Reiki is a specific form of energy healing developed in Japan, based on the belief that a practitioner can channel universal life energy through their hands to help clear blockages and restore balance in a person's energetic field. Unlike some energy healing methods, Reiki follows a fairly structured system, with practitioners trained and certified through recognized levels, often called degrees, before they can practice or teach it.

A Reiki session typically involves the practitioner placing their hands lightly on or just above different areas of the body, moving through a set sequence, while the client simply relaxes and receives the energy work.
