Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Please also describe the incarnations of the material modes of nature — Brahma, Visnu and Mahesvara — and please describe the incarnation of the Supreme Personality of Godhead and His magnanimous activities.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Although Brahma, Visnu and Mahesvara, the three incarnations of the material modes of nature, are the principal deities for the creation, maintenance and destruction of the cosmic manifestation, they are not the final authority. The Supreme Personality of Godhead, Lord Krsna, is the ultimate goal, the cause of all causes. He is the asraya, or the final rest of everything.
