The cucumber is bitter? Then throw it out. There are brambles in the path? Then go around them. That's all you need to know. Nothing more. Don't demand to know "why such things exist." Anyone who understands the world will laugh at you, just as a carpenter would if you seemed shocked at finding sawdust in his workshop, or a shoemaker at scraps of leather left over from work.
Marcus AureliusThe healthy eye ought to see all visible things and not to say, I wish for green things; for this is the condition of a diseased eye.
Marcus AureliusFor nowhere either with more quiet or more freedom from trouble does a man retire than into his own soul, particularly when he has within him such thoughts that by looking into them he is immediately in perfect tranquility; and I affirm that tranquility is nothing else than the good ordering of the mind.
Marcus Aurelius
