Devibhagavatapurana 1.1.11

1.1.11

ataḥ sarve dvijāḥ saumya śrotukāmāḥ samāhitāḥ |
vartante naimiṣāraṇye kṣetre kalibhayārditāḥ ||

O Saumya! Hence all these Brâhmins, being distressed with the fear of this Kali, have come here to this Naimisâranya, eager to hear attentively the Purânas, and are staying here with this one object. Time must be spent away anyhow or other; those that are fools while away their times in sports and other evil practices and those that are learned pass away their times in meditating on the S’âstras; but these S’âstras are too vast and very varied; they contain Jalpas (debates or wrangling discussions to win over the opposite party), Vadas (sound doctrines to arrive at just conclusions), and various Arthavâdas (explanations and assertions, recommending Vidhis or precepts by stating the good arising from its proper observance and evils arising from its omission and also by adducing historical instances for its support; praises and eulogies) and filled with many argumentations. And, amongst these S’âstras again, the Vedânta is the Sâttvik, the Mimâmsas are the Râjasik and the Nyâya S’âstras with Hetuvâdas, are the Tâmasik; so the S’âstras are varied. Similarly, the Purânas are of three kinds:-- (1) S’attvik, (2) Râjasik and (3) Tâmasik. O Saumya! (one of gentle appearance) you have recited those Purânas endowed with five characteristics and full of many narratives; of these, the fifth Purâna, equivalent to the Vedas and with all the good qualities, the Bhâgavata yields Dharma and Kâma (religion and desires), gives liberation to those who desire for emancipation and is very wonderful; you mentioned this before but ordinarily; you did not dwell on this specially. Now these Brâhmanas are eager to hear gladly this divine auspicious Bhâgavata, the best of the Purânas; so kindly describe this in detail.
