Which lines tell us about the insufferable pain that the poet feels at the thought of the plight of the rural poor?

Explanation

Filled with empathy, the poet is unable to bear the plight of the unassuming and innocent rural people. The lines below show his insufferable pain:

The thought of so much childish longing in vain,
The sadness that lurks near the open window there,
That waits all day in almost open prayer”
