How does Jane survive?

Jane Eyre is a character of considerable strength, but I think that the force that causes her the most misery is the same one that gives her that strength and, in turn, great happiness. It is primarily Jane's strong desire to do what is right that helps her to survive and eventually end up happy. She is guided by morals and hugely infuenced by religion. The need to see "responsiblity fufilled," (Bronte, 351) causes Jane to leave Mr. Rochester, yet it is also the reason for Jane declining St. John's offer of marriage and returning to Rochester. Jane feels that she is "right when I adhere(d) to principle and law," (Bronte, 390), and that "God directed me to a correct choice," (Bronte, 390). This belief brings her a peace that she would never have experienced had she chosen not to "flee temptation," (Bronte, 345), and the fact that she clung so tightly to what she believed in only adds to her bliss at the end of the novel.
