I perceived or thought of the Light of God and in it suspended one small mote (or millions of motes to only one of which was my small mind directed), glittering white because of the individual ray from the Light which both held and lit it...And the ray was the Guardian Angel of the mote: not a thing interposed between God and the creature, but God's very attention itself, personalized...This is a finite parallel to the Infinite. As the love of the Father and Son (who are infinite and equal) is a Person, so the love and attention of the Light to the Mote is a person (that is both with us and in Heaven): finite but divine, i.e. angelic.
