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 matsaryalust, anger, greed, illusion, pride and envyall 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 Lords 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.
