What do you think these song lyrics mean?

An official meaning would be nice if there is one, but if not speculation is fine. If anyone needs an MP3 it can be found here: http://www.megaupload.com/?d=LSOA0C0N

The song is Carbon by Tori Amos.

carbon made found her at the

end of a chain "time to race"

she said "race the downhill"

behind crystalline irises

loons can drive

where the world bleeds white

just keep your eyes on her

keep

don't look away

keep your eyes on her horizon

bear claw free fall

a gunner's view black and blue

shred in ribbons of lithium

blow by blow

her mind cut in sheets

layers deep now unravelling

just keep your eyes on her.

get me neil on the line

no i can't hold

have him read "snow glass apples"

where nothing is what it seems

"little sis you must crack this"

he says to me

"you must go in again carbon

made only wants to be unmade"

blade to ice it's

double diamond time

and keep your eyes on her

on her eyes on her horizon
