In a physical, historical, and spiritual way, Hanukkah is the Festival of Lights.
It is hard to appreciate light without darkness, so today we celebrated light (ohr) and darkness (chosech).
I blacked out our windows before the students arrived, and set up our 'brightest' activities.
Did I mention I loved it? From a sensory point of view, the experience was phenomenal. The change in sensory input was marked and caused for more relaxed environment.
We had a lovely discussion about what we value in light and in darkness.
