Susan Matthews, head of the Shanti School of Tai Ji, demonstrates one of the most famous of Qigong forms: The Eight Pieces of Brocade. She does this standing in front of a mirror so we get the benefit of a double view of each action. Her instruction is detailed but also has the informality of personal observations, how she felt a certain move, how she solves a problem in exection. Her instruction is clear and detailed. This is a very good approach to learning this 800 year old, treasured set even if you are trying for the first time.
