3664. It was observed that above those to whom David strove to come, there were spirits still more subtle, for David is of such a quality from spirits having spoken through him while he lived in the body, that he is able by effort to come to them. It was moreover perceived also that they are those who rule the spirits now spoken of as being more deceitful than others, and called sirens, because they are above them. Whether they are from this earth or from those in other earths through whom spirits speak as they did through David, and are at the same time in contrariety to conjugial love, I know not. They do not clearly appear, but they flow into the left eye, into which, even now also while I am beginning to write, they strike a degree of pain. They are averse to being detected, as they wish to practice their deceits in the most clandestine manner. -l748, October 23.
