What is the meaning of the light of God?

I have, in my Spirit life, traversed the various districts of Spiritland.

Here the eye rests fondly on Nature's variegated fields of floral verdure, and there the little streamlet wimples along its rocky bed—

Here we have the majestic rivers pouring their rolling waters into the quiet and pellucid lakes that mirror, in their deep bosoms, the image of the passers-by, and there, sweet music lends its powerful aid to awaken hardened, benighted, dark souls to lift their eyes upwards towards Him who can dispel the thick clouds, which enshroud them—

To Him who is the Source of All Light, without whose loving beams they are powerless to burst through the pride-bound gate that shuts them out from the companionship of the truly happy.

—Hafed, Prince of Persia, in Spirit
