I have noticed that whenever I saw pictures of Chico Xavier psychographing I saw him with his hand against his head. I thought that may have just been how he felt best when he communicated with spirits.
I read a passage in the book, Life Beyond the Veil, in The Lowlands of Heaven section. It was a communication to the Rev G. Vale Owen from his mother in the spirit world. His mother tells him the best method to hear her clearly in his mind. The bold words from G. Vale Owen:
“Place your hand against your head and you will notice that we are then able the more readily to speak to you so that you will be able to understand.
Yes, I helps you and us, both
I don’t understand a word of this.
Maybe not. There are many things you have yet to learn, dear, and what we are saying now is one of those things, little in itself but still of account. It is often these small things which help to success.
Now, while we are not over-anxious to explain the methods we employ in the transmission of these messages, because we can only make you understand imperfectly, still we may say this: the power we use is best described as magnetism, and by means of this vibrations of our minds are directed on your own. Your hand being so placed serves as a kind of magnet and reservoir in one, and helps us.”[i]
I hope this helps mediums understand some of the mechanism involved in communication between our physical world and the spirit realm.
Learn more about the spirit world and how it works by reading my book, Explore Your Destiny – Since Your Life’s Path is Predetermined. You will find out that we are all immortal souls who live the vast majority of our time in the spirit world. We are sent to earth to learn and to one day become a pure spirit.
