Hopefully, we go into Sukkos on the back of an uplifting Rosh Hashana and Yom Kippur. Resolved to do better and be better, we feel invigorated and full of life. Yet we leave Shul and go right back into the daily grind of everyday living, with the same habits and routines of yesterday.

What sort of change can we expect if we go right back to what we were doing?

Perhaps the mitzvah of Sukka can teach us.

The defining feature of the Sukka is that the roof has to be made from unprocessed raw plant matter and must create sufficient shade. The classic example is the waste product from the threshing floor and winery once you’ve extracted the useful resources. Instead of disposing of the refuse, the husks and stalks can be recycled and repurposed for the mitzvah – which is precisely what Teshuvah is.

It’s not accurate to say that we put the past wholly behind us and move on. Instead, we should carry the past forward with us. Past mistakes can become informative stepping stones for us to learn and improve. History need not repeat itself, and we can evolve.

The Esrog echoes this concept as well. It is the choicest of the four species and the metaphor for an ideal human, yet if you cut one open, the edible fruit is surpassingly small – the inedible rind makes up most of the mass. Even the ideal person has built up plenty of rind over time, yet it’s still a beautiful Esrog.

An old Chassidic saying highlights Sukka as the only mitzvah where a person enters with his muddy boots. Muddy boots are th mark of our journey through life, intimately interconnected with who we are and entirely inseparable; they are welcome in the Sukka.

This may also explain why the Zohar calls the Sukka the shade of God – God is with us in our dark moments too – צילא דמהימנותא. It may also explain why of all festivals, Sukkos, in particular, is the time of joy – the debits can turn into credits – זְמַן שִׂמְחָתֵנוּ.

There is a tangible Kabbalistic dimension here as well. The Hebrew word for husks and rind is קְלִפָּה. In Kabbalistic symbolism, souls are shining lights, and sins cloak the soul in layers of קְלִפָּה, sort of like an onion. Instead of discarding the קְלִפָּה, Teshuvah transforms it from a bad thing into a good thing.

It’s not a magic trick – sins and transgressions are treated differently based on Teshuvah’s motivation. The way you adapt your past mistakes materially affects the way you incorporate the lessons learned to be a better person.

So perhaps that’s why Sukkos comes right on the back of Rosh Hashana and Yom Kippur. While we shouldn’t just sink back into the same routine as before, Teshuvah doesn’t need to look like such a radical departure from the past. Change is incremental – it isn’t so different from past habits and routines, maybe it’s quite similar, but with small improvements and modifications.

Sukkos teaches the holistic view of how we change.

We all make mistakes, but the only real mistake is the one we don’t learn from.
