Meditation 5.24-25
Marcus AureliusMeditationsBook 5.24
24. Call to mind the whole of Substance of which you have a very small portion, and the whole of time whereof a small hair's breadth has been determined for you, and of the chain of causation whereof you are how small a link.
25. Another does wrong. What is that to me? Let him look to it; he has his own disposition, his own activity. I have now what Universal Nature wills me to have, and I do what my own nature wills me to do.
