Parshas Chayei Sarah

[Ayala1]

Rabbi Reichman spoke about how when Avraham mourned Sarah, he mourned not only his personal loss, but also (and mainly) the greater loss of the world at the passing of such a tzadeikess.
It's amazing that Avraham was able to put aside his personal feelings at such a hard time.
It's also interesting that after Sarah died the torch was passed on to Yitzchak and Rivka, as symbolized by Rivka's tent having all the same elements as Sarah's tent. I think this could be understood as the important elements that Sarah brought to the world were not lost at her passing, but were still in the world. However, the unique way that Sarah acted would not be replicated, but Rivka did continue in some way the important work that Sarah started.
When we continue to follow in Sarah's ways we are continueing her mission, and she is not ever truely lost.
