Difficulty getting out of your body is a common problem for some new witches. When I was a kid I felt like my soul was deeply meshed with my body from the tip of my toes to my forehead. I couldn’t even imagine them being separate. First I had to change that view before I could ever have an out of body experience.
I think one of my better first experiences was in one of Taylor Ellwood’s classes. He had us breath out our subtle bodies. All of us were in this darkened room. We were sitting or even on our hands and knees. Taking in deep breaths. And eventually we started to push with our breath out a etheric double of ourselves. Out in front of us. Not far, just even a foot in front of us, and then inhale it back in. In and out.
