Chakra is a Sanskrit word meaning disk or wheel.  These wheels are energy centers located in our body, and each chakra is associated with certain organs and nerves throughout the body.  When your chakras are out of balance, your body can experience it in the form of poor concentration, fatique, and tension in the neck and shoulders to name a few.  By using tuning forks that are tuned to the chakra's frequencies, the vibrations of the tuning forks can help unblock and open them, helping your body to be able to heal and balance itself.  I use the traditional Hindu chakras to unblock and balance them, along with the Sufi chakras to help swirl them to get the chakras to work together.
