8.16 All the worlds, from the realm of Brahma included in the Brahmanda (cosmic sphere), are spheres in which experiences conferring Aisvarya (prosperity and power) can be obtained. But they are destructible and those who attain them are subject to return. Therefore destruction, i.e., return is unavoidable for the aspirants for Aisvarya, as the regions where it is attained perish. On the contrary there is no rirth to those who attain Me, the Omniscient, who has true resolves, whose sport is creation, sustentation and dissolution of the entire universe, who is supremely compassionate and who is always of the same form. For these reasons there is no destruction in the case of those who attain Me.

He now elucidates the time-period settled by the Supreme Person's will in regard to the evolution and dissolution of the worlds upto the cosmic sphere of Brahma and of those who are within them.
