Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Narada Muni continued: When the saintly person was thus questioned by Prahlada Maharaja, the King of the Daityas, he was captivated by this shower of nectarean words, and he replied to the inquisitiveness of Prahlada Maharaja with a smiling face.
