Bon, also spelled Bön (Tibetan: བོན་, Wylie: bon, Lhasa dialect: [pʰø̃̀]), is the native Tibetan folk religion. It is characterized by Animism, Shamanism and ancestor worship. Mystic rituals, spells, sacrifices for gods and spirits, and spirit manipulation are common elements in the native Tibetan traditions. It was the major religion in large parts of Tibet and some other parts of China until the 7th century. Many current traditions of Tibetan Buddhism were influenced by the native Bon religion.
According to traditional Bon beliefs and legends, the Bon religion predates the arrival of Buddhism in Tibet. According to the scholar and Buddhist master Chogyal Namkhai Norbu Rinpoche, there is clear manuscript evidence confirming the existence of fully articulated Bon doctrine and practice prior to the forcible annexation of the Bon kingdom of Zhangzhung in the 8th century CE by Tibetan king Trisong Deutsung: "It is very clearly stated in the ancient lineage-manuscripts of Bon, known as Srid-rGyud, during the reign of the Buddhist King Trisong Deutsen, that the tradition of Bon and its founder both first started [centuries earlier] in Zhangzhung."
