Structure of the seder - Rashi’s simanim (114a)

The famous mnemonic 'Kadesh u-rchatz' does not appear in its full form in the Mishna or Babylonian Talmud. It is a memory aid created by the great Rishonim, primarily Rashi, to simplify remembering the order of events on Seder night. It details 15 stages, from Kiddush to 'Nirtzah'.

Rashi and his colleagues divided the Seder into two main parts, like 'gates'. The first gate, from 'Kadesh' to 'Rachtzah', sets the stage for the meal. The second gate, from 'Motzi' to 'Nirtzah', deals with the meal itself and its conclusion. Within this structure, there are three recurring foci: the Four Cups, eating matzah, and narrating the Exodus.

1. 1First Gate (Preparation for the Meal): Kadesh, U-rchatz, Karpas, Yachatz, Maggid, Rachtzah.
2. 2Second Gate (The Meal and Conclusion): Motzi, Matzah, Maror, Korech, Shulchan Orech, Tzafun, Barech, Hallel, Nirtzah.

The most central stage in the Seder, and perhaps in the entire Seder night, is 'Maggid'. This is the narration of the Exodus from Egypt, which constitutes the primary purpose of the entire night. Notice its placement in the siman: fifth out of fifteen, precisely before Rachtzah, which separates the preparation from the meal itself.

Rashi's siman is an excellent foundation, but the Haggadah itself is the complete text detailing all the stages. It contains the blessings, piyyutim (liturgical poems), and derashot (interpretations) that make up each stage. Understanding the siman allows us to navigate the Haggadah with confidence, always knowing where we are and what the purpose of the current stage is.

The better we understand the structure, the more deeply we can experience the Seder night. Every action gains meaning as part of a larger, significant whole.
