157. Every angel undergoes and passes through such changes of state and so does each society in general, yet each one there differently from another because they differ in love and wisdom, those in the middle being in a more perfect state than those round about as far as the boundaries; (see above n. 43 and 528). It would be rather long drawn out to specify the differences since each one undergoes changes in accordance with the quality of his love and faith. From this it comes about that while one may be in his clearness and delight, another is in his obscurity and lack of delight, and this, at the same time within the same society. So, too, the state differs in different societies, and will be different in the societies of the celestial kingdom from what it is in those of the spiritual kingdom. These changes of state differ in general like the variations of the states of the days in different climates on the earth, for with some it is morning when with others it is evening, and with some it is hot when with others it is cold, and vice versa.
