CC Antya-lila

Thus worship the Lord, whose name is like the sun, for just as a slight appearance of the sun dissipates the darkness of night, so a slight appearance of the holy name of Kṛṣṇa can drive away all the darkness of ignorance that arises in the heart due to greatly sinful activities performed in previous lives.

CC Antya 3.62, Translation and Purport:

"O reservoir of all good qualities, just worship Śrī Kṛṣṇa, the purifier of all purifiers, the most exalted of the personalities worshiped by choice poetry. Worship Him with a faithful, unflinching mind, without duplicity and in a highly elevated manner. Thus worship the Lord, whose name is like the sun, for just as a slight appearance of the sun dissipates the darkness of night, so a slight appearance of the holy name of Kṛṣṇa can drive away all the darkness of ignorance that arises in the heart due to greatly sinful activities performed in previous lives."
