The origin of depression

“The troubled person is led to believe that he can't help himself and must seek out a professional healer when confronted with distress related to everyday problems of living. His confidence in using the 'obvious' techniques he has customarily used in solving his problems is eroded because he accepts the view that emotional disturbances arise from forces beyond his grasp. He can't hope to understand himself through his own efforts, because his own notions are dismissed as shallow and insubstantial. By debasing the value of common sense, this subtle indoctrination inhibits him from using his own judgment in analyzing and solving his problems.”
