Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Sri Narada Muni said: My dear King Yudhisthira, when Lord Visnu, in the form of Varaha, the boar, killed Hiranyaksa, Hiranyaksa’s brother Hiranyakasipu was extremely angry and began to lament.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Yudhisthira had inquired from Narada Muni why Hiranyakasipu was so envious of his own son Prahlada. Narada Muni began narrating the story by explaining how Hiranyakasipu had become a staunch enemy of Lord Visnu.
