Of course they did. This shit has been done and done over and then perfected and done again. Trial and error my friends - of course they knew. We were mere rats in cages to the mon$ter$.
"est adopted, in part, the Zen master approach, which was often abusive, profane, demeaning, and authoritarian. (One of my favorite Zen stories is of the master who asks his disciple a series of questions. No matter what the disciple answers, the master hits him with a stick. Even contradictory answers are met with the stick.) While many participants did not perceive the training as particularly abusive, some were not used to the discipline requested of them. Some have claimed that one typically abusive approach was the requirement of extraordinary bladder control in est training. Participants were advised not to leave the room, even to go to the toilet, during training. According to one est participant, however, "bathroom breaks were scheduled at regular and reasonable intervals....Two or three rows at the back of the room were reserved for those who required more frequent bathroom breaks (and I think either some sort of documentation or personal insistence were required to qualify). No one was ever physically required to stay in the room at any time" (personal correspondence). (This aspect of est training was humorously ridiculed in the movie "Semi-Tough" (1978) with Burt Reynolds and Kris Kristoferson.) In any case, one should expect some sort of discipline and required order for this kind of training. Having people come and go as they please is distracting and not conducive to the concentration necessary for such a program."
