Daigu Riokan (“Great Goof” or “Big Fool”) became enlightened and decided not to take students but to live as a hermit and subsist on alms. Consequently, he was very, very poor.
However, that’s not the end of the story.
One day a thief broke into his hut, and finding nothing worth stealing, trashed the place. Finding this, Daigu Riokan wrote this haiku —
The thief left it there,
there in the window —
the shining moon.
