Sukkot is a holiday of thanksgiving!
From the Torah , we sit in the sukkah in order to retain a historical link with our ancestors and to remember all what God did for us when we left Egypt.
None of the holidays are as rich in mitzvot as is the Holiday of Sukkot. We build a sukkah, we shake the four species; and most of all, we observe the specific commandment to be happy – rejoice!
The word “sukkot” means “booths”, and refers to the temporary dwellings that we are commanded to live in during this holiday.
“A house becomes a home when we eat together in it and, similarly, eating together in a Sukkah is how we fulfill the mitzvah “to dwell in the Sukkah”…
Maimonides, in his Guide to the Perplexed says that sitting in the Sukkah teaches us “to remember our evil days in ours day of prosperity.” We thank God repeatedly and to do so by leading a modest and humble life. Thus, according to Maimonides, the Sukkah is meant to induce both a feeling of gratitude and a feeling of humility.
