sargah pradhaniko ’gratah
The Bhagavatam explains how one can attain liberation at the time of death by practicing fixed meditation in yoga. It also contains a discussion between Narada and Brahma, an enumeration of the incarnations of the Supreme Personality of Godhead, and a description of how the universe was created in progressive sequence, beginning from the unmanifest stage of material nature.
Srila Visvanatha Cakravarti Thakura explains that it would be difficult to give a complete list of the numerous accounts and topics contained in the Srimad-Bhagavatam. Therefore it is understood that Suta Gosvami is merely summarizing the topics. We should not consider the topics he fails to mention here less important or superfluous, since every letter and word of Srimad-Bhagavatam is absolute, Krsna conscious sound vibration.
