What does Carmen say to Mama that causes Mama to wipe away tears?

Carmen tells mama about her life.... the things she is thankful for. Mama, still grieving over the loss of her husband, leaving her home, and having to leave her mother behind.... relates to what she is saying.

Carmen smiled. “I am poor, but I am rich. I have my children, I have a garden with roses, and I have my faith and the memories of those who have gone before me. What more is there?”
Hortensia and Mama smiled, nodding their heads. And after a few thoughtful moments, Mama was blotting away stray tears.
