Meditation 6.32
Marcus AureliusMeditationsBook 6.32
32. I am composed of body and spirit. Now to the body all things are indifferent, for it cannot distinguish them itself. And to the understanding all that are not its own activities are indifferent, and all that are its own activities are in its control. Even of these, however, it is concerned only about the present, for its future and past activities are themselves also at the present moment indifferent.
