Wordsworth defined poetry as spontaneous overflow of powerful feelings. Now this line captures our hearts and takes us along with the poet into the world of the nightingale to listen to the song of the nightingale which is so melodious, so happy and so free. My sense, as though of hemlock I had drunk, My heart aches, and a drowsy numbness pains Keats, for example, in the opening line of one of his most famous odes ‘Ode To a Nightingale ‘ says All of you would have read poetry that would have touched your hearts where the poet has transported you into another world- a world of imagination which takes us away far away from the real world in which we live.
