Chanukah begins on the 25th day of the Hebrew month of Kislev and continues for eight days. Because its date depends on the lunar rather than the solar calendar, in some years, Chanukah overlaps with Thanksgiving while on others it coincides with Christmas. This year, the fifth day of Chanukah lines up with the anniversary of the 1941 attack on Pearl Harbor.
In a special prayer we say each day of Chanukah we thank God for handing victory to a small, dedicated group who went to battle against the mightiest empire of the day. As part of that battle, they also faced internal opposition from the Hellenists, who were Jews who succumbed to the appeal of Greek culture. These Hellenistic Jews wanted their faithful brethren also to abandon God.
An unusual rule surrounds the lights of Chanukah that are kindled each of the eight nights of the holiday. Before you can light the flames, there must already be light in the room. The Chanukah lights cannot be used for utilitarian purposes. The menorah beckons us to have vision, not to limit ourselves to what is within our sight. Before we can tap into the miracle of oil that burned beyond its physical ability, we have to prepare the room.
