The bookend's embrace

Your mind, how it fascinates me,
Neurones a howling supernova
in the shadow of soil in your stare:
No darkness lingering there.

I lust at the dust caught in sunbeams:
running off with the heavy clunk of time,
carrying us into carbon and rust,
into that elderly, ageless earthly dust.

Oh life, it is hugged by darkness
Like my bookends embrace your stories:
A brief flame in a blanket of black,
while a secondhand turns us to ash.

Your mind, does it too sink to heady heights,
Just to delight in the madness of it all?
Neurones flashing in the silence of a cranium,
casting shadows, twisted and beautiful?
Or is there really no darkness
in your mind
at all?
