Rosh Chodesh Kislev

The Sages taught in a baraita: It is a mitzva to place the Hanukkah lamp at the entrance to one’s house on the outside, so that all can see it. If he lived upstairs, he places it at the window adjacent to the public domain. And in a time of danger, when the gentiles issued decrees to prohibit kindling lights, he places it on the table and that is sufficient to fulfill his obligation. Rava said: One must kindle another light in addition to the Hanukkah lights in order to use its light, as it is prohibited to use the light of the Hanukkah lights. And if there is a bonfire, he need not light an additional light, as he can use the light of the bonfire. However, if he is an important person, who is unaccustomed to using the light of a bonfire, even though there is a bonfire, he must kindle another light. The Gemara asks: What is Hanukkah, and why are lights kindled on Hanukkah? The Gemara answers: The Sages taught in Megillat Ta’anit: On the twenty-fifth of Kislev, the days of Hanukkah are eight. One may not eulogize on them and one may not fast on them. What is the reason? When the Greeks entered the Sanctuary they defiled all the oils that were in the Sanctuary by touching them. And when the Hasmonean monarchy overcame them and emerged victorious over them, they searched and found only one cruse of oil that was placed with the seal of the High Priest, undisturbed by the Greeks. And there was sufficient oil there to light the candelabrum for only one day. A miracle occurred and they lit the candelabrum from it eight days. The next year the Sages instituted those days and made them holidays with recitation of hallel and special thanksgiving in prayer and blessings.

Because of this, the sages of that generation ruled that the eight days beginning with the twenty-fifth of Kislev should be observed as days of rejoicing and praising the Lord. Lamps are lit in the evening over the doors of the homes, on each of the eight nights, so as to display the miracle. These days are called Hanukkah, when it is forbidden to lament or to fast, just as it is on the days of Purim. Lighting the lamps during the eight days of Hanukkah is a religious duty imposed by the sages, like the reading of the Megillah on Purim.

Whoever is obligated to read the Megillah is also obligated to kindle the Chanukah lamp. On the first night, a person lighting [the lamp] recites three blessings. They are:
Blessed are You, God, our Lord, King of the universe, who has sanctified us with His commandments and has commanded us to light the Chanukah lamp.
"...who wrought miracles for our ancestors...."
"...who has granted us life, sustained us...."
When a person who did not recite a blessing [on his own Chanukah lamp] sees a lamp, he should recite the latter two blessings. On subsequent nights, a person who kindles the lamp should recite two blessings and one who sees a lamp should recite one, for the blessing Shehecheyanu is recited only on the first night.

Ulla said: There were two amora’im in the West, Eretz Yisrael, who disagreed with regard to this dispute, Rabbi Yosei bar Avin and Rabbi Yosei bar Zevida. One said that the reason for Beit Shammai’s opinion is that the number of lights corresponds to the incoming days, i.e., the future. On the first day, eight days remain in Hanukkah, one kindles eight lights, and on the second day seven days remain, one kindles seven, etc. The reason for Beit Hillel’s opinion is that the number of lights corresponds to the outgoing days. Each day, the number of lights corresponds to the number of the days of Hanukkah that were already observed. And one said that the reason for Beit Shammai’s opinion is that the number of lights corresponds to the bulls of the festival of Sukkot: Thirteen were sacrificed on the first day and each succeeding day one fewer was sacrificed (Numbers 29:12–31). The reason for Beit Hillel’s opinion is that the number of lights is based on the principle: One elevates to a higher level in matters of sanctity and one does not downgrade. Therefore, if the objective is to have the number of lights correspond to the number of days, there is no alternative to increasing their number with the passing of each day.

Chanukah is an aspect of the Holy Temple. The primary concept of the Temple is the revolving wheel. The Temple represented “the superior below and the inferior above” (Pesachim 50a; Bava Batra 10b). God lowered His presence into the Temple – this is “the superior below.” The form of the Temple was engraved on high – corresponding to “the inferior above.” The Temple is therefore like a dreidel, a rotating wheel, where everything revolves and is transformed.

This is why we play with a dreidel on Chanukah.

For the world is like a rotating wheel. It spins like a dreidel, with all things emanating from one root.
