In the Battle of Vatapi, the Pallava ruler Narsimhavarman I defeated and killed Pulakesin II and captured the Chalukyan capital, Badami in 642 AD. Thus, he assumed the title of ‘Vatapikonda’ (Conqueror of Vatapi).
Nagarjuna was also termed as the Indian Einstein. He proposed the Theory of Relativity in his time in the form of a Sutra which is also called as the Prajna Parimata Sutra. He was a great patron of Mahayana doctrine.
