This eye we have it in our own power to create, and to make it quicksighted and beautiful. For when we direct it, not to the smoke nor to the dust (for such are all human things), but to the delicate breeze, to the light air, to things heavenly and high, and full of much calmness and purity, and of much delight, we shall speedily restore it, and shall invigorate it, as it luxuriates in such contemplation. Hast thou seen covetousness and great wealth? do not thou lift up thine eye thereto. The thing is mire, it is smoke, an evil vapor, darkness, and great distress and suffocating cares. Hast thou seen a man cultivating righteousness, content with his own, and having abundant space for recreation, having anxieties, not fixing his thoughts on things here? Set [thine eye] there, and lift [it] up on high; and thou wilt make it far the most beautiful, and more splendid, feasting it not with the flowers of the earth, but with those of virtue, with temperance, moderation, and all the rest. For nothing so troubles the eye as an evil conscience (“Mine eye,” it is said, “was troubled by reason of anger”— Ps. vi. 7 ); nothing so darkens it. Set it free from this injury, and thou wilt make it vigorous and strong, ever nourished with good hopes.
