brahmādayo vayam iveśa na codvijantaḥ
kṣemāya bhūtaya utātma-sukhāya cāsya
vikrīḍitaṁ bhagavato rucirāvatāraiḥ
Prahlāda Mahārāja wanted to assert that his father and the other members of his family were all unfortunate because they were demoniac, whereas the devotees of the Lord are always fortunate because they are always ready to follow the orders of the Lord. When the Supreme Lord appears in this material world in His various incarnations, He performs two functions — saving the devotee and vanquishing the demon (paritrāṇāya sādhūnāṁ vināśāya ca duṣkṛtām). Lord Nṛsiṁhadeva, for example, appeared for the protection of His devotee. Such pastimes as those of Nṛsiṁhadeva are certainly not meant to create a fearful situation for the devotees, but nonetheless the devotees, being very simple and faithful, were afraid of the fierce incarnation of the Lord. Therefore Prahlāda Mahārāja, in the following prayer, requests the Lord to give up His anger.
