Answer the following briefly.

Explain the images of contrast presented in stanza 4.

In the 4^th stanza, the poet is shaken out of his dreariness by the small little thrush bird’s joyful wail, and remarks that even though there is so “little cause” to celebrate in such dreary circumstances, the bird makes its “ecstatic sound” regardless of its dull surroundings. He conjectures that there must be some mysterious cause for this uncorrupted sense of faith and hope in nature that the poet himself and all of mankind is oblivious to. That maybe happiness is more related to the inner self than the exterior influences. Even though the greater understanding of true serenity has not arrived upon the poet he cannot ignore the possibility that there may be something beyond his rational wisdom that justifies that music of hope.
