An intelligent person who has controlled his mind and conquered fear should give up all attachment to material objects such as wife, family and nation and should wander freely without embarrassment, hearing and chanting the holy names of the Lord, the bearer of the chariot wheel. The holy names of Kṛṣṇa are all-auspicious because they describe His transcendental birth and activities, which He performs within this world for the salvation of the conditioned souls. Thus the holy names of the Lord are sung throughout the world.
