Looking to learn more about the guru behind TM, I found this documentary. Excellent for learning something of how he became so famous. Thankfully, he was also a real yogi.
Yogic "flight" (bouncing up and down on a cushion in lotus) as shown in the video looks kind of silly from the outside; however, when I gave it a try this morning, it was a bit of a thrill from the inside. The body flies up in a semi-spontaneous flow, and as it is coming back down, thanks to gravity, for a moment one can imagine continuing upward as if in a flight beyond gravity.
