3861. 'And she called his name Reuben' means the essential nature of it, which is described. This is clear from the meaning of 'name' and 'calling the name' as the essential nature, dealt with in 144, 145, 1754, 1896, 2009, 2724, 3006, 3421. That nature itself is described by the statement, 'Because Jehovah has seen my affliction, for now my husband will love me', the literal meaning of the name Reuben. Spiritually however all names in the Word mean real things, as has been shown often, see 1224, 1264, 1876, 1888; and among me ancients when a name was given it meant some state, 340, 1946, 2643, 3422. Here it will be seen that the names of all the sons of Jacob mean the universal attributes of the Church. Also one specific universal attribute has been combined within each name, but what that attribute is no one can possibly know unless he knows the internal sense embodied in the words from which each son's name is derived. That is, he needs to know the internal sense embodied in 'has seen' from which Reuben is derived, and in 'has heard' from which Simeon is derived, and in 'has clung to' from which Levi is derived, and in 'to confess' from which Judah is derived, and so on with all the other sons.

The warmth of heaven comes from the Sun of heaven, which is the Lord, and the warmth of the world comes from the sun of the world, which is plainly visible before our eyes. The warmth of heaven manifests itself before the internal man by means of spiritual loves and affections, whereas the warmth of the world manifests itself before the external man by means of natural loves and affections. The first form of warmth constitutes the life of the internal man, whereas the second constitutes that of the external man; for without love and affection a person cannot live at all. Between those two forms of warmth also correspondences exist. Those two forms of it become loves and affections from the influx of the Lord's life, and therefore they show themselves to man as if they were not forms of warmth, when in fact that is what they are. For if a person did not receive warmth from the Lord's inflowing life, both in his internal man and in his external man, he would instantly fall down dead. These considerations are evident to anyone from the fact that to the extent a person is fired by love he also becomes warmer, and to the extent love departs he cools off. It is from this warmth that a person's will lives, but from the light spoken of above that his understanding lives.
