Get used to a rough life, for luxury does not last forever.

That which you do not wish for yourself, do not impose on others.

For those who practise tyranny and deprive others of their rights, I will be harsh and stern, but for those who follow the law, I will be most soft and tender.

Lower your gaze from the world and turn your heart away from it...

The happiest of people is the one under whose care people are happy because of him, and the most miserable of people is the one under whose care people are miserable because of him.

Fear him, whom you hate.

Acquire knowledge and teach it to people.
