Encountered in: “The Story of an Hour” by Kate Chopin (12th paragraph)
Quote: “She did not stop to ask if it were or were not a monstrous joy that held her. A clear and exalted perception enabled her to dismiss the suggestion as trivial”
Now that Mrs. Mallard has expressed that she is “free, free, free!”, with a clear understanding of the word exalted, the sentence explains how she feels a higher level of self to omit if the joy kept her or not.
