Here is the shadow of truth, for only the shadow is true.
And the line where the incoming swell from the sunset Pacific
First leans and staggers to break will tell all you need to know
About submarine geography, and your father's death rattle
Provides all biographical data required for the Who's Who of the dead.
I cannot recall what I started to tell you, but at least
This could potentially be saying something about the simplicity of Gods love. And also how fragile death truly is. And by father Robert could be talking about God, for he is the one who accepts people into heaven and the rattle could symbolize​ the bible which is the biographical (data or written work dealing with a particular persons life) of heaven.
