"There will be human beings of greater intelligence but who do not represent the human family."
"Even now, there are hybrid individuals, part-human, part-alien, walking in your world. There are not many of them, but their numbers will grow in the future. Perhaps you will meet one some day. They will look the same as you but be different. You will think they are human beings, but something essential will seem to be missing in them, something that is valued within your world. It is possible to be able to discern and to identify these individuals, but in order to do so, you would have to become skilled in the mental environment and learn what Knowledge and Wisdom mean in the Greater Community."
