5411. And Benjamin, Joseph's brother. That this signifies the spiritual of the celestial, which is the intermediate,* is evident from the representation of Benjamin, as being the spiritual of the celestial (as may be seen above, n. 4592; and also that the spiritual of the celestial is the intermediate). In general it should be known that the internal cannot have communication with the external, and the converse, unless there is an intermediate; consequently that truth from the Divine, which is "Joseph," cannot have communication with truths in general in the natural, which are the "sons of Jacob," without the intermediate represented by Benjamin, and called the "spiritual of the celestial." An intermediate, to be such, must partake of both the internal and the external. The reason why there must be an intermediate is that the internal and the external are most distinct from each other, and so distinct that they can be separated, just as man's ultimate external, which is the body, is separated when he dies from his internal, which is his spirit. The external dies when the intermediate is sundered, and the external lives when the intermediate is between; and just so far and in such a way does the external live, as is the intermediate between. As Jacob's sons were without Benjamin (that is, without the intermediate), therefore Joseph could not manifest himself to his brethren; and for the same reason spoke hardly to them, calling them spies, and putting them in custody; and for the same reason also they did not know Joseph.
 But what is the nature of this intermediate represented by Benjamin and called the spiritual of the celestial, cannot be described so as to be apprehended, for there is a want of knowledge about the celestial of the spiritual, which is "Joseph," and about the truths of the church insofar as they are only memory-knowledges, which are the "sons of Jacob;" hence also about the spiritual of the celestial, which is "Benjamin." But in heaven the nature of this intermediate appears as in clear day, being there shown in the light of heaven, in which at the same time is perception by means of unutterable representatives; for the light of heaven is intelligence itself from the Divine, and from it there is perceptive power in regard to everything that is represented by means of this light. This is not the case with the world's light, which has nothing of intelligence in it; but by its means understanding is induced by the influx of the light of heaven into it, and at the same time by the influx of the perception that is in the light of heaven. Hence it is that man is so far in the light of heaven as he is in intelligence, and that he is so far in intelligence as he is in the truths of faith, and that he is so far in the truths of faith as he is in the good of love; consequently that man is so far in the light of heaven as he is in the good of love.
