Meditations 2.9

This thou must always bear in mind, what is the nature of the whole, and what is my nature, and how this is related to that, and what kind of a part it is of what kind of a whole, and that there is no one who hinders thee from always doing and saying the things which are according to the nature of which thou art a part.

Marcus Aurelius, Meditations 2.9, translated by George Long

This must always be borne in mind, what is the Nature of the whole Universe, and what mine, and how this stands in relation to that, being too what sort of a part of what sort of a whole; and that no one can prevent thee from doing and saying always what is in keeping with the Nature of which thou art a part.

Marcus Aurelius, Meditations 2.9, translated by C. R. Haines
