Sound vibration is all powerful. Any seasoned mountain climber knows that mantras can cause avalanches, and we have heard how certain sopranos can break drinking glasses. We learn from Vedic sources that sound does, literally, move mountains. Snake charmers and Vedic ‘medicine men’ have worked ‘miracles’ with mantras. One can just imagine then how powerful the Hare Krishna mantra is, given that it is what Prabhupada once called, the ‘great chant for deliverance.’
