What two halachically significant factors are gleaned from the wording of the Alter Rebbe in explaining the purpose and function of the Clouds of Glory and the Mitzvah of Sukkah? Why do we specifically commemorate the miracle of the Clouds of Glory and not the Manna or the Well of Miriam? How does the obligation of Kavana/intent differ in the Mitzvah of Sukkah vs. other Mitzvos? Why isn’t Sukkos directly after Pesach? When should the Sukkah be built?
