When writing an essay on a work of literature, it is important to use quotes from the text to support any arguments. Quotes should be selected carefully to give strong textual evidence while not clogging the essay with unnecessary or irrelevant material. Some literary quotes have a clear meaning, but it may be necessary research further to interpret what the author meant.
