A quote
Let these be the objects of thy ordinary meditation: to consider, what manner of men both for soul and body we ought to be, whensoever death shall surprise us: the shortness of this our mortal life: the immense vastness of the time that hath been before, and will he after us: the frailty of every worldly material object: all these things to consider, and behold clearly in themselves, all disguisement of external outside being removed and taken away.
Marcus Aurelius·Meditations 12.6·trans. Long
