Reiki is primarily a hands-on technique for stress reduction. Reiki engages the parasympathetic nervous system. A practitioner uses hand positions on themselves daily to promote positive well-being. This personal practice extends to providing Reiki to other people, animals, and plants. It can remain a private practice for family and friends, or it can be offered professionally, usually after completing level two or above. It is easily integrated into other modalities and clinical settings. Reiki is easy to learn and accessible to everyone.
