Compendium of Valid Cognition
Compendium of Logic (Skt. Pramāṇa-samuccaya; Wyl. tshad ma kun las btus pa) by Dignaga — one of the greatest works on Buddhist logic, in which Dignaga gave a new definition of "perception": a knowledge that is free from all conceptual constructions, including name and class concepts.
Dignaga's tradition is further developed in the 7th century by Dharmakirti.
