Buddhism in Tibet

The Tibetan people believe in Buddhism, which spread into Tibet during the reign of Buto King Songtsan Gambo in the 7th century. It is an ancient strain of Tantric Indian Shamanism. It is called Lamaism and it believes strongly in reincarnation. Lama means "teacher" or "superior being". A lama must be a monk, but not all monks can become lamas. By the end of the 14th century, Tibetan Buddhism had had a variety of sects, which permeated Tibetan society.
