Stoic Snippets 99

I consist of a little body and a soul. Now to this little body all things are indifferent, for it is not able to perceive differences. 

But to the understanding those things only are indifferent which are not the works of its own activity. But whatever things are the works of its own activity, all these are in its power. 

And of these, however, only those which are done with reference to the present; for as to the future and the past activities of the mind, even these are for the present indifferent.

—Marcus Aurelius, Meditations 6.32
