Dalai Lama himself says; "The Dalai Lama is just a temporal leader of Tibet."
The Dalai Lama is a reincarnated lama (spiritual leader - teacher - guide) of the Gelug or "Yellow Hat" school of Tibetan Buddhism, founded by Tsongkhapa (1357-1419). The name is a combination of the Mongolic word dalai meaning "ocean" and Tibetan word lama meaning "guru", "teacher" or "mentor". The Dalai Lama is traditionally thought to be the successor in a line of tulkus who are considered to be metaphorical manifestations of Avalokitesvara.
Names of popular Dalai Lama include Gendun Drup, Gendun Gyatso, Sonam Gyatso, Yonten Gyatso, Ngawang Lobsang Gyatso, Tsangyang Gyatso, Kelzang Gyatso, Jamphel Gyatso, Lungtok Gyatso, Tsultrim Gyatso, Khendrup Gyatso, Trinley Gyatso, Thubten Gyatso and Tenzin Gyatso.
