Reiki is a form of energy healing. Founded in the early 20th century by Mikao Usui, a Japanese Buddhist, it is known as Usui Shiki Ryoho Reiki. It is a practice of healing through hand placements on the body. Reiki means the unification of universal and vital life energy. Achieving this connection can bring a sensation of inner peace. A complete Reiki lifestyle can lead to 'Anshin Ritsumei', the ability to experience inner peace amidst external chaos.
