Dalai Lama
The Dalai Lama is a lama of the Gelug or “Yellow Hat” school of Tibetan Buddism, founded by Tsongkhapa (1357–1419). The 14th and current Dalai Lama is Tenzin Gyatso, recognized since 1950.
The Dalai Lama is traditionally thought to be the successor in a line of Tulkus who are considered to be metaphorical manifestations of Avalokitesvara. The name is a combination of the Mongolic word dalai meaning “ocean” and the Tibetan word བླ་མ་ (bla-ma) meaning “guru, teacher, mentor”. The Tibetan word “lama” corresponds to the better known Sanskrit word “guru”
For certain periods between the 17th century and 1962, the Gelug school managed the Tibetan government, which administered portions of Tibet from Lhasa
