Into the Unknown

Into the blackness of night
I swim on.
Not knowing if it is night or
am I blind?
Have I swam into depths that
no light can penetrate?
Yet I swim on.
I can not know for sure
what lies ahead.
As I swim into the gloom as
black as pitch .
What life is there here,
if any ?
Yet I swim on.
It is all I know.
So I swim on until
I am no more.
