4803. A matter wholly unknown in the world and worthy of mention is this: The states in which good spirits and angels live undergo constant change and perfection. In this way they are conveyed to the more internal parts of the province in which they dwell, and so into more excellent functions. For in heaven purification takes place constantly, which is so to speak a new creation. Yet the situation is that no angel to all eternity can possibly attain complete perfection. The Lord alone is the perfect One, He being the root and the source of all perfection. Those who correspond to the mouth constantly wish to be speaking, for speaking gives them utmost pleasure. While undergoing perfection they are restricted to speaking nothing but that which is beneficial to companions, the community, heaven, and the Lord. The delight they take in speaking in that way grows in the measure that the desire to regard themselves in what they speak and to strive after wisdom from what is properly their own passes away from them.

9516. 'And their faces of a man towards his brother' means truth and good joined together. This is clear from the meaning of 'the face' as the interiors, at this point looking towards and being joined to, for when two are looking each towards the other they join themselves together on the level of interiors (interiors being meant by 'the face', 1999, 2434, 3527, 3573, 4066, 4796-4805, 5102, 5165, 5168, 5695, 9306); and from the meaning of 'man towards brother' as mutually, dealt with in 4725, so that truth joined to good is meant. For 'man' means truth, 3134, 3309, 3459, 4725, 7716, 9007, and 'brother' good, 367, 2360, 3303, 3803, 3815, 4121, 4191, 5409, 5686, 5692, 6756.

5695. 'And he washed his face' means that it took steps to ensure this. This is clear from the meaning of 'washing his face' here as taking steps to ensure that it remained unseen; for Joseph's face was washed, and so steps were taken by him to ensure that his tears remained unseen. The full implications of this will in the Lord's Divine mercy be stated further on; but let something be said at this point about the correspondence of a person's face with his interiors. His face is what is external serving to represent his interiors. For the face has been designed in such a way that a person's interiors may be seen there as if in a mirror that reflects things in a representative fashion; it has been so designed that another may know its owner's attitude of mind towards himself, so that the owner reveals his sentiments when he speaks not only through his speech but also through his face. This was the kind of face possessed by the most ancient people who belonged to the celestial Church, and it is the kind that all angels have. Angels have no wish to conceal from others anything they think, for they think solely of their neighbour's well-being. Nor do they have any thought hidden away which desires their neighbour's well-being for some selfish reason of their own.

[2] But those in hell, as long as they are not seen in the light of heaven, have a face other than the one that corresponds to their interiors. The reason for this is that during their lifetime they bore witness by means of their face to charity towards the neighbour solely for the sake of their own position and gain; they did not desire their neighbour's well being except insofar as it was identical with their own. Consequently the expression on their face is at variance with their interiors. Sometimes that variance is so great that feelings of enmity, hatred, and revenge, and the desire to murder are inwardly present, yet their face is set in such a way that love towards their neighbour is beaming from it. From this one may see how far people's interiors disagree at the present day with their exteriors, and why they resort to those kinds of practices to serve their own interests.
