What is the theme in Rappaccini's Daughter by Nathaniel Hawthorne?

The story states a huge emphasis on achieving balance in one's life. When Giovanni first arrives in Padua, though naive, he has obviously spent a lot of his time concentrating on his intellectual side and not enough time on his more romantic passionate side. Consequently, the garden and the beautiful Beatrice fascinate him, seeing them as a vehicle he can discover that underdeveloped side of himself.
