Answer: The night of the exodus from Egypt is a result of all previous development of Jews whereby they brought themselves to the state that allowed them to become a nation and understand that inside them is the ego, Pharaoh, that rips them apart, leads to the conflicts with each other, and makes them feel distant from each other.
Look what is happening around: discords in the family, society, and government. We would do anything in order to suppress an alleged enemy. We need to start feeling our state as Egypt, as the reign of the Pharaoh, meaning our egoism that prevents us from being one nation, one family. Precisely this is called night.
This is why on the Passover night we gather together with our families and consider ourselves as one family, one nation. We want to demonstrate that we are ready to unite, to be together with the aim of rising above our egoism and coming to the freedom from it. This is the exodus from Egypt and the entrance to the land of Israel.
Between them there is a period of 40 years of passing the desert whereby we correct ourselves. By this correction we prepare ourselves for the entrance to the land of Israel as we can’t go straight away from the egoism and hatred to love. After all, love is the same egoism just in a reversed form. And 40 years long periods of preparation represent a distance from the desire to receive to the desire to bestow, from hatred to love.
Egyptian night is a pitch dark, terrible night of an absolute lack of understanding of what is happening and what will happen. People see that because of the mutual hatred, they cease to exist as a nation, as a family. They understand that this dead-end state leads them to death.
But at the same time they don’t see the way out of it because the power of egoism seems to be historically eternal and absolute. In everything the person turns to he sees his egoism, and he feels that he does everything only for his own benefit. It controls our every action: internal, external, our relationships, etc.
Everyone keeps such a distance from another where he would be able to defend himself and to receive maximum from the other. It means that the egoism all the time regulates our relationships with each other, nature, animals, the world, and life.
The terrible state of communication only in an egoistic manner is revealed to us as the darkness of Egypt. Exactly in this state, in the middle of the night a force suddenly appears in us, which leads us forward to the exit from the egoism and gives us a feeling that we can rise from it.
A culminating point of inversion appears and the most terrible darkness suddenly starts transforming into some hope, light: An exit exists somewhere, I have to run! And I run after this dream, after this internal power that suddenly erupts in me. And the light appears!
It is a special night, the night of exiting the egoistic slavery to altruistic eternity and perfection. This is why we celebrate it.
