The days of life pass away like clouds, so do good while you are alive.
Many a spoken word is more piercing than an attack.
Man comes from a drop of semen and leaves as a piece of dust. He doesn't know when he came and he doesn't know when he's leaving, yet he walks on the earth thinking he knows everything.
Do not be too hard, lest you be broken; do not be too soft, lest you be squeezed.
He who understands humanity seeks solitude
The highest person is he who is of most use to humankind.
