The happiness of your life depends upon the quality of your thoughts: therefore, guard accordingly, and take care that you entertain no notions unsuitable to virtue and reasonable nature.
Marcus AureliusFailure to read what is happening in another's soul is not easily seen as a cause of unhappiness: but those who fail to attend the motions of their own soul are necessarily unhappy.
Marcus AureliusLive a good life. If there are gods and they are just, then they will not care how devout you have been, but will welcome you based on the virtues you have lived by. If there are gods, but unjust, then you should not want to worship them. If there are no gods, then you will be gone, but will have lived a noble life that will live on in the memories of your loved ones.
Marcus AureliusDo not fear death, but welcome it, since it too comes from nature. For just as we are young and grow old, and flourish and reach maturity, have teeth and a beard and grey hairs, conceive, become pregnant, and bring forth new life, and all the other natural processes that follow the seasons of our existence, so also do we have death. A thoughtful person will never take death lightly, impatiently, or scornfully, but will wait for it as one of life's natural processes.
Marcus AureliusHe who fears death either fears the loss of sensation or a different kind of sensation. But if thou shalt have no sensation, neither wilt thou feel any harm; and if thou shalt acquire another kind of sensation, thou wilt be a different kind of living being and thou wilt not cease to live.
Marcus Aurelius
