While reminiscing about the past and history is, by itself, a worthwhile endeavour...
What real purpose is served by dwelling on who did what and when?
Does it matter to your everyday practice if Chan San Feng was the originator of TCC? Does it matter who learned which portion of TCC when or where two or three hundred, or a thousand, years ago?
If your instructor knows his TCC, and he's teaching you in good faith, and you're practicing regularly and applying martially...
That's what's truly important.
My current instructor has a real grasp on TCC. He knows his stuff, better, much better, than I do when it comes to the martial apps. He has been taking the time to show me the gaps in my martial knowledge. He has been taking the time to then show me in the form where this or that technique is best performed so that I can take that technique, add it to my "intent" in form training and thus improve both.
I think it's really very cool to know at least the general outline of who invented TCC, who passed it on, where it came from, what they did. Don't get me wrong I've been caught up in the eternal debate before myself.
What I'm trying to say is...
It makes no difference to me, truly, who invented TCC, who passed it on to who, when or where. As long as MY instructors are genuine in their knowledge and are sincere in their wish to pass that knowledge on to me.
You will know, hopefully much sooner than I did, whether or not your instructor is passing on genuine TCC knowledge, or is milking you for a paycheck.
That's what matters now, today.
