Abstract

Frontal, central and parietal power and coherence of ten subjects practicing the TM-Sidhi technique of Yogic Flying (YF) were compared to that often controls who jumped from a seated position to approximate hopping during YF. All movement artifacts were removed before signal analyses. The most significant group differences were seen in the 2.12-second period just before lift-off: the YF subjects 30–32Hz power, and theta, alpha, and beta (broad band) coherence were significantly higher than those of the controls'. Within the YF group, the first period's 30–32 Hz power and broad-band coherence were significantly higher than those of the two preceding 2.12-s periods, and of the whole YF period. There were no significant within-group differences in the control group. A similar EEG pattern has been reported during the experience of pure consciousness in TM practice, suggesting that the experience of “pure consciousness” underlies successful TM-Sidhi performance.
