Massage, energy-sharing, chiropractic medicine, acupuncture and acupressure, yoga, and other disciplines of body manipulation allow a person to influence mental and physical health, stimulate organic functions, establish or reinforce intimate bonds between the practitioner and his subject, and simply help people feel better about themselves. As a result, bodywork forms a centerpiece for several mystic practices, especially ones that – like martial arts, shamanism, witchcraft, yoga, and certain types of medicine work – favor vitality over external tools.
