In this poem he describes an experience of his life.Once he saw a crowd of daffodils flowers beside a lake. The flowers were moving and dancing in the cool breeze.He was delighted to see this beautiful and charming sight. As a result, whenever, he is alone and in a sad mood the same sight comes into his imagination and fills his heart with pleasure. This experience has become a permanent source of pleasure for the poet. He says that daffodils are a bliss of solitude for him.
