"I hear it in the deep heart's core"

I wrote my English exam yesterday. Yeats has been on my mind ever since. Thought I would share one of my favourite poems, The Lake Isle of Innisfree. This is a recording of Yeats reciting the poem. It's hauntingly beautiful. What a genius. 

The Lake Isle of Innisfree

I WILL arise and go now, and go to Innisfree,
And a small cabin build there, of clay and wattles made;
Nine bean rows will I have there, a hive for the honey bee,
And live alone in the bee-loud glade.
And I shall have some peace there, for peace comes dropping slow,
Dropping from the veils of the morning to where the cricket sings;
There midnight's all a glimmer, and noon a purple glow,
And evening full of the linnet's wings.
I will arise and go now, for always night and day
I hear lake water lapping with low sounds by the shore;
While I stand on the roadway, or on the pavements gray,
I hear it in the deep heart's core.
