This is one topic I'm really into at the moment and possibly the one which will one day really bring the truth to us when we die. I'm currently on an astral website, and you know what, the people on there gave the best answer ever to astral projection." Try it"! they give courses on there as how to leave your physical body. I've heard alarming accounts from people I know who've had OBE's and it's amazing. Even blind and deaf people on how they can hear and see in the astral plane. It goes to prove that consciousness really IS a great mystery. I think of us as the "ghost" as such in a physical body.
