Rav Kook, in his innovative style, explains the necessity for modern man to clean his Chametz in order to achieve individual and national independence and freedom on Pesach. If it's so natural to want to improve, and this "evolution" is built-in to the essence of the world, what are the factors that hold us back from being free to be ourselves? The Rav analyzes the symbols of matzah, maror and their merger in the Korech sandwich, in conjunction with free will, as well as nationalism.
