After extensive research, this, to my knowledge, is the most accurate Yogi Bhajan approved version of Sobagh Kriya that exists. *Please note that you'll see this kriya called SU-bagh Kriya all over the internet. YB called it SO-bagh Kriya several times and even spelled it out at the end of the lecture.
