Bunkai is a form of drill. You get it from kata. Pick a bit out of it and use it as training. It doesn't look any more complicated or mysterious than any other drill compliant or resisted drill that pretty much every else.
Okay, now we have something to work with.
Nope. Rather incorrect, to be frank. Bunkai is actually not a "form of drill"ā¦ it is quite literally an "exploration"ā¦ an attempt to look into the possibilities inherent in the actions of the kata itself. In other words, there isn't any set drill that is bunkaiā¦ bunkai is created individually, and often looks like what you think are drills, but that's really simply the way the bunkai is explored.
The actual movements themselves aren't any more mysterious, complicated, or anything elseā¦ in fact, you wouldn't want them to beā¦ but what they are is an expression of the tactical applications found within the kata themselves. They (ideally) are designed with the realities of inter-relationships (natural reactions, what you would likely consider "resistance", although again, that's actually not realistic), distancing, timing, and so forth, although that's not essential either. All that's really needed for bunkai is that is is an exploration of the possibilities within the kata.
As far as breaking people. How old are you? Seriously in some styles you are actually allowed to fight back even if it seems like they are being a jerk.
You really want to try this? Mate, if you're a jerk in training, you will deserve a harsh response. And "fighting back" is not being a jerkā¦ again, the idea that you can't see the difference doesn't bode well for your understandingā¦ or your ability to engage with people.
That is what sparring is and why it is important.
No, it isn't. Sparring is a training device with the aim of skill development, not where one person actively tries to stop the other developing.
