This can be taken in several ways. The first would be to describe how Wordsworth describes nature. The opening line might assist here. The idea of "wandering" and linking that to the movement of a cloud is powerful because it represents a realm of human freedom without barriers, without borders, without restraints. This conception of human action is one where individuals act on their own volition and little, if anything, can restrain such pursuits. In his description of the flowers themselves, the action verbs of "dancing" and "fluttering" are employed, indicating some type of design or configuration that would permit such a sight to be beheld. Wordsworth's continual description of this natural beauty turns inwards in the subsequent stanzas. It is here where the second line of describing nature can be found. Pay attention to how the speaker describes how nature has impacted him. What has he experienced? How does he identify with the natural phenomena? This is a rather essential articulation of nature because the speaker explains nature through his own experience, and this narrative actually enhances the view of nature that is present.
This poem demonstrates a characteristic aspect of Wordsworth’s thought. He is not a poet who provides botanical details about flowers and trees (though in an early draft of one poem he measures the dimensions of a puddle: "I’ve measured it from side to side. / ’Tis three feet long and two feet wide.") Instead, what Wordsworth seeks from Nature is evidence of divine or universal power. To him, the invisible strength of the universe, together with the consequent shaping of human character, comes mystically through the interactions of human beings and natural phenomena. His thought is that this same mystic power constitutes the subject of poetry and causes the development of the poetic mind.
