“ ‘Let there be all victory for the chanting of the holy name of Lord Kṛṣṇa, which can cleanse the mirror of the heart and stop the miseries of the blazing fire of material existence. That chanting is the waxing moon that spreads the white lotus of good fortune for all living entities. It is the life and soul of all education. The chanting of the holy name of Kṛṣṇa expands the blissful ocean of transcendental life. It gives a cooling effect to everyone and enables one to taste full nectar at every step.’
