Toltecayotl is a Nahuatl word derived from "tōltēcātl" which as used by the Nahuas to refer to the members of the Toltec civilization that preceded them in the basin of Mexico, as well as a generalized meaning of "artisan".
The introduction and dissemination of that title in the academic world is due to anthropologist Miguel León Portilla who, in 1980, published a book titled Tōltēcayōtl, aspects of the Nahuatl culture.
León Portilla's interpretation of the concept of Toltecayotl is based on a set of principles that were collected in the Huēhuehtlahtōlli or 'book of the ancient words', which includes traditional parliaments preserved by oral tradition and other documents. The main are the following:
Be very careful to seek friendship from He who is everywhere and is invisible and impalpable. Be at peace with all; under no circumstances humiliate another person. Do not waste the time which has been granted to us in this world, neither day nor night, because time is very necessary.
This way you shall become Toltec: If you acquire habit and custom to consult everything with your own heart.
Toltequity is also the generic name given to the tōltēca knowledge, or knowledge left by the ancient inhabitants of Tollan-XicocotitlanTula ("Tollan-Xicocotitlan") (Hidalgo, Mexico). Not used in University environments, nor in archaeological analysis (see "Tōltēcayōtl, aspects of the Nahuatl culture" from Miguel León-Portilla, anthropologist and Mexican historian and leading authority in the field of thought and literature Nahuatl. Since 1988 he is emeritus researcher at the National Autonomous University of Mexico.)
The historical validity of toltequity as such tends to be controversial, historians do not even agree in the Toltec city which is known as such, Tula is usually considered (the settlement known as the "Chico") as the base around year 550, and is closely related to the Quetzalcoatl history, while there are four origins, all agree in that he was a King, son of Mixcōātl and Chimalma, and who later was worshipped as God, and later would become one of the main gods in the Anahuac. While the Toltec gave rise to the founding of a legendary city called Tula or Tōllan ("Tōl-+-tlan" = Capital, the name of the Toltec city itself was "Xicocotitlan").
