AstralCody is correct. You must believe you can do it. That is probably where I go wrong. One time I could not go through the wall. Another time I said I can do this and I was able to go through it. When you are out of your body next time, say I am with my brother now. I know I can see him right now. Keep saying it until it happens. Just believe it will happen and it will happen. That is what I have to do.
