Levin is described as a plain, simple man, defined by his religion and his duty to the country. He is the true hero of the novel.
Levin, who becomes depressed over Kitty's rejection, goes to visit his brother Nicholas, who is ill. He begins to realize, after seeing his brother, that Nicholas has always been a victim of ills, including both sickness and poverty. Levin begins to regret getting caught up in his own passions, because he realizes he should be more concerned with his brother's problems. He finds his brother living with Masha, who is not a legitimate wife, but who acts as one. Levin instantly rejects this lifestyle, but he knows that Masha takes good care of Nicholas. He decides to ask Nicholas and Masha to come stay with him, promising himself that he'll forget his mindless passions and devote himself to more important things.
Levin returns to the country and begins to get his life in order. He tidies up his farm, tries to forget about Kitty, and spends some time with his brother. Levin seems different when he is at home in the country--more at peace with himself and his decisions.
