The use of the superior recti muscles has also a definite effect upon the disposition. One of the pleasures of walking in a well-kept forest where the trees meet high overhead, is that the eyes are inevitably attracted upward to range among them, and there is a corresponding elevation of feeling. Bernard Shaw once said that it was impossible to enter a Gothic church without an elevation of the spirit, because the eyes were surely attracted upward by the height of the nave, and a corresponding uplift of feeling ensued. During a period of glumness it is apparently impossible to keep the eyes raised. People who are depressed and "cast down," as the expression is, invariably keep their eyes downward, and just as soon as a man "looks up and not down" there is a lifting of the depression. Even such apparently trivial muscular actions as this may influence the mind, and thus react upon the physical system generally. _Wrinkles_.--Many influences of the body on the mind group themselves in the muscles of expression around the eyes. Wrinkles, for instance, are originally a habit of mind, and then the emphasis of this, in the muscles of the face, is reflected back to deepen still further the dejection or nervous unrest that originally causes them. It is surprising to see what an influence it has on patients who go round much with wrinkled foreheads, to have them give over the practice and discipline themselves to appear with uncorrugated superciliary muscles. St. Ignatius Loyola, the founder of the Jesuits, and one of {103} the wisest managers of men that ever lived, has emphasized in one of his rules that "wrinkles on the forehead and still more on the nose" are a sign of interior disquiet and must not be seen. He realized that the interior feelings could be influenced by suggestion at least, by having those who indulged in wrinkles keep their foreheads and noses smooth. Most of the expression of the face is concerned with the eyebrows and neighboring regions, and people should occasionally be asked to look at themselves in the glass, so as to rid themselves of habits of expression indicative of a disturbed mind, for this will do much to help to relieve the mental disturbance.
