PURPORT

By mentioning what was spoken to Maharaj Parikshit and which is very dear to the pure devotees means Srimad Bhagwatam. Srimad Bhagwatam is mainly full of the narrations in respect of the activities of the Supreme unlimited and therefore it is the science of Bhaktiyoga or devotional service of the Lord. As such it is para or the supreme because although it is enriched with all knowledge and religiosity specifically it is enriched with devotional service of the Lord.
