Tibet's main religion is Buddhism. Their traditions make it a place of interest to many people. The local monks are sometimes said to have special, superhuman abilities. The writings of Tibetan monks are sometimes shared with outsiders, and are known for their insight. The "Tibetan Book of the Dead" contains rituals for the dead and dying, somewhat similar to the Catholic last rites. Some Tibetans practice a religion called Bon. People who study Bon disagree where Bon came from, how old it is, and if it can be called a kind of Buddhism. The religious leader of Tibet's Buddhists is called the Dalai Lama. He was forced to leave the country when the Chinese Army took over. The Dalai Lama presently lives in exile in India, but often visits other countries. Many monks and other religious people also were forced to leave the country, and many of them started Buddhist and Bon centers in cities around the world.
