Reiki

 Reiki comes from the Japanese word’s rei, which means “universal life,” and 'ki" which  means “energy.” Reiki was developed in Japan the early 20th century by  Mikao Usui of Kyoto. It's not part of any type of religion or belief  system. To this day it is the safest, least expensive and largely  researched method of treatment that aids in the healing of many  illnesses. Reiki is a non-invasive, non-manipulative therapy that  involves a practitioner using gentle hand movements to guide energy  within a person's body. 

Reiki practitioners believe that there is an energy force in and around the  body, and that a person's energy levels affect their health. They aim to  change and balance the "energy fields" in and around the body to help  it release energy flows and heal itself. During a reiki session, the  practitioner places their hands lightly on or over the client's body,  typically keeping their hands in each position for around 3 minutes. The session usually lasts for approximately one hour.
