Yemaya is a mother goddess, the goddess of home, fertility, love and family. Like water she represents both change and constancy bringing forth life, protecting it, and changing it as is necessary.
the creator Olodumare first created a mortal god-human, Obatala, and gave him a wife. Their children were Yemaya and Aganyu, who had a son together. They named him Orungan. As a teenager Orungan rebelled against his father and brutally raped his mother. When he tried to rape Yemaya a second time, the river goddess fled to a nearby mountaintop where she cursed her son until he died. In sorrow she chose to end her own life on the summit of the mountain. As she died she gave birth to fourteen powerful orisha. When her waters broke it caused the great flood that inundated the world and created the seven seas. Obafulom and Lyaa, the first human male and female and the ancestors of all humans.
Yemaya is the mother of us all. She owns the seas and the oceans, and in the beginning the entire Earth was hers. Her songs and her dances are reminiscent of the unceasing undulation of the sea, sometimes gentle and sometimes tempestuous but always powerful. There are seven roads of Yemaya which represent all of her aspects, from the gentle shoreline (Asesu, whose color is pale blue) to the raging depths (Okute, the warrior aspect of Yemaya, whose colors are deep blue with a little red and a touch of clear greenish-blue like the color of churning waves).
