"In all the Divine Books the promise of the Divine Presence hath been explicitly recorded. By this Presence is meant the Presence of Him Who is the Dayspring of the signs, and the Dawning-Place of the clear tokens, and the Manifestation of the Excellent Names, and the Source of the attributes, of the true God, exalted be His glory. God in His Essence and in His own Self hath ever been unseen, inaccessible, and unknowable. By Presence, therefore, is meant the Presence of the One Who is His Vicegerent amongst men. He, moreover, hath never had, nor hath He, any peer or likeness. For were He to have any peer or likeness, how could it then be demonstrated that His being is exalted above, and His essence sanctified from, all comparison and likeness? Briefly, there hath been revealed in the Kitáb-i-Íqán (Book of Certitude) concerning the Presence and Revelation of God that which will suffice the fair-minded. We beseech Him—exalted be He—to aid every one to become the essence of truthfulness, and to draw nigh unto Him. He, verily, is the Lord of strength and power. No God is there but Him, the All-Hearing, the Lord of Utterance, the Almighty, the All-Praised."
