“There was God and there was naught beside Him.”

"O friend, till thou enter the garden of such mysteries, thou shalt never set lip to the undying wine of this Valley. And shouldst thou taste of it, thou wilt shield thine eyes from all things else, and drink of the wine of contentment; and thou wilt loose thyself from all things else, and bind thyself to Him, and throw thy life down in His path, and cast thy soul away. However, there is no other in this region that thou need forget: “There was God and there was naught beside Him.”4 For on this plane the traveler witnesseth the beauty of the Friend in everything. Even in fire, he seeth the face of the Beloved. He beholdeth in illusion the secret of reality, and readeth from the attributes the riddle of the Essence. "...
