XX. Know thou of a certainty that the Unseen can in no wise incarnate His Essence and reveal it unto men. He is, and hath ever been, immensely exalted beyond all that can either be recounted or perceived. From His retreat of glory His voice is ever proclaiming: "Verily, I am God; there is none other God besides Me, the All-Knowing, the All-Wise. I have manifested Myself unto men, and have sent down Him Who is the Day Spring of the signs of My Revelation. Through Him I have caused all creation to testify that there is none other God except Him, the Incomparable, the All-Informed, the All-Wise." He Who is everlastingly hidden from the eyes of men can never be known except through His Manifestation, and His Manifestation can adduce no greater proof of the truth of His Mission than the proof of His own Person. (49:1)
XXI. O Salman! The door of the knowledge of the Ancient Being hath ever been, and will continue for ever to be, closed in the face of men. No man's understanding shall ever gain access unto His holy court. As a token of His mercy, however, and as a proof of His loving-kindness, He hath manifested unto men the Day Stars of His divine guidance, the Symbols of His divine unity, and hath ordained the knowledge of these sanctified Beings to be identical with the knowledge of His own Self. Whoso recognizeth them hath recognized God. Whoso hearkeneth to their call, hath hearkened to the Voice of God, and whoso testifieth to the truth of their Revelation, hath testified to the truth of God Himself. Whoso turneth away from them, hath turned away from God, and whoso disbelieveth in them, hath disbelieved in God. Every one of them is the Way of God that connecteth this world with the realms above, and the Standard of His Truth unto every one in the kingdoms of earth and heaven. They are the Manifestations of God amidst men, the evidences of His Truth, and the signs of His glory.
