On account of the many misconceptions of the nature of human development, will it not be well, before beginning our program to consider seriously--What is training? What are some of its principles? What can we do with ourselves by obeying nature's laws? Or, if these questions are too serious, too difficult for a short answer, should we not, at least, try to realize what is an exercise? To many persons, any kind of movement, any jerk or chaotic action, is an exercise. They think that the more effort put forth, the better. Thus some teachers of voice contend that, to be an exercise, there must be muscular effort in producing tone. On the contrary, many movements are injurious; unnecessary effort will defeat some of the most important exercises. The exercise must obey the laws of nature. It must fulfill nature's intentions, stimulate nature's processes, awaken normal, though slumbering activity. An exercise is of fundamental importance to all human beings. Man comes into the world the feeblest of all animals. He has the least power to do anything for himself, but he comes with possibilities of higher love and union with his fellow-men. He comes into the world with a greater possibility of unfolding than any other created being. Accordingly an exercise is a means of progress, a simple action which a man must use for his own unfoldment. An exercise is a conscious step toward an ideal. Man is given the prophetic power to realize his own possibilities. We can hardly imagine an exercise independent of the conscious sense of the highest and best attainments, of thereby making ourselves stronger and in some way better. This ideal is instinctive, even on the part of animals, in fact, the animal instinctively regards its own preservation, its own unfoldment and the reaching of its ideal type. A tree will cover up its wound and reach out its branches freely, spontaneously in the direction of the light and toward the attainment of its own type. With man the ideal is a matter of higher realization. We have the lower instincts in common with the animals but we have also something higher. There is inborn in us a conception that man transcends all present conditions. An exercise is a step towards the attainment of a chosen end. Accordingly we have high exercises and low exercises; exercises on a mental and on a physical plane; exercises that may train men down to an abnormal type; exercises also that are intellectual, imaginative and spiritual. Everywhere in nature there is a low and a high. In animals of a high order of unfoldment there is specific functioning of every part but in those of a low order the functions are confused. The organs are not so well differentiated. Even in human beings, in the process of degeneracy a man loses a greater variety of his powers, and his very voice and body lose some of those characteristics which belong to the ideal member of the race.
