The Bhagavata is one of the eighteen Mahapuranas. Of the innumerable collections of spiritual teachings found in Vedic literature, Srimad-Bhagavatam is considered the topmost. Vedic literature is sometimes said to be a “desire tree,” a tree that can yield whatever one might desire, and of that tree the Srimad-Bhagavatam is said to be the ripe and most relishable fruit.
The Bhagavatam's eighteen thousand verses contain hundreds of conversations between self-realized kings, yogis and sages of the ancient world on the subject of how to achieve perfection in life, including descriptions of various incarnations and activities of Krishna—the Supreme Person—and His devotees throughout history. It was compiled by Vyasadeva—editor of the Vedas—as his own commentary on Vedanta-sutra, the essence of all theistic knowledge.
