I agree with Jenn regarding Essential Reiki. However, I recently received an email from a new Reiki author, Jacqueline Chin. She wrote:I would like to announce the availability of my new book The Light Within. What makes this book different from all the others written on the subject? I looked around at what others had written and found that there was nothing based on a historical perspective of the actual time frame in which Mikao Usui lived. Writing from the perspective that to fully understand where one is going in life one has to understand where they came from I began a 4 1/2 year endeavor to accomplish this task. ย Reiki practitioners will not find new Reiki secret symbols or hidden secrets within this text, but they will find a firmer foundation on which to base their practice. ย It is my intention to bring Reiki full circle back to its original roots. ย I do so hope that you will enjoy adding The Light Within to your Reiki book collection.(I have chosen not to include the full text as it is long)She continues:There is much speculation regarding Mikao Usui the life he lived and the healing method that he developed. Where did he grow up? What was his education? Who were his teachers? What were his beliefs? Why was he so interested in healing? How did he actually come about the first experience of Reiki? These are just a few of the questions that will help to define who Mikao Usui was and give the reader a better foundation of the founder. It is the writers intention to dispel erroneous beliefs concerning Reiki's fundamental origins.You can find The Light Within at http://www.authorhouse.com , or ask for it at your favorite on line bookstore. ย Thank you for your interest. Interest and comment can be addressed to this e-mail Tilung8@aol.comI haven't ordered it or read it. I do not know the author. This is not a promotional post. I just received this email 2 days ago and thought the timing was interesting.If you decide to get it, I would be interested in your thoughts on it.Sally
