"Madhyamaka and Yogācāra are the two main philosophical trajectories associated with the Mahāyāna stream of Buddhist thought. According to Tibetan doxographical literature, Madhyamaka represents the philosophically definitive expression of Buddhist doctrine. Stemming from the second-century writings of Nāgārjuna, Madhyamaka developed in the form of commentaries on his works. This style of development is characteristic of the basically scholastic character of the Indian philosophical tradition. The commentaries elaborated not only varying interpretations of Nāgārjuna’s philosophy but also different understandings of the philosophical tools that are appropriate to its advancement." - ~C4Chaos from Bookmarklet
