If you think you have great sensitivity, try practicing blindfolded. Even if these are good tests, to use all of these skills in combat are also a different matter. All in all, it's not about words or lip service or style, theories or techniques, lineage or secrets. Lineage or style can only tell where your basics are from, but not necessarily what your cultivation is today. In my opinion, too many people place too much stock in that, your art is not where the base information is from, but how you have cultivated it now.
Cultivation is everything.
All is good if you cultivate it. There is no one true form. Recordings are only recordings of that moment in time, of what a person knows and understand at that moment. As we are always changing and growing, we can always cultivate and grow more. I am no guru or master, or anyone important, so I don't have all the answers to everything.
