Translation: 
Śrī Nārada Muni said: My dear King Yudhiṣṭhira, when Lord Viṣṇu, in the form of Varāha, the boar, killed Hiraṇyākṣa, Hiraṇyākṣa’s brother Hiraṇyakaśipu was extremely angry and began to lament.
Purport: 

Yudhiṣṭhira had inquired from Nārada Muni why Hiraṇyakaśipu was so envious of his own son Prahlāda. Nārada Muni began narrating the story by explaining how Hiraṇyakaśipu had become a staunch enemy of Lord Viṣṇu.
