Answer:
To provide the reader with a particular context on the narrative voice's feelings towards books.
Step-by-step explanation:
This passage, as the conclusion sentence states ("...tears of love filled my eyes at my selflessness.") expresses how the experience of reading may be so fulfilling that it may lead to tears. In this sense, the author states reading as a selfless process because it allows readers to have strong feelings towards characters regardless of their own feelings. This experience is also portrayed as an evasive experience as the narrative voice suggests: "...and to share their joys and fears, was a chance to exchange the Southern bitter wormwood for a cup of mead with Beowulf..." This last quote is about how books allow readers to escape their everyday lives in order to discover new worlds.
