It is no less ridiculous to be shocked by these things than it is to complain because you get splashed in the baths, or get shoved around in a public place, or that you get dirty in muddy places. What happens in life is exactly like what happens in the baths, in a crowd, or on a muddy road..... Life is not for delicate souls.
-Seneca, Letters to Lucilius
The gaping jaws of a lion, poison, and everything unpleasant- mud, thorns and so forth- are accessory consequences of these sacred and venerable things on high. Don't imagine, then, that these things are foreign to the principle that you venerate, but rather rise up by your rational power to the source of all things.
-Marcus Aurelius, The Meditations
