Just a word or two in regard to their mode of operation. If a person is dominated for a moment by, say a passion of anger, there is set up in the physical organism what we might justly term a bodily thunder-storm, which has the effect of souring, or rather of corroding, the normal, healthy, and life-giving secretions of the body, so that instead of performing their natural functions they become poisonous and destructive. And if this goes on to any great extent, by virtue of their cumulative influences, they give rise to a particular form of disease, which in turn becomes chronic. So the emotion opposite to this, that of kindliness, love, benevolence, good-will, tends to stimulate a healthy, purifying, and life-giving flow of all the bodily secretions. All the channels of the body seem free and open; the life forces go bounding through them. And these very forces, set into a bounding activity, will in time counteract the poisonous and disease-giving effects of their opposites. A physician goes to see a patient. He gives no medicine this morning. Yet the very fact of his going makes the patient better. He has carried with him the spirit of health; he has carried brightness of tone and disposition; he has carried hope into the sick chamber; he has left it there. In fact, the very hope and good cheer he has carried with him has taken hold of and has had a subtle but powerful influence upon the mind of the patient; and this mental condition imparted by the physician has in turn its effects upon the patient's body, and so through the instrumentality of this mental suggestion the healing goes on. "Know, then, whatever cheerful and serene Supports the mind, supports the body, too. Hence the most vital movement mortals feel Is _hope_; the balm and life-blood of the soul." We sometimes hear a person in weak health say to another, "I always feel better when you come." There is a deep scientific reason underlying the statement. "The tongue of the wise is health." The power of suggestion so far as the human mind is concerned is a most wonderful and interesting field of study. Most wonderful and powerful forces can be set into operation through this agency. One of the world's most noted scientists, recognized everywhere as one of the most eminent anatomists living, tells us that he has proven from laboratory experiments that the entire human structure can be completely changed, made over, within a period of less than one year, and that some portions can be entirely remade within a period of a very few weeks.
