The sound incarnation of Lord Kṛṣṇa, the Supreme Soul [i.e., Śrīmad-Bhāgavatam], enters into the heart of a self-realized devotee, sits on the lotus flower of his loving relationship, and thus cleanses the dust of material association, such as lust, anger and hankering. Thus it acts like autumnal rains upon pools of muddy water.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
प्रविष्टः कर्णरन्ध्रेण स्वानां भावसरोरुहम् । धुनोति शमलं कृष्णः सलिलस्य यथा शरत्
praviṣṭaḥ karṇarandhreṇa svānāṃ bhāvasaroruham | dhunoti śamalaṃ kṛṣṇaḥ salilasya yathā śarat
