 This drove Dharmakīrti away, and resolving to vanquish all non-Buddhist heretics he took the robes of the Buddhist order instead.According to legend, Kumārila went to study Buddhism at Nalanda (the largest 4th-century university in the world), with the aim of refuting Buddhist doctrine in favour of Vedic religion.He was expelled from the university when he protested against his teacher (Dharmakirti) ridiculing the Vedic rituals.
