He follows the bird as it sings the most wonderful songs that the monk has ever heard, until finally it grows dark and he has wandered far from his home; the monk lies down to sleep and in the morning, the bird leads him back to the monastery.
On his return, the monk sees many changes and recognises no-one, so he asks one of the monks what has happened to the monastery. The man replies that nothing has been altered since the previous day and is very puzzled by the monk's question.
The monk then explains that he got lost in the woods following a marvellous song-bird. "Ah," says the other man, "there is an old story about an old monk just like you, who also followed a song-bird...but that was two hundred years ago!"
The monk realises that the story is about him and knows that his time is nearly at an end...the bird reappears and his last earthly memories are of his treasured garden and a bird of paradise singing.
