"That wall is mostly empty space" was all he said, my world has never been the same.I will never forget the explosion in my mind and body,something had opened and life was suddenly new and exciting. That was over thirty years ago, it all came back to me when listening to an open focus exercise that asked. "Can you imagine that an atom consists of a nucleus with electrons revolving about it. Can you imagine that the diameter of the atom is 200,000 greater than the diameter of the nucleus. Can you imagine that the atom is mostly empty space? Can you imagine that your body is made of atoms? Can you imagine that your body is mostly empty space?" Again an explosion of possibilities !
