There is a place in everyone that can carry the light. God has made it this way. God has not only given us the chance to carry the light, but has made it possible for us to kindle and strengthen the light in one another, passing the light along. This way God's light will shine forever in this world.
There are lights which ascend and lights which descend. The ascending lights are the lights of the heart; the descending lights are those of the Throne. The false self is the veil between the Throne and the heart, like springs toward like. Light ascends toward light and light descends upon light, and "it is light upon light."
