As we are in the days of Hanukkah, it is appropriate to mention some teachings regarding this unique holiday. First, it is important to consider that, beyond the story of Hanukkah itself, of the sacrifice of the Kohanim (priests) of that time to defend the values of Judaism, there are teachings that our sages hinted at in the various passages in the Torah where the themes of this holiday are discussed.
An example of this is a halakha (Jewish law) concerning the laws of Hanukkah. The Talmud states (Shabbat 21b, cited in Shulchan Aruch Orach Chaim 672:1): "[The time for lighting the Hanukkah candles is] from sunset until there are no people in the streets," because if there are no people in the streets, no one will be able to see the Menorah to remember the miracle that occurred to the Jewish people in those days.
Now, this seems like a simple law, but, as we shall see, there is an incredible lesson hidden in the words of our sages. In the original Hebrew, the text says ad sheTijle reguel min haShuk (until the legs of the marketplace run out (lit.)).
To understand the teaching, we must analyze each word separately and then put them back together.
ad: until.
sheTijle: means "let it end", but can be understood as "let it yearn" and "let it desire".
Reguel means "leg," but in this new context, we will understand it as the lowest level of the Jewish people. The entire Jewish people are like a body with different limbs, and each soul corresponds to a particular limb, such as the right arm or the left leg. Naturally, the foot is the lowest limb, so Reguel symbolizes the Jew disconnected, so to speak, from Judaism, the one who does not participate in a community, the one who does not even identify with his Judaism.
min: del.
HaShuk: literally means the marketplace, but here it symbolizes that which lies outside the realm of the Torah. Just as all kinds of goods can be found in the marketplace, in the same way, whoever is outside the context of holiness and purity that the Torah offers is under constant danger of being influenced by negative things contrary to Judaism.
Putting our halakha together again, we see that our sages are giving us a very profound message about Hanukkah: Until what time should the Hanukkah candles be lit? Or, to put it another way, until when should I shine a light, illuminate another person's life? Until that person, who is at a low level of connection with God (reguel), yearns (sheTichle) to rise from their worldliness (haShuk) and reintegrate into Judaism.
