When it comes to understanding forms and the movements vs strict adherence form
here are a quotes from some of the masters:
Masutatsu Oyama – “unfortunately, many experienced karateka, having learnt many kata, mistakenly believe they have mastered them, when in truth they are merely dancing. To ensure kata are what they should be, you must completely understand the significance of the movements.”
Gichin Funakoshi – “Once a kata has been learned, it’s moves must be practiced repeatedly until it can be applied in an emergency. Knowledge of just the sequence of kata in karate is useless.”
Gichin Funakoshi – “To practice kata is not to memorize an order. Find the katas that work for you, understand them, digest them.”
Gichin Funakoshi – “Hitting, thrusting, and kicking are not the only methods in kata. Throwing techniques and pressure against joints, grabbing, & seizing are included … all these techniques should be studied referring to basic kata.”
Gichin Funakoshi – “A student well versed in even one technique will naturally see corresponding points in other techniques. A upper level punch, a lower punch, a front punch and a reverse punch are all essentially the same.”
Gichin Funakoshi – “…about three years were required to learn a single kata, and usually even an expert of considerable skill would only know three, or at most five, kata.”
Gichin Funakoshi – “The «way», who will pass it on straight and well? …The karate students practice today is not the same karate that was practiced even as recently as ten years ago [this book was written in 1956], and it is a long way indeed from the karate I learned in Okinawa.”
Hironori Otsuka – “It is obvious that kata must be trained and practiced sufficiently, but one must not be ‘stuck’ in them. One must take from the kata to produce actions with no limits or else it becomes useless.”
Gogen Yamaguchi – “It is not the number of kata you know, but the Substance of the kata you have acquired.
