If the Soul has the same nature as Light, it would be refined and sent up as the Light.

Now wise physicians prove to us—and the limbs with the veins bear them witness—that the power of food pervades the body. But if the Light is refined little by little and goes out, it is clear that it is a Nature which is dissolved and scattered. And so if the Soul is of the same nature, how does it too not go out in the Refining ? For it must be that the Nature of the Soul itself is capable of dissolution just as the Nature of Light as. How. is it that the Light goes out while the Soul remains ? and who gave to the Soul this indissoluble fixity ? If this belongs to its nature, how is this Element partly fixed and partly not, partly dissolvable and capable of being scattered, partly fixed and massed together ? For if the Nature was a fixed one from its beginning, the Sons of Darkness when they ate it—if they ate it—would not be able to dissolve its Nature. For just as they could not annihilate its Being so that it should no longer be in existence—for lo, it is in existence—so they would be unable to dissolve the fixity of its Being.
