Never a mouse
  chases ever a tail,
  never a mouse ever sees
  that always a cat
  catches always a mouse,
  cats being kittens
  who once chased their tails.
  Toss a pebble into a stream,
  never a circle catches a circle;
  shoot a dawn-ball
  into the sky,
  never a moonbeam
  catches a sun;
  drop the same thought
  on the floor:
  Only a kitten catches a tail,
  the tail being straight,
  the kitten a circle.
  Yet never a mouse
  chases ever a tail,
  never a mouse ever sees
  that always some death
  catches always his mouse,
  deaths being kittens
  who once chased their tails.
