i try never to say that anyone else's training is wrong..though i do have opinions that i sometimes express based on goals and purposes.
when i started my training i learned Taikyoku Shodan kata. it was learned as a pattern. it had no depth beyond the sequence of step, block, punch. it was only an exercise in memory, something to be memorized. then the next form and the next and the next. at some point i remember thinking that these forms have to have more to it. there is something i am missing here. as time progressed i began to dig into kata like an archaeologist. i find great depth of meaning in forms now. it is something that keeps me interested in the art, always learning more, finding something new.
i am not saying my way is correct and others are wrong,, i am only sharing my view.
The kata are not the system...the system is in the kata.
