Hallel Nirtzah—Reciting Hallel, psalms of praise; the promise that G‑d will accept our service

The list of the indicators of the order of the Seder includes 15 words. (Nirtzah is not counted, for it does not involve any activity on our part). Fifteen is numerically equivalent to G‑d’s name י-ה, which the sages of the Kabbalah associate with the Sefiros of Chochmah and Binah (wisdom and understanding).

This fact contains an allusion applicable in our divine service. Although the service of Pesach centers on faith and kabbalas ol (the acceptance of G‑d’s yoke) — qualities which transcend intellect — even these superrational qualities must be filtered through our minds, our “wisdom and understanding.” In this manner they become part of our thinking processes and subject to our conscious control (the Rebbe).1
