Live 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 AureliusWhen men hate or blame you, or say hurtful things about you, look deeply into their hearts and see what kind of men they are. You'll see how unnecessary it is to strain after their good opinion. Yet you must still think kindly of them. they are your neighbors. The gods help them as they do you, by dreams and oracles, to win their hearts' desires.
Marcus Aurelius
