Sphere.

On the surface a horizon
Casts sly glances your way;
The same in every direction
Receding at your touch
Like magnetic forces
And perfect points.

Water knows this shape
Wanting to conserve itself
Time and space balanced
In that momentary fall
When gravity insists
And Earth prevails.

Funny little mathematics
Sets the rules in motion
and travels a line
infinite yet bound;
Symbols like notes
In the music
Of the mind.
