10200. 'Morning by morning' means whenever a state of love in clearness exists. This is clear from the meaning of 'morning' as a time when a state of love in clearness exists, dealt with in 10134, so that 'morning by morning' or every single morning means whenever that state exists. It has been shown several times before that in heaven states of love and light, that is, of goodness and truth, follow one another in sequence unceasingly, just as on earth morning, midday, evening, and twilight do, and as spring, summer, autumn, and winter do. It has also been shown that those states are the origin from which these times of day and seasons of the year arise; for things that come into being in the world are images of the realities that exist in heaven. This is so because everything natural comes into being from what is spiritual, that is, from what is Divine in the heavens. From this it is evident what the variations of the states in heaven are like, for one comes to know what they are by comparison with the states of heat and light that exist in the world, heat in the heavens being the good of love coming from the Lord and the light there being the truth of faith coming from the Lord. States there follow one another in this kind of way to the end that angels may constantly grow more perfect; for as they pass through those states they experience all varieties of goodness and truth and are endowed with them. The differences furthermore in the varieties of the good of love and truth of faith there are like the differences of heat and light in all the particular regions or climates of the planet; that is to say, those near the equator are different from those further away in either direction from it, and they are different from one day to the next, and from one year to the next. What is exactly similar or the same does not ever return; for it has been provided that nothing shall ever be exactly the same, neither in the spiritual world nor in the natural world; and this enables perfection to increase constantly.

So that an even better knowledge may be had of the nature of representatives in the next life, that is to say, of the things that are seen in the world of spirits, let several examples also be given. When with angels a discussion is taking place about matters of doctrine regarding charity and faith, there is sometimes seen in that lower sphere where the corresponding community of spirits is situated the visible idea of a city or of cities with palaces in them. The architecture of these is so astounding that you would say architectural art itself existed there and was the inspiration of everything there. In addition the houses there are of varying appearance. And the marvel of it is that in every single palace or house not even the smallest point or tiniest visible detail exists that does not represent some aspect of the idea and discussion among the angels. From this it becomes clear how countless the details are which they contain, and also what was meant in the Word by the cities seen by prophets - what is meant by the Holy City or New Jerusalem, and also by the cities mentioned in the prophetical part of the Word, namely matters of doctrine regarding charity and faith, 402, 2449.
