It is written that the 7 shepherds come to visit us in the Sukkah, each one leading the group of shephards into the Sukkah, night after night, for the seven nights of Sukkot.
The 7 shephards:
how does that work? Their souls travel through the Sukkah, like a portal between worlds.
The waving of the Lulav & Etrog is like the key that opens the door to the other side.
This year, Sukkot, aligns with what is called a supermoon, and blood moon, so the night sky wil be especially spectacular. A full moon is typical for Sukkot since it falls on the middle of the month of Tishrei.
