The beauty of Reiki is its simplicity. Anyone can learn to use Reiki, including children. Reiki is not a cult or religion, so it may benefit anyone regardless of beliefs. The only way to acquire Reiki is through attunements, carried out by a traditional Reiki Master.
Once attuned to Reiki, you can treat both yourself and others with this gentle, yet profound energy. During a Reiki treatment the hands are placed lightly on the body and remain still in different positions.
The great advantage of Reiki is the easy way for everybody to practice self-treatments.
