Śrīmad-Bhāgavatam · Text 11.2.55
Who is speaking and story frame
विसृजति हृदयं न यस्य साक्षा-
द्धरिरवशाभिहितोऽप्यघौघनाश: ।
प्रणयरसनया धृताङ्घ्रिपद्म:
स भवति भागवतप्रधान उक्त: ॥ ५५ ॥
visṛjati hṛdayaṁ na yasya sākṣād
dharir avaśābhihito ’py aghaugha-nāśaḥ
praṇaya-rasanayā dhṛtāṅghri-padmaḥ
sa bhavati bhāgavata-pradhāna uktaḥ
The Supreme Personality of Godhead is so kind to the conditioned souls that if they call upon Him by speaking His holy name, even unintentionally or unwillingly, the Lord is inclined to destroy innumerable sinful reactions in their hearts. Therefore, when a devotee who has taken shelter of the Lord’s lotus feet chants the holy name of Kṛṣṇa with genuine love, the Supreme Personality of Godhead can never give up the heart of such a devotee. One who has thus captured the Supreme Lord within his heart is to be known as bhāgavata-pradhāna, the most exalted devotee of the Lord.
