Ezra, head of the Sanhedrin and the leader of the Jewish people at the time of the building of the Second Temple, made an historic address to a three-day assemblage of Jews in Jerusalem, exhorting them to adhere to the teachings of the Torah and to dissolve their interfaith marriages (the Jewish people were on the verge of complete assimilation at the time, following their 70-year exile in Babylonia).

The Rosh Hashanah ("new year") of Chassidism, marking the liberation of Rabbi Schneur Zalman of Liadi and the subsequent blossoming of Chabad Chassidism, is celebrated for two days, Kislev 19-20. (The Rebbe was released from prison on the 19th, but his full freedom was only obtained late in the evening -- Kislev 20 on the Jewish Calendar.) The two days are celebrated with farbrengens (Chassidic gatherings) and an increased commitment to the ways and teachings of Chassidism. Tachnun (supplication) and similar prayers are omitted. For more information and links, see entries for yesterday Kislev 19.
When the Creator came to create the human being, Truth said, "Do not create him, for he is full of lies.
Kindness said, "Create him, for he will do acts of kindness."
What did the Creator do? He cast Truth earthward, and created the human being.
That is why it says, "Truth will sprout from the earth."
—Midrash Rabba
Every argument in Torah can be reduced to the same crucial question:
Do we follow rigid, immutable truth, regardless? Or do we take into account the particulars of this situation? Do we look only from above-down, or do we take the view from below as well?
The debate is never easy, because truth is no longer truth once compromised. Rather, we need to find a way to hold both ends of the stick at once.
That is why the debate must occur among us human beings here on earth, and from there the resolution must sprout. For only in that way will Truth come down to earth, where it truly belongs.
