Final answer:
The word "thee" in the poem implies a shift from addressing an audience to a more personal or abstract reflection, suggested by changes in tone and content.
Step-by-step explanation:
The usage of the word "thee" in a poem often reveals the poem's speaker is addressing a specific individual or entity. From the context provided, it seems that in the first half of the poem, "you" is used to address an audience directly, while in the second half, a transition occurs where "thee" may refer to an introspective dialogue or a continued conversation with a less direct audience. This shift suggests a change from outward expression to internal contemplation. Evidence to support this conclusion could be drawn from the text's change in tone and content. The speaker's search for a parallel in their experience to understand and articulate a feeling of awe implies a more personal, reflective approach, hinting that "thee" could be the speaker himself or an abstract concept he is pondering.
