You ask how it is possible for one mind to know the thoughts of another.  You think this is some kind of magic, as if your mind is jumping across empty space, entering the mind encased inside a physical brain, and reading the inner workings of that physical apparatus.  As long as you adhere to this thinking, so-called mind reading, or what is known as telepathy will hold a magical mystery to you.  It is only when you understand that there is no emptiness between your mind and that of another that the magic disappears and logic enters the picture.  All is consciousness.  There is no beginning and end to consciousness, only a flow … a spectrum of vibration.
 
The space between your mind and that of another is merely a ribbon of vibration.  Feel the vibration of the ribbon and hear the thoughts, feel the emotions, know the other.  It is not magic nor mysticism.  It is reality.  The reality is:  all is One.  You are a focus of Infinite Divine Consciousness.  What will you do with that understanding?
