This book grew out of a desire to provide Professional Members and Outreach Trainers of The Monroe Institute with a guide of sorts - something that could be grabbed on the run in order to find out what exercise went with what real-life application. I also wanted a place to put all the feedback that had been reported in the Hemi-Sync Toolkits about various real-life applications of Hemi-Sync, and possibly some of the other feedback reported in the various journals. The information from the Toolkits forms the substance of Part I of this book. Following each section, I have added a list of the Hemi-Sync Exercises that relate to the particular application - the list is up to date with the 2015 catalog. Part 2 is a reverse reference. There I have listed every Hemi-Sync product, given the basic information about the CD, and then noted all the applications where that particular item has been found to be helpful. Part 3 contains some feedback reported in the early journals produced by TMI - going back to 1983. I found it interesting to see some of the early reports of the uses of both the Metamusic and the H-Plus programs that were being developed.
