On this daf, we find the teaching that various sages would use as a prelude when expounding the Megillah. Rav Gedaliah Schorr explains that each of these teachings is a key to understanding the Megillah. We require these keys to reveal the deep lessons the Megillah teaches us year after year. In the words of Rav Levi Yitzchok of Berditchev, “The miracle of Purim happened enrobed in nature. It therefore has the power to change nature. When we read the Megillah, our very natures are purified and refined, and a great illumination is imparted to the entire world. We perceive to the depths of our being that the world exists exclusively for Torah and mitzvos. One who reads or listens to the Megillah with kavanah will be filled with joy. He will be filled with yearning to learn Torah and fulfill the mitzvos with joy, just like they accepted the Torah from love in Achashveirosh’s times” (Kedushas Levi, Kedusha Rishonah).
