     شبم ز روزن اگر ماه آسمان آید
     جهم ز جای تصور کنم که ماه منست

     šabam zi rōzan agar māh-i āsmān āyad
     jaham zi jāy tasawwur kunam ki māh-i man ast

     At night, if the moon of the heavens comes to me through the window,
     I leap forth from my place, imagining that it is my moon.
