Often cited as perhaps the best-known Mahayana Buddhist sutra, the Heart Sutra has been chanted daily in Buddhist monasteries in Asia for more than a thousand years. This sutra, the “heart” of the larger Prajna Paramita (Perfection of Wisdom) Sutra, describes the experience of the liberation of the bodhisattva of compassion, Avalokiteśvara, through the insight gained from deep meditation into the fundamental emptiness of all phenomena. With commentary by the Tripitaka Master Hsuan Hua, one of the foremost Tripitaka and Chan masters of Chinese Buddhism in the United States. Translated by Ronald Epstein, PhD.
