Answer: The joy the speaker feels when reflecting on seeing the cheerful daffodils.
Step-by-step explanation:
In William Wordsworth's poem, Daffodils (I Wandered Lonely As A Cloud), the speaker describes his discovery of a field of daffodils beside a lake. This was a rather peaceful and joyful experience for the speaker.
In the final stanza, the speaker argues that although he does not currently see the daffodils, they will always remain in his memory - ''they flash upon that inward eye''. He will always remember the emotions he felt when he saw the daffodils, and thus experience happiness once again. This suggests that the speaker has possibly encountered the daffodils in a dream, or have had a heavenly experience. Be it as it may, it is certain that a field of daffodils is the speaker's place of peace.
