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.

3636. It is an entirely general and all-embracing law that the Lord is the Sun of heaven and that this is the source of all the light in the next life; that nothing at all from the light of the world is visible to angels and spirits, that is, to beings in the next life; and also that the light of the world which comes from the sun is to angels nothing else than thick darkness. From the Sun of heaven, or the Lord, comes not only light but also warmth; but these are spiritual light and spiritual warmth. The light that strikes their eyes is seen as light but it holds intelligence and wisdom within it since it is the outward manifestation of these. And the warmth is experienced by their senses as warmth but has love within it since it is the outward manifestation of that love. This being so, love is called spiritual warmth and is also the producer of the warmth which man's life possesses, while intelligence is called spiritual light and is also the producer of the light which his life possesses. From this all-inclusive correspondence all other correspondences are derived, for every single thing has regard to good which belongs to love and to truth which belongs to intelligence.
