What is the driving force behind those who believe it is evil? Is it Hollywood's portrayal of it in movies like Witch Board, the Exorcist, and more recently Ouija? Is it because of some traumatic experience they had as teenagers, when they used it with their friends? Or is it because of their religious beliefs?
Whatever it is they are quite adamant about it. When pressed for a reason the number one answer is: "You don't know what will come through." If this is true, then most of the methods we use in paranormal investigating are just as dangerous. Whether it is EVP's, Ghost Boxes, K-2 meters, loose flashlights, or even asking for a sign from a spirit, they all fall into that same category. You are inviting spirit to come through.
You may not agree with me and many don't but I will tell you like I tell all of the people I work with: "If you are not comfortable in doing something, then DON'T DO IT!"
Whether in paranormal investigating or life in general, Trust you heart! It is seldom wrong!
And that is just my thoughts...
Thanks for listening!
