The whole science of psycho-therapeutics is embraced in the foregoing propositions. They contain all that a patient, who undertakes to heal himself or to ward off the encroachments of disease, needs to know. The process of making a particular application of these principles is equally simple, and must be obvious to the intelligent reader. At the risk of repetition, a few general directions will be given. We will take, for illustration, a simple case of nervous headache, and suppose that the patient resolves to cure himself. He must, first of all, remember that the subjective mind is to be treated precisely as though it were a separate and distinct entity. The suggestion must first be made that the headache is about to cease; then, that it is already ceasing; and, finally, that it has ceased. These suggestions should be made in the form of spoken words, and they should be steadily persisted in until the desired effect is produced. A constant reiteration of the declaration that the head is better will inevitably produce the desired result; and, when the effect is distinctly felt, the declaration should be boldly made that the pain has entirely ceased. If any remnants of the pain are felt, the fact should be ignored, and the suggestion persisted in that it has ceased. This should be followed by the declaration that there will be no return of the symptoms; and this should be made with an air, tone, and feeling of perfect confidence. The only practical difficulty and obstacle in the way of success with a beginner lies in the fact that at first he lacks confidence. The education of his whole life has been such as to cause him to look with distrust upon any but material remedies, and there is a disinclination to persist in his efforts. But he should remember that it is the suggestions conveyed by this very education that he is now called upon to combat, neutralize, and overcome by a stronger and more emphatic counter-suggestion. If he has the strength of will to persist until he is cured, he will find that the next time he tries it there will be much less resistance to overcome. Having once triumphed, the reasoning of his objective mind no longer interposes itself as an obstruction, but concurs in the truth of his suggestions. He then possesses both objective and subjective faith in his powers, and he finds himself operating on a line of no resistance whatever. When he has attained this point, the rest is easy; and he will eventually be able to effect an instantaneous cure of his headache, or any other pain, the moment he finds himself threatened with one. These remarks apply, of course, to every disease amenable to control by mental processes.
