Daishin ［大進］ (n.d.): A Japanese priest, commonly known as Āchārya Daishin (Daishin-ajari). A priest and disciple of Nichiren. Born in Shimōsa Province, he is believed to have been a relative of the Soya family. He and Nisshō, later one of the six senior priests designated by Nichiren, taught and guided the believers in Kamakura while Nichiren was in exile on Sado Island. From a letter Nichiren wrote to Soya Dōsō, a son of the lay priest Soya, it appears that Daishin died before the eighth month of 1279. He is thought to have been a different person from Daishin-bō, who lived in the Fuji area and later betrayed Nichiren.
