They say
you can’t get blood from a stone,
but there you are
grinding
and bleeding from the effort.
There you are
releasing your hard heart
and weeping change.
Oh sure,
it hurts to be stoned
It’ll kill you, if the impact
hits the right place,
but a bloody stone
is only a reminder
of your strength.
Stones were once mountains
Worn by time and pressure
your mountain has become a stone,
and from your tight grip
drips
blood.

Be careful of holding onto something too tightly, the saying goes, lest you and it collapse together.
“The more you tighten your grip, the more star systems will slip through your fingers…” 😉
