One of our students recently spoke of how he has come across former students who still think of Sifu, the class and the art. They have an air of incompletess to them. Some still practice what they think they remember. Others now see themselves as being instructors.
Isn't it odd how the art takes a hold of you?
The student suggested that people are 'haunted' by their memories of the art. The massive amount of effort, time and money expended in learning taijiquan meant that years may have been committed to something that was at some stage cast aside.
