Historical background
Basically Reiki is an Indian technique of touch-healing that was being practiced in the southern part of India. During 500 BC, Shakya Muni used to touch the sufferers. Through him this healing system went to Tibet and form there to the lost continent of Atlanta. It is believed that Reiki was lost to world when Atlantis sank into the sea after a catastrophe.
The touch-healing system was also known to have been practiced by Jesus Christ and other saints. It remained dormant for a few centuries thereafter.
Subsequently, in the 19th century, Dr. Mikayo Usui of koyoto city of Japan who was working as a teacher in a university, meditated for 21 long days on top of Mt. Kurama. Thereafter he got saturi (self-realization) and acquired the power of touch-healing.
This healing system was continued by Dr. Chijiro Hayashi and subsequently by Mrs. Hawayo Takata of the USA. Today, this healing system is very popular around the world and several lakhs of Reiki practitioners and masters exist in various countries.
