65. The way in which the evolution of these senses is effected shall also be told in a few words. But for the understanding of this it will be necessary to recall what has been said above about successive order and simultaneous order, namely, that in successive order what is celestial, what is spiritual, and what is natural follow one after another, from highest things in heaven down to ultimate things in the world, and that the same things are in the ultimate (which is natural) in simultaneous order, one next another from the inmost things to the outermost ones, and that in like manner there are successive senses of the Word, celestial and spiritual, simultaneously in the natural sense. When these things are comprehended, the way in which the two senses, celestial and spiritual, are evolved from the natural sense while a man is reading the Word may in some measure be unfolded before the understanding; for a spiritual angel then calls forth what is spiritual, and a celestial angel what is celestial, nor can they do otherwise, because such things are homogeneous and in accordance with their nature and essence.
