Pendulum & dowsing rods

Pendulums are often used as tools for spiritual healing and inner growth. Defined as objects attached at the end of a string or metal chain, when suspended from a stationary position, a pendulum will swing back and forth or in a circular motion. 

The typical image of a pendulum is that of an object with four metal balls, such as that on an employee's desk, also known as Newton's pendulum. Alternatively, the image of a pendulum watch clock swinging back and forth may ring a bell.
