SB 7.5.6
sri-narada uvaca
srutva putra-giro daityah
para-paksa-samahitah
jahasa buddhir balanam
bhidyate para-buddhibhih
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Narada Muni continued: When Prahlada Maharaja spoke about the path of self-realization in devotional service, thus being faithful to the camp of his father’s enemies, Hiranyakasipu, the King of the demons, heard Prahlada’s words and he laughingly said, “Thus is the intelligence of children spoiled by the words of the enemy.”
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Hiranyakasipu, being a demon, would always consider Lord Visnu and His devotees to be his enemies. Therefore the word para-paksa (“on the side of the enemy”) is used here. Hiranyakasipu never agreed with the words of Visnu, or Krsna. Rather, he was angered by the intelligence of a Vaisnava. Lord Visnu, Lord Krsna, says, sarva-dharman parityajya mam ekam saranam vraja — “Give up all other duties and surrender unto Me” — but demons like Hiranyakasipu never agree to do this. Therefore Krsna says:
na mam duskrtino mudhah
prapadyante naradhamah
mayayapahrta-jñana
asuram bhavam asritah
“Those miscreants who are grossly foolish, lowest among mankind, whose knowledge is stolen by illusion, and who partake of the atheistic nature of demons, do not surrender unto Me.” (Bg. 7.15) The asura-bhava, the atheistic nature, is directly represented by Hiranyakasipu. Such persons, being mudha and naradhama — fools and rascals, the lowest of men — would never accept Visnu as the Supreme and surrender to Him. Hiranyakasipu naturally became increasingly angry that his son Prahlada was being influenced by the camp of the enemies. He therefore asked that saintly persons like Narada not be allowed within the residential quarters of his son, for otherwise Prahlada would be further spoiled by Vaisnava instructions.
