Engineering Light

Windows are designed to be narrow on the outside and wide on the inside, to spread their light to a larger space. The windows in the Temple, however, were fitted the other way around, representing the fact that the function of the Temple’s windows were for precisely the opposite purpose. While regular windows are meant to bring light into a structure, the Temple’s windows were to bring light outside of them; sharing the light of Judaism with the rest of the world.

We find a similar idea in Maimonides drawing of the Menorah, symbolizing the import of taking the light of the Menorah, the light of the Torah, and sharing it with the rest of the world.
