Practicing Reiki through self-treatments helps to process and sustain the positive changes that an attunement to Reiki promises. When you are ill, self-treatments will help bring you back to good health. When you are healthy, self-treatments will reinforce your vitality and strengthen your immune system. Giving a Reiki self-treatment is easy — all you need are your hands, your body, and a willingness to heal and be healed.
