I spent 5 days with Paul Grilley in another wonderful yin yoga teacher training. this video was taken by Zach, who came from Michigan to the Chicago Yoga Center.
Paul is talking about being a courteous student if you are in a workshop or a class and you do not agree with what is being taught.
I have studied with Paul for 5 years now and what I love about him is that he kills the yoga sacred cow of "universal principles of alignment." I will write soon about my experience in his training and post my own pictures.
