Chanting of the holy names of the Lord is perfect in every way. When Dhruva Maharaja saw the Visnudutas, the direct associates of Lord Visnu, four-handed and nicely decorated, he could understand who they were, but for the time being he was puzzled. But simply by chanting the holy name of the Lord, the Hare Krsna mantra, he could satisfy the uncommon guests who had all of a sudden arrived before him. The chanting of the holy name of the Lord is perfect; even though one does not know how to please Lord Visnu or His associates, simply by sincerely chanting the holy name of the Lord, everything becomes perfect. A devotee, therefore, either in danger or in happiness, constantly chants the Hare Krsna mantra. When he is in danger he is immediately relieved, and when he is in a position to see Lord Visnu or His associates directly, by chanting this maha-mantra he can please the Lord. This is the absolute nature of the maha-mantra. Either in danger or in happiness, it can be chanted without limitation.
