In a pristine office with huge windows overlooking midtown Manhattan, just steps away from the hustle and bustle of Penn Station, the transcendental meditation teacher Bob Roth sits not in flowing garb, but the blazer/pants combination that wouldn’t put him out of place on the streets of New York. Roth often invokes his choice of attire as the reason why he is able to convince skeptics that meditation isn’t “make believe woohoo.”
