In “Lines Composed a Few Miles Above Tintern Abbey”, Wordsworth reflects on how Nature in its many forms — pastures, woods, mountains, and more — has deeply influenced his spiritual, emotional, and moral life.
He explicitly says that Nature is:
"...the anchor of my purest thoughts, the nurse,
The guide, the guardian of my heart, and soul
Of all my moral being."
These lines show that all aspects of Nature contribute to grounding his thoughts and nurturing his moral sense.
