She was most sorrowfully indignant; ashamed of every sensation but the one revealed to her – her affection for Mr. Knightley. – Every other part of her mind was disgusting.

– Jane Austen

Emma, Chapter 47. Captured here is Emma’s emotional turmoil when she becomes aware of the depth of her feelings for Mr. Knightley. Her sudden epiphany comes only after Harriet’s confession of love for Mr. Knightley. It has the effect of rousing Emma to a peak of self-analysis and realization that he is the one for her.
