Reiki practitioners must receive an “attunement” by a certified Reiki Master Teacher. This attunement “tunes” the practitioner to Reiki energy. During the attunement, the Reiki Master Teacher opens the chakras and tunes the practitioner’s hands, so that Reiki energy can flow freely through them. Clients often experience a sense of heat or tingling. The Reiki practitioner can now flow Reiki through their hands for the benefit of others and themselves. Reiki practitioners do not generally feel drained while providing energy work that can happen with other forms of energy healing.
