Tantrayana (Skt. tantrayāna; Tib. ཐེག་པ་རྒྱུད་, tekpa gyü, Wyl. theg pa rgyud), otherwise known as Mantrayana or the Vajrayana. It is the ‘Fruitional’ or ‘Resultant Vehicle’, because the path is no longer based on establishing the cause, but identifying directly with the fruition. Tantra begins with the view that the final attainment or result has been within the mind from the very beginning, but has been obscured by ignorance and adventitious defilements. Both sutra and tantra share the same ultimate goal of enlightenment. The greatest difference between them lies in the methods employed.
