our participation in the world actually begins at the quantum level. for all practical purposes, this is where mind and matter meet. 
...we can consciously return to the quantum level, which expands our participation infinitely compared with what we can do once creation has hardened into place. not only is creation softer, so to speak, but mind and matter haven't separated yet. when they do, a rock won't instantly become a rock while a thought goes another way and instantly becomes a thought.
mind and matter first emerge exactly alike, as invisible ripples in the quantum field.
