Cosmic consciousness is real.  Mysticism is false.  A rock is a rock, and a tree is a tree.  Consciousness, cosmic or otherwise, is all in the brain.  There is no spirituality because there are no spirits, no souls, no ghosts, and no Gods.  That is why gurus become corrupt, cults become dangerous, and disciples become foolish.   If the whole universe is God, soul, and identity, then what is death?
