Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The principles of religion by which one can actually understand the Supreme Personality of Godhead are called bhagavata-dharma. In this narration, therefore, which deals with these principles, actual transcendence is properly described.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Through the principles of religion, one can understand the Supreme Personality of Godhead, Brahman (the impersonal feature of the Supreme Lord) and Paramatma (the localized aspect of the Lord). When one is well conversant with all these principles, he becomes a devotee and performs bhagavata-dharma. Prahlada Maharaja, the spiritual master in the line of disciplic succession, advised that this bhagavata-dharma be instructed to students from the very beginning of their education (kaumara acaret prajño dharman bhagavatan iha). To understand the science of the Supreme Personality of Godhead is the real purpose of education. Sravanam kirtanam visnoh. One must simply hear about and describe Lord Visnu and His various incarnations. This narration concerning Prahlada Maharaja and Lord Nrsimhadeva, therefore, has properly described spiritual, transcendental subjects.
