What kind of place is Innisfree? Think about:
(i) the three things the poet wants to do when he goes back there (stanza I);
(ii) what he hears and sees there and its effect on him (stanza II);
(iii) what he hears in his “heart’s core” even when he is far away from Innisfree (stanza III).
(i) The three things the poet wants to do when he goes back there (stanza I):
In the first stanza, the poet expresses his desire to go to Innisfree, where he wants to:
(ii) What he hears and sees there and its effect on him (stanza II):
In the second stanza, the poet describes the sights and sounds of Innisfree:
The effect on the poet is that these natural sounds and sights fill him with a deep sense of peace and contentment, helping him to escape the stress and noise of the outside world.
(iii) What he hears in his “heart’s core” even when he is far away from Innisfree (stanza III):
In the third stanza, even when the poet is far away from Innisfree, he can still hear its peaceful sounds in his heart. The poet says:
"And I shall have some peace there, for peace comes dropping slow, Dropping from the veils of the morning to where the cricket sings."
This shows that the memory of Innisfree and its calming influence stays with him, even in his absence. The poet feels that the essence of Innisfree — the peace, the sounds of nature, and the solitude — is embedded in his heart, and it continues to soothe him even when he is far away.
