I have to say, having to buy the book (no independent description or studies of the process) and $200 seminars (indoctrination) sets off my "woo" alarm. As does anything mentioning "NLP".
I'm just describing my own path through the material, which started with curiosity, a few google searches, investing $15 for a dead tree book, and after about a year of practice, trying out a one-day seminar (for which, as I mentioned, my results were pretty '-meh-').
And what's woo about Natural Language Processing? ;)
