At risk of beating this drum too much.........I just finished The Siren Call of Hungry Ghosts. If one takes the author at his word, you can draw several conclusions. (I hope its OK to post excerpts)
1. Whatever speaks through a medium or channel cannot be 100% trusted, no matter how evidential.
A medium's testimony from the epilogue: "They are masters of deception; they are articulate and eloquent with vast knowledge of philosophy at their disposal. whether fabricated or otherwise. They are able to cooperate and liaise sufficiently with others of their kind to devise strategies against us and maintain a continuity of information given to us. They have apparently limitless powers of precognition and access to any information they choose- past. present or future--enabling them, among other things, to impersonate whomsoever they wish with ease."
2. That's bad enough, but maybe "love and light" aren't all they're cracked up to be either.
Another quote from the same medium, emphasis mine,, "My guides manifested as they do to all mediums and channelers, as beings of great wisdom with a desire to help mankind. I am sure you can fully appreciate the intense feelings of love and well-being you receive from these beings during direct, mind-to-mind contact. It is heady stuff that hooks you totally. Right from the beginning, my guides appeared to groom me for a 'great work' that I had supposedly been born to perform as a spiritual teacher."
This medium also believes paranormal activity, be it "spirit contact", UFOs, fairies or whatnot through the ages, is all connected and is being used to influence humankind and not in a good way. Granted, that goes further than the author's conclusions, but it does make sense to me. I'm listening to a podcast interview with Michael Horn talking about the UFO contacts with Billy Meier. Some of it sounds good, "we are all one", "evolving towards the source" etc., but right along with that comes a veritable crapstorm of lies and misinformation about human origins that makes absolutely no sense. They have also billed him as the 7th and final prophet following the likes of Elijah, Jesus and Mohammed. Sound familiar? I've seen it in some NDE accounts as well. Someone comes back with an amazing story, but there are parts of it that simply don't make sense with logic, history or how things work. (I'm thinking of Nanci Danison here) Plus they are told they have a "work" to do.You see this exact same thing all through this whole paranormal/afterlife genre. So what are "they" after? Where in the world are the good guys if there are any? Is "love and light" really the answer?
