Eingana

The first being we call Eingana. We call Eingana our Mother.

Indigenous peoples... are the traditional guardians of the Law of Mother Earth, a code of conservation inspired by a universally held belief that the source of all life is the Earth, the Mother of all creation.

The people of the oldest continuing culture on the earths face, the Australian natives, name Eingana the Mother as the creator, maker of all water, land, animals, and kangaroos, This huge snake-goddess still lives, they say, in the ocean, rising up occasionally to create yet more life.
  At first, Eingana vomited living beings from her mouth.  Then, dissatisfied with this method of birth, she swallowed them again.  The primordial snake had no vagina; as her offspring grew inside her, the goddess swelled up.  Eventually, tortured with the pregnancy, Eingana began to roll around and around.  The god Barraiya saw her agony and speared her near the anus so that birth could take place as all creatures now give birth.  From Eingana poured her reborn creatures, which were chased by a dingo and took on their earthly forms as they flew, ran, or hopped away.
  The birth mother to these aboriginal people is also the death mother.  They say Eingana holds a sinew of life attached to each of her creatures; when she lets it go, that life stops.  If she herself should die, they say everything would cease to exist.

Another snake goddess of the Aborigines in Australia is Julunggul. She is called also Kungpipi, Kalwadi, and Her ritual name is Mumuna. She is a rainbow snake goddess capable of assuming male, neuter, or androgynous form as well. She is embodied in the pearls, crystals, the ocean, waterfalls, and the deep pools where She lives. She is eternally pregnant which is a parallel with Eingana. She is a goddess of initiation (a second birth to the Aborigines) and puberty. At initiation young boys were symbolically swallowed and regurgitated out as young men. In Her legend She came to Arnhem Land in Australia in Dreamtime from a sinking land. Another similarity with Eingana is seen with Her in the legend of the Wawalag Sisters who violated a taboo concerning menstrual blood near Her lair. For this She continually eats and vomits forth the Sisters in Dreamtime.
