Enigma

It says so much, the silence out there;
it speaks in volumes, the emptiness
and whispers in the cobalt waves.
Look beneath the surface,
seek and you will find
God's casket of treasures, once open
takes you to its heart and fills your mind.
It gives and yet retains its beauty;
the gentleness.
Molten, melting sunrays soothe
while they bathe the sands beneath
with slumbering breath.

Who holds the golden key?
