I Want to Master Astral Projection.

Does anyone have some knowledge on relief for anxiety. I think I have chakra/life energy imbalance in my gut. Is a park suffice? Does it have to be quiet? I'm homeless & I'm regularly harrassed and losing places to go. I heard of yoga & meditation but have yet to do it. I almost did astral 1 time. I was warned about it. Maybe cause I'm prone to negativity? I heard about vibrations from near death dot com.
