EVERYTHING CHANGES

Everything changes. You can make
A fresh start with your final breath.
But what has happened has happened. And the water
You once poured into the wine cannot be
Drained off again.

What has happened has happened. The water
You once poured into the wine cannot be
Drained off again, but
Everything changes. You can make
A fresh start with your final breath.

Ghost Light: An Introductory Handbook for Dramaturgy

I found these two books to be particularly helpful in learning dramaturgy. Ghostlight also has a section on different theories to use when analyzing a text. I was already familiar with these from my anthropology courses but the refresher was helpful. Ghostlight was also written cleanly and not bogged down with a lot of academic language which I found in other texts on theory. Both are from Southern Illinois University Press.
