Both from the point of view of the Sufi and that of all mystics, the original state of the whole creation is a vibration, and the vibration manifests in two forms or stages. In its original condition the vibration is inaudible and invisible, but in its first stage toward manifestation it becomes audible, and in its next step visible. In its audible stage it is called 'Nada' in Vedantic terms, a word which means 'sound'; or 'Nada-Brahma' which represents 'sound the Creator,' 'sound the Creative Spirit.'
