Write Me for the Generations
After the miracle, Esther asked the chachamim to set Purim and her book for all time, and would not accept their first refusal.
The Gemara relates that once the danger had passed, Esther turned to the future. She sent a request to the chachamim: establish me for the generations. She wanted the days of Purim and the reading of her story to become a permanent obligation for all of Israel.
The chachamim hesitated. If the story of the Jews' victory over their enemies is read in public every year, they answered, it will stir up the anger of the nations against us. Esther sent back a reply: I am already written in the chronicles of the kings of Media and Persia. The world knows the story; reading it will reveal nothing new.
She made a second request: write my book for the generations, as one of the Kisvei HaKodesh. Again the chachamim answered with a verse. Shlomo HaMelech wrote, Have I not written for you three times? The war with Amalek, they explained, is meant to be recorded three times in Tanach, and it already was. The chachamim did not grant her request until they found a verse in the Torah itself: Write this as a memorial in the book. Write this, they explained, is what is written in the Torah; a memorial is what is written in the Neviim; and in the book is the Megillah. Esther's book was the third, not a fourth, and her request was granted. The Megillah itself records that Esther's decree confirmed the days of Purim and was written in a book.

Esther knew that a salvation which is not remembered is easily lost. Think of a time Hashem helped you or your family in a way you could not have arranged yourself: a recovery, a rescue, a door that opened at the last moment. This week, write it down in a few honest paragraphs and put it where your family will find it, or tell it at the Shabbos table. If it fits, choose a small way to mark the day each year, such as a seudah of thanks or extra tzedakah, so that your children's children will know.
