"Reiki Plain and Simple - A Guide to Reiki Ryoho" is an e-book written by Vincent Amador. You can access it in its entirety at home.zonnet.nl. It is divided into three sections, with the first section divided into three levels.
"Reiki Plain and Simple" describes a hands-on healing practice "rediscovered" in the 1800s by Mikao Usai, a Japanese Christian minister. Mr. Usai trained 18 students, who became Reiki masters. Reiki Master Hawayo Takata brought Reiki to the United States just before World War II. Masters teach Reiki in three sections or degrees, with the student undergoing attunements as training advances. Upon completion of the third degree, the student becomes a master and may teach Reiki and give attunements to others.
