Meditations 9.31

Let there be freedom from perturbations with respect to the things which come from the external cause; and let there be justice in the things done by virtue of the internal cause, that is, let there be movement and action terminating in this, in social acts, for this is according to thy nature.

Marcus Aurelius, Meditations 9.31, translated by George Long

Freedom from perturbance in all that befalls from the external Cause, and justice in all that thine own inner Cause prompts thee to do; that is, impulse and action finding fulfilment in the actual performance of social duty as being in accordance with thy nature.

Marcus Aurelius, Meditations 9.31, translated by C. R. Haines
