Srimad-Bhagavatam: Canto 12 - Chapter 1 - Verse 15
Sanskrit:
यस्तूत्तम:श्लोकगुणानुवाद:सङ्गीयतेऽभीक्ष्णममङ्गलघ्न: ।तमेव नित्यं शृणुयादभीक्ष्णंकृष्णेऽमलां भक्तिमभीप्समान: ॥ १५ ॥
ITRANS:
yas tūttamaḥ-śloka-guṇānuvādaḥsaṅgīyate ’bhīkṣṇam amaṅgala-ghnaḥtam eva nityaṁ śṛṇuyād abhīkṣṇaṁkṛṣṇe ’malāṁ bhaktim abhīpsamānaḥ
Translation:
The person who desires pure devotional service to Lord Kṛṣṇa should hear the narrations of Lord Uttamaḥśloka’s glorious qualities, the constant chanting of which destroys everything inauspicious. The devotee should engage in such listening in regular daily assemblies and should also continue his hearing throughout the day.
Purport:
Since any topic related to Lord Kṛṣṇa is auspicious and transcendental, the direct narration of Lord Kṛṣṇa’s own activities, political and nonpolitical, is certainly the supreme subject matter for hearing. The word nityam here indicates regulated cultivation of the topics of Lord Kṛṣṇa, and abhīkṣṇam indicates constant remembrance of such regulated spiritual experiences.
