Seizan (西山) is the name of the branch of Jōdo-shū Pure Land Buddhism that was founded by Hōnen's disciple, Shōkū (1177-1247). As a branch of Jōdo, the central practice is devotion to Amida Buddha, and recitation of the nembutsu. Shōkū coined the practice, where one devotes himself to intense study of Buddhist literature, and then recites the nembutsu with deep, sincere faith.
