The main floor is a meeting room with seating for up to 400; the second and third levels ring the space and include galleries and informal meeting places for students. Two-hundred eighty-eight restored stained glass windows bathe the interior in colored light. Atop the dome a quotation in colored slate from Rabbi Tarfon, found in the Talmud's Pirkei Avot, proclaims in Hebrew: "The day is short, the work is great, the reward is much, the Master is urgent."
