(or lamaism). A form of Mahayana Buddhism as practised in Tibet and Mongolia. Introduced into Tibet in the 7th Century AD, it is characterised by a complex symbolic literature and monastic discipline, with surviving features of Bön shamanism. Buddhist elements are explored in their esoteric significance, hence the array of deities, mandalas, etc. The guru is of prime importance; some are held to be reincarnations of previous lamas (called tulkus). Until the Chinese invasion of Tibet in 1959, the Dalai Lama was both temporal and spiritual head of the state. See also Panchen Lama.

Tibetan Buddhism has four main schools (remaining out of eight):
