This is a very good book and the core of it is valuable and amazing, however there are some flaws in the kinesiological method and results, and some annoying generalizations 'metal music makes one go weak' without saying what specific music was being tested. When doing kinesiological or energy testing, one must be very specific about the subject of the test. Also, one's personal feelings and mentation can at times override proper testing (this is why he says one has to be at '300' or above to get proper results). Dr. Hawkins has done us a great service with his research however, and seems to be very sincere. The levels of consciousness diagram is worth the price of admission.
