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
