"It would be hard for me to write this preface without my own feeling of excitement, amazement and thrill coming through. What Richard Bandler and John Grinder have done is to watch the process of change over time and distill from it the patterns of 'how' process. They seem to have come up with a description of the predictable elements in a transaction between two people that make change happen. Knowing what these are makes it possible to use these consciously and have useful methods for inducing change. Now the knowledge of the process of change is considerably advanced." - Virgina Satir, International teacher of Family Therapy, author of Peoplemaking and Conjoint Family Therapy.
