Tomorrow night is the 7th day of Sukot. It’s called Hoshana Raba. Kind of like a mini-Yom Kipur. During services, we destroy the willow branches that are part of the Lulav and Etrog (see the picture below) we’ve employed during this holiday. We either do this because it was part of the rain bringing rituals that existed centuries ago- or to remind us of repentance. (The origin of the practice is simply not clear to us today.)
