Say what you will of light

it has a will of its own
travels at one speed
defines the limits of time
and relentlessly calls up
the obvious to enlighten

It pierces even crevasses 
in the icy vaults of frozen souls
echoes itself in mirrors
shatters in the purity of prisms
that splinter its wavelengths
to sound in eyes the vibrating
brilliance of the world

and simultaneously
draws and ends the lives
of mothmen

It remains the true mother of visions
and is faintest in the minds
of the willfully blind
