What man calls beauty is the harmony of all he experiences. What after all is music? What we call music is the harmony of the audible notes. 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, in the way in which 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 to the extent to which one sees more deeply into life and observes life more widely, one listens to more and more music - the music which answers the whole universe.
