Sutrayana

Sūtrayāna, (Sanskrit) in the Indo-Tibetan three-fold classification of yanas, is the yana (mode of practice) that leads to the realization of emptiness. It consists of Hinayana and Mahayana. The other two yanas, according to this classification, are Tantrayana and Dzogchen, which together constitute Vajrayana.
