The gZi-brjid, or “The Glorious,” is a fundamental text of the Tibetan Bon religion, said to have been spiritually transmitted to Londen Nyingpo, who recorded the revelation, in the fourteenth century. This twelvevolume text contains a biography and the teachings of Tonpa Shenrab Miwoche, the founder of Bon. Bon originally referred to practices associated with ancient Tibetan folk traditions. Over the centuries, Bon gradually developed a religious institutional structure, and in many respects it has merged with Tibet's official religion, Buddhism. Bon is considered the oldest extant religious tradition in Tibet. Bon adherents refer to themselves as Bonpos.
