Eighth window: The testimony of all Prophets (those people with luminous spirits), based on their manifest and evident miracles; the testimony of all saints (those distinguished with illumined hearts), relying on their wonder-making and spiritual discoveries; and the testimony of all purified scholars (those with enlightened minds who rely on their research and quest for truth), all testify to the necessary Existence and Unity of One, the Creator of all things, and His Power's perfection. They form a vast and enlightening window through which His Lordship—sustaining, training, raising, etc.—shows itself continually. Who do you rely on so that you do not heed those people? Or, by closing your eyes in the daytime, do you imagine the world to be in darkness?
