Tulpas and Other Created Beings, part 2

We've gone back and forth over the question of whether poltergeists are a kind of tulpa. We're still not sure. Poltergeists are often created when traumatized kids externalize their trauma; seems to us that you've got a thoughtform there. But sometimes other spirits act like poltergeists, so it's hard to nail down the differences. What we do know is that a tulpa isn't anchored to anything the way a spirit is. There's no bones to burn or haunted objects to destroy.
In the case of the particular tulpa we dealt with, a guy named Mordechai Murdock, we found out that he was created, in a way, by the Internet. Some yahoos in Richardson, Texas, faked up a haunted house/murdering spirit story, and then some I-want-to-believe types had bought the story and put it up on a Web site. Enough people believed in that-presto!-the fictional killer became real. Once we knew that, we went back and looked at some of the loony graffiti painted all over the house and found a Tibetan spirit sigil used in mystical traditions to focus thought and belief. That's how we got our tulpa, we thought, and decided that maybe if we destroyed the sigil, we'd get the tulpa.
No such luck. Once created, tulpas have a life of their own. But what we figured out was that since the tulpa is a product of intense and focused belief, if you change what its creator (in this case creators) believe, then you change the tulpa. So we put out a nerd-grapevine memo that old Mordechai had shot himself and was still so scared of guns that a consecrated iron bullet would kill him. That almost worked-the bullets slowed him down for a minute, anyway-but the server crashed and so did everyone's belief in that particular bit of the Mordechai story.
So what did we do? We went back to basics. Burned the goddamn place down around his ears.
Once a tulpa achieves physical form it starts acting like a rebellious teenager. More often than not, it wants to get out from under the control of its creator, and you can guess where that goes. In this case, its creators were distributed all over the world, so that wasn't a problem, but take the lesson to heart. If you're sitting at home right now thinking really hard about creating a tulpa with those certain qualities you find missing inn your current friends and loved ones, remember: Life isn't like Weird Science. It's more like Frankenstein.
