I just purchased the Baguazhang instructional DVD and I have noticed some deviations from the qigong forms shown in the book. #5 The Spiral and Rotate Posture, the DVD seems to be skipping the 4th step the book shows and as well as an additional turn.
The biggest deviation however is #6 Twist Turning Posture. In the book it is shown that when turning to the left the left arm twists up, the right moves down and visa verse for the other side. In the DVD though the arm positions are switched and the rear foot's heal is lifted. After switching between these the form in the book and the one on the DVD I've determined the on shown in the book feels more correct and leads easily to the bore and turn posture(or arcing and swinging walking). When trying to transition to another posture or form from the one shown on DVD you would have to take an extra step and change the arm positions.
Perhaps I am not grasping the use of this deviation. If anyone has noticed these deviations or has an idea of how it can help differently with either qigong or an additional transition please reply!!
