After much experience in astrally projecting I got the feel of how to project a gross or subtle astral body. I was primarily trying to project the most material astral body possible.
    One night I had friends camping out. I projected a gross astral body to them. They thought I was there in the flesh, but I made them aware that I had no reflection. They panicked and one of them threw a flashlight at me. It went right through me, and I didn't even feel it.
    These people remained distant from me from that time on, and, I developed an infamous reputation. But, my parents used to say, "Fear is respect".
