 A great deal has been written on the difference between Prāsaṅgika and Svātantrika (Dreyfus and McClintock 2003). Historically, the Gelukpa's Yogācāra-svātantrika-madhyamaka is another name for the mainstream philosophical school that developed in Tibet, based primarily on the teaching of Śāntarakṣita and his student Kamalaśīla (both fl. end of the eight century), the most influential of all the Indian paṇḍitas involved in the dissemination of Buddhist ideas to Tibet. Later Gelukpa scholastics, basing themselves on the mature works of Tsongkhapa, are unequivocal that Yogācāra-svātantrika-madhyamaka, like the Yogācāra philosophy of Asaṅga, is wrong, and has only heuristic value. At the same time, they tacitly acknowledge its centrality by taking this “wrong” philosophy as the foundation of their studies.
