The beginning of this post can be found in: Passover Is A Reminder Of The Future.
Pesach symbolizes the birth of the Israeli nation, which was born out of unity and despite repulsion. As long as we are divided and separated, we are not a nation, but are in exile. Only the good connection and unity between us makes us one community, which is rightly called “Israel.”
When we prepare for this ascent, we clean our homes and we break away from disputes and from being divided. The Seder symbolizes the order of the renewal of our corrupt mutual connections.
When we rid ourselves of this egoistic sourdough, we eat Matzo (unleavened bread) for seven days as a symbol of our ascent to the level of mutual bestowal, which in Egypt was perceived as tasteless. We start off along this path as slaves of separation, as slaves of our nature, and we end the journey as free people, freeborn, and as one nation.
It isn’t at all surprising that we have to relinquish our worship of the values that separate us, no matter where we live. Every such urge becomes a phase of the exodus from Egypt, since Pesach symbolizes our “step over” (Passover) the dispute and the separation towards the level of love.
