Two lips are as two lips do
One is one plus one is two
Two minds mean four lips
One plus one is one eclipse

An eclipse is an astronomical event that occurs when one celestial object moves into the shadow of another.

Two heavenly bodies
Orbiting a yellow dwarf
I am but a satellite
To your world

Plunged into stellar darkness
As you cross my path
Eclipsed by you, bright planet
Planet of millions of beautiful things.
