When planning her first Reiki classes, Maureen Kelly analyzed the content and the different teaching methods she encountered while progressing through the Reiki levels. She decided to write a manual for each of the classes, which ultimately forms the basic outline of this guide. The descriptions of the Reiki classes are based upon the oral traditions of Reiki that were originally taught by Mrs Hawayo Takata. The practice of Reiki has changed and evolved since it was first brought to the west; therefore, the descriptions are a version of Mrs Takata?s teachings, not exactly what she taught. It is not a complete work as Reiki is beyond being confined to one way or practice and is far greater than what can be encompassed by one person.
