Man has a dark side. It's called stupidity. In the same measure that ritual forced the average man to construct huge churches that were monuments to self-importance, ritual also forced sorcerers to construct edifices of morbidity and obsession. As a result, it is the duty of every nagual to guide awareness so it will fly toward the abstract, free of liens and mortgages.
Ritual can trap our attention better than anything I can think of. But it also demands a very high price. That high price is morbidity; and morbidity could have the heaviest liens and mortgages on our awareness.
Human awareness is like an immense haunted house. The awareness of everyday life is like being sealed in one room of that immense house for life. We enter the room through a magical opening: birth. And we exit through another such magical opening: death.
Sorcerers, however, are capable of finding still another opening and can leave that sealed room while still alive. A superb attainment. But their astounding accomplishment is that when they escape from that sealed room they choose freedom. They choose to leave that immense, haunted house entirely instead of getting lost in other parts of it.
Morbidity is the antithesis of the surge of energy awareness needs to reach freedom. Morbidity makes sorcerers lose their way and become trapped in the intricate, dark byways of the unknown.

Stalkers who intend appearances are performers who are being coached by the spirit itself. The teacher's reason for training an apprentice as he does is freedom. He wants their freedom from perceptual convention. And he teaches them to be artists. Stalking is an art. For a sorcerer, since he's not a patron or a seller of art, the only thing of importance about a work of art is that it can be accomplished.
