For why, my brothers and sisters, would you rejoice in silver? Either your silver will perish, or you will, and no one knows which will perish first. For neither can you remain here always, nor can silver remain here always; so also with gold, wardrobes, houses, money, real estate-and in the end, even the light by which we enjoy all these things. So do not be willing then to rejoice in such things as these. Rejoice instead in the light that has no setting; rejoice in the dawn which no yesterday precedes, and no tomorrow follows.
Saint AugustineMen go forth to marvel at the height of mountains, and the huge waves of the sea, the broad flow of the rivers, the vastness of the ocean, the orbits of the stars, and yet they neglect to marvel at themselves. Variant: Men go abroad to admire the heights of mountains, the mighty billows of the sea, the broad tides of rivers, the compass of the ocean, and the circuits of the stars, and pass themselves by.
