Every Jewish child knows that the reason we eat matzah on Pesach is that there was not ample time for their dough to rise as our ancestors were fleeing Mitzrayim. While this may be the manifestation on a physical level, Rav Avigdor Nebenzahl Shlit”a explains that there is an additional reason that we eat matza on a spiritual level. While the physical dough may not have become chametz, their spiritual “dough” almost became chametz. This refers to the fact that the Jewish nation fell to the depths of impurity and were saved just in time, avoiding spiritual extinction. For us, throughout the year, we are challenged by all of the impurity that surrounds us and that has penetrated into our mindsets. Pesach is the time when we celebrate our freedom. Just as Hashem saved us physically and spiritually in Egypt, it is our hope that we will be saved from the chametz that has permeated from society into our lives. Eating matza can therefore be an intensely spiritual experience.
