Fortune

Oh, tell me what you're like
       A chameleon
Unceasingly changing?
       A wheel
Unceasingly rolling?
       A river
Unceasingly flowing?
       Air
Unceasingly blowing?
       The seasons
Unceasingly varying?
       The seas
Unceasingly surging?
       The earth
Unceasingly rotating?
       Unlike any of these?
Oh, Fortune, tell me what you're like!
