I remember this zen story… a monk that belonged to another sect came to this zen master and bragged about all the magic his own master could do. he could levitate (of course), and paint through the air, walk on water… lots of stuff. When he finally finished the zen master looked up at him and smiled, saying “Well, it’s possible that your cunning master can do all this but my magic is that when I’m hungry I eat, when I’m thirsty I drink and when I’m tired I sleep. Can your master do that?”.
I once thought one of my yoga teachers levitated. They had this early morning class on fridays that eventually I was the only one to attend. So it was just me and the two teachers, and we just did what whatever asanas we felt like before chanting together. At one point I turn around and it looked like one of my teachers was in fact levitation, sitting real still about a foot from the ground doing nadi shodan pranayama (sp?).
Turns out he was exactly one foot off the ground since he was balancing on one foot sitting in half lotus (what’s that asana called again?) and it was just the angle that made it look like he was levitating for a short moment. I remember however that my second though (after my initial surprise to see him levitate) was that “Nah, he can’t be, he’d never do that in public”. And I think that’s true, even if he’d actually known how to levitate, if that’s even possible, he’d never show anyone.
Anyway, the videos posted here showed nothing but people trying to jump sitting in lotus position, which isn’t very impressive. They weren’t even jumping that high.
