The soul may be likened to a ray of the sun; so the souls of the angels, being not adorned with a physical garb, are as flames themselves. The scriptures therefore say that the angels are made of Nur or light; Nur is specially that light which comes from the divine Sun, the spirit of God. All souls are made of that essence which is the essence of the whole manifestation; and the quality of that essence is that it absorbs all that is around it, and in time develops so that it will emerge into its own element, which is the divine.
