Meditations 7.33

About pain: the pain which is intolerable carries us off; but that which lasts a long time is tolerable; and the mind maintains its own tranquillity by retiring into itself, and the ruling faculty is not made worse. But the parts which are harmed by pain, let them, if they can, give their opinion about it.

Marcus Aurelius, Meditations 7.33, translated by George Long

Of Pain: When unbearable it destroys us, when lasting, it is bearable, and the mind safeguards its own calm by withdrawing itself, and the ruling Reason takes no hurt. As to the parts that are impaired by the pain, let them say their say about it as they can.

Marcus Aurelius, Meditations 7.33, translated by C. R. Haines
