"Like a tunnel that you follow
To a tunnel of it's own
Down a hollow to a cavern
Where the sun has never shone
Like a door that keeps revolving
In a half-forgotten dream
Or the ripples from a pebble
Someone tosses in a stream

Like a clock whose hands are sweeping
Past the minutes of its face
And the world is like an apple
Whirling silently in space
Like the circles that you find
In the windmills of your mind."
