Marcus Aurelius
Meditations 12.3
The things are three of which thou art composed: a little body, a little breath [life], intelligence. Of these the first two are thine, so far as it is thy duty to take care of them; but the third alone is properly thine. Therefore if thou shalt separate from thyself, that is, from thy understanding, whatever others do or say, and whatever thou hast done or said thyself, and whatever future things trouble thee because they may happen, and whatever in the body which envelops thee or in the breath [life], which is by nature associated with the body, is attached to thee independent of thy will, and whatever the external circumfluent vortex whirls round, so that the intellectual power exempt from the things of fate can live pure and free by itself, doing what is just and accepting what happens and saying the truth: if thou wilt separate, I say, from this ruling faculty the things which are attached to it by the impressions of sense, and the things of time to come and of time that is past, and wilt make thyself like Empedocles' sphere,
"All round and in its joyous rest reposing;"
and if thou shalt strive to live only what is really thy life, that is, the present,—then thou wilt be able to pass that portion of life which remains for thee up to the time of thy death free from perturbations, nobly, and obedient to thy own daemon [to the god that is within thee].
Marcus Aurelius, Meditations 12.3, translated by George Long
Thou art formed of three things in combination—body, vital breath, intelligence. Of these the first two are indeed thine, in so far as thou must have them in thy keeping, but the third alone is in any true sense thine. Wherefore, if thou cut off from thyself, that is from thy mind, all that others do or say and all that thyself hast done or said, and all that harasses thee in the future, or whatever thou art involved in independently of thy will by the body which envelopes thee and the breath that is twinned with it, and whatever the circumambient rotation outside of thee sweeps along, so that thine intellectual faculty, delivered from the contingencies of destiny, may live pure and undetached by itself, doing what is just, desiring what befalls it, speaking the truth—if, I say, thou strip from this ruling Reason all that cleaves to it from the bodily influences and the things that lie beyond in time and the things that are past, and if thou fashion thyself like the Empedoclean
Sphere with its circle true in its poise well-rounded rejoicing,
and school thyself to live that life only which is thine, namely the present, so shalt thou be able to pass through the remnant of thy days calmly, kindly, and at peace with thine own ‘genius.'
