The Bars never existed on earth before they were channeled by Gary M. Douglas. While the points may appear to be cranial-sacral or acupuncture points, they have a different function when done as part of the Bars. We have not seen any other method generate the changes that are created by the Bars.
Reiki practitioners tend to do very well at learning the Bars since they are already familiar with energy. The Bars and doing the Bars for others seem to have a more wide-ranging effect on the whole lives of the people doing the Bars than Reiki practitioners seem to experience.
