There is an old saying that man only dares use his words for three purposes, to “heal, bless or prosper.” What man says of others will be said of him, and what he wishes for another, he is wishing for himself.
If a man wishes someone “bad luck,” he is sure to attract bad luck himself. If he wishes to aid someone to success, he is wishing and aiding himself to success.
“Curses, like chickens, come home to roost.”
