pitamaho me bhavadiya-sammatah

samprapitas tvam paramah sva-pitra
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
My grandfather Prahlada Maharaja is famous, being recognized by all Your devotees. Although harassed in many ways by his father, Hiranyakasipu, he still remained faithful, taking shelter at Your lotus feet.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
A pure devotee like Prahlada Maharaja, although harassed circumstantially in many ways, never gives up the shelter of the Supreme Personality of Godhead to take shelter of anyone else. A pure devotee never complains against the mercy of the Supreme Personality of Godhead. A vivid example is Prahlada Maharaja. Examining the life of Prahlada Maharaja, we can see how severely he was harassed by his own father, Hiranyakasipu, yet he did not divert his attention from the Lord even to the smallest extent. Bali Maharaja, following in the footsteps of his grandfather Prahlada Maharaja, remained fixed in his devotion to the Lord, despite the Lord’s having punished him.
