PURPORT

Bhagavatam literally means the pastimes of the Lord and the Lord's devotees. For example, there are pastimes of Lord Krsna and narrations of devotees like Prahlada, Dhruva and Maharaja Ambarisa. Both pastimes pertain to the Supreme Personality of Godhead because the devotees' pastimes are in relation with Him. The Mahabharata, for example, the history of the Pandavas and their activities, is sacred because the Pandavas had a direct relationship with the Supreme Personality of Godhead.
