This is a prime example of confusion between a martial art and sport or a martial artist and one who plays games. Kata are the center of martial training they build spirit, timing, control, strength, and focus. Yes, sports are similar, however no sport places the ability of life and death of one person in the psychy of another. Training kata allows the individual to eliminate the self so that the world can be seen as it truly is; "Meet the Buddah, Kill the Buddah". The martial arts are just that, martial, ie. life and death. Its training is forever as are the kata. Every time a kata is practised the self becomes less and the kata becomes more. The spirit of the kata embodies all those who have trained before you. Maybe you should research the term mushin. Thank you.
