To accept the notion of "becoming" as central involves both a tearing down and a freeing up to build. On the one hand, we have to watch certain notions that we like very much, formerly steady and eternal, sink and crumble into steaming, swirling murk. Some of these are pretty important navigational maps.
But then so on the other hand, as those maps disappear, the world behind them eventually (after some blind scrabbling around) starts to come into focus on its own terms. Understanding ourselves and the world as unfolding in a constant process of becoming is to accept mystery, to accept even that we are irreducible mysteries to ourselves. In doing this, we allow ourselves to be surprised by experience in its own shocking clarity. Without mediating concepts, we just sort of look with our eyes, hear with our ears, taste with our mouths, smell with the ol' factory, feel with our feet and our feelings. In this way, truth isn't a thing imparted, but instead understanding is expanded through the experience of constantly running up against mystery, paradox, and allowing this to change and transform things on both sides.
Live performance is uniquely equipped for this sort of collision. The physical world is the world of becoming. The mortal body is an argument against universal intellectual truth. Using illusion, moving, breathing, and changing forms, the performer can open up gaps in what we hold as reality, revealing the fundamental mystery behind. Perceptual and relational shifts can occur.
The first step here is donning the corpse body--becoming the corruptible, mouldering objects that we are, becoming mysterious things among other things. Paradoxically, this objectification is an acceptance of mortality, an opening, an embrace of swarming mystery. From this standpoint, transformation is possible, for we are no longer in the realm of eternal forms. We can begin to build and destroy and play and illuminate in a world where discovery and surprise are possible, and we can open up this possibility for an audience.
