Reiki is an ancient practice from Japan which relaxes the mind, body, and increases feelings of peacefulness, balance and connections to wholeness.
Reiki is not a massage. It is done with clients fully clothed, though shoes are removed for grounding work. Most sessions are done with clients face up on a massage table or sitting in a chair if needed.
Reiki practitioners often use hands on and off methods. A hands off approach is referred to as working in the aura or energy body and is equally effective.
