If we read "The Bell Jar" partly as an autobiography, Plath's own life story confirms that the bell jar can descend again "how did I know that someday - at college, in Europe, somewhere, anywhere - the bell jar, with its stifling distortions, wouldn't descend again?" (Plath, Chapter 20). For Esther to act normal, the bell jar would have to be lifted enough for her to breathe. We begin to see a break with Esther's health, there comes a positive change when she wants to kill herself, but she finds her body is more than determined to live. "I am I, am I am," (Plath, Chapter 13). Esther listens to her heartbeat as she contemplates drowning herself, and the heartbeat seems to overpower her minds. This symbolizes her body's want to live and not die.
