In Igbo spirituality, Onunu (holes) and Mkpū (mounds) are sacred symbols of creation. Onunu, representing Ogwugwu, is the cosmic womb or spiritual void from which life emerges. Mkpū, reflecting Omumu, is the visible expression of birth and fruitfulness. Mystically, every mound is formed from the earth displaced by a hole—revealing that manifestation always follows descent. This teaching explores the divine unity between Ogwugwu and Omumu, showing how the invisible and visible, the womb and the child, work together to shape reality.
