So the pain-body doesn't want you to observe it directly and see it for what it is. The moment you observe it, feel its energy field within you, and take your attention into it, the identification is broken. A higher dimension of consciousness has come in. I call it presence. You are now the witness or the watcher of the pain-body. This means that it cannot use you anymore by pretending to be you, and it can no longer replenish itself through you. You have found your own innermost strength. You have accessed the power of Now.
