Hashem gave us the festival of Sukkot right after Yom Kippur. The most intense spiritual time of the year, spent fasting and praying like angels, is followed by the most physical. Sukkot involves the acquisition building materials, construction, and focus on the harvest.
Our first hint of Sukkot is at the end of the Book of Jonah, read during Yom Kippur. Jonah builds a sukkah to protect himself from the hot sun and wind. In Nineveh, he wanted to seal himself off from the non-Torah environment around him. But this is the man that also tried to get away from God, and here he is again, selecting what things to accept from God: Rejecting the sun and wind but welcoming the plant that grows overhead.
Living in the sukkah, we are shielded from distractions that would take us away from any clarity we were blessed with on Yom Kippur. There is no TV, no computer or stereo. This is especially so for a yeshiva student; the break has started, and there could be many temptations outside yeshiva. Might as well be inside the sukkah, learning Torah, giving over our concern and appreciation for each other, and indulging in the wholesome foods and pleasant breezes of God's creation.
But at the same time, we are in God's world. "I recall the devotion of your youth, when you followed me into an unsown land." When Am Yisrael came out of Egypt, they were crowned with Clouds of Glory. They hovered above, gathering us together, as a sign of Hashem's love for us like a proud father after we showed our loyalty to Him and our care for each other. They protected us from the harsh environment and, as a tangible reminder of the Divine Presence, they kept our hearts focused on the One Above. We counted on Him for our every need, and accepted every circumstance and worldly involvement he placed before us.
That is one of the concepts represented by the sukkah; sealed with other Jews inside a Spartan chamber of mitzvot surrounded by Jewish symbolic decorations, but at the same time the space is barely distinct from its environment, seeing the stars above and feeling the cool night air, with guests streaming in and out.
It is the unfolding of a process begun before Rosh Hashanah. Whereas Nissan is the new year for the Jewish people, Tishrei is the new year for all of creation. It tells us the two are interdependent. The Jewish people need a functioning world in order to have an ultimate purpose, and the world needs a functioning Jewish people in order to have guidance toward that purpose.
And this is the kavanah the Torah wants us to develop--consciousness of both prat and klal, specific and general. We focus on mitzvot and Torah but, at the same time, open our hearts and minds to whatever God is giving us at any moment.
We should be blessed to, like Jonah, come to understand the full power and meaning of what it is to be a Jew in this world. Then will be fulfilled the prophecy that "every Jew will have ten people on his coat-tail, pleading, 'teach us of the ways of your God.'"
