The narrator tells us that Tereza has a desire to fall, even though she fears death. In class we decided that she might be desiring death, even though she is not actively seeking it. We found a few points in her life that might have caused this "desire to fall", however, I believe the main reason is due to the fact that she was not really valued as a child by her mother. Tereza is looking for someone to fill this void in her life, and I believe that because of this she attaches herself to Tomas.
However, this void is still there and she feels this "lack of worth." Death, she might think, would be light in a sense, but then again it could also be heavy in way. Death might
symbolize the middle ground between light and heavy and it could symbolize
peace, the peace she is looking for to fill the void in her life. Also, since Tereza is so obsessed with her body, she might want to die in
order to get rid of her body (soul body split) wherein she would be separated
from her body. This desire would certainly represent the motif of soul body split in the novel.
