Do you remember, with crystal clarity, a class that you attended thirty years ago? I remember one such class like it happened yesterday—both what was said in the class, and how it made me feel.

It was a class attended by rabbinical and cantorial students, and Jewish educators and federation workers. The class was taught by Rabbi Elka Abrahamson, who was at the time a congregational rabbi in Minnesota. Elka has since gone on to head the Wexner Foundation. The class was August, 1995, in Cape Cod. The topic at first felt like a double disconnect. She was talking about Sukkot, two months before Sukkot. And she was talking about a word, a concept, a ritual, I had never heard of before: Ushpizin.

The word Ushpizin is Aramaic for guest. It refers to a mystical Sukkot tradition that comes from the Zohar in which people invite seven biblical figures to our Sukkah. The tradition has, I would say, a little bit of a patriarchal feel. The seven invited guests traditionally are: Abraham, Isaac, Jacob, Moses, Aaron, Joseph and David. Over time a female roster of Ushpizin was also developed inviting Sarah, Rebeca, Rachel, Leah, Miriam, Deborah and Esther into our Sukkah. The classic idea would be to connect with the spiritual legacy of each of these biblical figures.

Now, at Cape Cod, Rabbi Abrahamson did a modern move on this classic mystical tradition. The students were seated in a circle. She added an empty seat in the circle and invited us to welcome into our August sukkah somebody who is not here, either because they passed away, or for any other reason we fell out of touch with them. Each person would go over to the empty chair and introduce a loved one whom we no longer see. It was all very emotional. People carry stories. People carry scars. And this exercise of introducing someone who can no longer be at our Sukkah but whom we would like to invite to our Sukkah brought out a lot of vulnerability in ways that made everyone around the circle listen in rapt attention.
