Analysis of How do I love thee

How do I love thee? I love thee to the ends of the world
To the purity of my soul , and where it's pure light leads me
I love thee to the heights of the sky, the length and breadth of the seas
Where the full contents of my heart is laid out plainly, and its darkness casted out free
I love thee even when I am sober with your love, thus, you're the reason I need to love thee
When the weather becomes too temperate, and your touches cold
I love thee to the extent I still pray and pray
I love thee to the length I give up my youthful days
I love thee with the imagination of my foolish youthfulness
To live in harmony in your old pale yet lovely arms
As though loving you will be easy, I am ready to love thee at whatever cost.
