143. Nowadays it may seem strange that 'beasts' and 'animals' in ancient times meant affections and similar things residing with man. But because people had heavenly ideas then, and because such things are also represented in the world of spirits by animals - by such animals in fact as resemble those affections - this alone is what they therefore understood when they spoke in this fashion. And this alone is what is meant in the Word whenever beasts are mentioned in general or in particular. The whole prophetical section of the Word is full of things such as these, and therefore anyone who does not know the particular meaning of any beast cannot possibly understand what the Word contains in the internal sense. But as slated already, there are two kinds of beasts - evil ones, because they are harmful, and good ones, because they are harmless. Good beasts, such as sheep, lambs, and doves, mean good affections. Here, because the subject is the celestial man, or the celestial-spiritual man, the same applies. The fact that 'beasts' in general means affections has been confirmed from several places in the Word quoted already in 45, 46. So there is no need of further confirmation.

6949. 'And it was made into a serpent' means the sensory and bodily level of a person's mind separated from the internal. This is clear from the meaning of 'a serpent' as a person who engages in reasoning based on sensory evidence, dealt with in 195-197, 6398, 6399, thus the sensory level of a person's mind. And since 'a serpent' means the sensory level it means the bodily also, for the sensory level acquires its perceptions from the bodily senses. And since the sensory level regarded in itself is such as is described immediately above in 6948, 'a serpent', which is the sensory level, also means all evil in general, 251, 254, 257. The use of 'a serpent' here to mean the sensory and bodily level of a person's mind separated from the internal or rational level is evident from the fact that Moses fled from before it, meaning a feeling of horror caused by it, as well as from the fact that this sign describes the state of those who belonged to the spiritual Church if they were not in possession of faith; for in that case their internal would be closed and no more of the light of heaven would flow in than would be sufficient to enable them to think on that separated sensory level and therefore speak on that level. This level, separated [from the internal], is the one on which all people think who defend falsities in opposition to truths, and evils in opposition to forms of good, in short all who in life pursue what is evil and who are consequently devoid of any faith since those who lead an evil life have no belief at all. People like this have greater ability than others to engage in reasoning and to convince others, especially the simple, because when they speak they draw on the illusions of the senses and worldly appearances. They also know how to demolish truths or hide them from view by means of illusions, on account of which cunning and deceitfulness are also meant by 'serpents'. When however the sensory level has become joined to the internal or has been made properly subordinate to the rational, 'a serpent' means shrewdness and circumspection, 197, 4111, 6398.
