If you are looking for something that will totally open your eyes to experiencing the multi-dimensionality of life, Astral Projection is what you need. And to learn to do it, this book is a must! I've read a ton of literature on Astral Projection and was getting exhausted by all of the useless theories that seems to surround subjects like this. When I came across the online courses, I was pleasantly surprised by how simple it was explained. With practice, I was able to finally experience it for myself.If you want to project, all you have to do is follow the authors directions to the t. It's as simple as that!
