Nature has made us passive, and to suffer is our lot. While we are in the flesh every man has his chain and his clog; only it is looser and lighter to one man than to another, and he is more at ease who takes it up and carries it than he who drags it.
Seneca the YoungerHappy is the man who can endure the highest and lowest fortune. He who has endured such vicissitudes with equanimity has deprived misfortune of its power.
Seneca the YoungerTo see a man fearless in dangers, untainted with lusts, happy in adversity, composed in a tumult, and laughing at all those things which are generally either coveted or feared, all men must acknowledge that this can be from nothing else but a beam of divinity that influences a mortal body.
