Meditations 5:13

I am made up of substance and what animates it, and neither one can ever stop existing, any more than it began to.

Every portion of me will be reassigned as another portion of the world, and that in turn transformed into another. Ad infinitum.

I was produced through one such transformation, and my parents too, and so on back. Ad infinitum.

N.B.: Still holds good, even if the world goes through recurrent cycles.
