Analysis of Farewell

Farewell! I breathe that wonted prayer,
But oh! though countless leagues divide
Our gaze, our grasp, they shall not tear
My soul, my spirit, from thy side.
Waking or sleeping, thou shalt own
My fervour hovers round thee still;
And when thou deem'st thyself alone,
My whispers shall the silence fill.

And as, in summer's ardent days,
The sun withdraws not all his light,
But, long past setting, twilight rays,
Lingering, illumine half the night;
So shall our Love's enduring glow
Through lonely hours its radiance pour,
O'er our dark lot some comfort throw,
Until we blend and burn once more.
