Some excellent points.
As mentioned before, the Byron Katie "head-cock" or her tilting of her head at times, is not just a random thing, believe it or not. Sure, it may have evolved organically, but its a technique too.
In hypnosis, they establish "signals" and triggers and anchors.
It may be a hand gesture, or a look, or a head-tilt, Voice-Cue, anything.
You see, over time, they are able to set up a signal system with the subjects..(you), and your unconscious knows that right after the head-tilt, some powerful Suggestions are coming.
You will see Byron Katie talk...then pause, think...tilt her head in a head-cock, and then deliver some powerful suggestions.
Milton Erickson did Voice-Cues, and there are many methods like this. NLP has Anchoring, similar thing.
Yes, these are very skilled and talented people, its how they use those skills is what counts. Ethics.
Hiding their technique to such an extreme like Byron Katie, is deception, and is profoundly unethical.
Also, the NLP books, The Structure of Magic I-II, are interesting books, have them right here, and there are up on the torrent networks too.
Book I is a careful analysis of Therapy, and the Language patterns of some great therapists, like Virginia Satir, Milton Erickson, etc. Its great stuff, but not an easy read.
They took the invisible MAGIC of what those folks were doing, and explained its STRUCTURE.
(same thing we are doing with Byron Katie...its not BK Magic, its Technique)
Its clear this is woven into the fabric of what Byron Katie does. She is doing a type of therapy on people, certainly not cognitive, but a type of hypnotherapy and psychotherapy, which is being misused on people without their awareness of what is happening to them.
On top of all that are the dozens of LGAT and sales techniques of social engineering.
Its abusive and people are being exploited financially and emotionally.
In this modern world of cost and profit, there may be a compensatory and yearning for magic, for instant transformation, for some Magic Parent who will come along, and who, with a charming smile, gives a charming sparkle of the eyes, an ever so charming tilt of the head, and with makes that pain instantly go away.
It is noteworthy (Anticult can help us here) that one of the early NLP books was entitled The Structure of Magic.
