I Feel As Lit By Fire

I feel as lit by fire a cold countenance
That burns me from afar and keeps itself ice-chill;
A strength I feel two shapely arms to fill
Which without motion moves every balance.
Unique spirit and my minds sole tendance,
Who is undying yet others seeks to kill,
I find one binds my heart, unbound his will,
And for who gladdens only I feel grievance.
How can it be, lord, that a face so lovely
Should work on mine in contrary fashion,
For who has no ill can hardly others harm?
To the glad life that's taken from me,
It behaves, save you forbid it, like the sun,
It heats the world and yet itself's not warm.
