Karuna is a Sanskrit word translanted to mean any action that is taken to diminish the suffering of others and could also be translated as "compassionate action."
Karuna Reiki® is a development from Usui Reiki, and feels similar though undeniably different. Some would say it is a higher or more powerful energy. It can also incorporate the use of specific toning and chants (though these may be silent).
Karuna Reiki® was developed through William Lee Rand of the International Centre for Reiki Training in 1994 and is generally only taught to Reiki Master Teachers, due to its powerful nature.
Karuna is the motivating quality of all enlightened beings who are working to end suffering on Earth. Experiencing and working with Karuna Reiki® opens you to work more consciously with enlightened beings who are physically present as well as those in spirit.
