REIKI
When I was given my notes on Reiki I found a lot of emphasis on Dr. Usui rather than on the healing art itself. When I began to teach Reiki I found these notes lacking in many aspects. If you were to make a comparison of the notes I have written and those I was given - the difference would be that I received high school understanding whereas I am providing a university education. I had very little in the way of actual notes and have expanded greatly on them and filled in the many holes I found in order to give students a fuller understanding and a better education. I want my students to have a more rounded view of Reiki rather than a narrow one so that they are better able to apply their teachings - both to themselves and for their clients.
In my dealings with students and from personal experience I have found that each level corresponds to a different level of development. Of course these are just my own observations but so far everything seems to collaborate what I have observed.
