Xue Sheng
All weight is underside
I felt this was applicable to what has been going on in this post. It is a quote from Wang Ji Wu (1891 – 1991) who was a long time Xingyi practitioner who was highly respected.
All practice starts with San Ti standing. After walking through the forms, one must follow correct sequence of training and must not omit a step. All subsequent movement is founded in San Ti Shi. This posture is the gate of the Way, it is the root and the central nucleus of the art of Xing Yi Quan – Wang Ji Wu
