The Senchaku Hongan Nembutsushū(選択本願念仏集), abbreviated to Senchakushū, is the magnum opus of Hōnen, founder of the Jōdo shū school of Japanese Pure Land Buddhism. The title means "Passages on the Selection of the Nembutsu in the Original Vow" and draws upon past Pure Land Buddhist sources, sutras and especially from the writings of Chinese Pure Land Buddhist Shan-tao to bolster Hōnen's doctrine of relying upon the sole recitation of Amitabha Buddha's name for rebirth in the Pure Land. Hōnen also asserts for the first time that he is establishing a new school of Buddhism.
