Freedom means doing the right thing even when it may not be socially popular. I have to live with my own conscience. The reality is liberating.

The Seder is the only one of the 613 mitzvot that is performed specifically at night, for on Passover, we turn the darkness into light. Song is the expression of an excited soul. It is the way to break out of oneself and reach for freedom. Every synagogue in the world faces Jerusalem. The Talmud says creation began in Jerusalem, and the world radiated outward from this spot.
