Here you will find the Poem Book Of Parables - Bulbul's Song of poet Johann Wolfgang von Goethe
BULBUL'S song, through night hours cold, Rose to Allah's throne on high; To reward her melody, Giveth he a cage of gold. Such a cage are limbs of men,-- Though at first she feels confin'd, Yet when all she brings to mind, Straight the spirit sings again.
