English Translation of Sanskrit Commentary By Sri Shankaracharya's
8.19 O son of Prtha, bhutva, after being born again and again at the approach of day; sah eva, that very-not any other; bhutagramah, multitude of beings, consisting of the moving and the non-moving objects that existed in the earlier cycle of creation; praliyate, disappears repeatedly; avasah, in spinte of itself, [For they are impelled by their own defects] without any independence whatever; ratri-agame, at the approach of night, at the close of the day. Prabhavati, it comes to life, verily in spite of itself; ahar-agame, at the approach of day.
The means for the attainment of that Immutable which was introduced has been pointed out in, He who departs by leaving the body while uttering the single syllable, viz Om, which is Brahman,  etc. (13). Now, with a vies to indicating the real nature of that very Immutable, this is being said-that It is to be reached through this path of yoga:


English Translation of Commentary  - 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.


English Translation of Ramanuja's Sanskrit Commentary
8.19 The same multitude of beings, controlled by Karma, evolves again and again, undergoing dissolution at the coming of night. Again at the coming of the day it comes forth. Similarly, at the end of the life span of Brahma which consists of a hundred years of three hundred and sixty days each, each Brahma-day being a thousand Caturyugas, all the worlds including that of Brahma and Brahma himself dissolve into Me in accordance with the order thus described in the Srutis:  The earth is dissolved into the waters, the waters are dissolved into light etc., (Su. U., 2). The process of involution ends, after passing through all the other stages of dissolution, with the Avyakta, Akasa and Tamas. Therefore, for every other entity except Myself, origination and annihilation are unavoidable. So for those who seek Aisvarya (prosperity and power) birth and dissolution according to the above mentioned time arrangement are unavoidable. But in the case of those who attain to Me, there is no return again to Samsara. [The immense duration of time, according to ancient thinkers, is as follows:  Catur-yuga, or a unit of the four yugas of Krta, Treta, Dvapara and Kali, has a cumulative duration of 4,320,000 human years. A thousand such periods constitute a day time of Brahma and a similar period his night. Periodic creation and dissolution of the universe take place in these two periods respectively. One year of Brahma consists of 360 such diurnal period. A Brahma has a life-span of 100 such years - i.e., 311, 040, 000,000,000 human years. At the end of it, there is a Mahapralaya, and a new Brahma comes into being. Time thus goes on endlessly].

Now Sri Krsna teaches that there is no return to Samsara even for those who have attained Kaivalya (isolation of the self).
