Control of your feeling is all important to a full and happy life. Never entertain an undesirable feeling, nor think sympathetically about wrong in any shape or form. Do not dwell on the imperfection of yourself or others. To do so is to impress the subconscious with these limitations. What you do not want done unto you, do not feel that it is done unto you or another. This is the law of a full and happy life. (Neville Goddard, Feeling is the Secret)
