3890. It has been occasionally observed above that heaven or the Grand Man is distinguished into innumerable societies, and in general into as many as there are organs and viscera in the body; and that each particular society belongs to one of these organs and viscera (see n. 3745). Also that the societies, although innumerable and various, nevertheless act as a one; just as all things in the body, although these are various, act as a one. The heavenly societies that belong to the province of the heart are the celestial societies, and are in the midst, or in the inmosts; but those which belong to the province of the lungs are the spiritual societies, and are round about, and are in the exteriors. The influx from the Lord is through the celestial societies into the spiritual ones, or through the middle into the circumferences, that is, through inmosts to exteriors. The reason of this is that the Lord inflows through love or mercy, whence comes all that is celestial in His kingdom; and through love or mercy He inflows into the good of faith, whence comes all that is spiritual in His kingdom; and this with unspeakable variety; but the variety does not arise from the influx, but from the reception.
