Proverbs are the palm-oil with which words are eaten. — Chinua Achebe

As a man danced so the drums were beaten for him.

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. And not only his chi but his clan too, because it judged a man by the work of his hands.

"Let us give them a portion of the Evil Forest. They boast about victory over death. Let us give them a real battlefield in which to show their victory." [...] They offered them as much of the Evil Forest as they cared to take. And to their great amazement the missionaries thanked them and burst into song.
