Wrong Desire is the Source of Suffering‎

"[...] They shed their sense of responsibility
Long ago, when they lost their votes, and the bribes; the mob
That used to grant power, high office, the legions, everything,
Curtails its desires, and reveals its anxiety for two things only,
Bread and circuses."

"So is there nothing worth people praying for? If you'll take
My advice, you'll allow the gods to determine what's right
For us, and what's likely to benefit our situation; for
The gods grant us gifts that are more fitting than nice.
They show more care for us than we do for ourselves. We
Seek marriage and offspring driven by blind emotion, by
Vain desire, while the gods know all about the children
We'll have, and what kind of wife ours will turn out to be.
Still, if you want a reason for prayer, for offering a pretty
White piglet's innards, the sacred sausages, at the shrines,
Then you might pray for a sound mind in a healthy body.
Ask for a heart filled with courage, without fear of death,
That regards long life as among the least of nature's gifts,
That can endure any hardship, to which anger is unknown,
That desires nothing, and gives more credit to all the labours
And cruel sufferings of Hercules, than to all the love-making
All the feasting, and all the downy pillows of Sardanapalus.
The prayer I offer you can grant yourself; without doubt,
The one true path that leads to a tranquil life is that of virtue.
If we were prudent, you'd possess no power, Fortune[!]: it's we
Who make you a goddess, and grant you a place in the sky."
