At age 57, Usui Mikao Sensei-founder of Reiki Ryoho-received the Reiki system of natural healing in 1922 after 21 days of fasting and meditating on Mt.Kurama in Kyoto. See www.ReikiCenterofVenice.com for more information on Usui Reiki.
In Japan, Reiki means the following:
"Rei" means mysterious, universal, miraculous, sacred.
"Ki" means energy, atmosphere, something unseen.
Together, the words "Reiki" can be definied as a sacred and miraculous energy which sustains all life. To me, I call it "Universal Life Force Energy".
In Japan, the word 'Komyo' is translated as meaning 'Enlightenment'. Thus, the name Komyo Reiki itself can be translated as meaning, "Enlightenment Reiki".
