Not entirely relevant to this conversation, but:
there at least used to be regular vipassana meditation sessions led by monks from Abhayagiri and hosted at the Berkeley Zen Center (I think that’s what it’s called) on MLK near the Ashby BART station. Abhayagiri is a monastery in the Thai Forest tradition led, I believe, by a former student of the late Ajahn Chah; in my experience that’s usually a pretty good indicator of a very result-oriented approach to meditation that eschews the supernatural talk in favor of the pursuit of practical goals (though in their case the ‘practical goal’ is enlightenment, so take that as you will).
I believe it’s actually right down the street from the Thai Temple. Much less official looking. I haven’t actually been though (always intended to go, and then ended up moving away before I did).
