the eyes are the windows to the soul

The eyes are the windows to the soul means that if you look into someones eyes you can read them better and sometimes literally see through to their soul where you can feel or sense the kind of person they are. It comes from Hiram Powers who was an American sculptor and said The eye is the window of the soul, the mouth the door. The intellect, the will, are seen in the eye; the emotions, sensibilities, and affections, in the mouth. The animals look for mans intentions right into his eyes. Even a rat, when you hunt him and bring him to bay, looks you in the eye.
