Mbh 12.341.1

Saunaka said, "How is that illustrious god, viz., the puissant Narayana who is fully conversant with the Vedas and their branches, at once the doer and the enjoyer of sacrifices? Endued with forgiveness, he has adopted, again, the religion of Nivritti (abstention). Indeed, it is that holy and puissant one who has himself ordained the duties of Nivritti. Why then has he made many of the deities the takers of shares in sacrifices which, of course, are all due to the disposition of Pravritti? Why has he again created some with a contrary disposition, for they follow the ordinances of the religion of abstention? Do thou, O Suta, dispel this doubt of ours. This doubt seems to be eternal and is connected with a great mystery. Thou hast heard all discourses on Narayana, discourses that are consistent with the (other) scriptures."[1843]
