Energy healing is a general term for modalities that are based on the idea that the human body consists of energy fields that can be stimulated through various techniques in order to promote wellness. The concept of energy fields as a vital life force can be traced back to the oldest medical systems and is known as Qi in China, ki in Japan, and prana in India. The underlying basis of all of these modalities is the idea of energy flow in the body. Practitioners of these modalities believe that keeping the body's energy in a balanced state is the key to maintaining health. In each of these modalities, the practitioner seeks to help the patient rebalance energy in the body, by stimulating, unblocking, or dispersing it. The result is a greater sense of energy and well being.
