The Power of Now
I is the true self living in the present. That what we truly are.
The Mind is what we may mistakenly identify with. He is the thinker, origin of thoughts and emotions. Emotion is the body reaction to your mind. The Mind is just a tool that the true self can use for day-to-day life, nothing more. Be the witnessing consciousness of the thinker.
The Pain-body is an invisible entity, a negative energy field that accumulates past pain. It can be dormant or active. Any thought, or experience can activate it. As any entity, he can only survive in you by making you believe it is you. He will feed through your negative energy (pain, hatred). That is why some people behaves in order to get more pain. He is afraid of the light of consciousness. He is the shadow cast by the ego. Shine the pain-body with the light of consciousnesses to dissolve it. Don't be afraid of facing the pain-body. This is an illusion. If you realize it, it will disappear. Be the witness of the pain-body. You attained an higher dimension of consciousness called presence.
