The light hath a center and if one desire to seek it otherwise but from
the center, he can never attain to it. In this solar system the source of
light is the sun and every light is acquired from it; even the lamps of
the night are ignited through the sun, for if there were no sun the trees
would not grow nor the mines develop, so that the oil be extracted from
those trees and mines, and the lamps of the night be lit by it. Is it
possible that one attain to the light in this globular sphere without the
mediation of the sun? No, by the life of God! To suppose it, is pure
imagination. But the truth is this: The main source of the lights is the
sun and the rays are shed from it upon all the regions.
