Meditations, Book IV, Section 3

I find this section to be very useful. Marcus here is agnostic on the nature of the universe, but says that the conclusion for how to live your life is the same. He points out how one should endure bad people, but also about how disputing or contending people all eventually die, how praise and blame are fickle and temporary, and if there is something that you hunger after, such as fame, that too is fleeting and will one day disappear.

Meditations, Book IV, Section 3:

They seek for themselves private retiring places, as country villages, the sea-shore, mountains; yea thou thyself art wont to long much after such places. But all this thou must know proceeds from simplicity in the highest degree. At what time soever thou wilt, it is in thy power to retire into thyself, and to be at rest, and free from all businesses. A man cannot any whither retire better than to his own soul; he especially who is beforehand provided of such things within, which whensoever he doth withdraw himself to look in, may presently afford unto him perfect ease and tranquillity. By tranquillity I understand a decent orderly disposition and carriage, free from all confusion and tumultuousness. Afford then thyself this retiring continually, and thereby refresh and renew thyself. Let these precepts be brief and fundamental, which as soon as thou dost call them to mind, may suffice thee to purge thy soul throughly, and to send thee away well pleased with those things whatsoever they be, which now again after this short withdrawing of thy soul into herself thou dost return unto. For what is it that thou art offended at? Can it be at the wickedness of men, when thou dost call to mind this conclusion, that all reasonable creatures are made one for another? and that it is part of justice to bear with them? and that it is against their wills that they offend? and how many already, who once likewise prosecuted their enmities, suspected, hated, and fiercely contended, are now long ago stretched out, and reduced unto ashes? It is time for thee to make an end. As for those things which among the common chances of the world happen unto thee as thy particular lot and portion, canst thou be displeased with any of them, when thou dost call that our ordinary dilemma to mind, either a providence, or Democritus his atoms; and with it, whatsoever we brought to prove that the whole world is as it were one city? And as for thy body, what canst thou fear, if thou dost consider that thy mind and understanding, when once it hath recollected itself, and knows its own power, hath in this life and breath (whether it run smoothly and gently, or whether harshly and rudely), no interest at all, but is altogether indifferent: and whatsoever else thou hast heard and assented unto concerning either pain or pleasure? But the care of thine honour and reputation will perchance distract thee? How can that be, if thou dost look back, and consider both how quickly all things that are, are forgotten, and what an immense chaos of eternity was before, and will follow after all things: and the vanity of praise, and the inconstancy and variableness of human judgments and opinions, and the narrowness of the place, wherein it is limited and circumscribed? For the whole earth is but as one point; and of it, this inhabited part of it, is but a very little part; and of this part, how many in number, and what manner of men are they, that will commend thee? What remains then, but that thou often put in practice this kind of retiring of thyself, to this little part of thyself; and above all things, keep thyself from distraction, and intend not anything vehemently, but be free and consider all things, as a man whose proper object is Virtue, as a man whose true nature is to be kind and sociable, as a citizen, as a mortal creature. Among other things, which to consider, and look into thou must use to withdraw thyself, let those two be among the most obvious and at hand. One, that the things or objects themselves reach not unto the soul, but stand without still and quiet, and that it is from the opinion only which is within, that all the tumult and all the trouble doth proceed. The next, that all these things, which now thou seest, shall within a very little while be changed, and be no more: and ever call to mind, how many changes and alterations in the world thou thyself hast already been an eyewitness of in thy time. This world is mere change, and this life, opinion.

An alternative translation:

Men seek retreats for themselves, houses in the country, sea-shores, and mountains; and thou too art wont to desire such things very much. But this is altogether a mark of the most common sort of men, for it is in thy power whenever thou shalt choose to retire into thyself. For nowhere either with more quiet or more freedom from trouble does a man retire than into his own soul, particularly when he has within him such thoughts that by looking into them he is immediately in perfect tranquility; and I affirm that tranquility is nothing else than the good ordering of the mind. Constantly then give to thyself this retreat, and renew thyself; and let thy principles be brief and fundamental, which, as soon as thou shalt recur to them, will be sufficient to cleanse the soul completely, and to send thee back free from all discontent with the things to which thou returnest. For with what art thou discontented? With the badness of men? Recall to thy mind this conclusion, that rational animals exist for one another, and that to endure is a part of justice, and that men do wrong involuntarily; and consider how many already, after mutual enmity, suspicion, hatred, and fighting, have been stretched dead, reduced to ashes; and be quiet at last.- But perhaps thou art dissatisfied with that which is assigned to thee out of the universe.- Recall to thy recollection this alternative; either there is providence or atoms, fortuitous concurrence of things; or remember the arguments by which it has been proved that the world is a kind of political community, and be quiet at last.- But perhaps corporeal things will still fasten upon thee.- Consider then further that the mind mingles not with the breath, whether moving gently or violently, when it has once drawn itself apart and discovered its own power, and think also of all that thou hast heard and assented to about pain and pleasure, and be quiet at last.- But perhaps the desire of the thing called fame will torment thee.- See how soon everything is forgotten, and look at the chaos of infinite time on each side of the present, and the emptiness of applause, and the changeableness and want of judgement in those who pretend to give praise, and the narrowness of the space within which it is circumscribed, and be quiet at last. For the whole earth is a point, and how small a nook in it is this thy dwelling, and how few are there in it, and what kind of people are they who will praise thee.
