spiritual attunement, keep me sane on days when I am drawing in too much neg from the world and my inner thoughts. It aids me in coming to center in a quick and effortless way. I always feel it first in the Tan Dien (sp) the vortex of energy just below the navel. Also known as the gate of heaven if I remember correctly.

Spiritual Attunment is one of our heavy hitters... a good long time performer, your Dan Tien explanation seems bang on... Ive had a few other people report similiar types of effects, I find it always to be a real grounding, calming, soothing trip
