Through the principles of religion, one can understand the Supreme Personality of Godhead, Brahman (the impersonal feature of the Supreme Lord) and Paramātmā (the localized aspect of the Lord). When one is well conversant with all these principles, he becomes a devotee and performs bhāgavata-dharma. Prahlāda Mahārāja, the spiritual master in the line of disciplic succession, advised that this bhāgavata-dharma be instructed to students from the very beginning of their education ( kaumāra ācaret prājṣo dharmān bhāgavatān iha ). To understand the science of the Supreme Personality of Godhead is the real purpose of education. Śravaṇaṁ kīrtanaṁ viṣṇoḥ. One must simply hear about and describe Lord Viṣṇu and His various incarnations. This narration concerning Prahlāda Mahārāja and Lord Nṛsiṁhadeva, therefore, has properly described spiritual, transcendental subjects.
