Also known as dowsing, pendulum magic is a technique for seeing into the future, whether for information about romance, luck, past lives, or the psychic causes of disease.
The author gives step-by-step instructions for making pendulums with everything from gemstones and rings to buttons and fishing weights.
She explains how questions should be asked and how answers should be interpreted. She also charts the rituals involved in divination and explains how to use pendulums in conjunction with tarot cards, crystals, astrology, and meditation.
