SAGITTARIUS (Nov. 22-Dec. 21): Each of us has at least one pesky ghost or nagging demon that occupies a dark corner of our psyches. It may have been there for years, or we might have picked it up more recently during a phase of temporary insanity. In any case, most of us can benefit from conducting a periodic banishing ritual. Now would be prime time for you to do just that. Ready? With your imagination, draw a clockwise circle of your favorite-colored light on the floor or ground. Next, identify an image that makes you feel happy and safe, and visualize four versions of it at the four cardinal points, hovering three feet above your circle. Then say this: “I dissolve any hex and banish any pest that has been draining my energy. I purge any wasteful emotions, unsound ideas, and trivial desires that I may have grown attached to.” To put the seal on your magic, laugh for two minutes.
