This photograph is part of the record of the performance "Material de estudio" where the artist remains exposed in a hostile environment. The work seeks to address the physical imbalance as a reflejo of emotional imbalance. Reinterpreting a mind limited by its bias, which seeks harmony between its own body and the immediate environment. It follows the idea of recomposing space through the body. The action seeks symbiosis between the body and the stones, while the artist's stomach is deformed. Weil "everything is a matter of sacrifices".
