Surprisingly effective quick summary of NLP; only a faint hint of whalesong, and that was limited mainly to the chapters on spirituality and belief. The rest of the book is a direct and focused tour of NLP techniques and "presuppositions". Slightly weak on the "Linguistic" aspect of NLP, and frankly the "Neuro" part is almost completely missing, but that could well be a weakness of the discipline rather than the book. Informative. ( )
