The Buddhist tradition especially associated with devotion to Amitabha Buddha is Pure Land Buddhism.
Pure Land teachings focus on Amitabha, also called Amitayus in some contexts, and his realm known as the Pure Land. Practitioners commonly express faith in Amitabha and recite his name, with the aspiration of being reborn in the Pure Land, where conditions are considered favorable for attaining Buddhahood.
Pure Land traditions developed from Mahayana scriptures such as the Larger Sukhavativyuha Sutra and the Smaller Sukhavativyuha Sutra. They became especially influential in China, Korea, Japan, and Vietnam. In Japan, Jodo Shu and Jodo Shinshu are major Pure Land schools.
Pure Land Buddhism is not simply a belief in a heavenly afterlife. Its teachings connect devotion, ethical conduct, faith, and awakening. It also differs from Zen, although many East Asian Buddhists have historically practiced elements of both traditions.
