Translation: 
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.
Purport: 

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.
