Hekayat 10 from Chapter 2 of Golestan of Saadi

Someone asked the one who had lost his son:

"O wise and noble elder,

You smelled his shirt from Egypt,

Why did you not see him in the well of Canaan?"

He replied: "Our state is like the lightning of the world,

Visible for a moment and hidden the next.

Sometimes we sit on the highest throne,

Sometimes we cannot see our own feet.

If the dervish remained in one state,

He would shake off both worlds from his hand."
