  Bhāvaviveka, who was also known as Bhavya and Bhāviveka, was probably active in the middle part of the sixth century. His commentary on MMK, entitled Prajñāpradīpa (Lamp of Wisdom), now extant only in Chinese and Tibetan translations, contains not only his interpretation of Nāgārjuna’s thoughts but also critiques of Buddhapālita’s approach to Madhyamaka, about which more will be said below, and critiques of the Buddhist abhidharma tradition. Prajñāpradīpa also incorporates critiques of such non-Buddhist schools as Sāṃkhya, Vaiśeṣika and the Jains.
