A perfect devotee of Lord Kṛṣṇa (Viṣṇu). His father, Hiraṇyakaśipu, chastised him severely when he was only five years old for his becoming an unalloyed devotee of the Lord. He was the first son of Hiraṇyakaśipu, and his mother’s name was Kayādhu. Prahlāda Mahārāja was an authority in the devotional service of the Lord because he had his father killed by Lord Nṛsiṁhadeva, setting the example that even a father should be removed from the path of devotional service if such a father happens to be an obstacle. He had four sons, and the eldest son, Virocana, is the father of Bali Mahārāja, mentioned above. The history of Prahlāda Mahārāja’s activities is described in the Seventh Canto of Śrīmad-Bhāgavatam.
