What is Ekwefi strongest characteristic in the novel Things Fall Apart?

It is not a single quote, but a combination of ideas that give this feeling of mentorship. Not only is Uchendu Okonkwo's uncle, but he is a successful man in his own right. He is older, wiser, and has had more wives than Okonkwo. Moreover, he has the power to call together his sons, daughters and Okonkwo. He has the first right to speak during this meeting. He challenges anyone to say that they know more than he does, but they do not. He asks Okonkwo a question, but Okonkwo does not know the answer, at which point he calls Okonkwo still "a child." Uchendu eventually answers his own questions, and ends the conversation unilaterally.
