Analysis of A Divine Mistress

In Nature's pieces still I see
Some error that might mended be;
Something my wish could still remove,
Alter or add; but my fair love
Was fram'd by hands far more divine,
For she hath every beauteous line:
Yet I had been far happier,
Had Nature, that made me, made her.
Then likeness might (that love creates)
Have made her love what now she hates;
Yet I confess I cannot spare
From her just shape the smallest hair;
Nor need I beg from all the store
Of heaven for her one beauty more.
She hath too much divinity for me:
You gods, teach her some more humanity.
