Right now, the only things that are in your experience are your body, your mind, and your emotions.You know them to some extent, and you can infer that if these three things have to happen the way they are happening, there must be an energy that makes them happen. So these are the only four realities in your life: body, mind, emotion, and energy.
Whatever you wish to do with yourself, it must be on these four levels. Whatever you wish to do you can only do it with your body, your mind, your emotions or your energy.
