All Vedic literatures maintain that Srimad-Bhagavatam has to be learned from the person bhagavata, and to understand it one has to engage in pure devotional service. Srimad-Bhagavatam cannot be understood by so-called erudite scholars or grammarians. One who has developed pure Krsna consciousness and has served the pure devotee, the spiritual master, can
understand Srimad-Bhagavatam. Others cannot.
