Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Narada Muni continued: O King, although the exalted devotee Prahlada Maharaja was only a little boy, he accepted Lord Brahma’s words. He gradually proceeded toward Lord Nrsimhadeva and fell down to offer his respectful obeisances with folded hands.
