Vibrations as a rule have length as well as breadth [frequency and amplitude], and they may last the least fraction of a moment or the greater part of the age of the universe. They make different forms, figures and colors as they shoot forth, one vibration creating another; thus myriads arise out of one. In this way there are circles under circles and circles over circles, all of which form the universe. Every vibration after its manifestation becomes merged again in its original source.
