As can be seen in the video there are invisible strikes. I would like to know where can I find more like those. In addition, I would like to know what is the idea and the tricks that stand beyond the invisible strikes?
The stuff shown in the video is nonsense that only works because of auto-suggestion or a kind of hypnosis. These students are not just moving in an accommodating, compliant way. They have been "programmed" (hypnotized essentially) to feel as if a powerful, invisible force is being used against themselves. It won't work on people who aren't that guy's students.
There are lots of examples of this happening in martial arts. Some would even go so far as to say it's cult-like. I get sick of seeing it. And my heart goes out to anyone who has been suckered into believing in this stuff. None of it is real. It's all in your head. And it's completely unreliable for martial arts. I just wish the martial arts community would spread the word and make sure to smack this down wherever and whenever it comes up again.
Hope that helps.
