for the easiest possible appreciation phrase by phrase. For this new edition, Judith Simmer-Brown, a well-known American scholar of Buddhism, has contributed a lively, context-setting introduction.
