 The ontological identity between being conditioned and being impermanent does not imply identity in all and every respect. Insofar as their epistemic mode is concerned, conditioned and impermanent phenomena are distinct and contrasting. The concept impermanence always presents itself to the cognizing mind as momentary instants, but not as conditioned. Similarly, the concept being-conditioned always presents itself to its cognizing mind as constituted by manifold momentary instants, but not as moments. Thus it does not necessarily follow that the two truths are identical in every respect just because they share a common ontological identity. Where the modes of conceptual appearance are concerned, ultimate nature and conventional nature are distinct. The conceptual mode of appearance of ultimate truth is nondeceptive and consistent with its mode of existence, while that of conceptual mode of conventional truth is deceptive and inconsistent with its mode of existence.
