Sutra of the Three Heaps

Sutra of the Three Heaps (Skt. Triskhandharma Sūtra; wyl. phung po gsum pa'i mdo) - a sutra used in the confession and purification of transgressions of vows, especially downfalls of the bodhisattva vow. It features the thirty-five buddhas of confession. The 'three heaps' or three sections referred to in the title are 1) homage, 2) confession, and 3) dedication.

Origin of the Sutra

A group of thirty-five monks who had taken the bodhisattva vow accidentally caused the death of a child while they were out begging for alms. They went to Upali, one of the closest disciples of the Buddha, and asked him to request from the Buddha a method of confessing and purifying what they had done. The Buddha then spoke this sutra, and as he did so, light radiated from his body and thirty-four other buddhas appeared in the space all around him. The thirty-five monks prostrated before these buddhas, made offerings, confessed their misdeed, took refuge and re-awakened bodhichitta.
