Sangpu Neutok is an important monastery in central Tibet, just south of Lhasa, that was founded in 1072 by Ngok Lekpai Sherab, a disciple of Atiśa, and developed by his nephew, Ngok Lotsāwa Loden Sherab. Originally a Kadam monastery with two colleges, it evolved into a monastery that includes both Sakya and Geluk traditions. At its peak in the 11th to 14th centuries, it was one of the most highly esteemed centers for monastic education and the study of Buddhist philosophy in all of the Tibetan plateau. Many influential philosophers of the time studied there.
