Short answer: yes.
(But so can just about anything.)
Now for the longer answer: Spiritualist work ain’t a corny horror movie. You don’t break out the Ouija board and suddenly find your life taking a turn toward the plot of Final Destination or Serpent and the Rainbow (the movie; the book is fine). There are hazards, but they are almost always overstated by the opponents of spiritualist work. First rule? Don’t be a sucker. Second rule? Don’t be a sucker. Got that? That applies to mediums and spirits. Okay, let’s proceed to the juicier spiritual health issues.
Remember all these discussions of the daemon here? I’ll try not to repeat myself too badly for repeat readers, but the basic gist is that the daemon as the Yeatses understood it was a spirit that shapes our fate and our desire, that is bound to us for our life. As such it has a great deal to with out luck.
