The Meaning of Mussaf
If we examine the Mussaf service of Pesach, we realize that it is all based on the longing for the Mussaf sacrifice that was offered in the Beit Hamikdash.
The inability to offer this additional sacrifice, greatly diminished the holiness of the day.
The dialogue we have between ourselves and Hashem, is the essence of the contents of this holiday prayer.
We begin by acknowledging that we were chosen from among the nations and we were sanctified with the Mitzvot. We were given special festivals meant for rejoicing.
But because of our sins, we were exiled from the Land, and we were unable to adequately fulfill our holiday obligations in our holy Temple.
We ask Hashem to speedily rebuild the Temple, and gather all of the Jews scattered around the world. We will then be able to celebrate the holiday as was intended.
We ask for the Kohanim and Leviim to return to their Temple duties and that we be able to go up to Jerusalem for the three pilgrimage festivals.
We recite the Mussaf prayer all of the time, without stopping to realize what we are asking for, in this prayer. Perhaps this realization will allow us to have better “Kavana” the next time this important prayer is recited.
