Just as in our life there is a time when we grow taller, broader, stronger, and everything in us increases, and then, when the limit is reached, we do not grow any more and become weaker every day, so it is with the angels. Only, the life of the angels is much longer than man's life. Theirs is a life of illumination and of praise; they are much nearer to the universal, everlasting sound, the universal, eternal light, much nearer to God, than we are. They have luminous bodies, as solid, as concrete, as the light one sees. The speed of a journey in the heavens is also much quicker and cannot be compared with that of the lower world; it is quickest in the heaven of the angels.
