| The Quechua world is submerged, so to
speak, in a cosmic magma that weighs heavily upon it. It possesses the rare
quality of being as it were interjected into the midst of antagonistic forces,
which in turn implies a whole body of social and aesthetic structures whose
innermost meaning must be the administration of energy. This gives rise to the
social organism known as the ayllu, the agrarian community that regulates the
procurement of food. The ayllu formed the basic structure of the whole Inca
empire. The central idea of this organization was a kind of closed economy, just the opposite of our economic practices, which can be described as open. The closed economy rested on the fact that the Inca controlled both the production and consumption of food.
