To meet the Gods- the sacred forces worshiped by a people face-to-face- was not for everyone. To regain intimate communication with the dead, to see and experience the afterlife-condition that awaited all in death, to know one's place, to know how all the world came to be and whence came the wretched conditions that now proliferated: that person would have knowledge best reserved for the dead, and the Gods themselves.
No one with that kind of knowledge will submit to slavery. They will not submit to manipulation, and they will not be carried away by the shallow sentiments that rule the hearts of most. For an individual man or woman, that was a precious gift, and if they had the wits to remain judiciously silent, it was the most precious of things. But society as a whole could not have such gifts; such a society would never survive. The force of truth appears as a grim destroyer when a society is carefully based on complex systems of untruth.
