To dwell upon the negative side is always destructive. This is true of the body the same as it is true of all other things. The following from one whose thorough training as a physician has been supplemented by extensive study and observations along the lines of the powers of the interior forces, are of special significance and value in this connection: "We can never gain health by contemplating disease, any more than we can reach perfection by dwelling upon imperfection, or harmony through discord. We should keep a high ideal of health and harmony constantly before the mind. . . . "Never affirm or repeat about your health what you do not wish to be true. Do not dwell upon your ailments, nor study your symptoms. Never allow yourself to be convinced that you are not complete master of yourself. Stoutly affirm your superiority over bodily ills, and do not acknowledge yourself the slave of any inferior power. . . . I would teach children early to build a strong barrier between themselves and disease, by healthy habits of thought, high thinking, and purity of life. I would teach them to expel all thoughts of death, all images of disease, all discordant emotions, like hatred, malice, revenge, envy, and sensuality, as they would banish a temptation to do evil. I would teach them that bad food, bad drink, or bad air makes bad blood; that bad blood makes bad tissue, and bad flesh bad morals. I would teach them that healthy thoughts are as essential to healthy bodies as pure thoughts to a clean life. I would teach them to cultivate a strong will power, and to brace themselves against life's enemies in every possible way. I would teach the sick to have hope, confidence, cheer. Our thoughts and imaginations are the only real limits to our possibilities. No man's success or health will ever reach beyond his own confidence; as a rule, we erect our own barriers. "Like produces like the universe through. Hatred, envy, malice, jealousy, and revenge all have children. Every bad thought breeds others, and each of these goes on and on, ever reproducing itself, until our world is peopled with their offspring. The true physician and parent of the future will not medicate the body with drugs so much as the mind with principles. The coming mother will teach her child to assuage the fever of anger, hatred, malice, with the great panacea of the world,--Love. The coming physician will teach the people to cultivate cheerfulness, good-will, and noble deeds for a health tonic as well as a heart tonic; and that a merry heart doeth good like a medicine."
