In this installation, sculptures and symbolisms of Early Horizon cultures, such as the Chavín, Nazca and Moche, are reproduced in reference to the ancestral ritual of ingesting the hallucinogenic Achuma cactus, renamed "San Pedro" during the Spanish colony. It is said that the name is due to the fact that the cactus "opens the gates of heaven", and in the Christian tradition this saint keeps the key.

Sand is spread from the center to the walls, forming stenciled geometric patterns on the floor, repeating the ornaments of a set of objects that emerge from a central mound. It is an installation in which people must decide to step on the sand to walk through it, being able to leave footprints and to modify it.
