AtÄ«Åa
AtÄ«Åa (born 982ādied 1054, Nyethang, Tibet [now Nyetang, China]) was an Indian Buddhist reformer whose teachings formed the basis of the Tibetan Bkaā-gdams-pa (āThose Bound by Commandā) sect of Buddhism, founded by his disciple āBrom-ston.
Traveling to Tibet in 1038 or 1042 from NÄlandÄ, a centre of Buddhist studies in India, AtÄ«Åa established monasteries there and wrote treatises emphasizing the three schools of Buddhism: the TheravÄda (exclusive belief in the Gautama Buddha), the MahÄyÄna (belief that Gautama Buddha is one of many buddhas), and the VajrayÄna (which emphasizes yoga). He taught that the three stages follow in succession and must be practiced in that order. He died at Nyethang Monastery, where his tomb still exists.
