In "Middlemarch" by George Eliot, the narrative suggests that Rosamund's artistic expression is deeply intertwined with her inner self. It implies that when she creates or performs, a part of her essence is revealed, echoing the connection between art and the soul. This highlights a profound relationship between a person's emotional depth and their ability to convey that through creative endeavors.

The quote emphasizes the role of the interpreter or artist in bringing forth these inner experiences. It indicates that every profound expression has its roots in an active, originating impulse, suggesting that creativity is not only a personal endeavor but also a shared experience with a wider audience. Thus, Rosamund’s art reflects not just her individuality but also a universal human experience that resonates with others.
