Charles L. Whitfield said this quote

The observer self, a part of who we really are, is that part of us that is watching both our false self and our True Self. We might say that it even watches us when we watch. It is our Consciousness, it is the core experience of our Child Within. It thus cannot be watched—at least by anything or any being that we know of on this earth. It transcends our five senses, our co-dependent self and all other lower, though necessary parts, of us. Adult children may confuse their observer self with a kind of defense they may have used to avoid their Real Self and all of its feelings. One might call this defense “false observer self” since its awareness is clouded. It is unfocused as it “spaces” or “numbs out.” It denies and distorts our Child Within, and is often judgmental.
