When I first moved into the ashram I lived in a tent for the summer. The fellow living in the tent next to me asked me if I'd like to do Dynamic Meditation. I thought, "Gee, I like meditation so if it's dynamic, all the better!"
Ten minutes later we were off in a corner of the campground next to the woods with a boombox blasting drum and synthesizer, shaking and jumping and hooting. I didn't get the connection until the movement ended and I dropped into a profound stillness.
Since then I've led countless practitioners into the experience. Rather than go into the details of it, here's a rather silly video I made explaining some of the details.
I'll be leading a daylong retreat this Saturday. More information here.
