Suresvara das: So during the guru-puja, I remember some brahmacharis, they had developed a kind of boogying, doing rock dancing. This was going on during guru-puja and all of a sudden Prabhupada, like a conductor, like a maestro, he stopped the guru-puja cold in an instant and we were all frozen in place. Then Prabhupada gestures to the picture of the Pancha-tattva in the distance and how their arms are upraised and he says, "Dance, dance like Sri Chaitanya Mahaprabhu." So we were all corrected because we were all getting into disco dancing, twisting and boogaloo and shingaling and whatever.
