Агон-сю

Agon Shū believes that it takes its principles directly from the Buddha's teachings, which in the original Sanskrit language are called the Agamas or the Agama Sutras, literally meaning "the teaching of the Buddha". According to Agon Shū, these sutras are the true records of the teachings of Gautama Buddha, whereas Mahayana Buddhism is a deviation from the original teachings of the Buddha.

In 1986, Kiriyama received from the president of Sri Lanka, J. R. Jayewardene, what he believed was a true relic of Buddha. He claimed that most of the other relics of Buddha venerated in Japan were false, and that devotees should pray in their homes before a miniature version of the relic's casket venerated at Agon Shū's headquarters in Kyoto.
