The word Reiki, is comprised of two Japanese words. ‘Rei’, which means ‘God, or Higher Power’ and ‘Ki’, which means ‘life force energy.’ In other words, Reiki is spiritually guided life force energy. We can see that this operates very similarly to the practice of yoga and acupuncture, which both refer to ‘prana’ and ‘chi’ respectively and work by improving the flow of energy throughout the body. Even sound healing operates on a similar principle. That is not to say that you have to believe in god for Reiki to be effective – it will work whether you believe in God or not. However, it may put you in touch with your true self.
