Karuna is a Sanscrit word which means "compassionate action." The Karuna Reiki® method was developed by William Lee Rand and others at the International Center for Reiki Training. The Karuna Reiki® practitioner has access to stronger, higher frequencies of healing energy that bring about a greater potential for healing.
In terms of treatment, you won't notice a difference in anything the Reiki practitioner does. You'll still lay comfortably on a massage table under blankets and feel deeply relaxed. The practitioner will continue to use a series of gentle hand placements along various parts of the body to deliver the energy. The only thing that is different is the frequency of the energy being channeled.
What's that you hear? Your practitioner is toning or chanting some indecipherable syllables? Well, yes, that is part of the Karuna Reiki® system, but most practitioners, if they do tone or chant, will do it silently, inside their heads. Not to worry if yours feels the urge to do so aloud. It's just another way of calling forth the higher frequencies of the Karuna Reiki® energy. Hey, if your practitioner has a good voice, she may even lull you to sleep with her chanting!
If you have reached the ART level, and have been at that level for at least 6 months, you can study and become attuned to Karuna Reiki®. Honestly, I would highly recommend studying Karuna Reiki® with the man himself, William Lee Rand. But if location, time, and/or place is inconvenient for you, you can see my full schedule of Karuna Reiki® classes here.
