Atiśa

Atīśa Dīpaṅkara Śrījñāna or Atīśa Dīpaṃkara Śrījñāna(; 982–1054) was a Bengali Buddhist religious leader and master from Bengal. He is generally associated with his work carried out at the Vikramashila monastery in Bihar. He was one of the major figures in the spread of 11th-century Mahayana and Vajrayana Buddhism in Asia and inspired Buddhist thought from Tibet to Sumatra. He is recognised as one of the greatest figures of medieval Buddhism. Atiśa's chief disciple, Dromtön, was the founder of the Kadam school, one of the New Translation schools of Tibetan Buddhism, later supplanted by the Gelug tradition in the 14th century which adopted its teachings and absorbed its monasteries.

In 2004, Atiśa was ranked 18th in the BBC's poll of the greatest Bengalis of all time. Provided by Wikipedia
