I am on chapter 4 of this book. I have read a couple by Sarno (healing back pain and the MindBody prescription) and two other books, and liked them all, but this one really speaks to me. I have a research nackground (genetics and psychology / psychiatry with a fair bit of neurology thrown in for good measure) and I feel this gets to the lingering questions I have and reframes some of the things I read in Sarno in a way that makes more sense to me. I have the five chapter version borrowed on Amazon prime and will definitely be purchasing the complete book. Can anyone tell me how the program compares with the SEP? Thanks.
