Srimad-Bhagavatam: Canto 7 - Chapter 1 - Verse 24


श्रीनारद उवाचप्रह्रादोऽपि तथा चक्रे पितुर्यत्साम्परायिकम् ।यथाह भगवान् राजन्नभिषिक्तो द्विजातिभि: ॥ २४ ॥


śrī-nārada uvācaprahrādo ’pi tathā cakrepitur yat sāmparāyikamyathāha bhagavān rājannabhiṣikto dvijātibhiḥ


Śrī Nārada Muni continued: Thus, as the Supreme Personality of Godhead ordered, Prahlāda Mahārāja performed the ritualistic ceremonies for his father. O King Yudhiṣṭhira, he was then enthroned in the kingdom of Hiraṇyakaśipu, as directed by the brāhmaṇas.


It is essential that society be divided into four groups of men — brāhmaṇas, kṣatriyas, vaiśyas and śūdras. Here we see that although Prahlāda was perfect in every respect, he nonetheless followed the instructions of the brāhmaṇas who performed the Vedic rituals. Therefore in society there must be a very intelligent class of leaders who are well versed in the Vedic knowledge so that they can guide the entire populace to follow the Vedic principles and thus gradually become most perfect and eligible to return home, back to Godhead.
