Okonkwo still regrets leaving what he had in his own clan. He does not feel that he will be able to rise to what he was before he left and he probably won’t.
It was custom for a man to build his obi and the walls of his compound for himself or inherit them from his father.
Okonkwo calls for a feast to thank his motherland for the time he spent there. He wants to go overboard with the feast because of how good they have been to him. This shows his overwhelming gratitude for people that do him good.
An old member of the umunna rose and spoke about how the people have allowed a new faith to take them over. He is similar to Okonkwo in not welcoming new ideas and instilling fear into the clanspeople.
