Here we have an instance of intentional sparing, a thing related to relaxation, for both are an economy of force. And in this body of ours, so “fearfully and wonderfully made,” servant as it is or should be to the will, a conscious command is far more binding than a _laisser aller_. A man with a severe headache may be unable to go to sleep in the ordinary course, but let him learn to know and practise the use of the huge power of will that is lying chiefly dormant within him, and he will not only be able to get on satisfactorily with his work, which would be impossible if he paused to think how his head hurt, but he will easily be able to go to sleep. He could, and the ordinary man can, if he tries, induce by practice both energy and passivity. But there are “foes of its own household” even here, as in Vegetarianism and Teetotalism. And the hearth-abiding foe of the power of the will is Christian Science. This strange sect holds that _all_ ailments are imaginary, and that since there is no matter, there is no such thing as a broken leg, because there is no leg. This is futile, and the answer incontestably is that there must be legs because they can be broken. But the subject is not worth discussion. Again, to sum up:-- (i.) To mean to do a thing is productive of better results than to let the thing happen. (ii.) Therefore, let your will intend rest, and you will get rest more effectively than by lying down. (iii.) You do not tire the will by using it. On the contrary, it is only by its use that it can get strong. (iv.) There are two things that weaken the will: the first is not using it, the second is not obeying it. CHAPTER VIII. THE INFLUENCE OF TRAINING ON MIND AND MORALS. It is impossible to make the simplest movement of any kind without the conscious or unconscious direction of the mind, so inextricably are the two bound up together; and from the earliest times physicians, both spiritual, mental and physical, have known that the soul can be reached through the “subtle gateways of the body.” This aspect of training, the importance, that is, of the cleanly health of the body, and its prompt and unrebellious obedience to the will, which is concerned with this question, has been alluded to before, and is dealt with more fully here.
