 Conventional truth is uncritically confirmed by conventionally reliable cognitive process, whereas ultimate truth is critically confirmed by ultimately reliable cognitive process. Hence, just as ultimate truth is inaccessible to the conventionally reliable cognitive process for its uncritical mode of engagement, so, too, is conventional truth inaccessible to ultimately reliable cognitive process for its critical mode of engagement. This is how, in Gelug’s view, the truths differ conceptually despite sharing a common ontological entity. In summarizing Gelug’s argument, Khedrub Jé writes: “The two truths are therefore of the same nature, but different conceptual identities. They have a single-nature relationship such that, if one did not exist, neither could the other, just like being conditioned and impermanent” (1992: 364).
