What can I learn from this about Pesah?
The Holiday of Pesah is a special time set aside to recognize the difference between living a physical existence, and living a spiritual existence clothed in physical experience. When we eat on Pesah we don't feel satiated to show us that physicality itself isn't enough. The Matzah gives us a taste of spirituality, makes us hungry even starving for the spiritual part of our existence.
That's why, at the end of the seder, after we've eaten the afikoman and will eat no more, we pray "Next year in Yerushalayim rebuilt." After our physical hunger should be completely satiated and yet we still feel hunger, we recognize that that hunger is for spiritual fulfillment, the kind only possible in Jerusalem, in the Beit HaMikdash, together with all of Am Yisrael.
