Such personalities will concentrate their main activities in such a way that they can best affect conceptual thought, and bring about necessary changes. Many large families are representative of this group. They appear and reappear in your histories, always as dominant and significant entities. Here the family represents an entity who has taken upon itself the nurturing of your civilization. Knowing intuitively those changes which must come about in your future, they try to bring them about by appearing in your past; though to them your future and the past are the same they must still work within probabilities, you see, and what they are doing is affecting probabilities within your system. Even your time is basically plastic, though it does not seem so to you.
