what are the origins of reiki?

Reiki, goes back to the early 1900’s.  A Japanese man named Mikao Usui “discovered” Reiki after 21 days of fasting and meditation on Mt. Kurama. He received the symbols and the system that became Reiki just before leaving the mountain on the 21st day.  He then began healing and teaching.  Reiki spread throughout Japan and was introduced into the United States via Hawaii by a woman named Hawayo Takata, who set up the first U.S. Reiki clinic in 1937 and helped formalize the system.
