Here's another thing to try. When you're enjoying something, picture the opposite happening. What's the harm in whispering to your child while you kiss them: "Tomorrow you might die"? Or saying to a friend: "Tomorrow you might leave, or I might, and we'll never see each other again"? You think these are unlucky words to say? Some magic spells sound unlucky too, but if they work, I don't care how they sound. They just need to be useful. What makes words truly unlucky anyway? Only words that point to real evils. Cowardice is unlucky. A weak spirit is unlucky. Sadness, grief, and shamelessness — those are unlucky words. But we should still say them when we need to protect ourselves from these things. Are you really going to tell me that any word describing something natural is unlucky?
And further, at the times when you are delighted with a thing, place before yourself the contrary appearances. What harm is it while you are kissing your child to say with a lisping voice: To-morrow you will die; and to a friend also: To-morrow you will go away or I shall, and never shall we see one another again? But these are words of bad omen—and some incantations also are of bad omen; but because they are useful, I don't care for this; only let them be useful. But do you call things to be of bad omen except those which are significant of some evil? Cowardice is a word of bad omen, and meanness of spirit, and sorrow, and grief, and shamelessness. These words are of bad omen; and yet we ought not to hesitate to utter them in order to protect ourselves against the things. Do you tell me that a name which is significant of any natural thing is of evil omen?
