WHAT MAKES THE PENDULUM MOVE?
Thought directs the subconscious as to which direction the pendulum is to move. The subconscious mind uses the brain to send signals along the neurological pathways that control the muscle twitches that move the pendulum in the desired direction.
WHY USE A PENDULUM?
To gain information from:
1) Your subconscious mind
2) Your body and cells of your body
3) Your Higher Self (the intuitive spiritual part of your spirit)
NOTE: Your subconscious mind is what moves the pendulum, not spirit.
