Haggadah-Shulchan Orech-Chernobyler Maggid
The 4th of Nisan is the Yahrtzeit of Rav Yochanan Twersky of Rachmistrivka (1816-1895), son of the Maggid of Chernobyl. The banquet which we choose gift to celebrate a mitzvah is more worthy than the mitzvah itself. A parable illustrates this:
The Satan brought many serious accusations against the Jews, and their defender, the Archangel Michael, knew of no arguments in their behalf. After a while he thought to himself and said, “The few mitzvot which Jews perform, offset their many transgressions. When a Jew performs a circumcision, he gives a banquet, because he is overjoyed at having done a mitzvah. Have you ever seen a Jew, however, celebrating when he transgresses? In the mitzvah he feels intense happiness this demonstrates that he feels no joy in his offense, and only succumbs because of weakness..”
This defense before the Heavenly Tribunal proved successful.
Hence you see, how important is the celebration of a mitzvah with a banquet! (Ateret haTzaddikim, page 17)
Use Shulchan Orech as a banquet to celebrate the Pesach Mitzvot.
