For oft when on my couch I lie
In vacant or in pensive mood,
They flash upon that inward eye
Which is the bliss of solitude;
And then my heart with pleasure fills,
And dances with the daffodils.

In this passage from "I Wandered Lonely as a Cloud," Wordsworth captures the power of memory to instill joy and inspiration long after experiencing a moment of beauty. The "inward eye" functions as a mental canvas where past images of nature's splendor are vividly recalled, especially during introspective or idle times. This reflection becomes "the bliss of solitude," suggesting that even in loneliness, one is never truly alone; the mind's collection of past beauty offers companionship and delight. Wordsworth’s heart, when thus filled with pleasure, imaginatively "dances with the daffodils," bridging the gap between past experience and present emotion. This interaction with memory underscores the poem's theme that nature's beauty is an enduring source of happiness and artistic inspiration. Through the vivid recollection of a simple, joyful scene, Wordsworth illustrates poetry's potential to transform the mundane into moments of profound insight.
