ayuh param idam smrtam
paresam gatim acaksva
ye syuh kalpad bahir vidah
vidurah uvaca--Vidura said; pitr--the Pita planets; deva--the heavenly planets; manusyanam--and that of the human beings; ayuh--duration of life; param--final; idam--in their own measurement; smrtam--calculated; paresam--of the superior living entities; gatim--duration of life; acaksva--kindly calculate; ye--all those who; syuh--are; kalpat--from the millennium; bahih--outside; vidah--greatly learned.
Vidura said: I now understand the life durations of the residents of the Pita planets and heavenly planets as well as that of the human beings. Now kindly inform me of the durations of life of those greatly learned living entities who are beyond the range of a kalpa.
The partial dissolution of the universe that takes place at the end of Brahma's day does not affect all the planetary systems. The planets of highly learned living entities like the sages Sanaka and Bhrgu are not affected by the dissolutions of the millenniums. All the planets are of different types, and each is controlled by a different kala-cakra, or schedule of eternal time. The time of the earth planet is not applicable to other, more elevated planets. Therefore, Vidura herein inquires about the duration of life on other planets.
