271. Arrayed in white garments, signifies all truths from good in the lower heavens. This is evident from the signification of "white garments," as being truths that invest, which specifically are true knowledges [scientifica] and cognitions (See above, n. 195, 196, 198); and because the lower heavens are in these truths, they are meant.

That "white garments" signify the lower heavens may seem strange to those who know nothing about appearances and representatives in heaven. All in the heavens are clothed according to truths, and lower truths correspond to garments, and because the lower heavens are in these truths, therefore the garments of the angels in the higher heavens also correspond to these. (But this arcanum may be more clearly understood from what is said and shown respecting the Garments in which the Angels are Clothed, in the work on Heaven and Hell 177-182; likewise from what was represented and signified by the garments of Aaron and his sons, explained in Arcana Coelestia 9814, 10068; as also by the garments of the Lord when He was transfigured, n. 9212, 9216)

177. The Clothes Angels Appear In

Since angels are people and live together the way people on earth do, they have clothes and homes and a great many other things: the difference, however, being that everything is more perfect for them because they are in a more perfect state. For just as angelic wisdom surpasses our wisdom so greatly as to be inexpressible, so too does everything that comes to their perception and sight, since everything perceived by and apparent to angels corresponds to their wisdom (see above, 173).
