When a devotee on whose lips the holy name is vibrated appears in this world—a devotee who has a taste for the holy name, who sees Krishna present in His holy name, and who loves Krishna—imports the holy name for the benefit of others. When such a devotee chants, he gives everyone an opportunity to come in contact with Krishna.
