But if, in addition, you would like an unphilosophical rule which appeals to the heart, nothing will make you more cheerful in the face of death than to consider the things from which you are about to be parted, and the sort of characters with whom your soul will no longer be entangled.

[Εἰ δὲ καὶ ἰδιωτικὸν παράπηγμα ἁψικάρδιον θέλεις, μάλιστά σε εὔκολον πρὸς τὸν θάνατον ποιήσει ἡ ἐπίστασις ἡ ἐπὶ τὰ ὑποκείμενα, ὧν μέλλεις ἀφίστασθαι, καὶ μεθ̓ ἠθῶν οὐκέτι ἔσται ἡ … ἐμπεφυρμένη.]

Marcus Aurelius (AD 121-180) Roman emperor (161-180), Stoic philosopher

Meditations [To Himself; Τὰ εἰς ἑαυτόν], Book 9, ch. 3 (9.3) (AD 161-180) [tr. Hard (1997 ed.)]
    (Source)

Hard gives the same translation in their 2011 edition.(Source (Greek)). Alternate translations:

But thou desirest a more popular, and though not so direct and philosophical, yet a very powerful and penetrative recipe against the fear of death, nothing can make they more willing to part with thy life, than if thou shalt consider, both what the subjects themselves are that thou shalt part with, and what manner of disposition thou shalt no more have to do with.
[tr. Casaubon (1634)]

But if you stand in need of a Vulgar Remedy, and want a Cordial to make Dying go down the better, you shall have it. Consider then what sort of World, and what sort of Humours, you will be Rid of!
[tr. Collier (1701)]

If you want also a popular support, here is one which goes to the heart: you will be extremely easy with regard to death, if you consider the objects you are going to leave; and the manners of that confused croud from which you are to be disengaged.
[tr. Hutcheson/Moor (1742)]

But (if you would have a popular remedy, yet what may prove a cordial, against the fear of death) it will greatly contribute to this end, if you consider what sort of world you are to leave, and with what sort of characters you will no longer be conversant.
[tr. Graves (1792)]

But if thou requirest also a vulgar kind of comfort which shall reach thy heart, thou wilt be made best reconciled to death by observing the objects from which thou art going to be removed, and the morals of those with whom thy soul will no longer be mingled.
[tr. Long (1862)]

But if you stand in need of a vulgar remedy to soothe the mind, consider, then, what sort of world and what sort of customs you will be rid of!
[tr. Collier/Zimmern (1887)]

If your heart asks for some simple and effective reassurance, the best solace against death is correct appreciation of the material things from which you are to part, and of the moral natures with which your soul will then cease to intermingle.
[tr. Rendall (1898)]

If you wish for the common sort of comfort, here is a thought which goes to the heart. You will be completely resigned to death if you consider the things you are about to leave, and the morals of that confused crowd from which your soul is to be disengaged.
[tr. Hutcheson/Chrystal (1902)]

But if thou desirest a commonplace solace too that will appeal to the heart, nothing will enable thee to meet death with equanimity better than to observe the environment thou art leaving and the sort of characters with whom thy soul shall no longer be mixed up.
[tr. Haines (Loeb) (1916)]

And if you would have an everyday rule to touch your heart, it will make you most contented with death to dwell upon the objects from which you are about to be parted and the kind of characters with whom your soul will be no longer contaminated.
[tr. Farquharson (1944)]

But if your heart would have comfort of a simpler sort, then there is no better solace in the face of death than to think on the nature of the surroundings you are leaving, and the characters you will no longer have to mix with.
[tr. Staniforth (1964)]

Or perhaps you need some tidy aphorism to tuck away in the back of your mind. Well, consider two things that should reconcile you to death: the nature of the things you’ll leave behind you, and the kind of people you’ll no longer be mixed up with.
[tr. Hays (2003)]

If you want another criterion — unscientific but emotionally effective — you will find it quite easy to face death if you stop to consider the business you will be leaving and the sort of characters which will no longer contaminate your soul.
[tr. Hammond (2006)]

If you want a private passage at hand to soothe your heart, the knowledge of the world around you will give you some solace at death, the world you leave and the kind of people your soul will no longer be associated with.
[tr. @sentantiq (2017)]

If a person waiting for death should require some vulgar comfort, they can be more reconciled to death by remembering the evils from which they will be removed, and the morals of those they will no longer have to live with.
[tr. McNeill (2019)]
