Bon or Bön (Tibetan: བོན་, Wylie: bon, Lhasa dialect IPA: [pʰø̃̀]) is a Tibetan religion, which self-identifies as being distinct from Tibetan Buddhism, although it shares the same overall teachings and terminology. It arose in the eleventh century and established its scriptures mainly from termas and visions by tertöns such as Loden Nyingpo. Though Bon terma contain myths of Bon existing before the introduction of Buddhism in Tibet, "in truth the 'old religion' was a new religion."
As Bon only arose in the eleventh century through the work of tertons, Sam van Schaik states it is improper to refer to the pre-Buddhist religion of Tibet as Bon:
Though some people call the old pre-Buddhist religion of Tibet ‘Bon’, it is unlikely that before Buddhism the Tibetans had a clear sense of practising a religion as such, or a specific name for these practices. In fact, the Bonpo religion only started to take shape alongside the revival of Buddhism in the eleventh century. And when the scriptures of the Bonpo started to appear in Tibet, it was mainly through the work of tertons.
Three Bon scriptures—mdo 'dus, gzer mig, and gzi brjid—relate the mythos of Tonpa Shenrab Miwoche. The Bonpos regard the first two as gter ma rediscovered around the tenth and eleventh centuries and the last as nyan brgyud (oral transmission) dictated by Loden Nyingpo, who lived in the fourteenth century. In the fourteenth century, Loden Nyingpo revealed a terma known as The Brilliance (Wylie: gzi brjid), which contained the story of Tonpa Shenrab. He was not the first Bonpo tertön, but his terma became one of the definitive scriptures of Bon religion. It states that Shenrab established the Bon religion while searching for a horse stolen by a demon. Tradition also tells that he was born in the land of Tagzig Olmo Lung Ring (considered an axis mundi) which is traditionally identified as Mount Yung-drung Gu-tzeg (“Edifice of Nine Sauwastikas”), possibly Mount Kailash, in western Tibet. Due to the sacredness of Tagzig Olmo Lungting and Mount Kailash, the Bonpo regard both the swastika and the number nine as auspicious and as of great significance.
