What is the book of Eikhah all about? What is its purpose? By closely examining Chapter 1 and viewing it in play form we notice that Eikhah is not a book of kinot, but rather a guide for Am Yisrael in the aftermath of the churban. It is meant to instruct the nation grappling with the social and psychological realities of rebuilding their lives, allowing them to realize that God is there and they can turn to Him during times of crisis.
