I'm one of those who doesn't understand it and thinks it's fake. Please try to disabuse me of my opinion. Have you experienced what he's doing yourself? Can you do it? Can any of his students do it? Tell us about your experiences or of your knowledge of Hasim Sensei's skill as demonstrated on this video clip.
Looks like he's one of Takeda Yoshinobu's students:
I talked to another Yamaguchi Seigo student (of about the same vintage as Takeda) about this kind of thing last year - he started with "hypnotism" and "brain washing", and it went downhill from there :-).
