It is to be understood that when Sri Caitanya Mahaprabhu chanted and danced, He did so by the influence of the pleasure potency of the spiritual world. Sri Caitanya Mahaprabhu never considered the holy name of the Lord to be a material vibration, nor does any pure devotee mistake the chanting of the Hare Krsna mantra to be a material musical manifestation. Lord Caitanya never tried to be the master of the holy name; rather He taught us how to be servants of the holy name. If one chants the holy name of the Lord just to make a show, not knowing the secret of success, he may increase his bile secretion, but he will never attain perfection in chanting the holy name.
