Meditations, Book III, Section 10

Meditations, Book III, Section 10:

Use thine opinative faculty with all honour and respect, for in her indeed is all: that thy opinion do not beget in thy understanding anything contrary to either nature, or the proper constitution of a rational creature. The end and object of a rational constitution is, to do nothing rashly, to be kindly affected towards men, and in all things willingly to submit unto the gods. Casting therefore all other things aside, keep thyself to these few, and remember withal that no man properly can be said to live more than that which is now present, which is but a moment of time. Whatsoever is besides either is already past, or uncertain. The time therefore that any man doth live, is but a little, and the place where he liveth, is but a very little corner of the earth, and the greatest fame that can remain of a man after his death, even that is but little, and that too, such as it is whilst it is, is by the succession of silly mortal men preserved, who likewise shall shortly die, and even whiles they live know not what in very deed they themselves are: and much less can know one, who long before is dead and gone. 

Meditations, Book III, Section 3

Meditations, Book III, Section 3:

Hippocrates having cured many sicknesses, fell sick himself and died. The Chaldeans and Astrologians having foretold the deaths of divers, were afterwards themselves surprised by the fates. Alexander and Pompeius, and Caius Caesar, having destroyed so many towns, and cut off in the field so many thousands both of horse and foot, yet they themselves at last were fain to part with their own lives. Heraclitus having written so many natural tracts concerning the last and general conflagration of the world, died afterwards all filled with water within, and all bedaubed with dirt and dung without. Lice killed Democritus; and Socrates, another sort of vermin, wicked ungodly men. How then stands the case? Thou hast taken ship, thou hast sailed, thou art come to land, go out, if to another life, there also shalt thou find gods, who are everywhere. If all life and sense shall cease, then shalt thou cease also to be subject to either pains or pleasures; and to serve and tend this vile cottage; so much the viler, by how much that which ministers unto it doth excel; the one being a rational substance, and a spirit, the other nothing but earth and blood.

Meditations, Book II, Section 15

Meditations, Book II, Section 15:

The time of a man's life is as a point; the substance of it ever flowing, the sense obscure; and the whole composition of the body tending to corruption. His soul is restless, fortune uncertain, and fame doubtful; to be brief, as a stream so are all things belonging to the body; as a dream, or as a smoke, so are all that belong unto the soul. Our life is a warfare, and a mere pilgrimage. Fame after life is no better than oblivion. What is it then that will adhere and follow? Only one thing, philosophy. And philosophy doth consist in this, for a man to preserve that spirit which is within him, from all manner of contumelies and injuries, and above all pains or pleasures; never to do anything either rashly, or feignedly, or hypocritically: wholly to depend from himself and his own proper actions: all things that happen unto him to embrace contentedly, as coming from Him from whom he himself also came; and above all things, with all meekness and a calm cheerfulness, to expect death, as being nothing else but the resolution of those elements, of which every creature is composed. And if the elements themselves suffer nothing by this their perpetual conversion of one into another, that dissolution, and alteration, which is so common unto all, why should it be feared by any? Is not this according to nature? But nothing that is according to nature can be evil, whilst I was at Carnuntzim.

Emphasis mine.
