A Pendulum can be used for checking the health and spin of the chakras prior to a Reiki Session. You can buy Crystal reiki pendulum online in India. When checking the seven major chakras, they will spin in a 6” wide clockwise circle when they are open and “normal”. Any other spin is not “normal” and indicates an area that needs extra Reiki. These other spins could be horizontal, vertical, diagonal, elliptical, counter-clockwise, or even completely still.
