This is an image of the first holy letter - Alef. When taken apart, the Alef can be seen as a vav (6th letter) in the center, with a yud (10th letter) above and below. The yud above is the soul, the yud below is the body, and the vav between is the 6 middot in harmony, which is Torah. There is also a reference to Chanukah, because the light of Torah expels darkness, like the Chanukah candles.
