Reiki is an alternative medicine method that has been developed in 1922 by the Japanese Buddhist Mikao Usui. The traditional form of Reiki that Usui has developed has been adapted into many cultural traditions across the world. Reiki uses the hands-on healing principle, where the energy is channeled through the palms of the practitioner to the patient in order to aid the natural healing process on all levels: emotional, spiritual, mental and physical.
