Arcana Coelestia #9819
9819. 'And they shall make Aaron's garments' means through whom the spiritual kingdom exists. This is clear from the meaning of 'Aaron's garments' as a representative sign of the Lord's spiritual kingdom lying adjacent to His celestial kingdom, dealt with above in 9814. The reason why the wise at heart, filled with the spirit of wisdom, were to make those garments is that by these people those in the celestial kingdom are meant, and the spiritual kingdom is what springs from and so what covers that celestial kingdom like a garment next to the body, as also becomes clear from the things that have been stated in 9818.
Arcana Coelestia #2887
2887. Present with man all the time there are evil spirits and there are angels. By means of the spirits he communicates with the hells, and by means of the angels with the heavens. If those spirits and angels were taken away from him he would instantly lose the ability to will and to think, and so would not have any life. This may seem paradoxical, but is perfectly true. But the subject of spirits and angels present with man is in the Lord's Divine mercy to be discussed elsewhere.
