The Early Sessions, Book 9

"Now when anything is wrong with your body, it is trying to tell you something. And when you understand what it is trying to say, and if you make an effort to do what is needed, the symptoms are no longer needed as a method of communication. The body is trying to tell you that you have a problem, and because you did not cope with it, and denied it mentally, it is physically materialized in symbolic body language."
