Redemption Motifs in Fairy tales

The book about Redemption of the prince and princess from their curses.
The interpretation was so deep and in some places I do not know how to connect her writing.
The difference about hero in myth and fairy tale was good
The redemption in animals and burning their skin are quite understandable because we have seen people who are affected by curse will behave like animals and they tend to behave good in the party and they change as soon as they return home. Burning their skin is like killing them or disappearing from us.
I do not understand some of her interpretations and she gives an explanation that the reader should have symbolic thinking to understand.
