Meditations 9:28

The world's cycles never change—up and down, from age to age.

Either the world's intelligence wills each thing (if so, accept its will), or it exercised that will once—once and for all—and all else follows as a consequence (and if so, why worry?).

One way or another: atoms or unity. If it's God, all is well. If it's arbitrary, don't imitate it.

The earth will cover us all, and then be transformed in turn, and that too will change, ad infinitum. And that as well, ad infinitum.

Think about them: the waves of change and alteration, endlessly breaking. And see our brief mortality for what it is.
