The defining characteristic of relative truth is that it is an object of consciousness that in its fundamental nature is itself essentially empty of veridical being. The defining characteristic of absolute truth is that it is an object of authentic, sublime wisdom that in its fundamental nature is itself essentially not empty of veridical being.
Because the relative does not exist in fact, it is intrinsically empty, and appears to consciousness, but not to sublime wisdom. Because the absolute exists in fact, it is not intrinsically empty, and appears to sublime wisdom, but never to consciousness.
Thus, to those who are immature, according to their own dispositions, only inauthentic characteristics appear to their consciousness, but not the authentic suchness. To the sublime wisdom of the Bodhisattvas, according to their dispositions, only the authentic appears, but not what is inauthentic.
