Angels do not experience birth and death in the sense we generally understand them; yet there is only one being: God, who is above birth and death; all else is subject to the law of birth and death. The difference between the earth plane and the angelic plane is very great; but there is a time of youth and a time of age in everything, a time when the fruit is unripe and a time when it is ripe; and so it is with the angels, though there is no comparison possible between the life of angels and that of human beings, human life being too limited.
