Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sri Sukadeva Gosvami said: Thus the chief of the sages, who was always enthusiastic about describing topics regarding the Personality of Godhead, began to narrate the descriptive explanation of the Puranas, being so infused by Vidura. He was very much enlivened by speaking on the transcendental activities of the Lord.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Great learned sages like Maitreya Muni are always very enthusiastic about describing the transcendental activities of the Lord. Maitreya Muni, being thus invited by Vidura to speak, appeared to be smiling because he actually felt transcendental bliss.
Thus end the Bhaktivedanta purports of the Third Canto, Seventh Chapter, of the Srimad-Bhagavatam, entitled “Further Inquiries by Vidura.”
