why stop there? only the thinking mind is proven - the body could be hallucination
or a model created by the brain
..but why stop there? there is no single place in the brain where a 'self' lives: what we call the mind is a stream of momentary activity - images, voices, impulses, memories, feelings - all stitched together by habit. so even the 'mind' is just label for a set of constantly shifting processes. it’s not a real entity
in the end, all there really is is awareness
that is to say: matter is a story told within awareness, not the other way around ..perhaps God is awareness itself
