“We are all chained to fortune: the chain of one is made of gold, and wide, while that of another is short and rusty.”
On Tranquility of the Mind
Context: We are all chained to fortune: the chain of one is made of gold, and wide, while that of another is short and rusty. But what difference does it make? The same prison surrounds all of us, and even those who have bound others are bound themselves; unless perchance you think that a chain on the left side is lighter. Honors bind one man, wealth another; nobility oppresses some, humility others; some are held in subjection by an external power, while others obey the tyrant within; banishments keep some in one place, the priesthood others. All life is slavery. Therefore each one must accustom himself to his own condition and complain about it as little as possible, and lay hold of whatever good is to be found near him. Nothing is so bitter that a calm mind cannot find comfort in it. Small tablets, because of the writer's skill, have often served for many purposes, and a clever arrangement has often made a very narrow piece of land habitable. Apply reason to difficulties; harsh circumstances can be softened, narrow limits can be widened, and burdensome things can be made to press less severely on those who bear them cleverly.

The Unicorn in Captivity (1955)
Context: Here sits the Unicorn;
Leashed by a chain of gold
To the pomengranate tree.
So light a chain to hold
So fierce a beast;
Delicate as a cross at rest
On a maiden's breast.
He could snap the golden chain
With one toss of his mane,
If he chose to move,
If he chose to prove
His liberty.
But he does not choose
What choice would lose.
He stays, the Unicorn,
In captivity.
