The 35 Buddhas are known from the Sutra of the Three Heaps, popular in Tibetan Buddhism. This Mahayana sutra actually describes a practice of purification by confession and making prostrations to these Buddhas, and is part of the larger Stack of Jewels Sutra.
It is a Mahayana ritual used primarily by monks and nuns for the purpose of confession of downfalls which means transgressions against the vinaya and bodhisattva vows. The central object of worship is the Thirty-five Confession Buddhas, including Shakyamuni Buddha. The name of the sutra follows from the three principal sections of the text: 1) homage, 2) confession, and 3) and dedication.
