Srila Jiva Gosvami cites a verse from the Vedic literature which says that there is no necessity of performing sacrificial demonstrations or ceremonial functions. He comments that instead of engaging in such external, pompous exhibitions, all people, regardless of caste, color or creed, can assemble together and chant Hare Krsna to worship Lord Caitanya. Krsna-varnam tvisakrsnam [SB 11.5.32] indicates that prominence should be given to the name of Krsna.
