(Tib., Sa-skya). One of the four main schools of Tibetan Buddhism.taking its name from its original monastic centre at Sakya (‘grey earth’) in southern Tibet. It was founded in 1073 by members of the Khon family who, though laymen, have traditionally acted as the heads of the school. While the Sakya school preserves the lam-dre (‘path and result’) teachings transmitted by Virūpa, it is is also renowned for a keen interest in Buddhist logic (pramāṇa) and epistemology which derives from the seminal work of Sakya Paṇḍita (1182–1251). The Sakya school was politically influential during the 13th and 14th centuries, especially through their dealings with the neighbouring Mongols (see Mongolia). The head of the school is known as the Sakya Trindzin or ‘throne holder’ (Tib., Sa skya khri 'dzin), and the present head now resides in India at Sakya College, after fleeing Tibet following the Chinese invasion.
