So far as the mere muscular movement goes, the sensation is that of being well oiled. As for instance, in a natural walk, where the swinging muscles and the standing muscles act and rest in alternate rhythmic action, the chest is held high, the side muscles free to move in, harmony with the legs, and all the spring in the body brought into play through inclining slightly forward and pushing with the ball of the back foot, the arms swinging naturally without tension. Walking with a free body is often one of the best forms of rest, and in the varying forms of motion arranged for practice we are enabled to realize, that "perfect harmony of action in the entire man invigorates every part." XIV. MIND TRAINING IT will be plainly seen that this training of the body is at the same time a training of the mind, and indeed it is in essence a training of the will. For as we think of it carefully and analyze it to its fundamental principles, we realize that it might almost be summed up as in itself a training of the will alone. That is certainly what it leads to, and where it leads from. Maudsley tells us that "he who is incapable of guiding his muscles, is incapable of concentrating his mind;" and it would seem to follow, by a natural sequence, that training for the best use of all the powers given us should begin with the muscles, and continue through the nerves and the senses to the mind,--all by means of the will, which should gradually remove all personal contractions and obstructions to the wholesome working of the law of cause and effect. Help a child to use his own ability of gaining free muscles, nerves clear to take impressions through every sense, a mind open to recognize them, and a will alive with interest in and love for finding the best in each new sensation or truth, and what can he not reach in power of use to others and in his own growth. The consistency of creation is perfect. The law that applies to the guidance of the muscles works just as truly in training the senses and the mind. A new movement can be learned with facility in proportion to the power of dropping at the time all impressions of previous movements. Quickness and keenness of sense are gained only in proportion to the power of quieting the senses not in use, and erasing previous impressions upon the sense which is active at the time.
