Childrens' book philosophy 13: Oscar Wilde on Sufism

"Be happy," cried the Nightengale, "be happy; you shall have your red rose. I will build it out of music by moonlight, and stain it with my own heart's blood. All that I ask of you in return is that you will be a true lover, for Love is wiser than Philosophy, though she is wise, and mightier than Power, though he is mighty." [...] The Student looked up from the grass, and listened, but he could not understand what the Nightengale was saying to him, for he only knew the things that are written down in books.

From Oscar Wilde, "The Selfish Giant"
