Societies of spirits sent me, or chose for themselves, spirits who were to be near me, whom I have earlier called mediums [405, 1254, 2316], for through them they know what is being thought and spoken. So on several occasions they have sent me their own spirits for the sake of communication, which would otherwise have been cut off. Spirits have an almost innate knowledge of this, for they all know it is true, as I have even been enabled to learn from evil spirits, who have their emissaries as communication centers round about, like a spider in its web, thereby establishing communications.
