Every atom of man's body expresses his past, present and future. The reason is that, in the first place, every impulse creates its vibrations and takes a particular direction of activity. This influences the heart, whence the blood is circulated through the whole body. In this way the thought is, so to speak, written on man's face. Man's continual agitation in regard to others, his satisfaction or dissatisfaction, his love or hatred, all show in his appearance. Everyone can know it more or less, but the seer can read more correctly. It is difficult to tell definitely the marks of a person's thoughts and feelings that are shown in his appearance; nevertheless, partly by intuition and partly by experience, man reads them. There are some in whom self-control is developed, who are capable of hiding their thoughts and emotions, and yet it is impossible to feel deeply and to hide one's feelings from the eyes of others.
