Enchiridion 18

“When a raven has croaked inauspiciously, let not the appearance hurry you away with it; but straightway make a distinction in your mind and say, None of these things is signified to me, but either to my poor body, or to my small property, or to my reputation, or to my children, or to my wife: but to me all significations are auspicious if I choose. For whatever of these things results, it is in my power to derive benefit from it.”
