Vergere: "Light and dark are no more than nomenclature: words that describe how little we understand. What you call the dark side is the raw, unrestrained Force itself: you call the dark side what you find when you give yourself over wholly to the Force. To be a Jedi is to control your passion…but Jedi control limits your power. Greatness—true greatness of any kind—requires the surrender of control. Passion that is guided, not walled away. Leave your limits behind."
Jacen: "But—but the dark side—"
Vergere: "If your surrender leads to slaughter, that is not because the Force has darkness in it. It is because you do."
Jacen: "Me? No—no, you don't understand—the dark side is, it's, it's, don't you see it? It's the dark side. The dark side…"
Vergere: "The only dark side you need fear, Jacen Solo, is the one in your own heart."
