All good points, Xue Sheng, East Winds and Pete.
I'll study the 10 essences -- thanks for the links, Xue Sheng.
Pete, I agree with your interpretation, with an addition: In most TTCS classes that I have seen or heard about from other students, they are not trying to have it both ways, because they are not
capable of doing so. In fact, unless an instructor has had direct experience with a teacher who has the skill (and permission) to innovate and give individually-tailored instruction, he/she is not
aware such instruction ever existed. Any instruction given to a student is assumed to apply to the entire class.
East Winds, I agree with your assessment of the TTCS. I can't say when it came to that state, but I like to believe that at the very beginning in the 1970's, Mr. Moy's goal was as I stated. It's hard to say how much of his ideas remain with the TTCS, and how those ideas relate to its current policy. We may never know ... but it doesn't really matter to those of us outside the TTCS, I suppose.
Thanks, all.
