Square Root of None

I'm eyes wide shut proficient
Fill my cup
Sufficiently light outside for vision
Rip, twist, pull

In divisions of five plus one
Invisible lines, square root of none
I'd calculate fine art but I can't
A pictograph printed back to front
Well, wrong rings right
In role reversal
The ink won't dry
And wrong design

Got foresight delivering
But I'm one step wide
A gift or sign, and it's about time
In torchlight, envisaging
But I'm one step behind
It's slump or climb
In divisions of five

So you've got the selfish gene
And poor personality
I box it up, weight by tonne
A prism of useless stuff
In divisions of five plus one
Invisible lines, square root of none
A pity but foresight delivering
But I'm one step wide

A gift or sign
And it's about time
In torchlight, envisaging
But I'm one step behind
It's slump or climb
A divisions of five

I'm in a strange loop of zero
A time shift, a post-script
A hard thing to decode
It's slump or climb
In divisions of five
