Srila Prabhupada emphasizes in his purport to Narrotama dasa Thakura’s Svarana-Gaura-mahima (Gaurangera duti pada) that purification is achieved through chanting, dancing and taking prasadam. “Lord Caitanya’s pastimes are very pleasing, because the basic principles of Lord Caitanya Mahaprabhu’s movement are chanting, dancing and eating Krsna-prasada.” In the same paragraph he says, “The heart of anyone who takes to this movement of chanting, dancing ah, and eating Krsna-prasada will surely be cleansed of all dirty material contamination.”
