In this shiur, delivered to the Chizzuk Mission in Aish HaTorah, Rav Burg explains how even though we remained servants of Achashverosh (which is why we don't say Hallel), we still celebrate Purim because we found the joy within our state of incompleteness. True joy comes from finding the completion within the incompletion. But there is great vulnerability in admitting that we are incomplete and that takes a tremendous amount of honesty and courage.
