By saying a prayer (Shomyo nenbutsu) to the Buddha (Namu Amida Butsu, Namo Amida Butsu by Hongan-ji School), practitioners can believe in the mercy of Amida Nyorai (hereinafter called "Nyorai"), and trust in Tariki (Buddha's power), which makes everyone, including the bad, go to Jodo (Pure Land) after death and become Buddha.
念仏（南無阿弥陀仏、なむあみだぶつ、なもあみだぶつ（本願寺派））を称えること（称名念仏）を通して、阿弥陀如来（以降「如来」）の慈悲を信知せしめられ、悪人を含む全ての人が浄土へ往生し成仏するという絶対他力への信順を往生成仏の正因とする。
