Definition - What does Reiki mean?
Reiki is a form of alternative energy therapy developed in 1922 by Mikao Usui of Japan. It is a form of hands-on healing therapy that combines the use of touch and energy channeling to promote a sense of deep relaxation and healing. The aim of Reiki is to clear the body of energetic blocks, allowing the energy to flow freely and for balance to be restored.
Reiki is a Japanese term that may be translated to mean "universal life/energy." It is a combination of rei, meaning "universal life," and and ki, meaning "energy." Ki can be viewed as synonymous to chi, prana or cosmic energy.
Yogapedia explains Reiki
Much like the flow of prana, the flow of ki determines the level of one's health. A balanced energetic flow of ki keeps a person healthy, while a disrupted energy flow can adversely affect physical health and mental well-being. By clearing energetic blocks, ki energy can flow properly through all the channels of the body.
Reiki therapy allows ki energy from the hands of the therapist to flow to the person needing healing. Hand positions are used on or above the recipient's body. The best way to optimize energy flow is by lying down while the energy is being given by the practitioner. Reiki can also be received while standing, sitting or even remotely, as distance healing is also possible.
