Nearly all Tibetans follow Tibetan Buddhism, known as Lamaism, with the exception of approximately 2,000 followers of Islam and 600 of Catholicism. Tibetan Buddhism was greatly influenced by Indian Buddhism in its early time, but after years of evolution, Tibetan Buddhism has developed its own distinctive qualities and practices. A well-known example is the belief that there is a Living Buddha, who is the reincarnation of the first, a belief alien to Chinese Buddhism.
It is freezing cold in most time of the year. Most tourists come to visit Tibet only in the warmest seasons, June, July, August and early September.
