"That sixth center of energy," he said, "doesn't quite belong to man.
You see, we human beings are under siege, so to speak. That center has
been taken over by an invader, an unseen predator. And the only way to
overcome this predator is by fortifying all the other centers."



"Isn't it a bit paranoiac to feel that we are under siege, don Juan?" I asked.



"Well, maybe for you, but certainly not for me," he replied. "I see
energy, and I see that the energy over the center on the top of the head
doesn't fluctuate like the energy of the other centers. It has a
back-and-forth movement, quite disgusting, and quite foreign. I also see
that in a sorcerer who has been capable of vanquishing the mind, which
sorcerers call a foreign installation, the fluctuation of that center
has become exactly like the fluctuation of all the others."
