Derry says 'Ita not what you look like its what you are inside'. What are the qualities this sentence encourages people to have?

Derry says that what really mattered was the kind of person one was inside rather than what was discernible on a superficial level on their face. Handsomeness came from within. Derry states the example of how beauty loved the monstrous beast for himself and when she kissed the beast, he changed into a handsome prince. There was power and beauty that came from the goodness within and it had nothing to do with how the person looked.
