מוֹעֲדֵי ה' - פֶּסַח

The days of Nisan are days of repentance, like Tishrei (49). Nisan is the aspect of rectifying the covenant. Through joy, one draws the holiness and joy of Nisan throughout the entire year, meriting to rectify the covenant and be saved from nocturnal emission, G-d forbid (Part II, 5:10).

The Haggadah of Passover is a rectification of the covenant. Therefore, we recite the Haggadah in a loud voice, for the voice arouses understanding, and through this, one merits the revelation of understanding, which is the essence of redemption. For the exile in Egypt was due to a blemish in the covenant, which is a blemish in understanding. Also, the wine of the four cups is a rectification of understanding, which is the aspect of rectifying the covenant (Part I, 20:10).

On Passover, one cries out in prayer (201). Festivals and Holy Convocations
