The name of the bodhisattva who established the Pure Land form of Buddhism. The power he gained from his merit as a bodhisattva enabled him to establish the Pure Land and now allows him to help others enter the Pure Land. The laity in particular can now enter the Pure Land with Amitabha's help, they do not have to get there on their own power. All they need do is to chant and believe the Amida Butsu.
