Marcus Aurelius
Meditations 12.1
All those things at which thou wishest to arrive by a circuitous road thou canst have now, if thou dost not refuse them to thyself. And this means, if thou wilt take no notice of all the past, and trust the future to providence, and direct the present only conformably to piety and justice. Conformably to piety that thou mayest be content with the lot which is assigned to thee, for nature designed it for thee and thee for it. Conformably to justice, that thou mayst always speak the truth freely and without disguise, and do the things which are agreeable to law and according to the worth of each. And let neither another man's wickedness hinder thee, nor opinion nor voice, nor yet the sensations of the poor flesh which has grown about thee; for the passive part will look to this. If, then, whatever the time may be when thou shalt be near to thy departure, neglecting everything else thou shalt respect only thy ruling faculty and the divinity within thee, and if thou shalt be afraid not because thou must some time cease to live, but if thou shalt fear never to have begun to live according to nature—then thou wilt be a man worthy of the universe which has produced thee, and thou wilt cease to be a stranger in thy native land, and to wonder at things which happen daily as if they were something unexpected, and to be dependent on this or that.
Marcus Aurelius, Meditations 12.1, translated by George Long
All those things, which thou prayest to attain by a roundabout way, thou canst have at once if thou deny them not to thyself; that is to say, if thou leave all the Past to itself and entrust the Future to Providence, and but direct the Present in the way of piety and justice: piety, that thou mayest love thy lot, for Nature brought it to thee and thee to it; justice, that thou mayest speak the truth freely and without finesse, and have an eye to law and the due worth of things in all that thou doest; and let nothing stand in thy way, not the wickedness of others, nor thine own opinion, nor what men say, nor even the sensations of the flesh that has grown around thee; for the part affected will see to that.
If then, when the time of thy departure is near, abandoning all else thou prize thy ruling Reason alone and that which in thee is divine, and dread the thought, not that thou must one day cease to live, but that thou shouldst never yet have begun to live according to Nature, then shalt thou be a man worthy of the Universe that begat thee, and no longer an alien in thy fatherland, no longer shalt thou marvel at what happens every day as if it were unforeseen, and be dependent on this or that.
