Observe the movements of the stars as if you were running their courses with them, and let your mind constantly dwell on the changes of the elements into each other. Such imaginings wash away the filth of life on the ground.

We are born for cooperation, as are the feet, the hands, the eyelids, and the upper and lower jaws.

Is any man afraid of change? Why what can take place without change? What then is more pleasing or more suitable to the universal nature?

All things of the body stream away like a river, all things of the mind are dreams and delusion; life is warfare, and a visit to a strange land; the only lasting fame is oblivion.

Humans have come into being for the sake of each other, so either teach them, or learn to bear them.

Love only what befalls you and is spun for you by fate.

I am called to man's labour; why then do I make a difficulty if I am going out to do what I was born to do and what I was brought into the world for?
