Anecdotes
Toci bore the nickname "Our Grandmother

the Mother of the gods." For the Aztecs, she embodied the Earth itself, both a source of life and a tomb to which the dead returned.
Each year, during the festival of Ochpaniztli (the "sweeping
)
the Aztecs cleaned houses and temples to honor Toci. A woman was chosen to impersonate the goddess during the ceremonies
then sacrificed: her skin was worn by a priest
symbolizing the renewal of the earth before the harvests.
Toci was the protector of midwives (the ticitl) and healers. Women who helped with childbirth invoked her, for birth was compared to a battle: the mother was seen as a "warrior" capturing a new being.
Toci was also the patroness of the temazcal, the Aztec steam bath. Her image was often carved above the entrance of these sweat lodges, for heat and water served to heal the sick and purify the body, domains placed under her protection.
Soldiers and physicians saw Toci as a dual figure: a goddess of healing but also tied to war. She was nicknamed "Heart of the Earth
(Tlalli iyollo)
for she beat at the center of the world and nourished all living beings.
