Have not read the book, but the review indicates that she offers good advice on standing/sitting, how to properly align your body to help release the pains your mind has created in your body. Sarno and others have written that although these things we do with our bodies (sitting correctly/physical therapy/massage/resting on a good mattress, etc) may not hurt us that the real change is when we realize that these 'things' are not what is creating our pain, but our thoughts/brain that is maintaining these symptoms. This was an epiphany for Dr. Sarno and when he came to this conclusion he stopped ordering physical therapy for his patients, but just had them listen to his lectures/read his book, etc. The patients recovered well without the body adjustments or other physical manipulations.
