Even what we call matter or substance, and all that does not seem to speak or sound, is in reality all vibration. And the beauty of the whole of creation is this, that creation has worked in two ways. In one way it has expressed and in the other way it has made itself a responsive mold. For instance, there is substance, matter to touch, and there is a sense to feel, to touch. There is a sound, and at the same time there are ears which can hear sound. There is light, there is form, there are colors; and at the same time there are eyes to see them. And what man calls beauty is the harmony of all one experiences. What after all is music? What we call music is the harmony of the audible notes; but in reality there is music in color, there is music in lines, there is music in the forest where there is a variety of trees and plants; and there is harmony in how they correspond with each other. The more widely one observes nature, the more it appeals to one's soul. Why? Because there is a music there; and the wider one's outlook on life becomes, the deeper one's understanding of life, the more music one can listen to, the music which answers the whole universe. But the one whose heart is open need not go as far as the forest; in the midst of the crowd he can find music. At this time human ideas are so changed, owing to materialism, that there is hardly any distinction of personality. But if one studies human nature, one sees that even a piano of a thousand octaves could not reproduce the variety of human nature.
