When a person learns sefarim hakedoshim before a Yom Tov, he thereby connects with the essence of what the Ribbono shel Olam wants him to derive from this Yom Tov. He has prepared his heart and mind for the upcoming Yom Tov: A Yom Tov of Pesach is coming up—a time when the Ribbono shel Olam took us out of Mitzrayim and demonstrated that He runs the world. Then, when the Yom Tov finally arrives, the heart and mind are open to receiving that aura of emunah, a clarity in emunah, and a strengthening in emunah. He has connected to the essence of the Yom Tov.
When this person consumes the matzah, he will have in mind the essence of the mitzvah of matzah—beyond the technicalities of the size of the matzah and the speed with which it must be eaten. These things are crucial, of course; a Yid must fulfill every aspect as stated in the Shulchan Aruch. But this Yid is primarily consumed with connecting to the essence of the mitzvah that he’s doing.
