I'll pose a re-starting point. There are a few things about a kata in general that are interesting to note, but don't add one minute of experience to the actual practice of it. kata are physically learned from an instructor, and practiced for years. no other way. even if someone found the rosetta stone with a lost kata scribed on it, it would be just movements just a choreography without meaning. Thats enough for many. They 'want' the kata - but what they really want is just the hollow shape of it. This 'want' is satisfied by providing it to them...for a price of course. video or seminar take your pick.
This is why all the people who come on here and say they have a rare, esoteric, protected or lost kata aren't willing to provide an mpeg for it. ...since THAT is their product! why give it away from free?
some will say they will teach it for free, but you need to come to them. do you really think it's free? years ago, I got a call from a place in Cape Cod telling me that if I go to their 'open house' of condo sales, then I get a free stereo. NO obligation and it's free...just show up, listen, then claim your gift. cool! I thought. The pressure they put on people to commit to something before leaving with their free piece of junk plastic stereo was incredible. My drill seargant could have taken lessons from these marketing nazis of how to mind-screw and psych-battle fatigue people. needless to say, I didn't sign on the dotted line and got a slave-labor made stereo tossed to me. It really wasn't worth wasting the day.
before wasting a plane ticket or going out of your way in time or money, if anyone claims to know and teach something to you, make sure you:
A. know and trust someone who recommends checking it out or has trained at least once with the SAME person you are going to see.
B. Realize that 'secrets' can't be given in one sitting or viewing. They are physically realized over a period of time of practice and correction.
C. Insist on seeing a clip or video of at least a taste of what you'll be shown.
D. don't be pressured into anything you aren't comfortable with. 'peer pressure' and 'guilt trip' tactics come to mind.
realize before all of this, that anyone claiming to teach for free loudly, obviously doesn't have enough students for a reason. The reason could be anything from, they don't have anything worth staying for, to they are 'spreading their word' for free in the hopes to attract attention that they can charge many others for later. organizational recruitment comes to mind. "join are org! it's free!" uh-huh.

Good instructors are simply not loudmouths or braggarts.
back to the Channan topic...have a good thread.

p.s. I have a theory: Channan is not the name of a kata at all...it's a girl's name who knows 'ALL your secrets'.
