How does Dolores Prida use imagery in Beautiful Senoritas?

In Act II, the Women look at each other as images on a mirror. They discover themselves in each other. The Girl is now one of them. She steps forward to sing: "woman is a fountain of fire, woman is a river of love, a Latin woman is just a woman with the music inside; don't deny us the music, don't imagine my face... I am just a woman breaking the links of a chain... free the butterfly, let the oceans roll in... I am only a woman with the music inside."
