Analysis of Sonnet # 58

In poetry beauty and the meaning deep.
The bird that sings; it's spring and roses are.
The peaceful look of children when they sleep.
And when high in the sky we see that star.
The sweetness of a kiss when one's in love.
The woman's tears when she to child gives birth.
The friendly meaning of the lovely Dove.
The look upon the face when there is mirth.
Which of these things does move the most the heart?
Which of these things the deepest in the mind?
The person blind the Maker of great art.
The child who's lost and does her mother find.
I want to say much more but no, my friend!
Like everything in life, this is my end.
