Current Western designation of Tibetan-type Buddhism, which was not only widespread in Tibet but also in the Himalayan and adjoining countries, as well as in Mongolia and partially in China. Its name comes from the Dalai Lama, supreme spiritual leader of this stream, which is a variation of Mahayana Buddhism. Its particularity consists in the fusion of the ancient monastic rules of the Sarvastivada with the ritual methods of the Vajrayana.
