My question to you is .... ?
What kind of martial artist are you?
History tells us, that as far as Shotokan Karate is concerned, starting and ending a kata on exactly the same spot, only came into existance in the modern era. It came about a simply one more way of determing the winner when tournament karate came into being.
So here is my question to you.
Are you a modern martial artist?
By that I mean do you make every effort to start, and finish every kata on the same spot? Do you carry that thought with you as you do your kata and adjust your stances accordingly? Do you look for that spot it as you near the finish, and make it one of your goals?
Are you a classical martial artist?
By that I mean do you start and finsh on the same spot, but only if correct stances got you there? Making the kata alone your prime focus and never the finish?
In reality, being a modern martial artist, or a classical martial artist, will only matter to you, your sensei, and your fellow students.
What I find it interesting, is how many students never realized that there were two options.
Remember: "What others do is also right, even if it is not your way?"
