Man's expenses are the species profits

 The bottom line shows what you achieve,
The top line shows what we all believe.

The bottom line tells of your deeds,
The top line tells of our shared needs.

The bottom line marks your own way,
The top line marks how we all sway.

The bottom line shows your own might,
The top line shows our collective light.

The bottom line is your own quest, 

The top line is how we all do our best.
