Peace of mind (anjin) comes about through contemplating the Primal Vow, that it is found within the calling voice, within the voice, within Namo Amida Butsu! This is "Namo" of Namo Amida Butsu. Namo is Namo Amida Butsu. What a truly indescribable taste this is! This is called the other-power faith.
