Reiki is an energetic/spiritual healing modality. It will support your body in regaining balance on every level - mental, emotional, spiritual and physical. Using a light touch with hands on or just above the body, Reiki will quickly relieve stress and promote deep relaxation. In this relaxed state all systems begin to normalize and balance themselves. Reiki also benefits us by improving sleep, digestion, respiration. It gives us a sense of groundedness, increases motivation, lessens the side effects of medications. Reiki supports the natural healing process of our body, mind and spirit.
