In the circles of your mind..

"Like a tunnel that you follow to a tunnel of its 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!"
