The Parallets between Gnostic and Castaneda by John Lash

"The parallels between Gnostic materials and the new Toltec sorcery of Carlos Castaneda are striking and present sobering insights on the human condition, if nothing else. What can we do about the topic of topics, predation? “All we can do is discipline ourselves to the point where they will not touch us,” Don Juan advises. Significantly, he says will not, not can not. He also says that the alien predators are the way the universe tests us, as just noted. It follows that the intent to arrange our minds and lives so that the flyers/Archons are not willing to intrude on us is the capital exercise, the primary test in progress for humanity."
