The last and bitterest of the combats was fought in Miyako in 1536, when the soldier-monks of Hiei in alliance with the Ikkō fanatics attacked the Nichirenites and burnt down twenty-one of their great temples in the capital and drove them out of the city. Shouts of “Namu Myōhō Renge Kyō,” the slogan of the Nichirenites, vied with “Namu Amida Butsu,” the prayer of the Ikkō men; many died on either side, each believing that the fight was fought for the glory of Buddha and that death secured his birth in paradise.
