The Foundational Idea

1. The bones and the blood

Every system starts from an image. Here it is, from the Leyenda de los Soles (1558):

The world has already been destroyed four times. Four previous humanities have been lost. Quetzalcoatl descends to Mictlan, the underworld, to ask for their bones.

The lord of Mictlan sets him tests, deceives him, sends quail. Quetzalcoatl stumbles; the bones fall and break. That, the text says, is why human beings are not all the same height.

He gathers them broken. They are taken to Cihuacoatl, who grinds them in a clay bowl. And then Quetzalcoatl bleeds himself over them.

From that blood, human beings are made.

What falls out of this

First: humans were not created — they were acquired at a price. And the language keeps this in a striking way.

The word for the common person is macehualli. It connects with the verb macehua, which means “to acquire something through penance, sacrifice, or merit”.

A human being, in Nahuatl, is literally “the one won through sacrifice”.

You are not a creature. You are an acquisition — and someone paid.

Second: debt is the foundational relation. The term for sacrifice is nextlahualli — “payment, settlement of a debt”. It is not a gift, not an atonement, not worship. It is a bill.

Third: the body is not yours. It is on loan, temporary, from material that belongs elsewhere and is returned.

And why this changes everything

A system that starts from debt does not ask the same questions as a system that starts from balance or from perfection.

It does not ask “how do I become better?”. It asks:

“What do I owe, to whom, and am I aware of it?”

Health is not cultivated — it is restored. Disease is not dysfunction — it is an open account. And treatment, almost always, is a form of settlement or return.

Hold on to this. You will find it in chapter 11 (pollution), chapter 17 (loss of tonalli), chapter 24 (sacrifice) — and it is why this document is called what it is.

2. Teotl: not god, but process

teotl — the word the Spanish translated as dios, “god”. And here the difficulty begins.

In the texts, teotl is used for things that are not gods in the Western sense: for the sun, for a sacred mountain, for a person chosen for sacrifice, for something astonishing or terrifying. The Spanish were first called teteo (the plural).

The reading that is gaining ground

The philosopher James Maffie (Aztec Philosophy, 2014) argues that teotl is not an entity but a process: a continuous, self-generating, self-transforming sacred power of which everything that exists is made.

That is: there are not many gods acting upon the world. There is one thing in constant motion, and the “gods” are faces, masks, modes of its manifestation.

The fact that the figures of the gods continually overlap, swap attributes, and are sometimes the same god under another name, supports this reading. So does one of the names of Tezcatlipoca: Yohualli Ehecatl — “Night, Wind”. That is: invisible and tangible at once.

The honest note

This is an interpretation, not a source. Maffie is disputed: he is accused of over-systematising, and of importing concepts of Western process philosophy (Heidegger, Whitehead) into material that does not have them explicitly.

The most likely position is that both existed — a popular religion with faces and names, and an esoteric discussion in the schools of the nobility (calmecac) that tended toward unification. Exactly as happens in every developed tradition.

How to take it practically: when the text says “god”, do not imagine a person on a throne. Imagine a force in operation — and a relationship with it that has terms.

3. The inamic pairs

inamic — “the counterpart, the opposite, the match”. Used for the spouse, for the enemy, and for the price of a commodity (what counterbalances it).

And here is the structural principle that runs through the whole system:

Opposites do not fight for one to prevail. They are simultaneously necessary, and reality arises from the tension between them.

The basic pairs:

• life ↔ death
• male ↔ female
• dry ↔ wet
• sun ↔ moon
• light ↔ darkness
• order ↔ disorder
• sky ↔ earth
• hot ↔ cold

The image that best shows it

The highest thing in the cosmology is not a god. It is a couple: Ometeotl or, more accurately, Ometecuhtli and Omecihuatl — “Lord Two” and “Lady Two”, who dwell in Omeyocan, “the Place of Duality”.

Ome means “two”. The principle of all things is, by name, the two.

(Note: the form “Ometeotl” as a single name has been contested — there is an argument that it is largely a construction of Miguel León-Portilla. The dual structure, however, is securely attested.)

The crucial difference from “balance”

It is not balance in the calm sense. It is unresolved antagonism.

The sun must defeat the night every day, again, and there is no guarantee. The present world — the Fifth Sun — is the fifth because the four preceding ones failed. And this one too will be destroyed, by earthquakes.

There is no stability. There is only maintenance — and it is strenuous, collective, and precarious.

This is the strangest idea of the system for a modern mind, and the most important. The world does not stand on its own.

4. Three ways of motion: olin, malinalli, nepantla

If teotl is continuous motion, the question becomes: what kind of motion?

Maffie identifies three recurring patterns, each with a name that is simultaneously a day of the calendar and a natural process. (Again: this is his systematisation, not an explicit category of the sources. The names themselves and their meanings, however, are genuine.)

olin — oscillation

ollin = motion, earthquake, pulse. The same root as yollotl, “heart”, and as olli, the rubber from which the ball of the ritual game was made.

It is the oscillating motion around a centre: the heartbeat, the breath, the ball that bounces, the sun that rises and sets, the earthquake.

Its shape is the four with a centre — four directions and a middle. And the present world is called Nahui Ollin, “Four-Motion”.

malinalli — twisting

malinalli = twisted grass, the thread that is spun. The motion of the spiral: two fibres that twist around each other and become a rope — stronger than their sum.

It is the motion of conversion: life into death and back, food into flesh, plant into thread. The image of the double helix appears continually in the iconography.

nepantla — the in-between

nepantla = “in the middle, between”. The motion of weaving: two threads that constantly pass through one another and produce cloth, without either being lost.

It is the most interesting of the three, and it returns in the last chapter — because after the conquest the same word described the position of the Nahua themselves.

Why it matters for the body

Because all three exist inside you:

• olin — heart, breath, rhythm, the up-and-down of the day
• malinalli — digestion, nutrition, ageing, the becoming-flesh
• nepantla — relation, being between people, the coexistence of opposites in you

The body is not a thing in this model. It is three motions happening simultaneously.
