Srimad-Bhagavatam

SB Canto 6

The purport is that one should take shelter of Kṛṣṇa-Balarāma, the Supreme Personality of Godhead, whose protective power is so great that it cannot be equaled in the material world. However powerful the reactions of one's sins, they will immediately be vanquished if one chants the name of Hari, Kṛṣṇa, Balarāma or Nārāyaṇa.

SB 6.2.16, Translation and Purport

Authorities who are learned scholars and sages have carefully ascertained that one should atone for the heaviest sins by undergoing a heavy process of atonement and one should atone for lighter sins by undergoing lighter atonement. Chanting the Hare Kṛṣṇa mantra, however, vanquishes all the effects of sinful activities, regardless of whether heavy or light.

As stated in Śrīmad-Bhāgavatam (SB 11.2.42), bhaktiḥ pareśānubhavo viraktir anyatra ca: devotional service is so powerful that one who performs devotional service is immediately freed from all sinful desires. All desires within this material world are sinful because material desire means sense gratification, which always involves action that is more or less sinful. Pure bhakti, however, is anyābhilāṣitā-śūnya; in other words, it is free from material desires, which result from karma and jñāna. One who is situated in devotional service no longer has material desires, and therefore he is beyond sinful life. Material desires should be completely stopped. Otherwise, although one's austerities, penances and charity may free one from sin for the time being, one's desires will reappear because his heart is impure. Thus he will act sinfully and suffer.
