Indian Buddhism was introduced into the ancient Tibet ( The Tubo Empire) in the 8th century AD and the esoteric Buddhist teachings and practice were gradually accepted by the Tibetan. Experiencing more than two hundred years clashes and blends with the local Bonism, Buddhism began to take its root and blossom in Tibet. The present-day Tibetan Buddhism is composed of schools of Prajna, Yogacara, and Esoteric Buddhism and, within the system, the Chan tradition of China proper ( Han-dominated areas) also plays an important role in shaping of the Tibetan Buddhism.
