A genuine internalization of such rationales entails a transformation, a different response to the world of everyday life. Shamans found out that the initial thrust of this transformation always occurs as an intellectual allegiance to something that appears to be merely a concept, but which has unsuspectedly powerful undercurrents. This was best described by don Juan when he said, "The world of everyday life cannot ever be taken as something personal that has power over us, something that could make us, or destroy us, because man's battlefield is not in his strife with the world around him. His battlefield is over the horizon, in an area which is unthinkable for an average man, the area where man ceases to be a man."

He explained those statements, saying that it was energetically imperative for human beings to realize that the only thing that matters is their encounter with infinity. Don Juan could not reduce the term infinity to a more manageable description. He said that it was energetically irreducible. It was something that could not be personified or even alluded to, except in such vague terms as infinity, ‘lo infinito.’

Little did I know at that time that don Juan was not giving me just an appealing intellectual description; he was describing something he called an energetic fact. Energetic facts, for him, were the conclusions that he and the other shamans of his lineage arrived at when they engaged in a function which they called seeing: the act of perceiving energy directly as it flows in the universe. The capacity to perceive energy in this manner is one of the culminating points of shamanism.

According to don Juan Matus, the task of ushering me into the cognition of the shamans of ancient Mexico was carried out in a traditional way, meaning that whatever he did to me was what was done to every shaman initiate throughout the ages. The internalization of the processes of a different cognitive system always began by drawing the shaman initiates' total attention to the realization that we are beings on our way to dying. Don Juan and the other shamans of his lineage believed that the full realization of this energetic fact, this irreducible truth, would lead to the acceptance of the new cognition.

The end result which shamans like don Juan Matus sought for their disciples was a realization which, by its simplicity, is so difficult to attain: that we are indeed beings that are going to die. Therefore, the real struggle of man is not the strife with his fellowmen, but with infinity, and this is not even a struggle; it is, in essence, an acquiescence. We must voluntarily acquiesce to infinity. In the description of sorcerers, our lives originate in infinity, and they end up wherever they originated: infinity.

Most of the processes which I have described in my published work had to do with the natural give and take of my persona as a socialized being under the impact of new rationales. In my field situation, what was taking place was something more urgent than a mere invitation to internalize the processes of that new shamanistic cognition; it was a demand. After years of struggle to maintain the boundaries of my persona intact, those boundaries gave in. Struggling to keep them was a meaningless act if it is seen in the light of what don Juan and the shamans of his lineage wanted to do. It was, however, a very important act in light of my need, which was the need of every civilized person: to maintain the boundaries of the known world.

Don Juan said that the energetic fact which was the cornerstone of the cognition of the shamans of ancient Mexico was that every nuance of the cosmos is an expression of energy. From their plateau of seeing energy directly, those shamans arrived at the energetic fact that the entire cosmos is composed of twin forces which are opposite and complementary to each other at the same time. They called those two forces animate energy and inanimate energy.

They saw that inanimate energy has no awareness. Awareness, for shamans, is a vibratory condition of animate energy. Don Juan said that the shamans of ancient Mexico were the first ones to see that all the organisms on Earth are the possessors of vibratory energy. They called them organic beings, and saw that it is the organism itself which sets up the cohesiveness and the limits of such energy. They also saw that there are conglomerates of vibratory, animate energy which have a cohesion of their own, free from the bindings of an organism. They called them inorganic beings, and described them as clumps of cohesive energy that is invisible to the human eye, energy that is aware of itself, and possesses a unity determined by an agglutinating force other than the agglutinating force of an organism.
