24. Since spiritual sight is not given through the eyes of the flesh, the perception of things is not given by any ordinary light; indeed, material light is made for the material world. For the spiritual world there exists a special luminary, the nature of which is unknown to us, but which is, without doubt, one of the properties of the ethereal fluid affected by the visual perceptions of the soul. There is, then, material and spiritual light. The first has circumscribed focuses from luminous bodies; the second has its focus everywhere; therefore, there are no obstacles to spiritual sight. It is neither arrested by distance nor by the opacity of matter, nothing dims it. The spiritual world is then illuminated by a spiritual light which has its characteristic power, as the material world has its solar light.
