Is the wave, the water being shattered?

Or is it really the rock that is shattered, bit by bit, over time?

Stone shaped heart

your heart is an agate
clear stone

you have won
sort of
you think

but I am water
I am waves
I will smash you against the other rocks
and wear you down

I am water
I carve you like a laser
you wear my name
carved in your stone shaped heart

it is already written there
on your stone shaped heart
faint, because water wears slowly

water wearing stone
over time
