Analysis of Song

Nay but you, who do not love her,
  Is she not pure gold, my mistress?
Holds earth aught---speak truth---above her?
  Aught like this tress, see, and this tress,
And this last fairest tress of all,
  So fair, see, ere I let it fall?

Because, you spend your lives in praising;
  To praise, you search the wide world over:
Then why not witness, calmly gazing,
  If earth holds aught---speak truth---above her?
Above this tress, and this, I touch
  But cannot praise, I love so much!
