2 Whoever has been permitted to escape by reason and contemplation from matter and this fleshly cloud or veil (whichever it should be called) and to hold communion with God, and be associated, as far as man's nature can attain, with the purest Light, blessed is he, both from his ascent from hence, and for his deification there, which is conferred by true philosophy, and by rising superior to the dualism of matter, through the unity which is perceived in the Trinity. And whosoever has been depraved by being knit to the flesh, and so far oppressed by the clay that he cannot look at the rays of truth, nor rise above things below, though he is born from above, and called to things above, I hold him to be miserable in his blindness, even though he may abound in things of this world; and all the more, because he is the sport of his abundance, and is persuaded by it that something else is beautiful instead of that which is really beautiful, reaping, as the poor fruit of his poor opinion, the sentence of darkness, or the seeing Him to be fire, Whom he did not recognize as light.
