Medical and Spiritual Qigong (Chi Kung)
I trained with Bryn orr on and off for about 2 years and I can assure you that the simplistic view you found him to have, is so that the information can be understood. But, rest assured, if you feel that you need complex explanations, he (in my opinion) has the best knowledge of martial applications/Qi gong/meridians/history etc out of anyone I know by a long shot. I think a great teacher can make a complex subject simple and be able to be understood by the person learning the material. For what it is worth, I would recommend any material written by Bryn Orr and if you get the opportunity, one on one tuition or any seminars that he is holding.
