Answer: The beauty of nature causes the author's "perfect exhilaration."
Explanation:
The Nature is Ralph Waldo Emerson's essay about the appreciation of nature, written from a transcendentalist point of view.
In lines 1-20, the author explains his experience upon seeing a wide, open space of "bare" ground. He simply appreciates the beauty of nature he sees, which enables him to clear his mind. As he describes it, he becomes ''nothing'', and is unified with nature. He does not have any thoughts on his mind, and becomes "a part or particle of a God."
The irony in the story was that even though both characters got something for the other person item that they gave away and vice versa, they were actually the smart ones in their lovingness, and this relates to the reader, because it develops the theme of heartfelt care and giving from the heart.
