In memory of Rabbi Levi Yitzchok ben R' Zalman Yuda Deitsch OBM
At the close of Neila, after the Yom Kippur service, we declare "Shema Yisrael" and "G-d is the L-rd" - statements that emphasize the oneness of G-d with our material existence. This oneness will be realized as we conclude "Next year in Jerusalem," with the coming of the Redemption. Furthermore, as the Previous Rebbe explained, the intent of that statement is not that we must wait until next year for the Redemption to come. Instead, the Redemption will come immediately and, as a natural result, next year, we will celebrate the holiday in Jerusalem.
