Oh, I'm not saying it's mystical.
It's science. Just have to learn the structure and the way energy flows.
meridians, acupuncture, acupressure, are these things mystical? Some people think so, but the Chinese treat it as science.
And Mook, I just put those videos up to show that watching videos of Chi demos can't prove anything to ya. You said it right, you've got to feel it done on you. As for guys getting hit with Chi several feet away, ah,.. I don't know about all that. But, that one guy blew out candles from far away. Or did he? Don't know. Was it enough force if he did to knock someone down? probably not, who knows?
And there is alot of physcological mind games teachers play with their students that are "fake" like some of these guys in online videos. But, if the power of the mind is strong enough to make the equipment of a paramedic's go nutz and the student actually feels this stuff because of his mind being tricked isn't that kinda the same thing? or similar? And then so, isn't the mind strong enough to develop chi in more amazing ways? And we're only limited to our minds limitations of accepance of what it THINKS it can do?
Deep. anyways!! lol!
Astrobiologist: Effectiveness of WC/WT:
I've got an idea for you as a new student. Take WC/WT classes for 3-6 months, depending on how often a week you train. If you train 2 days a week wait 6 months, if you train 2 or more days a week then wait 3 months. Then,,... go to the MMA gym and put on the gear and spar them. Use the WC/WT you've learned, test it, feel it out. Find out your strengths and weaknesses, find out WC/WT's strengths and weaknesses.
Then..., go back to Sifu and ask, "Sifu, I was sparring and the guy did "this" to me. I couldn't counter. What do I do if I'm attacked like that?" etc...
Then see what Sifu says. If he can answer to your satisfaction, or wants you to train longer or a bit harder in WC/WT groovy. If he doesn't want to fool with answering you or helping you. Bugger out of his Kwoon. Find another teacher. It's a self defense and combative art, he should be excited that you're wanting to apply it and spar right away.
Now, if he tells you to wait another couple of months before you spar at the MMA gym again. Then wait, and let him train you some more. Then go back every couple of months to see how your progressing. When you begin to feel more comfortable using the WC/WT in sparring with these guys, go more often. It'll be fun, and give you a goal to reach for when your training Wing Chun.
Make sense?
Train WC, take your time, learn it right, learn it pure and true, then spar when you feel ready. You'll know more than anyone else when YOUR ready to spar like that. Listen to your WC teacher and his/her suggestions on training, sparring, and counters. Even if it's weird. Trust your WC teacher. Ask questions.
