" It was as if personality itself had a “face.” This nonphysical “face of personality” seemed to be the real key to personality change. If it remained scarred, distorted, “ugly,” or inferior, the person himself acted out this role in his behavior regardless of the changes in physical appearance. If this “face of personality” could be reconstructed, if old emotional scars could be removed, then the person himself changed, even without facial plastic surgery. Once I began to explore this area, I found more and more phenomena that confirmed the fact that the “self-image,” the individual’s mental and spiritual concept or “picture” of himself, was the real key to personality and behavior. More about this in the first chapter. "
