You can neither be aware nor unaware of awareness. To be aware of awareness, as it is happening, you need to shift the angle of incidence to be almost identical with the grain. That never happens, it is a complete misuse of what ought to be a useful instrument for living. But strangely the potential is always there and there could be no everyday awareness without that tiny displacement, that excess over itself, that curious artifact of embodied life, the knowing you know the knowing you know.
