Earth Mother

She's seen as the force responsible for nurturing the soil, giving harvests and prosperity for farmers. She's often worshipped for good weather and fertile land. As spirit of the earth, she protects villages and forests and rules from her Earth Palace.

4 Mother Goddesses

Đạo Mẫu, the tradition which all mother goddesses hail from, orginally existed out of the other 3 mother goddesses. Mẫu Địa's later integration was partly due to local syncretism where Vietnamese mediums began to include earth worship into rituals and spirit mediums starting to become possessed by a seperate Earth Mother, which led to her recognition. Đạo Mẫu started to adopt the Four Palaces, including Earth around the 1800s-1900s.

Domain

She rules over the spiritual underworld (not the same as Địa Ngục, King of Hell's underworld, but the spirtual underworld is rather the temporary 49-day state where souls go before heading to the 'actual' underworld. after the 49 days they go the King of Hell's underworld). Mountains, caves and ancient trees are seen as her homes and she's worshipped at natural shrines or temples.

Origins

(Varies, no universal origin legend) She's one of the primordial mothers, meaning she existed before order was established in the world and that she came out of the cretion of the cosmos. She's said to be a motherly figure who taught the people how to farm, explaining the change of seasons and how important it is to respect the land.
