In Anna Karenina, Leo Tolstoy presents marriage in a realistic sense, marriage is not an easy institution; couples must overcome difficult times in order to be strong; it also presents passion as a force that can have a positive influence, but simultaneously presents passion as a factor that can have a corrupting power over a person's life. These two couples, Levin and Kitty and Vronsky and Anna, are compared throughout the novel. Levin and Kitty differ from Anna and Vronsky because they do not communicate in the same way. Kitty and Levin try to solve problems as they arise, so as not to create bigger problems. Another difference is that Anna and Vronsky are protected by society due to Anna's position as a fallen woman. Both couples have children, Levin and Kitty raise their son; however, Anna and Vronsky pay little attention to their daughter. Their relationships have drastic differences. Where the relationship between Anna and Vronsky is based on passion, that between Levin and Kitty is more spiritual. One of the key aspects of Kitty and Levin's relationship that is missing from Anna and Vronsky's relationship is communication. When problems arise in Levin and Kitty's marriage, they try to resolve them by talking to each other and seeking a solution to the problem. An example is when Levin contracts cold feet syndrome before getting married. Levin begins to wonder, "suppose she doesn't love me" (pg.404). Even though it is not customary for the groom to see the bride until the wedding begins, he goes to talk to Kitty. The problem is solved. This set the tone for their relationship because whenever an issue comes up, they talk about it. Another example involves Kitty seeing Vronsky for the first time... halfway through the paper... no problem arises and this results in a successful marriage. Because of Anna's affair, she and Vronsky are not accepted by society. Children also get involved in every relationship. Kitty and Levin are very worried parents; while Anna and Vronksy don't even take care of their child. Infatuation with passion can “lead to final destruction…” (Gromeka, page 769). Passion can completely alter a person's life, as is the case with all of these characters presented. Anna's passion for Vronsky leads to her death. At the end of the novel, Vronsky feels as if Anna is his only reason for living, and due to her death, he commits suicide by joining the army. On the other hand, passion can have a positive influence, as in the case of Kitty and Levin. They become close and this eventually leads to their marriage, which causes both of them to become confident people.
