THE TRADITIONS OF THE GREAT CHARIOTEERS NAGARJUNA AND ASANGA, who comment upon the meaning of these two kinds of teaching, are immaculately pure. Their paths moreover are not biased in the sense of emphasizing only their respective point of view. They simply elucidate the profound and vast aspects of the Buddha's teaching. Their views complement each other. This merging of the two approaches, whereby space like profundity and ocean like vastness are not sundered, was rare even in India, let alone Tibet. For it was in India, at a time when the systems of the great charioteers Nagarjuiia and Asaiiga were kept separate, that the master Shantarakshita united the two approaches into a single scriptural tradition greater than any other-for indeed the profound and vast aspects are equally indispensable to the Mahayana.
