The relationship of the supermen, or great spiritual hierarchy, to the human race is that of teachers, guardians and directors. They superintend human evolution. But this does not mean in the very least the relationship that is expressed in the term "spirit guides" so frequently use by the spiritualist. That is a totally different thing. They seem to imply that the "spirit guide" gives direct instructions or orders to the person known as a "medium." If we were all thus controlled and directed what would become of free will? Evolution can proceed only if we use our initiative in the affairs of life. If we were to be directed by the wisdom and will of others we would not evolve at all. We would be merely automata directed by others, and no matter how great they were we could never thus develop our judgment and self-reliance. It is not thus that the great spiritual hierarchy directs human evolution. It is, in part, by working with mankind en masse and bringing mental and moral forces to play upon them, thus stimulating latent spiritual forces from within. It is also by directly, or indirectly placing ideals instead of commands before the race. In another direction it is actual superintendence, or administration, or teaching, in a way that does not interfere with one's initiative or will. If the soul is to evolve it must have liberty--even the freedom to make mistakes. It is sometimes asked why, if the supermen exist, those who are in incarnation do not come out into the world and give us ocular evidence of the fact. It is pointed out that they could speedily convince the world by a display of superphysical force. But they are probably not in the least interested in convincing anybody of their existence. They _are_ interested in raising the general level of morality, of course, but such an exhibition would not make people morally better. The work of the supermen can best be done from higher planes than the physical. As for the very small number of the supermen who take physical bodies to better do their special work, they can best accomplish it from secluded places; and if they sometimes have reason to come out into the seething vibrations of our modern civilization it is easy to understand that they would not be conspicuously different from other men, to the ordinary observer.
