Bon is Tibet’s oldest spiritual tradition. It includes teachings and practices applicable to all parts of life, including our relationship with the elemental qualities of nature; our ethical and moral behavior; the development of love, compassion, joy and equanimity; and Bon’s highest teachings of the “Great Perfection,” dzogchen.
According to the traditional Bon account of its origins, many thousands of years before the birth of the Buddha Shakyamuni, the Buddha Tonpa Shenrab Miwoche came to this world and expounded his teachings in the land of Olmo Lungring. Ol symbolizes the unborn, mo the undiminishing, lung the prophetic words of Tonpa Shenrab, and ring his everlasting compassion. Some modern scholars have identified Olmo Lungring with Zhang Zhung, the country surrounding Mount Kailash in western Tibet and the cradle of Tibetan civilization.
Tonpa Shenrab is said to have taught Bon in three successive cycles of teachings. First he taught the “Nine Ways of Bon”; then he taught the “Four Bon Portals and the Fifth, the Treasury”; and finally he revealed the “Outer, Inner and Secret Precepts.” In the final cycle of teachings the outer cycle is the path of renunciation, or sutric teachings; the inner cycle is the path of transformation, or tantric teachings; and the secret cycle is the path of self-liberation, or dzogchen teachings. This division into sutra, tantra and dzogchen is also found in the Nyingma school of Tibetan Buddhism.
Followers of Bon receive oral teachings and transmissions from teachers in a lineage unbroken from ancient times until the present day. In addition, most of the scriptural texts also have been preserved.
