One of the most commonly used tools for divination and dowsing is a pendulum. The art of using a pendulum is something that anyone can learn and master, and enjoy experimenting with.A pendulum is a symmetrical, weighted object that is hung from a single chain or cord. It’s never made of a magnetic substance, but is often a crystal. It’s also possible to use objects such as a favourite trinket, a bead, a metal ball or even a key. The pendulum is a very simple tool and one that lets the user tune in to their intuitive powers. The pendulum acts as a receiver and transmitter of information, and moves in different ways in response to questions.
