Mahanidhi Swami, in his book ‘The Art of Chanting Hare Krishna,’ enumerates some of the benefits of chanting the maha-mantra (p13): “Chanting Krsna’s sweet names purifies the heart; sanctifies and steadies the mind; destroys the six enemies [lust, anger, greed, envy, illusion, madness]; stops birth and death; dissolves sins; scorches samskaras; annihilates attachment; induces detachment; uproots desires, empowers one, makes one fearless; removes illusion; bestows supreme peace; delivers prema; reveals the Lord and His dhama; shows one’s svarupa; showers bhaki-rasa; and engages one in His nitya-seva for the pleasure of Radha syhama.”
