Soul of the soul! Neither thought nor reason com-prehends thy essence, and no one knows thy attributes. Souls have no idea of thy being. The prophets them-selves sink in the dust of thy road. Although intellect exists by thee, has it yet ever found the path of thy existence?
O Thou who art in the interior and in the exterior of the soul, thou art and thou art not that which I say. In thy presence, reason grows dizzy; it loses the thread that would direct it in thy way. I perceive clearly the universe in thee, and yet discover thee not in the world. All beings are marked with thy impress, but thyself hast no impress visible. Thou reservest the secret of thine existence.
