All of you sitting here now are in constant intercourse with the dead, only ordinary consciousness knows nothing of it because it proceeds in the sub-consciousness. Clairvoyant consciousness does not charm anything new into being; it merely brings up into consciousness what is present all the time in the spiritual world. All of you are in constant intercourse with the dead.
