In "Tintern Abbey," the speaker's reaction to nature is one of awe. He finds the view from the banks of the river Wye to be jaw-dropping-ly, breathtakingly, almost indescribably beautiful. His breath, at one point, is actually taken away. And once he has his epiphany about the divine "presence" in all of nature, his awe is turned to a kind of piety. He becomes a devout worshipper of Mother Nature.
The "dizzy raptures" felt by the young William are the same in type, but not in kind, as the more transcendental experience of the elder speaker.
