visvatma bhagavan harih
yasya prasada-jo brahma
Sukadeva Gosvami said: This Srimad-Bhagavatam has elaborately described in various narrations the Supreme Soul of all that be — the Personality of Godhead, Hari — from whose satisfaction Brahma is born and from whose anger Rudra takes birth.
Srila Visvanatha Cakravarti Thakura has given a very elaborate summary of Srimad-Bhagavatam in his commentary on this verse. The essence of the great acarya’s statement is that unconditional loving surrender to the Supreme Lord, Krsna, as described by Sukadeva Gosvami, is the highest perfection of life. The exclusive purpose of Srimad-Bhagavatam is to convince the conditioned soul to execute such surrender to the Lord and go back home, back to Godhead.
