Sbg 8.19 etassa
English Translation of Abhinavgupta's Sanskrit Commentary By Dr. S. Sankaranarayan 8.17-19 Sahasra-etc., upto aharagama. Those who could see afar (great seers), see [actually] the night and day even in the case of Brahma as being marked [respectively] by the destruction and creation [of the world]. Accordingly, having risen from sleep, the same [Selves] continue their own respective activities every day; they theyselves, putting an end to their activities every night, remain exclusively in the form of Energy [of the Absolute]. In this manner they come to be again and again at the time of creation and of dissolution. No new, but only the self-same personal Souls are let loose. Their mutual difference in the form of the idea of the long and short lives is based only on the concept of time. This delimitation is unavoidable even in the case of the Prajapatis. Hence it is established that they too are cetainly of the nature of having evolution and dissolution.
[The Lord] clarifies His [own] statement : 'People do return from each and every world; but having attained Me, the Supreme Lord, they do not do so.'
