I have done automatic writing since I was 15 years old and now I'm 50. It was easy for me to develop because as my mother would say I was always day dreaming. No bad spirits come to me because I don't have negative ideas about it. I don't believe that an evil spirit will come to me. I believe that they love us and want to be with us. I'm a loving person and don't do it for selfish reasons.
They talk by moving my hand. They help me with life issues. All goes well as long as you don't have an ego thing going in your mind. To learn more about ego read in Buddhist teachings and about karma.
There was a book that came out in the seventy's by a female author with the last name Montgomery. It was called " A Search for The Truth". She did her writing by using a typewriter.
There's not much information on the web. I don't like to see people misunderstand the gift.
In order to develop the gift, your family on the other side has to see that you are sincere and have only good intentions for using it.
The best way to develop it is to first get good at meditation. You have to be able to go into an altered state. Its like daydreaming. In that altered state you won't remember the questions you had so write them down ahead of time.
Some time when your not trying real hard to do it and your feeling tired and bored then it will work.
You have the same ability to eric. He ca talk to spirits/ghosts by means of writing them or drawing their faces down. He was a professional psychic here at my country. He was a fellow countryman but I don't know him very well 😐 😊
