That this light is not like visible light, but rather, the light of knowledge. Again, I do not think this idea is restricted to Jewish Mysticism. The idea is that, before the sun, there was a time of 'enlightenment' where knowledge was abounding.

Oh! This comes up in Foucault's Pendulum by Umberto Eco.
