Sutrayana

Sūtrayāna, (Sanskrit) is the Indo-Tibetan three-fold classification of yanas. A yana is a Buddhist mode of practice that leads to the realization of emptiness. The three yanas of the Sutrayana are Sravakayana or Pratyekabuddhayana, Mahayana, and Vajrayana. The third yana, Vajrayana, comprises Tantrayana and Dzogchen.
