Reiki is a Japanese word translated as "Universal Life Energy" by Hawayo Takata. She brought the possibility of a relationship with this energy to us through Usui Shiki Ryoho, a healing system founded by Mikao Usui in the early part of the 1900's. I received my Reiki Master training in the 1980's from Dr. Jo Davis in the Kansas City Missouri area (Blue Springs). We are in the direct lineage of Mrs. Takata. Mrs. Takata brought Reiki from Japan to the West in 1938. Until 1982, Reiki was an oral tradition in the West with no written record of its history of teachings. Until recently, all current information about the history Reiki has come to us through the spoken word of Mrs. Takata.
Reiki is a therapy often described as palm healing or hands-on-body healing in which a practitioner places hands lightly on or over a patient's body to facilitate the patient's process of healing. Reiki combines the Japanese and Chinese word-characters of "rei" (spiritual or supernatural) and "ki" (vital energy).
One of the greatest Reiki healing health benefits is stress reduction and relaxation, which triggers the body's natural healing abilities (immune system), aids in better sleep and improves and maintains health. Reiki also balances the mind and emotions.
