Reiki is a Japanese technique by laying on hands to deliver energy to the body and improving the flow and balance that promotes healing.  The most common experience is an almost immediate release of stress and a feeling of deep relaxation which can be felt right away and may last for a few days.
 

Mikao Usui developed reiki in the early 1900s, deriving the term from the Japanese words REI meaning universal, and KI which refers to the vital life force energy that flows through all living things.  It is used all over the world and is sometimes referred to as Healing Hands.  ​
