Okinawan Fighting Art "Ti"

I was reading the Kowakan blog this morning and came across the following quote by Mario McKenna Sensei alias Bechurin. It speaks toward another way of viewing a "traditional or classical" form of martial system.

"Its my own opinion that the only real “tradition” found in Okinawa Karatedo is the tradition of change. Each subsequent generation adds, eliminates, or modifies the tradition they inherit from their teacher(s).  ...  Kowakan Blog by Bechurin "Change is Inevitable but when & how are everything."

I find this to be interesting and solid in theory. It actually speaks well toward the obvious when you start to take a closer look at the systems and their evolutions through the times and practitioners who became the new masters as the old ones passed to the great dojo. Read the two links above and consider the truth to McKenna Sensei's words, "So what do you think you were practicing?"

Speaking for Isshinryu as a practitioner and not an authority I find the historical information, note I didn't say facts, that Tatsuo-san was always changing things and he often did kata different, i.e. slight differences but different. This would support this hypothesis of McKenna Sensei, yes?

Let me add as a sort of addendum that my research on culture and beliefs of Japanese, Okinawan and Chinese is that often they took what was best of other things of interest to them and made them into something unique to their particular cultures and beliefs. I found too many connections and similarities in all three from my studies that I have come to believe this as true and correct.

It begs the question, "Why do westerners feel strongly that our practice MUST be EXACTLY as the system master taught?" Is it to feel that connection to a large entity and does it reflect our instincts for survival, i.e. attach ourselves to a like-minded group for greater strength and survival, etc.? Is is to feel connected to something as McKenna Sensei states in his post?

Thanks to McKenna Sensei for the inspiration and information - great!
