Let us look for historical cycles based on the life of our nation’s founder, Avraham. When Avraham was 70 years old, Hashem informed him that his descendants would go down to Egypt for 400 years and that they would be redeemed from there, amassing great riches. (There was apparently a dispute between Ephrayim’s and Levi’s descendants as to how to calculate this time period. See the Ramban on Bereishit 15:13 and the Rishonim on Shemot 12:40. Rashi says that is counted from the time of Yitzchak’s birth until the Exodus.)
According to this timeline, there were approximately 480 years from when Avraham recognized his Maker until Bnei Yisrael’s emergence as a free nation. The same number of years passed from the Exodus until the building of the First Temple in Jerusalem (Melachim I, 6:1). 480 is an interesting number, as it is the product of 40 and 12. Throughout Tanach, 40 years is considered a generation (Tehillim 95:10) and an era (see Shoftim 3:1; ibid. 5:31; Shmuel I, 4:18 and more). Certainly, the number 12 is significant in Jewish history, as this is the number of tribes that formed our nation.
Reviewing Jewish history, we see that this time interval is a very significant one; it carves out historical periods. 480 years after the building of the First Temple, the second one was built (the first stood for 410 years and for 70 years there was no Temple - see Arachin 12b and Yirmiyah 29:10). Another 480 years later marks the rebellion of Bar Kochva, upon the heels of whose defeat the settlement of the Second Commonwealth faded away. After an equal amount of time, we come to the end of the Talmudic period and the beginning of that of the Geonim. Another 480 years later, the Rif and Rabbeinu Gershom lived, ushering in the period of the Rishonim in Spain and Germany, respectively. This period also lasted some 480 years until the time of Rav Yosef Karo and Rav Moshe Isserles, who authored the Shulchan Aruch and its glosses, respectively; thus began the period of the Acharonim. This period, where Jewish scholarship and life was centered in and around Europe, came to an end some 480 years later with the Holocaust.
Finally, in the aftermath of the Holocaust, the Jewish people were able to launch a new enterprise in an old/new location: the establishment of the State of Israel in the Land of Israel. Let us pray that we will appreciate the great responsibility our generation bears to help turn this development of atachalta d’geula (the beginning of redemption) into a full redemption.

Shlach Lecha "Why So Many Don't Make Aliya?" - Parshat Shlach
This short article deals with the weird phenomena that every single time Am Yisrael is meant to enter the Land of Israel, throughout the Tanach, 2nd Temple and until today, they "chicken out" and look for excuses.

Kuzari -Rabbi Ari Shvat Kuzari class 4
The class deals with Islam and how the Muslim tries convincing the King of the Khazars, and why he was also rejected.

Beha'alotcha JEWISH STATE= GUIDE TO G-DLINESS & SELFLESSNESS
A Jewish State not only is a good idea, but educates us towards selflessness, altruism and G-dliness in our daily lives.

Ein Aya In Zion Even the Smoke of the Bark is Sweet
Just as Jewish nationalism is different from others, so too our capitol of Jerusalem is totally different than other national capitols. Rav Kook beautifully explains the passage in the Talmud that the trees of Yerushalayim were cinnamon trees.

Kuzari -Rabbi Ari Shvat Kuzari class 3
The second speaker invited to convince the Khazar King is the Christian, who presents their beliefs. Even before the questions of the King, "between the lines", the author R. Yehuda HaLevi already begins disproving them.

Ein Aya "Intimacy: Love, Life & Giving or Egocentric Taking & Expiration"
Today, many confuse between intimacy in marriage, based on love, giving and life which are diametrically opposed to empty "sex", pornography and prostitution which destroyed the Beit HaMikdash. The practical importance of clarifying this topic in today's western society is obvious, especially for young adults.

Kuzari -Rabbi Ari Shvat Kuzari class 2
The King of the Kazars, in his search for truth, starts by inviting the philosopher. This is a "crash-course" on Aristotelian philosophy and the reasons why the king is not convinced. Through this dialogue, R. Yehuda HaLevi already foreshadows some of his central ideas that will appear later.

Shavuot "Love of Torah = Love of Israel"- for Shavuot
People often identify Judaism as just a religion, but upon examination, we see, even halachically and explicitly in the siddur, that the Torah is dependent upon Am Yisrael, Jewish nationalism.

Ein Aya The Middle-Child & Anti-Tzni'ut Syndrome- Negative Attention
Although tzni'ut is for men just like women, Rav Kook deals here with the sources in Yishayahu and the Talmud which deals with the special problem of lack of tzni'ut in women's dress and actions, where it's not just a problem of midot and character traits, but also can include practical, social and national ramifications, as well, which caused the destruction of the Beit HaMikdash and exile from Israel. The class continues the previous one (Ayn Aya Shabbat vi, 29), and is a must for all educators and parents of high-school aged and young adults.
