Each Chakra or energy center has a measurable pattern of electromagnetic activity to which it is naturally “tuned” when it is flowing in balance, or aligned. Placing a vibrating tuning fork on a chakra, it initiates sound frequencies that stimulate the body to create the frequencies it needs to bring itself into alignment. It is similar to striking a musical tuning fork and finding nearby tuning forks vibrating in harmony. The electromagnetic field of the body is recharged and the flow of Chi energy is re-established. Precisely-tuned (to .01Hz) aluminum tuning forks include a Velvet carrying pouch and FREE Mallet Activator! .
