Cover art for A Book Unfinished lyrics by Iron & Wine

The only part I know for sure what it means is this:

"No more weeds left in your garden No more green and no more stone No more guilty left to pardon Only evil of your own"

What I got from it is that the person who the song is about, they problems that they're having is all of their own doing. The first three lines are saying that they've gotten everything and everyone out of the way that could be causing problems, when really it's themself. And the last line is self-explanatory.
