A Bengali mystic, guru, "poet", "composer", and publicity hound, based in the US for ~40 years. His first bout of fame came via the rock industry - e.g., he was the man who renamed John McLaughlin "Mahavishnu"; McLaughlin, in turn, introduced him to Carlos Santana. In recent decades, he and his devotees have been active in "public service" projects and world-record stunts, usually involving feats of physical endurance and strength.
