The Hidden Meaning Behind the Structure of the Seder

In each and every generation, a person is obligated to see himself as if he left Egypt.

This is the bread of destitution that our ancestors ate in the land of Egypt. Anyone who is famished should come and eat, anyone who is in need should come and partake of the Pesach sacrifice. Now we are here, next year we will be in the land of Israel; this year we are slaves, next year we will be free people.

The Pesach [passover] sacrifice that our ancestors were accustomed to eating when the Temple existed, for the sake of what [was it]? For the sake [to commemorate] that the Holy One, blessed be He, passed over the homes of our ancestors in Egypt, as it is stated (Exodus 12:27); "And you shall say: 'It is the passover sacrifice to the Lord, for that He passed over the homes of the Children of Israel in Egypt, when He smote the Egyptians, and our homes he saved.’ And the people bowed the head and bowed."

At all other times we slowly transition from lower to higher states of consciousness, but on Pesach we rapidly transition through varying states of consciousness. And this is the meaning of the verse that says that we left Egypt in "haste."
