Like a circle in a spiral...

Round
Like a circle in a spiral
Like a wheel within a wheel
Never ending or beginning
On an ever-spinning reel
Like a snowball down a mountain
Or a carnival balloon
Like a carousel that’s turning
Running rings around the moon
Like a clock whose hands are sweeping
Past the minutes of it’s face
And the world is like an apple
Whirling silently in space
Like the circles that you find
In the windmills of your mind

The Windmills of Your Mind (1969)
Dusty Springfield
