O Supreme Light, that so high upliftest Thyself from moral conceptions, relend to my mind a little of what thou didst appear, and make my tongue so powerful that it may be able to leave one single spark of thy glory for the folk to come … O Abundant Grace, whereby I presumed to fix my look through the Eternal Light till that there I consummated the seeing! I saw that in its depth is enclosed, bound up with love in one volume, that which is dispersed in leaves through the universe. … One single moment only is greater oblivion for me than five-and-twenty centuries … Thus my mind, wholly rapt, was gazing fixed, motionless, and intent, and ever with gazing grew enkindled. In that Light one becomes such that it is impossible he should ever consent to turn himself from it for other sight; because the Good which is the object of the will is all collected in it, and outside of it that is defective which is perfect there.
Divine Comedy, Paradiso (Canto 33)
