Consider frequently the connection of all things in the universe and their relation to one another. For things are somehow implicated with one another, and all in a way friendly to one another.
Marcus AureliusWhen you have been compelled by circumstances to be disturbed in any manner, quickly return to yourself, and do not continue out of tune longer than the compulsion lasts. You will have increasing control over your own harmony by continually returning to it.
Marcus Aurelius
