Marcus Aurelius
Meditations 9.3
Do not despise death, but be well content with it, since this too is one of those things which nature wills. For such as it is to be young and to grow old, and to increase and to reach maturity, and to have teeth and beard and gray hairs, and to beget and to be pregnant and to bring forth, and all the other natural operations which the seasons of thy life bring, such also is dissolution. This, then, is consistent with the character of a reflecting man—to be neither careless nor impatient nor contemptuous with respect to death, but to wait for it as one of the operations of nature. As thou now waitest for the time when the child shall come out of thy wife's womb, so be ready for the time when thy soul shall fall out of this envelope. 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. For it is no way right to be offended with men, but it is thy duty to care for them and to bear with them gently; and yet to remember that thy departure will not be from men who have the same principles as thyself. For this is the only thing, if there be any, which could draw us the contrary way and attach us to life,—to be permitted to live with those who have the same principles as ourselves. But now thou seest how great is the trouble arising from the discordance of those who live together, so that thou mayst say, Come quick, O death, lest perchance I, too, should forget myself.
Marcus Aurelius, Meditations 9.3, translated by George Long
Despise not death, but welcome it, for Nature wills it like all else. For dissolution is but one of the processes of Nature, associated with thy life's various seasons, such as to be young, to be old, to wax to our prime and to reach it, to grow teeth and beard and gray hairs, to beget, conceive and bring forth. A man then that has reasoned the matter out should not take up towards death the attitude of indifference, reluctance, or scorn, but await it as one of the processes of Nature. Look for the hour when thy soul shall emerge from this its sheath, as now thou awaitest the moment when the child she carries shall come forth from thy wife's womb.
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. For while it is very far from right to be disgusted with them, but rather even to befriend and deal gently with them,.yet it is well to remember that not from men of like principles with thine will thy release be. For this alone, if anything, could draw us back and bind us to life, if it were but permitted us to live with those who have possessed themselves of the same principles as ours. But now thou seest how thou art driven by sheer weariness at the jarring discord of thy life with them to say: Tarry not, O Death, lest peradventure I too forget myself.
