Yah definitely it is true once you open your gateway in contacting the dead. The devil would always manage to capitalize on it. If you think that your contacting someone you love who just passed away you will definitely be susceptible of attacks from other spirits. We have no right to disturb the dead since they have there own struggle likewise with us who are still on earth. I believe on the paranormal but i refuse to interfere with them since it would alter their existince and that would create disturbances in the realmof the dead.
