This is rather advanced sorcery, but with a little perseverance, you may be able to bring it off. (It's marvelous for coping with in-laws, tyrannical bosses, uncooperative employees, etc.) Find a pocket size mirror that's set in a wooden frame. Encircle it with ivy and put it, with the ivy still attached, face up in a pail of water. Leave it outdoors, in a place where it will be exposed to, the rays of the new moon for an entire night.
In the morning, take out the mirror and dry it. Carry it with you, in a hidden place, from that moment on. When the person you want to influence comes near, look into the mirror (but don't let him see the mirror or your glance into it). Then look into his eyes. Keep doing this until you find the person more and more willing to accept suggestions from you. One day you may have him completely in your power.
