Bhagavatapurana 6.3.32

32. The mind does not become so purified by fasting and other vows as it does by means of the well-developed devotion of these who constantly listen to and sing the glorious and extraordinary powers of Hari.

33. He, who tastes the sweet juice in the lotuses of Sri Krishna's feet, does not again find delight in the objects created by Maya, leading to sin. The other man whose heart is profaned with desires would only do Karma to wipe off sin (dirt) in his heart; but that Karma would only lead to the growth of sin again.
