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."
Live your life so that the fear of death can never enter your heart. When you arise in the morning, give thanks for your food and the joy of living. And if perchance you see no reason for giving thanks, rest assured the fault is in yourself.
