Sakya

Sakya Pandita (1182–1251) was a 13th-century head of the Sakya school and ruler of Tibet. He was also one of the most important Buddhist philosophers in the Tibetan tradition, writing works on logic and epistemology and promoting Dharmakirti 's Pramanavarttika (Commentary on Valid Cognition) as central to the scholastic study. Sakya Pandita's 'Treasury of Logic on Valid Cognition' (Tshad ma rigs pa'i gter) set forth the classic Sakya epistemic anti-realist position, arguing that concepts such as universals are not known through valid cognition and hence are not real objects of knowledge. Sakya Pandita was also critical of theories of sudden awakening, which were held by some teachers of the "Chinese Great Perfection" in Tibet.

Later Sakyas such as Gorampa (1429–1489) and Sakya Chokden (1428–1507) would develop and defend Sakya anti-realism, and they are seen as the major interpreters and critics of Sakya Pandita's philosophy. Sakya Chokden also critiqued Tsongkhapa's interpretation of Madhyamaka and Dolpopa's Shentong. In his Definite ascertainment of the middle way, Chokden criticized Tsongkhapa's view as being too logo-centric and still caught up in conceptualization about the ultimate reality which is beyond language. Sakya Chokden's philosophy attempted to reconcile the views of the Yogacara and Madhyamaka, seeing them both as valid and complementary perspectives on ultimate truth. Madhyamaka is seen by Chokden as removing the fault of taking the unreal as being real, and Yogacara removes the fault of the denial of Reality. Likewise, the Shentong and Rangtong views are seen as complementary by Sakya Chokden; Rangtong negation is effective in cutting through all clinging to wrong views and conceptual rectification, while Shentong is more amenable for describing and enhancing meditative experience and realization. Therefore, for Sakya Chokden, the same realization of ultimate reality can be accessed and described in two different but compatible ways.
