Imagine the branch of a vine endowed with the power to grow according to the laws which govern it, or to ignore and disobey those laws. Imagine the same branch having made up its vegetable mind that it could live its own life apart from the vine, twisting its various fibres into all kinds of knots and snarls, according to its own idea of living, so that the sap from the main stem could only reach it in a minimum quantity. What a dearth of leaf, flower, and fruit would appear in the branch! Yet the figure is perfectly illustrative of the way in which most of us are interfering with the best use of the life that is ours.
Freedom is obedience to law. A bridge can be built to stand, only in obedience to the laws of mechanics. Electricity can be made a useful power only in exact obedience to the laws that govern it, otherwise it is most destructive. Has man the privilege of disobeying natural laws, only in the use of his own individual powers? Clearly not. And why is it that while recognizing and endeavoring to obey the laws of physics, of mechanics, and all other laws of Nature in his work in the world, he so generally defies the same laws in their application to his own being?
The freedom of an animal's body in obeying the animal instincts is beautiful to watch. The grace and power expressed in the freedom of a tiger are wonderful. The freedom in the body of a baby to respond to every motion and expression is exquisite to study. But before most children have been in the world three years their inherited personal contractions begin, and unless the little bodies can be watched and trained out of each unnecessary contraction as it appears, and so kept in their own freedom, there comes a time later, when to live to the greatest power for use they must spend hours in learning to be babies all over again, and then gain a new freedom and natural movement.
The law which perhaps appeals to us most strongly when trying to identify ourselves with Nature is the law of rhythm: action, re-action; action, re-action; action, re-action,—and the two must balance, so that equilibrium is always the result. There is no similar thought that can give us keener pleasure than when we rouse all our imagination, and realize all our power of identifying ourselves with the workings of a great law, and follow this rhythmic movement till we find rhythm within rhythm,—from the rhythmic motion of the planets to the delicate vibrations of heat and light. It is helpful to think of rhythmic growth and motion, and not to allow the thought of a new rhythm to pass without identifying ourselves with it as fully as our imagination will allow.
We have the rhythm of the seasons, of day and night, of the tides, and of vegetable and animal life,—as the various rhythmic motions in the flying of birds. The list will be endless, of course, for the great law rules everything in Nature, and our appreciation of it grows as we identify ourselves with its various modes of action.
One hair's variation in the rhythm of the universe would bring destruction, and yet we little individual microcosms are knocking ourselves into chronic states of chaos because we feel that we can be gods, and direct our own lives so much better than the God who made us. We are left in freedom to go according to His laws, or against them; and we are generally so convinced that our own stupid, short-sighted way is the best, that it is only because Nature tenderly holds to some parts of us and keeps them in the rhythm, that we do not hurl ourselves to pieces. This law of rhythm—or of equilibrium in motion and in rest—is the end, aim, and effect of all true physical training for the development and guidance of the body. Its ruling power is proved in the very construction of the body,—the two sides; the circulation of the blood, veins and arteries; the muscles, extensor and flexor; the nerves, sensory and motor.
When the long rest of a body balances the long activity, in day and night; when the shorter rests balance the shorter activity, as in the various opportunities offered through the day for entire rest, if only a minute at a time; when the sensory and motor nerves are clear for impression and expression; when the muscles in parts of the body not needed are entirely quiet, allowing those needed for a certain action to do their perfect work; when the co-ordination of the muscles in use is so established that the force for a movement is evenly divided; when the flexor rests while its antagonizing muscle works, and vice versa,— when all this which is merely a natural power for action and rest is automatically established, then the body is ready to obey and will obey the lightest touch of its owner, going in whatever direction it may be sent, artistic, scientific, or domestic. As this exquisite sense of ease in a natural movement grows upon us, no one can describe the feeling of new power or of positive comfort which comes with it; and yet it is no miracle, it is only natural. The beasts have the same freedom; but they have not the mind to put it to higher uses, or the sense to enjoy its exquisite power.
Often it seems that the care and trouble to get back into Nature's way is more than compensated for in the new appreciation of her laws and their uses. But the body, after all, is merely a servant; and, however perfect its training may have been, if the man, the master, puts his natural power to mean or low uses, sooner or later the power will be lost. Self-conscious pride will establish its own contractions. The use of a natural power for evil ends will limit itself sooner or later. The love for unwholesome surroundings will eventually put a check on a perfectly free body, although sometimes the wonder is that the check is so long in coming. If we have once trained ourselves into natural ways, so akin are the laws of Nature and spirit, both must be obeyed; and to rise to our greatest power means always to rise to our greatest power for use. "A man's life is God's love for the use for which he was made;" a man's power lies in the best direction of that use. This is a truth as practical as the necessity for walking on the feet with the head up.
