The seventh and final days of Passover are the Comparing and Elevating of the holiday of Passover.
Passover signifies the first freedom, the exodus from Egypt, the redemption from Egypt. But not only that, Passover is also our freedom today; it is a special and opportune time for us, if we only desire, of course, to extricate ourselves from all that constrains and limits us from living as we truly wish to live, at our highest level, of ourselves.
When I say "us," I mainly refer to our holy soul.
Zalman Yaffe was a special Chasid who used to come every year for Shavuot from England to Brooklyn to be with the Rebbe. A special Chasid because unlike other Chasidim, Reb Zalman Yaffe spoke quite freely with the Rebbe, and the Rebbe, on his part, showed him special closeness.
After Shavuot of 1974 when he was about to bid farewell to the Rebbe towards his return to England, he told the Rebbe that he was very pleased with the blessing the Rebbe gave him the previous year and he wants to receive the same blessing this year.
The blessing was not ordinary; when the Rebbe blessed him, he suddenly added and said that the blessings would be "iber dem kop" in Yiddish, which translates to "over the head," and the implication is (I assume) that the blessing will be more than he can contain or more than he expects.
The Rebbe - as recounted by Zalman's grandson - seemed disappointed by the request and said to him in English: Have you no ambition?
What was good for last year is no longer enough for the next year. We are always required to advance further and upward. How is it that you are not aiming for more?
"Comparing and Elevating"
After the initial days of the holiday of freedom, after we began to deal with it with ourselves and collectively, and also asked and prayed for everyone, here come the final days of Passover, the seventh and last day of Passover, and they demand of us to aspire for more.
The seventh and last day of Passover signify both the conclusion of the holiday of Passover, the seal of the exodus from Egypt, but immediately and concurrently also elevate a stage towards the future redemption. We remember the exodus from Egypt and immediately request "as in the days of your exodus from the land of Egypt, I will show you wonders“ (Micha 7/15) in the future, final redemption, the one after which there will be no exile. We seek to complete the four cups and progress towards „VeHeveti - and I will bring you."
We will compare and elevate; tomorrow and the next day we will come from the exodus from Egypt and focus on the future redemption, the coming of our righteous Messiah.
