 Gelug maintains that “objects of knowledge” (shes bya) are the basis for dividing the two truths (Tsongkhapa  1984b:176).[4]  This means that the two truths relate to “two objects of knowledge,” the idea it takes from the statement of the Buddha from Discourse on Meeting of the Father and the Son (Pitāputrasamāgama  Sūtra)[5]  By object of knowledge Gelug means an object that is cognizable (blo'i yul du bya rung ba). It must be an object of cognitive processes in general ranging from those of ordinary sentient beings through to those of enlightened beings. This definition attempts to capture any thing knowable in the broadest possible sense. Since the Buddha maintains knowledge of the two truths to be necessary for awakening, the understanding of the two truths must constitute an exhaustive understanding of all objects of knowledge.
