The following treatment given as an example by F. W. Southworth, M. D., in his little book on "True Metaphysical Science, and its Practical Application through the Law of Suggestion," furnishes an excellent illustration of the form of suggestive treatment favored by this particular school. The patient is addressed as follows: "As thoughts are not only things, but forces and act upon our mental and physical life for good or ill, we must be careful to always keep ourselves in that condition of thought which builds up and strengthens, to constantly think thoughts of _health_, of _happiness_, of _good_, to be _cheerful_, hopeful, confident and fearless. (Repeat five or six times.) In order to sustain this condition of positive thinking it requires the development of the will power. The will is the motive power and the controlling force in all aspects of our life, but we develop it especially for the concentration and control of thought. This is the higher self--the infinite will. Exercise it with vigor and earnest persistency, and learn to _rely_ upon it. Assert its power as you assert the power of the muscles in exercise and it will manifest itself and the thought will be positive, the secretions of the body will be normal, and the circulation of the blood in the head will be kept at that proper equilibrium which insures the constant nutrition of the cells of the brain and their constant vigor and strength of control of all the organs and tissues of the body, and this vast and intricate machinery of the body will work harmoniously for the production of nutrition through elaboration of the food elements. "As our body is constantly changing and wasting, we must rebuild and restore it constantly, and we do so from the air we breathe, the water we drink, and the food we eat. The most important of these is the air you breathe, as it is not only a food in itself to the tissues, but it vitalizes the food you eat and the water you drink. Give it that quality of your thought and breathe it as you have been directed at least six times per day for a period of from five to ten minutes each time. Recognize it as both a food and an eliminator of poisons, as it is, and breathe, breathe, breathe, by Nature's method, and the lungs will distribute the oxygen to the blood, and the blood being the common carrier of the body will take it to all parts of the body and on its return will gather up all the waste and poisonous matters and will bring them to the lungs, where, meeting the fresh oxygen, they will be burned up and exhaled as carbonic acid gas, leaving the body pure and clean.
