“Odudua’s themes are kinship, unity, devotion, creativity, community, love and fertility. Her symbols are black items. In the beginning, Odudua created the earth and its people. In Yoruban tradition, She presides over all matter of fertility, love and community. Her sacred color is black.
The African American festival of Kwanzaa celebrates family unity and the black culture. It is also a harvest festival whose name means ‘first fruits’. Every day of the celebration focuses on important themes, including Odudua’s harmony, determination, community responsibility, purpose, creativity and faith.
One lovely tradition easily adapted is that of candle lighting. Each day of the festival, light one red, green or black candle (the colors of Africa). Name the candle after one of Odudua’s attributes you wish to develop (try to choose the color that most closely corresponds to your goal). Igniting it gives energy and visual manifestation to that principle. Also try to keep one black candle lit (in a safe container) to honor the Goddess’s presence during this time.
To inspire Odudua’s peaceful love in your heart and life today, wear something black. This will absorb the negativity around you and put is to rest.”

Patricia Monaghan said that this “primary mother Goddess of the Yoruba of Nigeria…is the great orisha (deity) of the earth as well as its creator. Her name means ‘She who exists for Herself and to create others,’ and it was Her energy that caused the primal matter which later formed itself ionto this universe. The spot where She descended from the sky onto the new earth is still pointed out in Yourbaland. Oddudua is called Saint Claire in Santería” (p. 238).
On mythologydictionary.com, it states: “A creator-Goddess and war-Goddess of the Yoruba. Wife and sister (or, some, say, daughter) of Olodumare or Obatala. Mother of Aganju, Ogun and Yemoja. Some regard her as the founder of the Yoruba. In some accounts, Oduduwa is regarded as male, son of Lamurudu and brother of Obatala, marrying Aje and fathering Oranyan; in others She is female in which role Her father sent Her to earth to sow seeds and She became the wife of Orishako. In some references, called Oduduwa, Odudua or Odudua.
