There are many things in the patient that one can perceive not only from his inclinations but by noticing his face and features; for in this way one reads more than by any other method. The features tell his general characteristics, and therefore a person knows the weakness that may have been the origin of his complaint, and the general expression shows the thought behind it. Since mind is the cause of all causes, the healer gets at the root of the complaint as soon as he touches the mind of the patient. How true is the saying, man's face is the mirror of his heart.
