Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Although Prahlada Maharaja was born in a family of asuras, he himself was not an asura but a great devotee of Lord Visnu. Unlike the other asuras, he was never envious of Vaisnavas. He was not agitated when put into danger, and he was neither directly nor indirectly interested in the fruitive activities described in the Vedas. Indeed, he considered everything material to be useless, and therefore he was completely devoid of material desires. He always controlled his senses and life air, and being of steady intelligence and determination, he subdued all lusty desires.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
From this verse we discover that a man is not qualified or disqualified simply by birth. Prahlada Maharaja was an asura by birth, yet he possessed all the qualities of a perfect brahmana (brahmanyah sila-sampannah). Anyone can become a fully qualified brahmana under the direction of a spiritual master. Prahlada Maharaja provided a vivid example of how to think of the spiritual master and accept his directions calmly.
