Ocean

Ah, ocean -
heaving grey-green mystery,
wine-dark in your hidden depths
where all is black abyss filled with hidden lights,
I have seen you opaque olive,
filled with the silt of ages,
diamond scattered when the light is right,
crystal clear blue sometimes,
making the heart ache
in your perfection
and immensity,
foaming wall of water sweeping all away,
indescribable cradle of life.
