Q: Why do we open the Seder night with questions?
A: The most severe and oppressive exile of the soul is when a person is so obstructed that he represses all his questions. Similarly, an oppressive regime will continue to rule as long as its subjects do not dare to open their mouths and ask questions. But when something is set free inside, we begin to ask: “Until when” and why? This is the first sign of rebellion against the evil regime. It is the beginning of liberty.
And when we receive a clear answer, that is the redemption, itself.
