Eragon: "What is the worth of anything we do?"
Saphira: " The worth is in the act. Your worth halts when you surrender the will to change and experience life. But options are before you; choose one and dedicate yourself to it. The deeds will give you a new hope and purpose."
Eragon: "But what can I do?"
Saphira: "The only true guide is your heart."
