But the strangest part of it all is the way in which a single thought, an idea, will live with a man while he works, and take new forms from year to year, and light up the things that he sees and hears, and lead his imagination by the hand into many wonderful and diverse regions. It seems to me that there am two ways in which you may give unity to a book of stories. You may stay in one place and write about different themes, preserving always the colour of the same locality. Or you may go into different places and use as many of the colours and shapes of life as you can really see in the light of the same thought. There is such a thought in this book. It is the idea of the search for inward happiness, which all men who are really alive are following, along what various paths, and with what different fortunes! Glimpses of this idea, traces of this search, I thought that I could see in certain tales that were in my mind,—tales of times old and new, of lands near and far away. So I tried to tell them, as best as I could, hoping that other men, being also seekers, might find some meaning in them. There are only little, broken chapters from the long story of life. None of them is taken from other books. Only one of them—the story of Winifried and the Thunder-Oak—has the slightest wisp of a foundation in fact or legend. Yet I think they are all true. But how to find a name for such a book,—a name that will tell enough to show the thought and yet not too much to leave it free? I have borrowed a symbol from the old German poet and philosopher, Novalis, to stand instead of a name. The Blue Flower which he used in his romance of Heinrich von Ofterdingen to symbolise Poetry, the object of his young hero’s quest, I have used here to signify happiness, the satisfaction of the heart. Reader, will you take the book and see if it belongs to you? Whether it does or not, my wish is that the Blue Flower may grow in the garden where you work. AVALON, December 1, 1902.
