Dharmakirti

Dharmakirti, who flourished around 600 to 670 CE, was an influential Indian Buddhist philosopher who worked at Nalanda, one of the key scholars of epistemology, known as pramana, in Buddhist philosophy, and associated with the Yogacara and Sautrantika schools; he was also one of the primary theorists of Buddhist atomism. His works influenced scholars of the Mimamsa, Nyaya and Shaivism schools of Hindu philosophy as well as scholars of Jainism, and his Pramanavarttika, his largest and most important work, was very influential in India and Tibet as a central text on pramana, valid knowledge instruments, widely commented on by Indian and Tibetan scholars, with his texts remaining part of studies in Tibetan Buddhist monasteries.
