Mbh 12.231.1

"'Yudhishthira said, "I desire, O thou of Kuru's race, to know what the origin and what the end is of all creatures; what is the nature of their meditation and what are their acts; what are the divisions of time, and what the allotted periods of life in the respective epochs. I desire also to know in full the truth about the genesis and the conduct of the world; the origin of creatures into the world and the manner of their going on. Indeed, whence their creation and destruction? O best of virtuous persons, if thou art minded to favour us, do tell us this about which I ask thee. Having heard before this excellent discourse of Bhrigu unto the regenerate sage Bharadwaja which thou didst recite, my understanding, purged of ignorance, has become exceedingly attached to yoga, and withdrawn from worldly objects rests upon heavenly purity. I ask thee about the subject, therefore, once more. It behoves thee to discourse to me (more elaborately)."
