On Knowing Reality: Tattvārtha Chapter of Asaṅga's Bodhisattvabhūmi

This is the first English translation with commentary of a crucial chapter of the Bodhisattvabhumi, composed in Sanskrit in the late fourth century by the philosopher-sage Asanga, founder of the Yogacara school of Mahayana Buddhism. The chapter is the core of Asanga's theoretical teachings: it deals with the central epistemological question of how to judge and validate knowledge, and how confusions about "reality" arise.
