All the angels are amazed at humans, who through their holy works appear clothed with an incredibly beautiful garment. For the angel without the work of the flesh is simply praise; but the humans with their corporeal works are a glorification! Therefore the angels praise humans' work.
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."
