Bon is Tibet's pre-Buddhist indigenous spiritual tradition — older than the Buddhism that largely supplanted it in the 7th century CE and containing shamanic practices, cosmological systems and meditative techniques that are distinct from but parallel to those of Tibetan Buddhism. Bon practitioners claim that their tradition originated with the historical figure Tonpa Shenrab Miwoche in the land of Olmo Lungring (possibly ancient Persia or Central Asia) some 18,000 years ago.
Modern Bon is a sophisticated living tradition with its own monasteries, texts, meditation practices and lineages — recognising five types of Bon practice from folk shamanism through ethical teaching to the highest meditative practices. Its highest teaching — Dzogchen (Great Perfection) — is structurally identical to the Dzogchen teachings of the Nyingma school of Tibetan Buddhism, raising profound questions about the direction of influence.
