NagarjunaNāgārjuna (c. 150 – c. 250 CE) was an Indian Mahāyāna Buddhist thinker, scholar-saint and philosopher. He is widely considered one of the most important Buddhist philosophers. Jan Westerhoff considers him to be "one of the greatest thinkers in the history of Asian philosophy."
Nāgārjuna is widely considered to be the founder of the madhyamaka (centrism, middle-way) school of Buddhist philosophy and a defender of the Mahāyāna movement. His ''Mūlamadhyamakakārikā'' (Root Verses on Madhyamaka, MMK) is the most important text on the madhyamaka philosophy of emptiness. The MMK inspired a large number of commentaries in Sanskrit, Chinese, Tibetan, Korean and Japanese and continues to be studied today. Provided by Wikipedia
