kasmin yuge pravrtteyam
sthane va kena hetuna
kutah sañcoditah krsnah
krtavan samhitam munih
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
In what period and at what place was this first begun, and why was this taken up? From where did Krsna-dvaipayana Vyasa, the great sage, get the inspiration to compile this literature?
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Because Srimad-Bhagavatam is the special contribution of Srila Vyasadeva, there are so many inquiries by the learned Saunaka Muni. It was known to them that Srila Vyasadeva had already explained the text of the Vedas in various ways up to the Mahabharata for the understanding of less intelligent women, sudras and fallen members of the family of twice-born men. Srimad-Bhagavatam is transcendental to all of them because it has nothing to do with anything mundane. So the inquiries are very intelligent and relevant.
