Of course the mind and its rapid and misdirected working is a strong preventive of free nerves, relaxed muscles, and natural sleep. "If I could only stop myself from thinking" is a complaint often heard, and reason or philosophy does not seem to touch it. Even the certain knowledge that nothing is gained by this rapid thought at the wrong time, that very much is lost, makes no impression on the overwrought mind,--often even excites it more, which proves that the trouble, if originally mental, has now gained such a hold upon the physique that it must be attacked there first. The nerves should be trained to enable the body to be an obedient servant to a healthy mind, and the mind in giving its attention to such training gains in normal power of direction. If you cannot stop thinking, do not try; let your thoughts steam ahead if they will. Only relax your muscles, and as the attention is more and more fixed on the interesting process of letting-go of the muscles (interesting, simply because the end is so well worth gaining), the imps of thought find less and less to take hold of, and the machinery in the head must stop its senseless working, because the mind which allowed it to work has applied itself to something worth accomplishing. The body should also be at rest in necessary reclining in the day, where of course all the laws of sleep apply. Five minutes of complete rest in that way means greater gain than an hour or three hours taken in the usual manner. I remember watching a woman "resting" on a lounge, propped up with the downiest of pillows, holding her head perfectly erect and in a strained position, when it not only would have been easier to let it fall back on the pillow, but it seemed impossible that she should not let it go; and yet there it was, held erect with an evident strain. Hers is not an unusual case, on the contrary quite a common one. Can we wonder that the German doctor thought he had discovered a new disease? And must he not be already surprised and shocked at the precocious growth of the infant monster which he found and named? "So prone are mortals to their own damnation, it seems as though a devil's use were gone." There is no better way of learning to overcome these perversions in sleep and similar forms of rest, than to study with careful thought the sleep of a wholesome little child. Having gained the physical freedom necessary to give perfect repose to the body, the quiet, simple dropping of all thought and care can be made more easily possible. So we can approach again the natural sleep and enjoy consciously the refreshment which through our own babyhood was the unconscious means of giving us daily strength and power for growth.
