Here's another techtalk, again by Shinzen Young: http://www.youtube.com/watch?v=8XCWP4pODbs The technique is called Vipassana meditation, according to his website.

I've been doing zazen for a little less than a month. Zazen is a little different from vipassana(with wich i have even less experience than with zazen, as i said, less than a month). I chose zazen mainly because it sounds so simple: sit with your spine straight up(in the lottos position if possible, im not there yet, im too inflexible) breathe normally and count your breaths for 10 minutes every day, no magic Indian mysticism involved, which is what threw me off Buddhism the first time i encountered it.
