When you open to who you really are at the core of your being, you find there that you are energy and consciousness originating beyond the body, expressing itself through your ego body.
The mind, emotions and body form a triangle of energies that the ego senses as itself. This is the ego body. When these three aspects of self are connected and relatively balanced, they form a container for the larger self, that many call the soul, to pour through for loving purpose.
Imagine you are at the center of this triangle. To see it in your mind's eye, draw a triangle with a point in the middle. At the first point of the triangle, label it "physical body". At the second point, label it "Emotion". And at the third point, put the word "Mind". Then at the point in the center, write the word "soul".
Think of times when you have felt centered and balanced. Note that you will have centered your sense of self at this point in the middle of this energetic triangle. Here, you are the observer-feeler. Not a disembodied head or heart. Not a dissociated body. But from this point, you are using all three aspects of ego self, as the appendages of soul that they are in this physical plane. You feel your bodily sensations, your thoughts and ideas, and your emotional responses to these ideas and observations. You are using your heart to navigate the direction in which your soul longs to move. You are using your head to help you get there. And you are using your body for the expression of soul it is intended to be.
This state of consciousness is where you want to be to feel centered and balanced, and a vessel for your soul awareness. This is the ultimate state for mind-body awareness.
