5586. 'Unless your brother is with you' means unless the intermediary is with you. This is clear from the representation of 'Benjamin' as the intermediary, dealt with in 5411, 5413, 5443. The intermediary represented by 'Benjamin' serves as the link between the internal and the external, that is, between the spiritual man and the natural man; also, it is the truth of good that goes forth from truth from the Divine, represented by 'Joseph'. This truth of good is called the spiritual of the celestial - 'Benjamin' being the spiritual of the celestial, see 3969, 4592. A person's internal and external are completely distinct and separate from each other; for his internal dwells in the light of heaven, his external in the light of the world. And being completely distinct and separate they cannot be joined together except through the intermediary which derives its existence from both of them.

2716. As for the second arcanum - that the obscurity with those who are spiritual is brightened by light from the Lord's Divine Human - it is an arcanum that cannot be explained intelligibly, for it is the influx of the Divine that would have to be described. But one may gain some idea of it simply from the consideration that if the Supreme Divine Itself were to flow into the kind of good that has been described - good that has been defiled by so many evils and falsities - It could not be received; and if anything were received by someone possessing such good he would experience hellish torment and so perish. But the Lord's Divine Human is able to enter into those persons and to brighten such good, much as the sun shining into thick clouds produces in the early morning lovely signs of the dawn breaking. Yet the Lord is unable to present Himself before them as the light of the sun, only as the light of the moon. From this it may be seen that the reason the Lord came into the world was to save those who are spiritual, see 2661.
