suta jiva ciram sadho
vada no vadatam vara
tamasy apare bhramatam
nrnam tvam para-darsanah
Sri Saunaka said: O Suta, may you live a long life! O saintly one, best of speakers, please continue speaking to us. Indeed, only you can show men the path out of the ignorance in which they are wandering.
According to Srila Jiva Gosvami, the sages saw that Suta Gosvami was about to end his narration of Srimad-Bhagavatam, and thus they urged him to first tell the story of Markandeya Rsi.
