Parsha Mitzvot: Bo: Hiding The Afikoman
It is said in the name of the Brisker Rav, Rabbi Chaim Soloveitchik, that the reason we hide the Afikoman is to remember how carefully people would guard and hide the meat of the Korban Pesach – the Paschal Offering – to protect its purity.
Pesach is a time when we can use the laws of cleaning, searching and preparation to perfect our spiritual quests. The lesson of the Afikoman is that we must recognize that which is holy and do all we can to safeguard it.
