Srimad Bhagavatam Canto 12, Chapter 13, Text 14

SB 12.13.14

rajante tavad anyani
 puranani satam gane
yavad bhagavatam naiva
 sruyate ’mrta-sagaram
 
Translation: 
 
All other Puranic scriptures shine forth in the assembly of saintly devotees only as long as that great ocean of nectar, Srimad-Bhagavatam, is not heard.
 
Purport: 
 
Other Vedic literatures and other scriptures of the world remain prominent until the Srimad-Bhagavatam is duly heard and understood. Srimad-Bhagavatam is the ocean of nectar and the supreme literature. By faithful hearing, recitation and distribution of Srimad-Bhagavatam, the world will be sanctified and other, inferior literatures will fade to minor status.
