SB 4.31.25
etat te ’bhihitam ksattar
yan mam tvam pariprstavan
pracetasam naradasya
samvadam hari-kirtanam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
My dear Vidura, I have told you everything you wanted to know about the conversation between Narada and the Pracetas, the conversation describing the glories of the Lord. I have related this as far as possible.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Srimad-Bhagavatam describes the glories of the Lord and His devotees. Because the whole subject matter is the glorification of the Lord, naturally the glorification of His devotees automatically follows.
