This beautiful Crescent Moon Protection Pentagram Necklace can be worn to shield and protect you or you can also use this as a Pendulum. A pendulum is an object hung from a fixed point that swings back and forth under the action of gravity. ... The swing continues moving back and forth without any extra outside help until friction (between the air and the swing and between the chains and the attachment points) slows it down and eventually stops it. You can program your pendulum to help you answer questions in a form of yes, no, maybe. The way you program the pendulum is you first show it which direction means what answer. Typically when it moved up and down that means yes, when it moves from side to side that means NO and when it moves around in a circle means maybe. After you show your pendulum which means what answers , to make sure it was programmed correctly you ask it to show you what means yes and so on. You are not moving the pendulum you are just holding it and the energies around you will guide and give you the answers you are seeking.
