Emanuel Swedenborg, Heaven and Hell — Chapter XX, The Garments with which Angels Appear Clothed
“ Their garments correspond to their intelligence, and therefore all in the heavens appear clothed in accordance with their intelligence; and as one is more intelligent than another so the garments of one surpass those of another. The most intelligent have garments that blaze as if with flame, others have garments that glisten as if with light; the less intelligent have garments that are glistening white or white without the effulgence; and the still less intelligent have garments of various colors. But the angels of the inmost heaven are not clothed. ”
