155. Angels are not constantly in the same state in respect to love, and in consequence in the same state in respect to wisdom; for all their wisdom is from their love and in accordance with their love. Sometimes they are in a state of intense love, sometimes in a state of love not so intense. The state decreases by degrees from its greatest degree to its least. When in their greatest degree of love they are in the light and warmth of their life, or in a clear and delightful state; but in their least degree they are in shade and cold, or in an obscure and undelightful state. From this last state they return again to the first, and so on, these alternations following one after another with variety. There is a sequence of these states like the varied states of light and shade, or of heat and cold, or like morning, noon, evening, and night, day after day in the world, with unceasing variety throughout the year. There is also a correspondence, morning corresponding to the state of their love in its clearness, noon to the state of their wisdom in its clearness, evening to the state of their wisdom in its obscurity, and night to a state of no love or wisdom. But it must be understood that there is no correspondence of night with the states of life of those in heaven, although there is what corresponds to the dawn that precedes morning; what corresponds to night is with those in hell.{1} From this correspondence "day" and "year" signify in the Word states of life in general; "heat" and "light" signify love and wisdom; "morning" the first and highest degree of love "noon" wisdom in its light; "evening" wisdom in its shade; "dawn" the obscurity that precedes the morning; and "night" the absence of love and wisdom.{2} {Footnote 1} In heaven there is a state corresponding to the dawn that precedes morning, but no state corresponding to night (n. 6110). The "dawn" signifies a middle state between the last and the first (n. 10134). {Footnote 2} Alternations of state in respect to enlightenment and perception occur in heaven, like the times of day in the world (n. 5672, 5962, 6110, 8426, 9213, 10605). In the Word "day" and "year" signify all states in general (n. 23, 487, 488, 493, 893, 2788, 3462, 4850, 10656). "Morning" signifies the beginning of a new state, and a state of love (n. 7218, 8426, 8427, 10114, 10134). "Evening" signifies a state of declining light and love (n. 10134, 10135). "Night" signifies a state of no love or faith (n. 221, 709, 2353, 6000, 6110, 7870, 7947). 156. Together with the state of the angels' interiors which pertain to their love and wisdom, the states of various things that are outside of them and that they see with their eyes are changed; for the things outside of them take on an appearance that is in accord with the things within them. But what things these are, and what kind of things they are, shall be told presently in the chapter on Representatives and Appearances in Heaven.
