How to use a chakra pendulum: 
Begin by laying down on your back (or, if you are performing the chakra pendulum exercise on someone else, have them lie on their back on a surface that is tall enough for you to have a comfortable position and not be leaning into them. You do not want to create a “push,” where you are pushing energy from your field into theirs). Holding the cord of the pendulum between your thumb and forefinger about 4-6 inches above each chakra. When the pendulum moves, observe its direction and movement.
If the pendulum moves clockwise, that chakra is open, well-balanced, and full.
If the pendulum moves counter-clockwise, there may be blocked energy or unreleased emotions relating to that specific chakra.
If the pendulum moves in an elliptical swing, there may be a right- or left-side imbalance of energy flowing in the body. This may be due to overusing the right masculine side or the left nurturing side.
If the pendulum moves in an erratic swing, it is possible that you (or the person you are performing the chakra pendulum exercise on) may have recently changed a belief or is going through a spiritual upheaval, which can affect the chakra’s movement and cause it to move erratically for a couple of days.
 If the pendulum does not move at all, you may be holding the pendulum in the incorrect location. If that is not the case, then there may be a blockage in that chakra.
