Happy Sukkot

Via the Chabad:

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 remember G-d's kindness and reaffirm our trust in His providence by dwelling in a sukkah--a hut of temporary construction with a roof covering of branches--for the duration of the Sukkot festival (Tishrei 15-21). For seven days and nights, we eat all our meals in the sukkah and otherwise regard it as our home.

Another Sukkot observance is the taking of the Four Kinds: an etrog (citron), a lulav (palm frond), three hadassim (myrtle twigs) and two aravot (willow twigs). On each day of the festival (excepting Shabbat), 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, backward, up and down. 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.

Sukkot is also called The Time of Our Joy; indeed, a special joy pervades the festival. Nightly Water-Drawing Celebrations, reminiscent of the evening-to-dawn festivities held in the Holy Temple in preparation for the drawing of water for use in the festival service, fill the synagogues and streets with song, music and dance until the wee hours of the morning.

The seventh day of Sukkot is called Hoshaana Rabbah ("Great Salvation") and closes the period of Divine judgment begun on Rosh Hashanah. A special observance is the Aravah--a bundle of willow branches that are carried around the synagogue.

Sukkot starts this Friday at sundown.
