(Prahlad Maharaj pacifies Lord Nrsimhadeva)
"Nṛsiṁha-deva offered Prahlāda Mahārāja, 'Now you can take any kind of benediction you like.' So Prahlāda Mahārāja replied, 'My Lord, we are materialists. I am born of a father absolutely materialist. So I am also, because I am born of a materialist father, I am also materialist. And You, the Supreme Personality of Godhead, You are offering to give me some benediction. I can take any kind of benediction from You. I know that. But what is the use of it? Why shall I ask You for any benediction? I have seen my father.
Materially, he was so powerful that even the demigods, Indra, Candra, Varuṇa, they were threatened by his red eyes. And he gained over control over the universe. He was so powerful. And riches, wealth, power, reputation, everything complete. But You have finished it in one second. So why You are offering me such benediction? What shall I do with them? If I take that benediction from You and I become puffed up and do everything wrong against You, then You can finish it within a second. So kindly do not offer me such benediction, such material opulence. Better give me benediction to be engaged in the service of Your servant. I want this benediction. Let me be benedicted by You that I may be engaged in the service of Your servant, not directly Your servant.'
Then, after many prayers, after pacifying the Lord... He was very angry. Then when He (Nṛsiṁha-deva) was little pacified, he (Prahlāda) asked, 'My dear Lord, I can ask You one, another benediction: that my father was very, very staunch enemy of You. That was the cause of his death. Now I ask You, kindly excuse him and give him liberation.' This is Vaiṣṇava son. He did not ask anything for himself. And although he knew that his father was the greatest enemy, still, he is asking his benediction, 'This poor fellow may be liberated.' So Lord Nṛsiṁha-deva guaranteed, said, 'My dear Prahlāda, not only your father, but your father's father, his father, up to fourteen generations, all are liberated because you are born in this family.'
So anyone who has become a Vaiṣṇava, a devotee of the Lord, he is giving the greatest service to the family. Because in relationship with him, his father, mother, anyone, they will be liberated. Just like we have got experience: if a person dies in the fight immaturely, his family is taken care of by the government. Similarly, to become a devotee is the greatest qualification. He has got everything. Yatra yogeśvaro hariḥ yatra dhanur-dharaḥ pārthaḥ. When there is Kṛṣṇa and when there is devotee, all victory, all glories are there. That is guaranteed."
