96. Anyone may discern that spiritual light is altogether different from natural light if he attends to his mind's thoughts. For when the mind thinks, it sees the objects of its thought in light, and people who think spiritually see truths, and this just as well in the middle of the night as during the day. Therefore light is also predicated of the intellect, and the intellect is said to see. Indeed, in response to the declarations made by some other person, another sometimes says that he sees it to be so, meaning that he understands. Because the intellect is spiritual, it cannot see in this way on account of natural light. For natural light does not last, but departs with the sun. It is apparent from this that the intellect has another light than the eye, and that that light comes from another origin.
