The Sukkah Mobile
For forty years, as our ancestors traversed the Sinai Desert prior to their entry into the Holy Land, miraculous "clouds of glory" surrounded and hovered over them, shielding them from the dangers and discomforts of the desert. Ever since, we rememberG‑d's kindness and reaffirm our trust in His providence by dwlling in a Sukkah – a hut of temporary construction with a roof-covering of branches – for the duration of the autumn Sukkot festival. For seven days and nights, we eat all our meals in thesukkah – reciting a special blessing – and otherwise regard it as our home. We reaffirm our trust in His providence by dwelling in a sukkah
The Sukkah Mobile is about bringing this wonderful Mitzvot to the streets -- A Mitzvah on the spot for people on the go. To some degree, the Sukkah Mobile, best resembels the traveling clouds of glory.
Another mitzvah that is unique to Sukkot is thetaking the Four Kinds: an etrog (citron), a lulav (palm frond), at least three hadassim (myrtle branches) and two aravot (willow branches). The Midrash tells us that the Four Kinds represent the various types and personalities that comprise the community of Israel, whose intrinsic unity we emphasize on Sukkot.
On each day of the festival (except Shabbat), during the daytime hours, we take the Four Kinds, recite a blessing over them, bring them together in our hands and wave them in all six directions: right, left, forward, up, down and to the rear. (The Four Kinds are also an integral part of the holiday's daily morning service.)
