That faith is the essential prerequisite to the successful exercise of psychic power is a proposition which has received the sanction of the concurrent experience of all the ages. Christ himself did not hesitate to acknowledge his inability to heal the sick in the absence of that condition precedent, which he held to be essential, not only to the enjoyment of the blessings which he so freely bestowed in this world, but to the attainment of eternal life. "Oh, ye of little faith," was his reproof to his followers when they returned to him and announced the decrease of their powers to heal the sick; thus proving that he regarded faith as an essential element of success, not only in the patient, but in the healer also. If the Great Healer thus acknowledged a limitation of his powers, how can we, his humble followers, hope to transcend the immutable law by which he was governed? "Why is it that our belief has anything to do with the exercise of the healing power?" is a question often asked. To this the obvious and only reply is that the healing power, being a mental, or psychic, force, is necessarily governed by mental conditions. Just why faith is the necessary mental attitude of the patient can never be answered until we are able to fathom the ultimate cause of all things. The experience of all the ages shows it to be a fact, and we must accept it as such, and content ourselves with an effort to ascertain its relations to other facts, and, if possible, to define its limitations and ascertain the means of commanding it at will. It is safe to say that the statement of the fact under consideration has done more to retard the progress of the science of psychic healing than all other things combined. The sceptic at once concludes that, whatever good the system may do to credulous people, it can never be of benefit to him, because he "does not believe in such things." And it is just here that the mistake is made,--a mistake that is most natural in the present state of psychic knowledge, and one that is all but universal. It consists in the assumption that the faith of the objective mind has anything to do with the requisite mental attitude. The reader is again requested to call to mind the fundamental propositions of the hypothesis under discussion, namely, the dual personality and the power of suggestion. It follows from the propositions of our hypothesis, which need not be here repeated at length, that the subjective mind of an individual is as amenable to control by the suggestions of his own objective mind as it is by the suggestions of another. The law is the same. It follows that, whatever may be the objective belief of the patient, if he will assume to have faith, actively or passively, the subjective mind will be controlled by the suggestion, and the desired result will follow.
