That is what in my opinion separate a REAL master by the common martial arts pratictioner, the ability to assimilate and remember a huge ammount of technical information and being able to pass them on.
When you said somewhere that to learn martial arts you need also to be "smart" couldn't be more true.
I guess all those Thai boxers and western boxers and those that train in systems that have only a handfull of kata wil never be true masters.
Psalms 144:1
Praise be my Lord my Rock,
He trains my hands for war, my fingers for battle !
