Always interested in hearing about experiences at different teacher training.
While I wasn’t there so wont speak to the cultish ‘vibe’ and that part of your post was informative.
However I think you may have oversold some of the other ‘brainwashing’ efforts.
7 hours sleep is not all that little especially during an intensive workshop or teacher training course, or even life. It may be less than ideal for many who need the 8 or more hours sleep for optimal performance and regeneration but it certainly falls short of sleep deprivation for purposes of brainwashing.
I went to a ‘modern’ school including an intensive retreat and we were practicing by 5:30am or earlier and yes to fulfil the hours of practice in a short intensive most TTC will be pushing late in the evening.
Modern teachers like Bryan Kest highly recommend the full emersion technique. “A training of this nature has to be an immersion. Regardless of whether it is two weeks,… six months or longer; however long one needs to get a taste of it, to feel it. It shouldn?t be just an intellectual concept, it should be an experience.”
I don’t want to push you to open up more about your experience if it is painful to you. I do think hearing points of view may help others make their best choice at least more informative.
