Also known as: Dainichi-kyo

An important Buddhist sutra used in esoteric schools of Buddhism, especially the Shingon sect. This sutra is unusual in that it did not originate from Shakyamuni Buddha, the founder of Buddhism, but was said to have passed straight from Mahavairocana Buddha. It was brought to Japan by Kuukai.

In this sutra, Mahavairocana translates his teachings into ritual forms which form the basis of the rituals in the Shingon School.
