5983. That man has communication with hell and with heaven through the two spirits and the two angels, may be seen from the fact that in the other life one society cannot have communication with another, or with anyone, except through spirits who are sent forth by the societies. These emissary spirits are called Subjects, for through them as subjects the societies speak. To send forth subjects to other societies, and in this way to get communication, is one of the familiar things of the other life, and is very well known to me from the fact that subjects have been sent to me a thousand times, and that without them the societies could not know anything appertaining to me, and could communicate to me nothing appertaining to themselves. This shows that the spirits and genii with man are nothing but subjects through whom he has communication with hell, and that the celestial and spiritual angels are subjects through whom he has communication with the heavens.
