Hi 3cat, yes, visualize energy moving from the lower sides of your brain, up thru the middle, then holding it there in the top front half of your brain. I know this sounds nutty, but it seems to work for me. Astral projection exercises involve moving energy around your body. For example visualize energy moving from your knee to your toes and back again. Repeat this over and over, and very quickly you will start to feel sensations that are hard to discribe. Everybody can do these exercises and feel it happening with little or no practice. Body awareness.
