Two yanas

Two yanas (Tib. ཐེག་པ་གཉིས, tekpa nyi; Wyl. theg pa gnyis) — from the general perspective of the Vajrayana, the two yanas refer to:

• the Sutrayana, which is also known as the Causal Vehicle, and
• the Tantrayana, which is also known as the Resultant Vehicle.

Each yana or vehicle can, in turn, be sub-divided into more vehicles.
