I was boarding an airplane recently when the man in front of me, who looked to be about 20 years my senior, turned and asked, “How long have you worn a kippah?” He was not wearing a kippah, so I was a little startled by this very direct question. But my mind picked up on other cues and quickly filled in a story that he was Jewish and was asking this question out of a sense of solidarity.

As I’m regularly privileged to do, I spent part of this first week of February with 50 rabbis and cantors, some of the 530 alumni of our IJS clergy cohort programs, during our annual Hevraya retreat in Simi Valley, California. First and foremost: We were all okay with the weather. Thankfully, the American Jewish University’s Brandeis-Bardin Campus, where we have long held this retreat, is at a high enough elevation to avoid major flooding. While there were some travel delays, everyone arrived safely. And given all that these spiritual leaders have been holding for themselves and their communities in recent months, it didn’t take long for the weather to become an afterthought.

During this retreat, I found myself reflecting on a talk I listened to recently by one of my favorite teachers, Gil Fronsdal, about the meaning of “retreat.” Gil suggested that the word is a bit of a misnomer, because the label “retreat” suggests that the experience is a pulling back from what’s normal: Our normal world is full of hustle and bustle, but on retreat we do something different, live at a slower rhythm, engage more deeply with ourselves and the world. And while that’s true, Gil suggested that a better label might be “return”–because the truth is that our actual normal is that slower, deeper reality. It’s the fast-paced, surface-level life before and after the “retreat” that we should see as the unusual setting. When we go on retreat, we’re really returning to our truest nature.

The rabbi in me was immediately drawn to this notion of return as teshuva. Every year during Elul and Tishrei, we make a special effort to return, as it were, to our factory settings: to reconnect with what we know to be our deeper nature, the go back to the intentions we know we really have. Throughout that intense period of teshuva, it can feel like we’re on a kind of retreat, and at the end of it we’re remade and reborn.

Yet we don’t have to wait for Tishrei, as evidenced by the retreat/return we held for those spiritual leaders this week. For so many of them, this time has become a sacred period of reconnection, renewal, and rebirth. It’s truly one of my greatest honors and joys that these holy souls trust us to create and hold the container for them to do that returning.

At morning services on Tuesday, Rabbi Hannah Dresner, one of our wonderful alumni, shared a beautiful teaching about Parashat Mishpatim from the Hasidic master Rabbi Yehudah Leib Alter of Ger’s Sefat Emet (Terumah, 1895). At the end of the Torah portion, Moses ascends into the mountain, where he will stay for 40 days and 40 nights while he receives the Torah. The Sefat Emet picks up on the number of 40 days, which in the mind of the Talmudic sages is the same amount of time it takes after conception for a fetus to be formed in the womb. Putting the two ideas together, he teaches that during his sojourn on the mountain (which was enveloped in cloud, suggesting to the midrashic imagination a womb-like experience), Moses “received an entirely new form”–that is, he was literally transformed, renewed, reborn. And further, through the study of Torah, all of us have a share in Moses’s experience–we can experience our own renewal and transformation too.

I wonder if we might understand this transformation and renewal as of a piece with the return we experience on retreat or during the fall holidays. I wonder if we might think of it as available to us not only through those intensive experiences but even on a weekly basis (Shabbat) and a daily or even moment to moment basis through our mindful return to our intention. As we say in our liturgy, the Divine “renews creation each day.” Likewise, we can, through our practices, experience that renewal, that return to our factory settings, in every time and place.

In some of my recent morning meditation sits, I’ve noticed a feeling of sadness and grief arising. Yes, of course, there’s plenty of cause for sadness and grief in the world and amongst the Jewish people. But this grieving was coming up from a different place. It’s some anticipatory grieving around a subtle but significant shift in the life stage my wife and I are going through as our middle child prepares to graduate high school and leave home.

In one of those mysterious poetic rhymes in which life can sometimes speak, my children–21, 18, and 11–have almost precisely the same spread in age as my brothers and I (I’m the youngest). And I’m finding echoes of the feelings of loss that I experienced when my two older brothers had flown the coop and it was down to just my parents and me at home. But this time, I’m approaching that point as one of the parents, aware of all the memories of these now-grown children in this house we’ve lived in for the majority of their lives. While I am happy that both my older boys are making their way in the world–and that we can still look forward to the company of our wonderful little one for a few more years–I get why there’s some grief making its presence felt. The shape of home is shifting, and that’s hard.

Home, its shape-shifting, and even the undertow of the powerful emotions surrounding it, is a theme in Parashat Yitro–though I think we sometimes have to look for it a little. But when we do, it’s right there beneath the surface. Look right at the beginning: “So Jethro, Moses’ father-in-law, took Zipporah, Moses’ wife, after she had been sent home, and her two sons—of whom one was named Gershom, that is to say, ‘I have been a stranger in a foreign land’; and the other was named Eliezer, meaning, ‘The God of my father was my help, delivering me from the sword of Pharaoh.’ Jethro, Moses’ father-in-law, brought Moses’ sons and wife to him in the wilderness, where he was encamped at the mountain of God.” (Ex. 18:3-5) Rashi, quoting the midrash, paints a scene wherein Aaron, when he first greets Moses on his way back to Egypt from the burning bush, asks him, rhetorically, “We’re already grieving so many people in Egypt; why add to the number?” So Moses sends his wife and children away–a moment, one imagines, of painful family separation, of grieving and loss, of shifting the dimensions and feelings of home.

Home is also present in the Ten Commandments: the mitzvot of honoring parents (#5), honoring marriage (#7), focusing our attention on what is present in our homes and not coveting that which is over the fence (#10)–and the ways we can imagine or have experienced the transgression of those commandments–all of these tap into the strong emotional currents surrounding the nature and shape of home.

I’m fond of saying that I think spirituality is our capacity to feel truly at home in the universe. And in this sense, perhaps the most powerful teaching about home comes not in any of these moments that I’ve mentioned, but in the mitzvah of Shabbat: “For in six days YHVH made heaven and earth and sea—and all that is in them—and then rested on the seventh day; therefore YHVH blessed the sabbath day and hallowed it.” Like the Creator, for six days we label and separate, calling things heaven or earth or sea, this name or that home, home or not-home. All that naming connotes both standing in relationship with and standing over and against the world–at home in the world, but also not fully at home in it at the same time. On Shabbat we rest from all that, from the constant work of naming and labeling and separating. We allow ourselves to feel deeply, truly at home–in the world, in our houses, in our relationships, in ourselves.

Yet Shabbat doesn’t only happen every seven days. Shabbat consciousness is actually available to us every seven hours, every seven minutes, every seven seconds. That, in many ways, is the whole point of Jewish spiritual practice. When we can cultivate it and allow it to take root and grow within us, we can respond to the shifting shapes and tones of home more wisely and graciously–because we can sense that, on the deepest levels, we’ve never really left home at all.
