Most people think he reads peoples eye movement and expressions.....it's neither of them ways....
The way I believe it works because this ability comes to me, but unexpectedly.....I can read peoples thoughts when I can see them, and at times it can be every person in the room at the same time, it's when I am center of attention, it's when I am thinking of that person the same time they are thinking of me.....it's basically their countenance, same as aura that displays their emotions and feelings telepathically.....the answers then just pop in your head, word for word.....this happens to me when I can see spirits too, and they don't have any details on their face to read, but their personal thoughts pop in my head......so this is the way it works, it's their aura that displays their feelings and emotions telepathically.....one way unless the other person has the same ability......I once communicated with this one spirit telepathy back and forth, it is the fastest way to communicate when your able to do it.
