Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Because of the favor of the brahmanas, the great soul Bali Maharaja, thinking himself very satisfied, became very opulent and prosperous and began to enjoy the kingdom.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The brahmanas are called dvija-deva, and ksatriyas are generally called nara-deva. The word deva actually refers to the Supreme Personality of Godhead. The brahmanas guide human society in becoming happy by satisfying Lord Visnu, and according to their advice, the ksatriyas, who are called nara-deva, keep law and order so that other people, namely the vaisyas and sudras, may properly follow regulative principles. In this way, people are gradually elevated to Krsna consciousness.
Thus end the Bhaktivedanta purports of the Eighth Canto, Fifteenth Chapter, of the Srimad-Bhagavatam, entitled “Bali Maharaja Conquers the Heavenly Planets.”
