Mbh 12.303.1

"'Yudhishthira said, "What is that which is called Undeteriorating and by attaining to which no one has to come back? What, again, is that which is called Deteriorating, and by attaining to which one has to return once more? O slayer of foes, I ask thee the distinction that exists, O thou of mighty arms, between the Deteriorating and the Undeteriorating ones for understanding them both truly, O delighter of the Kurus. Brahmanas conversant with the Vedas speak of thee as an Ocean of knowledge. Highly-blessed Rishis and Yatis of high souls do the same. Thou hast very few days to live. When the Sun turns from the southern path for entering into the northern, thou shalt attain to thy high end. When thou shalt leave us, from whom shall we hear of all that is beneficial for us? Thou art the lamp of Kuru's race. Indeed thou art always blazing with the light of knowledge. O perpetuator of Kuru's race, I desire, therefore to hear all this from thee. Listening to thy discourses that are always sweet like nectar, my curiosity, without being satiated is always increasing!"
