Indeed, according to the Rambam, it implies that one needs to see themselves as if they just left Egypt, meaning even in their physical body. Therefore, the Rambam's version states "to show oneself" through the actions of the Passover Seder, because it is impossible to fulfill this requirement through thought alone. The Abarbanel explains similarly to the Rambam, and yet he follows our custom's wording, which is, "In every generation, a person must see themselves as if they personally left Egypt." This means that one should see and consider themselves as if they were a slave who left Egypt for freedom. This is what the verse means when it says, "And you shall remember that you were a slave in Egypt," as if you were yourself a slave and were redeemed. We do not say "to show," but rather "to see" oneself, as is also found in the order of Rav Amram, may he rest in peace.

The Vilna Gaon used to say that fulfilling the obligation to see oneself as if they literally left Egypt, according to the Rambam's approach, is one of the most difficult things for him. The Eastern witnesses follow the Rambam's approach that one must act as if they left Egypt, and some of them hold a beautiful custom where the father stands at the entrance of the house with matzot on his shoulder, and his wife asks: "From where are you coming?" And he answers: "From Egypt."
