I tried to look up more info about it but it seems like to learn anything, one has to take some $1500 course. Can you summarize how it differs from the standard meditation (i.e. zen meditation)?
Zen meditation isn't really "the standard meditation", American culture just has an infatuation with Zen because the Beats and Hippies drew a lot of attention to the San Francisco Zen Center at the right time, while otherwise Buddhism and Hinduism have mostly stayed in immigrant communities. (I don't know enough about the Hare Krishnas to say anything either way.)
Zen meditation is a japanese adaptation of the chinese adapation of the Raja Yoga techniques of Hinduism/Buddhism.
