It’s the period of Shovavim. Here’s some links on the whys and wherefores of Shovavim.
Shovavim is an acronym for the parshiyot that we read during the period between Chanukah and Purim. Rav Nachman Cohen writes that this period is an auspicious time to repent for Adam’s sin with the Eitz Hadaat and his subsequent errant behavior, pegimat habrit, for which mankind suffers until today. Why do we specifically repent now for the sin of Adam?
This period falls after the winter solstice when the days begin to get longer. When Adam sinned, the days began to get shorter and he thought it was because of his sin. When the days began to get longer again, he realized he was not doomed and that his repentance had been accepted. Thus this period is an eit ratzon where one can connect to Hashem.
Working on curbing one’s physical desires and avoiding inappropriate pleasures seems male focused. What is the corollary for women? The Maharal says that the primary praise of a woman is her level of tzniut. Rav Pincus writes that because Adam and Chava did not conduct themselves modestly, the snake desired Chava and devised a plot to make her sin. Therefore, in a sense, the sin of Eitz Hadaat came about through immodesty.
What is modesty? It is a call to concentrate our energies on our inner personality, our spiritual nature, which is deep and hidden within us. We must become attuned to our souls instead of getting caught up in the outer trappings of the physical world. Shovavim is not only a time to work on tzniut but a time of introspection, a time to work on our relationship with Hashem. This entails watching our behavior with the awareness that we are in the presence of Hashem. It is irrelevant what other people think. Life is about walking alone with Hashem. Elevating mitzvot to a higher level by practicing modesty in deed – not talking about the mitzvot you’ve done, is an appropriate goal to work on during Shovavim.
There are a number of reasons given for this period of Teshuvah:
1) During this period we read the parshiyot which describe the Jews’ suffering and exile in Egypt and their redemption, salvation, and exodus by the Hand of God. Just as Israel in the Torah called out from their physical exile, so too we call out of our personal spiritual exile. Just as the Jewish people overcame the darkness of the Egyptian exile so too we try to overcome the spiritual darkness in our lives and come closer to God from whom we are separated.
2) Many Chassidic and Kabbalistic sources describe the focus of this period as strengthening our resolve in areas of family purity (Taharat Hamishpacha) and in studying and keeping the laws of family purity.
Shovavim is something that came from the Mekubalim. I once heard it explained that as the generations get weaker, Hashem reveals to us the hidden light that can be found deeper into the year. Let’s face it, we didn’t really do a great job on Aseres Yimei Tshuva and Hashem is showing us these loopholes and extensions because he yearns for us to return and wants us to take advantage. This ties in nicely with something I heard from the Chofetz Chaim who when asked skeptically about Yom Kippur Katan, said that we no longer can go a whole year without a Yom Kippur. We need one once a month.
