4626. When any spirit is approaching, even though still a long way off and out of sight, his presence is detected, as often as the Lord allows it to be, from a certain kind of spiritual sphere. From that sphere one recognizes what his life is like, what his affection is like, and what his faith is like. Angelic spirits with keener perception know from his sphere countless things about the state of his life and faith, as has been demonstrated to me many times. When it pleases the Lord these spheres are also converted into odours; one smells quite distinctly an actual odour. The reason those spheres are converted into odours is that odour corresponds to perception and that perception is so to speak spiritual odour, from which also [natural] odour descends. But see what has been brought forward already on these matters - regarding spheres, in 1048, 1053, 1316, 1504-1519, 1695, 2401, 2489, 4464; perception, in 483, 495, 503, 521, 536, 1383, 1384, 1388, 1391, 1397, 1398, 1504, 1640; and odours produced by these, in 1514, 1517-1519, 1631, 3577.

1388. The second kind of perception, as has been stated, is common to all, existing with angels to the height of perfection, and with spirits according to the particular character of each one; that is to say, they know the character of another as soon as he approaches, even when he does not say a word. It shows itself immediately by means of a certain remarkable influx. A good spirit is recognized not only from the goodness within him but also from the faith there, and from each word he uses as he is speaking, while a wicked spirit is recognized from his wickedness and unbelief, and from each word he uses as he is speaking. They are recognized so plainly that one could never be mistaken. Something similar occurs among men who likewise, from another person's gestures, looks, and speech, are sometimes able to know what he is thinking, even though something different is expressed in his speech. With man such knowledge is natural, but it has its origin in and receives its character from that which exists in spirits, and so from the spirit of the individual himself and from his communication with the world of spirits. This communicative perception from this source derives in the first place from the Lord's will that all goods should be communicable and that all people should be stirred by mutual love and so be happy. This being so, such perception reigns universally among spirits also.
