Humble sincerity in loving service conquers Krishna more than any material qualification or intellectual prowess.Listen — Srila Prabhupada Uvaca
Hṛdayānanda: "Thereafter Lord Brahmā requested Prahlāda Mahārāja, who was standing very nearby, and asked Prahlāda Mahārāja to go forward and said, 'My dear son, Lord Nṛsiṁhadeva is very, very angry upon your demonic father, and you can go forward and appease Him, the Lord.' " Prabhupāda: prahrādaṁ preṣayām āsa brahmāvasthitam antike tāta praśamayopehi sva-pitre kupitaṁ prabhum [SB 7.9.3] So all of them, all the demigods, they wanted to pacify. The Lord was very angry, but they failed. Then, at last, they requested Lakṣmījī to pacify the Lord. She could not dare to approach, what is the speaking of pacifying?
Then, at last, they decided that "This five-years-old boy, the Lord may be compassionate upon him. And for him He has appeared, so let him be engaged in pacifying the Lord." So Brahmā, the head of all the demigods presented there, he decided, prahlādaṁ preṣayām āsa. He pushed him forward: "My dear Prahlāda, my dear son, better you go forward and pacify." It is something like to push a little child in the cage of the lion. It is something like that.
Nobody dared. So Prahlāda Mahārāja, he knew very well that "However ferocious He may be, I am not afraid. He is my Lord. I am not afraid." He was jolly, innocent, pure devotee.
He had no fear. So he was sent: "My dear Prahlāda, you try." So brahmā avasthitam antike. He was very near sitting, but he had no fear. Just on the lotus feet, near the lotus feet of the Lord, he was sitting.
Others were contemplating. He was free, that "I am under the shelter of the Lord." Svapāda-mūle [SB 7.9.5], mahat-padaṁ puṇya-yaśo murāreḥ [SB 10.14.58]: "He is Murāri, and everything is under His feet." This is the conclusion when one is advanced in Kṛṣṇa consciousness. Prahlāda Mahārāja, although he was a boy of five years old, it did not matter. He was first-class devotee, maha-bhāgavata.
That is possible. The devotional service is nothing material; it is spiritual. So there is nothing impossible, impossible. That is real appreciation of spiritual life.
If one thinks that "Prahlāda Mahārāja was only five years old. How he could offer such nice verses in glorifying the Lord?" that is possible. Bhakti does not depend on the age. Bhakti depends on sincerity of service.
