I think you need to contact TMI about that. But my take on it is: No.

The question is what program you talk about?

   They don't "hypnotize" you per se, but i have recently revisited the In Home Gateway series, and noticed a couple minor/brief positive suggestions that Bob gives.  And because you are in a more relaxed state, you may be more open to such suggestions or they may influence you more.

Since they are in line with what one would conceivably want to achieve with experimenting with such a program to begin with, (otherwise, why even try it), then i see it as perfectly ok, wise, ethical, and probably helpful. 

  It's not like going to a hypnotherapist though.

Hi Claudio

We had an outreach program here (in Massachusetts) in ...2009?  Facilitator was Andrea Berger, who was just starting out. Her goal was to take programs to her native Romania, which I think she has now accomplished.

This must be the person who is presenting the workshop your reader is interested in:

Yeah Justin is correct, there is positive reinforcement but...nobody is going to be asked to imitate a duck! I personally dislike guided meditation so I sympathize with your reader, but there is nothing to fear in what they do. After all, a trance ias a trance, and when we sit glued to the tv the commercials can do a pretty good job of "hypnotizing" us! So they use the recordings made at TMI, so if you  have used those then you know a bit of what the excursions are like. Is that hypnotizing people?

Would be interested to hear how your reader enjoys (or does not enjoy ) the program.
