Analysis of Lochanilaun

This is the image of my last content:
My soul shall be a little lonely lake,
So hidden that no shadow of man may break
The folding of its mountain battlement;
Only the beautiful and innocent
Whiteness of sea-born cloud drooping to shake
Cool rain upon the reed-beds, or the wake
Of churn'd cloud in a howling wind's descent.
For there shall be no terror in the night
When stars that I have loved are born in me,
And cloudy darkness I will hold most fair;
But this shall be the end of my delight:
That you, my lovely one, may stoop and see
Your image in the mirrored beauty there.
