We can only guess at what was revealed during the Eleusinian mysteries Mysteries since none of the initiates ever broke their oath, but whatever it was, it gave them hope for a better life, in this one and the next. Hadestown does this too.

It reminds us that we should still try, and have hope, and fight, even if we fail. Hadestown is inspirational, and even though it's a tragedy, we sing it again and again. Every time we see the musical, are we not inspired and moved by the end?
