The power that governs the destiny of all living beings is called the Eagle, not because it is an eagle or has anything to do with an eagle, but because it appears to the seer as an immeasurable jet-black eagle, standing erect as an eagle stands, its height reaching to infinity. As the seer gazes on the blackness that the Eagle is, four blazes of light reveal what the Eagle is like. The first blaze, which is like a bolt of lightning, helps the seer make out the contours of the Eagle’s body. There are patches of whiteness that look like an eagle’s feathers and talons. A second blaze of lightning reveals the flapping, wind-creating blackness that looks like an eagle’s wings. With the third blaze of lightning the seer beholds a piercing, inhuman eye. And the fourth and last blaze discloses what the Eagle is doing.
The Eagle is devouring the awareness of all the creatures that, alive on earth a moment before and now dead, have floated to the Eagle’s beak, like a ceaseless swarm of fireflies, to meet their owner, their reason for having had life. The Eagle disentangles these tiny flames, lays them flat, as a tanner stretches out a hide, and then consumes them; for awareness is the Eagle’s food.
The Eagle, that power that governs the destinies of all living things, reflects equally and at once all those living things. There is no way, therefore, for man to pray to the Eagle, to ask favors, to hope for grace, The human part of the Eagle is too insignificant to move the whole. It is only from the Eagle’s actions that a seer can tell what it wants. The Eagle, although it is not moved by the circumstances of any living thing, has granted a gift to each of those beings.
In its own way and right, any one of them, if it so desires, has the power to keep the flame of awareness, the power to disobey the summons to die and be consumed. Every living thing has been granted the power, if it so desires, to seek an opening to freedom and to go through it. It is evident to the seer who sees the opening, and to the creatures that go through it, that the Eagle has granted that gift in order to perpetuate awareness.
For the purpose of guiding living things to that opening, the Eagle created the Nagual. The Nagual is a double being to whom the rule has been revealed. Whether it be in the form of a human being, an animal, a plant, or anything else that lives, the Nagual by virtue of its doubleness is drawn to seek that hidden passageway.
The Nagual comes in pairs, male and female. A double man and a double woman become the Nagual only after the rule has been told to each of them, and each of them has understood it and accepted it in full.
To the eye of the seer, a Nagual man or Nagual woman appears as a luminous egg with four compartments. Unlike the average human being, who has two sides only, a left and a right, the Nagual has a left side divided into two long sections, and a right side equally divided in two.
