If you ever wanted to learn NLP or hypnosis then this is the center of the vortex. Everything about modern persuasion goes back to the unassuming Milton Erickson. Everyone from Richard Bandler to Tony Robbins owes a great debt to him. This and the second volume is the definitive guide to hypnosis. What out though it is not an ordinary book. It is for doctors as such. Meaning that if you haven't come across the topic of hypnosis then read up on it before getting this book. Very technical. Saying that, that means that this is where you learn the heart and soul of hypnosis. It is not step by step for getting people into hypnosis it is the understanding of hypnosis, which leads to a better hypnotist.
