ÃÂyá Nlá is the primordial spirit of all creation in Yoruba cosmology. She is believed to be the source of all existence. Iya Nla literally means âÂÂGreat Motherâ in the Yoruba language (ÃÂyá: Mother; Nlá: Big or Great). In The GẹÃÂlẹÃÂdẹàSpectacle: Art, Gender, and Social Harmony in an African Culture, art historian Babatunde Lawal reveals that ÃÂyá Nlá in Yoruba cosmology is the orisha who is the âÂÂMother of All Things, including the deities.â Lawal also asserts that the female principle in nature has been personified as ÃÂyá Nlá (The Great Mother), whereby human beings can relate to one another as children of the same mother.â Teresa N. WashingtonâÂÂs Our Mothers, Our Powers, Our Texts: Manifestations of ÃÂjẹàin Africana Literature, states that ÃÂyá Nlá â the Mother of All, who is also known as Yewájá»ÂbÃÂ, Odù, Odùduwà, and ÃÂjẹàâ is not merely an orisha; ÃÂyá Nlá is the primordial force of all creation.
