Postmodern doesn't imply that we have arrived at some new enlightenment or some new way of looking at ourselves and our world say, like the Na'vi, in James Cameron’s film, Avatar.
Postmodern only means that we are moving away from modernity, that is, moving away from the dominance of the subject in which human subjectivity has become the measure of all things. Where this movement is exactly taking us, minus the subject who controls the picture of reality we daily see, is perhaps anybody’s guess. But if you’ve guessed this postmodern movement is more like an escape, you might be right.
All up an down the postmodern escape route are improvised, idealized (and ideological) communities that sense, at some level, what subjectivity really means and entails. For one thing, they are aware of its commanding power that rides under the banner of Descartes’ “I think therefore I am” (or if you prefer, “I am therefore I think”) which, at bottom, is an attempt to make the subject the authority who then goes about ruthlessly organizing the outer world in the image of itself, that is, by way of its reasons. (We should not forget who was the celebrated goddess of the French Revolution during its reign of terror, it was Reason!)
Turning this light towards Buddhism, opinions may differ about what the Buddha actually taught, nevertheless, Buddhism’s place sits firmly in the makeshift, evolving postmodern world that is escaping from imperious subjectivity.
Buddhism is a threat to modernity. Its “no-self” or “nonself” doctrine is a serious blow to the hegemony of the psychophysical being, in particular, the subjective aggregates of feeling, perception, inclination, and sensory consciousness. In a nutshell, according to Buddhism these aggregates are not our real self but neither is the self to be found in the objective world, this being the first aggregate of material shape (rupa).
Where the real power of Buddhism lies is in its ability to dethrone both the subject and object thus revealing them to be completely empty—empty in the sense of lacking true or absolute reality. This is especially evinced when, during meditation, a practitioner enters in direct communion with pure Mind. In this meditation, both subject and object are discovered to be Mind configurations but nothing apart from it.
As a consequence of this, not only does our subjective world suddenly become illusory along with the objective world which turns into a phantasmagoria, but try as we might, we can find no self in either the subject or object—no real reference point. Our self, as that which is always itself (never other), remains ever transcendent and certainly beyond the scope and range of subjective apprehension and its reasoning power.
