Back, back, forth and forth
Pendulums are a way to communicate to your higher self & spirit guides by answering yes or no questions. At first, the pendulum will vibrate to pick up your energy. Test it by asking it to show you a YES. Then test again asking it to show you a NO. YES are definite by the pendulum swinging left and right and circling clockwise. NO swings back and forth and circles counterclockwise.
