Categories of vehicle
The buddhist teachings are often classified according to yanas, most commonly into the two yanas, the 'basic' or 'individual' vehicle (Skt. hinayana) and the 'greater' or 'universal' vehicle (Skt. mahayana), or the three yanas. The Nyingma tradition also classifies the teachings into the nine yanas.
