The Astral Pulse

I Discovered an amazing thing the other day... Usually, I project and it will never last more than 10 min... :/    For no reason I'd leave my astral body and wake up physically, or just start dreaming.  One reason for this i have heard before is because we run out of energy.  If we draw in energy when we're physically awake, I wondered if I could do it in the Astral.  When I first projected, I just imagined a waterfall type setup, except it poured energy instead of water.  I just stood underneith it for a few seconds until I felt satisfied, and I projected for a good three hours it seemed.  I had my friend try this and he had the same results!  Give it a try and see what you all think!!!
