After Pariksit Maharaja presented his questions before Sukadeva Goswami, the great sage started to reply. In the first canto, Suta Goswami answers the questions of Saunaka Rishi, while in the second canto, the Same Suta Goswami narrates the conversation between Sukadeva Goswami and Maharaja Pariksit.
In the first canto, Vyasadeva started his recitation with the words “oṁ namo bhagavate vāsudevāya”, offering his respects to the Supreme Lord. Now, in the second canto, Sukadeva Goswami starts his recitation by uttering the same words. The word “Bhagavan” can sometimes be used in relation to an ordinary powerful person, but Vāsudevāya makes it clear who is being addressed, “Kṛṣṇa, the son of Vasudeva”.
