Things Fall Apart
Near the barn was a small house, the “medicine house” or shrine where Okonkwo kept the wooden symbols of his personal god and of his ancestral spirits. He worshipped them with sacrifices of kola nut, food and palm-wine, and offered prayers to them on behalf of himself, his three wives and eight children. (2.14)
The story was told in Umuofia, of how his father, Unoka, had gone to consult the Oracle of the Hills and the Caves to find out way he always had a miserable harvest.
The Oracle was called Agbala, and people came from far and near to consult it. They came when misfortune dogged their steps or when they had a dispute with their neighbors. They came to discover what the future held for them or to consult the spirits of their departed fathers. (3.2-3)
At the most one could say that his chi or personal god was good. But the Ibo people have a proverb that when a man says yes his chi says yes also. Okonkwo said yes very strongly; so his chi agreed. (4.3)
