Dragons

“Perhaps all the dragons in our lives are princesses who are only waiting to see us act, just once, with beauty and courage. Perhaps everything that frightens us is, in its deepest essence, something helpless that wants our love.” 
― Rainer Maria Rilke, Letters to a Young Poet


I wish I understood what this means.  I LOVE the way the words sound.  The words resonate in my head but I don't get it.  I need examples.
Got any?
