"[With] the power of telepathy... complete silence greeted us as we joined the circle. [He] took my left hand and placed his right hand firmly on my cheek. His eyes engaged mine silently for a few seconds, then he said, "Welcome to our Alpha, Jon.... It is our custom to meet first with our eyes and minds, then with our touch, and lastly with our voices, if that seems desirable.
...Imagine the atoms that make up your being reaching lovingly, joyously out toward this person that you're greeting."
I realized another reason why members of [the New World] greet each other silently. They are using this silence to concentrate on the delightful nuances of telepathic contact, which removes all possibility of fear and distrust."
