Karuna Reiki® is a system of Reiki that focuses on compassionate action and healing, developed by William Lee Rand at the International Center for Reiki Training (ICRT). It builds upon Usui Reiki, incorporating additional symbols, attunements, and techniques to facilitate deeper healing on emotional, mental, and spiritual levels. The word "Karuna" is of Sanskrit origin, meaning "compassion" or "action taken to diminish the suffering of others", www.reiki.org
