Reiki in Japanese means universal life force. In Japan it is believed this energy is channelled by the practitioner to the client by a gentle laying on of hands. The client then uses this energy for healing mind body and spirit.
Reiki is a safe, gentle non-intrusive hands-on healing technique that may accelerate physical healing, balance the emotions and encourage positive spiritual and physical change. Reiki may also work to build immunity in the body to prevent illness and fatigue or stress.
Karuna is a sanskrit word and is used in Hinduism, Buddhism and Zen. It is translated to mean any action that is taken to diminish the suffering of others and could also be translated as "compassionate action".
Karuna reiki evolved out of Usui and Tibetan reiki from a desire and a knowingness that there is always something greater to be uncovered. No matter how wonderful something is there can always the next step, the next lesson, the next development.
