@UltraRishi Thanks for your post. Congratulations on your navigation through kriyas and kundalini!
Kriyas are what TM teachers used to call “movements in meditation”. Surprisingly, TMers, other Eastern spiritual movements, and even Christian Charismatics have kriyas. There is a hilarious YouTube video put to a Jerry Lee Lewis tune that shows the gyrations/kriyas of Charismatic Christians. The video is entitled “Whole Lotta Shakin' Goin' On! Holy Roller Style!” and is at https://www.youtube.com/watch?v=QWVHpm49tOU. >From my book describing kriyas during instruction in the TM-Sidhi on >levitation: “Some participants had rather violent head movements, the torsos >of some shook like dogs throwing off water from a bath, others had their backs >locked in an arch, and others had spontaneous vocalizations of screams, barks, >and nonsense syllables.”
