Anakin Skywalker: What are midi-chlorians?
Qui-Gon Jinn: Midi-chlorians are a microscopic life-form that resides within all living cells.
Anakin Skywalker: They live inside me?
Qui-Gon Jinn: Inside your cells, yes. And we are symbionts with them.
Anakin Skywalker: Symbionts?
Qui-Gon Jinn: Life-forms living together for mutual advantage. Without the midi-chlorians, life could not exist... and we would have no knowledge of the Force. They continually speak to us... telling us the will of the Force. When you learn to quiet your mind, you'll hear them speaking to you.
Anakin Skywalker: I don't understand.
Qui-Gon Jinn: With time and training, Ani, you will. You will.
Qui-Gon Jinn: I have encountered a vergence in the Force.
Yoda: A vergence, you say.
Mace Windu: Located around a person?
Qui-Gon Jinn: A boy. His cells have the highest concentration of midi-chlorians I have seen in a life-form. It is possible he was conceived by the midi-chlorians.
Mace Windu: You refer to the prophecy of the one who will bring balance to the Force. You believe it's this boy?
Qui-Gon Jinn: I don't presume to...
Yoda: But you do. Revealed your opinion is.
Anakin Skywalker: You're a Jedi knight, aren't you?
Qui-Gon Jinn: What makes you think that?
Anakin Skywalker: I saw your laser sword. Only Jedis carry that kind of weapon.
Qui-Gon Jinn: Perhaps I killed a Jedi and took it from him.
Anakin Skywalker: I don't think so. No one can kill a Jedi.
Qui-Gon Jinn: I wish that were so.
