The book pretty much explains in simplistic terms what the accompanying CD delivers. At first i had to get use to the man's voice as its not that masculine, but once i over came that and got use to it, (because voices are important to guided meditation personally i cannot stand Paul Mckenna) I found this to be one of the best books/Cd's on meditation, its simple and it delivers, even if you just listen to the CD. I use it before i go to bed, i haven't listened to tracks 5 and 6, but i find 1-4 very useful in the art of quieting the mind which really does help with pain, emotions, obsessive thoughts (which usually occur before going a bed, you know when you want to sleep and your mind decides to switch itself on!). In conclusion, its simplistic, ideal to fit into your schedule as the meditations stem anywhere from 8 to 14 minutes all of which seem to fly by, but deliver because they leave you feeling very relaxed with a calm state of mind. I recommend journalling and to do lists for the next day before you go to bed too as a way to help empty the mind.
