God is light
God is light, and to those who have entered into union with him he imparts of his own brightness to the extent that they have been purified. When the lamp of the soul, that is, the mind, has been kindled, then it knows that a divine fire has taken hold of it and inflamed it. How great a marvel! Man is united to God spiritually and physically, since the soul is not separated from the mind, neither the body from the soul.
