Ìyá Nlá The Source - Primordial Yoruba Mother" is a sacred and intellectual text written by Iyalaja Ileana Alcamo that explores the presence, essence, and worship of the divine feminine in Yoruba cosmology. The book examines Ìyá Nlá (literally translating to "Great Mother") as the supreme primordial womb, the ultimate life force, and the source from which all living beings, nature, and the Orishas (deities) originate.
