Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The great saint Narada Muni continued: The demigods, headed by Lord Brahma, Lord Siva and other great demigods, dared not come forward before the Lord, who at that time was extremely angry.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Srila Narottama dasa Thakura has sung in his Prema-bhakti-candrika, ‘krodha’ bhakta-dvesi-jane: anger should be used to punish a demon who is envious of devotees. Kama, krodha, lobha, moha, mada and matsarya — lust, anger, greed, illusion, pride and envy — all have their proper use for the Supreme Personality of Godhead and His devotee. A devotee of the Lord cannot tolerate blasphemy of the Lord or His other devotees, and the Lord also cannot tolerate blasphemy of a devotee. Thus Lord Nrsimhadeva was so very angry that the great demigods like Lord Brahma and Lord Siva and even the goddess of fortune, who is the Lord’s constant companion, could not pacify Him, even after offering prayers of glorification and praise. No one was able to pacify the Lord in His anger, but because the Lord was willing to exhibit His affection for Prahlada Maharaja, all the demigods and the others present before the Lord pushed Prahlada Maharaja forward to pacify Him.
