Maybe it's not just the challah talking. Jewish tradition whispers of a secret gift bestowed upon us every Shabbat: a second soul.

Imagine it: As Shabbat descends, as the candles are lit and the aroma of the festive meal fills the air, something truly remarkable happens. According to the mystics, every single Jewish person receives an additional soul. A neshama yetera, an extra soul, descends. The Zohar, that foundational text of Jewish mysticism, tells us that all the souls of Israel are crowned on the eve of Shabbat.

This isn't just any soul. It's a celestial soul, a holy spirit overflowing with blessing, with song, and with a joy drawn directly from the heavens. It's a spark of the divine, a taste of the World to Come.

What does this extra soul do? Well, for one thing, it sharpens our minds. With this spirit present, our power of understanding is greatly increased, as we are told in Tree of Souls (Howard Schwartz). We're more receptive to the beauty around us, more attuned to the spiritual currents that flow through the universe.

And where does this wondrous gift come from? Some say these extra souls bloom forth from the Etz Chayim, the Tree of Life, that central symbol of mystical vitality. Others believe they are the offspring of the Shekhinah, the divine feminine presence. The Shekhinah, in this understanding, descends and spreads Her wings over Israel, forming a canopy of peace. It's like She's watching over us, sheltering us as a mother bird does her fledglings. And as She hovers, wings outstretched, She brings forth these new souls for each and every one of us.

According to Ginzberg's retelling in Legends of the Jews, this spirit bathes in the spices of the Garden of Eden as it descends. Imagine that aroma! It then settles upon the holy people of Israel. With the arrival of this Shabbat-soul, all sadness and anger disappear, and joy reigns both above and below. All during the Shabbat day, this extra spirit dwells within, enchanting our very being.

But here’s the bittersweet part. Like all beautiful things, it’s temporary. On Saturday night, as three stars appear in the sky, marking the end of Shabbat, the neshama yetera flies forth and returns to its place on high. We feel a little… emptier. A little less connected.

So, what are we left with? Perhaps a longing for that heightened state of awareness. A memory of the peace and joy that filled our hearts. And, hopefully, a renewed appreciation for the gift of Shabbat, and the promise that it will return, week after week, bringing with it that precious, fleeting glimpse of the divine. As we find in Midrash Rabbah, the very name of this soul is "Shabbat," because Shabbat rest and peace are a foretaste of the World to Come.

Maybe the question isn’t just about where the soul goes when Shabbat ends, but what it leaves behind within us. A seed of holiness, a spark of understanding, a deeper connection to the divine that lingers long after the stars appear.
