9215. 'It is his clothing for his skin' means that they also clothe relatively external things. This is clear from the meaning of 'clothing' as the sensory level in general or things on that level, as above; and from the meaning of 'skin' as that which is relatively external, which also clothes more internal things but still exists within those on the sensory level. What 'the skin' means, and who exactly correspond to the skin in the next life, see 3540, 5552-5559, 8977, 8980. The natural degree of the human mind has a rather internal level, a relatively external or middle level, and an outermost level. The more internal level of the natural is in contact with heaven; the middle or relatively external level is in contact on one side with the more internal, and through this with heaven, and on the other side with the outermost, and through this with the world, see 4009, 4570, 5118, 5126, 5497, 5649, 5707. The outermost level of the natural is that of the senses, which is meant here by 'clothing'. This level receives impressions of objects in the world and thereby serves more internal things. It is called 'his only covering' because it is the last and lowest and so is general to all, the relatively external or middle level of the natural being the one meant by 'skin'. From this it is evident that 'his clothing for his skin' means that the sensory level also clothes relatively external things. The fact that the sensory level is the last and lowest of a person's life, and so is a general covering, see 4009, 5077, 5125, 5128, 5767, 5774, 6201, 6313, 7442, 7693.

6624. Since man thinks on the level of the senses such things are obscure to him, so obscure indeed that he does not know what an idea is, in particular that thought is distinguished into separate ideas as speech is into words. For to man thought seems to be continuous, without separate parts; but in actual fact ideas constituting thought are the words that spirits use, and ideas constituting more internal thought are the words that angels use. And because ideas are the words they use to speak with, they are audible among spirits and angels. This explains why man's silent thought can be heard by spirits and angels, when it pleases the Lord that it should be. How perfect the ideas constituting thought are in comparison with the words composing speech may be recognized from the fact that a person can think more in a minute than he can speak or write in an hour. I have also recognized it from conversations with spirits and angels; for at such times I have in a single moment filled in the broad outlines of a subject with specific details, while my affection was engaged. The angels and spirits grasped every distinct detail, and many more that manifested themselves around that subject like a cloud.
