Hello. Unfortunately the texts your question refers to are not available and this makes it impossible for me to answer your question properly. However, I will try to help you as best I can.
To discover the message these two works share, you will need to read both texts. This message is the theme, the lesson that the author of the two texts wants to present to the reader. You can find this message by reading the texts and answering the question "What are these texts trying to teach me?"
I believe the term would be liberation, to liberate, is to receive freedom I believe.
Answer:
In simple words, The Portrait of a Lady refers to the novel from Henry James, initially written in 1880–81 as just a series in The Atlantic Monthly as well as Macmillan's Weekly, and later in 1881 as a volume. This is one of the most famous long books by James, and is deemed also one his best by reviewers.
The Portrait of a Lady is the storey of Isabel Archer, a spirited young American woman, who finds it overwhelming, "confronting her fate." She acquires a significant sum of wealth as well as two American expatriates subsequently become the victim of Machiavellian scheming.
