Through The Force, Things You Will See
Yoda: Concentrate. Feel the Force flow. Yes. Good. Calm. Yes.
Through the Force, things you will see. Other places. The future. The past. Old friends long gone.
Luke: Han. Leia.
Yoda: Control, control. You must learn control.
Luke: I saw a city in the clouds.
Yoda: Friends you have there.
Luke: They were in pain.
Yoda: It is the future you see.
Luke: Future? Will they die?
Yoda: Difficult to see. Always in motion is the future.
Luke: I've gotta go to them.
Yoda: Decide you must how to serve them best. If you leave now, help them you could... but you would destroy all for which they have fought and suffered.
