Crystal Healing: The harmonious color spectrum we see in the rainbow is reflected in the seven colors of these pendants. Many spiritual and mythological traditions‚ as well as modern practitioners of massage and color therapy, yoga, acupuncture and other modalities of wellness of body, mind and spirit‚ make use of what is called the chakra system. The word “chakra” means “wheel” and indicates a rotating circle of energy. The seven energy centers or chakras are located along the spinal column, from the tailbone to the crown of the head, and each one is associated with a color, progressing from red at the bottom to purple at the top.
