When I attempt to astral project, I start by meditating. I try to focus my awareness a few feet above me, looking down. After 30 minutes of meditation and trying to focus my awareness outside of my body, still nothing happens. (I am deeply physically relaxed by the way). What else should I do? Is it necessary to develop astral sight (or see through my eyelids) before I leave my body? Does the sense of vision come before I leave my body (while I'm meditating) and do I have to wait for it, or do I try to leave my body and expect it to come when I leave?
Thanks.
