What does the light of God represent?

Everything joins in beautiful series in the spiritual world.

No arbitrary forms, freaks or signs. One thing is joined to another, a beautiful portion of a perfect whole.

Even the lives you think you have left behind, evil, dark, troubled, full of pain, you see them illumined by heavenly light and perceive that every step, even those that seemed the farthest astray, was ordered by the same law of Fitness, and by the transfiguring power of Infinite Love and Wisdom becomes, incredible as it seems, a proper part of a beautiful whole.
