The Charkas are energy centers of the body that have physical, energetic and spiritual components. There are 7 primary chakras. Each one is associated with glands that make up the endocrine system. Glands are responsible for the body's hormone regulation and production. Hormones play a vital role in body functioning, development, metabolism, sleep, and mood. Crystals may be used as conscious and energetic tools to activate, balance, and align chakras so that the body and mind can function optimally.
