Hassidout sur Les Psaumes 147:19

In every generation one is obligated see themselves as if they had personally left Egypt, etc, and after, the Haggadah says "and took us out". And it appears that it is through this that the faith that there is an Egypt in every generation is revealed. And the Maharal wrote that there is a general assumption that every one that was in the coming out of Egypt is obligated only to see as if they had come personally out of Egypt, see there. And one could say also as above, that it is through belief that one enters into the general assumption, and obviously, in the general assumption that there was a coming out of Egypt for the life-force point [that exists in every Jewish soul], that from there flows life to every Jewish person, and through faith we come to that. And after that [it is possible to] see oneself as if they came out of Egypt. And one knows and believes that the understanding that one has can only exist because of coming out of Egypt. And this is the explanation in the telling of the story of coming out of Egypt, even if we are all wise etc, since even if one is very wise and connected to God, one's life exists so he will know that all this is due to the coming out of Egypt, because in truth it is so, and one needs to clarify this through faith. And 'telling' really is 'clarifying' and 'revealing' since in every generation there is a coming out of Egypt, according to what is happening in that generation, and all this happened in the time of the Exodus. And according to a person's faith as if one came out, it is revealed in one's life, and one can feel the coming out of Egypt of this moment, and one is able to come out from their own constricted place [their Egypt].
