Modesty must be further guarded in our very movements and gestures and gait.  For the condition of the mind is often seen in the attitude of the body.  For this reason the hidden man of our heart (our inner self) is considered to be either frivolous, boastful, or, on the other hand, steady, firm, pure, and dependable. Thus the movement of the body is a sort of voice of the soul.”
-Saint Ambrose of Milan (Duties of the Clergy)
