One day the poet was wandering alone along the side of a lake in a countryside. Suddenly he saw a large number of golden daffodils. These flowers were growing beside the lake, dancing in the breeze and stretching like the stars in the Milky Way. The waves of the lake were also dancing with joy but the daffodils surpassed them. The poet was much delighted to see this beautiful scene.
In the end the poet says that whenever he is in a thoughtful mood, the sight of the daffodils comes into his imagination and his heart is filled with pleasure. Thus a thing of beauty is a joy forever.
