Man must realise that as a purely personal being he can do nothing, but as a child of God, he is endowed potentially with omniscience and omnipotence, for it is God that worketh within him to will and to do. No man liveth to himself, no man dieth to himself. One Life and One Intelligence guides and directs all alike. One Will and One Power lives and moves in all souls, whether developed or undeveloped, but the undeveloped is all unconscious of this, whereas the one who is developed is thoroughly conscious that of himself he is nothing - that it is God working in him, and because of this he is able to accomplish everything in life that he wills to do. To such a one life becomes filled with unlimited possibilities. All the littleness, all the meanness is swallowed up, or, I might say, all shadows are left behind when one presses forward in accordance with the Divine Will. Such a one is preparing himself, through living a beautiful and harmonious life, to see more and more of the beauty and harmony of the great outer world in which he lives. Nature is his mirror in which he sees himself as he is. If he brings joy and gladness, if he brings peace and goodwill, if he brings gentleness and kindness to the mirror, he is going to see with the eyes of the Lord, and the eyes of the Lord are too pure to behold iniquity. To the pure in heart all things are pure. Life gives him back that which he brings to it. Man is not left to the condemnation or mercy of anything save his own ideals, for he rewards or punishes himself as he consciously obeys or disobeys the laws of life. The development of his own life is committed to his own care. He has everything necessary wherewith to work out every hidden power, every unseen possibility; but it is through work that it is all accomplished. Through work he can make his life what he wills to make it.

Man is master of his own fate. He is neither controlled by circumstances nor environment. He can be as great as his highest ideal, but only through conformity to the laws which regulate all life. He must learn to feel the real rhythm of being; he must express that rhythm through melody; he must so adjust his mind to both his inner and outer life that he uses harmony in a perfect way. If he is doing this, then he is fulfilling the laws of life and reaping the true reward of his own right actions. When man lives in this way, he not only experiences greater health and happiness, but he is bringing an influence to bear upon the lives of others that will make for untold good. The world to-day is asking for light, for more light, and if anyone can show a way of living that will bring greater health and happiness to it, that is of more importance than many theories that do not deal with the life of man in a practical way. The ideal and the practical must go hand in hand. Theories may be wonderful and beautiful, but if they are lacking in practical good, then the dwelling on such theories is only a waste of time. The need of the world to-day is for something that will bring to it more of joy and peace, more of health and happiness, and anyone who can suggest that which will help to do this, is a real benefactor in the highest and best sense of the word. In giving to the world my suggestions for the use of music and colour I am convinced that all real betterment of mankind must come first through inner feeling and idealistic thought, then through the unfolding of these two qualities there will ensue fuller and freer expression in man's outer world and life; for life and its full development is a much deeper thing than its outer environment, a much higher thing than food, drink, and raiment; for while the latter are necessary, it is still more essential that man should seek to develop his whole nature, his soul, his mind, and his body, so that the whole man may be quickened and renewed from centre to circumference. If I can suggest in this book that which will help toward such an end, then I shall be fully satisfied. I firmly believe, however, that a time will come when the world's ills, whether of a mental or a physical nature, shall not only be helped, but actually healed through the scientific use of music and colour; and it is to that particular end that I wish to direct the minds of those desirous of investigating the subject in a thorough way, as well as to awaken the interest of the nonprofessional reader. I am fully aware of the fact that, in a desultory way, music has been and is being used in institutions in different parts of the country with varying results. It is my sincere desire, however, to see the whole question taken up in a thoroughly scientific way, and every phase of the subject not only investigated, but the results tabulated, to the end that a real system of scientific therapeutics may be established that shall meet the needs and requirements of every form of disease, whether it be disease of mind or of body. Furthermore, if such a system were once inaugurated, it would pre-exclude the quack or the superficial practitioner; because if music and colour become an exact science of healing, then before one might hope to practise it, it would be necessary to be scientifically trained. The practitioner would of necessity have been obliged to make a thorough study of music and colour, and their effects upon the varying temperaments of people, and be able to diagnose the nature of the trouble, and prescribe the needed remedy.

A system of music and colour therapeutics, too, would without doubt do as much good to the doctor as to his patients, for at the present time the medical doctor is so absorbed in his material remedies, that the whole trend of his work shapes his mind toward a materialistic view of life. This tends, in turn, to destroy intuition and real imagination, and makes the man as material as his remedies. It is not my wish to be in any way antagonistic to medical doctors. I should not be carrying out the principles I try to inculcate in this book if I were. My thought, therefore, is not directed against the men who practise the present systems of healing, but rather against the systems themselves. The world has had many systems of healing with material remedies in its time, and all have been tried and found wanting. The systems of the future will have to take this one fact into consideration, that man is a living soul possessed of a body, and that the body's needs can best be supplied by the healing properties of the soul. Everything necessary to health, strength, and happiness is resident in man's life, and when he uses the power in his possession to control to the full the forces of his own life, he will be successful, not only in overcoming disease with health, but in everything that he undertakes. He will grow in wisdom and stature, and eventually will become a law unto himself, having dominion and power over all things.
