Srimad-Bhagavatam: Canto 12 - Chapter 1 - Verse 314
राजन्ते तावदन्यानि पुराणानि सतां गणे ।यावद्भागवतं नैव श्रूयतेऽमृतसागरम् ॥ १४ ॥
rājante tāvad anyānipurāṇāni satāṁ gaṇeyāvad bhāgavataṁ naivaśrūyate ’mṛta-sāgaram
All other Purāṇic scriptures shine forth in the assembly of saintly devotees only as long as that great ocean of nectar, Śrīmad-Bhāgavatam, is not heard.
Other Vedic literatures and other scriptures of the world remain prominent until the Śrīmad-Bhāgavatam is duly heard and understood. Śrīmad-Bhāgavatam is the ocean of nectar and the supreme literature. By faithful hearing, recitation and distribution of Śrīmad-Bhāgavatam, the world will be sanctified and other, inferior literatures will fade to minor status.
