I have some trouble analyzing PB Shelley's poem "Mont Blanc", I understand that in the poem, influenced by Wordsworth's "Tintern Abbey", he questions the relation between nature and the human mind. The poem starts with the speaker being caught up in staring and taking in the mountain, the giant wonder of nature, he then goes on to personify the mountain otherwise it is too big to grasp. He draws parallels between this amazing creation of nature and that of the mind, right? In Stanza 1, the speaker then brings forth the central problem about understanding the nature of the power of "the everlasting universe of things" by employing the river as a metaphor, because, like human understanding, the river has had the ability to cut through the mountain over time, even though it started as a "feeble" brook. Now, what I can't grasp is the relation between the metaphor of river and "the everlasting universe of things"? What is exactly implied by the latter? Any help is appreciated, thank you in advance.
As opposed to William Wordsworth's "Lines Composed A Few Miles above Tintern Abbey" in which the poet compares his present adult experience of nature with the "haunted" passionate experience he had as a youth who "bounded o'er the mountains," Shelley's mind prevails in his discussion of nature and is both rational and creative. Moreover, for Shelley, it is the mind that provides nature its meaning: the mind lends itself and nature the "sublime" experience. For, in the final lines, Shelley asks,
And what were thou, and earth, and stars, and sea,If to the human mind's imaginingsSilence and solitude were vacancy?
from secret springs
The source of human thought its tribute brings
and one majestic River,
The breath and blood of distant lands--
