Have you ever stopped to think

about the sand underfoot on a busy beach?

 unwanted particulates in stagnation

that lay only to be walked upon 

that rise only when grasped

that fall forgotten again

 are swept out by sea

 or flushed by rain

a handful of silt 

is at best unremarkable

but when lightning calls down 

and gives it no choice but to rise

even the coarsest and meanest sand

the most useless and forgettable granules

the grains that were once wholesome but are no more

all realize

 what they made this journey for
