srimad-bhagavatam puranam amalam yad vaisnavanam priyam
yasmin paramahamsyam ekam amalam jñanam param giyate
tatra jñana-viraga-bhakti-sahitam naiskarmyam aviskrtam
tac chrnvan su-pathan vicarana-paro bhaktya vimucyen narah
Translation:
Srimad-Bhagavatam is the spotless Purana. It is most dear to the Vaisnavas because it describes the pure and supreme knowledge of the paramahamsas. This Bhagavatam reveals the means for becoming free from all material work, together with the processes of transcendental knowledge, renunciation and devotion. Anyone who seriously tries to understand Srimad-Bhagavatam, who properly hears and chants it with devotion, becomes completely liberated.
Purport:
Because Srimad-Bhagavatam is completely free of contamination by the modes of nature, it is endowed with extraordinary spiritual beauty and is therefore dear to the pure devotees of the Lord. The word paramahamsyam indicates that even completely liberated souls are eager to hear and narrate Srimad-Bhagavatam. Those who are trying to be liberated should faithfully serve this literature by hearing and reciting it with faith and devotion.
