“I suspect that these mind vampires specialize in finding races who have almost reached this point of evolution, who are on the brink of achieving a new power, and then feeding on them until they have destroyed them. It is not their actual intention to destroy – because once they have done this, they are forced to seek another host. Their intention is to feed for as long as possible on the tremendous energies generated by the evolutionary struggle.
Their purpose, therefore, is to prevent man from discovering the worlds inside himself, to keep his attention directed outwards…”
