Fairy Song

What I am I must not show-
What I am thou couldst not know-
Something betwixt heaven and hell-
Something that neither stood nor fell -
Something that through thy wit or will
May work thee good-may work thee ill.
Neither substance quite, not, shadow,
Haunting lonely moor and meadow,
Dancing by the haunted spring,
Riding on the whirlwind's wing;
Aping in fantastic fashion
Every change of human passion,
While o'er our frozen minds then pass,
Like shadows from the mirror'd glass.
Wayward, fickle, is our mood,
Hovering betwixt bad and good,
Happier than brief-dated man,
Living ten times o'er his span;
Far less happy, for we have
Help nor hope beyond the grave!

Sir Walter Scott
