“Pak Sao doesn’t look like much yet every essential attribute and principle can be explored via Pak Sao. The worst thing you can do is to interpret Pak Sao as some sort of combative drill i.e. “blocking punches”. Pak Sao is essentially a physical discussion of centerline, energy, and hand replacement. The key to gaining anything out of the Pak Sao exercise is to understand it in this context. To perform the exercise in a perfunctory manner while thinking about what comes next is a waste of time. This is true for all the exercises leading up to Chi-Sao.
If you cannot teach someone Pak Sao beyond the physical choreography then you do not understand the drill. If at any stage in your training you cannot explain what you are doing and why you are doing it then by definition you do not know what you are doing.”
