Now one may say: What music may this be? If there were no harmony in the essence of life, life would not have created harmony in this world of variety. Man would not have longed for something which was not already in his spirit. Everything in this world which seems to lack harmony is in reality the limitation of man's own vision. The wider the horizon of his observation becomes, the more harmony of life he enjoys. In the very depth of man's being the harmony of the working of the whole universe sums up in a perfect music. Therefore, the music which is the source of creation, the music which is found near the goal of creation, is the music of the spheres. And it is heard and enjoyed by those who touch the very depth of their own lives.
