I strongly recommend this book of great wealth. "Metaphors" is for all those and all those interested in hypnosis and NLP .... The book gives an opportunity to review some basic concepts and offers valuable tools to cause the change. It also provides clear answers to people who have questions about what the "Humanist Hypnosis". Very good read.
PS: For information (for those of you who might think ...), I knew that O. Lockert name and had previously read any of his works ...
