Abstract
Mesoamerican cosmologies have developed ideas about self using change-in-time as the principal orientation. These approaches conceive existence to be a phenomenon of temporal organization, which is radically different in assumptions and consequences than a metaphysics based on substances. The chief consequence of this is a continuity between human beings-in-time and other living and non- living entities.One 's character and destiny are of a kind with specific animals, meteorological phenomena, places, and objects. The qualities of the timed world and the qualities of the person are one and the same. Understanding oneself,one 's role,and living well results from properly orientating oneself to this metaphysical order by embracing one's 'co-essence'.
