"Can the sun ... be regarded as equal in rank to darkness?"

"Furthermore, consider the signs of the revelation of God in their relation one to another. Can the sun, which is but one of these signs, be regarded as equal in rank to darkness? The one true God beareth Me witness! No man can believe it, unless he be of those whose hearts are straitened, and whose eyes have become deluded. Say: Consider your own selves. Your nails and eyes are both parts of your bodies. Do ye regard them of equal rank and value? If ye say, yea; say, then: ye have indeed charged with imposture, the Lord, my God, the All-Glorious, inasmuch as ye pare the one, and cherish the other as dearly as your own life."
